indicated level. With a clean cloth, wipe any spilled fluid
from all surfaces. Only petroleum fluids specially formu-
lated for minimum effect on the rubber hoses should be
used. Use only the manufacturer's recommended fluid.
Refer to Recommended Fluids, Lubricants and Genuine
Parts for the correct fluid type.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, liftgate and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as MopartLock
Cylinder Lubricant directly into the lock cylinder.
Front and Rear Suspension Ball Joints
Your vehicle has suspension ball joints that require
periodic servicing. These ball joints should be inspected
whenever servicing a vehicle for other reasons.
Damaged seals should be replaced to prevent leakage or
contamination of the grease. If there is any movement
within the ball joint, the knuckle or control arm must be
replaced. The ball joints are not serviceable by them-
selves.
Relubrication
Ball joints are lubricated at the factory with a special
grease. They should be regreased at intervals as specified
in the maintenance schedules. When lubricating ball

Cooling System
WARNING!
You or others can be badly burned by hot coolant or
steam from your radiator. If you see or hear steam
coming from under the hood, don't open the hood
until the radiator has had time to cool. Never try to
open a cooling system pressure cap when the radia-
tor is hot.
Inspection
Coolant protection checks should be made every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check the front of the radiator for any accumu-
lation of bugs, leaves, etc.Check the coolant bottle tubing for condition and tight-
ness of connection at reserve tank and radiator. Inspect
the entire system for leaks.
NOTE:Check the front of the radiator for debris (leaves,
paper, etc.) regularly. A build up of such material could
lead to engine overheating.
Do not remove the cooling system pressure cap when the
cooling system is hot.
Cooling System Ð Drain, Flush and Refill
The cooling system should be drained, flushed and
refilled at the intervals shown on the Maintenance Sched-
ules.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals. Discard old antifreeze
solution according to recommended procedure.

hose routing to be sure hoses do not touch any heat
source or moving component that may cause heat dam-
age or mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of degradation that could result in failure.
Brake System
To assure brake system performance, all brake system
components should be inspected periodically. Suggested
service intervals can be found in Section 8 of this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
Brake, Power Steering, and Fuel System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasion, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be made to examining those hose sur-
faces nearest to high heat sources, such as the exhaust
manifold.

the transmission. The fluid level should be at the bottom
of the fill hole. Add fluid, if necessary, to maintain the
proper level.
Frequency of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. If the vehicle is operated under severe
conditions, change the fluid as specified in Maintenance
ScheduleB. If contaminated with water, the fluid should
be changed immediately.
Rear Axle
Fluid Level Check
Every 12 months or 6,000 miles (10 000 km) the exterior of
the axle should be checked for evidence of gear oil
leakage. This check should be made with the vehicle in a
level position, supported by the suspension, on an axle
and wheel type hoist, or on the ground. The axle fluidlevel should be between the bottom of the filler plug and
a point approximately 3/8 inch (9.5mm) below the filler
plug.
Lubricant Selection
Use only the manufacturer's recommended transmission
fluid. Refer to the Recommended Fluids, Lubricants and
Genuine Parts section for correct fluid type. This Limited
Slip Differential requires that a friction control additive
be added to the gear oil whenever a fluid change is made.
Frequency of Oil Change
Drain and fill the axle at the interval specified in the
Maintenance Schedules. Change the fluid immediately if
contaminated with water.

