Operating TipsA/C Air Filter— If Equipped
On vehicles equipped with Automatic Temperature Con-
trol (ATC), the climate control system filters out dust and
pollen from the air. Refer to “Air Conditioning” in
“Maintaining Your Vehicle” for filter replacement
instructions.

The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE:
•Check the automatic transmission fluid level before
towing.
•The six-speed automatic transmission is sealed and
requires an authorized dealer to check the transmis-
sion fluid.
Electronic Speed Control – If Equipped
•
Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
•Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
•City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL but do not increase engine idle
speed.
•Highway Driving
Reduce speed.
•Air Conditioning
Turn off temporarily.

Engine Oil Viscosity (SAE Grade) – 3.3L & 3.8L
Gasoline Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
“Engine Compartment” in “Maintaining Your Vehicle”
for further information.
Lubricants that do not have both the engine oil certifica-
tion mark and the correct SAE viscosity grade number,
should not be used.
Engine Oil Viscosity (SAE Grade) – 4.0L Gasoline
Engines
SAE 10W-30 engine oil is preferred for all operating
temperatures. Your engine oil filler cap also shows the
recommended engine oil viscosity for your vehicle.For information on engine oil filler cap location, refer to
“Engine Compartment” in “Maintaining Your Vehicle”
for further information.
Lubricants that do not have both the engine oil certifica-
tion mark and the correct SAE viscosity grade number,
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental
additives.7

Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type 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. MOPARengine oil filters are a high quality oil
filter and are recommended.
Engine Air Cleaner Filter
Refer to “Maintenance Schedule” for the proper mainte-
nance 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 recommended.
