2016 JEEP GRAND CHEROKEE sensor

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.

Service The ParkSense Rear Park Assist System
During vehicle start up, when the ParkSense Rear Park
Assist 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” or the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message. Refer to “Driver Information Display (DID)” for
further information. When the gear selector is moved to
REVERSE and the system has detected a faulted condi-
tion, the DID will display thePARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS orPARKSENSE UN-
AVAILABLE SERVICE REQUIRED message for as long
as the vehicle is in REVERSE. Under this condition,
ParkSense will not operate.
If “PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS” appears in the Driver Information Display (DID)
make sure the outer surface and the underside of the rear
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 “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the DID, see an authorized 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 dam-
age 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.
230 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•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 DID will
display “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. •
Use the ParkSense switch to turn the ParkSense system
OFF if objects such as bicycle carriers, trailer hitches,
etc. are placed within 12 in (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 DID.
• ParkSense should be disabled when the liftgate is in
the open position and the vehicle is in REVERSE. An
open liftgate could provide 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 recommended that the
driver looks over his/her shoulder when using
ParkSense.
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.
(Continued)
WARNING! (Continued)
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 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.
