●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.
NOTICE
●When using intuitive parking assist-sen-
sor
In the following situations, the system may
not function correctly due to a sensor
malfunction etc. Have the vehicle
checked by your Lexus dealer.
• The intuitive parking assist operation display flashes, 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 collides with something.
• If the display shows continuously with- out a beep (except when mute is turned
on).
• If a display error occurs, first check the sensor.
If the error occurs even if 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.
