WARNING: Utility vehicles have a significantly higher rollover rate than other types of vehicles.
WARNING: Vehicles with a higher center of gravity (utility and four-wheel drive vehicles) handle differently than vehicles with a lower center of gravity (passenger cars). Avoid sharp turns, excessive speed and abrupt steering in these vehicles. Failure to drive cautiously increases the risk of losing control of your vehicle, vehicle rollover, personal injury and death.
WARNING: In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seatbelt.
WARNING: Do not become overconfident in the ability of four-wheel drive vehicles. Although a four-wheel drive vehicle may accelerate better than a two-wheel drive vehicle in low traction situations, it won't stop any faster than two-wheel drive vehicles. Always drive at a safe speed.Utility vehicles and trucks handle differently than passenger cars in the various driving conditions that are encountered on streets, highways and
off-road. Utility vehicles and trucks are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions.
Study your owner's manual and any supplements for specific information about equipment features, instructions for safe driving and additional precautions to reduce the risk of an accident or serious injury.
A vehicle equipped with four-wheel drive (when selected) has the ability to use all four wheels to power itself. This increases traction which could enable you to safely drive over terrain and road conditions that a conventional two-wheel drive vehicle cannot.
On some four-wheel drive models, the initial shift from two-wheel drive to four-wheel drive while the vehicle is
moving can cause a momentary clunk and ratcheting sound. These sounds are normal as the front drivetrain comes up to speed and are not cause for concern.
Note: In four-wheel drive vehicles, the size of the spare tire relative to the remaining tires can have an effect on the 4x4 system's ability to engage and disengage.
On four-wheel drive vehicles, the size of the spare tire can affect the 4X4 system. If there is a significant difference between the size of the spare tire and the remaining tires, the four-wheel drive functionality will be limited.
When driving with the full-size dissimilar spare wheel and tire assembly, we recommend that you do not:
Exceed 50 mph (80 km/h) with 4WD mode turned on.
Turn on a 4WD mode unless the vehicle is stationary.
Use 4WD mode on dry pavement.
290
When driving with the full-size dissimilar spare wheel and tire assembly, 4WD functionality could be limited, especially when driving in a mechanically locked 4WD mode. You could experience the following:
Additional noise from the transfer case or other drive components.
Difficulty shifting out of a mechanically locked 4WD mode.
Use of a dissimilar spare wheel and tire assembly could lead to impairment of the following:
Comfort and noise.
Winter weather driving capability.
Wet driving capability.
Four-wheel drive capability.
Sport utility vehicles and trucks can differ from some other vehicles in a few noticeable ways. Your vehicle could be:
Higher - to allow higher load carrying capacity and to allow it to travel over rough terrain without damaging underbody components.
Shorter - to give it the capability to approach inclines and drive over the crest of a hill without damaging underbody components. All other things held equal, a shorter wheelbase could make your vehicle quicker to respond to steering inputs than a vehicle with a longer wheelbase.
Narrower - to provide greater maneuverability in tight spaces, particularly in off-road use.
As a result of the above dimensional differences, Sport utility vehicles and trucks often will have a higher center of gravity and a greater difference in center of gravity between the loaded and unloaded condition. These differences that make your vehicle so versatile also make it handle differently than an ordinary passenger car.

Glossary of Tire Terminology
*Tire label: A label showing the original equipment tire sizes, recommended inflation pressure and the maximum weight the vehicle can carry.
*Tire Identification Number (TIN): A number on the sidewall of each tire providing information about the tire brand and manufacturing plant, tire size and date of manufacture. Also referred to as DOT code.
*Inflation pressure: A measure of the amount of air in a tire.
*Standard load: A class of
P-Metric tires 35 psi (2.4 bar) and for Metric 36 psi (2.5 bar).
Increasing the inflation pressure beyond this pressure will not increase the tire’s load carrying capability.
*Extra load: A class of P-metric or Metric tires designed to carry a heavier maximum load at 42 psi (2.9 bar). Increasing the inflation pressure beyond this pressure will not increase the tire’s load carrying capability.
*kPa: Kilopascal, a metric unit of air pressure.
*PSI: Pounds per square inch, a standard unit of air pressure.
