CHRYSLER 300 LX 2006 Service Manual

Along with the seat belts, front airbags work with the
instrument panel knee bolsters to provide improved
protection for the driver and front passenger. Side Cur-
tain Airbags also work with seat belts to improve occu-
pant 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
Classification System (refer to information on Occupant
Classification System in this section) has determined the
passenger seat is empty or is occupied by someone that is
classified in thesmall childcategory.
If your vehicle is so equipped, the Side Curtain Airbag on
the crash side of the vehicle is triggered in moderate to
severe side collisions. 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 old and under should ride buckled
up in the rear seat. Infants in rear-facing child restraints
shouldNEVERride in the front seat of a vehicle with a
passenger front airbag. An airbag deployment could
cause severe injury or death to infants in that position.
Children that are not big enough to wear the vehicle seat
belt properly (refer to information on Child Restraint in
this section) should be secured in the rear seat in child
restraints or belt-positioning booster seats.
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 (refer to information on Child Restraint in this
section).

2. You should read the instructions provided with your
child restraint to make sure that you are using it properly.
3. All occupants should use their seat belts properly.
4. The driver and front passenger seats should be moved
back as far as practical to allow the airbags time to inflate.
5. If your vehicle has left and right side curtain airbags,
do not lean against the door, airbags will inflate forcefully
into the space between you and the door.
6. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided in theIf
You Need Customer Assistancesection in 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 Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC may
also modify the rate of inflation based on the occupant
size provided by the Occupant Classification Module.
The ORC will not detect roll over.
•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 in the instru-
ment 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
information on Passenger Airbag Disable (PAD) Indi-
cator 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 continu-
ously. A single chime will sound if the light comes on
again after initial start up.
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.
•TheOccupant Classification System (OCS)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.
NOTE:Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
•ThePassenger Air Bag Disable (PAD) Indicator Light
(an amber light located in the center of the instrument
panel) tells the driver and front passenger when the
front passenger air bag is turned off. The PAD indica-
tor light illuminates the front passenger air bag icon
and the wordsPASS AIR BAG OFFto show that the
passenger air bag will not inflate during a collision
requiring air bags. When the right front passenger seat
is empty or when very light objects are placed on the
seat, the passenger air bag 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 air bag is ready to be inflated
if a collision requiring an air bag occurs.
For almost all properly installed rear facing child
restraints, the PAD indicator light will be illuminated
indicating that the front passenger air bag is turned offand will not inflate. If the PAD indicator light is not
illuminated,DO NOTassume the air bag is turned off
and move the child restraint to the rear seat. A
deploying passenger air bag can cause death or seri-
ous 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 (refer to information on Child
Restraint in this section).

The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult
will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the PAD
Indicator Light is not illuminated when an adult is riding
in the front passenger seat. If an adult occupant’s weight
is transferred to another part of the vehicle (like the door
or instrument panel), the weight sensors in the seat may
not properly classify the occupant. Objects lodged under
the seat or between the seat and the center console can
prevent the occupant’s weight from being measured
properly and may result in the occupant being improp-
erly classified. Ensure that the front passenger seat back
does not touch anything placed on the back seat becausethis can also affect occupant classification. Also, if you
fold down the rear seat check to be sure it doesn’t touch
the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the Airbag Warning
Light (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The Airbag Warning Light is turned on
whenever there is fault that can affect the operation of the
airbag system. If there is a fault present in the OCS, both
the PAD Indicator Light and the Airbag Warning Light
are illuminated to show that the passenger airbag is
turned off until the fault is cleared. If an object is lodged
under the seat and interferes with operation of the weight
sensors, a fault will occur which turns on both the PAD

Indicator Light and the Airbag Warning Light. Once the
lodged object is removed, the fault will be automatically
cleared after a short period of time.
•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 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
may be possible based on collision severity and occu-
pant 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’s front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
troller (ORC). The ORC uses the occupant category to
determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•TheSide Impact SRS Side Curtain Airbagare de-
signed to activate only in certain side collisions. When
the ORC (with side impact option) detects a collision
requiring the side curtain airbag 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
covers the window. The airbag inflates in about 30

milliseconds (about one quarter of the time it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is only about 3-1/2 inches (9 cm) thick
when it is inflated.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.The following requirements must be strictly adhered to:
•Do not modify the front passenger seat assembly or
components in any way.
•Do not modify the front seat center console or center
position seat in any way.
•Do not use prior or future model year seat covers not
designated for the specific model being repaired. Al-
ways use the correct seat cover specified for the
vehicle.
•Do not replace the seat cover with an aftermarket seat
cover.
•Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar.
•At no time should any supplemental restraint system
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by DaimlerChrysler/
Mopar.

WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag deployment in case of a frontal crash. This
could result in death or serious injury to the front
seat passenger if the vehicle is involved in an acci-
dent. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Standards
(FMVSS).
If A Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Controller detects a moderate-to-
severe collision, to help restrain the driver and front
passenger, and then to immediately deflate.
NOTE:A frontal 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 airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
However, if you haven’t healed significantly within a
few days, or if you have any blistering, see your doctor
immediately.
•As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc-
tions for cleaning.

•It is not advisable to drive your vehicle after the
airbags have been deployed. If you are involved in
another collision, the airbags will not be in place to
protect you.
WARNING!
Deployed airbags can’t protect you in another colli-
sion. Have the airbags replaced by an authorized
dealer as soon as possible.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could
cause it to fail when you need it. You could be
injured because the airbags are not there to protect
you. Do not modify the components or wiring,
including adding any kind of badges or stickers to
the steering wheel hub trim cover or the upper right
side of the instrument panel. Do not modify the front
bumper, vehicle body structure, or frame.
•You need proper knee impact protection in a colli-
sion. Do not mount or locate any aftermarket equip-
ment on or behind the knee impact bolster.
•Do not place or hang any items such as add-on video
players on the right front passenger seat back. The
additional weight may cause the Occupant Classifi-
cation System to be unable to correctly classify the
right front occupant. This could allow the passenger
frontal airbag to inflate when it is not desired.
•It is dangerous to try to repair any part of the airbag
system yourself. Be sure to tell anyone who works on
your vehicle that it has airbags.
