warning DODGE CHARGER 2021 Repair Manual

STARTING AND OPERATING101
When ACC Is Active:

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 a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.

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 appears
in the instrument cluster display. Distance Settings

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 ACC Set With Target
Detected Indicator Light, and the system will adjust the 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 99.
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.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

102STARTING AND OPERATING
Overtake Aid
When driving with Adaptive Cruise Control (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.
ACC Operation At Stop
In the event that the ACC system brings your
vehicle to a standstill while following the vehicle in
front, if the vehicle in front starts moving within two
seconds of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the ACC with Stop system will cancel and the
brakes will release. A cancel message will display
on the instrument cluster display and produce a
warning chime. Driver intervention will be required
at this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or the
driver door is opened, the ACC with Stop system
will cancel and the brakes will release. A cancel
message will display on the instrument cluster
display and produce a warning chime. Driver
intervention will be required at this moment.
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
the above message and the system will deactivate.
This message can sometimes be displayed while
driving in highly reflective areas (i.e. ice and snow,
or tunnels with reflective tiles). 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.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the center of the vehicle behind the lower grille.
To keep the ACC System operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market grilles. Doing so could cause an ACC
system failure or malfunction.
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.

21_LD_OM_EN_USC_t.book Page 102

STARTING AND OPERATING103
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” 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 and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield and fog on the inside of glass.
In these cases, the instrument cluster display will
display “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have
degraded performance.

This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/FCW
system will recover after the vehicle has left these
areas. Under rare conditions, when the camera is not
tracking any vehicles or objects in its path this warning
may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
mirror. They may require cleaning or removal of an
obstruction.

When the condition that created limited functionality
is no longer present, the system will return to full
functionality.

NOTE:
If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward
facing camera inspected at an authorized dealer.

SERVICE ACC/FCW WARNING

If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required” or
“Cruise/FCW Unavailable Service Required”, there may
be an internal system fault or a temporary malfunction
that limits ACC functionality. Although the vehicle is
still drivable under normal conditions, ACC will be
temporarily unavailable. If this occurs, try activating
ACC again later, following an ignition cycle. If the
problem persists, see an authorized dealer.

Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER

Towing a trailer is not recommended when using ACC.

OFFSET DRIVING

ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be sufficient
distance to the vehicle ahead. The offset vehicle may
move in and out of the line of travel, which can cause
your vehicle to brake or accelerate unexpectedly.

Offset Driving Condition Example

21_LD_OM_EN_USC_t.book Page 103

STARTING AND OPERATING105
NARROW VEHICLES

Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until
they have moved fully into the lane. There may not be
sufficient distance to the vehicle ahead.

Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not react
in situations where the vehicle you are following
exits your lane and the vehicle ahead is stopped in
your lane. Always be attentive and ready to apply
the brakes if necessary.
Stationary Object And Stationary Vehicle Example

PARKSENSE REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Rear Park Assist system provides
visual and audible indications of the distance
between the rear fascia/bumper and a detected
obstacle when backing up (e.g. during a parking
maneuver).
For limitations of this system and
recommendations, see Ú
page 108.
ParkSense will retain the system state (enabled or
disabled) from the previous ignition cycle when the
ignition is changed to the ON/RUN position.
ParkSense can be active only when the gear selector is
in REVERSE. If ParkSense is enabled at this gear
selector position, the system will remain active until the
vehicle speed is increased to approximately 7 mph
(11 km/h) or above. The system will become active
again if the vehicle speed is decreased to speeds less
than approximately 6 mph (9 km/h).

PARKSENSE SENSORS

The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/bumper.
These distances depend on the location, type and
orientation of the obstacle in the horizontal direction.

PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE and
an obstacle has been detected.
The system will indicate a detected obstacle by
showing a single arc in the left and/or right front or
rear regions based on the object’s distance and
location relative to the vehicle.

rear fascia/bumper and the detected obstacle.

ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled
with the ParkSense switch.

When the ParkSense switch is pushed to disable
the system, the instrument cluster will display
the “ParkSense Off” message for approximately
five seconds. When the gear selector is moved to
REVERSE and the system is disabled, the instrument
cluster display will display the “ParkSense Off”
message for as long as the vehicle is in REVERSE.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service. The
ParkSense switch LED will be off when the system is
enabled. If the ParkSense switch is pushed and the
system requires service, the ParkSense switch LED
will blink momentarily and then the LED will be on.

SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM

During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the
instrument cluster display will actuate a single chime,
once per ignition cycle, and it will display the
“PARKSENSE UNAVAILABLE WIPE REAR SENSORS” or
the “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message. When the gear selector is moved to REVERSE
and the system has detected a faulted condition, the
instrument cluster display will show the "PARKSENSE
UNAVAILABLE WIPE REAR SENSORS" or "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" message for as
long as the vehicle is in REVERSE. Under this condition,
ParkSense will not operate.

