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.

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.

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.
NOTE:Also inspect the exhaust system if you notice a
change in the sound of the exhaust system, or if the
exhaust fumes can be detected inside the vehicle.
•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.
