■When using the Lexus parking assist- sensor
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 10 km/h (6 mph).
●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.
NOTICE
■When using Lexus parking assist-sen-sor
In the following situations, the system may not function correctly due to a sen-
sor malfunction etc. Have the vehicle checked by any authorized Lexus retailer or Lexus authorized repairer, or any reli-
able repairer.
●The Lexus parking assist-sensor oper- ation display flashes or shows continu-
ously, and a beep sounds when no obstacles 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 shows continu-ously without beeping, 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.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching rap-idly from behind into a blind spot. Do not
overly rely on the BSM function. As the function cannot judge if it is safe to change lanes, over reliance could lead to
an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.