If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” appears in the instrument cluster
display, make sure the outer surface and the
underside of the rear fascia/bumper is clean and
clear of snow, ice, mud, dirt or other obstruction and
then cycle the ignition. If the message continues to
appear, see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE
REQUIRED” appears in the instrument cluster
display, see an authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the rear fascia/bumper is free of
snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.

Jackhammers, large trucks, and other vibrations
could affect the performance of ParkSense.

When you turn ParkSense off in DRIVE, the
instrument cluster will display "PARKSENSE
OFF" for five seconds. Furthermore, once you
turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.

21_LD_OM_EN_USC_t.book Page 108

STARTING AND OPERATING109
When you move the gear selector to the
REVERSE position and ParkSense is turned off,
the instrument cluster display will show the
“PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
ParkSense will reduce the volume of the radio
when it is sounding an audio tone.

Clean the ParkSense sensors regularly, taking care
not to scratch or damage them. The sensors must
not be covered with ice, snow, slush, mud, dirt or
debris. Failure to do so can result in the system not
working properly. The ParkSense system might not
detect an obstacle behind the fascia/bumper, or it
could provide a false indication that an obstacle is
behind the fascia/bumper.

Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers,
trailer hitches, etc. are placed within 12 inches
(30 cm) from the rear fascia/bumper. Failure to
do so can result in the system misinterpreting a
close object as a sensor problem, causing the
“PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” message to be displayed in the
instrument cluster.
LANESENSE — IF EQUIPPED
LANESENSE OPERATION
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). The LaneSense system uses a
forward looking camera to detect lane markings
and measure vehicle position within the lane
boundaries.

When both lane markings are detected and the driver
unintentionally drifts out of the lane (no turn signal
applied), the LaneSense system provides a haptic
warning in the form of torque applied to the steering
wheel to prompt the driver to remain within the lane
boundaries. If the driver unintentionally drifts out of the
lane, the LaneSense system provides a visual warning
through the instrument cluster display to prompt the
driver to remain within the lane boundaries.

The driver may manually override the haptic
warning by applying torque to the steering wheel at
any time.
When only a single lane marking is detected and
the driver drifts across the lane marking (no turn
signal applied), the LaneSense system provides
visual warnings through the instrument cluster
display to prompt the driver to remain within the
lane. When only a single lane marking is detected,
a haptic or a torque warning will not be provided.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety
and must continue to pay attention to your
surroundings. 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 recom -
mended that the driver looks over his/her
shoulder when using ParkSense.

110STARTING AND OPERATING
NOTE:
When operating conditions have been met, the Lane -
Sense system will monitor if the driver’s hands are on
the steering wheel and provide an audible warning to
the driver if removed. The system will cancel if the
driver does not return their hands to the wheel.

TURNING LANESENSE ON OR OFF
The LaneSense button is located on the
center stack below the Uconnect display.
To turn the LaneSense system on, push the
LaneSense button (LED turns off). A “LaneSense

state, on or off, from the last ignition cycle when
the ignition is placed in the ON/RUN position.
LANESENSE WARNING MESSAGE
The LaneSense system will indicate the current
lane drift condition through the instrument cluster
display. Premium Instrument Cluster Display
When the LaneSense system is on, the lane lines
are gray when both of the lane boundaries have
not been detected and the LaneSense telltale is
solid white.

System On (Gray Lines/White Telltale)

Left Lane Departure — Only Left Lane Detected

When the LaneSense system is on, the LaneSense
telltale is solid white when only the left lane marking
has been detected and the system is ready to
provide visual warnings in the instrument cluster
display if a lane departure occurs.

When the LaneSense system senses the lane has
been approached and is in a lane departure situ-
ation, the left lane line flashes yellow (on/off),
and the LaneSense telltale changes from solid
white to flashing yellow.
Lane Approached With Flashing Yellow Line/Flashing Yellow Telltale

NOTE:The LaneSense system operates with similar
behavior for a right lane departure when only the
right lane marking has been detected.

21_LD_OM_EN_USC_t.book Page 110

STARTING AND OPERATING111
Left Lane Departure — Both Lanes Detected
When the LaneSense system is on, the lane
lines turn from gray to white to indicate that
both of the lane markings have been detected.
The LaneSense telltale is solid green when both
lane markings have been detected and the
system is “armed” to provide visual warnings in
the instrument cluster display and a torque
warning in the steering wheel if an unintentional
lane departure occurs.

Lanes Sensed (White Lines/Green Telltale)

When the LaneSense system senses a lane drift
situation, the left lane line turns solid yellow.
The LaneSense telltale changes from solid
green to solid yellow. At this time torque is
applied to the steering wheel in the opposite
direction of the lane boundary.
For example, if approaching the left side of the
lane the steering wheel will turn to the right.

Lane Drift With Solid Yellow Line/Solid Yellow Telltale
When the LaneSense system senses the lane has
been approached and is in a lane departure situa -
tion, the left lane line flashes yellow (on/off).
The LaneSense telltale changes from solid yellow to
flashing yellow. At this time torque is applied to the
steering wheel in the opposite direction of the lane
boundary.

For example, if approaching the left side of the
lane the steering wheel will turn to the right.
