Enhanced Accident Response
If the airbags and seat belt pretensioners deploy after an
impact and the electrical system remains functional,
vehicles equipped with power door locks will unlock
automatically. In addition, approximately 10 seconds
after the vehicle has stopped moving, the interior lights
will illuminate until the ignition switch is turned off.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could
cause it to fail when you need it. You could be injured
because the airbags are not there to protect you. Do not
modify the components or wiring, including adding any
kind of badges or stickers to the steering wheel hub
trim cover or the upper right side of the instrument
panel. Do not modify the front bumper, vehicle body
structure, or frame.
•Do not attempt to modify any part of your advanced
airbag system. The airbag may inflate accidentally or
may not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
advanced airbag system service. If your seat including
your trim cover and cushion needs to be serviced in any
way (including removal or loosening/tightening of seat
attachment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accessories
may be used. If it is necessary to modify an advanced
airbag system for persons with disabilities, contact your
authorized dealer.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects lodged in the tread. Inspect tread and sidewall for cuts or
cracks. Check wheel nuts for tightness, and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
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 fuel, power steering fluid, trans-
mission fluid or brake fluid leaks are suspected, the cause
should be located and corrected immediately.
90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Vehicles and other objects seen in a passenger side
convex mirror will look smaller and farther away
than they really are. Relying too much on your
passenger side convex mirror could cause you to
collide with another vehicle or other object. Use your
inside mirror when judging the size or distance of a
vehicle seen in the passenger side convex mirror.
Some vehicles will not have a convex passenger side
mirror.
Exterior Mirrors Folding Feature
All exterior mirrors are hinged and may be moved either
forward or rearward to resist damage. The hinges have
three detent positions; full forward, full rearward, and
normal.
Power Folding Outside Mirrors — If Equipped
Turn the power mirror switch knob all the way down to
the left or right to fold in the mirrors. Turn the knob back
upward to the left mirror, right mirror, or off (center)
position to the normal (unfolded) driving position.
Both mirrors will always move together and will fold
anytime the knob is turned. The ignition switch does not
have to be in the ON position.
Power Remote-Control Mirrors — If Equipped
Use the mirror select switch, located on the instrument
panel to the left of the steering column, to adjust the view
obtained in the outside mirrors. Press the rocker switch to
the L or R for Left or Right mirror selection. Use the
center off position to guard against accidentally moving
a mirror position.
98 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE: The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

308 STARTING AND OPERATING

•There is a Traction Control System malfunction
•The system has been deactivated to prevent damage to
the brake system due to overheated brake tempera-
tures
NOTE: The Traction Control will make buzzing or
clicking sounds when in operation.
NOTE: Extended heavy use of Traction Control may
cause the system to deactivate and turn on the TRAC and
the OFF indicators located in the instrument cluster.
This is to prevent overheating of the brake system and is
a normal condition. The system will remain disabled for
about 4 minutes until the brakes have cooled. The system
will automatically reactivate and turn off the TRAC and
the OFF indicators.
If your vehicle becomes stuck in mud, ice, or snow, turn
the Traction Control System OFF before attempting to
“rock” the vehicle free.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE: Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
STARTING AND OPERATING 325

WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the
end of the steering wheel travel will increase the
steering fluid temperature and it should be avoided
when possible. Damage to the power steering pump
may occur.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is danger-
ous. Unequal traction can cause sudden pulling of
the front wheels. You could lose control of the
vehicle and possibly have an accident. Accelerate
slowly and carefully whenever there is likely to be
poor traction (ice, snow, wet mud, loose sand, etc.).

the black arrow on the bottom of the filter frame with the
direction of airflow (away from the blower motor and
towards the center of the car).
Refer to the “Maintenance Schedules” section of this
manual for the recommended air conditioning filter
replacement intervals.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership. 
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
The front suspension ball joints are permanently sealed.
No regular maintenance is required for these compo-
nents.
