SAFETY285
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 94.
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.

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system
provides output appropriate to the severity and
type of collision as determined by the Occupant
Restraint Controller (ORC), which may receive
information from the front impact sensors (if
equipped) or other system components.
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.

2 — Driver And Passenger Knee Impact Bolsters
WARNING!
Being too close to the steering wheel or instru -
ment panel during front air bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfort -
ably extending your arms to reach the steering
wheel or instrument panel.
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.

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 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
ON/RUN. 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
Ú page 275.
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.
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.

NOTE:
P (Passenger) — Metric tire sizing is based on US
design standards. P-Metric tires have the letter
“P” molded into the sidewall preceding the size
designation. Example: P215/65R15 95H.
European — Metric tire sizing is based on Euro -
pean design standards. Tires designed to this
standard have the tire size molded into the side -
wall beginning with the section width. The letter
"P" is absent from this tire size designation.
Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based on
US design standards. The size designation for
LT-Metric tires is the same as for P-Metric tires
except for the letters “LT” that are molded into
the sidewall preceding the size designation.
Example: LT235/85R16.
Temporary spare tires are designed for tempo -
rary emergency use only. Temporary high pres -
sure compact spare tires have the letter “T” or
“S” molded into the sidewall preceding the size
designation. Example: T145/80D18 103M.
High flotation tire sizing is based on US design
standards and it begins with the tire diameter
molded into the sidewall. Example: 31x10.5
