2004 DODGE VIPER fuel

After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
TRANSMISSION SHIFTING
NOTE:The parking brake should be engaged and the
gear selector placed in REVERSE before leaving the
vehicle, especially on an incline.
Fully depress the clutch pedal before you shift gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.Be sure the transmission is in FIRST gear, (not THIRD),
when starting from a standing position. Damage to the
clutch can result from starting in THIRD.
For most city driving you will find it easier to use only
the lower gears. For steady highway driving with light
accelerations, 6th gear is recommended.
Never drive with your foot resting on the clutch pedal, or
try to hold the vehicle on a hill with the clutch pedal
partially engaged. This will cause abnormal wear on the
clutch.
Never shift into REVERSE until the vehicle has come to a
complete stop.
NOTE:During cold weather, until the transmission
lubricant has warmed, you may have difficulty shifting.
This is normal and not harmful to the transmission.
100 STARTING AND OPERATING

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 Light
There are times when you must shift directly from First to
Fourth gear instead of from First to Second. An amber
(LED) arrow on the instrument cluster will light up
during these times. This is to help you get the best
possible fuel economy.
The shift arrow will light up when engine coolant is
higher than 106ÉF (41ÉC), vehicle speed is greater than 12
MPH and less than 20 MPH, engine speed is less than
1322 RPM, you are in 1st gear and you are at 1/4 throttle
or less.
When the arrow is lit, the shift mechanism will only
allow shifts from First to Fourth gears. After you shift 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.

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on either the face of the driver's door or the
driver's side ªBº pillar. For vehicles other than passenger
cars, the cold tire inflation pressures are listed on either
the ªBº pillar, the Certification Label or in the Tire
Inflation Pressures brochure in the glove compartment.Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less that the maxi-
mum loaded vehicle condition. These pressure condi-
tions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality pre-
mium unleaded gasoline having an octane
rating of 93 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. Engine damage resulting from operating with a
heavy spark knock may not be covered by the new
vehicle warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of ªregularº gasoline be-
fore 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) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning fuel referred to as Reformulated Gasoline.
Reformulated gasolines contain oxygenates, and are spe-
cially blended to reduce vehicle emissions and improve
air quality.
The manufacturer strongly supports the use of reformu-
lated gasolines. Properly blended reformulated gasolines
will provide excellent performance and durability of
engine and fuel system components.
STARTING AND OPERATING 127

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with mate-
rials called oxygenates such as 10% alcohol, MTBE, ETBE
or TAME. Oxygenates are required in some areas of the
country during the winter months to reduce carbon
monoxide emissions. Fuels blended with these oxygen-
ates may be used in your vehicle.
CAUTION!
DO NOT use gasolines containing METHANOL.
Gasoline containing methanol may damage critical
fuel system components.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane. Gaso-
lines blended with MMT offer no performance advantage
beyond gasolines of the same octane number without
MMT. Gasolines blended with MMT reduce spark plug
life and reduce emission system performance in some
vehicles. The manufacturer recommends that gasolines
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
or not his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada because MMT can be used at higher
levels than are allowed in the United States. MMT is
prohibited in Federal and California reformulated gaso-
lines.
128 STARTING AND OPERATING

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.
STARTING AND OPERATING 129

WARNING!
Remove the fuel tank filler tube cap (gas cap) slowly
to prevent fuel spray from the filler neck that may
cause injury. The volatility of some gasolines may
cause a buildup of pressure in the fuel tank that may
increase while you drive the vehicle. This pressure
can result in a spray of gasoline and/or vapors when
you remove the cap from a hot vehicle. Removing the
cap slowly allows the pressure to vent and prevents
fuel spray. Never have any smoking materials lit in
or near the vehicle when the fuel tank filler tube cap
(gas cap) is removed or when filling the tank. Never
fill the gas tank while the engine is running.

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.
