276SAFETY
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
NOTE:After an accident, remember to cycle the ignition to the
START or ON/OFF 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.
Enhanced Accident Response System
Reset Procedure
If applicable, refer to the “Hybrid Supplement” for
additional information.
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
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.
After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must be
towed to an authorized dealer to be inspected and to have
the Enhanced Accident Response System reset.
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

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. This light will illuminate with a single chime when
a fault with the Air Bag Warning Light 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 261 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
pedal assemblies. 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 pedal assemblies 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.

 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.
 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
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.
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 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!
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.
 When exiting the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle and lock your vehicle.

DRAINING FUEL/WATER SEPARATOR
F
ILTER — DIESEL ENGINE
The fuel/water separator housing is located inside the left
frame rail in front of the fuel tank. The best access to this
water drain valve is from under the vehicle.
If necessary remove the fuel filter protective cover to
access the water drain valve.

Fuel/Water Separator Filter

If water is detected in the water separator while the engine
is running, or while the ignition switch is in the ON position,
the Water In Fuel Indicator Light will illuminate and an
audible chime will be heard. At this point you should stop
the engine and drain the water from the filter housing.

Fuel/Water Separator Filter

Within 10 minutes of vehicle shutdown, turn the filter
drain valve (located on the bottom of the filter housing)
counterclockwise to drain fuel/water; allow the
accumulated water to drain. Leave the drain valve open
until all water and contaminants have been removed.
When clear fuel is visible, close the drain valve by turning
it clockwise.
Upon proper draining of the water from fuel filter
assembly, the Water In Fuel Indicator Light will remain
illuminated for approximately 10 seconds. If the water was
drained while the engine was running, the Water In Fuel
Indicator Light may remain on for approximately three
minutes.
NOTE:Care should be taken in disposing of used fluids from your
vehicle. Used fluids, indiscriminately discarded, can
present a problem to the environment. Contact an autho-
rized dealer, service station, or government agency for
advice on recycling programs and for where used fluids
and filters can be properly disposed of in your area.
If more than two ounces or 60 ml of fuel have been
drained, follow the directions for Priming If The Engine Has
Run Out Of Fuel
Úpage 323.

SERVICING AND MAINTENANCE331
(Continued)
With the engine OFF and cold, the level of the engine
coolant should be within the OK range between the ADD
and FULL range on the dipstick.

1. Remove the cap with level dipstick from the engine
coolant bottle.

2. Clean off the coolant from the dipstick.
3. Rest the cap on the opening of the coolant bottle without tightening the cap.
4. Remove the cap with dipstick and check the coolant level on the dipstick.
The radiator normally remains completely full, so there is
no need to remove the radiator/coolant pressure cap
unless checking for engine coolant freeze point or
replacing coolant. Advise your service attendant of this. As
long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant is needed to maintain the
proper level, only OAT coolant that meets the
requirements of the manufacturer Material Standard
MS.90032 should be added to the coolant bottle. Do not
overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilometers
of operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to enter
the radiator. If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.

Do not overfill the coolant expansion bottle.
 Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant needs
to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
 If frequent engine coolant additions are required, the
cooling system should be pressure tested for leaks.
 Maintain engine coolant concentration at a minimum
of 50% OAT coolant (conforming to MS.90032) and
distilled water for proper corrosion protection of your
engine which contains aluminum components.
 Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
 Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
 Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically. For
the proper maintenance intervals
Úpage 307.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
Brake System Warning Light is on. If necessary, add fluid
to bring level within the designated marks on the side of
the reservoir of the brake master cylinder. Be sure to clean
the top of the master cylinder area before removing cap.
With disc brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be checked
when pads are replaced. If the brake fluid is abnormally
low, check the system for leaks
Úpage 376.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on the
brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
WARNING!
Use only the manufacturer recommended brake fluid Úpage 376. Using the wrong type of brake fluid can
severely damage your brake system and/or impair its
performance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
