2008 JEEP GRAND CHEROKEE warning

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.

WARNING!
²The belt and retractor assembly must be replaced
if the seat belt assembly ªautomatic locking retrac-
torº feature or any other seat belt function is not
working properly when checked according to the
procedures in the Service Manual.
²Failure 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.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) Module. Like the front airbags, the
pretensioners 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 Warning
System (BeltAlert) will alert the driver to buckle their seat
belt. The driver should also instruct all other occupants to
buckle their seat belts. Once the warning is triggered, the
Enhanced Warning System (BeltAlert) will continue to
chime and flash the Seat Belt Warning Light for 96
42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

seconds or until the driver's seat belt is buckled. The
Enhanced Warning System (BeltAlert) will 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).
The Enhanced Warning System (BeltAlert) can be en-
abled 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. The manufacturer does not recom-
mend deactivating the Enhanced Warning System
(BeltAlert).
1. Turn the ignition switch to the OFF position, and
buckle the driver's seat belt.2. Turn the ignition key to the ACCESSORY/RUN posi-
tion (engine does not need to be running), and wait for
the Seat Belt Warning 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 with 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.
The Enhanced Warning System (BeltAlert) can be reacti-
vated by repeating this procedure.
NOTE:Although the Enhanced Warning System
(BeltAlert) has been deactivated, the Seat Belt Warning
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.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

This vehicle is equipped with window bags to protect the
driver, front, and rear passengers sitting next to a win-
dow. 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!
²Do 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 inflating.
²Do 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.
²Do 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 installation on the
vehicle roof. Do not drill into the roof of the vehicle
for any reason.
²Do not cover or place items on the airbag covers. These
items may cause serious injury during inflation.
Window Airbag Location

seat as far back as possible, and use the proper child
restraint. See ªChild Restraintº in this section.
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. All occupants should use their lap and shoulder belts
properly.
3. The driver and front passenger seats should be moved
back as far as practical to allow the front airbags room to
inflate.
4. Do not lean against the door or window, airbags will
inflate forcefully into the space between you and the
door.
5. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided under ªIf
You Need Assistanceº in Section 9 of this manual.WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you have
airbags.
²Being too close to the steering wheel or instrument
panel during airbag deployment could cause seri-
ous injury. Airbags need room to inflate. Sit back,
comfortably extending your arms to reach the
steering wheel or instrument panel.
²The left and right side curtain airbags need room
to inflate. Do not lean against the door or window.
Sit upright in the center of the seat.

Airbag System Components
The airbag system consists of the following:
²Occupant Restraint Control Module
²Airbag Warning Light
²Driver Airbag
²Passenger Airbag
²Side Curtain Airbags above Side Windows
²Side Remote Acceleration Sensors
²Steering Wheel and Column
²Instrument Panel
²Interconnecting Wiring
²Knee Impact Bolsters
²Front Acceleration Sensors
²Driver and Front Passenger Seat Belt Pretensioner
How The Airbag System Works
²
TheOccupant Restraint Control (ORC) Modulede-
termines if a frontal, side, or rollover collision is severe
enough to require the front and/or side airbags to
inflate. The front airbag inflators are designed to
provide different rates of airbag inflation from direc-
tion provided by the ORC. The ORC will not detect
rear impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

Also, the ORC turns on the ªAirbag Warning
Lightº for 6 to 8 seconds for a self-check
when the ignition is first turned on. After the
self-check, the ªAirbag Warning Lightº will
turn off. If the ORC detects a malfunction in any part
of the system, it turns on the ªAirbag Warning Lightº
either momentarily or continuously. A single chime
will sound if the light comes on again after initial start
up.
WARNING!
Ignoring the ªAirbag Warning Lightº in your instru-
ment panel could mean you won't have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked right
away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50±70 milliseconds. This is
about half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.
