Lexus parking assist monitor precautions

■ Area displayed on screen The parking assist monitor displays an image of the view from the bumper of the rear area of the vehicle.

The image of the Lexus parking assist monitor can be adjusted.

  • 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. 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 on the monitor.
  • If your vehicle is equipped with a backlit license plate, it may interfere with the display.

Lexus RX. Using the driving support systems

■ Lexus parking assist monitor camera The camera for the parking assist monitor is located above the license plate.

Lexus RX. Using the driving support systems

  • 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 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 guidelines 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 further 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 guidelines and the actual distance/course on the road.

Lexus RX. Using the driving support systems

  • When any part of the vehicle sags
    When any part of the vehicle sags due to the number of passengers or the distribution of the load, there is a margin of error between the guide lines on the screen and the actual distance/course on the road.

Lexus RX. Using the driving support systems

■ When approaching three-dimensional objects The estimated course lines target a flat surfaced objects (such as the road). It is not possible to determine the position of three-dimensional objects (such as vehicles) using the estimated course 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.

  • Estimated course lines
    Visually check the surroundings and the area behind the vehicle.

    In the case shown in the illustration, the truck appears to be outside of the estimated course lines and the vehicle does not look as if it will hits the truck. However, the rear body of the truck may actually cross over the estimated course lines. In reality if you back up as guided by the estimated course lines, the vehicle may hit the truck.

Lexus RX. Using the driving support systems

  • Distance guidelines
    Visually check the surroundings and the area behind the vehicle.

    On the screen, it appears that a truck is parking 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 1 and 3 is the same and 2 is farther than 1 and 3.

WARNING

■When using the Lexus parking assist monitor system The parking assist monitor is a supplemental device intended to assist the driver when backing up. When backing up, be sure to check visually behind and all around the vehicle before proceeding.

Observe the following precautions to avoid an accident that could result in death or serious injuries.

  • Never depend on the parking assist monitor entirely when backing up. The image and the position of the guide lines displayed on the screen may differ from the actual state.

    Use caution, just as you would when backing up any vehicle.

  • Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
  • If you seem likely to hit nearby vehicles, obstacles, people or mount the shoulder, depress the brake pedal to stop the vehicle.
  • The instructions given are only guidelines.

    When and how much to turn the steering wheel will vary according to traffic conditions, road surface conditions, vehicle condition, etc. when parking. It is necessary to be fully aware of this before using the parking assist system.

  • When parking, be sure to check that the parking space will accommodate your vehicle before maneuvering into it.
  • Do not use the parking assist monitor in the following cases:
    • On icy or slick road surfaces, or in snow
    • When using tire chains or emergency tires
    • When the back door is not closed completely
    • On roads that are not flat or straight, such as curves or slopes.
  • In low temperatures, the screen may darken or the image may become faint. The image could distort when the vehicle is moving, or you may become unable to see the image on the screen. Be sure to check direct visually and with the mirrors all around the vehicle before proceeding.
  • If the tire sizes are changed, the position of the guide lines displayed on the screen may change.
  • The camera uses a special lens. The distances between objects and pedestrians that appear in the image displayed on the screen will differ from the actual distances.
  • Estimated course line display mode: If the steering wheel is straight and the vehicle width guide lines and the estimated course lines are not in alignment, have the vehicle inspected by your Lexus dealer.

NOTICE

■ How to use the camera

  • The parking assist monitor may not operate properly in the following cases.
    • If the back of the vehicle is hit, the position and mounting angle of the camera may change.
    • As the camera has a water proof construction, do not detach, disassemble or modify it. This may cause incorrect operation.
    • When cleaning the camera lens, flush the camera with a large quantity of water and wipe it with a soft and wet cloth. Strongly rubbing the camera lens may cause the camera lens to be scratched and unable to transmit a clear image.
    • Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to the camera. If this happens, wipe it off as soon as possible.
    • If the temperature changes rapidly, such as when hot water is poured on the vehicle in cold weather, the system may not operate normally.
    • When washing the vehicle, do not apply intensive bursts of water to the camera or camera area. Doing so may result in the camera malfunctioning.
    • When the camera is used under fluorescent lights, sodium light or mercury light etc., the lights and the illuminated areas may appear to flicker.
  • Do not expose the camera to strong impact as this could cause a malfunction.

    If this happens, have the vehicle inspected by your Lexus dealer as soon as possible.
