DODGE VIPER 2009 ZB II / 2.G Owners Manual

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 of this manual
for proper coolant selection.
Winter Operation
•
Use the Defrost mode to direct cold air away from the
occupants during engine warm-up in cold weather.
•The blower air will heat faster in cold weather if you
use only the low blower speeds for the first ten
minutes of vehicle operation.
•Use of the air Recirculation mode during winter
months is not recommended because it may cause
window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will insure ad-
equate system lubrication to minimize the possibility of
compressor damage when the system is started again.

Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
Outside Air Intake
When operating the system, particularly during the win-
ter months, make sure the air intake, at the right side of
the hood, is free of ice, slush, snow, or other obstructions
such as leaves. Leaves collected in the air-intake plenum
may reduce airflow and plug the plenum water drains.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct any other occupant to buckle their seat
belt.
WARNING!
•Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
injured seriously or fatally. Don’t leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
(Continued)
WARNING! (Continued)
•Be sure to turn off the engine if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the gear selection lever or
by pressing the accelerator pedal. This may cause
excessive heat in the exhaust system, resulting in
overheating and vehicle fire, which may cause
serious or fatal injuries.
CAUTION!
Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures, which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
134 STARTING AND OPERATING

Normal Starting
CAUTION!
The engine in your vehicle is designed for operation
down to 0°F (-18°C). Starting the engine below 0°F
(-18°C) creates a potential for scuffing or seizing of
internal components in this very high performance
engine. To prevent engine damage, do not start the
engine at temperatures below 0°F (-18°C).
NOTE:
•You must disarm the security system in order to start
the engine. For details, refer to “Security Alarm Sys-
tem” in Section 2 of this manual
•Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator
pedal. However, if the engine has not started within
three seconds, slightly depress the accelerator pedalwhile continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the OFF/LOCK
position, wait five seconds, then repeat the normal
starting procedure.
To start the engine:
1. Fully apply the parking brake.
2. Press the clutch pedal to the floor.
NOTE:The engine will not start unless the clutch pedal
is pressed to the floor.
3. Place the gear selector in NEUTRAL
4. Insert the ignition key fully into the ignition switch
5. Turn the key to the ON/RUN position.

6. Press the red ENGINE START button located on the
instrument panel. Release the button when the engine
starts.If Engine Fails to Start
CAUTION!
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.
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.

136 STARTING AND OPERATING

WARNING! (Continued)
•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 carefully. See section 6 of
this manual for jump starting instructions.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the ENGINE
START button is released. If this occurs, continue crank-
ing up to 15 seconds with the accelerator pedal pushed
all the way to the floor. Release the accelerator pedal and
the ENGINE START button once the engine is running
smoothly.If the engine shows no sign of starting after two 15 sec-
ond periods of cranking with the accelerator pedal held
to the floor, the NORMAL STARTING procedure should
be repeated.
After Starting
The idle speed will automatically decrease as the engine
warms up.
MANUAL TRANSMISSION
NOTE:The parking brake should be engaged and the
shift lever 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.
STARTING AND OPERATING 137

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.
Be sure the transmission is in FIRST gear when moving
forward from a standing position.
CAUTION!
Failure to start out in FIRST gear when moving
forward from a starting position may result in dam-
age to the clutch.
You will find it easier to use only the lower gears for most
city driving. For steady highway driving with light
accelerations, SIXTH 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:
•Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
5 mph (8 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete
stop, you may notice light shift efforts into REVERSE
with the ignition key ON, and increased shift efforts
into REVERSE with the ignition key OFF. This is
normal operation of the transmission reverse inhibitor
system.
