Wheels and Tires
General information
The combination of a rim and tire will be referred to as a wheel in this Owner’s Manual. If only one of the components is referred to, then the term tire or rim will be used.
>Check your tires regularly for damage, such as punctures, cuts, cracks, and bulges. Remove foreign objects from the tire tread.
>If driving over curbs or similar obstacles, drive slowly and approach the curb at an angle.
> Have faulty tires or rims replaced immediately.
>Protect your tires from oil, grease, and fuel.
>Mark tires before removing them so that the same running direction can be maintained if they are reinstalled.
> Lay tires flat when storing and store them in a cool, dry location with as little exposure to light as possible.
WARNING —Never drive faster than the maximum permitted speed for your tires. This could cause the tires to heat up too much. This increases the risk of an accident because it can cause the tire to burst.
—Always adapt your driving to the road and traffic conditions. Drive carefully and reduce your speed on icy or slippery roads. Even winter tires can lose traction on black ice.
Note —Please note that summer and winter tires are designed for the conditions that are typical in those seasons. Audi recommends winter tires during the winter months. Low temperatures significantly decrease the elasticity of summer tires, which affects traction and braking ability. If summer tires are used in very cold temperatures, cracks can form on the tread bars, resulting in permanent tire damage that can cause loud driving noise and unbalanced tires.
Wheels
—Burnished, polished or chromed rims must not be used in winter driving conditions. The surface of the rims does not have sufficient corrosion protection for this and could be permanently damaged by road salt or similar substances. The exception to this are rims that are part of complete winter wheels provided by the factory.

Uniform Tire Quality Grading is a tire information system developed by the United States National Highway Traffic Safety Administration (NHTSA) that is designed to help buyers make relative comparisons among tires. The UTQG is not a safety rating and not a guarantee that a tire will last for a prescribed number of miles (kilometers) or perform ina certain way. It simply gives tire buyers additional information to combine with other considerations, such as price, brand loyalty and dealer recommendations. Under UTQG, tires are graded by the tire manufacturers in three areas: treadwear, traction, and temperature resistance. The UTQG information on the tires, molded into the sidewalls.
U.S. DOT Tire Identification Number (TIN) This is the tire’s “serial number”. It begins with the letters “DOT” and indicates that the tire meets all federal standards. The next two numbers or letters indicate the plant where it was manufactured, and the last four numbers represent the week and year of manufacture. For example,
DOT...2222...
Wheels
means that the tire was produced in the 22nd week of 2022. The other numbers are marketing codes that may or may not be used by the tire manufacturer. This information is used to contact consumers if a tire defect requires a recall.
Vehicle capacity weight means the rated cargo and luggage load plus 150 lbs. (68 kilograms) times the vehicle's designated seating capacity.
Vehicle maximum load on the tire

