NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS
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.
WARNING: Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
• Avoid sharp turns and abrupt maneuvers;
• Drive at safe speeds for the conditions;
• Keep tires properly inflated;
• Never overload or improperly load your vehicle; and
• Make sure every passenger is properly restrained.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts and children/infants must use
appropriate restraints to minimize the risk of injury or ejection.
Study your owner’s guide 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.
VEHICLE CHARACTERISTICS
Four-wheel drive (4WD) system (if equipped)
A vehicle equipped with 4WD (when selected) has the ability to use all
four wheels to power itself. This increases traction which may enable you
to safely drive over terrain and road conditions that a conventional
two-wheel drive vehicle cannot.Tires, Wheels and Loading

Power is supplied to all four wheels through a transfer case or power
transfer unit. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in the Driving chapter. Information on transfer case
maintenance can be found in the Maintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
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 is not cause for concern.
WARNING: Do not become overconfident in the ability of 4WD
vehicles. Although a 4WD vehicle may accelerate better than
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.
How your vehicle differs from other vehicles
SUVs and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
• Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
• Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs than a vehicle with a longer
wheelbase. Tires, Wheels and Loading

Tire rotation
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 (RWD)
vehicles/Four-wheel drive (4WD)
vehicles (front tires at top of
diagram)
Sometimes irregular tire wear can be corrected by rotating the tires.
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 may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel 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.
WARNING: If the tire label shows different tire pressures for
the front and rear tires and the vehicle is equipped with TPMS
(tire pressure monitoring system), then the settings for the TPMS
sensors need to be updated. Always perform the TPMS reset procedure
after tire rotation. If the system is not reset, it may not provide a low
tire pressure warning when necessary. See the TPMS reset procedure
in this chapter. Tires, Wheels and Loading
