JEEP GRAND CHEROKEE 2013 Owner handbook (in English)

Automatic Locking Retractor Mode
(ALR) — If Equipped
In this mode, the shoulder belt is automatically
pre-locked. The belt will still retract to remove
any slack in the shoulder belt. The Automatic
Locking Mode is available on all rear
passenger-seating positions with a combination
lap/shoulder belt. Use the Automatic Locking
Mode anytime a child safety seat is installed in
a seating position that has a belt with this
feature. Children 12 years old and under should
always be properly restrained in the rear seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts,
you will hear a clicking sound. This indicates the
safety belt is now in the Automatic Locking
Mode.How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt and
allow it to retract completely to disengage the
Automatic Locking Mode and activate the ve-
hicle sensitive (emergency) locking mode.
WARNING!
•
The belt and retractor assembly must be
replaced if the seat belt assembly Auto-
matic Locking Retractor (ALR) feature or
any other seat belt function is not working
properly when checked according to the
procedures in the Service Manual.
• Failure to replace the belt and retractor
assembly could increase the risk of injury
in collisions.
Energy Management FeatureThis vehicle has a safety belt system with an
Energy Management feature in the front seating
positions to help further reduce the risk of injury
in the event of a head-on collision. This safety belt system has a retractor assem-
bly that is designed to release webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the occu-
pant’s chest.
Seat Belt PretensionersThe seat belts for both front seating positions are
equipped with pretensioning devices that are de-
signed to remove slack from the seat belt in the
event of a collision. These devices may improve
the performance of the seat belt by assuring that
the belt is tight about the occupant early in a
collision. Pretensioners work for all size occu-
pants, including those in child restraints.
NOTE:
These devices are not a substitute for
proper seat belt placement by the occupant.
The seat belt still must be worn snugly and
positioned properly.
The pretensioners are triggered by the Occupant
Restraint Controller (ORC). Like the air bags, the
pretensioners are single use items. A deployed
pretensioner or a deployed air bag must be re-
placed immediately.

Supplemental Active Head
Restraints (AHR)
These head restraints are passive, deployable
components, and vehicles with this equipment
cannot be readily identified by any markings,
only through visual inspection of the head re-
straint. The head restraint will be split in two
halves, with the front half being soft foam and
trim, the back half being decorative plastic.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) de-
termines whether the severity, or type of rear
impact will require the Active Head Restraints
(AHR) to deploy. If a rear impact requires de-
ployment, both the driver and front passenger
seat AHRs will be deployed.
When AHRs deploy during a rear impact, the
front half of the head restraint extends forward
to minimize the gap between the back of the
occupant’s head and the AHR. This system is
designed to help prevent or reduce the extent of
injuries to the driver and front passenger in
certain types of rear impacts.NOTE:
The Active Head Restraints (AHR) may or
may not deploy in the event of a front or side
impact. However if during a front impact, a
secondary rear impact occurs, the AHR may
deploy based on the severity and type of the
impact.
CAUTION!
All occupants, including the driver, should
not operate a vehicle or sit in a vehicle’s seat
until the head restraints are placed in their
proper positions in order to minimize the risk
of neck injury in the event of a collision.
NOTE:
For more information on properly adjusting
and positioning the head restraint, refer to
“Adjusting Active Head Restraints” in “Un-
derstanding The Features Of Your Vehicle”.

Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered in a
collision, you must reset the head restraint on
the driver’s and front passenger seat. You can
recognize when the Active Head Restraint has
been triggered by the fact that they have moved
forward (as shown in step three of the resetting
procedure).
1. Grasp the deployed AHR from the rear seat.2. Position the hands on the top of the de-
ployed AHR at a comfortable position.
3. Pull
downthenrearward towards the rear of
the vehicle then downto engage the locking
mechanism.
4. The AHR front soft foam and trim half should
lock into the back decorative plastic half.

