Sensor detection information

The sensor's detection areas are limited to the areas around the vehicle'
●
bumper.
Certain vehicle's 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 ice, snow or mud on a sensor.
• A sensor is frozen. If the sensor is deiced, the Toyota parking assist-sen-
sor will work properly.
• A sensor is covered with something.
• On a 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 ultra
sonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• A sensor is splashed with water or heavy rain.
• A fender pole, radio antenna or fog light is installed.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• An obstacle is directly under the bumper.
• If obstacles is too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• An illuminated type license plate is installed.
• A backlit license plate, license plate holder, etc., are installed.
• The tilt angle of the vehicle is considerably increased.
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.
