2014 JEEP GRAND CHEROKEE Owners Manual

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 atone. 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.

Enabling And Disabling ParkSense®
ParkSense® can be enabled and disabled with the
ParkSense® switch.
When the ParkSense® switch is pressed to dis-
able the system, the instrument cluster will dis-
play the “PARKSENSE OFF” message for ap-
proximately five seconds. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information. When the
shift lever/gear selector is moved to REVERSE and the
system is disabled, the EVIC 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 “Electronic Vehicle Information Center
(EVIC). When the shift lever/gear selector is moved to
REVERSE and the system has detected a faulted condi-
tion, the EVIC will display the PARKSENSE 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 Electronic Vehicle Information
Center (EVIC) 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 EVIC, 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 EVIC will
display “PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
220 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•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
EVIC. •
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.
• 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.
