WARNING
●
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow
speeds, there is a possibility that the obstacle will come within the sensor’ detec-
tion areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow
noise of the air conditioning system.
NOTICE
■
When using Lexus parking assist-sensor
In the following situations, the system may not function correctly due to a sensor mal-
function, etc. Have the vehicle checked by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
●
The Lexus parking assist-sensor operation display flashes, and a buzzer sounds when
no obstacles are detected.
●
If the area around a sensor collides with something, or is subjected to strong impact.
●
If the bumper collides with something.
●
If the display shows continuously without beeping, except when the buzzer mute
switch has been turned on.

sensor is malfunctioning.