Refer to the tire inflation pressure label > page 242, fig. 145 for the number of seating positions. Refer to the table > table on page 243 for the number of people that correspond to the vehicle normal load.
New tires or wheels
Audi recommends having all work on tires or wheels performed by an authorized Audi dealer or authorized Audi Service Facility. These facilities have the proper knowledge and are equipped with the required tools and replacement parts. >New tires do not yet have the optimal gripping properties. Drive carefully and at moderate speeds for the first 350 miles (500 km) with new tires.
> Only use tires with the same design, size (rolling circumference), and as close to the same tread pattern as possible on all four wheels.
> Applies to: RS models: Only use tires with the same design, size >
Wheels
(rolling circumference), and the same tread pattern on all four wheels. The dimensions of the wheels installed may differ between the front and rear axle.
>Do not replace tires individually. At least replace both tires on the same axle at the same time.
> Audi recommends using Audi Genuine Tires. If you would like to use different tires, please note that the tires may perform differently even if they are the same size > A.
>If you would like to equip your vehicle with a tire and rim combination that is different from what was installed at the factory, consult with an authorized Audi dealer or authorized Audi Service Facility before making a purchase > A.
Because the spare tire* is different from the regular tires installed on the vehicle (such as winter tires or wide tires), only use the spare tire* temporarily in case of emergency and drive carefully while it is in use. It should be replaced with a regular tire as soon as possible.
Applies to: vehicles with all wheel drive: All four wheels must be
equipped with tires that are the same brand and have the same construction and tread pattern so that the drive system is not damaged by different wheel speeds. For this reason, in case of emergency, only use a spare tire* that is the same circumference as the regular tires.
WARNING —Only use tire/rim combinations and suitable wheel bolts that have been approved by Audi. Otherwise, damage to the vehicle and an accident could result.
—For technical reasons, it is not possible to use tires from other vehicles. In some cases, you cannot even use tires from the same vehicle model.
—Make sure that the tires you select have enough clearance to the vehicle. Replacement tires should not be chosen simply based on the nominal size, because tires with a different construction can differ greatly even if they are the same size. If there is not enough clearance, the tires or the vehicle can be damaged
Wheels
and this can reduce driving safety and increase the risk of an accident.
—Only use tires that are more than six years old when absolutely necessary and drive carefully when doing so.
—Run-flat tires* may only be used on vehicles that were equipped with them at the factory > page 253.
—If you install wheel covers on the vehicle, make sure they allow enough air circulation to cool the brake system. If they do not, this could increase the risk of an accident.
—Mounting a tire on the rim incorrectly can result in tire damage or failure. To reduce the risk of an accident, only trained personnel may mount a tire on the rim.
Tire wear and damage DN
Fig. 143 Tire profile: treadwear indicator
Tire wear Check the tires regularly for wear.
—Inflation pressure that is too low or high can increase tire wear considerably.
—Driving quickly through curves, rapid acceleration, and heavy braking increase tire wear.
—Have an authorized Audi dealer or authorized Audi Service Facility check the wheel alignment if there is unusual wear.
—Have the wheels rebalanced if an imbalance is causing noticeable vibration in the steering wheel. If you do not, the tires and other vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain treadwear indicators in the tread pattern, which are bars that are 1/16 inch (1.6 mm) high and are spaced evenly around the tire perpendicular to the running direction > fig. 143. The letters “TWI” or triangles on the tire sidewall indicate the location of the treadwear indicators.
Wheels
The tires have reached the minimum tread depth ") when they have worn down to the treadwear indicators. Replace the tires with new ones > A.
Tire rotation
Applies to: RS models: The wheels must not be swapped with each other, because the width of the tires or the tread depth may differ between the front and rear axle. If wheels with different tire widths are used, the wider tires must be mounted on the front axle.
Rotating the tires regularly is recommended to ensure the tires wear evenly. To rotate the tires, install the tires from the rear axle on the front axle and vice versa. This will allow the tires to have approximately the same length of service life.
For unidirectional tires, make sure the tires are installed according to the running direction indicated on the tire sidewall => page 267.
1) Obey any applicable regulations in the country where the vehicle is being operated.
Hidden damage Damage to tires and rims can often occur in locations that are hidden. Unusual vibrations in the vehicle or pulling to one side may indicate that there is tire damage. Reduce your speed immediately. Check the tires for damage. If no damage is visible from the outside, drive slowly and carefully to the nearest authorized Audi dealer or authorized Audi Service Facility to have the vehicle inspect-
Tread that has worn too low or uneven tread depths on the tires can reduce driving safety. This can increase the risk of an accident because it has a negative effect on handling, driving through curves, and braking, and because it increases the risk of hydroplaning when driving through deep puddles.

