2012 JEEP GRAND CHEROKEE Owner handbook (in English)

The system will indicate a detected obstacle by
showing three solid arcs and will produce a
one-half second tone. As the vehicle moves
closer to the object the EVIC display will show
fewer arcs and the sound tone will change from
slow, to fast, to continuous.The vehicle is close to the obstacle when the
EVIC display shows one flashing arc and
sounds a continuous tone. The following chart
shows the warning alert operation when the
system is detecting an obstacle:

Enabling And Disabling ParkSense ParkSensecan be enabled and disabled with
a switch located in the switch bank of the
instrument panel or through the Customer-
Programmable Features section of the EVIC.
The available choices are: OFF, Sound Only, or

(Customer-Programmable Features)” in “Un-
derstanding Your Instrument Panel” for further
information.
When the ParkSense switch is
pressed to disable the system, the
instrument cluster will display the
“PARK ASSIST SYSTEM OFF”
message for approximately five
seconds. Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in- formation. When the shift lever is moved to
REVERSE or to DRIVE (at or below
11 mph/18 km/h) and the system is disabled,
the EVIC will display the “PARK ASSIST SYS-
TEM OFF” message for as long as the vehicle is
in REVERSE or for five seconds when the
vehicle is in DRIVE.
The ParkSense
switch LED will be ON when
ParkSense is disabled or defective. The Park-
Sense switch LED will be OFF when the
system is enabled.

Service The ParkSensePark Assist
System
When the ParkSense Park Assist System is
malfunctioning, the instrument cluster will actu-
ate a single chime, once per ignition cycle. The
instrument cluster will display the “CLEAN
PARK ASSIST SENSORS” message when any
of the rear or front sensor(s) is blocked by
snow, mud, or ice and the vehicle is shifted into
REVERSE or DRIVE.
The instrument cluster will display the “SER-
VICE PARK ASSIST SYSTEM” message when
any of the rear or front sensors are damaged
and require service. When the shift lever is
moved to REVERSE or DRIVE and the system
has detected a faulted condition, the EVIC will
display the “CLEAN PARK ASSIST SENSORS”
or the “SERVICE PARK ASSIST SYSTEM” mes-
sage for as long as the vehicle is in REVERSE
or DRIVE (at speeds less than
11 mph/18 km/h). Under this condition Park-
Sense will not operate. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in-
formation. If the “CLEAN PARK ASSIST SENSORS” mes-
sage appears in the Electronic Vehicle Informa-
tion Center (EVIC) make sure the rear fascia/
bumper and/or front 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 autho-
rized dealer.
Cleaning The ParkSense
SystemClean 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 sen-
sors. Otherwise, you could damage the sen-
sors.
ParkSense System Usage
Precautions
NOTE:
• Ensure that the front and rear bumper are
free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating
properly.
• Jackhammers, large trucks, and other vi-
brations could affect the performance of
ParkSense. •
When you turn ParkSense off, the instru-
ment cluster will display “PARK ASSIST
SYSTEM 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 or DRIVE position and Park-
Sense is turned off, the instrument clus-
ter will display “PARK ASSIST SYSTEM
OFF” message for as long as the vehicle
is in REVERSE and when the vehicle is in
DRIVE at or below 11 mph (18 km/h).
• ParkSense, when on, will MUTE 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 be-
hind or in front of the fascia/bumper, or it
could provide a false indication that an
obstacle is behind or in front of the fascia/
bumper.
135

•Objects such as bicycle carriers, trailer
hitches, etc., must not be placed 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, caus-
ing the “SERVICE PARK ASSIST SYS-
TEM” message to be displayed in the
instrument cluster.
• On vehicles equipped with a tailgate,
ParkSense should be disabled when the
tailgate is in the lowered or open position.
A lowered tailgate 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, includ-
ing small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sen-
sors will not be detected when they are in
close proximity.
(Continued)
CAUTION!(Continued)
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is detected.
When backing up, 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 Park
Assist System. Always check carefully be-
hind your vehicle, look behind you, and be
sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. You are respon-
sible 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 the ParkSense 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 ve-
hicles 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 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.
PARKVIEW REAR BACK UP
CAMERA — IF EQUIPPED
Your vehicle may be equipped with the Park-
View Rear Back Up Camera that allows you to
see an on-screen image of the rear surround-
ings of your vehicle whenever the shift lever is
put into REVERSE. The image will be displayed
136

on the Navigation/Multimedia radio display
screen along with a caution note to “check
entire surroundings” across the top of the
screen. After five seconds this note will disap-
pear. The ParkViewcamera is located on the
rear of the vehicle above the rear License plate. When the vehicle is shifted out of REVERSE, the
rear camera mode is exited and the navigation
or audio screen appears again.
When displayed, static grid lines will illustrate
the width of the vehicle while a dashed center-
line will indicate the center of the vehicle toassist with aligning to a hitch/receiver. The
static grid lines will show separate zones that
will help indicate the distance to the rear of the
vehicle. The following table shows the approxi-
mate distances for each zone:
Zone
Distance to the rear of the vehicle
Red 0-1ft(0-30cm)
Yellow 1 ft-3ft(30cm-1m)
Green 3 ft or greater (1 m or greater)
WARNING!
Drivers must be careful when backing up even
when using the ParkViewRear Back Up
Camera. Always check carefully behind your
vehicle, and be sure to check for pedestrians,
animals, other vehicles, obstructions, 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.CAUTION!
• To avoid vehicle damage, ParkView 
should only be used as a parking aid. The
ParkView camera is unable to view every
obstacle or object in your drive path.
• To avoid vehicle damage, the vehicle must
be driven slowly when using ParkView to
be able to stop in time when an obstacle is
seen. It is recommended that the driver
look frequently over his/her shoulder when
using ParkView. NOTE:
If snow, ice, mud, or any foreign substance
builds up on the camera lens, clean the lens,
rinse with water, and dry with a soft cloth. Do
not cover the lens.

•Never leave children in a vehicle with the
key in the ignition switch. Occupants, par-
ticularly unattended children, can become
entrapped by the power sunroof while op-
erating the power sunroof switch. Such
entrapment may result in serious injury or
death.
• In a collision, there is a greater risk of being
thrown from a vehicle with an open sunroof.
You could also be seriously injured or killed.
Always fasten your seat belt properly and
make sure all passengers are properly se-
cured too.
• Do not allow small children to operate the
sunroof. Never allow your fingers, other
body parts, or any object to project through
the sunroof opening. Injury may result.

Sunshade OperationThe sunshade can be opened manually. How-
ever, the sunshade will open automatically as
the sunroof opens.
NOTE:
The sunshade cannot be closed if the sun-
roof is open.
Wind BuffetingWind buffeting can be described as the per-
ception of pressure on the ears or a helicopter-
type sound in the ears. Your vehicle may exhibit
wind buffeting with the windows down, or the
sunroof (if equipped) is in certain open or
partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting
occurs with the rear windows open, open the
front and rear windows together to minimize the
buffeting. If the buffeting occurs with the sun-
roof open, adjust the sunroof opening to mini-
mize the buffeting or open any window.
Sunroof MaintenanceUse only a nonabrasive cleaner and a soft cloth
to clean the glass panel.
Ignition OFF OperationThe power sunroof switches remain active for
up to approximately ten minutes after the igni-
tion switch has been turned OFF. Opening
either front door will cancel this feature. The
time is programmable. Refer to “Electronic Ve-
hicle Information Center (EVIC)/Personal Set-tings (Customer-Programmable Features)” in
