HAZARD WARNING FLASHER
The flasher switch is on the top of the steering
column, just behind the steering wheel. Depress
the flasher button and all front and rear directional
signals will flash. Depress the flasher button again to turn
the flashers off.Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed.
NOTE:With extended use, the flasher may run down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways —Slow down and use the highest
gear possible.
•In city traffic —While stopped, put the transmission
in neutral, but do not increase engine idle speed.

NOTE:Remove the floor portion of the rear compart-
ment carpet to gain access to the battery.
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach but
without letting the vehicles touch. Set the parking brake,
place the transmission in neutral and turn the ignition
OFF for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.
4. If you are jump starting your Viper, connect one end of
a jumper cable to the positive terminal of the booster
battery. Connect the other end of the same cable to the
remote battery positive terminal after removing the plas-
tic cover.
5. If you are jump starting another vehicle, connect one
end of a jumper cable to the remote battery positive
terminal post on the Power Distribution Center. Connect
the other end of the same cable to the positive terminal of
the discharged battery after removing the plastic cover.

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.

To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected for prolonged period.
Ignition Wiring System and Ignition Timing
The ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Do not
remove the nipple assemblies from the coil towers unless
the nipples are damaged or cable testing shows high
resistance or broken insulation. Refer to the ServiceManual for the proper procedure to be followed for
checking ignition cable resistance. Cracked, damaged, or
faulty cables should be replaced.
Because of the plastic body shell on your Viper, ignition
cables should be replaced with the specially designed RFI
cables available at your dealer.
Ignition timing cannot be set on this vehicle.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from plugging due to deposits. As vehicle mileage builds
up, the Crankcase Ventilation Valve orifice may accumu-
late deposits. If a valve is not working properly, replace it
with a new orifice. DO NOT ATTEMPT TO CLEAN THE
OLD ORIFICE!
Check the ventilation hose for indication of damage or
plugging deposits. Replace if necessary.

Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.
Hydraulic Clutch
The fluid in the clutch master cylinder should be checked
when performing other under hood services. To check
the fluid level, remove the reservoir cap. If necessary, add
fluid to the reservoir. Use only the manufacturer’s rec-
ommended brake fluid. Refer to the Recommended Flu-
ids, Lubricants and Genuine Parts section for the correct
fluid type. Mopar brake fluid or equivalent is fluid of this
quality and is recommended to provide best brake per-
formance. Make sure that the fluid has been stored in a
tightly closed container to avoid contamination with dirt
or moisture. Do Not Overfill. Overfilling can cause clutch
release problems as the clutch wears. A low fluid level
may indicate a leak, in which case, hydraulic clutch
linkage replacement may be required. The fluid level in
the reservoir will rise as the clutch wears - Do Not
Remove Fluid.Do not allow petroleum base fluid to contaminate the
brake fluid — seal damage will result.
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 of
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 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.
