2018 DODGE CHALLENGER SRT engine

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.
3. Push and hold the ignition switch until the engine turns OFF.
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.

STARTING AND OPERATING 227

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
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, en-
abling the driver to tune it for desired driving scenarios.
6
STARTING AND OPERATING 229

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 achieve maximum
vehicle acceleration in a straight line. Launch Mode 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 result in
excess wheel slip outside of this system’s control, resulting
in an aborted launch.
NOTE:
• Launch mode is not available within the first 500 miles
of engine break-in.
• 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.

232 STARTING AND OPERATING

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.
• 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)
6
STARTING AND OPERATING 233

8. Rotors that pulsate during track use should be replaced.Resurfacing of the rotors is not recommended, as it
removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, making
it less robust and increasing the likelihood of pulsation
in further track use.
FUEL SAVER TECHNOLOGY 6.4L ONLY — IF
EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine’s eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
HYDRAULIC POWER STEERING — IF EQUIPPED
The hydraulic power steering system is sport tuned and
will give you good vehicle response and increased ease of
maneuverability in tight spaces. The system will provide
mechanical steering capability if power assist is lost. If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•
Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This
is due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in
any way damage the steering system.
WARNING!
Continued operation with reduced power steering as-
sist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
