2021 CHRYSLER PACIFICA warning

STARTING AND OPERATING155
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 show
“ACC/AEB Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/AEB Unavailable Wipe Front Radar
Sensor” 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/AEB 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.
NOTE:If the “ACC/AEB 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.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/AEB 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, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/AEB
Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
The “ACC/AEB Limited Functionality Clean Front
Windshield” 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/AEB 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.

156STARTING AND OPERATING
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

TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no vehicle in
front detected. Once the vehicle is out of the curve
the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.
Turn Or Bend Example

21_RUP_OM_EN_USC_t.book Page 156

STARTING AND OPERATING159
NOTE:
The system is designed to assist the driver and
not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking, and is
responsible for the vehicle's movements.
For limitations of this system and
recommendations, see Ú page 163.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is changed to the ON/RUN
position.
ParkSense can be active only when the gear
selector 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
(11 km/h) or above. When in REVERSE and above
the system's operating speed, a warning will
appear in the instrument cluster display indicating
the vehicle speed is too fast. 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 six ParkSense sensors (four when vehicle is
not equipped with front sensors), located in the
rear fascia/bumper, and the six ParkSense
sensors located in the front fascia/bumper,
monitor the area in front and behind the vehicle
that is within the sensors’ field of view. The front
sensors detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper. The rear 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.

Rear Sensor Locations

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
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.
If an object is detected in the left and/or right rear
region, the display will show a single arc in the left
and/or right rear region and the system will
produce a tone. As the vehicle moves closer to the
object, the display will show the single arc moving
closer to the vehicle and the tone will change from
a single 1/2 second tone to slow, to fast, to
continuous.

164STARTING AND OPERATING
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 appropriate fascia/
bumper, or it could provide a false indication
that an obstacle is behind or in front of the
appropriate 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.
ParkSense should be disabled when the liftgate
is in the open position. An opened liftgate could
provide a false indication that an obstacle is
behind the vehicle.
There may be a delay in the object detection
rate if the object is moving. This may cause the
automatic braking application to be delayed.
PARKSENSE ACTIVE PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Active Park Assist system is
intended to assist the driver during parallel and
perpendicular parking maneuvers by identifying a
proper parking space, providing audible/visual
instructions, and controlling the steering wheel.
The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver
maintains control of the accelerator, gear selector
and brakes.
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
assembly 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 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
shoulder when using ParkSense.

21_RUP_OM_EN_USC_t.book Page 164

168STARTING AND OPERATING
The system will cancel the maneuver if the
vehicle speed exceeds 5 mph (7 km/h) during
active steering guidance into the parking space.
The system will provide a warning to the driver
at 3 mph (5 km/h) that tells them to slow down.
The driver is then responsible for completing the
maneuver if the system is canceled.
If the system is canceled during the maneuver
for any reason, the driver must take control of
the vehicle.
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). It 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 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,
as well as a visual warning in the instrument
cluster display, to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying force into the steering wheel at
any time.
When only a single lane marking is detected and
the driver unintentionally drifts across that lane
marking (no turn signal applied), the LaneSense
system provides a visual warning 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.
NOTE:When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provide an
audible and visual warning to the driver when the
driver’s hands are not detected on the steering
wheel. The system will cancel if the driver does not
return their hands to the wheel.
WARNING!
Drivers must be careful when performing
parallel or perpendicular parking maneuvers
even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and in
front of you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up
and moving forward. 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!
The ParkSense Active Park Assist system 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
the ParkSense Active Park Assist system in
order to be able to stop in time when an
obstacle is detected. It is recommended that
the driver looks over his/her shoulder when
using the ParkSense Active Park Assist
system.

left lane marking has been detected and the
system is ready to provide visual warnings in the
instrument cluster display if an unintentional
lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane departure
situation, the visual warning in the instrument
cluster display will show the left inside lane line
flashing yellow (on/off), while the outside lane
line on the left of the display will remain solid
yellow. The LaneSense telltale changes from
solid white to flashing yellow.
