2010 JEEP GRAND CHEROKEE sensor

ParkSenseSensorsThe 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 ap-
proximately 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
orientation 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 orientation of the obstacle.ParkSense Warning DisplayThe ParkSense Warning screen will only be
displayed if Sound and Display is selected from
the Customer- Programmable Features section
of the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Information
Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding
Your Instrument Panel” for further information.
The ParkSense Warning Display is located in
the Instrument cluster’s EVIC display. It pro-
vides both visual and audible warnings to indi-
cate the distance between the rear fascia/
bumper and/or front fascia/bumper and the
detected obstacle.ParkSense DisplayThe warning display will turn ON indicating the
system status when the vehicle is in REVERSE

derstanding Your Instrument Panel” for further
information.
When the Park Sense switch is
pressed to disable the system, the
instrument cluster will display the
“PARK ASSIST OFF” message for
approximately five seconds. Refer
to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instru-
ment Panel” for further information. 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 AS-
SIST 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.
The ParkSense system uses four sensors lo-
cated in the rear bumper fascia to scan for
obstacles up to 79 in (200 cm) away from the
rear bumper fascia. The ParkSense system
135

uses six sensors located in the front bumper
fascia to scan for obstacles up to 47 in
(120 cm) away from the front bumper fascia.
The warning display located above in the In-
strument Cluster’s EVIC provides both visible
and audible warnings to indicate the range of
the object.
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 “REAR SEN-
SOR BLINDED” message when any of the rear
sensor(s) is blocked by snow, mud, or ice and
the vehicle is shifted into REVERSE or DRIVE.
The instrument cluster will display the “CLEAN
PARK ASSIST SENSORS” message when any
of the 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
“SERVICE 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” message 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) and the rear fascia/bumper
or front fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction, see
your authorized dealer. If “SERVICE PARK AS-
SIST SYSTEM” appears in the EVIC, see your
authorized 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
OFF.” Furthermore, once you turn Park-
Sense 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 OFF” mes-
sage 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.
136

•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.
• 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.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.
• 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.

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
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 ParkView camera 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 to
assist 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 f t-3ft(30cm-1m)
Green 3 ft or greater (1 m or greater)

11. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if
provided), should be checked
monthly, when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle, to ensure that thereplacement or alternate tires and wheels allow
the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may re-
sult when using replacement equipment that
is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor dam-
age. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with
a TPMS, as damage to the sensors may
result.
12. Position Light Indicator — If Equipped This indicator will illuminate when
the park lights or headlights are
turned on.
