Sensors
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 problem.)
●
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 ultra-
sonic waves.
●
There is another vehicle equipped with parking assist sensors in the vicin-
ity.
●
The sensor is coated with a sheet of spray or heavy rain.
●
The sensor is drenched with water on a flooded road.
●
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.
●
The detection range is reduced due to an object such as a sign.
●
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 Toyota suspension (lowered suspension, etc.) is installed.
●
A backlit license plate is installed.
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.
