Checking and Filling
Fuel
Types of gasoline
The correct gasoline grade is stated on the inside of the fuel filler door.
The vehicle is equipped with a catalytic converter and must only be driven with unleaded gasoline. Audi recommends using TOP TIER Detergent Gasoline. For additional information on TOP TIER Detergent Gasoline, visit www.toptiergas.com.
The individual gasoline grades are differentiated by octane ratings. This value is given with (R#M)/2 equating to AKI or in RON. The headings below match the sticker in the fuel filler door (examples): UNLEADED FUEL ONLY MIN. (R+M)/2 87 Regular / MIN. RON 91 Regular
Use regular gasoline with minimum 87 AKI / 91 RON 2@. Audi recommends using premium gasoline with minimum 91 AKI / 95 RON to achieve the rated horsepower and torque. UNLEADED FUEL ONLY PREMIUM MIN. (R+M)/2 91 / SUPER MIN. RON 95
Using premium gasoline with minimum 91 AKI / 95 RON is recommended. If premium gasoline is not available, you can also use regular gasoline 87 AKI / 91 RON. However this does reduce the engine power slightly. UNLEADED FUEL ONLY PREMIUM MIN. (R+M)/2 93 / SUPER PLUS MIN. RON 98 Using premium plus gasoline with at least 93 AKI / 98 RON is recommended.
If no premium plus gasoline is available, you can also use premium gasoline with 91 AKI/ 95 RON. However this does reduce the engine power slightly.
Filling the tank just one time with leaded fuel or other metallic additives will cause permanent deterioration to the catalytic converter function.
—When gasoline with an octane rating that is too low is used, high speeds or heavy engine load can lead to engine damage.
The vehicle may be filled with fuel that has a higher octane rating than what is required by the engine.
Gasoline mixture
Gasoline with alcohol (ethanol) You can fuel your vehicle with unleaded gasoline that has an ethanol content of up to 15%, for example “E15”. Gasoline adapted to the season Many gasoline fuels are adapted to the seasons. When the season changes, refueling at high-traffic gas stations is recommended. It is more likely that the gasoline will be suitable for the season there.
— Do not use gasoline that does not meet the specifications.
~Ethanol fuels with a high ethanol percentage, such as E30 - £100, must not be used. The fuel system will be damaged!
Methanol fuels with a high methanol percentage, such as M5 - M100, must not be used. The fuel system and the engine will be damaged!
~ Ifyou are unable to find out if a specific gasoline mixture meets the specifications, ask the gas station operator or their fuel supplier.
—Do not use any gasoline mixture whose composition cannot be identified.
— Audi does not assume any responsibility for damage to the fuel system or for performance problems caused by using gasoline
Checking and Filling
mixtures different from those specified. This type of damage also does not fall under the New Vehicle Limited Warranty or under the emissions control system warranty.
= If you notice a higher fuel consumption or poor handling or performance problems due to such gasoline mixtures, Audi recommends fueling with unblended gasoline.
Gasoline additives
An important issue for many automobile manufacturers is combustion residue in the engine that results from the use of certain fuels.
Although types of gasoline differ depending on the manufacturer, there are similarities. Certain substances in the gasoline may cause deposits in the engine. Additives in the gasoline that should keep the engine and fuel system clean do not all function equally. Audi recommends using TOP TIER Detergent Gasoline. For additional information on TOP TIER Detergent Gasoline, visit www.toptiergas.com. If you use incorrect fuels over a long period of time, the maximum engine performance may be impaired by combustion residue.
Damage or malfunctions caused by the use of incorrect types of gasoline are not covered by the New Vehicle Limited Warranty.
= Only gasoline additives that have been approved by Audi may be used.
Refueling Messages
The following messages may appear depending on the vehicle equipment: Messages If the [EM] indicator light appears with a corresponding message, refuel the vehicle. Bil tank system: malfunction! Please contact Service

» Turn the fuel cap clockwise until it clicks into place.
» Close the fuel filler door and then press on the left side until it latches.
