2017 DODGE VIPER Owners Manual

NOTE:
•You must disarm the security system in order to start the
engine. Refer to “Security Alarm System” in “Things To
Know Before Starting Your Vehicle” for further informa-
tion.
• Normal starting of either a cold or a warm engine does
not require pumping or pressing the accelerator pedal.
However, if the engine has not started within three
seconds, slightly press the accelerator pedal while con-
tinuing to crank. If the engine fails to start within 15
seconds, 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. Push the red ENGINE START/STOP 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 liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter 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. Refer to “Jump-Starting” in “What To Do In
Emergencies” for further information. 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 cranking
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 second
periods of cranking with the accelerator pedal held to the
floor, the “Normal Starting” procedure should be repeated.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
MANUAL TRANSMISSION
NOTE:
The parking brake should be engaged and the gear
selector placed into 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 pressed to the
floor during each shift. As you release the clutch pedal,
lightly press the accelerator pedal.
192 STARTING AND OPERATING

CAUTION!
•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, as this will cause
abnormal wear on the clutch.
• Failure to press the clutch pedal fully to the floor
may cause increased shift efforts, and may result in
damage to the clutch and transmission.
• Do not rest your hand on the gear selector while
driving, as this may result in transmission damage.
• Do not attempt to shift the transmission if the rear
wheels are spinning due to loss of traction. Damage
to the transmission may occur.
Ensure 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 damage to the
clutch.
Shifting
Fully press the clutch pedal and lift your foot off the
accelerator pedal before shifting gears. As you release the
clutch pedal, lightly press the accelerator pedal. Damage to
the transmission or clutch may occur if you do not fully
press the clutch pedal and lift off of the accelerator pedal
when shifting.
The six-speed manual transmission has a spring that
centers the gear selector near third and fourth gear. This
spring helps you know which gear you are in when you are
shifting. Be careful when shifting from first to second or
downshifting from sixth to fifth.
Shift Pattern
5
STARTING AND OPERATING 193

The spring will try to pull the gear selector toward third
and fourth gear. Make sure you move the gear selector into
second or fifth gear. If you let the gear selector move in the
direction of the pulling, you may end shifting from first to
fourth or from sixth to third gear.
You will find it easier to use only the lower gears for most
city driving. For steady highway driving with light accel-
erations, 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
3 mph (5 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 in the ON position, and increased shift efforts into REVERSE with the ignition in the OFF position.
This is normal operation of the transmission reverse
inhibitor system.
• Shifting gears during cold weather may require an
increased effort until the transmission lubricant is warm.
This is normal and not harmful to the transmission.
• Due to the high performance nature of your drivetrain,
a certain amount of noise from the transmission is
normal. This noise can be most noticeable when the
vehicle is idling in NEUTRAL with the clutch engaged
(clutch pedal released), but it may also be heard when
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 transmis-
sion.
• You must always use first gear (or REVERSE) when
starting from a standing position.
CAUTION!
Always make sure the vehicle comes to a complete stop
before shifting into REVERSE. Failure to do so may
result in transmission damage.
194 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 in-
creased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS 1-4 4-5 5-6
mph 1745 50
(km/h) (27) (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 trans-
mission directly from first gear into fourth gear
instead of from first gear into second gear. This is
to help you get the best possible fuel economy
from your vehicle. This occurs when engine coolant is
higher than 107°F (42°C), and vehicle speed is greater than
16 mph (26 km/h) but less than 18 mph (29 km/h), and engine speed is less than 1,550 RPM, and the transmission
is in first gear, and the accelerator is at 20% throttle or less.
The “Skip Shift Indicator Light” located in the tachometer
will illuminate during these times.
When the “Skip Shift Indicator Light” illuminates, the shift
mechanism will only allow shifts from first gear to fourth
gear. After you shift the transmission into 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.
To maintain a safe speed and prolong brake life, downshift
to maintain a safe speed when descending a steep grade.
CAUTION!
If you skip more than one gear while downshifting or
downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.

