Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In Winter months make sure the air intake is
clear of ice, slush and snow.
A/C Air Filter
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be totally
filtered out. Refer to “Maintenances Procedure” in “Main-
taining Your Vehicle” for filter replacement instructions.

Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion 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.
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 sta-
tion 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
This 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 qualityfilters 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 main-
tenance 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 ve-
hicle 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.

Refrigerant Recovery And Recycling R134a — If
Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Refrigerant Recovery And Recycling R1234yf — If
Equipped
R-1234yf Air Conditioning Refrigerant is a hydrofluoole-
fine HFO that is endorsed by the Environmental Protection
Agency and is an ozone-saving product with a low GWP
(Global Warming Potential). However, the manufacturer
recommends that air conditioning service be performed by
authorized dealer or other service facilities using recovery
and recycling equipment.
NOTE: Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
A/C Air Filter
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger side
of the vehicle, next to the windshield wipers. When install-
ing a new filter, ensure its proper orientation.
1. Remove the access door in the cowl screen by pressing the retaining clips.

2. Unsnap both ends and lift the filter access cover.
3. Remove the used filter.
4. Install the new filter with arrows pointing in the direc-tion of airflow, which is toward the rear of the vehicle
(text and arrows on the filter will indicate this). 5. Close the filter access cover.
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.

CAUTION!
If a transmission fluid leak occurs, visit your autho-
rized dealer immediately. Severe transmission damage
may occur. Your authorized dealer has the proper tools
to adjust the fluid level accurately.
Fluid And Filter Changes — 8 Speed Transmission
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contami-
nated (with water, etc.), or if the transmission is disas-
sembled for any reason.
All Wheel Drive (AWD) — If Equipped
The all wheel drive system consists of a transfer case and
front differential. The exterior surface of these components
should be inspected for evidence of fluid leaks. Confirmed
leaks should be repaired as soon as possible.
The transfer case fluid fill/inspection plug is located in the
middle of the rear housing. To inspect the transfer casefluid level, remove the fill/inspection plug. The fluid level
should be even with the bottom of the hole. Use this plug
to add fluid as required.
The front differential fill plug is located on the outer cover
near the halfshaft attachment. To inspect the differential
fluid level, remove the fill plug. The fluid level should be
even with or slightly below the bottom of the hole.
Fluid Changes
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Rear Axle
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids, Lubricants, And Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Fluid Level Check
Check the fluid level by removing the fill plug on the axle.
The fluid level should be at the bottom of the fill hole. Add
