• 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
