2010 JEEP GRAND CHEROKEE Owners Manual

ParkSensewill remember the last system state (enabled
or disabled) from the last ignition cycle when the ignition
is changed to the ON position.
ParkSense can be active only when the shift lever is in
REVERSE. If ParkSense is enabled at this shift lever
position, the system will be active until the vehicle speed
is increased to approximately 11 mph (18 km/h) or
above. The system will be active again if the vehicle
speed is decreased to speeds less than approximately
10 mph (16 km/h).
ParkSense Sensors
The four ParkSense sensors, located in the rear fascia,
monitor the area behind the vehicle that is within the
sensors’ field of view.
The sensors can detect obstacles from approximately 12
to 59 in (30 to 150 cm) from the rear fascia in the
horizontal direction, depending on the location and
orientation of the obstacle and the type of obstacle.
ParkSense Warning Display
The ParkSense warning display, located in the headliner
near the flipper glass, provides both visible and audible
warnings to indicate the distance between the rear fascia
and the detected obstacle.
ParkSense Display

When the ignition is turned to the ON position, the
warning display will turn ON all of its LEDs for about
one second. Each side of the warning display has six
yellow and two red LEDs. The vehicle is close to the
obstacle when the red LED is ON.The system dimly illuminates the two outer most yellow
LEDs when it is ON and detecting no obstacles. The
following chart shows the warning display operation
when the system is detecting an obstacle:

radio, if on, when the system is sounding an audio tone.
Enable/Disable ParkSense
ParkSense can be enabled and disabled with a switch
located on the upper switch bank of the instrument
panel.
Press the switch once to turn ParkSense on,
push the switch a second time to turn Park-
Sense off.
When the switch is pressed to disable the system, the
instrument cluster will display the “PARK ASSIST DIS-
ABLED” message. Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understanding Your Instrument
Panel” for further information. When the shift lever is
changed to REVERSE and the system is disabled, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display the message. The ParkSense
switch LED will be ON when the system
is disabled or defective. The ParkSense switch LED will
be OFF when the system is enabled.Service ParkSense
When ParkSense is defective, the instrument cluster will
actuate a single chime, once per ignition cycle, and it will
display the “SERVICE PARK ASSIST SYSTEM” message.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information. If “SERVICE PARK ASSIST SYSTEM” ap-
pears in the EVIC after making sure the rear fascia/
bumper is clean and free of snow, ice, mud, or other
debris, see your authorized dealer.
Cleaning ParkSense
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.

System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep ParkSenseoperating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSense off, the instrument cluster
will display “PARK ASSIST DISABLED.” Further-
more, 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 instrument
cluster will display “PARK ASSIST DISABLED” mes-
sage for as long as the vehicle is in REVERSE.
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•If a ParkSense system malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM”. If this
occurs making sure the rear fascia/bumper is free
from snow, ice, mud, dirt and debris, see your autho-
rized dealer.
•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. ParkSense might not detect an obstacle
behind the fascia/bumper, or it could provide a false
indication that an obstacle is behind the fascia/
bumper.

•Objects must not be within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the instrument cluster.
CAUTION!
•ParkSenseis only a parking aid and it is unable
to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected 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 Park-
Sense to be able to stop in time when the 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 the ParkSense Rear Park Assist Sys-
tem. Always check carefully behind your vehicle,
look behind you, and be sure to check for pedes-
trians, 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.

WARNING! (Continued)
•Before using the ParkSenseRear Park Assist
System, it is strongly recommended that the ball
mount and hitch ball assembly 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 warning display turns on the
single flashing arc and sounds the continuous
tone. Also, the ParkSense sensors could detect
the ball mount and hitch ball assembly, depending
on its size and shape, giving a false indication that
an obstacle is behind the vehicle.
PARKVIEW REAR BACK UP CAMERA — IF
EQUIPPED
Your vehicle may be equipped with the ParkView Rear
Back Up Camera that allows you to see an on-screen
image of the rear of your vehicle whenever the shift lever
is put into REVERSE. The image will be displayed on the
Navigation/Multimedia radio display screen. The Park-
View camera is located on the rear liftgate.
WARNING!
Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing up. You are
responsible for the safety of your surroundings and
must continue to pay attention while backing up.
Failure to do so can result in serious injury or death.
