WARNING
■ Sensor detection information
Pay particular attention to the following instances in where this may occur.
Failing to do so way result in the vehicle being unable to be driven or parked safety and possibly cause an accident.
● The sensor’s detection areas are limited to the areas around the vehicle’s rear 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.)
• 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 ultrasonic 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 radio 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.
• A backlit license plate, license plate holder, etc., are installed.
• People may not be detected if they are wearing certain types and coloring of clothing.
• People, animals, and moving objects may not be able to be detected.
In addition to the examples above, there are instances in which, because of their shape, signs and other objects may be judged by the sensor to be closer than they are.

WARNING
● The shape of the obstacle may prevent the sensor from detecting it. Pay particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehicle
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display.
Even at slow speeds, there is a possibility that the obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the sensor may not be detected for collision when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.
NOTICE
■ When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.
● A beep does not sound when you turn the main switch on.
● The intuitive parking assist operation display flashes, and a beep sounds when no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to strong impact.
● If the bumper collides with something.
● If the display shows continuously without a beep.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning.
■ 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.

Rear view monitor system precautions
■ Area displayed on screen
The rear view monitor system displays an image of the view from the bumper of the rear area of the vehicle.
■
The image adjustment procedure for the rear view monitor system screen is the same as the procedure for adjusting the multimedia screen.( →
• The area displayed on the screen may vary according to vehicle orientation conditions.
• Objects which are close to either corner of the bumper or under the bumper cannot be seen on the screen.
• The camera uses a special lens.
Corners of bumper
The distance of the image that appears on the screen differs from the actual distance.
• Items which are located higher than the camera may not be displayed by the monitor.
Rear view monitor system camera
The camera for the rear view monitor system is located as shown in the illustration.

● Using the camera
If dirt or foreign matter (such as water droplets, snow, mud, etc.) is adhering to the camera, it cannot transmit a clear image. In this case, flush it with a large quantity of water and wipe the camera lens clean with a soft and wet cloth.

■ Differences between the screen and the actual road
The distance guide lines and the vehicle width guide lines may not actually be parallel with the dividing lines of the parking space, even when they appear to be so. Be sure to check visually.
The distances between the vehicle width guide lines and the left and right dividing lines of the parking space may not be equal, even when they appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road surfaces. In any of the following situations, there is a margin of error between the fixed guide lines on the screen and the actual distance/course on the road.
● When the ground behind the vehicle slopes up sharply
The distance guide lines will appear to be closer to the vehicle than the actual distance.
Because of this, objects will appear to be farther away than they actually are. In the same way, there will be a margin of error between the guide lines and the actual distance/course on the road.

● When the ground behind the vehicle slopes down sharply
The distance guide lines will appear to be farther from the vehicle than the actual distance. Because of this, objects will appear to be closer than they actually are. In the same way, there will be a margin of error between the guide lines and the actual distance/course on the road.

■ When approaching three-dimensional objects
The distance guide lines are displayed according to flat surfaced objects (such as the road). It is not possible to determine the position of three-dimensional objects (such as vehicles) using the vehicle width guide lines and distance guide lines. When approaching a three-dimensional object that extends outward (such as the flatbed of a truck), be careful of the following.
● Distance guidelines
Visually check the surroundings and the area behind the vehicle. On the screen, it appears that a truck is parked at point
2 . However, in reality if you back up to point 1 , you will hit the truck. On the screen, it appears that 1 is closest and
3 is farthest away. However, in reality, the distance to and 3 is the same, and 2
1
is farther than 1 and 3 .

■ Vehicle width guide lines
Visually check the surroundings and the area behind the vehicle. In the case shown below, the truck appears to be outside of the vehicle width guide lines and the vehicle does not look as if it hits the truck. However, the rear body of the truck may actually cross over the vehicle width guide lines. In reality if you back up as guided by the vehicle width guide lines, the vehicle may hit the truck.
