• When you turn off the Rear Park Assist System, the
instrument cluster will display “PARK ASSIST DIS-
ABLED.” Furthermore, once you turn off the Rear
Park Assist System, 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 the Rear Park Assist System is turned off,
the instrument cluster will display “PARK ASSIST
DISABLED” message for as long as the vehicle is in
REVERSE.
• The Rear Park Assist System, when on, will MUTE the
radio when it is sounding a tone.
• If a Rear Park Assist 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 SYS-
TEM”. If this occurs making sure the rear fascia/
bumper is free from snow, ice, mud, dirt and debris,
see your authorized dealer.
• Clean the Rear Park Assist 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 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 must not be 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.