STARTING AND OPERATING 195

STREET/RACE MODE — IF EQUIPPED
This vehicle is equipped with a two mode electronic
controlled damping system. This system allows for a
compliant street suspension damping setting or a firmer
race suspension damping setting. When in street mode the
system will automatically shift the suspension dampers to
the firmer Race damping setting during some hard accel-
eration and braking situations. There are two modes of
operation:
•Street Mode — This mode will give a sporty, but
comfortable ride. This mode is driver selectable when
the vehicle is placed in STREET mode (push the
“STREET” button on the Instrument Panel). This mode
is intended for a smoother ride on the various types of
pavement and road conditions while still providing
damping levels appropriate extreme capabilities.
• Race Mode — This mode is driver selectable when the
vehicle is placed in RACE mode (push the “RACE”
button on the Instrument Panel). This mode is for track
use only and will supply maximum grip to the tires. NOTE:
•
With the ignition in the ON/RUN position, the suspen-
sion damping system will be in the last mode the system
was in when the vehicle was turned off. The driver can
select either Street or Race damping mode at any time.
• The suspension mode will lock and stay in whatever the
driver selects even when the ignition is turned off and
the car restarted.
• The RACE setting will provide a much firmer ride.
• When RACE mode is enabled, a Shock symbol with
“RACE” next to it will light up in the instrument cluster.
LAUNCH MODE
This system maximizes acceleration traction for straight
line racing.
1. Bring the vehicle to a complete stop on a level track surface with the engine running.
2. Set the steering wheel for straight ahead driving.
3. Fully depress the clutch and select the first gear posi- tion.
196 STARTING AND OPERATING

4. Push and release the “LAUNCH” button (located on thesteering wheel controls).
5. Rapidly press the accelerator pedal to the floor within one second.
NOTE: If the instrument cluster message indicates all
conditions are correct for launch and the throttle is pressed
to the floor quickly (within approximately 1/2 second) the
system will hold the engine speed to a preset speed (below
the engine rev limiter speed).
6. Release the clutch aggressively. Do not ride the clutch. Release the accelerator pedal to deactivate launch control.
Pushing the launch control button or actuating the brakes
will also deactivate launch control.
NOTE:
•
Launch Mode brings the engine to optimum launch
RPM and waits for the driver to release the clutch.
Launch Mode then uses engine throttle only to achieve
controlled wheelslip for maximum acceleration through
first gear.
• Launch Mode can be used in any of the Electronic
Stability Control (ESC) Modes.
• Launch Mode should not be used within the first 500
miles (805 km) of engine break-in.
WARNING!
Launch Mode is intended for off-highway or off-road
use only and should not be used on any public
roadways. It is recommended that this feature be used
in a controlled environment, and within the limits of
the law. The capabilities of the vehicle as measured by
the performance pages must never be exploited in a

the user ’s safety or the safety of others. Only a safe,
attentive, and skillful driver can prevent accidents.
TRACK USE
Guidelines For Track Use
NOTE:Because of the extreme conditions encountered
during track use, any damage or wear associated with
track use is not covered by warranty.
• It is recommended that the shocks be operated in RACE
mode, if equipped.
• ESC is track capable in all modes.
Prior To Each Track Event/Day
• Verify all fluids are at the correct levels. Refer to “Fluid
Capacities” in “Maintaining Your Vehicle” for further
information.
• Verify the front and rear brake pads have more than ½
pad thickness remaining. If the brake pads require
changing, please burnish prior to track outing at full
pace. •
Tire pressure:
– 35psi hot recommended. This typically can be achieved with cold pressures between 25 and 29 psi,
depending on driver, track, and ambient conditions.
Conclusion Of Each Track Event
• It is recommended that a brake bleed procedure is
performed to maintain the pedal feel and stopping
capability of your brake system.
• It is recommended that each track outing should end
with a minimum of 1 cool down lap using minimal
braking.
• Following each track session, tires should be inspected
for wear.
NOTE:
• All SRT vehicles are track tested for 24 hours of endur-
ance, however, it is recommended that suspension sys-
tem, brake system, prop shaft, and ½ shaft boots should
be checked for wear or damage after every track event.
