2015 JEEP GRAND CHEROKEE warning

FCW Limited Warning
If the system turns off, and the DID displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited Function-
ality Clean Front Windshield” momentarily, there may be
a condition that limits FCW functionality. Although the
vehicle is still drivable under normal conditions, the
active braking may not be fully available. Once the
condition that limited the system performance is no
longer present, the system will return to its full perfor-
mance state. If the problem persists, see your authorized
dealer.
Service FCW Warning
If the system turns off, and the DID displays:
•ACC/FCW Unavailable Service Required
•Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
PARKSENSE® REAR PARK ASSIST — IF
EQUIPPED
The ParkSense® Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense® System
Usage Precautions for limitations of this system and
recommendations.
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 shift lever/gear
selector is in REVERSE. If ParkSense® is enabled at this
shift lever/gear selector position, the system will remain

active until the vehicle speed is increased to approxi-
mately 7 mph (11 km/h) or above. When in REVERSE
and above the system’s operating speed, a warning will
appear within the Driver Information Display (DID)
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 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 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
ParkSense® Warning Display
The ParkSense® Warning screen will only be displayed if
Sound and Display is selected from the Customer -

tem. Refer to#Uconnect® Settings” in “Understanding
Your Instrument Panel” for further information.
The ParkSense® Warning screen is located within the
DID. It provides visual warnings to indicate the distance
between the rear fascia/bumper and the detected ob-
stacle. Refer to “Driver Information Display (DID)” for
further information.

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.
(Continued)
WARNING!(Continued)
•Before using ParkSense®, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is 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 loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.

PARKSENSE® FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense® Park Assist system provides visual and

Refer to ParkSense® System Usage Precautions for limi-
tations of this system and recommendations.
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 shift lever is in
REVERSE or DRIVE. If ParkSense® is enabled at one of
these shift lever positions, the system will remain active
until the vehicle speed is increased to approximately
7 mph (11 km/h) or above. A display warning will
appear in the Driver Information Display (DID) indicat-
ing the vehicle is above ParkSense® operating speed. 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 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
The six ParkSense® sensors, located in the front fascia/
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 in (30 cm) up to 47 in
(120 cm) from the front fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
