disabled person, refer to the “Customer
Assistance” section for customer service
contact information.Seat Belt Systems
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and could cause a
collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save
lives, and they can reduce the seriousness of
injuries in a collision. Some of the worst inju -
ries happen when people are thrown from the
vehicle. Seat belts reduce the possibility of
ejection and the risk of injury caused by
striking the inside of the vehicle. Everyone in
a motor vehicle should be belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Front And Rear Seat BeltAlert (If Equipped)
Front Seat BeltAlert
BeltAlert is a feature intended to remind
the driver and outboard front seat passenger
to buckle their seat belts. The BeltAlert
feature is active whenever the ignition switch
is in the START or ON/RUN position. Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi
-
tion a chime will signal for a few seconds. If
the driver or outboard front seat passenger is
unbuckled when the ignition switch is first in
the START or ON/RUN position the respec -
tive Seat Belt Reminder Light will turn solid
red and remain red until the seat belt is
buckled. The respective Seat Belt Reminder
Light will turn solid green once the seat belt
is buckled. After the driver and outboard
front seat passenger have buckled their seat
belts all Seat Belt Reminder Lights will turn
off. The outboard front passenger seat
BeltAlert is not active when the outboard
front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or
outboard front seat passenger is unbuckled
(the outboard front passenger seat BeltAlert
is not active when the outboard front
passenger seat is unoccupied). The BeltAlert
warning sequence starts by blinking the
respective Seat Belt Reminder Light and
sounding an intermittent chime. Once the

Switchable Automatic Locking Retractor (ALR) Locations — Sliding and Fixed Seats
If the passenger seating position is equipped
with an ALR and is being used for normal
usage, only pull the seat belt webbing out far
enough to comfortably wrap around the
occupant’s mid-section so as to not activate
the ALR. If the ALR is activated, you will
hear a clicking sound as the seat belt
retracts. Allow the webbing to retract
completely in this case and then carefully
pull out only the amount of webbing neces -
sary to comfortably wrap around the occu -
pant’s mid-section. Slide the latch plate into
the buckle until you hear a "click." In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack in
the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is
installed in a seating position that has a seat
belt with this feature. Children 12 years old
and under should always be properly
restrained in the rear seat of a vehicle with a
rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull downward until the entire seat belt is
extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen -
gage the Automatic Locking Mode and acti -
vate the vehicle sensitive (emergency)
locking mode.

NEVER use a rearward facing child
restraint on a seat protected by an
ACTIVE AIRBAG in front of it, DEATH or
SERIOUS INJURY to the CHILD can
occur.
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.
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.

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 an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal
circuits and interconnecting wiring associ-
ated with the electrical Air Bag System
Components. Your vehicle may be equipped
with the following Air Bag System Compo -
nents:
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
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
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.
Failure to replace the seat belt assembly
could increase the risk of injury in
collisions.
Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or
forward-facing child restraints that have
a harness for restraining the child.

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 inter-
mittently 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.
For additional information regarding the
Redundant Air Bag Warning Light refer to
“Getting To Know Your Instrument Panel”
section of this manual.
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 supple -
ment 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.

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 fric-
tion rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chem-
icals. 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 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 irri -
tation, move to fresh air. If the irritation
continues, see your doctor. If these parti -
cles 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. 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 immedi
-
ately.
Enhanced Accident Response System
In the event of an impact, if the communica -
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the Occupant Restraint Controller
(ORC) will determine whether to have the
Enhanced Accident Response System
perform the following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor
(if equipped)
Flash hazard lights as long as the battery
has power
Turn on the interior lights, which remain
on as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
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 assemblies replaced by an
authorized dealer immediately. Also, have
the Occupant Restraint Controller System
serviced as well.

Event Data Recorder (EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
How various systems in your vehicle were
operating;
Whether or not the driver and passenger
safety belts were buckled/fastened;
How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
How fast the vehicle was traveling.These data can help provide a better under
-
standing of the circumstances in which
crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if
a non-trivial crash situation occurs; no data
are recorded by the EDR under normal
driving conditions and no personal data (e.g.,
name, gender, age, and crash location) are
recorded. However, other parties, such as
law enforcement, could combine the EDR
data with the type of personally identifying
data routinely acquired during a crash inves -
tigation.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer, other parties, such
as law enforcement, that have the special
equipment, can read the information if they
have access to the vehicle or the EDR.
Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function properly
if modifications are made. Take your
vehicle to an authorized dealer for any air
bag system service. If your seat,
including your trim cover and cushion,
needs to be serviced in any way
(including removal or loosening/tight -
ening of seat attachment bolts), take the
vehicle to an authorized dealer. Only
manufacturer approved seat accessories
may be used. If it is necessary to modify
the air bag system for persons with
disabilities, contact an authorized
dealer.

Exhaust GasThe 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, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust 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
webbing, etc.). If there is any question
regarding seat belt or retractor condition,
replace the seat belt.
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 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 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 autho
-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage
or in confined areas any longer than
needed to move your vehicle in or out of
the area.
If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the
climate control BLOWER switch is set at
high speed. DO NOT use the recircula-
tion mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force
outside air into the vehicle. Set the
blower at high speed.

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 acceler -
ator, 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!
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 fasteners 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
needs to be replaced, only use a FCA
approved floor mat for the specific make,
model, and year of your vehicle.
WARNING! (Continued)
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 accelerator,
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
