4-5. Using the driving support systems
■The system can be operated when
●The engine switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●Steering wheel is turned approxi-mately 90° or more (Front side sen-sors, rear side sensors) (if equipped)
●The parking brake is released.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to normal.
■Sensor detection information
The following situations may occur during use.
●The sensors may be able to only detect objects near the front and rear bumpers.
●Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
●If an object is extremely close to a sensor, it may not be detected.
●There will be a short delay between object detection and display. Even at low speeds, there is a possibility that
the object will come within the sen- sor’s detection areas before the dis-play is shown and the warning beep
sounds.
●It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
●It may be difficult to hear the buzzer if buzzers for other systems are sound-
ing.
■Objects which the system may not be properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
WARNING
●Do not modify, disassemble or paint the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the function as it may operate even though there is no possibility of a colli-
sion.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
●When using a high pressure washer to wash the vehicle, do not spray the sensors directly, as doing
so may cause a sensor to malfunc- tion.
●When using steam to clean the vehicle, do not direct steam too close to the sensors as doing so
may cause a sensor to malfunction.
