2021 CHRYSLER 300 park assist

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.

106 STARTING AND OPERATING
Front Park Assist Audible Alerts
ParkSense will turn off the Front Park Assist
au

dible alert (chime) after approximately three
seconds when an obstacle has been detected, the
vehicle is stationary, and brake pedal is applied.
Adjustable Chime Volume Settings
Front and Rear chime volume settings can be
s e

lected in the Uconnect system Ú page 122.
The chime volume settings include low, medium,
a n

d high.
ParkSense will retain its last known configuration
st
ate through ignition cycles.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be
displayed if Sound and Display is selected from
within the Uconnect system
Ú page 122.
The ParkSense Warning screen is located within
t h

e instrument cluster display Ú page 66. It
provides visual warnings to indicate the distance
b e
tween the rear fascia/bumper and/or front
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
t
h

e 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 will display the “ParkSense Off”
message for as long as the vehicle is in REVERSE.
The ParkSense switch LED will be on when
P a

rkSense 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
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.

as
soon as possible to have the problem
diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light
s t

arts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when TCS is active. If the ESC Activation/
Malfunction Indicator Light begins to flash during
acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the
El

ectronic Stability Control (ESC) in a
reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON position.
Each time the ignition is placed in the ON posi -
tion, the ESC system will be on even if it was
t u
rned off previously.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a
complete stop while on an incline. If the driver
releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a
short period. If the driver does not apply the
throttle before this time expires, the system will
release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for
HS A

to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK or NEUTRAL. For vehicles
e q

uipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting using Uconnect
Settings, see
Ú page 122 for further information.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.

142 SAFETY
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup on
the front brake rotors. It functions when the windshield wipers are in LO or HI speed. When RBS
is active, there is no notification to the driver and
no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Controller (EBC) will prepare the brake system for
a panic stop.
Traction Control System (TCS)
TCS monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the
TCS may apply brake pressure to the spinning
wheel(s) and/or reduce engine power to provide
enhanced acceleration and stability. A feature of
the TCS, Brake Limited Differential (BLD) functions
similarly to a limited slip differential and controls
the wheel spin across a driven axle. If one wheel on
a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel.
This will allow more engine torque to be applied to
the wheel that is not spinning. BLD may remain
enabled even if TCS and Electronic Stability Control
(ESC) are in reduced modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —

I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light
wi
ll momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear or
REVERSE.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
a p

ply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle.
Also, be certain to place the transmission in
PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.

194 IN CASE OF EMERGENCY
ALL WHEEL DRIVE (AWD) MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If the transmission and driveline are operable,
AW
D models can also be towed with the ignition in
the ON/RUN mode, the transmission in NEUTRAL
(N) (not in PARK!), and the rear wheels OFF the
ground with no limitation on speed or distance.
Since the ignition MUST be in the ON/RUN mode to
tow in this manner, AWD vehicles must be towed
with ALL FOUR wheels OFF the ground (e.g. on a
flatbed truck) if the key fob is unavailable.
REAR WHEEL DRIVE (RWD) MODELS
FCA LLC US recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the
tr
ansmission is operable, this vehicle may be flat
towed (with all four wheels on the ground) under
the following conditions:
The transmission must be in NEUTRAL (N).
Instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú page 190.
The towing speed must not exceed 30 mph
(4
8 km/h).
The towing distance must not exceed 30 miles
(4
8 km).
If the transmission is not operable, or the vehicle
m u

st be towed faster than 30 mph (48 km/h) or
f a
rther than 30 miles (48 km), then the only
a c
ceptable method of towing is with a flatbed
truck.
