WARNING

■

When using the intuitive parking

assist

Observe the following precautions.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

●

Do not use the sensor at speeds in

excess of 6 mph (10 km/h).

●

The sensors’ detection areas and reac-

tion times are limited. When moving

forward or reversing, check the areas

surrounding the vehicle (especially the

sides of the vehicle) for safety, and

drive slowly, using the brake to control

the vehicle’s speed.

●

Do not install accessories within the

sensors’ detection areas.

●

The area directly under the bumpers is

not detected.

■

When to disable the function

In the following situations, disable the

function as it may operate even though

there is no possibility of a collision.

●

The vehicle is equipped with a fender

pole, wireless antenna or fog lights.

●

The front or rear bumper or a sensor

receives a strong impact.

●

A non-genuine Lexus suspension

(lowered suspension, etc.) is installed.

●

Towing eyelets are installed.

●

A backlit licence plate is installed.

●

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 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.)

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.

260

4-5. Using the driving support systems

LS500_OM_(U)_1809

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

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.

●

If a sensor is hit by a large amount of

water, such as when driving on a flooded

road.

●

If the vehicle is significantly tilted.

●

The vehicle is approaching a tall or

curved curb.

●

If objects draw too close to the sensor.

■

Objects which 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-

 The buzzer beeps faster as the vehi-

cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously:

Approximately 1.0 ft. (30 cm)

 When 2 or more objects are

detected simultaneously, the buzzer
sounds for the nearest object. If one
or more objects come within
approximately 1.0 ft. (30 cm) of the
vehicle, the buzzer will repeat a long
tone, followed by fast beeps.

 Automatic buzzer mute function:

After a buzzer begins sounding, if
the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. (30 cm) or less,
this function will not operate.)
