2021 DODGE CHALLENGER traction control

98STARTING AND OPERATING
If ACC is set when the vehicle speed is below
20 mph (32 km/h), the set speed will default to
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below
20 mph (32 km/h).
If either system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be
the current speed of the vehicle.
NOTE:
Keeping your foot on the accelerator pedal can
cause the vehicle to continue to accelerate
beyond the set speed. If this occurs, the
message “DRIVER OVERRIDE” will display in the
instrument cluster display.

If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
be controlling the distance between your
vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of
the accelerator pedal.

To Cancel
The following conditions cancel the ACC or Fixed
Speed Cruise Control systems:
The brake pedal is applied.
The parking brake is applied.
The CANC (cancel) button is pushed.
An Anti-Lock Brake System (ABS) event occurs.
The gear selector is removed from the DRIVE
position.
The Electronic Stability Control/Traction Control
System (ESC/TCS) activates.
The following conditions will only cancel the ACC
system:

The vehicle speed goes below 15 mph (24 km/h).

To Turn Off
The system will turn off and erase the set speed in
memory if:
The Adaptive Cruise Control (ACC) on/off button
is pushed
The Fixed Speed Cruise Control on/off button is
pushed
The ignition is placed in the OFF position
To Resume
If there is a set speed in memory, push the RES
(resume) button and remove your foot from the
accelerator pedal. The instrument cluster display
will show the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
WARNING!
In Fixed Speed Cruise Control mode, the system
will not react to vehicles ahead. In addition, the
proximity warning does not activate and no
alarm will sound even if you are too close to the
vehicle ahead since neither the presence of the
vehicle ahead nor the vehicle-to-vehicle distance
is detected. Be sure to maintain a safe distance
between your vehicle and the vehicle ahead.
Always be aware which mode is selected.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.

STARTING AND OPERATING117
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor -
mance and extend transmission life by reducing
excessive shifting and heat build-up. This action
will also provide better engine braking.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate perfor -
mance and avoids frequent downshifts. For
example, choose “5” if the desired speed can be
maintained. Choose “4” or “3” if needed to
maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce vehicle
speed as necessary to avoid extended driving at
high RPM. Return to a higher gear or vehicle
speed when grade and road conditions allow.
RECREATIONAL TOWING
(BEHIND MOTORHOME)
Recreational towing (with all four wheels on the
ground, or using a tow dolly) is NOT ALLOWED. The
only acceptable method for towing this vehicle
(behind another vehicle) is on a vehicle trailer with
all four wheels OFF the ground.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Information in this section will aid in safe
controlled launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other
slippery surfaces may cause the driving wheels to
pull erratically to the right or left. This phenomenon
occurs when there is a difference in the surface
traction under the rear (driving) wheels.
Traction
When driving on wet or slushy roads, it is possible
for a wedge of water to build up between the tire
and road surface. This is known as hydroplaning
and may cause partial or complete loss of vehicle
control and stopping ability. To reduce this
possibility, the following precautions should be
observed:
Slow down during rainstorms or when the roads
are slushy.
Slow down if the road has standing water or
puddles.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine,
transmission and/or transfer case damage.
Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause sudden
pulling of the rear wheels. You could lose control
of the vehicle and possibly have a collision.
Accelerate slowly and carefully whenever there
is likely to be poor traction (ice, snow, wet, mud,
loose sand, etc.).

Launch Control

This vehicle is equipped with a Launch Control
system that is designed to allow the driver to
achieve quick, consistent 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 0-to-60 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 this system’s control resulting in an
aborted launch.
NOTE:
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 (805 km) of the vehicle’s life.

Launch Control should only be used when the engine
and transmission are at operating temperature.

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.

Launch Control is not available in ESC Full Off mode.

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and
brake performance under most braking conditions.
The system automatically prevents wheel lock, and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that
the ABS is working properly each time the vehicle
is started and driven. During this self-check, you
may hear a slight clicking sound as well as some
related motor noises.
The ABS is activated during braking when the
system detects one or more wheels are beginning
to lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic stops
may increase the likelihood of the ABS activating.
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may
continue to hear for a short time after the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of the
stopThe ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may
stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on
while driving, it indicates that the anti-lock portion
of the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the ABS Warning Light is on.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer
-
ence caused by improperly installed or high
output radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro -
planing.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.
WARNING!

SAFETY179
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of Anti-Lock Brakes. If the ABS
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Roll Mitigation
(ERM), Electronic Stability Control (ESC), Hill Start
Assist (HSA), and Traction Control System (TCS).
These systems work together to enhance both
vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Ready
Alert Braking (RAB) and Rain Brake Support (RBS).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or
comes on while driving, it indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to
prevent overslip of the rear wheels to avoid vehicle
instability, and to prevent the rear axle from
entering the Anti-Lock Brake System (ABS) before
the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, or striking
objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off”
mode (if equipped). For a complete explanation of
the available ESC modes, see Ú
page 180.
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.
