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.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 the
Ground Connection

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
162 MAINTAINING YOUR VEHICLE
Page 163 of 264

ignition key or start the engine. This means that your
vehicle’s OBD system isnot readyand you shouldnot
proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or start
the engine. This means that your vehicle’s OBD system
isreadyand you can proceed to the I/M station.
If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have yourvehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
REPLACEMENT PARTS
Use of genuine Moparparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Moparparts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
DEALER SERVICE
Your dealer has the qualified service personnel, special
tools and equipment to perform all service operations in
an expert manner. Service Manuals are available which
include detailed service information for your vehicle.
Refer to these manuals before attempting any procedure
yourself.

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 Service
Manual 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.

Start the battery save feature by doing the following:
1. Insert the key into the ignition.
2. Cycle the ignition from OFF to ACC four times with-
out going into ON. Leave the switch in the OFF position
after the fourth cycle.3. Depress the driver’s side Power Door Lock switch in
the UP direction. A single chime and a horn chirp indicate
that the process has begun.
4. Remove the key from the ignition and exit the vehicle.
5. The feature is cancelled when the ignition is cycled to
ON/RUN.
6. The vehicle will enter Battery Save Mode 45 seconds
after all doors are closed.
NOTE:The remote keyless entry and passenger exterior
door handle will not work when the Battery Save feature
is enabled. Enter the vehicle either by using the key to
open the door manually or by using the outside door
handle.
NOTE:The Vehicle Theft Alarm is disabled when the
vehicle is in Battery Save mode. Therefore, the vehicle is
not protected when the Battery Save feature is enabled.

NOTE:The exterior and interior lighting functions will
not work when the vehicle is in Battery Save Mode.
Exit Battery Save Mode by doing the following:
1. Press the driver’s door exterior handle to wake up the
vehicle.
2. If the door does not open (vehicle is armed) press the
remote keyless entry unlock button to unlock the vehicle.
3. Press the driver’s door exterior handle again to open
the door.
4. Cycle the Ignition to ON/RUN. If the ignition is NOT
cycled to ON/RUN, then the vehicle will re-enter Battery
Save Mode 45 seconds after the driver’s door is closed.Air Conditioner
Check the air conditioning system operation at the start
of the warm weather season.
NOTE:If air conditioning operation seems to be lower
than expected, check the front of the A/C condenser,
located in front of the radiator for dirt or insect accumu-
lation. Clean with a gentle water spray as required. Front
end fascia protectors may reduce air flow to the con-
denser and radiator, reducing A/C and engine cooling
performance.
