NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
AUTOSTICK
Steering Wheel Mounted Paddle Shifters Or
Console Mounted Shifter
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system can also provide you with more control
during passing, city driving, cold slippery conditions,
mountain driving, and many other situations.
1 — (–) Shift Paddle
2 — (+) Shift Paddle
362 STARTING AND OPERATING

Operation
When the shift lever is in the DRIVE (D) position, the
transmission will operate automatically, shifting between
the eight available gears. To activate AutoStick, move the
shift lever into the MANUAL (M) position (beside the
DRIVE position). The current transmission gear will be
displayed in the instrument cluster, along with a high-
lightedM(Manual) indication. When the shift lever is
in the MANUAL (M) position, tap the shift lever forward
(-) (or tap the (-) shift paddle on the steering wheel) to
downshift the transmission to the next lower gear, (or tap
the lever rearward (+) or tap the (+) shift paddle), to
command an upshift. NOTE:
Tapping one of the steering wheel-mounted shift
paddles (+/-), while the shift lever is in DRIVE, will
activate a temporary AutoStick mode. Tapping (-) to
enter AutoStick mode will downshift the transmission to
the next lower gear, while using (+) to enter AutoStick
mode will retain the current gear. The current gear will be
displayed in the instrument cluster, but the Mwill not
be highlighted. The transmission will revert back to
normal operation (if the shift lever remains in DRIVE)
after a period of time, depending on accelerator pedal
activity.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the shift lever, or the shift paddles), unless an
engine lugging or overspeed condition would result. It
will remain in the selected gear until another upshift or
downshift is chosen, except as described below.
5
STARTING AND OPERATING 363

•In temporary AutoStick mode (shift lever in DRIVE),
the transmission will automatically shift up when
maximum engine speed is reached. Lack of accelerator
pedal activity will cause the transmission to revert to
automatic operation.
• If normal AutoStick mode is engaged (shift lever in
MANUAL position), manual gear selection will be
maintained until the shift lever is returned to DRIVE,
or as described below. The transmission will not
upshift automatically at redline in this mode, nor will
downshifts be obtained if the accelerator pedal is
pressed to the floor.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear. •
The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear.
Tapping (+) (at a stop) will allow starting in second
gear. Starting out in second gear can be helpful in
snowy or icy conditions.
• If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Holding the (-) paddle depressed, or holding the shift
lever in the (-) position, will downshift the transmis-
sion to the lowest gear possible at the current speed.
• Transmission shifting will be more noticeable when
AutoStick is engaged.
364 STARTING AND OPERATING

•The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, return the shift lever to the
DRIVE position, or press and hold the (+) shift paddle (if
the shift lever is already in DRIVE) until “D” is once
again indicated in the instrument cluster. You can shift in
or out of the AutoStick mode at any time without taking
your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
DRIVE MODES
Your SRT vehicle is equipped with a SRT Drive Mode
feature. This feature gives the driver control over the
systems in the vehicle which affect its performance,
enabling the driver to tune it for desired driving sce-
narios. Below are the modes of operation:

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.

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
may cause damage to vehicle components and is not
recommended.
Automatic Transmission — If Equipped
Launch Control is only available when the following
procedure is followed:
1. Push the LAUNCH button on the center stack switch bank.
NOTE: Pushing the SRT button on the center stack or
pressing the “SRT & Apps” button on the touchscreen are
two other options to access launch control features.
Please refer to “Uconnect® Settings” within your Own-
er ’s Manual on the DVD for further information.
2. Press the “Launch RPM Set-Up” button on the touch- screen. This screen will allow you to adjust your

return to its current ESC mode.
Launch control will abort before launch completion,
display “Launch Aborted” in the cluster and return to
ESC Full ON under any the following conditions:
• The brake is applied during launch.
• The ESC system detects that the vehicle is no longer
moving in a straight line.
5
STARTING AND OPERATING 373

•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
