System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of dirt and debris
to keep the Rear Park Assist System operating prop-
erly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of the Rear Park Assist System.
• 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,
a single chime will sound once per ignition cycle and
the instrument cluster will display “PARK ASSIST
DISABLED.”
• 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” and the LED in the Rear Park Assist switch will
illuminate. If this occurs, see your authorized dealer
for service.
CAUTION!
• The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
