■The windshield wiper and washer can be operated when
The engine switch is in ON.
■Effects of vehicle speed on wiper operation (vehicles with rain-sens-ing windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●The raindrop sensor judges the amount of raindrops.
An optical sensor is adopted. It may
not operate properly when sunlight from the rising or setting of the sun intermittently strikes the windshield, or
if bugs etc. are present on the wind- shield.
●If the wiper is turned to AUTO mode while the engine switch is in ON, the wipers will operate once to show that
AUTO mode is activated.
●If the temperature of the raindrop sen-
sor is 85°C (185°F) or higher, or -15°C (5°F) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield washer fluid reservoir.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode (vehicles with rain-sensing wind-
shield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched
or the windshield is subject to vibra- tion in AUTO mode. Take care that your fingers or anything else do not
become caught in the windshield wip- ers.

WARNING
■When using the Toyota parking
assist-sensor
Observe the following precautions. Failing to do so may result in the vehi-
cle being unable to be driven safely and possibly cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or reversing, check
the areas surrounding the vehicle (especially the sides of the vehicle) for safety, and drive slowly, using
the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.
●The area directly under the bum-pers is not detected.Thin posts or objects lower than the
sensor may not be detected when approached, even if they have been detected before.
■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.
●The vehicle is equipped with a fender pole, wireless antenna or fog
lights.

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).
●A shift lever other than P is selected.
●Steering wheel is turned approxi- mately 90° or more (Front side sen-
sors, rear side sensors) (if equipped)
■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.
WARNING
●The front or rear bumper or a sen- sor receives a strong impact.
●A non-genuine Toyota suspension (lowered suspension, etc.) is
installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
■When using Toyota parking assist-sensor
In the following situations, the system
may not function correctly due to a sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●The Toyota parking assist-sensor operation display flashes or shows continuously, and a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display flashes or is displayed continuously and a buzzer does not sound, except when the mute func-
tion has been turned on.
●If a display error occurs, first check
the sensor. If the error occurs even when there is no ice, snow or mud on the sen-
sor, it is likely that the sensor is mal- functioning.
■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.
