Driving

■

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 

mph (10 km/h).

●

A shift lever other than P.

■

Setting the buzzer volume

The buzzer volume can be adjusted on the 

multi-information display. (



P.202)

■

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 battery terminal was dis-

connected and reconnected. Initialize the 

system. (



P.205)

If this message continues to be displayed 

even after initialization, have the vehicle 

inspected by your Lexus dealer.

■

If a battery terminal has been discon-

nected 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 22 mph (35 km/h) or more.

■

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.

• 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.

■

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.

WARNING

■

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.

●

Failing to observe the warnings above.

●

A non-genuine Toyota 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.
