■
If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■
If “Parking Assist Unavailable” is dis-
played on the multi-information display
●
Water may be continuously 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.
●
Initialization may not have been per-
formed after a 12-volt battery terminal
was disconnected and reconnected. Ini-
tialize the system. (

P.348)
If this message continues to be displayed
even after initialization, have the vehicle
inspected by your Lexus dealer.
■
If a 12-volt battery terminal has been
disconnected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 35 km/h (22 mph) or more.
Additionally, for vehicles with the Parking
Support Brake function, turn the steering
wheel fully to the left and right with the vehi-
cle stopped.
WARNING

■
When using Lexus parking assist-sen-
sor
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●
The Lexus parking assist-sensor oper-
ation display flashes or shows continu-
ously, and a beep sounds when no
objects are detected.
●
If the area around a sensor collides
with something, or is subjected to
strong impact.
●
If the bumper or grille collides with
something.
●
If the display flashes or is displayed
continuously and a buzzer does not
sound, except when the mute function
has been turned on.
●
If a display error occurs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■
Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.
●
When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●
When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.