*Cold tire pressure: The tire pressure when the vehicle has been stationary and out of direct sunlight for an hour or more and prior to the vehicle being driven for 1 mile (1.6 kilometers).
*Recommended inflation pressure: The cold inflation pressure found on the Safety Compliance Certification Label (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver's seating position), or Tire Label located on the B-pillar or the edge of the driver's door.
293
*Bead area of the tire: Area of the tire next to the rim.
* Sidewall of the tire: Area between the bead area and the tread.
*Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
Information Contained on the Tire Sidewall
Both United States and Canada Federal regulations require tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides a U.S. DOT Tire Identification Number for safety standard certification and in case of a recall.

Location of the Tire Label
You will find a Tire Label containing tire inflation pressure by tire size and other important information located on the B-Pillar or the edge of the driver's door.
See Load Carrying (page 214).
Every day before you drive, check your tires. If one looks lower than the others, use a tire gauge to check pressure of all tires and adjust if required.
At least once a month and before long trips, inspect each tire and check the tire pressure with a tire gauge (including spare, if equipped). Inflate all tires to the inflation pressure recommended by us.
298
Use the recommended cold inflation pressure for optimum tire performance and wear.
Under-inflation or over-inflation could cause uneven treadwear patterns.
|
is WARNING: Under-inflation the most common cause of tire failures and may result in severe tire cracking, tread separation or blowout, with unexpected loss of vehicle control and increased risk of injury. Under-inflation increases sidewall flexing and rolling resistance, resulting in heat buildup and internal damage to the tire. It also may result in unnecessary tire stress, irregular wear, loss of vehicle control and accidents. A tire can lose up to half of its air pressure and not appear to be flat! |
Always inflate your tires to our recommended inflation pressure even if it is less than the maximum inflation pressure information found on the tire. Our recommended tire inflation pressure is found on the Safety Compliance Certification Label or
Tire Label (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver's seating position), or Tire Label located on the B-pillar or the edge of the driver's door.
Failure to follow the tire pressure recommendations can cause uneven treadwear patterns and adversely affect the way your vehicle handles.
Note: Do not reduce tire pressure to change the ride characteristics of the vehicle. If you do not maintain the inflation pressure at the levels specified by us, your vehicle could experience a condition known as shimmy.
Shimmy is a severe vibration and oscillation in the steering wheel after the vehicle travels over a bump or dip in the road that does not dampen out by itself. Shimmy could result from significant under-inflation of the tires, improper tires (load range, size, or
type), or vehicle modifications such as lift-kits. In the event that your vehicle experiences shimmy, you should slowly reduce speed by either lifting off the accelerator pedal or lightly applying the brakes. The shimmy will cease as the vehicle speed decreases.
Maximum Inflation Pressure is the tire manufacturer's maximum permissible pressure and the pressure at which the maximum load can be carried by the tire. This pressure is normally higher than
299
When weather temperature changes occur, tire inflation pressures also change. A 10°F (6°C) temperature drop can cause a corresponding drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures frequently and adjust them to the proper pressure which can be found on the Safety Compliance Certification Label or Tire Label.
To check the pressure in your tire(s):
Note: If you are checking tire pressure when the tire is hot, (for example, driven more than 1 mile [1.6 kilometers]), never bleed or reduce air pressure. The tires are hot from driving and it is normal for pressures to increase above recommended cold pressures. A hot tire at or below recommended cold inflation pressure could be significantly under-inflated.
Note: If you have to drive a distance to get air for your tire(s), check and record the tire pressure first and add the appropriate air pressure when you get to the pump. It is normal for tires to heat up and the air pressure inside to go up as you drive.
Note: If you overfill the tire, release air by pressing on the metal stem in the center of the valve. Then recheck the pressure with your tire gauge.
300
Note: Some spare tires operate at a higher inflation pressure than the other tires. For T type mini-spare tires, see the Dissimilar spare wheel and tire assembly information for a description. Store and maintain at 60 psi (4.15 bar). For full-size and dissimilar spare tires, see the Dissimilar spare wheel and tire assembly information for a description. Store and maintain at the higher of the front and rear inflation pressure as shown on the Safety Compliance Certification Label or Tire Label.
Inspecting Your Tires and Wheel Valve Stems
Periodically inspect the tire treads for uneven or excessive wear and remove objects such as stones, nails or glass that could be wedged in the tread grooves.
