6. Connect the other cable, first to the negative terminal
of the booster battery and then to the ground (on the ear
of the Thermostat Housing) of your Viper as shown.
Make sure you have a good contact.
7. If you are jump starting another vehicle, connect one
end of a jumper cable to the ground (on the ear of theThermostat Housing shown in illustration) of your Viper
and the other end to the engine of the other vehicle. Make
sure that you have a good contact on the engines.
NOTE:When using another vehicle as the power
source, turn off all accessories.
8. Turn off the Theft Security System.
NOTE:If system is not turned off, the Theft System
electronics will prevent the engine from starting.
9. Allow battery to charge to at least 12.4 volts before
attempting to start engine.
10. Start the engine in the booster vehicle and let the
engine idle for a few minutes. Then start the Viper
engine. If engine does not start in 15 seconds, stop
cranking engine and allow starter to cool down before
cranking again.
11. When removing the booster cables, reverse the above
sequence exactly.

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.

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.

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.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off the
