•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
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles 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.
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 assem-
blies replaced by an authorized dealer immediately.
Also, have the Occupant Restraint Controller System
serviced as well. 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 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.
168 SAFETY

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)

SAFETY 169

Exhaust Gas
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 even-
tually 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 con-
trols to force outside air into the vehicle. Set the
blower at high speed.
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 a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust 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 web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill 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,

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 accelera-
tor, 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.
(Continued)
WARNING! (Continued)
•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 Make 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 wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.

from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
(Continued)
WARNING! (Continued)
•If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery
or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to “Jump
Starting Procedure” in “In Case Of Emergency” for
further information.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.

STARTING AND OPERATING 199

The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that is
located near the air box.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS
For vehicles equipped with the 3.6L or 5.7L use the
following engine break-in recommendations:
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. For the recommended
viscosity and quality grades, refer to “Fluids And Lubri-
cants” in “Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as an indication of difficulty. Please check your
oil level with the engine oil indicator often during the
break in period. Add oil as required.
For vehicles equipped with the 6.4L use the following
engine break-in recommendations:
Despite modern technology and World Class manufactur-
ing methods, the moving parts of the vehicle must still
