WARNING
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.
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

4-5. Using the driving support systems
mph (10 km/h).
● A shift position other than P is selected.
■ Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. (P.256)
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.
■ Sensor detection information
The following situations may occur
●
during use.
• The sensors may be able to only detect
objects near the front and rear bumpers.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor's
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if
buzzers for other systems are sounding.
■ Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
There is dirt, snow or ice on a sensor.
●
(Cleaning the sensors will resolve this
problem.)
A sensor is frozen. (Thawing the area will
●
resolve this problem.)
