2012 JEEP GRAND CHEROKEE light

Enhanced Seat Belt Use Reminder
System (BeltAlert)
BeltAlertis a feature intended to remind the
driver and front passenger (if equipped with
front passenger BeltAlert) to fasten their seat
belts. The feature is active whenever the igni-
tion is on. If the driver or front seat passenger is
unbelted, the Seat Belt Reminder Light will turn
on and remain on until both front seat belts are
fastened.
The BeltAlert warning sequence begins after
the vehicle speed is over 5 mph (8 km/h), by
blinking the Seat Belt Reminder Light and
sounding an intermittent chime. Once the se-
quence starts, it will continue for the entire
duration or until the respective seatbelts are
fastened. After the sequence completes, the
Seat Belt Reminder Light remains illuminated
until the respective seat belts are fastened. The
driver should instruct all other occupants to
fasten their seat belts. If a front seat belt is
unbuckled while traveling at speeds greater
than 5 mph (8 km/h), BeltAlert will provide
both audio and visual notification. The front passenger seat BeltAlert
is not ac-
tive when the front passenger seat is unoccu-
pied. BeltAlert may be triggered when an
animal or heavy object is on the front passen-
ger seat or when the seat is folded flat (if
equipped). It is recommended that pets be
restrained in the rear seat in pet harnesses or
pet carriers that are secured by seat belts, and
cargo is properly stowed.
BeltAlert can be enabled or disabled by your
authorized dealer. Chrysler Group LLC does
not recommend deactivating BeltAlert .
NOTE:
Although BeltAlert has been deactivated,
the Seat Belt Reminder Light will continue to
illuminate while the driver’s or front passen-
ger (if equipped with belt alert) seat belt
remains unfastened.
Seat Belt Lock OutThe center rear seat belt system has a lock out
feature that will not allow you to extract the
center webbing unless the rear seat upper
latch is engaged.
Seat Belts And Pregnant WomenWe recommend that pregnant women use the
seat belts throughout their pregnancy. Keeping
the mother safe is the best way to keep the
baby safe.
Pregnant women should wear the lap part of
the belt across the thighs and as snug across
the hips as possible. Keep the belt low so that
it does not come across the abdomen. That
way the strong bones of the hips will take the
force if there is an accident.
Supplemental Restraint System
(SRS) — Air Bags
This vehicle has Advanced Front Air Bags for
both the driver and front passenger as a
supplement to the seat belt restraint systems.
The driver’s Advanced Front Air Bag is
mounted in the center of the steering wheel.
The passenger’s Advanced Front Air Bag is
mounted in the instrument panel, above the
37

glove compartment. The words SRS AIRBAG
are embossed on the air bag covers. In addi-
tion, the vehicle is equipped with a Supplemen-
tal Driver Side Knee Air Bag mounted in the
instrument panel below the steering column.
The Advanced Front Air Bags have a multi-
stage inflator design. This allows the air bag to
have different rates of inflation based on the
severity and type of collision.This vehicle is equipped with Supplemental
Side Air Bag Inflatable Curtains (SABIC) to
protect the driver, front, and rear passengers
sitting next to a window. The SABIC air bags,
are located above the side windows and their
covers are also labeled: SRS AIRBAG.
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SAB) to provide
enhanced protection for an occupant during a
side impact. The Supplemental Seat-Mounted
Side Air Bags are located in the outboard side
of the front seats.
NOTE:
•
Air Bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any accident, the vehicle should be
taken to an authorized dealer immedi-
ately.

system provides output appropriate to the se-
verity and type of collision as determined by
the Occupant Restraint Controller (ORC), which
may receive information from the front impact
sensors.

