2015 JEEP GRAND CHEROKEE sensor

Enabling And Disabling ParkSense®
ParkSense® can be enabled and disabled with the
ParkSense® switch.
When the ParkSense® switch is pressed to disable
the system, the instrument cluster will display the
“PARKSENSE OFF” message for approximately
five seconds. Refer to “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel” for
further information. When the shift lever/gear selector is
moved to REVERSE and the system is disabled, the DID will
display 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 pressed, and the system requires service, the
ParkSense® switch LED will blink momentarily, and then
the LED will be ON.
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 shift lever/gear selector is
moved to REVERSE and the system has detected a
faulted condition, the DID will display the#PARKSENSE
UNAVAILABLE WIPE REAR SENSORS#or
#PARKSENSE UNAVAILABLE 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 oper-
ating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®.
•When you turn ParkSense® OFF, the instrument clus-
ter 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 key.
•When you move the shift lever 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.
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
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
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.

five seconds. After five seconds, a car graphic will be
displayed with#UNAVAILABLE#at either the front or
rear sensor location depending on where the fault is
detected. The system will continue to provide arc alerts
for the side that is functioning properly. These arc alerts
will interrupt the#PARKSENSE UNAVAILABLE WIPE
REAR SENSORS#,#PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS#,or#PARKSENSE UNAVAILABLE
SERVICE REQUIRED#messages if an object is detected
within the five second pop-up duration. The car graphic
will remain displayed for as long as the vehicle is in
REVERSE. Refer to “Driver Information Display (DID)”
for further information.
If#PARKSENSE UNAVAILABLE WIPE REAR SENSORS#
