ROLLOVER WARNING
Utility vehicles have a significantly higher
rollover rate than other types of vehicles. This
vehicle has a higher ground clearance and a
higher center of gravity than many passenger
vehicles. It is capable of performing better ina wide variety of off-road applications. Driven
in an unsafe manner, all vehicles can go out
of control. Because of the higher center of
gravity, if this vehicle is out of control it may
roll over when some other vehicles may not.
Do not attempt sharp turns, abrupt maneu-
vers, or other unsafe driving actions that can
cause loss of vehicle control. Failure to oper-
ate this vehicle safely may result in a colli-
sion, rollover of the vehicle, and severe or
fatal injury. Drive carefully.
Failure to use the driver and passenger seat
belts provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted
person is significantly more likely to die than
a person wearing a seat belt. Always buckle
up.

hicle until you are sure the jack is fully
engaged.
5. Raise the vehicle by turning the jack
screw clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire. Minimum tire lift provides
maximum stability.
WARNING!

Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sus-
tained speeds over 75 mph (120 km/h). For
speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire
dealer for recommended safe operating
speeds, loading and cold tire inflation pres-
sures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of non-
studded tires. Some states prohibit studded
tires; therefore, local laws should be checked
before using these tire types.
Spare Tires — If Equipped
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “In Case Of Emergency” in
the Owner’s Manual for further information.

Because of the reduced ground clearance,
do not take your vehicle through an auto-

Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare
tire and wheel equivalent in look and func-
tion to the original equipment tire and wheel
found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rota-
tion for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for
the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emer-
gency use only. You can identify if your ve-
hicle is equipped with a compact spare by
looking at the spare tire description on the
Tire and Loading Information Placard located
on the driver’s side door opening or on thesidewall of the tire. Compact spare tire de-
scriptions begin with the letter “T” or “S”
preceding the size designation. Example:
T145/80D18 103M.
T,S=Temporary Spare Tire
Since this tire has limited tread life, the
original equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity.
Do not install a wheel cover or attempt to
mount a conventional tire on the compact
spare wheel, since the wheel is designed
specifically for the compact spare tire. Do not
install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact and collapsible spares are for tem-
porary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have lim-
ited tread life. When the tread is worn to the
tread wear indicators, the temporary use
spare tire needs to be replaced. Be sure to
follow the warnings, which apply to your
