2011 JEEP GRAND CHEROKEE light

It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted that could affect the airbag system. The diagnostics
also record the nature of the malfunction.
WARNING!
Ignoring the Airbag Warning Light 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 as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
airbag system immediately.
Driver And Passenger Advanced Front Airbag
Inflator Units
The Driver and Passenger Advanced Front Airbag Infla-
tor Units are located in the center of the steering wheel
and the right side of the instrument panel. When theORC detects a collision requiring the Advanced Front
Airbags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Advanced Front
Airbags. Different airbag inflation rates are possible,
based on the collision type and severity. The steering
wheel hub trim cover and the upper right side of the
instrument panel separate and fold out of the way as the
airbags inflate to their full size. The airbags fully inflate in
about 50 to 70 milliseconds. This is about half of the time
it takes to blink your eyes. The airbags then quickly
deflate while helping to restrain the driver and front
passenger.
The Advanced 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.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Because airbag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an airbag should have deployed.
NOTE:In a rollover the pretensioners, SAB and/or
SABIC airbags may deploy on both sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
If A Deployment Occurs
The Advanced Front Airbags are designed to deflate
immediately after deployment.
NOTE: Front and/or side airbags will not deploy in all
collisions. This does not mean something is wrong with
the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
78 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in a collision. The
Airbag Warning Light monitors the internal
circuits and interconnecting wiring associated
with airbag system electrical components. While the
airbag system is designed to be maintenance free, if any
of the following occurs, have an authorized dealer ser-
vice the airbag system immediately.
•The Airbag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to the ON/RUN position.
•The Airbag Warning Light remains on after the four to
eight-second interval.
•The Airbag Warning Light comes on intermittently or
remains on while driving. NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The airbags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper airbag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
•How various systems in your vehicle were operating;

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 81

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized 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. See your
authorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit the foot well of
your vehicle. Use only floor mats that leave the pedal
area unobstructed and that are firmly secured so that
they cannot slip out of position and interfere with the
pedals or impair safe operation of your vehicle in other
ways.
98 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including 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.
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.
