Cleaning The ParkSense System
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 damage the
sensors.
ParkSense System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow, ice, mud, dirtand debris to keep the ParkSense system operating prop -
erly.
• Jackhammers, large trucks, and other vibrations could affect the performance of ParkSense.
• When you move the gear selector into REVERSE with ParkSense turned off, the instrument cluster display will
show "Off" on the vehicle graphic arcs for as long as the
vehicle is in REVERSE.
• ParkSense, when on, will reduce the volume of 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 Park -
Sense 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.
• Ensure the ParkSense system is OFF if objects such as bicycle carriers, trailer hitches, etc., are placed within
18 inches (45 cm) of the rear fascia/bumper while driving
the vehicle. Failure to do so can result in the system misin -
terpreting a close obstacle as a sensor problem, causing the
"Rear ParkSense Unavailable Service Required" message
to appear in the instrument cluster display.
WARNING!
• Drivers must be careful when backing up even when using ParkSense. Always check carefully behind your
vehicle, look behind you, and be sure to check for
pedestrians, 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.

324 STARTING AND OPERATING
Service The ParkSense Front/Rear Park Assist
System
During vehicle start up, when the Front/Rear ParkSense
System has detected a faulted condition, the instrument
cluster display will show the "Front/Rear ParkSense
Unavailable Service Required" or the "Front/Rear ParkSense
Unavailable Wipe Sensors" message.
When the gear selector is moved into REVERSE, a vehicle
graphic will show in the instrument cluster display, along
with the display overlay “Front/Rear ParkSense Unavail-
able Wipe Sensors.” If the system needs service, the display
overlay will read “Front/Rear ParkSense Unavailable
Service Required.” Under this condition, ParkSense will not
operate.
If "Front/Rear ParkSense Unavailable Wipe Sensors"
appears in the instrument cluster display make sure the
outer surface and the underside of the rear 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 "Front/Rear ParkSense Unavailable Service Required"
appears in the instrument cluster display, see an authorized
dealer.

(Continued)
• Clean the ParkSense sensors regularly, taking care not toscratch 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 Park -
Sense system might not detect an obstacle behind or in
front of the fascia/bumper, or it could provide a false indi -
cation that an obstacle is behind or in front of the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system off if obstacles such as bicycle carriers, trailer hitches, etc. are
placed within 18 inches (45 cm) from the rear fascia/
bumper. Failure to do so can result in the system misinter -
preting a close obstacle as a sensor problem, causing the
“Front/Rear ParkSense Unavailable Service Required”
message to be appear in the instrument cluster display.
WARNING!
• Drivers must be careful when backing up even when using ParkSense. Always check carefully behind your
vehicle, look behind you, and be sure to check for
pedestrians, 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.
• Before using ParkSense, it is strongly recommendedthat the ball mount and hitch ball assembly is discon -
nected 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 loudspeaker 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.
CAUTION!
• ParkSense is only a parking aid and it is unable to recognize every obstacle, including 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 Park -
Sense 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.

SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call system
capabilities.
SOS or other emergency line operators in Mexico may not
answer or respond to SOS system calls.
If the SOS Call system detects a malfunction, any of the
following may occur at the time the malfunction is detected,
and at the beginning of each ignition cycle:
• The overhead console light located between the ASSIST and SOS buttons will continuously be illuminated red.
• The Device Screen will display the following message: “Vehicle device requires service. Please contact your
dealer.”
• An In-Vehicle Audio message will state “Vehicle device requires service. Please contact your dealer.”
• Never place anything on or near the vehicle’s operable
network and GPS antennas. You could prevent oper -
able network and GPS signal reception, which can
prevent your vehicle from placing an emergency call.
An operable network and GPS signal reception is
required for the SOS Call system to function properly.
• The SOS Call system is embedded into the vehicle’s electrical system. Do not add aftermarket electrical
equipment to the vehicle’s electrical system. This may
prevent your vehicle from sending a signal to initiate
an emergency call. To avoid interference that can cause
the SOS Call system to fail, never add aftermarket
equipment (e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical system or
modify the antennas on your vehicle. IF YOUR
VEHICLE LOSES BATTERY POWER FOR ANY
REASON (INCLUDING DURING OR AFTER AN
ACCIDENT), THE UCONNECT FEATURES, APPS
AND SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
WARNING! (Continued)
• Modifications to any part of the SOS Call system could
cause the air bag system to fail when you need it. You
could be injured if the air bag system is not there to
help protect you.
