CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
•Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Ignition Park Interlock
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF mode. NOTE:
The transmission is NOT locked in PARK when the
ignition is in the ACC mode (even though the engine will
be off). Ensure that the transmission is in PARK, and the
ignition is OFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed. The brake pedal must
also be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.
Eight-Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
on the gear selector and in the instrument cluster.
To select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To
shift the transmission out of PARK, the engine must be
running and the brake pedal must be pressed. You must
also press the brake pedal to shift from NEUTRAL into

STARTING AND OPERATING 221

DRIVE or REVERSE when the vehicle is stopped or mov-
ing at low speeds. Select the DRIVE range for normal
driving.
NOTE:In the event of a mismatch between the gear
selector position and the actual transmission gear (for
example, driver selects PARK while driving), the position
indicator will blink continuously until the selector is re-
turned to the proper position, or the requested shift can be
completed. The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector provides PARK, REVERSE,
NEUTRAL, DRIVE, and MANUAL (AutoStick) shift posi-
tions. Manual shifts can be made using the AutoStick shift
control. Toggling the gear selector forward (-) or rearward
(+) while in the MANUAL (AutoStick) position (beside the
DRIVE position) will manually select the transmission
gear, and will display the current gear in the instrument
cluster as M1, M2, M3, etc. Refer to
AutoStickin this
section for further information.
Automatic Transmission Gear Selector
222 STARTING AND OPERATING

NOTE:If the gear selector cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed forward)
it is probably in the MANUAL (AutoStick, +/-) position
(beside the DRIVE position). In MANUAL (AutoStick)
mode, the transmission gear is displayed in the instrument
cluster (as M1, M2, M3, etc.). Move the gear selector to the
right (into the DRIVE [D] position) for access to PARK,
REVERSE, and NEUTRAL.
Gear Ranges
Do not depress the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE: After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake. When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
When exiting the vehicle, always:
•
Apply the parking brake.
• Shift the transmission into PARK.
• Turn the ignition OFF.
• Remove the key fob from the vehicle.
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.

brake pedal. Otherwise, damage to the gear selector
could result.
• DO NOT race the engine when shifting from PARK
or NEUTRAL into another gear range, as this can
damage the drivetrain.
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:
• When shifting into PARK, push the lock button on the
gear selector and firmly move the selector all the way
forward until it stops and is fully seated.
• Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
• With the brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop. NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.

STARTING AND OPERATING 225

DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, or traveling into strong head winds), use the
AutoStick shift control (refer to “AutoStick” in this section
for further information) to select a lower gear. Under these
conditions, using a lower gear will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE posi-
tion) enables full manual control of transmission shifting(also known as AutoStick mode; refer to “AutoStick” in this
section for further information). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the transmission
gear, and will display the current gear in the instrument
cluster as M1, M2, M3, etc.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
226 STARTING AND OPERATING

Operation
When the gear selector is in the DRIVE (D) position, the
transmission will operate automatically, shifting between
the eight available gears. To activate AutoStick, move the
gear selector 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 gear selector is
in the MANUAL (M) position, tap the gear selector for-
ward (-) (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 gear selector 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 gear selector remains in DRIVE)
after a period of time, depending on accelerator pedal
activity.
• The shift paddles may be disabled (or re-enabled, as
desired) using the SRT Drive Modes.
In AutoStick mode, the transmission will shift up or down
when (+/-) is manually selected by the driver (using the
gear selector, or the shift paddles), unless an engine lug-
ging or overspeed condition would result. It will remain in
the selected gear until another upshift or downshift is
chosen, except as described below.
• In temporary AutoStick mode (gear selector in DRIVE),
the transmission will automatically shift up when maxi-
mum engine speed is reached. Lack of accelerator pedal
activity will cause the transmission to revert to auto-
matic operation.
• If normal AutoStick mode is engaged (gear selector in
MANUAL position), manual gear selection will be main-
tained until the gear selector is returned to DRIVE, or as
described below. The transmission will not upshift au-
tomatically at redline in this mode, nor will downshifts
be obtained if the accelerator pedal is pressed to the
floor.
228 STARTING AND OPERATING

•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.
NOTE: Except in Demon vehicles when in DragTrans-
mission mode. In Dragtransmission mode the vehicle can
only be launched in 1st gear.
• 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 gear
selector 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.
• The system may revert to automatic shift mode if a fault
or overheat condition is detected.
To disengage AutoStick mode, return the gear selector to
the DRIVE position, or press and hold the (+) shift paddle
(if the gear selector 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

countermeasures designed into your vehicle. New com-
ponents may need to be installed to return the system to
the original NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommended 32psi (221kpa) front,
30psi (207 kpa) rear cold
NOTE: It is recommended that you target 40psi (276kpa)
Hot Tire Pressure at the conclusion of each track session.
Starting at 32psi (221kpa) Front and 30psi (207 kpa) Rear
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 compo-
nents are installed:
1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately 0.60-0.80g max with-
out ABS intervention.
2. Lap the track in this manner until you start smelling the brakes. Continue for another half lap at speed, then 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 one 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 (93.3°C) 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 indi-
cates 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
steps two through four.
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.
