Power Steering System Over Temp — If
Equipped
If the “POWER STEERING SYS-
TEM OVER TEMP” message and a
icon are displayed on the EVIC
screen, it indicates that extreme
steering maneuvers may have oc-
curred, which caused an over tem-
perature condition in the power steering sys-
tem. You will lose power steering assistance
momentarily until the over temperature condi-
tion no longer exists. Once driving conditions
are safe, then pull over and let vehicle idle.
After five minutes, the system will cool and
return to normal operation. Refer to “Power
Steering” in “Starting and Operating” for further
information.
NOTE:
• Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in

•Park Mode (Lowers the vehicle approxi-
mately 1.5 in (38 mm) – This position lowers
the vehicle for easier passenger entry and
exit as well as lowering the rear of the vehicle
for easier loading and unloading of cargo. To
enter Park Mode, press the “Down” button
once while the vehicle speed is below
25 mph (40 km/h). Once the vehicle speed
goes below 15 mph (24 km/h) the vehicle
height will begin to lower. If the vehicle
speed remains between 15 mph (24 km/h)
and 25 mph (40 km/h) for greater than
60 seconds, or the vehicle speed exceeds
25 mph (40 km/h) the Park Mode change will
be cancelled. To exit Park Mode, press the
“Up” button once while in Park Mode or drive
the vehicle over 15 mph (24 km/h).
The Selec-Terrain™ switch will automatically
change the vehicle to the proper height based
on the position of the Selec-Terrain™ switch.
The height can be changed from the default
Selec-Terrain™ setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain™”
in “Starting and Operating” for further informa-
tion. The system requires that the engine be running
for all changes. When lowering the vehicle all of
the doors, including the liftgate, must be
closed. If a door is opened at any time while the
vehicle is lowering the change will not be
completed until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses
a lifting and lowering pattern which keeps the
headlights from incorrectly shining into oncom-
ing traffic. When raising the vehicle, the rear of
the vehicle will move up first and then the front.
When lowering the vehicle, the front will move
down first and then the rear.
After the engine is turned off, it may be noticed
that the air suspension system operates briefly,
this is normal. The system is correcting the
position of the vehicle to ensure a proper
appearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture which allows the automatic leveling to be
disabled. Press and hold both the “Up” and
“Down” buttons simultaneously between 5 and
10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediatelyafter both buttons have been released. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information. Driving the vehicle over
5 mph (8 km/h) will return the air suspension to
normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for
further information.
WARNING!
The air suspension system uses a high pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.

JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid the danger
of being hit when operating the jack or
changing the wheel.
• Being under a jacked-up vehicle is danger-
ous. The vehicle could slip off the jack and
fall on you. You could be crushed. Never
put any part of your body under a vehicle
that is on a jack. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should not
be used to lift the vehicle for service pur-
poses. The vehicle should be jacked on a
firm level surface only. Avoid ice or slippery
areas.
Jack LocationThe scissor-type jack and tire changing tools
are located in rear cargo area, below the load
floor.
Spare Tire StowageThe spare tire is stowed under the load floor in
the rear cargo area and is secured to the body
with a special wing nut.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of
the vehicle closest to moving traffic, pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn the ignition OFF. 6. Block both the front
and rear of the wheel
diagonally opposite of
the jacking position. For
example, if changing
the right front tire, block
the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.

6. 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!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
7. Remove the lug nuts and wheel. 8. Position the spare wheel/tire on the vehicle
and install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the nuts.
CAUTION!
Be sure to mount the spare tire with the valve
stem facing outward. The vehicle could be
damaged if the spare tire is mounted incor-
rectly.
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 by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
10. 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 each nut has been tightened
twice. The correct wheel nut tightness 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 at a ser-
vice station.
11. Lower the jack to the fully closed position
and return it and the tools to the proper posi-
tions in the foam tray.
12. Remove the small center cap and securely
store the road wheel in the cargo area.
