transmission DODGE CHALLENGER SRT 2019 Service Manual

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.
• 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.
236 STARTING AND OPERATING

•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
Your 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 scenarios.
NOTE: Refer to “SRT Drive Modes” in “Multimedia” for
further descriptions of these modes.
Launch Mode
This vehicle is equipped with a Launch Mode system that
is designed to allow the driver to consistently achieve
maximum acceleration in a straight line. Launch Mode is a
form of traction control that manages tire slip while
aggressively launching the vehicle. Launch mode is in-
tended for use during race events on a closed course where
consistent acceleration is desired. The system is not in-
tended to compensate for lack of driver experience or
familiarity with the race track. The use of this feature in
low traction (cold, wet, gravel, etc) conditions may result in
excessive wheel slip outside of the system’s control, result-
ing in an aborted launch. Launch Mode is calibrated to
provide the most benefit on an unprepared surface and will
degrade performance on prepared surfaces (such as a drag
strip).6
STARTING AND OPERATING 237

NOTE:Torque Reserve is implemented during Launch
Mode, so you may notice different engine/exhaust sounds
and increased NVH.
Preconditions:
• Launch Mode should not be used on public roads.
Always check track conditions and the surrounding
area.
• Launch mode is not available within the first 500 miles
of engine break-in.

Guidelines For Track Use
NOTE: Because of the extreme conditions encountered
during track use, any damage or wear associated with
track use may not be 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 operates
in SPORT or TRACK modes during the track event.
240 STARTING AND OPERATING

•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.
NOTE: Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
• 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 one cool down lap using minimal
braking.
• 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 endur-
ance. 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, clutch – if equipped, drive-
line and brake system. This may affect noise (NVH)
countermeasures designed into your vehicle. New com-
ponents may need to be installed to return the system to
the original NVH performance.
• For race track usage it is recommended that the axle
fluid be changed every 4 hours of on track time.
• 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.

STARTING AND OPERATING 241

•If the button is continually pushed, the set speed will
continue to decrease until the button is released, then the
new set speed will be established.
Metric Speed (km/h)
• Pushing the SET (-)button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then the
new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE: The Speed Control system maintains speed up and
down hills. A slight speed change on moderate hills is
normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.
WARNING!
Speed Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control and have an accident. Do not use Speed Control
in heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle will
deactivate the Speed Control without erasing the set speed
from memory.
Pushing the on/off button or turning the ignition switch
OFF erases the set speed from memory.
246 STARTING AND OPERATING

Adaptive Cruise Control (ACC) Operation
The Speed Control buttons (located on the right side of the
steering wheel) operates the ACC system.NOTE:
Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
20 mph (32 km/h).
The system will cancel when the vehicle speed drops below
15 mph (24 km/h).
The minimum set speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the “ready” state, the
instrument cluster display will read “ACC Ready.”

WARNING!
Drivers must be careful when backing up even when
using the Rear Park Assist system. Always check
carefully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible for
the safety of your surroundings and must continue to
pay attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
•ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear Back Up
Camera that allows you to see an on-screen image of the
rear surroundings of your vehicle whenever the gear
selector is put into REVERSE. The ParkView camera is
located on the rear of the vehicle above the rear license
plate. The image will be displayed in the touchscreen
display along with a caution note to “check entire sur-
roundings” across the top of the screen. After five seconds,
this note will disappear.
NOTE: The ParkView Rear Back Up Camera has program-
mable modes of operation that may be selected through the
Uconnect System. Refer to “Uconnect Settings” in “Multi-
media” for further information.
If your vehicle is equipped with the Camera Delay feature
and it is turned on, the rear camera image will be displayed
for up to 10 seconds when the vehicle is shifted out of
REVERSE. However, this feature is canceled if the forward
vehicle speed exceeds 8 mph (13 km/h), the transmission is
shifted into PARK, the vehicle’s ignition is cycled to OFF, or
by pressing the image defeat [X] button.
272 STARTING AND OPERATING

When the vehicle is shifted out of REVERSE (with Camera
Delay turned off), the rear camera mode is exited and the
last touchscreen appears again.
When enabled, active guide lines are overlaid on the image
to illustrate the width of the vehicle and its projected
backup path based on the steering wheel position. The
active guide lines will show separate zones that will help
indicate the distance to the rear of the vehicle.If the vehicle speed remains below 8 mph (13 km/h), the
rear view camera image will continue to be displayed until
the transmission is shifted into PARK, the vehicle’s ignition
is cycled to the OFF position, or the image defeat [X] button
is pressed.
Different colored zones indicate the distance to the rear of
the vehicle.
The following table shows the approximate distances for
each zone:
Zone
