CHRYSLER PACIFICA 2005 1.G Service Manual

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 a collision.
These devices improve the performance of the seat belt
by assuring that the belt is tight about the occupant early
in a collision. Pretensioners are designed to work for all
size occupants.
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 front airbag con-
trol module (see Airbag Section). Like the front airbags,
the pretensioners are single use items. After a collision
that is severe enough to deploy the airbags and preten-
sioners, both must be replaced.
Enhanced Driver Seat Belt 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
seconds or until the driver’s seat belt is buckled.
The Enhanced Warning System (BeltAlert) will be reacti-
vated 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 RUN position. DaimlerChrysler does not recommend
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 RUN position (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 within 10 seconds, ending with the seat belt
buckled.
NOTE:Watch for the Seat Belt Warning Light to turn on
while unbuckling and off while re-buckling the seat belt.
It may be necessary to retract the seat belt.4. Turn off the engine. A single chime will sound to
signify that you have successfully completed the pro-
gramming.
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 unbuckled.
Seat Belts and Pregnant Women
We recommend that pregnant women use the seat belts
throughout their pregnancies. 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.
42 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 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 extender
and stow 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 System - Airbag
This vehicle has airbags for both the driver and front
passenger as a supplement to the seat belt restraint
systems. The driver’s front airbag is mounted in the
center of the steering wheel. The passenger’s front 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 in low
speed collisions.
The front airbags have a multi stage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
Front Airbag Components
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Also, the front passenger airbag is certified to the Federal
regulations that define Occupant Classification (Refer to
“Occupant Classification System”in this section).
This vehicle may also be equipped with a driver inflat-
able knee blocker located on the instrument panel below
the steering column.
This vehicle may also be equipped with left and right
window bags to protect the driver and 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 airbag covers
or attempt to manually open them. You may damage
the airbags and you could be injured because the
airbags are not there to protect you. These protective
covers for the airbag cushions are designed to open
only when the airbags are inflating.
•If your vehicle is equipped with left and right
window bags, do not stack luggage or other cargo up
high enough to block the location of the side curtain
airbag. The area where the side curtain airbag is
located should remain free from any obstructions.
•If your vehicle is equipped with left and right
window bags, do not have any accessory items in-
stalled 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.
Along with seat belts, and pretensioners, front airbags
work with the instrument panel knee blockers to provide
improved protection for the driver and front passenger.
Left and right 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 to“Occupant Classification Sys-
tem”in this section) has determined the seat is empty or
is occupied by a child.
If your vehicle is equipped, the window bag on the crash
side of the vehicle is triggered in moderate to severe side
collisions. But even in collisions where the airbags inflate,
you need the seat belts to keep you in the right position
for the airbags to protect you properly.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag.
1.Children 12 years old 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 front airbag.
An airbag deployment can cause severe injury or death to
infants in that position.
Children that are not big enough to properly wear the
vehicle seat belt (refer to section on Child Restraint)
should be secured in the rear seat, in a child restraint or
belt-positioning booster seat appropriate for the size and
age of the child. Older children who do not use a child
restraint or belt-positioning booster seat should ride
properly buckled up in the rear seat. Never allow chil-
dren 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. Refer to the section on Child Restraint.
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2.All occupants should wear 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 left and right window bags, do
not lean against the door, airbags will inflate forcefully
into the space between you and the door.

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 front 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 window bags, they
also need room to inflate. Do not lean against the
door or window. Sit upright in the center of the
seat.
“The Airbag System”consists of the following:
•Occupant Restraint Controller (ORC)
•AIRBAG Readiness Light
•Driver Airbag
•Front Passenger Airbag
•Window Bags above Side Windows—If Equipped
•Front Impact Sensors
•Side Impact Sensors—If Equipped
•Steering Wheel and Column
•Instrument Panel
•Seat Belt Readiness Light
•Front Seat Belt Pretensioners

How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collisionseverity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
•The ORC may modify the rate of inflation based on the
occupant size provided by the Occupant Classification
Module.
•The ORC will not detect side, roll over, or rear impacts.
•The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, instrument panel and passenger knee bol-
sters. If the key is in the OFF 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 in the center of
the instrument panel 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
to“Passenger Airbag Disable (PAD) Indicator Light”in
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.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity of
nontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be 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
