instrument cluster DODGE CHALLENGER SRT 2019 Service Manual

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.
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.
Automatic Transmission Gear Selector
230 STARTING AND OPERATING

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:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at an authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
234 STARTING AND OPERATING

3. Push and hold the ignition switch until the engine turnsOFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your earliest
possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
AutoStick
AutoStick is a driver-interactive transmission feature pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove 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. 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-
lighted
M(Manual) indication. When the gear selector is

STARTING AND OPERATING 235

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.
• Launch Mode should only be used when the engine and
transmission are at operating temperature.
• Launch Mode 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 recom-
mended.
Automatic Transmission — If Equipped
Launch Mode is only available when the following proce-
dure is followed:
1. Push the LAUNCH button on the center stack switch bank. NOTE:
Pushing the SRT button on the center stack or

inform the driver if one or more of the above conditions
have not been met.
238 STARTING AND OPERATING

7. While holding the clutch depressed, rapidly apply andhold the accelerator pedal to wide open throttle. The
engine speed will hold at the pre-selected launch RPM.
The engine speed will hold at the RPM that was set in
the “Launch RPM Set-up” screen.
NOTE: Messages will appear in the instrument cluster to
inform the driver if one or more of the above conditions
have not been met.
8. When conditions 4 through 7 have been met, the instru- ment cluster display will read “Launch Ready Release
Clutch”. Release the clutch quickly and continue to hold
the throttle to execute launch. Refer to “Manual Trans-
mission – If Equipped” in this section for further infor-
mation.
Release the clutch and continue to hold wide open throttle
to launch.
9. Keep the vehicle pointed straight.
Launch mode will be active until the vehicle reaches
62 mph (100 km/h), at which point the ESC system will
return to its current ESC mode.
Launch mode 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.
• The “ESC OFF” button is pushed to change the ESC
system to another mode.
NOTE: After launch mode has been aborted, ESC will
return to its current ESC mode.
CAUTION!
Do not attempt to shift when the drive wheels are
spinning and do not have traction. Damage to the
transmission may occur.
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

ELECTRIC POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to “Drive Modes” in
this section for further information.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.If the Steering icon is displayed and the “SER-
VICE POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE SYSTEM”
message is displayed within the instrument clus-
ter, this indicates the vehicle needs to be taken to the dealer
for service. Refer to “Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” for further informa-
tion.
NOTE:
• Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
