2013 JEEP GRAND CHEROKEE sensor

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
limitations of this system and recommenda-
tions.
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. The system will become
active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
ParkSense® SensorsThe 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 approxi-
mately 12 in (30 cm) up to 59 in (150 cm) from
the rear fascia/bumper in the horizontal direc-
tion, depending on the location, type and orien-
tation 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.

Service The ParkSense® Park Assist
System
When the ParkSense Park Assist System is
malfunctioning, the instrument cluster will actu-
ate a single chime, once per ignition cycle, and
it will display the “CLEAN PARK ASSIST SEN-
SORS” or the “SERVICE PARK ASSIST SYS-
TEM” message. The instrument cluster will dis-
play the “CLEAN PARK ASSIST SENSORS”
message when any of the rear or front sensors
are blocked by snow, mud, or ice. The instru-
ment 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 appro-
priately five seconds. Then, when the shift lever
is moved to REVERSE, the EVIC will display
the “PARK ASSIST SYSTEM OFF” message foras long as the vehicle is in REVERSE. Under
this condition ParkSense will not operate. Refer
to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.
If the “CLEAN PARK ASSIST SENSORS” mes-
sage appears in the Electronic Vehicle Informa-
tion Center (EVIC) make sure the outer surface
and the underside of 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 authorized dealer.
If the “SERVICE PARK ASSIST SYSTEM” mes-
sage appears in the EVIC, see an 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 sensors.
Otherwise, you could damage the sensors.
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 in-
strument cluster will display “PARK AS-
SIST 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 position and ParkSense is
turned off, the instrument cluster will dis-
play “PARK ASSIST SYSTEM OFF” mes-
sage for as long as the vehicle is in
REVERSE.

•ParkSense®, when on, will MUTE the ra-
dio 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.
•
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, causing
the “SERVICE PARK ASSIST SYSTEM”
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
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.
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.
• 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

Center”.
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 the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the origi-
nal equipment tires and wheels. TPMS pres-
sures and warning have been established for
the tire size equipped on your vehicle. Un-
desirable system operation or sensor dam-
age may result when using replacement
equipment that is not of the same size, type,
and/or style. Aftermarket wheels can cause
sensor damage. 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.

•Unstored Messages Until RUN
These messages deal primarily with the Re-
mote Start feature. This message type is dis-
played until the ignition is in the RUN state.
Examples of this message type are "Remote
Start Aborted - Door Ajar" and"Press Brake
Pedal and Push Button to Start".
• Five Second Unstored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. Examples of this message
type are "Memory System Unavailable - Not in
Park" and"Automatic High Beams On".
The Reconfigurable Telltales section is divided
into the white telltales area on the right, amber
telltales in the middle, and red telltales on the left.

Compass / Temperature DisplayThe compass readings indicate the direction the
vehicle is facing. The EVIC will display one of
eight compass readings and the outside tem-
perature.
NOTE:
The system will display the last known out-
side temperature when starting the vehicle
and may need to be driven several minutes
before the updated temperature is dis-
played. Engine temperature can also affect
the displayed temperature; therefore, tem-
perature readings are not updated when the
vehicle is not moving.Automatic Compass Calibration
This compass is self-calibrating, which elimi-
nates the need to manually reset the compass.
When the vehicle is new, the compass may
appear erratic and the EVIC will display CAL
until the compass is calibrated. You may also
calibrate the compass by completing one or
more 360–degree turns (in an area free from
large metal or metallic objects) until the CAL
indicator displayed in the EVIC turns off. The
compass will now function normally.
NOTE:
A good calibration requires a level surface
and an environment free from large metallic
objects such as buildings, bridges, under-
ground cables, railroad tracks, etc.Compass Variance
Compass Variance is the difference between
Magnetic North and Geographic North. To com-
pensate for the differences the variance should
be set for the zone where the vehicle is driven,
per the zone map. Once properly set, the com-
pass will automatically compensate for the dif-
ferences, and provide the most accurate com-
pass heading. For the most accurate compass
performance, the compass must be set using
the following steps.
NOTE:
Keep magnetic materials away from the top
of the instrument panel, such as iPod’s,
Mobile Phones, Laptops and Radar Detec-
tors. This is where the compass module is
located, and it can cause interference with
the compass sensor, and it may give false
readings.

Forward Collision Warning — If EquippedThe Forward Collision Warning (FCW) feature
can be can be set to Far, set to Near or turned Off.
The default status of FCW is the Far setting. This
means the system will warn you of a possible
collision with the vehicle in front of you when you
are farther away. This gives you the most reaction
time. To change the setting for more dynamic
driving select the Near setting. This warns you of
a possible collision with the vehicle in front of you
when you are much closer. This allows for a more
dynamic driving experience. To change FCW sta-
tus press and release the SELECT button until a
check-mark appears next to the feature showing
the system has been activated or the check-mark
is removed showing the system has been deacti-
vated.
For further information, refer to ”Adaptive
Cruise Control (ACC)” in “Understanding The
Features Of Your Vehicle.”Park Assist System — If Equipped
The Rear Park Assist system will scan for
objects behind the vehicle when the transmis-
sion is in the REVERSE position and the vehicle
speed is less than 11 mph (18 km/h). The
system can be enabled with Sound Only or
Sound and Display. To make your selection,
scroll up or down until the preferred setting is
highlighted, then press and release the SE-
LECT button until a check-mark appears next to
the setting, showing that the setting has been
selected. Refer to “Rear Park Assist System” in
“Understanding The Features Of Your Vehicle”
for system function and operating information.
Blind Spot Alert — If Equipped
There are three selections when operating Blind
Spot Alert. By pressing and releasing the SE-
LECT button once, the Blind Spot Alert feature
can be activated in “Blind Spot: Lights Only”
mode. When this mode is selected the Blind
Spot Monitor (BSM) system is activated and will
only show a visual alert in the outside mirrors.
By pressing and releasing the SELECT button a
second time “Blind Spot: Lights/CHM” mode is
activated. In this mode the Blind Spot Monitor(BSM) will show a visual alert in the outside
mirrors as well as an audible alert when the turn
signal is on. When “Blind Spot: Off” is selected
the Blind Spot Monitor (BSM) system is deacti-
vated.
NOTE:
If your vehicle has experienced any damage
in the area where the sensor is located, even
if the fascia is not damaged, the sensor may
have become misaligned. Take your vehicle
to an authorized dealer to verify sensor
alignment. Having a sensor that is mis-
aligned will result in the BSM not operating
to specification.
