engine DODGE VIPER 2008 ZB II / 2.G Owner's Manual

If the engine is 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 up to 15
seconds 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.
After Starting
The idle speed will automatically decrease as the engine
warms up.
TRANSMISSION SHIFTING
NOTE:The parking brake should be engaged and the
gear selector placed in REVERSE before leaving the
vehicle, especially when parked on an incline.
Your vehicle is equipped with a high torque capacity dual
disc clutch. The clutch pedal must be fully depressed to
the floor during each shift. As you release the clutch
pedal, lightly depress the accelerator pedal.
CAUTION!
Failure to depress the clutch pedal fully to the floor
may cause increased shift efforts, and may result in
damage to the clutch and transmission.

driving. The noise may also be more noticeable when
the transmission is warm. This noise is normal and is
not an indication of a problem with your clutch or
transmission.
Recommended Shift Speeds
To use your manual transmission for fuel economy it
should be upshifted as listed below. Shift at the vehicle
speeds listed for acceleration. Earlier upshifts during
cruise conditions (relatively steady speeds) will result in
increased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS
1-2 2-3 3-4 4-5 5-6
MPH 15 25 40 45 50
(km/h) (24) (40) (64) (72) (80)
Higher upshift speeds may be used to obtain a desired
acceleration rate.
Skip Shift Indicator Light
There are times when you must shift the transmis-
sion directly from First gear to Fourth gear instead
of from First gear to Second gear. This is to help you get
the best possible fuel economy from your vehicle. This
occurs when engine coolant is higher than 106ÉF (41ÉC),
and vehicle speed is greater than 12 MPH but less than 20
MPH, and engine speed is less than 1322 RPM, and the
transmission is in 1st gear, and the accelerator is at 1/4
throttle or less. The Skip Shift Indicator Light located in
the tachometer will turn Amber during these times.
When the indicator light turns amber, the shift mecha-
nism will only allow shifts from First gear to Fourth gear.
After you shift the transmission to Fourth gear, you can
press the clutch in and shift to another forward gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.
138 STARTING AND OPERATING

To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have an accident.
CAUTION!
If you skip more than one gear while downshifting
or downshift at too high an engine speed, you could
damage the engine, transmission, or clutch.
DRIVING ON SLIPPERY SURFACES
Acceleration
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
You could lose control of the vehicle and possibly
have an accident. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).

Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
CAUTION!
Driving your vehicle through deep puddles at speeds
over 5 mph, may cause water to be ingested into the
engine. This can cause severe engine damage.3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain enough distance between your vehicle and
the vehicle in front to avoid a collision in a sudden stop.
DRIVING THROUGH WATER
Driving through water more than a few inches/
millimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
140 STARTING AND OPERATING

Flowing/Rising Water
WARNING!
Do not drive on or cross a road or a path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path's surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following before
doing so:
CAUTION!
²Always check the depth of the standing water before
driving through it. Never drive through standing water that
is deeper than the bottom of the tire rims mounted on the
vehicle.
²Determine the condition of the road or the path that is
under water and if there are any obstacles in the way before
driving through the standing water.
²Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
²Driving through standing water may cause damage to your
vehicle's drivetrain components. Always inspect your ve-
hicle's fluids (i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water. Do not
continue to operate the vehicle if any fluid appears con-
taminated, as this may result in further damage. Such
damage is not covered by the new vehicle limited warranty.
²Getting water inside your vehicle's engine can cause it to
lockup and stall out and cause serious internal damage to
the engine. Such damage is not covered by the new vehicle
limited warranty.

WARNING!
²Driving through standing water limits your vehi-
cle's traction capabilities. Do not exceed 5 mph (8
km/h) when driving through standing water.
²Driving through standing water limits your vehi-
cle's braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
²Getting water inside your vehicle's engine can
cause it to lockup and stall out and leave you
stranded.
²Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
PARKING BRAKE
The parking brake should always be applied when the
driver is not in the vehicle.
WARNING!
Before leaving the vehicle, make sure you fully apply
the parking brake and shift the transmission into
REVERSE. Failure to do so may cause the vehicle to
roll and cause damage or injury.
As an added precaution when parking the vehicle, turn
the front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade.
To apply the parking brake, grasp the handle and pull it
rearward until you feel resistance. To release the parking
brake, grasp the handle and pull it slightly while pressing
the button on the end of the handle. When the button

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will
be some loss of overall braking effectiveness. You may
notice increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake System Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Brake Pad Break-In
NOTE:Your vehicle is equipped with a high perfor-
mance braking system. The brake pads are a semi-
metallic compound, which offer superior fade resistance
for consistent operation. A compromise to using this type
of brake pad is that the brakes may squeal slightly under
certain weather and operating conditions (.i.e., during
light brake applications).
The brakes on your new vehicle do not require a long
break-in period. However, you should avoid repeated
hard brake applications from high speeds during initial
break-in. In addition, you should avoid severe brake
loading, such as may be encountered when descending
long mountain grades.

FUEL REQUIREMENTS
8.4L Engine
The 8.4L engine is designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality premium unleaded
gasoline with an octane rating of 91 or
higher.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of ªpremiumº gasoline
before considering service for the vehicle.Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as ªReformulated Gasolineº.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
168 STARTING AND OPERATING

Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and they would result in additional
cost. Therefore, you should not have to add anything to
the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives, which are now being sold as
octane enhancers, is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives are not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
170 STARTING AND OPERATING

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Keep the trunk closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located behind the fuel filler door above
the rear tire on the passenger side of the vehicle. To access
the gas cap, grasp the finger pull (on the left side of the
fuel filler door) and pull it open. The door will pivot
toward the front of the vehicle.