Check the tire and valve stems for holes, cracks, or cuts that could permit air leakage and repair or replace the tire and replace the valve stem. Inspect the tire sidewalls for cracking, cuts, bruises and other signs of damage or excessive wear. If internal damage to the tire is suspected, have the tire dismounted and
inspected in case it needs to be repaired or replaced. For your safety, tires that are damaged or show signs of excessive wear should not be used because they are more likely to blow out or fail.
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Inspect all your tires, including the spare, frequently, and replace them if one or more of the following conditions exist:
Tire Wear
E142546
301
Damage
Periodically inspect the tire treads and sidewalls for damage (such as bulges in the tread or sidewalls, cracks in the tread groove and separation in the tread or sidewall). If damage is observed or suspected have the tire inspected by a tire professional.
Tires can be damaged during off-road use, so inspection after off-road use is also recommended.
Age
|
repl WARNING: You should ou ace your spare tire when y replace the road tires or after six years due to aging even if it has not been used. |
U.S. DOT Tire Identification Number
Both United States and Canada Federal regulations require tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides a U.S. DOT Tire Identification Number for safety standard certification and in case of a recall.
This begins with the letters DOT and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code designating where it was manufactured, the next two are the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers 317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of 2001. The numbers in between are identification codes used for traceability. This information is used to contact customers if a tire defect requires a recall.

risk WARNING: To reduce the of serious injury, when mounting replacement tires and wheels, you should not exceed the maximum pressure indicated on the sidewall of the tire to set the beads without additional precautions listed below. If the beads do not seat at the maximum pressure indicated, re-lubricate and try again. the WARNING: When inflating tire for mounting pressures up to 20 psi (1.38 bar) greater than the maximum pressure on the tire sidewall, the following precautions must be taken to protect the person mounting the tire: |
Lubricate the tire bead and wheel bead seat area again.
|
steelWARNING: Always inflate carcass tires with a remote air fill with the person inflating standing at a minimum of 12 ft (3.66 m) away from the wheel and tire assembly. |
Important: Remember to replace the wheel valve stems when the road tires are replaced on your vehicle.
The two front tires or two rear tires should generally be replaced as a pair, except if the vehicle is equipped with four wheel drive. Vehicles equipped with four wheel drive should have all four tires replaced simultaneously.
Unevenly worn tires, mismatched makes, models or brands can be different in size, resulting in potential damage to the four wheel drive system.
The tire pressure sensors mounted in the wheels are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by us could affect the operation of your tire pressure monitoring system.
If the tire pressure monitoring system indicator is flashing, the system is malfunctioning. Your replacement tire might be incompatible with your tire pressure monitoring system, or some component of the system could be damaged.
Safety Practices
|
is s WARNING: If your vehicle tuck in snow, mud or sand, do not rapidly spin the tires; spinning the tires can tear the tire and cause an explosion. A tire can explode in as little as three to five seconds. whe WARNING: Do not spin the els at over 34 mph (55 km/h). The tires may fail and injure a passenger or bystander. |
Driving habits have a great deal to do with your tire mileage and safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on the road
*Do not run over curbs or hit the tire against a curb when parking
Highway Hazards
No matter how carefully you drive there is always the possibility that you could eventually have a flat tire on the highway. Drive slowly to the closest safe area out of traffic. This could further damage the flat tire, but your safety is more important.
304
under-inflated or damaged, deflate it, remove wheel and replace it with your spare tire and wheel. If you cannot detect a cause, have the vehicle towed to the nearest repair facility or tire dealer to have the vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole can cause the front end of your vehicle to become misaligned or cause damage to your tires. If your vehicle seems to pull to one side when you are driving, the wheels could be out of alignment. Have an authorized dealer check the wheel alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid treadwear of your tires and should be corrected by an authorized dealer. Front-wheel drive vehicles and those with an independent rear suspension could require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and wheel assembly could result in irregular tire wear.
Tire Rotation
|
sho WARNING: If the tire label ws different tire pressures for the front and rear tires and the vehicle has a tire pressure monitoring system, then you need to update the settings for the system sensors. Always perform the system reset procedure after tire rotation. If you do not reset the system, it may not provide a low tire pressure warning when necessary. |
Note: If your tires show uneven wear ask an authorized dealer to check for and correct any wheel misalignment, tire imbalance or mechanical problem involved before tire rotation.