The first stage inflator is triggered immediately
during an impact that requires air bag deploy-
ment. This low output is used in less severe
collisions. A higher energy output is used for
more severe collisions.
WARNING!
•No objects should be placed over or near
the air bag on the instrument panel, be-
cause any such objects could cause harm if
the vehicle is in a collision severe enough
to cause the air bag to inflate.
• Do not put anything on or around the air
bag covers or attempt to open them manu-
ally. You may damage the air bags and you
could be injured because the air bags may
no longer be functional. The protective cov-
ers for the air bag cushions are designed to
open only when the air bags are inflating.
• Do not drill, cut or tamper with the knee
bolster in any way.
• Do not mount any accessories to the knee
bolster such as alarm lights, stereos, citi-
zen band radios, etc. Supplemental Seat-Mounted Side Air Bags
(SAB)
Supplemental Seat-Mounted Side Air Bags
(SAB) may provide enhanced protection to
help protect an occupant during a side impact.
The SAB is marked with an air bag label sewn
into the outboard side of the front seats.
When the air bag deploys, it opens the seam
between the front and side of the seat’s trim
cover. Each air bag deploys independently; a
left side impact deploys the left air bag only
and a right-side impact deploys the right air
bag only. Supplemental Side Air Bag Inflatable
Curtain (SABIC)
SABIC air bags may offer side-impact and
vehicle rollover protection to front and rear seat
outboard occupants in addition to that pro-
vided by the body structure. Each air bag
features inflated chambers placed adjacent to
the head of each outboard occupant that re-
duce the potential for side-impact head inju-
ries. The SABIC deploy downward, covering
both windows on the impact side.

Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Air Bags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact.
Advanced Front Air Bags and Supplemental
Driver Side Knee Air Bag are designed to
provide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on the severity and type of collision.
Advanced Front Air Bags are not expected to
reduce the risk of injury in rear, or side colli-
sions.
The Advanced Front Air Bags and Supplemen-
tal Driver Side Knee Air Bag will not deploy in all
frontal collisions, including some that may pro-
duce substantial vehicle damage — for ex-
ample, some pole collisions, truck underrides,
and angle offset collisions. On the other hand,
depending on the type and location of impact,
Advanced Front Air Bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
The side air bags will not deploy in all side
collisions. Side air bag deployment will depend
on the severity and type of collision.Because air bag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating air bag.
The ORC monitors the readiness of the elec-
tronic parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, the air
bag system is not on and the air bags will not
inflate.
The ORC contains a backup power supply
system that may deploy the air bags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, the ORC turns on the Air Bag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Air Bag Warning Light if a
malfunction is noted that could affect the air
bag system. The diagnostics also record the
nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bags 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
air bag system immediately.

especially applies to children. The side curtain
air bag 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, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events.
Enhanced Accident Response System
In the event of an impact causing air bag
deployment, if the communication network re-
mains 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 Air Bags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean some-
thing is wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
• The nylon air bag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger as the air
bags deploy and unfold. The abrasions are
similar to friction rope burns or those you
might get sliding along a carpet or gymna-
sium floor. They are not caused by contact
with chemicals. They are not permanent and normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a nor-
mal by-product of the process that gener-
ates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area with
cool water. For nose or throat irritation, move
to fresh air. If the irritation continues, see your
doctor. If these particles settle on your cloth-
ing, follow the garment manufacturer’s in-
structions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another colli-
sion, the air bags will not be in place to protect
you.

WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have
the air bags, seat belt pretensioners, and the
front seat belt retractor assemblies replaced
by an authorized dealer immediately. Also,
have the Occupant Restraint Controller
(ORC) system serviced as well.
Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag 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, vehicle body structure, or add
aftermarket side steps or running boards.
(Continued)
WARNING! (Continued)
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to tell
anyone who works on your vehicle that it
has an air bag system.
• 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 including your
trim cover and cushion needs to be ser-
viced 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 authorized
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 associ-
ated with air bag system electrical
components. While the air bag system is de-
signed 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 inter-
mittently or remains on while driving.

WARNING!
•Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
• It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing (CO), follow these safety tips: Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate
open, make sure that all windows are closed
and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation
mode.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or misposi-
tioned 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 disas-
semble 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 authorized dealer.

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 exte-
rior 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 lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing 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.
