CHRYSLER PACIFICA 2004 1.G Service Manual

The Enhanced Warning System (BeltAlertŸ) 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. DaimlerChrysler 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. Start the engine 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.4. Turn off the engine. A single chime will sound to
signify that you have successfully completed the pro-
gramming.
The Enhanced Warning System (BeltAlertŸ) can be reac-
tivated by repeating this procedure.
NOTE:Although the Enhanced Warning System (BeltA-
lertŸ) 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.

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
allows the airbag to have different rates of inflation that
are based on collision severity.

This vehicle is also equipped with a driver inflatable knee
blocker located on the instrument panel below the steer-
ing column.
This vehicle may also be equipped with left and right
side curtain airbags to protect the driver and passengers
sitting next to a window. If the vehicle is equipped with
side curtain airbags, 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 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.
²If your vehicle is equipped with left and right side
curtain airbags, 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.
²If your vehicle is equipped with left and right side
curtain airbags, 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
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
Airbags inflate in moderate to high speed impacts. 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 side curtain airbags 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 only in moderate
to severe frontal collisions. If your vehicle is equipped,
the side curtain airbag on the crash side of the vehicle is
triggered in moderate to severe side collisions. In certain
types of collisions where the airbags deploy, 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 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 side curtain airbags,
do not lean against the door, airbags will inflate force-
fully into the space between you and the door.

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 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.
²If 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.
ªThe Front Airbag Systemº consists of the following:
²Airbag Control Module (with integrated impact sen-
sor)
²AIRBAG Readiness Light
²Driver Airbag
²Front Passenger Airbag
²Seat Belt Pretensioners
²Steering Wheel and Column
²Instrument Panel
²Seat Belt Readiness Light
²Interconnecting Wiring
²Passenger Knee Impact Blocker
²Driver Inflatable Knee Blocker

How The Airbag Systems Work
²
The airbag control module determines if an impact is
severe enough to require the airbags to inflate. Based
on the level of collision severity, the control module
determines the proper rate of inflation. The front
airbag inflators are designed to provide different rates
of airbag inflation. The airbag control module will not
detect roll over collisions.
The airbag control module 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 under ªThe Front Airbag
Systemº, except the passenger knee blocker, instru-
ment panel and the steering wheel and column. If the
key is in the OFF position, in the ACC position, or not
in the ignition switch, the front airbags are not on and
will not inflate.The airbag control module sends a message
to the instrument cluster to turn on the
AIRBAG light in the instrument panel for 6
to 8 seconds when the ignition switch is first
turned ON, then turns the light off. If the airbag
control module detects a malfunction in any part of the
system, the airbag light will turn on either momen-
tarily or continuously.
WARNING!
Ignoring the AIRBAG light in your instrument 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.

²When the airbag control module detects a collision
requiring theFront Airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different front airbag inflation
rates are possible, these rates are determined by the
airbag control module based on collision severity. The
front airbag covers separate and fold out of the way as
the front airbags inflate to their full size. The front
airbags fully inflate in about 50 milliseconds. This is
only about half of the time it takes you to blink your
eyes. The front airbags then quickly deflate while
helping to restrain the driver and front passenger. The
driver's and passenger's front airbag gas is vented
through the airbag material and small vent openings
towards the instrument panel. In this way the front
airbags do not interfere with your control of the
vehicle.
²TheSupplemental Side Curtain Airbagsare designed
to activate only in certain side collisions. When theairbag control module detects a collision requiring the
side curtain airbags to inflate, it signals the inflators on
the crash side of the vehicle. A quantity of nontoxic gas
is generated to inflate the side curtain airbag. The
inflating side curtain airbag pushes the outside edge of
the headliner out of the way and inflates (in about the
same time it takes to blink your eyes). A properly
belted and seated occupant is less likely to be injured
by the force of the airbag or crash event. Items that are
positioned in the area where the side curtain airbag
inflates can reduce the effectiveness of the airbag and
also increase the likelihood of injuries to the occu-
pants, this especially applies to children. The side
curtain airbag is about 4 inches (10 cm) thick when it
is inflated.
²When the airbag control module detects a collision
requiring theDriver Inflatable Knee Blocker,it
signals the inflator unit. A quantity of nontoxic gas is
generated to inflate the Driver Inflatable Knee Blocker.

The Driver Inflatable Knee Blocker inflates rearward
towards the driver's knees to help protect the knees
and position you for the best interaction with the front
airbag. The Driver Inflatable Knee Blocker fully in-
flates in about 50 milliseconds, this is only about half
of the time it takes you to blink your eyes. It then
quickly deflates while helping to protect the driver's
knees.
²The Knee Impact Blockershelp protect the knees and
position you for the best interaction with the front
airbags.
Side Airbags Supplemental Restraint System
(SRS) Ð If Equipped
ªSupplemental Side Curtain Airbag Systemº, on ve-
hicles equipped, consists of the following:
²AIRBAG Readiness Light (shared with the front airbag
system)
²Left and Right Side Curtain Airbags Above Side
Windows
²Airbag Control Module
²Interconnecting Wiring
If An Airbag Deployment Occurs
The airbag systems are designed to deploy when the
airbag control modules detect a moderate-to-severe col-
lision, to help restrain the driver and front passenger, and
then immediately deflate.
NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision which deploys the airbag, any
or all of the following may occur:
