Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can result
in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can cause
damage that result in tire failure.
• Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure. Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
•
Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable ride.

STARTING AND OPERATING 383
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
TIRE SERVICE KIT — IF EQUIPPED
Small punctures up to ¼” (6 mm) in the tire tread can be
sealed with Tire Service Kit. Foreign objects (e.g., screws or
nails) should not be removed from the tire. Tire Service Kit
can be used in outside temperatures down to approxi-
mately -4°F (-20°C).
This kit will provide a temporary tire seal, allowing you to
drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (90 km/h).

NOTE:•For vehicles so equipped, do not attempt to install a
center cap or wheel cover on the compact spare.
• Refer to “Compact Spare Tire” and to “Limited-Use
Spare” under “Tires—General Information” in “Start-
ing And Operating” for additional warnings, cautions,
and information about the spare tire, its use, and
operation.
10. Install the wheel bolts with the threaded end of the wheel bolt toward the wheel. Lightly tighten the wheel
bolts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not fully tighten the wheel bolts until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
11. Lower the vehicle to the ground by turning the jack handle counterclockwise.
12. Finish tightening the wheel bolts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern until each wheel bolt has been tightened twice. Refer to
“Torque Specifications” in this section for proper lug
bolt torque. If in doubt about the correct tightness, have
them checked with a torque wrench by your autho-
rized dealer or at a service station.
13. Lower the jack until it is free. Remove the wheel chocks. Reassemble the lug wrench to the jack assem-
bly and stow it in the spare tire area. Securely stow the
jack, tools, chocks and flat tire. Release the parking
brake before driving the vehicle.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire repaired
or replaced immediately.
Road Tire Installation
Vehicles Equipped With Wheel Covers
1. Mount the road tire on the axle.
2. To ease the installation process for steel wheels withwheel covers, install two wheel bolts on the wheel

which are on each side of the valve stem. Install the
wheel bolts with the threaded end of the bolt toward the
wheel. Lightly tighten the wheel bolts.
3. Align the valve notch in the wheel cover with the valve stem on the wheel. Install the cover by hand, snapping
the cover over the two wheel bolts. Do not use a
hammer or excessive force to install the cover. 4. Install the remaining wheel bolts and lightly tighten.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
serious injury.
5. Lower the vehicle to the ground by turning the jack handle counterclockwise.

them checked with a torque wrench by your authorized
dealer or service station.
7. Lower the jack until it is free. Remove the wheel chocks. Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided. Release the parking brake before
driving the vehicle.

JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump-
starting can be dangerous if done improperly so please
follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack follow
the manufacturer ’s operating instructions and precautions.
WARNING!
Do not attempt jump-starting if the battery is frozen. It
could rupture or explode and cause personal injury.
