JEEP GRAND CHEROKEE 2011 WK2 / 4.G Repair Manual

Seat Belts In Passenger Seating Positions
The seat belts in the passenger seating positions are
equipped with Automatic Locking Retractors (ALR)
which are used to secure a child restraint system. For
additional information refer to “Installing Child Re-
straints Using The Vehicle Seat Belt” under the “Child
Restraints” section. The chart below defines the type of
feature for each seating position.

•N/A — Not Applicable
•ALR — Automatic Locking Retractor If the passenger seating position is equipped with an
ALR and is being used for normal usage:
Only pull the belt webbing out far enough to comfortably
wrap around the occupants mid-section so as to not
activate the ALR. If the ALR is activated you will hear a
ratcheting sound as the belt retracts. Allow the webbing
to retract completely in this case and then carefully pull
out only the amount of webbing necessary to comfort-
ably wrap around the occupants mid-section. Slide the
latch plate into the buckle until you hear a
click.

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 avail-
able on all passenger-seating positions with a combina-
tion 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 downward 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 vehicle sensitive (emergency)
locking mode.
WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly Automatic Locking Re-
tractor (ALR) feature or any other seat belt func-
tion is not working properly when checked ac-
cording to the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of an
accident. These devices may improve the performance of
the seat belt by assuring that the belt is tight about the
occupant early in an accident. Pretensioners work for all
size occupants, 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 Re-
straint Controller (ORC). Like the airbags, the pretension-
ers are single use items. A deployed pretensioner or a
deployed airbag must be replaced immediately.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable compo-
nents, and vehicles with this equipment cannot be readily
identified by any markings, only through visual inspec-
tion of the head restraint. 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) determines
whether the severity, or type of rear impact will require
the Active Head Restraints (AHR) to deploy. If a rear
impact requires deployment, both the driver and front
passenger seat AHRs will be deployed.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

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 sever-
ity and type of the impact.

CAUTION!
All occupants, including the driver, should not oper-
ate 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 an
accident.
NOTE: For more information on properly adjusting and
positioning the head restraint, refer to “Adjusting Active
Head Restraints” in “Understanding The Features Of
Your Vehicle”.
Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered in an accident,
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 deployed AHR at
a comfortable position.Hand Positioning Points On AHR

NOTE:
•If you have difficulties or problems resetting the
Active Head Restraints, see an authorized dealer.
•For safety reasons, have the Active Head Restraints
checked by a qualified specialist at an authorized
dealer.
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 seatbelts. This feature is active
whenever the ignition 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 seatbelts are
fastened. BeltAlert triggers within 60 seconds of vehicle
speed over 5 mph (8 km/h). The reminder sequence lasts
for 96 seconds or until the respective seatbelts are fas-
tened. After the sequence completes, the Seat Belt Re-
minder Light remains illuminated until front belts are
fastened. The driver should instruct all other occupants
to fasten their seatbelts. If a front seatbelt is unbuckled
while traveling at speeds greater than 5 mph (8 km/h),
BeltAlert will chime as a single notification and illumi-
nate the Seat Belt Reminder Light, then will proceed to
the 96 second reminder sequence.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

The front passenger seat BeltAlertis not active when the
front passenger seat is unoccupied. 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 or by following these steps:
NOTE: The following steps must occur within the first
60 seconds of the ignition switch being turned to the
ON/RUN or START position. Chrysler Group LLC does
not recommend deactivating BeltAlert.
1. With all doors closed, and the ignition switch in any
position except ON/RUN or START, buckle the driver ’s
seatbelt. 2. Turn the ignition key to the ACC or ON/RUN position
(do not start the engine), and wait for the Seat Belt
Reminder Light to turn off.
3. Within 60 seconds of starting the vehicle, unbuckle
and then re-buckle the driver’s seat belt at least three
times within 10 seconds, ending with the seat belt
buckled.
4. Turn the ignition key to the OFF position. A single
chime will sound to signify that you have successfully
completed the programming.
NOTE:
Watch for the Seat Belt Reminder Light to turn
on while the seat belt retracts and turn off while re-
buckling the seat belt.
BeltAlert can be reactivated by repeating this procedure.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:Although BeltAlert has been deactivated, the
Seat Belt Reminder Light will continue to illuminate
while the driver ’s or front passenger ’s (if equipped with
belt alert) seat belt remains unfastened.
Seatbelt Lock Out
The 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 Women
We 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.
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 an accident. 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.

Supplemental Restraint System (SRS) — Airbags
This vehicle has Advanced Front Airbags 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 Airbag is mounted in the
instrument panel, above the glove compartment. The
words SRS AIRBAG are embossed on the airbag covers.NOTE:These airbags are certified to the new Federal
regulations for Advanced Airbags.
The Advanced Front Airbags have a multistage inflator
design. This allows the airbag to have different rates of
inflation based on the severity and type of collision.
