WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or objects 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, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing 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 objects 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.
