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 — If Equipped •
Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners — If Equipped
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
Light, either momentarily or continuously. A single chime
will sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is

detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air
bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
•The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protection.
Have an authorized dealer service the air bag system
immediately.WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.
Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are
a supplement to the seat belt restraint systems. The driver
front air bag is mounted in the center of the steering wheel.
The passenger front air bag is mounted in the instrument
panel, above the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on the air bag
covers.
198 SAFETY

inflate in less time than it takes to blink your eyes. The
front air bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the front air bags.
WARNING!
•Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.
Supplemental Side Air Bags
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

SAFETY 201

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.
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 — If Equipped
• Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners — If Equipped
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 205

•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.
206 SAFETY

The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving,
have the system inspected at your authorized dealer as
soon as possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air
Bag System has been detected. It will stay on until the
fault is cleared. If the light comes on intermittently or
remains on while driving, have your authorized dealer
service the vehicle immediately. Refer to “Occupant
Restraint Systems” in “Safety” for further information.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only
use a floor mat that does not interfere with the operation of
the accelerator, brake or clutch pedals. Only use a floor mat
234 SAFETY

that is securely attached using the floor mat fasteners so it
cannot slip out of position and interfere with the accelera-
tor, brake or clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded, or stacked
floor mat, or damaged floor mat fasteners may cause
your floor mat to interfere with the accelerator, brake,
or clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
•ALWAYS securely attach
your floor mat using the
floor mat fasteners. DO NOT install your floor mat
upside down or turn your floor mat over. Lightly pull
to confirm mat is secured using the floor mat fasten-
ers on a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE
before installing any other
floor mat. NEVER install or stack an additional floor
mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle.
NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat

WARNING! (Continued)
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
•
ONLY use the driver ’s side floor mat on the driver ’s
side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch pedal
(if present) to check for interference. If your floor mat
interferes with the operation of any pedal, or is not
secure to the floor, remove the floor mat from the
vehicle and place the floor mat in your trunk.
• ONLY use the passenger ’s side floor mat on the
passenger ’s side floor area.
• ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.

•If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel bolts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.
236 SAFETY

under which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as a problem. Please check your oil level with
the engine oil indicator often during the break in period.
Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the trans-
mission in PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle. When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
•
When the parking brake is applied and the transmission
is placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application.
Parking Brake Release

STARTING AND OPERATING 245

When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
•
Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Leaving unattended children
in a vehicle is dangerous for a number of reasons. A
child or others could be seriously or fatally injured.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the
ACC or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.

WARNING! (Continued)
•Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle or it may roll and cause damage or
injury. Also, be certain to leave the transmission in
PARK. Failure to do so may cause the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
