JEEP GRAND CHEROKEE 2006 WK / 3.G SRT Service Manual

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 passenger side 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.
The front airbags have a multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
Also, the front passenger airbag is certified to the Federal
regulations that define Occupant Classification (Refer to
Occupant Classification Systemin this section).

This vehicle may also be equipped with window bags to
protect the driver, front, and rear passengers sitting next
to a window. If the vehicle is equipped with window
bags, 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 be-
cause the airbags are no longer functional. These
protective covers for the airbag cushions are de-
signed to open only when the airbags are inflating.
•If your vehicle is equipped with window bags, 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.
•If your vehicle is equipped with window 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.
•Do not cover or place items on the airbag covers. These
items may cause serious injury during inflation.
The front airbags have a multi stage inflator design. This
allows the airbag to have different rates of inflation that
are based on collision severity. Along with the seat belts,
front airbags work with the instrument panel knee bol-
sters to provide improved protection for the driver and
front passenger. Window bags also work with seat belts
to improve occupant protection.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions.
NOTE:The passenger front airbag may not deploy even
when the driver front airbag has if the Occupant Classi-
fication System (refer toOccupant Classification System
in this section) has determined the passenger seat is
empty or is occupied by someone that is classified in the
small childcategory.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If your vehicle is so equipped, the window bag on the
crash side of the vehicle is triggered in moderate to
severe side collisions. In certain types of collisions, both
the front and side airbags may be triggered. But even in
collisions where the airbags work, you need the seat belts
to keep you in the right position for the airbags to protect
you properly.
Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag.
1. Children 12 years and under should always ride
buckled up in a rear seat.
Infants in rear facing child restraints shouldNEVERride
in the front seat of a vehicle with a passenger airbag. An
airbag deployment could cause severe injury or death to
infants in that position.Children that are not big enough to properly wear the
vehicle seat belt should be secured in the rear seat, in a
child restraint or belt-positioning booster seat. Older
children who do not use child restraints or belt-
positioning booster seats should ride properly buckled
up in the rear seat. Never allow children to slide the
shoulder belt behind them or under their arm.
If a child from 1 to 12 years old must ride in the front
passenger seat because the vehicle is crowded, move the
seat as far back as possible, and use the proper child
restraint. See “Child Restraint” 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. If your vehicle has window bags, 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 “If
You Need Assistance” in Section 9 of this manual.WARNING!
•Relying 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.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has left and right side curtain
airbags, they also need room to inflate. Do not
lean against the door or window. Sit upright in the
center of the seat.

How The Airbag System Works
•
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 may also modify
the rate of inflation based on the occupant size pro-
vided by the Occupant Classification Module. The
ORC will detect roll overs, not rear impacts.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 47

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 “Airbag Warning
Light” and “PAD Indicator Light” for 6 to 8
seconds for a self-check when the ignition is
first turned on. After the self-check, the
“Airbag Warning Light” will turn off. The “PAD
Indicator Light” will function normally (Refer toPas-
senger Airbag Disable (PAD) Indicator Lightin this
section). If the ORC detects a malfunction in any part
of the system, it turns on the “Airbag Warning Light”either momentarily or continuously. A single chime
will sound if the light comes on again after initial start
up.
WARNING!
Ignoring the “Airbag Warning Light” 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.
•TheOccupant Classification System (OCS) (If
Equipped)is part of a Federally regulated safety
system required for this vehicle. It is designed to turn
off the front passenger airbag in the unlikely event that
a rear-facing infant seat is in the front passenger seat.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
•ThePassenger Airbag Disable (PAD) Indicator Light
(If Equipped)(an amber light located in the center of
the instrument panel) tells the driver and front pas-
senger when the front passenger airbag is turned off.
The “PAD Indicator Light” illuminates the words
PASS AIR BAG OFFto show that the passenger
airbag will not inflate during a collision requiring
airbags. When the right front passenger seat is empty
or when very light objects are placed on the seat, the
passenger airbag will not inflate even though the
“PAD Indicator Light” is not illuminated.

The “PAD Indicator Light” should not be illuminated
when teenagers, most children in a forward-facing
child restraint or booster seats, most children that can
properly wear the vehicle’s seat belt, and when an
adult passenger is properly seated in the front passen-
ger seat. In this case, the airbag is ready to be inflated
if a collision requiring an airbag occurs.
For almost all properly installed rear facing child re-
straints, the “PAD Indicator Light” will be illuminated
indicating that the front passenger airbag is turned off
and will not inflate. If the “PAD Indicator Light” is not
illuminated,DO NOTassume the airbag is turned off
and move the child restraint to the rear seat. A deploying
passenger airbag can cause death or serious injury to a
child in a rear facing infant seat.NOTE:Even though this vehicle is equipped with an
Occupant Classification System, children 12 years and
under should always ride buckled up in a rear seat in an
appropriate child restraint.
