Air Bag Warning Light
The Occupant Restraint Controller (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 Warning 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 diagnostics 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 igni
-
tion 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 intermit -
tently 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.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The
Redundant Air Bag Warning Light will stay on until
the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag
Warning Light has come on and a fault has been
detected. If the Redundant Air Bag Warning Light
comes on intermittently or remains on while driving
have an authorized dealer service the vehicle
immediately Ú page 128.
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.

SAFETY TIPS
TRANSPORTING PASSENGERS
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
TRANSPORTING PETS
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown about
and possibly injured, or injure a passenger during
panic braking or in a collision. Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that are
secured by seat belts.
SAFETY CHECKS YOU SHOULD MAKE
I
NSIDE 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.
If your vehicle is involved in a collision, or if you
have questions regarding the seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.
Air Bag Warning Light
The Air Bag Warning Light will turn on for
four to eight seconds as a bulb check
when the ignition switch is first placed in
the ON/RUN position. If the light is either
not on during starting, stays on, or turns on while
driving, have the system inspected at an
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
removed. If the light comes on intermittently or
remains on while driving, have an authorized
dealer service the vehicle immediately.
See Ú
page 334 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 an authorized dealer for service if
your defroster is inoperable.
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 that is securely
attached using the floor mat fasteners so it cannot
slip out of position and interfere with the
accelerator, brake or clutch pedals or impair safe
operation of your vehicle in other ways.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a colli -
sion, people riding in these areas are more
likely to be seriously injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and
seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
