WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has window airbags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.
Airbag System Components
The airbag system consists of the following:
•Airbag Control Module
•AIRBAG Readiness Light
•Driver Airbag
•Passenger Airbag
•Steering Wheel and Column
•Instrument Panel
•Crash Sensor
•Interconnecting Wiring
•Knee Impact Bolsters
•Passenger Side Frontal Airbag ON/OFF Switch (Stan-

46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Window Airbag System, on vehicles equipped,
consists of the following:
•AIRBAG Readiness Light (shared with the front airbag
system)
•Window Bags Above the Side Windows.
•Airbag Control Module (shared with the front airbag
system)
•Side impact sensors
•Interconnecting Wiring
How The Airbag System Works
•
The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
•The airbag control module will not detect roll over, or
rear collisions.
•The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in theOffposition, in
the ACC position or not in the ignition, the airbags are
not on and will not inflate
•The airbag control module also turns on the AIR BAG
light in the instrument panel for 6 to 8 seconds when
the ignition is first turned on, then turns the light off.
•If it detects a malfunction in any part of the
system, it turns on the light either momen-
tarily or continuously. The instrument clus-
ter will flash the seat belt indicator if it
detects a fault with the airbag indicator.

Maintaining Your Airbag Systems
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 struc-
ture, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
Airbag Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system promptly:
•The airbag light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
•The light remains on or flickers after the 6 to 8 second
interval.
•The light flickers or comes on and remains on while
driving.
NOTE:If the speedometer, tachometer or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready

CARGO Light — If Equipped
The cargo lights are turned on by pressing on the
CARGO button. The interior lights will also turn on
when the cargo lights are on. The cargo lights will also
turn on for 30 seconds when a key fob Unlock is pressed,
as part of the illuminated entry feature.
MULTIFUNCTION CONTROL LEVER
The multifunction control lever is located on the left side
of the steering column.
Turn Signals
Move the lever up or down to signal a right-hand or
left-hand turn.
The arrow on either side of the instrument cluster flashes
to indicate the direction of the turn, and proper operation
of the front and rear turn signal lights. If a defective bulb
or wiring circuit is detected for the turn signal system, the
arrow indicators will flash at a faster rate. If an indicator
fails to light when the lever is moved, it would suggest
that the switch or indicator lamp is defective.
You can signal a lane change by moving the lever
partially up or down.

WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
