4-5. Using the driving support systems
■
The Lexus parking assist-sensor can be
operated when
●
Front corner sensors:
• The engine switch is in IGNITION ON
mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than about 10
km/h (6 mph).
(At any speed when the shift lever is in R)
●
Rear corner and rear center sensors:
• The engine switch is in IGNITION ON
mode.
• The shift lever is in R.
■
Muting the buzzer sound
●
To mute the buzzer sound:
The buzzer can be temporarily muted by
pressing “OK” of the meter control
switches while an obstacle detection dis-
play is shown on the multi-information dis-
play.
●
To cancel the mute:
Mute will be automatically canceled in the
following situations.
• When the shift lever is changed (except
shifting from D to N, or N to D).
• When the vehicle speed has reached or
exceeded 10 km/h (6 mph) with the shift
lever in D.
• When the Lexus parking assist-sensor is
turned off once and turned on again.
• When the engine switch is turned off
once and turned to IGNITION ON
mode again.
■
If “Clean Parking Assist Sensor” is dis-
played 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 dur-
ing 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.)
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.
●
When a sensor or the area around a sen-
sor is extremely hot or cold.
●
On an extremely bumpy road, on an
incline, on gravel, or on grass.
●
The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
●
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.