Wheel Bearings
Your Viper has permanently sealed wheel bearings that
do not require periodic maintenance.
Appearance Care
Your manufacturer's dealer offers a complete line of
products for cleaning your Viper. Follow the instructions
on each container.
Leather or Vinyl Seat/Trim Care and Cleaning
Leather is best preserved by regular cleaning with a
damp soft cloth. Small particles of dirt can act as an
abrasive and damage the leather surface and should be
removed immediately with a damp cloth. Stubborn soils
can be removed easily with a soft cloth and Mopar Total
Clean. Care should be taken to avoid soaking the leather
with any liquid. Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia based cleaners
to clean the leather. Application of a leather conditioner is
not required to maintain the original condition.
Paint and Trim
Your vehicle is exposed to the corrosive effects of chemi-
cal fall out, salt spray, and road film. To protect not only
the paint and trim, but also exposed mountings and
fixtures, it is important you wash it often and thoroughly.
After washing, allow all surfaces to drain and dry before
parking in a closed garage. Prompt washing may not
thoroughly remove these deposits. Additional cleaners
may be required. When using chemical cleaners formu-
lated for this purpose, be certain they are safe for use on
urethane painted surfaces.
Use soap and water on dull black window trim. Polish or
cleaners may leave a white residue. If desired, you may
polish your vehicle immediately by using Mopar Auto-
mobile Polish.

Glass Surfaces
All glass surfaces should be cleaned regularly with any
commercial household-type glass cleaner. Never use an
abrasive type cleaner.
Cleaning Plastic Instrument Cluster Lenses
When cleaning the lenses, use care to avoid scratching
the plastic.
NOTE:Never scrape the windows with squeegees,
razor blades, or other sharp instruments.
²Clean with a wet soft rag. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If using soap, wipe clean with a clean damp
rag or chamois cloth.
²Dry with a soft tissue.
Damage to the Body Finish
Any stone chips, fractures or deep scratches in the finish
should be promptly repaired.Minor damage can be repaired by using touch-up mate-
rials available at your dealers. More extensive damage
should be corrected in your dealer's paint facility.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Convertible Top Care
Use a mild detergent to clean the top. Avoid heavy
scrubbing and rinse with plenty of clean water. Allow to
dry thoroughly before storage.

Carpeting
Vacuum your carpeting regularly to prevent a soil
buildup. Shampoo soiled carpeting with a reliable uphol-
stery cleaner, using a natural sponge or soft bristle brush.
After carpeting dries, vacuum it thoroughly.
Underbody Maintenance
The corrosive materials used for ice and snow removal or
dust control may accumulate on the underbody of your
vehicle. If not removed, these materials may accelerate
rusting and deterioration of underbody components such
as fuel lines, frame, floor pan, exhaust system, etc.
At least twice during the winter months hose down the
wheel wells and underside of the vehicle. Make sure you
remove mud and salt from panels, crevices and ledges,
and that all drain holes and channels are free of debris.
NOTE:You can do more harm by hosing off the vehicle
without removing caked mud and debris.
The frame of your Viper is galvanized for rust-through
protection. It is also dipped in a black E-Coat to protect the
welded areas. Avoid any scratches through to bare metal.
Commercial Car Washes
We do not recommend that you take your Viper through
a commercial car wash.
In the event that you do take your Viper to a commercial
car wash, move the Heater/Air Conditioning blower
control to the lowest setting. This will prevent the possi-
bility of water entering the system.
CAUTION!
The tires on your Viper are wider than the guide
tracks on most washes and the low ground clearance
of your vehicle may not be compatible with some car
wash equipment. You could damage your vehicle.

²If the vehicle will be subjected to freezing tempera-
tures, remove the battery and store it in a dry, well
ventilated area or place a trickle charger (1.5 Amp)
with automatic shutdown / overcharge protection
connected to the battery. Do not leave the trickle
charger hooked up to the battery without being
plugged into the 110 AC voltage outlet, because this
will result in further drain on the vehicle's battery. If
the vehicle is not going to be driven in the next 3
weeks, follow the battery recharge procedure in the
Service Manual, then disconnect the battery at the
negative terminal or use the save feature described in
Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery.CAUTION!
Use care when disconnecting the remote positive
cable. It is connected to the battery and can short out
to any metal on the vehicle. Always tape or wrap the
exposed cable end to prevent electrical shorts.
²Disconnecting the battery causes the engine control
system to lose memory of some ªlearnedº functions,
unless using the Battery Save feature described in
Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery. The engine may run rough when first
started after a battery disconnect until the control
module ªrelearnsº these functions.
