Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.
T/A Air Filter Maintenance — If Equipped
Clean Engine Air Filter
The scheduled air filter cleaning interval is
30,000 miles (48,280 km), or if in a dusty
environment the engine air filter should be
checked periodically to ensure optimal air flow.
Cleaning your engine air filter with the
recommended Mopar Performance Air Filter
Service Kit is not required if you can still see any
part the wire screen on the entire air filter
regardless of how dirty it may appear. When any
part of the wire screen is no longer visible on the
air filter, that is an indication it is time to clean
the air filter.

1. Spray the air filter with the recommended
Mopar air filter cleaner and let sit for at
least 10 minutes to loosen dirt, before
rinsing.

NOTE:
Never use strong detergents, high pressure, or
gasoline on air filter. 2. Rinse the air filter with cool low-pressure
water applied from the inside (clean side)
out in order to flush the dirt out of the filter.
Continue to rinse the filter until all traces of
the cleaner have been removed.
NOTE:
It may be necessary to repeat steps 1 and 2 if
the air filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry
naturally. Do not apply oil until air filter is
completely dry.
NOTE:
Do not use forced air pressure as it may
damage the filtering capabilities of the filter’s
microfibers and also void its warranty.
4. Using the Mopar Performance Air Filter Service Kit, spray oil evenly along the crown
of each filter pleat holding the nozzle about
3 inches (76 mm) away from the air filter.
One spray per 2 square inches
(1,290 square mm) of air filter. With one
complete coat of oil, let it wick (saturate) for
about 20 minutes, and if required touch up
any light areas on either side of the filter.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.

268SERVICING AND MAINTENANCE
Fluid Level Check
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service
tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an
improper fluid level can cause severe
transmission damage.
Fluid And Filter Changes
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 contaminated (with water,
etc.), or if the transmission is disassembled for
any reason.
ALL WHEEL DRIVE (AWD) — IF
E
QUIPPED
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 case fluid 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 “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals.
REAR AXLE
Fluid Level Check
Checking the fluid level while the vehicle is on
level ground and has been stationary for
15 minutes will improve the accuracy of the
fluid level reading.
Check the fluid level by removing the fill plug on
the axle. The fluid level should be 1-2.5 mm
below the fill plug. Add fluid, if necessary, to
maintain the proper level. Refer to “Fluids And
Lubricants” in "Servicing And Maintenance” for
further information.CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.

Change Axle Fluid
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals.
NOTE:
For race track usage it is recommended that the
axle fluid be changed every 4 hours of on track
time.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.

NOTE:
P (Passenger) — Metric tire sizing is based on
US design standards. P-Metric tires have the
letter “P” molded into the sidewall preceding
the size designation.
Example: P215/65R15 95H.
European — Metric tire sizing is based on
European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based
on US design standards. The size designation
for LT-Metric tires is the same as for P-Metric
tires except for the letters “LT” that are
molded into the sidewall preceding the size
designation. Example: LT235/85R16.
Temporary spare tires are designed for
temporary emergency use only. Temporary
high pressure compact spare tires have the
letter “T” or “S” molded into the sidewall
preceding the size designation.
Example: T145/80D18 103M.
High flotation tire sizing is based on US
design standards and it begins with the tire
diameter molded into the sidewall.
Example: 31x10.5 R15 LT.

Tire Tread

These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an
inch (1.6 mm). When the tread is worn to the
tread wear indicators, the tire should be
replaced.
Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replace -
ment.
Distance driven.
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is
highly recommended. NOTE:
Wheel valve stem must be replaced as well
when installing new tires due to wear and tear
in existing tires.
Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance
of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear
Indicators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
See the Tire Sizing Chart example found in the
“Tire Safety Information” section of this manual
for more information relating to the Load Index
and Speed Symbol of a tire.
1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can result
in sudden tire failure. You could lose control
and have a collision resulting in serious injury
or death.

TIRE CHAINS AND TRACTION DEVICES —
SRT
Due to limited clearance, tire chains or traction
devices are not recommended.
TIRE ROTATION RECOMMENDATIONS —
N
ON-SRT
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. For
these reasons, they wear at unequal rates.
These effects can be reduced by timely rotation
of tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such
as those on all season type tires. Rotation will
increase tread life, help to maintain mud, snow
and wet traction levels, and contribute to a
smooth, quiet ride.
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals. The reasons for any rapid or unusual wear
should be corrected prior to rotation being
performed.
The suggested rotation method is the “rearward
cross” shown in the following diagram. This
rotation pattern does not apply to some
directional tires that must not be reversed.
