Synthetic Engine Oils
Your engine was designed for synthetic engine oils,
only use synthetic API approved engine oils.
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 addition 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 an
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
A full-flow type disposable oil filter should be used
for replacement. The quality of replacement filters
varies considerably. Only high quality Mopar®
certified filters should be used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals Úpage 190.
NOTE:Be sure to follow the Severe Duty Conditions main -
tenance interval if applicable Ú page 189.Engine Air Cleaner Filter Selection
The quality of replacement filters varies
considerably. Only high quality Mopar® certified
filters should be used.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
CAUTION!
Do not use chemical flushes in your engine oil as
the chemicals can damage your engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
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.
WARNING!
Use only refrigerants and compressor lubri
-
cants approved by FCA for your air condi -
tioning system. Some unapproved refrigerants
are flammable and can explode, injuring you.
Other unapproved refrigerants or lubricants
can cause the system to fail, requiring costly
repairs. Refer to Warranty Information Book,
for further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.

AUTOMATIC TRANSMISSION
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer specified
transmission fluid Úpage 241. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
Special Additives
It is strongly recommended against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product
and its performance may be impaired by
supplemental additives. Therefore, do not add any
fluid additives to the transmission. Avoid using
transmission sealers as they may adversely affect
seals.To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces; care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!
CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 241.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
