■Steering control function
Depending on the vehicle speed, lane depart ure situation, road conditions, etc., the
driver may not feel the function is operat ing or the function may not operate at all.
■Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio playback, etc.
Also, it may be difficult to feel steering wheel vibrations due to the road conditions, etc.

■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obstacle, the
buzzer sounds continuously:
• Front center sensors: Appr oximately 30 cm (1.0 ft.)
• Corner sensors: Approximately 30 cm (1.0 ft.)
• Rear center sensors: Approximately 35 cm (1.1 ft.)
●When 2 or more obstacles are detect ed simultaneously, the buzzer system
responds to the nearest obstacle. If on e or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection range
of the sensors. Note that the sensors
cannot detect obstacles that are extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object etc.

Failing to do so may result in the vehicle be ing unable to be driven safely and possibly
cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or

WARNING
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor. • There will be a short delay between obstac le detection and display. Even at slow
speeds, there is a possibility that the ob stacle will come within the sensor’ detec-
tion areas before the display is shown and the buzzer sounds. • Thin posts or objects lower than th e 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.
