The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during angled
or offset frontal collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
NOTE:Air bag covers may not be obvious in the interior trim, but
they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are designed to
activate in certain rollover events. The Occupant Restraint
Controller (ORC) determines whether deployment in a
particular rollover event is appropriate, based on the
severity and type of collision. Vehicle damage by itself is
not a good indicator of whether or not Side Air Bags and
seat belt pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners 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. In the event the vehicle experiences a rollover or near
rollover event, and deployment is appropriate, the rollover
sensing system will deploy the side air bags and seat belt
pretensioners on both sides of the vehicle.
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
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Occupant Classification SystemWARNING!
Occupants, including children, who are up against or
very close to Side Air Bags can be seriously injured or
killed. Occupants, including children, should never
lean on or sleep against the door, side windows, or
area where the side air bags inflate, even if they are
in an infant or child restraint.
Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection from
the Side Air Bags, occupants must wear their seat
belts properly and sit upright with their backs against
the seats. Children must be properly restrained in a
child restraint or booster seat that is appropriate for
the size of the child.
WARNING!
Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat.
Being too close to the Side Air Bags during deploy -
ment could cause you to be severely injured or killed.
Relying on the Side Air Bags alone could lead to more
severe injuries in a collision. The Side Air Bags work
with your seat belt to restrain you properly. In some
collisions, Side Air Bags won’t deploy at all. Always
wear your seat belt even though you have Side
Air Bags.

SAFETY297
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 signifi -
cantly 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 irrita -
tion, 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 instruc -
tions 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 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 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 inter -
vention of the Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC Blower
Motor, Close the HVAC Circulation Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlight washer pump (if equipped)
NOTE:After an accident, remember to cycle the ignition to the
STOP (OFF/LOCK) position and remove the key from the
ignition switch to avoid draining the battery. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
If there are no fuel leaks or damage to the vehicle elec -
trical devices (e.g. headlights) after an accident, reset the
system by following the procedure described below. If you
have any doubt, contact an authorized dealer.
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.

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
Úpage 282 for further information.

cles 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 collision, 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.
WARNING!
It is not possible to know or to predict all of the possible
outcomes if your vehicle’s systems are breached. It may
be possible that vehicle systems, including safety
related systems, could be impaired or a loss of vehicle
control could occur that may result in an accident

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.
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE 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 lug nut/bolt torque for tightness. Check the
tires (including spare) for proper cold inflation pressure.
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.
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 acceler -
ator, 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.
WARNING!
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

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.
EXHAUST GAS
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 an authorized dealer 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.
CARBON MONOXIDE WARNINGS
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 recirculation 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.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.

SERVICING AND MAINTENANCE341
PRESSURE WASHING
Cleaning the engine compartment with a high pressure
washer is not recommended.
VEHICLE MAINTENANCE
An authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.

void your warranty and could result in civil penalties being
assessed against you.
ENGINE OIL
Engine Oil Selection
Use only the manufacturer's recommended fluids Úpage 396.
NOTE:Hemi engines (5.7L) at times can tick right after startup
and then quiet down after approximately 30 seconds. This
is normal and will not harm the engine. This characteristic
can be caused by short drive cycles. For example, if the
vehicle is started then shut off after driving a short
distance. Upon restarting, you may experience a ticking
sound. Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended oil
changes or extended idling. If the engine continues to tick
or if the Malfunction Indicator Light (MIL) comes on, see
the nearest authorized dealer.
American Petroleum Institute (API)
Approved Engine Oil
These symbols mean that the oil has been certified by the
API. The manufacturer only recommends API trademark
oils.
The API Starburst trademark certifies 0W-20,
0W-30 and 5W-30 engine oils.
The API Donut trademark certifies 0W-40 and
5W-40 engine oil.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the posi -
tive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
