Transporting Pets
Deploying airbags could harm your pet. An unrestrained
pet will be thrown about and possibly injured, or injure a
passenger during panic braking or in a collision.
Pets should be restrained in pet harnesses or pet carriers
that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
The engine in your new Viper does not require a long
break-in period. Following these few simple guidelines is
all that is necessary for a good break-in:
For the first 500 miles (800 km):
•Keep your vehicle speed below the legal, posted speed
limit and your engine speed below 4,000 rpm.
•Avoid driving at a constant speed, either fast or slow,
for long periods of time.
•Do not make any full throttle starts and avoid full
throttle acceleration.
•Use the proper gear for your speed range.
•Wait until the engine has reached normal operating
temperature before driving at the recommended maxi-
mum break-in speed.
•Avoid excessive idling.
•Check the engine oil level at every fuel fill.
NOTE:A new engine will consume some oil during the
first few thousand miles of operation. This should be
considered as a normal part of the break-in and not
interpreted as a sign of difficulty.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Page 54 of 264
Safety Checks You Should Make Outside the
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or side wall
cracks. Check wheel nuts for tightness and tires for
proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if gasoline fumes are
present, the cause should be corrected immediately.

Trunk/Liftgate Ajar Light
This light indicates that the trunk/liftgate is not
latched.
Engine Coolant Temperature Light
A red LED light on the Coolant Temperature
gauge will illuminate to warn of an overheated
engine coolant condition.
Low Oil Pressure Light
A red LED light on the Oil Pressure gauge will
illuminate to indicate low engine oil pressure. The
light should come on briefly as a bulb check when the
engine is first started. If the light stays on or comes on
while driving, stop the vehicle and shut off the engine.
DO NOT operate the vehicle until the cause is corrected.
NOTE:This light does not indicate how much oil is in
the engine. The engine oil level must be checked using
the procedure shown in section 7. (See page 172 for more
information.)
Charge System Light
A red LED light on the Voltage gauge will illumi-
nate when there is a charging system malfunction
or a possible accessory drive belt failure.
CAUTION!
The accessory belt also drives the water pump.
Operating the vehicle with a failed belt can cause
engine overheating and possible severe engine dam-
age.
Fog Light ON Indicators
This light indicates that the front fog lights are on.
(See page 79 for more information.)
This light indicates that the rear fog lights are on.

This gauge does not indicate the amount of oil in the
engine. The engine oil level must be checked under the
hood. Check the level often during severe usage.
Fuel Gauge
This gauge shows the amount of fuel in the gas
tank. The reaction time of the gauge has been
slowed to avoid needle fluctuation during pe-
riods of high G force cornering.
Voltage Gauge
This gauge shows the electrical system voltage.
The normal operating voltage is from 12 to 14
volts with the engine running. If the pointer
remains at either the high or low ends of the
scale, the electrical system should be serviced.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
Press and release the Time button to display the time.
Press and release the button a second time to turn off the
time display.
Clock Setting Procedure
1. Turn the ignition switch to the “ON” or “ACC”
position. Using the point of a ballpoint pen or similar
object, press either the “H” (Hour) or “M” (Minute)
buttons on the radio. The display will show the time.

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.
172 MAINTAINING YOUR VEHICLE
Page 173 of 264

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.
•Day or night temperatures are below 32°F (0°C)
•Stop and go driving
•Extensive engine idling
•Driving in dusty conditions
•Short trip driving of less than 10 miles (16.2 km)
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C)
•Taxi, Police, or delivery service (commercial service)Engine Oil Dipstick

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.
