2011 JEEP GRAND CHEROKEE sensor

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. Under this condition, ParkSense
will not operate.
If “CLEAN PARK ASSIST SENSORS” appears in the
Electronic Vehicle Information Center (EVIC) and the
rear fascia/bumper is clean and clear of snow, ice, mud,
dirt or other obstruction, see your authorized dealer.
If “SERVICE PARK ASSIST SYSTEM” appears in the
EVIC, see your authorized dealer.
Cleaning The ParkSenseSystem
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 operat-
ing 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 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 display “PARK ASSIST OFF” message for
as long as the vehicle is in REVERSE.
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.

•Clean the ParkSensesensors 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.
•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 and the vehicle is in REVERSE. 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, 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
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 the ParkSenseRear 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 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.

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
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem 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 theTPMS 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 original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement 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.

5. Complete one or more 360–degree turns (in an area
free from large metal or metallic objects) until the “CAL”
indicator turns off. The compass will now function
normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences, and provide the most accurate compass
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 Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings. 1. Turn the ignition switch ON.
2. Press the UP or DOWN button until the Setup
(Customer-Programmable Features) menu is reached,
then press the SELECT button.

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 misaligned will result
in the BSM not operating to specification.
Forward Collision Warning
The 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 status press
and release the SELECT button until a check-mark ap-
pears next to the feature showing the system has been
activated or the check-mark is removed, showing the
system has been deactivated.
For further information, refer to ”Adaptive Cruise Con-
trol (ACC)” in “Understanding The Features Of Your
Vehicle”.
Display Units of Measure In:
The EVIC, odometer, and Uconnect™ gps (if equipped)
