• When you turn ParkSense® off, the instrument cluster
will display "PARKSENSE OFF." Furthermore, 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 "PARKSENSE OFF" 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 ParkSense® system might not detect an
obstacle behind 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.
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 231
• Use the ParkSense® switch to turn the ParkSense®
system off if objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 in (30 cm) from the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a sensor
problem, causing the "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" 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.