Tire pressure
Fig. 145 Tire pressure label
The correct tire pressure for tires installed at the factory is listed on a label. The label is located on the B-pillar (driver's side) > fig. 144, > fig. 145. The location may vary depending on the model.
Use the tire pressure specified for a normal vehicle load when the vehicle is partially loaded > table on page 243. If driving the vehicle when fully loaded, you must increase the tire pressure to the maximum specified pressure > A\.
Checking and correcting tire pressure >Check the tire pressure at least once per month and also check it before every long drive.
>Always check the tire pressure when the tires are cold. Do not reduce the pressure if it increases when the tires are warm.
>Refer to the sticker > fig. 145 for the correct tire pressure.
>Correct the tire pressure if necessary.
>Store the new tire pressure = page 250 or > page 252.
»Check the pressure in the spare tire (compact spare tire)*. Always maintain the maximum temperature that is specified for the tire.
WARNING Always adapt the tire pressure to your driving style and the vehicle load. —Overloading can lead to loss of vehicle control and increase the risk of an accident. Read and follow the important safety precautions in > page 244.
—The tire must flex more if the tire pressure is too low or if the vehicle speed or load are >
Wheels
too high. This heats the tire up too much. This increases the risk of an accident because it can cause the tire to burst and result in loss of vehicle control.
—Incorrect tire pressure increases tire wear and has a negative effect on driving and braking
behavior, which increases the risk of an accident.
Replace lost valve caps to reduce the risk of damage to the tire valves.
Tire pressure that is too low increases fuel consumption.
Tire pressure table
Please note that the information contained in the following table was correct at the time of printing, and the information is subject to change. If there are any differences, you should always follow the tire pressure sticker => page 242, fig. 144.
Make sure that the tire designation on your tire matches the designation on the tire pressure label and the tire pressure table.
The following table lists recommended tire pressures in cold tires according to the load and the size of the tires installed.
2) Two people in the front, one person in the rear
») The value before the forward slash applies to vehicles with a maximum speed up to
155 mph (250 km/h); the value after the slash is for up to 174 mph (280 km/h) or 180 mph (290 km/h).
Please note the important safety precautions regarding tire pressure > page 242 and load limits > page 244.
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and any tire can carry. A vehicle that is overloaded will not handle well and is more difficult to stop. Overloading can not only lead to loss of vehicle control, but can also damage important parts of the vehicle and can lead to sudden tire failure, including a blowout and sudden deflation that can cause the vehicle to crash.
Your safety and that of your passengers also depends on making
sure that load limits are not exceeded. Vehicle load includes everybody and everything in and on the vehicle. These load limits are technically referred to as the vehicle’s Gross Vehicle Weight Rating (“GVWR”). The “GVWR” includes the weight of the basic vehicle, all factory installed accessories, a full tank of fuel, oil, coolant and other fluids plus maximum load. The maximum load includes the number of passengers that the vehicle is intended to carry (“seating capacity”) with an assumed weight of 150 lbs. (68 kg) for each passenger at a designated seating position and the total weight of any luggage in the vehicle. If you tow a trailer, the weight of the trailer hitch and the tongue weight of ~— >
Wheels
the loaded trailer must be included as part of the vehicle load.
The Gross Axle Weight Rating (“GAWR’”) is the maximum load that can be applied at each of the vehicle’s two axles.
The fact that there is an upper limit to your vehicle’s Gross Vehicle Weight Rating means that the total weight of whatever is being carried in the vehicle (including the weight of a trailer hitch and the tongue weight of the loaded trailer) is limited. The more passengers in the vehicle or passengers who are heavier than the standard weights assumed mean that less weight can be carried as luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the safety compliance sticker label located on the driver’s side B-pillar.
WARNING Overloading a vehicle can cause loss of vehicle control, a crash or other accident, serious personal injury, and even death. —Carrying more weight than your vehicle was designed to
carry will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
—The brakes on a vehicle that has been overloaded may not be able to stop the vehicle within a safe distance.
—Tires on a vehicle that has been overloaded can fail suddenly, including a blowout and sudden deflation, causing loss of control and a crash.
—Always make sure that the total load being transported including the weight of a trailer hitch and the tongue weight of a loaded trailer does not make the vehicle heavier than the vehicle’s Gross Vehicle Weight Rating.
Determining correct load limit
Use the example below to calculate the total weight of the passengers and luggage or other things that you plan to transport so that you can make sure that your vehicle will not be overloaded.
245
Wheels
Steps for Determining Correct Load Limit 1. Locate the statement “THE
COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX LBS” on your vehicle’s placard (tire inflation pressure label) => page 242, fig. 145.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from “XXX” kilograms or “XXX” pounds shown on the sticker => page 242, fig. 145.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs. and there will be five 150 lbs. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5S x 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely ex246
ceed the available cargo and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.
»Check the tire sidewall (= page 232, fig. 142) to determine the designated load rating for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten easily. Rims
Rims with a bolted rim ring* or with bolted wheel covers* consist of multiple pieces. These components were bolted together using special bolts and a special procedure. You must not repair or disassemble them > A\.
Wheel bolts that are tightened or repaired incorrectly can become loose and result in loss of vehicle control, which increases the risk of an accident. For the correct tightening specification, see 2 page 268, Finishing. — Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease. — Only use wheel bolts that fit the rim. — Always have damaged rims repaired by an authorized Audi dealer or authorized Audi Service Facility. Never repair or disassemble
Wheels
rims yourself, because this increases the risk of an accident.
Winter tires significantly improve the vehicle's handling when driving in winter conditions. Because of their construction (width, compound, tread pattern), summer tires provide less traction on ice and snow.
> Use winter tires on all four wheels. > Only use winter tires that are approved for your vehicle.
> Please note that the maximum permitted speed may be lower with winter tires > A\ in General information on page 231. An authorized Audi dealer or authorized Audi Service Facility can inform you about the maximum permitted speed for your tires.
> Check the tire pressure after installing wheels = page 242.
The effectiveness of winter tires is reduced greatly when the tread is worn down to a depth of 0.16 in (4 mm). The characteristics of winter tires also decrease greatly as the tire ages, regardless of the remaining tread.
Reinstall summer tires at the appropriate time, because they provide better handling when roads are free of snow and ice. Summer tires cause less road noise, tire wear, and fuel consumption.
You can also use all season tires instead of winter tires. Please note that in some countries where winter tires are required, only winter tires with the 4a symbol may be permitted.
Snow chains improve both driving and braking in winter road conditions.
» Only install snow chains on the front wheels.
» Check and correct the seating of the snow chains after driving a few feet, if necessary. Follow the instructions from the manufacturer.
» Note the maximum speed of 30 mph (50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain rim/tire combinations due to technical reasons. Check with an authorized Audi dealer or authorized Audi Service Facility to see if you may use snow chains.
Use fine-mesh snow chains. They must not add more than 0.40 inch (10.5 mm) in height, including the chain lock. You must remove the snow chains on roads without snow. Otherwise, you could impair driving ability and damage the tires.
Using incorrect snow chains or installing snow chains incorrectly can result in loss of vehicle control, which increases the risk of an accident.
‘Snow chains can damage the rims and wheel covers* if the chains come into direct contact with them. Remove the wheel covers first. Use coated snow chains.
When using snow chains, it may be advisable to limit the ESC = page 107.
Low-profile tires 3s to: vehicles with low-profile tires
Compared to other tire/rim combinations, lowprofile tires offer a wider tread surface and a larger rim diameter with shorter tire sidewalls. This results in an agile driving style. However, it may reduce the level of comfort and increase road noise when driving on roads in poor condition. Low-profile tires can become damaged more quickly than standard tires when driving over large bumps, potholes, manhole covers, and
Wheels
curbs. Therefore, it is particularly important to maintain the correct tire pressure page 242. To reduce the risk of damage to the tires and rims, drive very carefully on poor roads. Check your wheels regularly every 2,000 mi (3,000 km) for damage. For example, check for bulges/cracks on the tires or deformations/ cracks on the rims. After a heavy impact or damage, have the tires and rims inspected or replaced immediately by an authorized Audi dealer or authorized Audi Service Facility. Low-profile tires can wear out faster than standard tires.
Uniform tire quality grading —Tread wear —Traction AA ABC Temperature A BC Quality grades can be found where applicable on the tire side wall between tread shoulder and maximum section width page 232, fig. 142. For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Requirements in addition to these grades. Tread wear
The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course.
For example, a tire graded 150 would wear one and one half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to. variations in driving habits, service practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance oA. Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure > A\. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cor nering, hydroplaning or peak traction characteristics.
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
Temperature grades apply to tires that are properly inflated and not over or underinflated.
Wheels
Tire pressure monitoring system ( General notes
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telitale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

