System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of dirt and debris
to keep ParkSense
௡ operating 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 DISABLED.” 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 instrument
cluster will display “PARK ASSIST DISABLED” mes-
sage for as long as the vehicle is in REVERSE.
• ParkSense௡, when on, will MUTE the radio when it is
sounding a tone.
• If a ParkSense௡ system malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM”. If this
occurs making sure the rear fascia/bumper is free
from snow, ice, mud, dirt and debris, see your autho-
rized dealer.
• 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. ParkSense
௡ might not detect an obstacle
behind the fascia/bumper, or it could provide a false
indication that an obstacle is behind the fascia/
bumper.
