LAUNCH CONTROL — IF EQUIPPED
This vehicle is equipped with a Launch Control system that is designed
to allow the driver to achieve maximum vehicle acceleration in a
straight line. Launch Control is a form of traction control that manages
tire slip while launching the vehicle. This feature is intended for use
during race events on a closed course where consistent quarter mile
and zero to sixty times are desired. The system is not intended to
compensate for lack of driver experience or familiarity with the race
track. Use of this feature in low traction (cold, wet, gravel, etc.)
conditions may results in excess wheel slip outside this systems control
resulting in an aborted launch.
Preconditions:
• Launch Control should not be used on public roads. Always checktrack conditions and the surrounding area.
• Launch Control is not available within the first 500 miles (805 km) of engine break-in.
• Launch Control should only be used when the engine and transmis- sion are at operating temperature.
•
Launch Control is intended to be used on dry, paved road surfaces only.
CAUTION!
Use on slippery or loose surfaces may cause damage to vehicle
components and is not recommended. Launch Control is only available when the following procedure is
followed:
NOTE:
Pushing the SRT button on the Select-Track switch or pressing
the “Apps” button on the touchscreen are the two options to access
launch control features. Please refer to “SRT Drive Modes” in “Multi-
media” for further information.
1. Press the “Race Options” button on the touchscreen or push the LAUNCH button on the Select-Track switch.
2. Press the “Launch RPM Set-Up” button on the touchscreen. This screen will allow you to adjust your launch RPM’s for optimum
launch/traction.
3. Press the “Activate Launch Control” button on the touchscreen, follow instructions in the instrument cluster display.
• Make sure the vehicle is not moving.
• Put vehicle in first gear.
• Steering wheel must be pointing straight.
• Vehicle must be on level ground.
• Apply Brake Pressure.
• While holding the brake, rapidly apply the accelerator pedal to wide open throttle. The engine speed will hold at the RPM that
was set in the “Launch RPM Set-up” screen.

Guidelines For Track Use
CAUTION!
Because of the extreme conditions encountered during track use,
any damage or wear associated with track use is not covered by
warranty.
• If your SRT vehicle is equipped with Drive Modes they will alter the vehicle’s performance in various driving situations. It is recom-
mended that your vehicle operates in SPORT or TRACK modes
during the track event.
• Prior to each track event/day, verify all fluids are at the correct levels. Refer to “Fluid Capacities” in “Technical Specifications” for
further information.
• Prior to each track event, 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.
• At the 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 Brembo High Performance brake system.
• It is recommended that each track outing should end with a minimum of 1 cool down lap using minimal braking. • All SRT vehicles are track tested for 24 hours of endurance,
however, it is recommended that suspension system, brake system,
prop shaft, and ½ shaft boots should be checked for wear or damage
after every track event.
• Track usage results in increased operating temperatures of the engine, transmission, driveline and brake system. This may affect
Noise Vibration Harshness (NVH) countermeasures designed into
your vehicle. New components may need to be installed to return the
system to the original NVH performance.
• Tire pressure: – Below 42 psi (289 kpa) hot and 33 psi (227 kpa) cold recom-
mended.
NOTE: It is recommended that you target below 42 psi (289 kpa) Hot
Tire Pressure at the conclusion of each track session. Starting at 33 psi
(227 kpa) Cold and adjusting based on ambient & track conditions is
recommended. Tire pressure can be monitored via the instrument
cluster display and can assist with adjustments.
Track burnishing your brakes:
To avoid “green lining fade” during track use, the brake pads and rotors
must have a thermal burnish for factory installed components or when
new brake friction components are installed:
1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately 0.60 - 0.80g max without ABS intervention.