NOTE:
•If you have difficulties or problems reset-
ting the Active Head Restraints, see an
authorized dealer.
• For safety reasons, have the Active Head
Restraints checked by a qualified special-
ist at an authorized dealer.
Enhanced Seat Belt Use Reminder
System (BeltAlert®)
BeltAlert® is 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 passenger
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 BeltAlert®) 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 a collision.
Supplemental Restraint System
(SRS) — Air Bags
This vehicle has Advanced Front Air Bags for
both the driver and front passenger as a supple-
ment to the seat belt restraint systems. The
driver’s Advanced Front Air Bag is mounted in
the center of the steering wheel. The passen-
ger’s Advanced Front Air Bag is mounted in the
instrument panel, above the glove compart-
ment. The words SRS AIRBAG are embossed
on the air bag covers. In addition, the vehicle is
equipped with a Supplemental Driver Side Knee
Air Bag mounted in the instrument panel below
the steering column.The Advanced Front Air Bags have a multistage
inflator design. This allows the air bag to have
different rates of inflation based on several
factors, including the severity and type of colli-
sion.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.

Advanced Front Air Bag FeaturesThe Advanced Front Air Bag system has multi-
stage driver and front passenger air bags. This
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.
(Continued)
WARNING!(Continued)
•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
covers for the air bag cushions are de-
signed 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 ve-
hicle rollover protection to front and rear seat
outboard occupants in addition to that provided
by the body structure. Each air bag features
inflated chambers placed adjacent to the head
of each outboard occupant that reduce the
potential for side-impact head injuries. The
SABIC deploy downward, covering both win-
dows on the impact side.NOTE:
•
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.
• Should a vehicle rollover occur, the pre-
tensioners and/or SAB and SABIC air
bags on both sides of the vehicle may
deploy.
The system includes side impact sensors that
are calibrated to deploy the Supplemental Seat-
Mounted Side Air Bags and SABIC air bags
during impacts that require side air bag occu-
pant protection.

WARNING!
•Your vehicle is equipped with left and right
SABIC, do not stack luggage or other
cargo up high enough to block the location
of the SABIC. The area where the side
curtain air bag is located should remain
free from any obstructions.
• Do not use accessory seat covers or place
objects between you and the SAB; the
performance could be adversely affected
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. Always sit upright as possible with your back
against the seat back, use the seat belts prop-
erly, and use the appropriate sized child re-
straint, infant restraint or booster seat recom-
mended for the size and weight of the child.
SAB and SABIC air bags are a supplement to
the seat belt restraint system. Occupants, in-
cluding children who are up against or very
close to SAB or SABIC air bags can be seri-
ously injured or killed. Occupants, especially
children, should not lean on or sleep against the
door, side windows, or area where the SAB or
SABIC air bags inflate, even if they are in an
infant or child restraint.
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 driver and front passenger.
Side air bags also work with seat belts to
improve occupant protection.
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
Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Air Bags (SAB), and front seat
belt pretensioners, as required, depending on
several factors, including the severity and type
of impact.
44

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 several factors, including the sever-
ity and type of collision. Advanced Front Air
Bags are not expected to reduce the risk of
injury in rear, or side collisions.
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 decel-
eration over time, vehicle speed and damage bythemselves are not good indicators of whether or
not an air bag should have deployed.
Seat belts are necessary for your protection in
all collisions, 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 disconnected
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 quantity of
non-toxic gas is generated to inflate the Ad-
vanced Front Air Bags. Different air bag inflation
rates are possible, based on several factors,
including 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 air bags inflate to their
full size. The air bags fully inflate in about 50 to
70 milliseconds. 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 sig-
nals the inflator units. A large quantity of non-
toxic gas is generated to inflate the Supplemen-
tal 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 milliseconds.
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 exits through
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 especially
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 depend-
ing on the severity and type of collision. In these
events, the ORC will deploy the SABIC only on
the impact side of the vehicle.
