WARNING!
If both ABS and/or Brake Warning lamps become
illuminated, please seek service immediately! Your
Viper will have diminished braking capability and
control if ABS and/or service brake systems are not
working properly. Have your brake system serviced
immediately.
Skip Shift Indicator
This indicator is located in the Tachometer. There
are two LED lights. The amber LED light will come
on when you are being prevented from shifting from First
to Second or Third gear. The tachometer’s shift arrow also
houses a red LED light that activates when the tachom-
eter gauge pointer goes above 5600 RPM and it shuts off
when the tachometer pointer falls below 5500 RPM. The
indicator serves as a visual aid to shift before reaching the
red line.
Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD II which provides in-field
emissions inspection tests required in some
states. If certain self-diagnostic monitors are
not complete, the light starts flashing 14 seconds after the
key is switched on and will continue to flash for approxi-
mately 11 seconds. If the OBD II monitors have com-
pleted, the malfunction indicator lamp will not flash as
described above.
The light will illuminate when the key is turned to the
ON position before engine start. The light will remain on
steady until the engine has started. If the bulb does not
come on when turning the key from OFF to ON have the
condition checked promptly. The light will turn off after
the engine has started, unless a malfunction is present.

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. (See page 169 for more information.)
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.

CD Diagnostic Indicators
When driving over a very rough road, the CD player may
skip momentarily. Skipping will not damage the disc or
the player, and play will resume automatically.
As a safeguard and to protect your CD player, one of the
following warning symbols may appear on your display.
A CD HOT symbol indicates the player is too hot.
CD HOT will pause the operation. Play can be resumed
when the operating temperature is corrected or another
MODE is selected.CD ERROR will appear on the display if the laser is
unable to read the Disc data for the following reasons:
•Warped disc
•Excessive vibration
•Disc inserted upside down
•Damaged disc
•Water condensation on optics
SATELLITE RADIO — IF EQUIPPED
Satellite radio uses direct satellite to receiver broadcast-
ing technology to provide clear digital sound, coast to
coast. The subscription service provider is Sirius™ Satel-
lite Radio. This service offers up to 100 channels of music,
sports, news, entertainment, and programming for chil-
dren, directly from its satellites and broadcasting studios.
106 UNDERSTANDING YOUR INSTRUMENT PANEL
These indicators are molded into the bottom of the tread
grooves and will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the indicators appear
in 2 or more adjacent grooves, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident result-
ing in serious injury or death.
Keep unmounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
STARTING AND OPERATING 143

wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. You could lose control
and have an accident resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
144 STARTING AND OPERATING
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
Low Tire Pressure (LTP) System
Low Tire Indicator
The Low Tire indicator in the Liquid Crystal Display
(LCD) of the instrument cluster will flash slowly and a
single chime will sound to warn if tire pressure falls
below 20 psi (138 kpa). The indicator will flash more
rapidly and a continuous tone will sound to warn if tire
pressure falls below 14 psi (97 kpa). Seek repair as soon as
possible.
If the indicator stays on and one chime will sound, a
system failure has occurred. See your dealer for service.
STARTING AND OPERATING 145

Although the tires are designed with a “run flat” feature
that allows the vehicle to be driven about 50 miles (80
km) at 55 m.p.h. (88 kph), immediate service should be
obtained if the Low Tire indicator is activated.
WARNING!
Do not exceed 55 m.p.h. (88 k.p.h.) if the LOW Tire
indicator in the instrument cluster is illuminated.
Vehicle handling and braking may be reduced. You
could have an accident and be severely or fatally
injured.
NOTE:The “run flat” feature eliminates the need for a
spare tire and jack. This vehicle is not equipped with
either a spare tire or jack.
CAUTION!
The Low Tire Pressure (LTP) system has been opti-
mized for the original equipment tires and wheels.
The LTP system pressures have been established for
the tire size equipped on your vehicle. Undesirable
operation or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. After-market wheels can cause
sensor damage. Do not use tire sealant or balance
beads if your vehicle is equipped with the LTP
system as damage to the sensors may result.
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.
