Convertible Top Care — Convertible Models Only
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 youremove 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.

Check the battery every 4 to 6 weeks to ensure that the
voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below
12.40, follow the battery recharge procedure in the
Service Manual.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Block the wheels. Do not apply the Parking Brake.
•Make sure that all tires are inflated to the optimum
pressure, (29 PSI).
•Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
•For long term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
•Move the wiper blades away from the windshield.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the trunk/liftgate, hood, doors, win-
dows and convertible top are completely closed.
2. Make sure that remote transmitter is operating and
that the battery is good.
3. Make sure that the hood, trunk/liftgate and door
switches are in adjustment. Perform the quick system
check which follows.
Use the remote transmitter to set the alarm. If the alarm
SET light comes on and flashes, the system is operating
properly. If not, there is a problem with a switch or the
system. See your dealer for service.

Traction Grades
The traction grades, from highest to lowest, are A, B, and C,
and they represent the tire’s ability to stop on wet pave-
ment as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
WARNING!
The traction grade is based on braking (straight-
ahead) traction tests and does not include cornering
(turning) performance.
Temperature Grades
The temperature grades are A (highest), B, and C, repre-
senting the tire’s resistance to the generation of heat and
its ability to dissipate heat when tested under controlled
conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of thetire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance which all passen-
ger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory test wheel
than the minimum required by law.
WARNING!
The temperature grade is established for a tire that is
properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup
and possible tire failure.
