JEEP GRAND CHEROKEE 2012 Owner handbook (in English)

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.
Advanced Front Air Bag And Knee Bolster
Locations

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.

NOTE:
•Should a vehicle rollover occur, the pre-
tensioners and/or SAB and SABIC air
bags on both sides of the vehicle may
deploy.
• Air Bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• Being too close to the SAB and SABIC air
bags during deployment could cause you
to be severely injured or killed.
The system includes side impact sensors that
are calibrated to deploy the side air bags
during impacts that require air bag occupant
protection.WARNING!
• Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Cur-
tain (SABIC), do not stack luggage or other
cargo up high enough to block the location
of the SABIC. The area where the SABIC is
located should remain free from any ob-
structions.
• Do not use accessory seat covers or place
objects between you and the side air bags;
the performance could be adversely af-
fected and/or objects could be pushed into
you, causing serious injury.
• Your vehicle is equipped with SABIC air
bags, do not have any accessory items
installed which will alter the roof, including
adding a sunroof to your vehicle. Do not
add roof racks that require permanent at-
tachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof
of the vehicle for any reason. Supplemental Driver Side Knee Air Bag
The Supplemental Driver Side Knee Air Bag
provides enhanced protection and works to-
gether with the Driver Advanced Front Air Bag
during a frontal impact.
Knee Impact Bolster
The Knee Impact Bolster helps protect the
knees of the front passenger, and position the
front occupant for the best interaction with the
Advanced Front Air Bag.
Along with seat belts and pretensioners, Ad-
vanced Front Air Bags work with the Supple-
mental Driver Side Knee Air Bag and the pas-
senger side knee bolster to provide improved
protection for the front passenger. Side air bags
also work with seat belts to improve occupant
protection.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
Children 12 years old and under should always
ride buckled up in a rear seat.
40

WARNING!
Infants in rear-facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Air Bag. An air bag
deployment can cause severe injury or death
to infants in that position.
Children that are not big enough to wear the
vehicle seat belt properly (see Section on Child
Restraints) should be secured in the rear seat
in child restraints or belt-positioning booster
seats. Older children who do not use child
restraints or belt-positioning booster seats
should ride properly buckled up in the rear
seat. Never allow children to slide the shoulder
belt behind them or under their arm.
You should read the instructions provided with
your child restraint to make sure that you are
using it properly.
All occupants should always wear their lap and
shoulder belts properly.
The driver and front passenger seats should be
moved back as far as practical to allow the
Advanced Front Air Bags room to inflate. Do not lean against the door or window. If your
vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between you and the door.
If the air bag system in this vehicle needs to be
modified to accommodate a disabled person,
contact the Customer Center. Phone numbers
are provided under
If You Need Assistance.
WARNING!
•Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, the air
bags won’t deploy at all. Always wear your
seat belts even though you have air bags.
• Being too close to the steering wheel or
instrument panel during Advanced Front Air
Bag deployment could cause serious injury,
including death. Air Bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
(Continued)
WARNING!(Continued)
• The Supplemental Side Air Bag Inflatable
Curtain (SABIC) and Supplemental Seat-
Mounted Side Air Bag (SAB) also need
room to inflate. Do not lean against the
door or window. Sit upright in the center of
the seat.
• Being too close to the Supplemental Side
Air Bag Inflatable Curtain (SABIC) and/or
Seat-Mounted Side Air Bag (SAB) during
deployment could cause you to be severely
injured or killed.
Air Bag Deployment Sensors And
Controls
Occupant Restraint Controller (ORC)
The ORC is part of a regulated safety system
required for this vehicle.
The ORC determines if deployment of the front
and/or side air bags in a frontal or side collision
is required. Based on the impact sensor’s sig-
nals, a central electronic ORC deploys the
Advanced Front Air Bags, Supplemental Driver
Side Knee Air Bag, Supplemental Side Air Bag
41

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.

Driver And Passenger Advanced Front Air
Bag Inflator Units
The Driver and Passenger Advanced Front Air
Bag Inflator Units are located in the center of
the steering wheel and on the right side of the
instrument panel. When the ORC detects a
collision requiring the Advanced Front Air
Bags, it signals the inflator units. A large quan-
tity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag
inflation rates are possible, based on the colli-
sion 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 air bags inflate to their full size. The
air bags fully inflate in about 50 to 70 millisec-
onds. This is about half of the time it takes to
blink your eyes. The air bags then quickly
deflate while helping to restrain the driver and
front passenger.
The Advanced Front Air Bag gas is vented
through the vent holes in the sides of the air
bag. In this way, the air bags do not interfere
with your control of the vehicle.Supplemental Driver Side Knee Air Bag
Inflator Unit
The Supplemental Driver Side Knee Air Bag
unit is located in the instrument panel trim
beneath the steering column. When the ORC
detects a collision requiring the air bag, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the
Supplemental Driver Side Knee Air Bag. The
trim cover separates and folds out of the way
allowing the air bag to inflate to the full size. The
air bag fully inflates in about 15 to 20 millisec-
onds.
Supplemental Seat-Mounted Side Air Bag
(SAB) Inflator Units
The Supplemental Seat-Mounted Side Air Bags
are designed to activate only in certain side
collisions.
The ORC determines if a side collision requires
the side air bags to inflate, based on the
severity and type of collision.
Based on the severity and type of collision, the
side air bag inflator on the crash side of the
vehicle may be triggered, releasing a quantity
of non-toxic gas. The inflating SAB exitsthrough the seat seam into the space between
the occupant and the door. The SAB fully inflate
in about 10 milliseconds. The side air bag
moves at a very high speed and with such a
high force that it could injure you if you are not
seated properly, or if items are positioned in the
area where the side air bag inflates. This espe-
cially applies to children.
Supplemental Side Air Bag Inflatable
Curtain (SABIC) Inflator Units
During collisions where the impact is confined
to a particular area of the side of the vehicle,
the ORC may deploy the SABIC air bags,
depending on the severity and type of collision.
In these events, the ORC will deploy the SABIC
only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to
inflate the side curtain air bag. The inflating
side curtain air bag pushes the outside edge of
the headliner out of the way and covers the
window. The air bag inflates in about 30 milli-
seconds (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 side curtain air bag inflates. This
43

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.
44

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.
45

NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the
Occupant Restraint Controller (ORC) may
also be disabled. The air bags 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 air bag 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 orhitting 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;
• Whether or not the driver and passenger
safety belts were buckled/fastened;
• How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling. These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur.
NOTE:
EDR data are recorded by your vehicle only
if a non-trivial crash situation occurs; no
data are recorded by the EDR under normal
driving conditions and no personal data
(e.g., name, gender, age, and crash location)
are recorded. However, other parties, such
as law enforcement, could combine the EDR
data with the type of personally identifying
data routinely acquired during a crash in-
vestigation.
