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
146 MAINTAINING YOUR VEHICLE
Page 147 of 236

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 Mopartparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Mopartparts 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.

NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain the maintenance service
recommendations by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle's engine, the
engine oil must be maintained, at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
148 MAINTAINING YOUR VEHICLE
Page 149 of 236

The best time to check the oil level is approximately 5
minutes after a fully warmed up engine is turned off or
before starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground also
will improve the accuracy of the oil level readings. Add
oil only when the level is below the SAFE mark.Changing Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed.
IfANYof the following apply to you, then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow the maintenance rec-
ommendations in ScheduleB.
²Day or night temperatures are below 32ÉF (0ÉC)
²Stop and go driving
²Extensive engine idling
²Driving in dusty conditions
²Short trip driving of less than 10 miles (16.2 km)
²More than 50% of your driving is at sustained high
speeds during hot weather, above 90ÉF (32ÉC)
²Taxi, Police, or delivery service (commercial service)

present a problem to the environment. Contact your
dealer, service station, or governmental agency for advice
on how and where used oil can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
All manufacturer's engines have a full-flow type dispos-
able oil filter. Use a filter of this type for replacement. The
quality of replacement filters varies considerably. Only
high quality filters should be used to assure most efficient
service. Mopartengine oil filters are high quality oil
filters and are recommended.
Drive Belts Ð Check Condition and Tension
At the mileage shown in the appropriate ªMaintenance
Scheduleº, check the condition of the drive belt for
condition and proper tension. Improper belt tension can
cause belt slippage and failure.
Inspect the drive belt for evidence of cuts, cracks, or
glazing and replace it if there is any sign of damage
which could result in belt failure.
Spark Plugs
Spark plugs must fire properly to assure proper engine
performance and emission control. Install new recom-
mended plugs with the recommended gap at the speci-
fied mileage.
Refer to the ªVehicle Emission Control Informationº label
in the engine compartment for spark plug information.

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.
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.
Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on ªMaintenance Schedule Aº. If,
however, you drive the vehicle frequently under dusty or
severe conditions, the filter element should be inspected
periodically and replaced if necessary at the intervals
shown in ªMaintenance Schedule Bº.
WARNING!
The air cleaner can provide protection if the engine
backfires. Do not remove the air cleaner unless such
removal is necessary for repair or maintenance.
Make sure that no one is near the engine compart-
ment before starting the vehicle with the air cleaner
removed. Failure to do so can result in serious
personal injury.

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. Frontend fascia protectors may reduce air flow to the con-
denser and radiator, reducing A/C and engine cooling
performance.
WARNING!
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal injury
or damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced repairman.
Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere. The manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recycling and recovery equipment that meets
SAE standard J1991.
