catalytic converter DODGE VIPER 2004 ZB / 2.G Owners Manual

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.
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 (BeltAlertŸ) in
the Occupant Restraints section for deactivating the
system.

WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from a booster battery or the battery in
another vehicle. This type of start can be dangerous
if done improperly, so follow this procedure care-
fully. See section 6 of this manual for jump starting
instructions.
If the engine fails to start after you have followed the
ªNORMAL STARTINGº procedure, it may be flooded.
Push the accelerator pedal all the way to the floor and
hold it there while cranking the engine. This should clear
any excess fuel in case the engine is flooded.NOTE:To prevent damage to the starter, do not crank
the engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the start
button is released. If this occurs, continue cranking with
the accelerator pedal pushed all the way to the floor.
Release the accelerator pedal and the start button once
the engine is running smoothly.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the ªNORMAL STARTINGº procedure
should be repeated.

Sulfur In Gasoline
Your vehicle may have been designed to meet California
low emission standards on clean burning, low sulfur,
California gasoline. Gasoline sold outside of California is
allowed to have higher sulfur levels that may affect the
performance of your vehicle's catalytic converter. This
may cause the Malfunction Indicator Light or Service
Engine Soon Light to illuminate.
The illumination of this light while operating on high
sulfur gasoline does not necessarily mean your emission
system control system is malfunctioning. The manufac-
turer recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if the
problem is fuel related before returning your vehicle to
an authorized dealer for service.
NOTE:If the Malfunction Indicator light or Service
Engine Soon light is flashing, immediate service is re-
quired.
Materials Added to Fuel
All gasoline sold in the United States and Canada is
required to contain effective detergent additives. The use
of additional detergents or other additives is not needed
under normal conditions.
ADDING FUEL
The fuel tank filler tube has a restricting door about 2
inches (50mm) inside the opening. If using a portable
container, it should have a flexible nozzle long enough to
force open the restricting door.

JUMP-STARTING PROCEDURES
WARNING!
²Do not attempt to push or tow your vehicle to get
it started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite
and damage the converter and vehicle. If the
vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly, so
follow this procedure carefully.
²Take care to avoid the radiator cooling fan and
accessory drive whenever the hood is raised. You
can be hurt by the moving components.
WARNING!
²Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don't lean over battery when attaching
clamps or allow the clamps to touch each other. If
acid splashes in eyes or on skin, flush contami-
nated area immediately with large quantities of
water.
²A battery generates hydrogen gas that is flam-
mable and explosive. Keep flame or spark away
from the top of the battery. Do not use a booster
battery or any other booster source with an output
that exceeds 12 volts.

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.

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturers specifica-
tions, should be obtained immediately.To minimize the possibility of catalytic converter dam-
age:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do 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
