Cold Weather Operation
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than –22° F (–30° C)
and the oil temperature sensor reading indicates an
engine block heater has not been used. An externally-
powered electric engine block heater is available as
optional equipment or from your authorized dealer.
The message “plug in engine heater” will be displayed in
the instrument cluster when the ambient temperature is
below 5° F (–15° C) at the time the engine is shut off as a
reminder to avoid possible crank delays at the next cold
start.
CAUTION!
Use of the recommended SAE 5W-40 synthetic en-
gine oil and adhering to the prescribed oil change
intervals is important to prevent engine damage and
ensure satisfactory starting in cold conditions.
Extended Park Starting
NOTE:Extended Park condition occurs when the ve-
hicle has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery
to ensure a full battery charge during the crank cycle.
2. Place the ignition in the START position and release it
when the engine starts.

STARTING AND OPERATING 223

To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•Drain the fuel tank (see your authorized dealer.)
•Change the engine oil and oil filter.
•Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT (Methylcyclopentadienyl Manganese Tricarbonyl)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
272 STARTING AND OPERATING

Engine Oil
Checking Oil Level
To assure proper engine lubrication, 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 engine is shut off. Do not check oil level
before starting the engine after it has sat overnight.
Checking engine oil level when the engine is cold will
give you an incorrect reading.
Checking the oil while the vehicle is on level ground, and
about five minutes after a fully warmed engine is shut
off, will improve the accuracy of the oil level readings.
Maintain the oil level between the range markings on the
dipstick. The safe range is indicated by a crosshatch zone.
Adding 1 qt (1L) of oil when the reading is at the low end
of the indicated range will result in the oil level at the full
end of the indicator range.
CAUTION!
Do not overfill the engine with oil. Overfilling the
engine with oil will cause oil aeration, which can
lead to loss of oil pressure and an increase in oil
temperature. This loss of oil pressure and increased
oil temperature could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE: Under no circumstances should oil change in-
tervals exceed 10,000 miles (16,000 km) or twelve
months, whichever occurs first.
316 MAINTAINING YOUR VEHICLE

Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type dispos-
able oil filter. Use a filter of this type for replacement. The
quality of replacement filters varies considerably. Only
high quality filters should be used to assure most efficient
service. MOPAR® engine oil filters are high quality oil
filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR® engine air
cleaner filters are a high quality filter and are recom-
mended.
318 MAINTAINING YOUR VEHICLE

WARNING!(Continued)
must be exercised when filling or working around
the washer solution.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust 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, have the
exhaust system inspected each time the vehicle is raised
for lubrication or oil change. Replace as required.
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, refer to “Safety Tips/Exhaust Gas” in “Things
To Know Before Starting Your Vehicle” for further
information.
•A hot exhaust system can start a fire if you park
over materials that can burn. Such materials might
be grass or leaves coming into contact with your
exhaust system. Do not park or operate your ve-
hicle in areas where your exhaust system can con-
tact anything that can burn.

MAINTAINING YOUR VEHICLE 327

MAINTENANCE SCHEDULE
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 ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Change Oil” message is displayed.
Severe Operating 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
possible, within the next 500 miles (805 km).
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment. This
type of vehicle use is considered Severe Duty
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 reservoir, brake
master cylinder, and transmission as needed
•Check function of all interior and exterior lights
