CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.
If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
If the gas cap is not secured properly, the light may come
on. Be sure the gas cap is tightened every time you add
fuel.
High Beam Indicator
This light shows that the headlights are on high
beam. Pull the turn signal lever toward the steer-
ing wheel to switch the headlights from high or low
beam.
Seat Belt Indicator Light
This system alerts the driver to fasten the seat belt
if not done so within 60 seconds of starting the
vehicle and if the vehicle is moving faster than 5
mph (8 km/h). The system will cause a chime to sound
repeatedly and will flash the seat belt warning light for 96
seconds or until the driver’s seat belt is fastened. The
reminder system will be reactivated if the driver’s seat
belt is unfastened for more than 10 seconds and the
vehicle speed is greater than 5 mph (8 km/hr). Refer to
Enhanced Seat Belt Use Reminder System (BeltAlert™)in
the Occupant Restraints section for deactivating the
system.

WARNING!
Remove the fuel tank filler tube cap (gas cap) slowly
to prevent fuel spray from the filler neck that may
cause injury. The volatility of some gasolines may
cause a buildup of pressure in the fuel tank that may
increase while you drive the vehicle. This pressure
can result in a spray of gasoline and/or vapors when
you remove the cap from a hot vehicle. Removing the
cap slowly allows the pressure to vent and prevents
fuel spray. Never have any smoking materials lit in
or near the vehicle when the fuel tank filler tube cap
(gas cap) is removed or when filling the tank. Never
fill the gas tank while the engine is running.

146 STARTING AND OPERATING

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This system
monitors the performance of the emissions and engine
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light. It will also
store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be driveable and not need towing,
see your dealer for service as soon as possible.CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.
If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
If the gas cap is not tightened properly, the light may
come on. Be sure the gas cap is tightened every time you
add fuel.

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake, Power Steering, and Fuel System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasion, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be made to examining those hose sur-
faces nearest to high heat sources, such as the exhaust
manifold.Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Insure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids are used during assembly plant
operations to ease the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation) should be noted before hose is re-
placed based on leakage.
High pressure fuel system hoses have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
Use only manufacturer specified hoses or their equiva-
lent in material and specification, in any fuel system

Headlight Aiming
The headlights on your new Viper were aimed at the
factory. The factory setting was made at a no load setting.
A great increase in weight will change the aiming and it
may be necessary to readjust the headlights if you
typically carry an excessive amount of weight in the
trunk or otherwise suspect misalignment.
Aiming Check
Each headlight assembly can be adjusted up and down
only. No left to right adjustment is necessary. To check,
proceed as follows:
1. Fill the fuel tank and park the vehicle on level ground.
A driveway is not normally level. If in doubt and you
have no way to check levelness, do not attempt to adjust
the headlights.
2.
Mark the position of the headlights on a wall prior to
loading the vehicle. Load the trunk with the items you
normally carry. Have someone sit in the driver’s seat who is
about the same weight as the person who drives the vehicle.
3. Push down on the front and rear of the vehicle several
times to make sure that the suspension has settled.
4. Then readjust the headlights to the original position.
NOTE:If any further adjustments are necessary, contact
your dealership.
