Limitations of the sensors
●The detection areas of the sensors are limited to the areas aro und the vehi-
cle’s front corners and the rear bumpers.
● Certain vehicle conditions and surrounding environments, such a s the fol-
lowing, may affect the ability of the sensors to correctly dete ct objects. Pay
particular attention in the following situations. Failure to do so may result in
the vehicle being driven unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a sensor (Cleaning the sens or will
resolve this problem.)
• When the sensor is frozen (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or objects may not be detected
• When a sensor is covered in any way
• When the vehicle is leaning considerably to one side
• When driving on an extremely bumpy road, incline, gravel, or g rass
• When the vicinity of the vehicle is noisy due to vehicle horns , motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves
• When there is another vehicle equipped with parking assist sen sor in the
vicinity
• When the sensor is coated with a sheet of spray or heavy rain
• When the vehicle is equipped with a fender pole or wireless an tenna
• When a towing eyelet is installed
• When a bumper or sensor receives a strong impact
• A backlit license plate, license plate holder, etc., are insta lled.
• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlight or intense cold weather
• When an object is directly under a bumper
• When objects become too close to the sensors
• When a non-genuine Toyota suspension (lowered suspension, etc. ) is
installed
In addition to the situations above, there are instances in which, because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.