The correct fuel type for your vehicle can be found on a label located on the inside of the fuel filler door. For additional information on fuel, see page 211. For the tank capacity in your vehicle, refer to the Technical Data > page 287. To reduce the risk of fuel leaking out or vapors escaping, make sure that the fuel tank is closed correctly. Otherwise the [J indicator light will turnon.
Improper fueling procedures and improper handling of fuel can lead to explosions, fires, severe burns, and other injuries. —Do not smoke. Keep away from open flames. ~The ignition must be switched off when refueling. —Mobile devices, radio devices, and other radio equipment should always be switched off when refueling. Electromagnetic rays could cause sparks and start a fire.
= If you do not insert the fuel pump nozzle all the way into the filler tube, then fuel can leak out. Spilled fuel can ignite and start a fire.
—Never get into the vehicle when refueling. If there is an exceptional situation where you must enter the vehicle, close the door and touch a metal surface before touching the fuel pump nozzle again. This will reduce the risk of electrostatic discharge that can cause flying sparks. Sparks can start a fire when refueling.
1) Depending on the engine and country
Audi does not recommend transporting fuel, containers inside the vehicle. Fuel could leak out of the container and ignite, especially during an accident. This can cause explosions, fires, and injuries. — If you must transport fuel in a fuel container, note the following:
— Always place the fuel container on the ground before filling. Never fill the fuel container with fuel whil is inside or on the vehicle. Electrostatic discharge can occur while refueling and the fuel vapors could ignite.
—When using fuel containers made of metal, the fuel pump nozzle must always remain in contact with the container to reduce the risk of static charge.
~ Insert the fuel pump nozzle as far as possible into the filler opening while refueling.
— Follow the applicable legal regulations in the country where you are driving when using, storing and transporting fuel containers.
— Make sure that the fuel container meets the industry standards, for example ANSI or ASTM F852-86.
— Remove fuel that has overflowed onto any vehicle components immediately to reduce the risk of damage to the vehicle.
—Never drive until the fuel tank is completely empty. The irregular supply of fuel that results from that can cause engine misfires. Uncombusted fuel may enter the exhaust system and increase the risk of damage to the catalytic converter.
—Do not overfill the fuel tank, or fuel could leak out when the vehicle is warming up.
~Fuel should never enter the sewer system or come into contact with the ground. >

Changing engine oil Audi recommends having the oil changed at an authorized Audi dealer or authorized Audi Service Facility.
Observe the safety precautions > page 214, General information.
The engine oil must be changed at the intervals specified in the Warranty & Maintenance Booklet. This is very important because the lubrication function of the oil gradually declines during regular vehicle operation. The engine oil should be changed more frequently under certain circumstances. Have the oil changed more frequently if you often drive short distances, your vehicle is predominantly in stopand-go traffic situations, is in very dusty environments, or is operated for long periods of time in temperatures below zero.
Cleansing additives in the oil make fresh oil appear darker after the engine has run briefly. This is normal and no reason to change the engine oil more frequently than recommended.
Because correctly disposing of engine oil is difficult and special tools and technical knowledge are needed for an oil change, Audi recommends having your engine oil changed by an authorized Audi dealer or authorized Audi Service Facility. If you change the engine oil yourself, please note the following important information:
If you change the engine oil on the vehicle yourself, the following precautions must be followed: — Wear protective eyewear. — Due to the risk of scalding, allow the engine
to cool down sufficiently. = Maintain enough distance when you are removing the oil drain plug. While doing this, keep your forearm parallel to the ground to reduce the risk of hot oil dripping down your arm.
— Drain the oil into a container designed for this purpose that is large enough to hold the full amount of oil in your engine.
— Engine oil is poisonous. Always store out of reach of children.
— Prolonged contact of used engine oil with the skin may cause skin damage. Always wash oil off immediately with soap and water to protect your skin.
Do not mix any additives with the engine oil. Additives may cause engine damage that is not covered by your New Vehicle Limited Warranty.
— Before changing the engine oil, make sure you can dispose of the used engine oil correctly.
— Engine oil must always be disposed of correctly. Do not dump it in the yard, in the forest, or in open water, river channels, or sewers.
~ Have your used engine oil recycled by bringing it to a used oil collection site or contact a gas station.
