4-5. Using the driving support systems
■The intuitive parking assist can be operated when
●The engine switch is in the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system).
● Front corner sensors:
• The shift lever is not in P.
• The vehicle speed is approximately 6 mph (10 km/h) or less.
● Rear corner and rear center sensors:
The shift lever is in R.
■ Intuitive parking assist display
When an obstacle is detected while the rear view monitor system is in use,
the warning indicator will appear in the upper corner of the screen even if the
display setting has been set to off.
■ 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 the sensor to correctly detect obstacles. 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
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• 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 Toyota 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 shapes, signs and other objects may be judged by the sensor to be
closer than they are.
