FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:On vehicles so equipped the radio, steering
wheel radio controls and 6 disc CD/DVD changer will
remain active for up to 45 seconds after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

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.

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

level 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.
