2012 JEEP GRAND CHEROKEE light

A quantity of non-toxic gas is generated to inflate the
SABIC. The inflating SABIC pushes the outside edge of
the headliner out of the way and covers the window. The
SABIC inflates in about 30 milliseconds (about one-
quarter of the time that it takes to blink your eyes) with
enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:In a rollover the pretensioners and/or SAB and
SABIC air bags 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 air bag 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.

WARNING! (Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or
may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat, includ-
ing 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 the air bag system
for persons with disabilities, contact your autho-
rized dealer.
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free. If any of
the following occurs, have an authorized dealer service
the air bag system immediately.
•The Air Bag 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 Air Bag Warning Light remains on after the four to
eight-second interval.
•The Air Bag Warning Light comes on intermittently or
remains on while driving.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
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.
Air Bag 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 footwell 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.

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 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.
