REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is
located in the spare tire storage area. If your
vehicle is out of fuel and an auxiliary fuel can
is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.
For more information on the Cap-Less Fuel
System refer to “Refueling The Vehicle” in
“Starting And Operating ” in this manual.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place thetransmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes. NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the en-
gine cooling system and turning the A/C
off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop
the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer
drops back into the normal range. If the
pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully apply-
ing the parking brake, before activating
the Manual Park Release. Activating the
Manual Park Release will allow your ve-
hicle to roll away if it is not secured by the
parking brake or by proper connection to a
tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could
lead to serious injury or death for those in
or around the vehicle.

SCHEDULED SERVICING
NON-SRT
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe op-erating conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers. Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look
for unusual wear or damage.
• Check the fluid levels of the coolant reser- voir, brake master cylinder and fill as
needed.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the
following pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.SERVICING AND MAINTENANCE

Do not remove the cabin air filter while the
vehicle is running, or while the ignition is
in the ACC or ON/RUN mode. With the
cabin air filter removed and the blower
operating, the blower can contact hands
and may propel dirt and debris into your
eyes, resulting in personal injury.
The A/C air filter is located in the fresh air
inlet behind the glove compartment. Perform
the following procedure to replace the filter:
1. Open the glove compartment and remove all contents. 2. There are glove compartment travel stops
on both sides of the glove compartment
door, partially close the glove compart-
ment door and push inward to release the
glove compartment travel stop on one side
and repeat this procedure for the opposite
side. 3. Pull the right hand side of the glove com-
partment door toward the rear of the ve-
hicle to disengage the glove compartment
door from its hinges.

When disengaging the glove compartment
door from its hinges, there will be some
resistance.
4. With the glove compartment door loose, remove the glove compartment tension
tether and tether clip by sliding the clip
toward the face of the glove compartment
door and lifting the clip out of glove com-
partment door.
5. Remove the filter cover by disengaging the retaining tab and mid way snap that
secures the filter cover to the HVAC hous-
ing. Disengage the mid way snap by pull-
ing the door outward. Unhinge the filter
cover on the right side to fully remove the

Windshield Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner.
This will remove accumulations of salt or road
film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to remove frost
or ice from the windshield. Keep the blade
rubber out of contact with petroleum prod-
ucts such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
