tions are set and locked to prevent unauthorized
modification:
• Engine limited to a lowest power output state. •
Transmission locks out access to first gear and shifts
earlier than normal.
• Traction, Steering and Suspension are forced to
STREET settings.
• Steering wheel mounted paddle shifters are disabled.
• The SRT Drive Modes are not available. Pressing the
SRT button will display the unlock keypad.
• The ESC Off button is disabled.
• The Launch Control button is disabled.

STARTING AND OPERATING 369

•The vehicle will restart with VALET active if VALET
was active when the vehicle was last shut down.
• Eco (Automatic Transmission only) — Eco modifies
the vehicle’s engine and transmission settings to pro-
vide improved fuel economy at a trade-off with accel-
eration performance. Increased engine exhaust noise
and/or vibration may be noticed while Eco is active,
this is normal and will not damage the vehicle.
NOTE: Changing the Drive Mode will deactivate Eco.
Launch Mode — 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.
NOTE:
Launch mode is not available within the first 500
miles of engine break-in.
Preconditions:
• Launch control should not be used on public roads.
Always check track conditions and the surrounding
area.
• Launch Control is not available for the first 500 miles
of the vehicle’s life.
• Launch Control should only be used when the engine
and transmission are at operating temperature.
370 STARTING AND OPERATING

•Launch Control is intended to be used on dry, paved
road surfaces only. Use on slippery or loose surfaces

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.
• If your SRT vehicle is equipped with Drive Modes they
will alter the vehicle’s performance in various driving situations. It is recommended that your vehicle oper-
ates 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 Capactites” in “Main-
taining Your Vehicle” for further information.
• Prior to each track event, verify the front and rear
brake pads have more than ½ pad thickness remain-
ing. If the brake pads require changing, please burnish
prior to track outing at full pace.
• At the conclusion of each track event, it is recom-
mended 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.
374 STARTING AND OPERATING

•If equipped with a removable lower front fascia grille,
it is recommended to remove it for track use during
warm/hot weather to improve cooling airflow to
critical powertrain and cooling system components.
• All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion 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 tempera-
tures of the engine, transmission, clutch – if equipped,
driveline and brake system. This may affect noise
(NVH) countermeasures designed into your vehicle.
New components may need to be installed to return
the system to the original NVH performance.
• Tire pressure:
• 40psi hot, recommend 32psi front, 30psi rear cold NOTE:
It is recommended that you target 40psi Hot Tire
Pressure at the conclusion of each track session. Starting
at 32psi Front & 30psi Rear Cold and adjusting based on
ambient & track conditions is recommended. Tire pres-
sure can be monitored via the Driver Information Display
(DID) 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 com-
ponents 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.
2. Lap the track in this manner until you start smelling the brakes. Continue for another ½ lap at speed, then
5
STARTING AND OPERATING 375

do a two lap cool down with minimal brake applies.
Make sure the brakes are not smoking. If they are, do
another cool down lap.
3. Do not continue for more than 1 full burnishing lap after you start smelling the brakes. Do not get them
smoking heavily. This will get them too hot and affect
their life negatively in future track use.
4. Allow vehicle to sit and cool in the paddock for at least 30 min. If an infrared thermal gun is available, allow
rotors to cool to 200°F before going back out.
5. There should be a thin, ash layer when inspecting the pads installed in the caliper. Having the ash layer go
more than half the thickness of the pad material
indicates too aggressive of a burnish. 6. Sometimes, a second burnish session is required. If the
pads start smelling in the next track session, reduce
speed and braking decel to burnish targets and follow
step 2-4.
7. New pads installed on old rotors still need to be burnished. New rotors installed with old pads should
be burnished at the track or street driven for 300 city
miles to develop an adequate lining transfer layer on
the rotor surface prior to track use.
8. Rotors that pulsate during track use should be re- placed. Resurfacing of the rotors is not recommended,
as it removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, mak-
ing it less robust and increasing the likelihood of
pulsation in further track use.
376 STARTING AND OPERATING

DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
•Slow down during rainstorms or when the roads are
slushy.
• Slow down if the road has standing water or puddles.
• Replace tires when tread wear indicators first become
visible.
• Keep tires properly inflated.
• Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a
sudden stop.
5
STARTING AND OPERATING 377

Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not eliminate,
the amount of wheel slip across a given axle for im-
proved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
CAUTION!
•Due to lower ground clearance, driving your ve-
hicle up steep driveways, approach ramps or near
parking blocks may cause damage to the front
fascia and ground effects.
• Driving through snow more than 4 inches (100 mm)
deep may cause damage to the front fascia and
ground effects.
Flowing/Rising Water
WARNING!
Do not drive on, or cross, a road or a path where
water is flowing and/or rising (as in storm run-off).
Flowing water can wear away the road or path’s
surface and cause your vehicle to sink into deeper
water. Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cautions
and Warnings before doing so.
