2017 DODGE VIPER suspension

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.

WARNING!(Continued)
reckless or dangerous manner, which can jeopardize
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.
198 STARTING AND OPERATING

It is recommended you contact your authorized tire dealer
or original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have a collision
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
• Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.
(Continued)
WARNING! (Continued)
•Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS (TRACTION DEVICES)
Due to limited clearance, tire chains or traction devices are
not recommended.
CAUTION!
Damage to the vehicle may result if tire chains are
used.