The tire pressure indicator in the instrument cluster informs you if the tire pressure is too low or if there is a system malfunction. Using the ABS sensors, the tire pressure monitoring system compares the tire tread circumference and vibration characteristics of the individual tires. If the pressure changes in one or more tires, this is indicated in the instrument cluster display with an indicator light BJ and a message. If only one tire is affected, the location of that tire will be indicated. The tire pressures must be stored again each time you change the pressures (switching between partial and full load pressure) or after changing or replacing a tire on your vehicle = page 250. The tire pressure monitoring system only monitors the tire pressure you have stored. Refer to the tire pressure label for the recommended tire pressure for your vehicle page 242, fig. 145. Tire tread circumference and vibration characteristics can change and cause a tire pressure warning if: — The tire pressure in one or more tires is too low ~The tires have structural damage = The tire was replaced or the tire pressure was changed and it was not stored page 250

If the indicator light does turn off or turns on again after a short period of time, drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.
~If the tire pressure indicator appears in the display, reduce your speed immediately and avoid any hard steering or braking maneuvers. Stop as soon as possible and check the tires and their pressure.
~The driver is responsible for maintaining the correct tire pressure. You must check the tire pressure regularly.
— Under certain conditions (such as a sporty driving style, winter conditions, or unpaved roads), the tire pressure monitoring system indicator may be delayed.
The tire pressure monitoring system can also stop working when there is an ESC malfunction.

