JEEP GRAND CHEROKEE 2013 WK2 / 4.G SRT Manual PDF

Seat Belt Extender
If a seat belt is too short, even when fully extended and
when the adjustable upper shoulder belt anchorage (if
equipped) is in its lowest position, your authorized
dealer can provide you with a seat belt extender. This
extender should be used only if the existing belt is not
long enough. When it is not required, remove the ex-
tender and store it.
WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.

70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 collision.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.
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 collision, the vehicle should be taken to an
authorized dealer immediately.

The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system provides
output appropriate to the severity 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 deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.
72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•No objects should be placed over or near the air bag
on the instrument panel, because 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 manually. 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
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, citizen 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 roll-
over 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 down-
ward, covering both windows on the impact side.

74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 pretensioners
and/or SAB and SABIC air bags on both sides of the
vehicle may deploy.
The system includes side impact sensors that are cali-
brated to deploy the Supplemental Seat-Mounted Side
Air Bags and SABIC air bags during impacts that require
side air bag occupant 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.

WARNING!(Continued)
•SAB and SABIC air bags are a supplement to the
seat belt restraint system. Occupants, including
children who are up against or very close to SAB or
SABIC air bags can be seriously 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. Always sit
upright as possible with your back against the seat
back, use the seat belts properly, and use the
appropriate sized child restraint, infant restraint or
booster seat recommended for the size and weight
of the child.

WARNING! (Continued)
•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 perma-
nent attachments (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 properly, and use the
appropriate sized child restraint, infant restraint or
booster seat recommended for the size and weight of the
child.

Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bag.
Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved 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 Federally 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 signals, a central electronicORC deploys the Advanced Front Air Bags, SABIC air
bags, SAB air bags, and front seat belt pretensioners, as
required, depending on several factors, including the
severity and type of impact.
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on several factors,
including the severity and type of collision. Advanced
Front Air Bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions.
The Advanced Front Air Bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 77

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 deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the OFF
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 approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. 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 instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
