Setting the buzzer volume
■
The buzzer volume can be adjusted on the
multi-information display. (P.135)
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.301)
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.
Sensor detection information
■
● The sensor's detection areas are limited
4-5. Using the driving support systems
to the areas around the vehicle's front and
rear bumpers.
● The following situations may occur
during use.
• 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.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
● A sensor is covered in any way.
On an extremely bumpy road, on an
●
incline, on gravel, or on grass.
● When a sensor or the area around a sen-
sor is extremely hot or cold.
The vicinity of the vehicle is noisy due to
●
vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
● There is another vehicle equipped with
parking assist sensors in the vicinity.
● A sensor is coated with a sheet of spray
or heavy rain.
