2021 CHRYSLER 300 ignition

100 STARTING AND OPERATING
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
s y

stem 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.
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 also a chime
will indicate 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
d
r

iving 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
s h

ould 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
f u

nctionality is no longer present, the system will
return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front
W i
ndshield” 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.

STARTING AND OPERATING 103
PARKSENSE FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear and/or front fascia/bumper and a
detected obstacle when backing up or moving
forward (e.g. during a parking maneuver).
For limitations of this system and
re

commendations, see Ú page 107.
ParkSense will retain the system state (enabled or
d i

sabled) from the previous ignition cycle when the
ignition is changed to the ON/RUN position.
ParkSense can be active only when the gear
s e

lector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(1

1 km/h) or above. The system will become active
a g
ain 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 th
e rear fascia/bumper. These distances depend
on the location, type, and orientation of the
obstacle in the horizontal direction.
The six ParkSense sensors, located in the front
f a

scia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view. The
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
th

e front 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, or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
sh
owing a single arc in one or more regions based
on the obstacle’s distance and location relative to
the vehicle.
If an obstacle is detected in the center rear region,
th
e display will show a single solid arc in the center
rear region and will produce a one-half second
tone. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to
the vehicle and the tone will change from slow, to
fast, to continuous. If an obstacle is detected in the left and/or right
r
e

ar region, the display will show a single flashing
arc in the left and/or right rear region and will
produce a fast sound tone. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the tone
will change from fast to continuous.
If an obstacle is detected in the center front region,
t h

e display will show a single arc in the center front
region. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to
the vehicle. A fast sound tone will be produced
when reaching the second flashing arc and will
change to a continuous tone when the first flashing
arc appears.
If an obstacle is detected in the left and/or right
f r

ont region, the display will show a single flashing
arc in the left and/or right front region and will
produce a fast tone. As the vehicle moves closer to
the obstacle, the display will show the single arc
moving closer to the vehicle and the tone will
change from fast to continuous.

SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or the "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" message for
five seconds. When the gear selector is moved to
REVERSE and the system has detected a faulted
condition, the instrument cluster display will
display a "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE FRONT SENSORS" or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" pop-up message for five
seconds. After five seconds, a vehicle graphic will
be displayed with "UNAVAILABLE" at either the
front or rear sensor location depending on where
the fault is detected. The system will continue to
provide arc alerts for the side that is functioning
properly. These arc alerts will interrupt the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" messages if an object is
detected within the five second pop-up duration.
The vehicle graphic will remain displayed for as
long as the vehicle is in REVERSE.
If "PARKSENSE UNAVAILABLE WIPE REAR
S
E

NSORS" or "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" appears in the instrument
cluster display make sure the outer surface and
the underside of the rear fascia/bumper and/or
front 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 the "PARKSENSE UNAVAILABLE SERVICE
R E

QUIRED" message 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 front and rear bumpers are free
of snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.
When you turn ParkSense off, the instrument
cluster will display “PARKSENSE OFF.” Once you
turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
When you move the gear selector to the
REVERSE position and ParkSense is turned off,
the instrument cluster will display “PARKSENSE
OFF” for as long as the vehicle is in REVERSE.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a 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 or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of 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
(3

0 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 SERVICE
REQUIRED” message to be displayed in the
instrument cluster.
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.
Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
a s
sembly be disconnected from the vehicle
when the vehicle is not used for towing.
Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia/bumper when the vehicle sounds
the continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the
vehicle.
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
s h

oulder when using ParkSense.

LANESENSE — IF EQUIPPED
LANESENSE OPERATION
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
( 1
80 km/h). The LaneSense system uses a
f or
ward looking camera to detect lane markings
and measure vehicle position within the lane
boundaries.
When both lane markings are detected and the
dr
iver 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
w a

rning by applying torque into the steering wheel
at any time.
When only a single lane marking is detected and
t h

e driver unintentionally 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 (torque) warning will
not be provided.
NOTE:
When operating conditions have been met, the
La n
eSense 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.

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
th

e 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
s y

stem 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 ABS activation(s).
You also may experience the following normal
c h

aracteristics 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
stop. The ABS is designed to function with the Original
E
q

uipment 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
w h

ile 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 Anti-Lock Brake Warning Light is on.
If the ABS Warning Light is on, the brake system
s h

ould be serviced as soon as possible to restore
the benefits of Anti-Lock Brakes. If the Anti-Lock
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer -
ence caused by improperly installed or high
out
put 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.
