■Buzzer operation and distance to
an object
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously:
Approximately 1.0 ft. (30 cm)
When 2 or more objects are
detected simultaneously, the buzzer
sounds for the nearest object. If one
or more objects come within
approximately 1.0 ft. (30 cm) of the
vehicle, the buzzer will repeat a long
tone, followed by fast beeps.
 Automatic buzzer mute function:
After a buzzer begins sounding, if the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. (30 cm) or less,
this function will not operate.)
The buzzer sounds volume can be
adjusted. ( P.202)

forward to backing up, or from backing
up to moving forward)
■If “Parking Support Brake Unavailable”
is displayed on th e multi-information
display and the PKSB OFF indicator is
flashing
If this message is displayed only when the
shift lever is in any po sition other than R, a
sensor on the front or rear bumper may be
dirty. Clean the sensors and their surround-
ing area on the bumpers.
■If “Parking Support Brake Unavailable”
and “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-information display and the
PKSB OFF indicator is flashing
●A sensor may be cove red with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to
normal.
If this message is shown even after
removing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehicle inspected by your
Lexus dealer.
●A sensor may be frozen. Once the ice
melts, the system wi ll return to normal.
●Water may be continuo usly flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
