WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
an accident resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.

All power steering pumps have a dipstick. Fluid level
should be maintained at the proper level indicated on the
dipstick. If necessary, add fluid to restore to the proper
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 otherunderhood 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 MoparLock
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.

Transmission
Lubricant Selection
Refer to the Recommended Fluids, Lubricants and Genu-
ine Parts section for correct fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality. Refer to the Recom-
mended Fluids, Lubricants and Genuine Parts sec-
tion for correct fluid type.
Fluid Level Check
The fluid in the transmission should be checked when-
ever other underhood services are done. Check the fluid
level by removing the fill plug located on the left side ofthe 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 fluid

Headlight Aiming
The headlights on your new Viper were aimed at the
factory. The factory setting was made at a no load setting.
A great increase in weight will change the aiming and it
may be necessary to readjust the headlights if you
typically carry an excessive amount of weight in the
trunk or otherwise suspect misalignment.
Aiming Check
Each headlight assembly can be adjusted up and down
only. No left to right adjustment is necessary. To check,
proceed as follows:
1. Fill the fuel tank and park the vehicle on level ground.
A driveway is not normally level. If in doubt and you
have no way to check levelness, do not attempt to adjust
the headlights.
2.
Mark the position of the headlights on a wall prior to
loading the vehicle. Load the trunk with the items you
normally carry. Have someone sit in the driver’s seat who is
about the same weight as the person who drives the vehicle.
3. Push down on the front and rear of the vehicle several
times to make sure that the suspension has settled.
4. Then readjust the headlights to the original position.
NOTE:If any further adjustments are necessary, contact
your dealership.

At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the suspension components.
•Lubricate door hinges and check springs.
•Check the engine coolant level, hoses, and clamps.
•Check power steering fluid level.
