4-5. Using the driving support systems
■ The system can be operated when
● The engine switch is in IGNITION ON
mode.
● Intuitive parking assist function is on.
● The vehicle speed is less than about 6
mph (10 km/h).
● A shift lever other than P.
■ Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. (P.209)
■ 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 battery terminal was dis-
connected and reconnected. Initialize the
system. (P.212)
If this message continues to be displayed
even after initialization, have the vehicle
inspected by your Lexus dealer.
■ If a battery terminal has been discon-
nected 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 22 mph (35 km/h) or more.
■ Sensor detection information
● The sensor's detection areas are limited
to the areas around the vehicle front and
rear bumpers.
● The following situations may occur
during use.
• Depending on the shape of the object
● Towing eyelets are installed.
● A backlit licence plate is installed.
■ When using intuitive parking assist
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 intuitive parking assist operation
display flashes or shows continuously,
and a buzzer 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.
