light DODGE CHALLENGER 2021 Service Manual

84STARTING AND OPERATING
NOTE:During cold weather, you may experience
increased effort in shifting until the transmission
fluid warms up. This is normal.

Manual Gear Selector

SHIFTING
Fully press the clutch pedal and lift your foot off the
accelerator pedal before shifting gears. As you
release the clutch pedal, lightly press the
accelerator pedal. Damage to the transmission or
clutch may occur if you do not fully press the clutch
pedal and lift off of the accelerator pedal when
shifting.
Shift Pattern
The six-speed manual transmission has a spring
that centers the gear selector near THIRD and
FOUTH gear. This spring helps you know which gear
you are in when you are shifting. Be careful when
shifting from FIRST to SECOND or downshifting
from SIXTH to FIFTH.
The spring will try to pull the gear selector toward
THIRD and FOURTH gear. Make sure you move the
gear selector into SECOND or FIFTH gear. If you let
the gear selector move in the direction of the
pulling, you may end shifting from FIRST to
FOURTH or from SIXTH to THIRD gear.
You must always use FIRST gear (or REVERSE)
when starting from a standing position.Failure to press the clutch pedal fully to the
floor may cause increased shift efforts, and
may result in damage to the clutch and trans
-
mission.
Do not rest your hand on the gear selector
while driving, as this may result in transmis -
sion synchronizer damage.
Do not attempt to shift the transmission if the
rear wheels are spinning due to loss of trac -
tion. Damage to the transmission may occur.
CAUTION!
CAUTION!
Always make sure the vehicle comes to a
complete stop before shifting into REVERSE.
Failure to do so may result in transmission
damage.

STARTING AND OPERATING85
RECOMMENDED SHIFT SPEEDS
To utilize your manual transmission efficiently for fuel economy, it should be upshifted as listed in recommended shift speed chart.
Earlier upshifts during cruise conditions (relatively steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired acceleration rate.
NOTE:
Your vehicle is equipped with a transmission reverse inhibitor system. Always depress the clutch pedal fully to the floor before shifting into REVERSE. When
vehicle speed is greater than 3 mph (5 km/h), the reverse inhibitor activates to help prevent shifts into REVERSE. When at a complete stop, you may notice
lighter shift efforts into REVERSE with the ignition switch in the ON position (RUN position for Keyless Enter ‘n Go™), as compared to the ignition LOCK position
(OFF position for Keyless Enter ‘n Go™). This is normal operation of the transmission reverse inhibitor system.
Due to the high performance nature of your drivetrain, you may hear your transmission. This can be most noticeable when the vehicle is idling in NEUTRAL
with the clutch engaged (clutch pedal released), but it may also be heard when driving at low engine RPM. Also, this may be more noticeable when the trans -
mission is warm. This is a normal condition and is not an indication of a problem with your clutch or transmission.

90STARTING AND OPERATING
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.
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.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), use
the AutoStick shift control to select a lower gear
Úpage 91. Under these conditions, using a lower
gear will improve performance and extend
transmission life by reducing excessive shifting
and heat build-up.
During cold temperatures, transmission operation
may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch is inhibited until the transmission fluid is
warm. Normal operation will resume once the
transmission temperature has risen to a suitable
level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting (also known as AutoStick
mode Ú page 91. 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 abnormal 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: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.
For Recreational Towing Ú page 117.
For Towing A Disabled Vehicle Ú page 244.

21_LA_OM_EN_USC_t.book Page 90

STARTING AND OPERATING91
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 location (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
recommend 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 providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This system can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
In AutoStick mode, you can use the gear selector
(in the MANUAL position), or the shift paddles to
the MANUAL (M) position (beside the DRIVE (D)
position), or tap one of the shift paddles on the
steering wheel. Tapping the (-) shift paddle to enter
AutoStick mode will downshift the transmission to
the next lower gear, while tapping (+) to enter
AutoStick mode will retain the current gear. The
current transmission gear will be displayed in the
instrument cluster.
Shifter Paddles

NOTE:
Tapping one of the steering wheel-mounted
shift paddles (+/-) (if equipped), 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 tapping (+) to enter AutoStick
mode will retain the current gear. The current
gear will be displayed in the instrument cluster,
but the “M” will not be highlighted. The trans
-
mission will revert back to normal operation (if
the gear selector remains in DRIVE) after a
period of time, depending on accelerator pedal
activity.

STARTING AND OPERATING93
NOTE:If equipped with a manual transmission, the 1 - 4
Skip Shift Feature is disabled in SPORT Mode.
FUEL SAVER TECHNOLOGY 5.7L —
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. When the system is active,
an indication will display within the instrument
cluster “Fuel Economy” main menu screen.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
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
Ú
page 120.
If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEERING” or
the “POWER STEERING ASSIST OFF – SERVICE
SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for service
Ú page 69.
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, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service. If the Steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is
displayed on the instrument cluster screen, they
indicate that extreme steering maneuvers may
have occurred which caused an over temperature
condition in the power steering system. Once
driving conditions are safe, pull over and let the
vehicle idle for a few moments until the icon and
message turn off.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main
-
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

STARTING AND OPERATING95
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust until the button is
released, then the new set speed will be estab -
lished.
To Accelerate For Passing
While the Cruise Control system is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise 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 Cruise Control.
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 tap on the brake pedal, pushing the CANC button,
or normal brake pressure will deactivate the Cruise
Control system without erasing the set speed from
memory.
Pushing the on/off button or placing the ignition in
the OFF position erases the set speed from
memory. The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Clutch pedal is pressed (manual transmission
only)
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently
Ú page 94.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
utilizes a radar sensor and a forward facing
camera designed to detect a vehicle directly ahead
of you to maintain a set speed.
WARNING!
Cruise 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 Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

STARTING AND OPERATING99
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
While ACC is set, you can increase speed by
pushing the SET (+) button, or decrease speed by
pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active:
NOTE:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system applies the brake down to
15 mph (24 km/h) when following a vehicle
ahead.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting will show in the instrument cluster display.

Distance Settings

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
4

21_LA_OM_EN_USC_t.book Page 99

100STARTING AND OPERATING
To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the Adaptive Cruise
Control (ACC) Set With Target Vehicle Light, and the
system adjusts vehicle speed automatically to
maintain the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú page 97.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will flash in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
Overtake Aid
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn
signal and will only be active when passing on the
left hand side.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and a chime will
sound when conditions temporarily limit system
performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system may
also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
“ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e. tunnels
with reflective tiles, or ice and snow). The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.

WARNING!
Drivers must be careful when backing up even
when using the ParkView Rear Back Up Camera.
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!
To avoid vehicle damage, ParkView should
only be used as a parking aid. The ParkView
camera is unable to view every obstacle or
object in your drive path.
To avoid vehicle damage, the vehicle must be
driven slowly when using ParkView to be able
to stop in time when an obstacle is seen. It is
recommended that the driver look frequently
over his/her shoulder when using ParkView.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

The bar code allows a computer scanner to read
the VIN.
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, and
cargo. The total load must be limited so that you do
not exceed the GVWR.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impuri -
ties into the fuel system.
A poorly fitting fuel filler cap may cause the
Malfunction Indicator Light to turn on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel tank
is full.
