ParkSense® System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense® system oper-
ating 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 SYSTEM OFF.” Further-
more, 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 EVIC will
display “PARK ASSIST SYSTEM 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 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 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 EVIC .
