2018 CHRYSLER PACIFICA service

“Normal (Fixed Speed) Cruise Control Mode” in this
section.
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 malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion. 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 obstruc-
tion, have the radar sensor realigned at your authorized
dealer.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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, driving directly into the
sun and fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW Limited
Functionality Clean Front Windshield” and the system will
have degraded performance.
344 STARTING AND OPERATING

The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 rear view 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 your 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 temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your 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.
Towing A Trailer
Towing a trailer is not advised when using ACC.

STARTING AND OPERATING 345

Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with the
ParkSense switch, located on the switch panel
below the Uconnect display.
When the ParkSense switch is pushed to disable the
system, the instrument cluster will display the
“PARKSENSE OFF” message for approximately five sec-
onds. Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
When the gear selector is moved to REVERSE and the
system is disabled, the instrument cluster display will
show 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 requires service, the ParkSense switch LED will
blink momentarily, and then the LED will be on.
NOTE: When KeySense feature is present, the ParkSense
System will reject customer input to turn the system off via
the hard switch. The instrument cluster display will show
KeySense in Use Selected Feature Cannot be Disabled 
message.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster will actuate a single chime, once per ignition
cycle, and it will display the “PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS” or the “PARKSENSE UN-
AVAILABLE SERVICE REQUIRED” message. Refer to “In-
strument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information. 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 SEN-
SORS orPARKSENSE UNAVAILABLE SERVICE RE-
QUIRED message for five seconds while the vehicle is in
REVERSE. Under this condition, ParkSense will not oper-
ate and “PARKSENSE OFF” message will be displayed.
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 obstruc-
tion and then cycle the ignition. If the message continues to
appear, see an authorized dealer.
358 STARTING AND OPERATING

If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the instrument cluster display, see an autho-
rized 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 Precautions
NOTE:
•Ensure that the rear 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, the instrument cluster
will display “PARKSENSE OFF”. Furthermore, 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 display will show “PARKSENSE OFF” message
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 the fascia/bumper, or it could provide a
false indication that an obstacle is behind the fascia/
bumper.
• ParkSense should be disabled when the liftgate is in the
open position.
• 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 SERVICE
REQUIRED” message to be displayed in the instrument
cluster display.

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.

• ParkSense should be disabled when the liftgate is in the
open position.
• 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.
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,
