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.
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
quality filters should be used to assure most efficient
service. MOPAR® engine oil filters are a high quality oil
filter and are recommended.

WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
(Continued)
WARNING!(Continued)
•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 a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed 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.

NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials
1500 Model rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) MOPAR® Limited
Slip Additive be added to the gear lubricant. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information. The MOPAR®
Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made to an axle
equipped with a Limited Slip Differential.
2500/3500 Model axlesDO NOT REQUIREany limited
slip oil additive (friction modifiers).
NOTE:When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive), the
Limited Slip Additive should be added before the gear
lubricant is added to insure proper additive fill.
Transfer Case
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.

and MOPAR® Total Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid. Please
do not use polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia-based cleaners to clean your leather
upholstery. Application of a leather conditioner is not
required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.
CAUTION!
Do not use Alcohol and Alcohol-based and/or Keton
based cleaning products to clean leather seats, as
damage to the seat may result.
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone break-
age than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR® Glass Cleaner, or any commercial
household-type glass cleaner. Never use an abrasive type

WARNING!
Do not use silicon-based protection products to clean
your bedliner. Silicon-based products can become
slippery and may result in personal injury.
Spray-On Bedliners are chemically-resistant to many
different types of chemicals (including gasoline, oil,
hydraulic fluids) for short periods of time. If a spill
occurs on your Spray-On Bedliner, rinse the truck out as
soon as possible to avoid permanent damage.
Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage a
Spray-On Bedliner. One common condition is when
loading a heavy pallet and dragging that pallet across the
floor of the bed. If a nail or sharp point is exposed under
the weight of the pallet a scratch or tear is possible. While
not covered by your new vehicle warranty, a cosmetic fix
to cover the metal exposed by the scratch is required. To
repair a tear or gouge, follow the directions provided in
the MOPAR® Quick Repair Kit.
FUSES
WARNING!
•When replacing a blown fuse, always use an ap-
propriate replacement fuse with the same amp
rating as the original fuse. Never replace a fuse
with another fuse of higher amp rating. Never
replace a blown fuse with metal wires or any other
material. Failure to use proper fuses may result in
serious personal injury, fire and/or property dam-
age.

with your fingers or by allowing it to contact other
oily surfaces. Shortened bulb life will result.
•Always use the correct bulb size and type for
replacement. An incorrect bulb size or type may
overheat and cause damage to the lamp, the bulb
socket, or the lamp wiring.
NOTE:There are access covers over both headlamp bulb
access holes in the quad front lamp unit housing (if
equipped). These covers MUST be reinstalled after the
bulb has been replaced.