Tire pressure monitoring system () General notes
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.
Wheels
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
General information Applies to: vehicles with tire pressure monitoring system The tire pressure monitoring system monitors the pressure in the four tires when driving.
The system uses sensors that measure the temperature and pressure in the tires. The data is sent from these sensors to the control module by radio frequency. The tire pressure monitoring system shows the current pressures and temperatures of the tires in the MMI while driving page 252. It also compares the current tire pressures with the stored tire pressures and gives a warning in the driver information system if the tire pressure is different from what is stored page 252.
The system does not detect if the stored tire pressures match the recommended tire pressures. You must store the tire pressures again in each of the following situations * page 252: ~Each time the tire pressures change, for example when the load in the vehicle changes ~After replacing a tire — If wheels with new wheel sensors are used
~The tire pressure monitoring system assists the driver in monitoring tire pressures. The driver is responsible for having the tires inflated to the correct pressure.
— Do not change the tire pressure when the temperature of the tire is extremely high. This could result in serious damage to the tire and even cause the tire to burst, increasing the risk of an accident.
— Atire with low pressure flexes more. This heats the tire up too much. This could cause the tread to separate and even cause the tire to burst, increasing the risk of an accident.
~The tire pressure monitoring system does not warn about damage or defects in the tire construction that could cause the tire to burst, for example. Inspect your tires regularly.
— If tires are replaced, the sensors and valves do not need to be removed or replaced. Only replace the valve stem and, if necessary, the valve and the wheel electronics. If you have questions, see an authorized Audi dealer or authorized Audi Service Facility.
— An incorrect display or a malfunction in the tire pressure monitoring system can occur after using the tire mobility kit*. Have the sensors replaced by an authorized Audi dealer or authorized Audi Service Facility.
~The system complies with United States FCC regulations and ISED regulations > page 288.

Displaying tire pressures and temperatures Applies to: vehicles with tire pressure monitoring system Requirement: you must be driving the vehicle. > Applies to MMI: Select on the home screen: VEHICLE > Settings & Service > Tire pressure monitoring > Display tire pressure.
The current tire pressures are shown in green, yellow, or red numbers: ~ Green: the current tire pressure and the specified tire pressure are approximately the same. ~ Yellow: the current tire pressure is lower than
the specified tire pressure. ~ Red: the current tire pressure is much lower
than the specified tire pressure.
The specified tire pressure is the last tire pressure that was stored * page 252. Note that the tire pressure also depends on the temperature of the tire. The tire pressure increases as the tires become warmer while driving.
Read and follow the important information and notes > page 257.
The tire pressure or temperature is not displayed while the vehicle is stationary and in adaptation mode. Dashes --.-- are shown in place of the pressure and temperature.

If the indicator light turns on and the message appears, the tire pressure has reached a critical level compared to the specified pressure. Avoid unnecessary steering and braking maneuvers.
Adapt your driving style to the situation. Stop as soon as possible and check the tire(s). If it is possible to continue driving, see an authorized Audi dealer or authorized Audi Service Facility immediately and have your tire(s) repaired or replaced if necessary.
Read and follow the important information and notes > page 257.
Storing new tire pressures Applies to: vehicles with tire pressure monitoring system The tire pressure specifications must be stored correctly for the tire pressure monitoring system to function reliably. It is always necessary to store the tire pressures when the tire pressures are modified, for example due to a change in load or when new sensors are installed.
» Before storing the tire pressures, make sure the tire pressures of all four tires meet the specified values and are adapted to the load => page 242, fig. 145. Only correct and store the pressure in tires whose temperature is approximately the same as the ambient temperature. If the temperature of the tire is higher than the ambient air temperature, the tire Pressure must be increased approximately 3 PSI (0,2 bar) above the value on the sticker.
» Switch the ignition on.
» Applies to MMI: Select on the home screen: VEHICLE > Settings & Service > Tire pressure monitoring > Store tire pressure > Yes, store now.
» If the changed tire pressures are not displayed on the MMI, drive the vehicle for approximately 10 minutes so that the sensor signal from the wheels is received again.
During this adaptation phase, --.-- is displayed for the pressure and temperature and the tire pressure monitoring system is only partially available. It only provides a warning if one or more tire pressures is below the minimum permitted specified pressure.
Wheels
[Tire pressure: wheel change detected. Please check all tires and store pressures in MMI
If the indicator light turns on and the message appears, the system has detected that the location of the sensors has changed due to a wheel replacement, or new sensors have been installed. Store the new tire pressures.

If you cannot correct the malfunction and the [JJM indicator light stays on, drive immediately to an authorized Audi dealer or authorized Audi Service Facility to have the malfunction repaired.
Run-flat tires Applies to: vehicles with run-flat tires Run-flat tires can allow you to remain driving when there is a loss of pressure. Run-flat tires have reinforced sidewalls that protect the tire if there is a loss of pressure.
If the tire pressure monitoring system indicates a loss of pressure in one or several tires, you can continue driving on run-flat tires for at least 20 mi (30 km). Drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the problem corrected. Continuing to drive on run-flat tires is no longer possible if: ~ There is visible damage to the tires, such as
cracks in the sidewalls — Strong vibrations are felt while driving, or the
tire begins to smoke due to a strong build-up of heat
~The tire has been heavily damaged, for example in an accident. There is a risk that parts of the tire tread will detach and damage important vehicle components.
