consistently in some
stances depending on the speed of
the vehicle and the shapes of the
objects detected.

(Reverse) system may malfunction
if the vehicle bumper height or sen-
sor installation has been modified
or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor
performance.

snow, dirt, debris, or ice, the rear
parking assist system may be inop-
erative until the snow or ice melts,
or the debris is removed. Use a
soft cloth to wipe debris away from
the sensor.
