2008 JEEP GRAND CHEROKEE steering wheel

Driver And Front Passenger Supplemental
Restraint Systems (SRS)This vehicle has airbags for both the driver and right
front passenger as a supplement to the seat belt restraint
systems. The driver's front airbag is mounted in the
steering wheel. The passenger side airbag is mounted in
the instrument panel, above the glove compartment. The
words SRS/AIRBAG are embossed on the airbag covers.
NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.
The front airbags have a multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.

seat as far back as possible, and use the proper child
restraint. See ªChild Restraintº in this section.
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. All occupants should use their lap and shoulder belts
properly.
3. The driver and front passenger seats should be moved
back as far as practical to allow the front airbags room to
inflate.
4. Do not lean against the door or window, airbags will
inflate forcefully into the space between you and the
door.
5. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided under ªIf
You Need Assistanceº in Section 9 of this manual.WARNING!
²Relying 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.
²Being too close to the steering wheel or instrument
panel during airbag deployment could cause seri-
ous injury. Airbags need room to inflate. Sit back,
comfortably extending your arms to reach the
steering wheel or instrument panel.
²The left and right side curtain airbags need room
to inflate. Do not lean against the door or window.
Sit upright in the center of the seat.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag System Components
The airbag system consists of the following:
²Occupant Restraint Control Module
²Airbag Warning Light
²Driver Airbag
²Passenger Airbag
²Side Curtain Airbags above Side Windows
²Side Remote Acceleration Sensors
²Steering Wheel and Column
²Instrument Panel
²Interconnecting Wiring
²Knee Impact Bolsters
²Front Acceleration Sensors
²Driver and Front Passenger Seat Belt Pretensioner
How The Airbag System Works
²
TheOccupant Restraint Control (ORC) Modulede-
termines if a frontal, side, or rollover collision is severe
enough to require the front and/or side airbags to
inflate. The front airbag inflators are designed to
provide different rates of airbag inflation from direc-
tion provided by the ORC. The ORC will not detect
rear impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

Also, the ORC turns on the ªAirbag Warning
Lightº for 6 to 8 seconds for a self-check
when the ignition is first turned on. After the
self-check, the ªAirbag Warning Lightº will
turn off. If the ORC detects a malfunction in any part
of the system, it turns on the ªAirbag Warning Lightº
either momentarily or continuously. A single chime
will sound if the light comes on again after initial start
up.
WARNING!
Ignoring the ªAirbag Warning Lightº in your instru-
ment panel could mean you won't have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked right
away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50±70 milliseconds. This is
about half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag system is 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 or vehicle body
structure.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
²It 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 an airbag
system.
NOTE:Perchlorate Material ± special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate
Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
²The light does not come on during the 6 to 8 seconds
after the ignition switch is first turned on.
²The light remains on after the 6 to 8 second interval.
²The light comes on for any period of time while
driving.
