Seat Belts And Pregnant Women
Seat belts must be worn by all occupants including preg-
nant women: the risk of injury in the event of an accident
is reduced for the mother and the unborn child if they are
wearing a seat belt.
Position the lap belt snug and low below the abdomen and
across the strong bones of the hips. Place the shoulder belt
across the chest and away from the neck. Never place the
shoulder belt behind the back or under the arm.
Seat Belt Pretensioner
The front seat belt system is equipped with pretensioning
devices that are designed to remove slack from the seat belt
in the event of a collision. These devices may improve the
performance of the seat belt by removing slack from the
seat belt 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 still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Restraint
Controller (ORC). Like the air bags, the pretensioners are
single use items. A deployed pretensioner or a deployed air
bag must be replaced immediately.
Energy Management Feature
The front seat belt system is equipped with an Energy
Management feature that may help further reduce the risk
of injury in the event of a collision. The seat belt system has
a retractor assembly that is designed to release webbing in
a controlled manner.

234 SAFETY

Supplemental Restraint Systems (SRS)
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask your autho-
rized dealer.
The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC) moni-
tors the internal circuits and interconnecting wiring asso-
ciated with the electrical Air Bag System Components.
Your vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
•Occupant Restraint Controller (ORC)
• Air Bag Warning Light
•Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags •
Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the electronic
parts of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in the
ACC position, the air bag system is not on and the air bags
will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing Light will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag Warning

SAFETY 237

The Side Air Bags will not deploy in all rollover events. The
rollover sensing-system determines if a rollover event may
be in progress and whether deployment is appropriate. A
slower-developing event may deploy the seat belt preten-
sioners on both sides of the vehicle. A faster-developing
event may deploy the seat belt pretensioners as well as the
Side Air Bags on both sides of the vehicle. The rollover
sensing-system may also deploy the seat belt pretension-
ers, with or without the Side Air Bags, on both sides of the
vehicle if the vehicle experiences a near rollover event.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.

Supplemental Seat-Mounted Side Air Bags (SABs) — If
Equipped
Your vehicle may be equipped with Supplemental Seat-
Mounted Side Air Bags (SABs). If your vehicle is equipped
with Supplemental Seat-Mounted Side Air Bags (SABs),
please refer to the information below.Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs are
marked with a “SRS AIRBAG” or “AIRBAG” label sewn
into the outboard side of the seats.
The SABs (if equipped with SABs) may help to reduce the
risk of occupant injury during certain side impacts, in
addition to the injury reduction potential provided by the
seat belts and body structure.
When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant

Air Bag System Components
NOTE:The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring associated
with electrical Air Bag System Components listed below:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
•Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters •
Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate immediately after
deployment.
NOTE: Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with the
air bag system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
• The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air bags
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.

SAFETY 249

•As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air bag
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 instructions for
cleaning.
Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will
not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assem-
blies replaced by an authorized dealer immediately.
Also, have the Occupant Restraint Controller System
serviced as well. NOTE:
•
Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine whether
to have the Enhanced Accident Response System perform
the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.
250 SAFETY

Engine Air Cleaner Filter Installation
NOTE:Inspect and clean the housing if dirt or debris is
present before replacing the air filter element.
1. Install the air cleaner filter element into the housing assembly with the air cleaner filter inspection surface
facing downward. 2. Install the air cleaner cover onto the housing assembly
locating tabs.
3. Latch the spring clips and lock the air cleaner cover to the housing assembly.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
•Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, for further warranty
information.
• The air conditioning system contains refrigerant un-
der high pressure. To avoid risk of personal injury or