Note: Your vehicle could be equipped with a dissimilar spare wheel and tire assembly. A dissimilar spare wheel and tire assembly is defined as a spare wheel and tire assembly that is different in brand, size or appearance from the road tires and wheels. If you have a dissimilar spare wheel and tire assembly it is intended for temporary use only and should not be used in a tire rotation.
Note: After having your tires rotated, inflation pressure must be checked and adjusted to the vehicle requirements.
305
Note: Uneven tread depth between the front and rear tires could lead to degradation in 4WD engagement and disengagement performance, additional noise from the 4WD system or damage.
Rotating your tires at the recommended interval (as indicated in the Scheduled Maintenance chapter) will help your tires wear more evenly, providing better tire performance and longer tire life.
Rear-wheel drive vehicles and four-wheel drive vehicles (front tires at left of diagram)
Sometimes irregular tire wear can be corrected by rotating the tires.
USING SNOW CHAINS
306
Note: The suspension insulation and bumpers help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains.
The tires on your vehicle have all-weather treads to provide traction in rain and snow. However, in some climates, you may need to use snow tires and snow chains. If you need to use snow chains, we recommend you use steel wheels of the same size and specifications, as snow chains may chip aluminum wheels.
Note: Only use snow chains on applicable tire sizes.
Only fit snow chains to the following specified tires:
255/70 R16 111T.
255/65 R17 110T.
265/65 R17 112T.
265/60 R18 110T.
LT265/65 R17 109T.
Only use S-Class snow chains, 0.6 in (15 mm) chain links.
Only use manual tensioning chains. Do not use self-tensioning chains.
Only use snow chains in pairs on the rear axle.
Note: The anti-lock brake system continues to operate normally.
Follow these guidelines when using snow tires and chains:
If possible, avoid fully loading your vehicle.
Install chains securely, verifying that the chains do not touch any wiring, brake lines, or fuel lines.
Drive cautiously. If you hear the chains rub or bang against your vehicle, stop and retighten the chains. If this does not work, remove the chains to prevent damage to your vehicle.
Remove the tire chains when you no longer need them. Do not use tire chains on dry roads.
If you have any questions regarding snow chains, please contact your authorized dealer.
When stability control is on, your vehicle may exhibit some unusual driving characteristics. To reduce this, switch traction control off. See Using Traction Control (page 174).

WARNING: The tire pressure monitoring system is not a substitute for manually checking tire pressures. You should periodically check tire pressures using a pressure gauge. Failure to correctly maintain tire pressures could increase the risk of tire failure, loss of control, vehicle rollover and personal injury.Note: You should only use tire sealants in roadside emergencies as they could cause damage to the tire pressure monitoring system sensor.
Note: If the tire pressure monitoring system sensor becomes damaged, it will not function.
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).
307
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 could 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 will not be able to detect or signal low tire pressure as intended. TPMS malfunctions could 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.
This device complies with Part 15 of the FCC Rules and with License exempt RSS Standards of Industry Canada. Operation is subject to the following two conditions:
Note: Changes or modifications not expressively approved by the party responsible for compliance could void the user's authority to operate the equipment. The term "IC:" before the radio certification number only signifies that Industry Canada technical specifications were met.
Note: Each road tire is equipped with a tire pressure sensor located inside the wheel and tire assembly cavity. The pressure sensor is attached to the valve stem. The pressure sensor is covered by the tire and is not visible unless the tire is removed. Take care when changing the tire to avoid damaging the sensor.
You should always have your tires serviced by an authorized dealer.
308
Check the tire pressure periodically (at least monthly) using an accurate tire gauge. See When Inflating Your Tires in this chapter.
The tire pressure monitoring system measures pressure in your road tires and sends the tire pressure readings to your vehicle. You can view the tire pressure readings through the information display. See General Information (page 96). The low tire pressure warning light will turn on if the tire pressure is significantly low. Once
the light is illuminated, your tires are under-inflated and need to be inflated to the manufacturer’s recommended tire pressure. Even if the light turns on and a short time later turns off, your tire pressure still needs to be checked.
