Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

POWER TILT/TELESCOPING STEERING
COLUMN — IF EQUIPPED
This feature allows you to tilt the steering column
upward or downward. It also allows you to lengthen or
shorten the steering column. The power tilt/telescoping
steering column lever is located below the multifunction
lever on the steering column.To tilt the steering column, move the lever up or down as
desired. To lengthen or shorten the steering column, pull
the lever toward you or push the lever away from you as
desired.
NOTE:For vehicles equipped with Driver Memory Seat,
you can use your Remote Keyless Entry (RKE) transmit-
ter or the memory switch on the driver’s door trim panel

programmed positions. Refer to “Driver Memory Seat”
in this section for further information.
WARNING!
Do not adjust the steering column while driving.
Adjusting the steering column while driving or driv-
ing with the steering column unlocked, could cause the
driver to lose control of the vehicle. Failure to follow
this warning may result in serious injury or death.

longerexists. Once driving conditions are safe, then pull
over and let vehicle idle. After 5 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 opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
EVIC Amber Telltale Lights
This area will show reconfigurable amber caution tell-
tales. These telltales include:
•Forward Collision Warning (FCW) OFF
This light warns the driver of a potential colli-
sion with the vehicle in front and prompts the
driver to take action in order to avoid the
collision. For further information, refer to

transmitter to recall one of two pre-programmed memory
profiles. Each memory profile contains desired position
settings for the driver seat, side mirror, adjustable pedals
(if equipped), power tilt and telescopic steering column
(if equipped), and a set of desired radio station presets.
When OFF is selected, only the MEMORY switch on the
driver’s door trim panel will recall memory profiles. To

STARTING AND OPERATING 435

•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
•
If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for impacted
material. Impacted material can cause a wheel imbalance
and freeing the wheels of it will correct the situation.
POWER STEERING
3.6L Engine
Your vehicle is equipped with an electro-hydraulic power
steering system that will give you good vehicle response
and increased ease of maneuverability in tight spaces.
5
STARTING AND OPERATING 487

The system will vary its assist to provide light efforts
while parking and good feel while driving. If the electro-
hydraulic power steering system experiences a fault that
prevents it from providing power steering assist, then the
system will provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the electri-
cally driven pump to reduce or stop power steering
assistance in order to prevent damage to the system.
Normal operation will resume once the system is
allowed to cool.
If the “SERVICE POWER STEERING SYSTEM”
message and a flashing icon are displayed on
the EVIC screen, it indicates that the vehicleneeds to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance. Refer to “Elec-
tronic Vehicle Information (EVIC)” in “Understanding
Your Instrument Panel” for further information.
If the “POWER STEERING SYSTEM OVER TEMP” mes-
sage and an icon are displayed on the EVIC screen, it
indicates that extreme steering maneuvers may have
occurred, which caused an over temperature condition in
the power steering system. You will lose power steering
assistance momentarily until the over temperature con-
dition no longer exists. Once driving conditions are safe,
then pull over and let vehicle idle for a few moments
until the light turns off. Refer to “Electronic Vehicle
Information (EVIC)” in “Understanding Your Instrument
Panel” for further information.
