TIRE CHAINS
Due to limited clearance, tire chains are not recom-
mended.
CAUTION!
Damage to the vehicle may result if tire chains are
used.
SNOW TIRES
There are no snow tires that are compatible with the
wheels on this vehicle.
Tire Storage
Tire storage is addressed in the Michelin Limited Tire
Warranty Booklet.
Specific recommendations on guidelines for long term
tire storage for this vehicle should be requested of the
Michelin Tire Corporation 1-800-433-6838.
Tire Rotation Recommendations
Do not rotate these tires as the wider rear tires will not fit
on the front of the vehicle.
Your vehicle has tires with directional tread, which will
also not allow switching tires from side to side.

DRIVING ON SLIPPERY SURFACES
WARNING!
Rapid acceleration on slippery surfaces is danger-
ous. You could lose control of the vehicle and possi-
bly have an accident. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
•Slow down during rainstorms or when roads are
slushy.
•Slow down if road has standing water or puddles.
CAUTION!
Driving your Viper through deep puddles at speeds
over 5 mph, may cause water to be ingested into the
engine. This can cause severe engine damage.
•Replace tires when tread wear indicators first become
visible.
•Keep tires properly inflated.
•Maintain enough distance between your vehicle and
the vehicle in front to avoid a collision in a sudden
stop.
162 WHAT TO DO IN EMERGENCIES
Page 163 of 264
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverse
and First gear. Usually the least accelerator pedal pres-
sure to maintain the rocking motion without spinning the
wheels is most effective.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).
TOWING A DISABLED VEHICLE
Do not tow with sling type equipment. Only use flat bed
equipment. Always comply with applicable state or local
towing ordinances.
CAUTION!
Towing with equipment other than flat bed types
may damage your vehicle.

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.
FUSES — Power Distribution Center
A power distribution center is located in the engine
compartment. This center contains fuses and relays.

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.

TIRE QUALITY GRADES
The following describes the tire grading categories estab-
lished by the National highway Traffic Safety Adminis-
tration. The specific grade rating assigned by the tire’s
manufacturer in each category is shown on the sidewall
of the tires on your car.All Passenger Car Tires Must Conform to Federal Safety
Requirements in Addition to These Grades.
Treadwear
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled con-
ditions on a specified government test course. For ex-
ample, a tire graded 150 would wear one and a half (1
1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.

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.
