JEEP GRAND CHEROKEE 2009 WK / 3.G Service Manual

WARNING!
•A belt that is buckled into the wrong buckle will
not protect you properly. The lap portion could
ride too high on your body, possibly causing
internal injuries. Always buckle your belt into the
buckle nearest you.
•A belt that is too loose will not protect you as well.
In a sudden stop you could move too far forward,
increasing the possibility of injury. Wear your seat
belt snugly.

WARNING! (Continued)
•A belt that is worn under your arm is very danger-
ous. Your body could strike the inside surfaces of
the vehicle in a collision, increasing head and neck
injury. A belt worn under the arm can cause
internal injuries. Ribs aren’t as strong as shoulder
bones. Wear the belt over your shoulder so that
your strongest bones will take the force in a
collision.
•A shoulder belt placed behind you will not protect
you from injury during a collision. You are more
likely to hit your head in a collision if you do not
wear your shoulder belt. The lap and shoulder belt
are meant to be used together.
4. Position the lap belt across your thighs, below your
abdomen. To remove slack in the lap portion, pull up a
bit on the shoulder belt. To loosen the lap belt if it is tootight, tilt the latch plate and pull on the lap belt. A snug
belt reduces the risk of sliding under the belt in a
collision.
WARNING!
•A lap belt worn too high can increase the risk of
injury in a collision. The belt forces won’t be at the
strong hip and pelvic bones, but across your ab-
domen. Always wear the lap part of your seat belt
as low as possible and keep it snug.
•A twisted belt can’t do its job as well. In a collision
it could even cut into you. Be sure the belt is
straight. If you can’t straighten a belt in your
vehicle, take it to your authorized dealer and have
it fixed.
5. Position the shoulder belt on your chest so that it is
comfortable and not resting on your neck. The retractor
will withdraw any slack in the belt.

6. To release the belt, push the red button marked PRESS
on the buckle. The belt will automatically retract to its
stowed position. If necessary, slide the latch plate down
the webbing to allow it to retract fully.
WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do
not disassemble or modify the system. Seat belt
assemblies must be replaced after an accident if they
have been damaged (bent retractor, torn webbing,
etc.).
Adjustable Upper Shoulder Belt Anchorage
In the front seating positions, the shoulder belt can be
adjusted upward or downward to position the belt away
from your neck. Press the release button to release the
anchorage, and then move it up or down to the position
that serves you best.Removing Slack from Belt

As a guide, if you are shorter than average, you will
prefer a lower position, and if you are taller than average,
you’ll prefer a higher position. When you release the
anchorage, try to move it up or down to make sure that
it is locked in position.
Automatic Locking Mode — 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.
When to Use the Automatic Locking Mode
Use Automatic Locking mode anytime a child safety seat
is installed in the rear center seating position. Children
12 years old and younger should be properly restrained
in the rear seat whenever possible.
How to Use 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 fully extended.
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.Adjusting Upper Shoulder Belt
42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

How to Disengage the Automatic Locking Mode
Disconnect the combination lap/shoulder belt and allow
it to retract completely to disengage the Automatic
Locking mode and activate the Vehicle Sensitive (Emer-
gency) Locking mode.
Energy Management Feature
This 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 assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.
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.
Seat Belt Pretensioners
The driver and front passenger seat belts are equipped
with a pretensioning device that is designed to remove
any slack from the seat belt systems in the event of a
collision. This device improves the performance of the
seat belt by assuring that the belt is tight around the
occupant early in a collision. Pretensioners work for all
size occupants, including those in child restraints.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 43

NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Control (ORC). Like the front airbags, the preten-
sioners are a single use item. After a collision that is
severe enough to deploy the airbags and pretensioners,
they must be replaced.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
If the driver’s seat belt has not been buckled within
60 seconds of starting the vehicle and if the vehicle speed
is greater than 5 mph (8 km/h), the Enhanced Seat Belt
Use Reminder System (BeltAlert) will alert the driver to
buckle the seat belt. The driver should also instruct all
other occupants to buckle their seat belts. Once the
warning is triggered, BeltAlertwill continue to chime
and flash the Seat Belt Reminder Light for 96 seconds oruntil the driver’s seat belt is buckled. BeltAlertwill be
reactivated if the driver’s seat belt is unbuckled for more
than 10 seconds and the vehicle speed is greater than
5 mph (8 km/h).
BeltAlertcan 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
or START position. Chrysler LLC does not recommend
deactivating BeltAlert.
1. Turn the ignition switch to the OFF position, and
buckle the driver’s seat belt.
2. Turn the ignition key to the ACC/ON position (engine
does not need to be running), and wait for the Seat Belt
Reminder Light to turn off.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
BeltAlertcan be reactivated by repeating this procedure.
NOTE:Although BeltAlerthas been deactivated, the
Seat Belt Reminder Light will continue to illuminate
while the driver’s seat belt remains unfastened.
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 a collision.
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.
Driver and Front Passenger Supplemental
Restraint Systems (SRS)
This vehicle has airbags for both the driver and right
front passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
steering wheel. The front passenger airbag is mounted in
the instrument panel, above the glove compartment. The
words SRS/AIRBAG are embossed on the airbag covers.NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.
1 — Driver Airbag
2 — Passenger Airbag
3 — Knee Bolster 46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The front airbags have a multistage inflator design. This
may allow the airbags to have different rates of inflation
that are based on collision severity and occupant size.
This vehicle is equipped with window bags to protect the
driver, and front and rear passengers sitting next to a
window. They are located above the side windows. Their
covers are also labeled SRS/AIRBAG.
NOTE:Airbag covers may not be obvious in the interior
trim; but they will open to allow airbag deployment.

WARNING!
•Do not put anything on or around the front airbag
covers or attempt to manually open them. You may
damage the airbags and you could be injured
because the airbags are no longer functional.
These protective covers for the airbag cushions are
designed to open only when the airbags are inflat-
ing.
•Do not stack luggage or other cargo up high
enough to block the location of the window bag.
The area where the window bag is located should
remain free from any obstructions.

WARNING! (Continued)
•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 attachments (bolts or screws) for instal-
lation on the vehicle roof. Do not drill into the roof
of the vehicle for any reason.
•Do not cover or place items on the airbag covers.
These items may cause serious injury during
inflation.
NOTE:Do not use a clothing bar mounted to the coat
hooks in this vehicle. A clothing bar will impede the
proper performance of the window bags.
The front airbags have a multistage inflator design. This
allows the airbags to have different rates of inflation that
are based on collision severity. Along with the seat belts,
