While audible signals are emitted, the audio system is not
muted.
The audible signal is turned off immediately if the
distance increases. The tone cycle remains constant if the
distance measured by the inner sensors is constant. If this
condition occurs for the external sensors, the signal is
turned off after three seconds (stopping warnings during
maneuvers parallel to walls).
ParkSense® Rear Park Assist Failure Indications
A malfunction of the ParkSense® Rear Park Assist sen-
sors or system is indicated, during REVERSE gear en-
gagement, by the instrument panel warning icon.
The warning icon is illuminated and a message
is displayed on the multifunction display (if
equipped). Refer to “Instrument Cluster De-
scriptions” in “Understanding Your Instrument
Panel” for further information.
The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indi-
cated immediately if they occur when the system is ON.
Even if the system is able to identify that a specific sensor
is in failure condition, the instrument cluster display
shall indicate that the ParkSense® Rear Park Assist
system is unavailable, without reference to the sensor in
failure condition. If even a single sensor fails, the entire
system must be disabled. The system is turned off
automatically.
Cleaning The ParkSense® Rear Park Assist
System
Clean the ParkSense® Rear Park Assist sensors with
water, car wash soap and a soft cloth. Do not use rough
or hard cloths. In washing stations, clean sensors quickly
keeping the vapor jet/high pressure washing nozzles at
least 4 in (10 cm) from the sensors. Do not scratch or poke
the sensors. Otherwise, you could damage the sensors.
