WARNING!
• Side Air Bags need room to inflate. Do not lean against the door or window. Situpright in the center of the seat.
• Being too close to the Side Air Bags during deployment 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.
• This vehicle is equipped with left and right Supplemental Side Air Bag
Inflatable Curtains (SABICs). Do not stack luggage or other cargo up high
enough to block the deployment of the SABICs. The trim covering above the
side windows where the SABIC and its deployment path are located should
remain free from any obstructions.
• This vehicle is equipped with SABICs. In order for the SABICs to work as
intended, do not install any accessory items in your vehicle which could alter
the roof. Do not add an aftermarket sunroof to your vehicle. Do not add roof
racks that require permanent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the vehicle for any reason.
• Do not use accessory seat covers or place objects between you and the Side Air
Bags; the performance could be adversely affected and/or objects could be
pushed into you, causing serious injury.
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.
• Flash hazard lights as long as the battery has power or until the hazard light button
is pushed. The hazard lights can be deactivated by pushing the hazard light
button.
• Turn on the interior lights, which remain on as long as the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset Procedure
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.

Air Bag Warning Light
The air bags must be ready to inflate for your protection in a collision. The Occupant
Restraint Controller (ORC) monitors the internal circuits and interconnecting wiring
associated with air bag system electrical components.
The 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 turns on the Air Bag Warning Light in the instrument panel for approxi-
mately four to eight seconds for a self-check when the ignition switch is first turned
to 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.
If the Air Bag Warning Light in the instrument panel is not on during the four to eight
seconds when the ignition switch is first turned to the ON/RUN position, stays on, or
turns on while driving, have the vehicle serviced by an authorized service center
immediately.
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.
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.

ENGINE BREAK-IN RECOMMENDATIONS
3.6L Engine Break-In
For vehicles equipped with the 3.6L, 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 “Maintenance
Procedures” in “Maintaining Your Vehicle”.
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.
5.7L Engine Break-In
For vehicles equipped with the 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.

oil indicator often during the break in period. Add oil as required.
6.4L Engine Break-In
For vehicles equipped with the 6.4L use the following engine break-in recommendations:
Despite modern technology and World Class manufacturing methods, the moving
parts of the vehicle must still wear in with each other. This wearing in occurs mainly
during the first 500 miles (805 km) and continues through the first oil change
interval.
It is recommended for the operator to observe the following driving behaviors during
the new vehicle break-in period:
0 to 100 miles (0 to 160 km):
• Do not allow the engine to operate at idle for an extended period of time.
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid acceleration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.
100 to 300 miles (160 to 483 km):
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid acceleration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.
• Drive with the engine speed less than 5,000 RPM.
• Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting manually (paddles or gear shift) at higher rpms when possible.
• Do not perform sustained operation with the accelerator pedal at wide open throttle.
• Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.
OPERATING YOUR VEHICLE

For the first 1500 miles (2414 km):
• Do not participate in track events, sport driving schools, or similar activities duringthe first 1500 miles (2414 km).
NOTE:
Check engine oil with every refueling and add if necessary. Oil and fuel consumption
may be higher through the first oil change interval.
HEADLIGHT SWITCH
The headlight switch is located on the left side of the instrument panel, next to the
steering wheel. The headlight switch controls the operation of the headlights, parking
lights, instrument panel lights, cargo lights and fog lights (if equipped).
To turn on the headlights, rotate the
headlight switch clockwise. When the
headlight switch is on, the parking lights,
taillights, license plate light and instru-
ment panel lights are also turned on. To
turn off the headlights, rotate the head-
light switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass
lights. Plastic is not as scratch resis-
tant as glass and therefore different
lens cleaning procedures must be fol-
lowed.
• To minimize the possibility of scratch- ing the lenses and reducing light out-
put, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild
soap solution followed by rinsing.
CAUTION!
Do not use abrasive cleaning components, solvents, steel wool or other abrasive
materials to clean the lenses.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significantweight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a high-quality energy
conserving type lubricant. Oil changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
