2016 JEEP GRAND CHEROKEE Owners Manual

FCW Limited Warning
If the DID displays “ACC/FCW Limited Functionality”
or “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 sys-
tem performance is no longer present, the system will
return to its full performance state. If the problem per-
sists, 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. If your vehicle is equipped
with an Automatic Transmission, the vehicle brakes may
be automatically applied and released when performing
a reverse parking maneuver if the system detects a
possible collision with an obstacle.
NOTE:
• The driver can override the automatic braking func-
tion by pressing the gas pedal, turning ParkSense off
via ParkSense switch, or changing the gear while the
automatic brakes are being applied.
• Automatic brakes will not be available if ESC is not
available.

•Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
• The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid collid-
ing with a detected obstacle.
• The automatic braking function may not be applied
fast enough for obstacles that move toward the rear of
the vehicle from the left and/or right sides.
• The automatic braking function can be enabled/
disabled from the Customer-Programmable Features
section of the Uconnect System.
• ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles. The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected ob-
stacles when backing up in REVERSE gear.
NOTE:
•
The driver is always responsible for controlling the
vehicle.
• The system is provided 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.
Refer to ParkSense System Usage Precautions for limita-
tions 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 gear selector is in
REVERSE. If ParkSense is enabled at this gear selector
position, 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 oper-
ating 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 approxi-
mately 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 -
Programmable Features section of the Uconnect System.
Refer toUconnect 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.

ParkSense Display
When the vehicle is in REVERSE and an obstacle has
been detected, the warning display will turn ON indicat-
ing the system status.The system will indicate a detected obstacle by showing
a single arc in the left and/or right rear regions based on
the obstacle’s distance and location relative to the vehicle.
If an obstacle 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 obstacle, 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.
