ALL-WHEEL DRIVE (AWD) — IF EQUIPPED
This vehicle is equipped with an active on-demand
All-Wheel Drive (AWD) system which makes available
optimum traction for a wide variety of road surface and
driving conditions. The system minimizes wheel slip by
automatically redirecting torque to the front and rear
wheels as necessary.
To maximize fuel economy, your AWD vehicle automati-
cally defaults to rear-wheel drive (RWD) when road and
environmental conditions are such that wheel slip is
unlikely to occur. When specific road and environmental
conditions require increased levels of road traction, the
vehicle automatically shifts into AWD mode. Automatic
AWD operation could be activated by outside tempera-
ture, wheel slip, or other predetermined conditions (there
may be a slight delay for AWD engagement after a wheel
slip condition occurs). AWD can also be manually se-
lected by moving the shift lever into the AutoStickmode
(+/-) or activating the windshield wipers for an extendedperiod of time. Drive mode, RWD or AWD, is displayed
momentarily in the Electronic Vehicle Information Center
(EVIC) in the gage area of the vehicle display when the
transmission is first shifted into gear, and if the drive
mode changes during vehicle operation.
NOTE:If the “SERVICE AWD SYSTEM” warning mes-
sage appears after engine start up, or during driving, it
means that the AWD system is not functioning properly
and that service is required. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.

STARTING AND OPERATING 369

•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.
8. Install the lug nuts with the cone shaped end of the lug
nut toward the wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the wheel nuts fully until the vehicle
has been lowered. Failure to follow this warning may
result in personal injury.
9. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
10. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increasedleverage. Tighten the lug nuts in a star pattern until each
nut has been tightened twice. The correct tightness of
each lug nut is 110 ft/lb. (150 N·m). If in doubt about the
correct tightness, have them checked with a torque
wrench by your authorized dealer or at a service station.
11. Stow the jack, tools and flat tire. Make sure the base
of the jack faces the front of the vehicle before tightening
down the fastener.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.

WHAT TO DO IN EMERGENCIES 457

Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped
end of the nut toward the wheel. Lightly tighten the lug
nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the wheel nuts fully until the vehicle
has been lowered. Failure to follow this warning may
result in personal injury.
3. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until eachnut has been tightened twice. The correct tightness of
each lug nut is 110 ft/lbs (150 N·m). If in doubt about the
correct tightness, have them checked with a torque
wrench by your authorized dealer or service station.
5. After 25 miles (40 km) check the lug nut torque with a
torque wrench to ensure that all lug nuts are properly
seated against the wheel.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
