Lexus parking assist-sensor display
■
Vehicles with a Lexus Display Audio system: When an obstacle is detected while the
●
Lexus parking assist monitor is in use, the warning indicator will appear in the upper
part of the screen even if the display setting has been set to off.
Vehicles with a navigation system: If the Lexus parking assist-sensor display is set to on,
●
detected objects will also be displayed on the panoramic view monitor. For details, refer
to "NAVIGATION SYSTEM OWNER'S MANUAL".
Sensor detection information
■
The sensor's detection areas are limited to the areas around the vehicle's bumper.
●
Certain vehicle conditions and the surrounding environment may affect the ability of a
●
sensor to correctly detect an obstacle. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.
