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.
IN CASE OF EMERGENCY
224

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
232

SCHEDULED SERVICING –
SRT
The Scheduled Maintenance services listed in
this manual must be done at the times or mile-
ages specified to protect your vehicle warranty
and ensure the best vehicle performance and
reliability. More frequent maintenance may be
needed for vehicles in severe operating condi-
tions, such as dusty areas and very short trip
driving. Inspection and service should also be
done anytime a malfunction is suspected.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
The Instrument Cluster Display will display
an “Oil Change Required” message and a
single chime will sound, indicating that an oil
change is necessary.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
NOTE:
• The oil change indicator message will notmonitor the time since the last oil change.
Change your vehicle's oil if it has been six
months since your last oil change, even if
the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you drive your vehicle off-road for an extended
period of time.
•
Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km) or
six months, whichever comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If a scheduled oil change is
performed by someone other than your autho-
rized dealer, the message can be reset by
referring to the steps described under “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in this guide.
At Each Stop For Fuel
• Check the engine oil level. Refer to “En- gine Compartment” in this section for fur-
ther information. • Check the windshield washer solvent and
add if required.
Once A Month
• Check tire pressure and look for unusual wear or damage.
• Inspect the battery, and clean and tighten the terminals as required.
• Check the fluid levels of the coolant reser- voir, engine oil, brake master cylinder, and
add as needed.
• Check all lights and other electrical items for correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required mainte-
nance items may result in damage to the
vehicle.

Checking Oil Level — Gasoline Engine
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best
time to check the engine oil level is about five
minutes after a fully warmed up engine is
shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Always maintain the oil level
within the SAFE zone on the dipstick. Adding
one quart of oil when the reading is at the
bottom of the SAFE zone will result in a
reading at the top of the safe zone on these
engines.
CAUTION!
Overfilling or underfilling the crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.
Checking Oil Level — Diesel Engine
To assure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level
is before starting the engine after it has been
parked overnight. When checking oil after
operating the engine, first ensure the engine
is at full operating temperature, then wait for
five minutes after engine shutdown to check
the oil.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Add oil only when the level on
the dipstick is below the “MIN” mark. The
total capacity from the MIN mark to the MAX
mark is 1.7 qts (1.6L).
CAUTION!
Overfilling or underfilling the crankcase
will cause oil aeration or loss of oil pres-
sure. This could damage your engine.NOTE:
It is possible for your oil level to be slightly
higher than a previous check. This would be
due to diesel fuel that may temporarily be in
the crankcase due to operation of the diesel
particulate filter regeneration strategy. This
fuel will evaporate out under normal opera-
tion.
Never operate the engine with oil level below
the “MIN” mark or above the upper “MAX”
mark.
Adding Washer Fluid
The instrument cluster display will indicate
when the washer fluid level is low. When the
sensor detects a low fluid level, the wind-
shield will light on the vehicle graphic outline
and the “WASHER FLUID LOW” message
will be displayed.
The fluid reservoir for the windshield washers
and the rear window washer is shared. The
fluid reservoir is located in the engine com-
partment, be sure to check the fluid level at
regular intervals. Fill the reservoir with wind-
shield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reser-