When one of your road tires needs to be replaced with the temporary spare, the system will continue to identify an issue to remind you that the damaged road wheel and tire assembly needs to be repaired and put back on your vehicle.
To restore the full function of the tire pressure monitoring system, have the damaged road wheel and tire assembly repaired and remounted on your vehicle.
The main function of the tire pressure monitoring system is to warn you when your tires need air. It can also warn you in the event the system is no longer capable of functioning as intended. See the following chart for information concerning your tire pressure monitoring system:

When putting air into your tires (such as at a gas station or in your garage), the tire pressure monitoring system will not respond immediately to the air added to your tires.
It could take up to two minutes of driving over 20 mph (32 km/h) for the light to turn off after you have filled your tires to the recommended inflation pressure.
310
The tire pressure monitoring system monitors tire pressure in each pneumatic tire. While driving in a normal manner, a typical passenger tire inflation pressure could increase about 2–4 psi (14–28 kPa) from a cold start situation. If the vehicle is stationary overnight with the outside temperature significantly lower than the daytime temperature, the tire pressure could decrease about 3 psi (21 kPa) for a drop of 30°F (17°C) in ambient temperature. This lower pressure value could be detected by the tire pressure monitoring system as being significantly lower than the recommended inflation pressure and activate the system warning light for low tire pressure. If the low tire pressure warning light is on, visually check each tire to verify that no tire is flat. If one or more tires are flat, repair as necessary. Check the air pressure in the road tires. If any tire is under-inflated, carefully drive the vehicle to the nearest location where air can be added to the tires. Inflate all the tires to the recommended inflation pressure.
|
|
WARNING: If the tire pressure monitor sensor becomes damaged it may not function.Note: The use of tire sealant could damage your tire pressure monitoring system and should only be used in roadside emergencies.
Note: The tire pressure monitoring system indicator light illuminates when the spare tire is in use. To restore the full function of the monitoring system, all road wheels equipped with tire pressure monitoring sensors must be mounted on this vehicle.
If you get a flat tire when driving, do not heavily apply the brake. Instead, gradually decrease your speed. Firmly hold the steering wheel and slowly move to a safe place on the side of the road.
Have a flat serviced by an authorized dealer in order to prevent damage to the system sensors. See Tire Pressure Monitoring System (page 307). Replace the spare tire with a road tire as soon as possible. During repairing or replacing of the flat tire, have the authorized dealer inspect the system sensor for damage.

WARNING: Failure to follow these guidelines could result in an increased risk of loss of vehicle control, injury or death.If you have a dissimilar spare wheel and tire, then it is intended for temporary use only. This means that if you need to use it, you should replace it as soon as possible with a road wheel and tire assembly that is the same size and type as the road tires and wheels that were originally provided by Ford.
A dissimilar spare wheel and tire assembly is defined as a spare wheel and tire assembly that is different in brand, size or appearance from the road tires and wheels.
When driving with the full-size dissimilar spare wheel and tire assembly, do not:
Exceed 50 mph (80 km/h).
Use more than one dissimilar spare wheel and tire assembly at a time.
Use snow chains on the end of the vehicle with the dissimilar spare wheel and tire assembly.
311
When driving with the full-size dissimilar spare wheel and tire assembly, 4WD functionality may be limited, especially when driving in a mechanically locked 4WD mode. You may experience the following:
Additional noise from the transfer case or other drive components.
Difficulty shifting out of a mechanically locked 4WD mode.
When driving with the full-size dissimilar spare wheel and tire assembly you do not:
Exceed 50 mph (80 km/h) in 4WD.
Engage 4WD unless the vehicle is stationary.
Use 4WD on dry pavement.
The usage of a full-size dissimilar spare wheel and tire assembly can lead to impairment of the following:
Handling, stability and braking performance.
Comfort and noise.
Ground clearance and parking at curbs.
Winter weather driving capability.
Wet weather driving capability.
Four-wheel drive capability.
When driving with the full-size dissimilar spare wheel and tire assembly additional caution should be given to:
Towing a trailer.
Driving vehicles equipped with a camper body.
Driving vehicles with a load on the cargo rack.
Drive cautiously when using a full-size dissimilar spare wheel and tire assembly and seek service as soon as possible.
