6-2. Using the safe driving support functions
WARNING
A non-genuine Lexus suspension
●
(lowered suspension, etc.) is installed.
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 power switch is ON.
Intuitive parking assist function is on.
●
●
The vehicle speed is less than about 6
mph (10 km/h).
●
A shift position other than P is selected.
If "Parking Assist Unavailable Sensor
■
Blocked" is displayed on the multi-infor-
mation display
A sensor may be covered with water drops,
ice, snow, dirt, etc.
Remove the water drops, ice, snow, dirt,
etc., from the sensor to return the system to
normal.
If a sensor is dirty, the position of the dirty
sensor will be shown on the display.
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 a warning message is displayed even if the
sensor is clean, there may be a sensor mal-
function. Have the vehicle inspected by
your Lexus dealer.
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
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Detection may be impossible if static
objects draw too close to the sensor.
• There will be a short delay between static
object detection and display (warning
buzzer sounds). Even at low speeds,
there is a possibility that the object will
come within 1.0 ft. (30 cm) before the
display is shown and the warning buzzer
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 sound of this
system due to the buzzers of other sys-
tems.
■
Objects which the system may not be
properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
Wires, fences, ropes, etc.
●
●
Cotton, snow and other materials that
absorb sound waves
Sharply-angled objects
●
Low objects
●
●
Tall objects with upper sections project-
ing outwards in the direction of your vehi-
cle
People may not be detected if they are
wearing certain types of clothing.
■
Situations in which the system may not
operate properly
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, water drops or ice on
a sensor. (Cleaning the sensors will
