2011 JEEP GRAND CHEROKEE parking sensors

RCP monitors the rear detection zones on both sides of
the vehicle, for objects that are moving toward the side of
the vehicle with a minimum speed of approximately 1 to
2 mph (1 km/h to 3 km/h), to objects moving a maxi-
mum of approximately 10 mph (16 km/h), such as in
parking lot situations.NOTE:
In a parking lot situation, oncoming vehicles can
be obscured by vehicles parked on either side. If the
sensors are blocked by other structures or vehicles, the
system will not be able to alert the driver.
When RCP is on and the vehicle is in REVERSE, the
driver is alerted using both the visual and audible
alarms, including reducing the radio volume.
WARNING!
RCP is not a Back Up Aid system. It is intended to be
used to help a driver detect an oncoming vehicle in a
parking lot situation. Drivers must be careful when
backing up, even when using RCP. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before back-
ing up. Failure to do so can result in serious injury or
death.

PARKSENSEREAR PARK ASSIST —
IF EQUIPPED
The ParkSense Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense System
Usage Precautions for limitations of this system and
recommendations.
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. If ParkSense is enabled at this shift lever
position, the system will remain active until the vehicle
speed is increased to approximately 11 mph (18 km/h) or
above. The system will become 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/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 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 orienta-
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from the Customer- Pro-
grammable Features section of the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.

•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.
