CAUTION / NOTICE / HINT

Note


  • If the cable was disconnected from and reconnected to the negative (-) battery terminal, the estimated course lines may not be displayed on the image of the area behind the vehicle. In this case, perform "Correct the Steering Angle Neutral Point" Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the parking assist monitor system may be needed Click here.

Tech Tips

Images may be unclear even in normal conditions if:


  • Electrical devices are used in the cabin (noise may occur in the image).

  • Accessories that generate radio waves have been installed (noise may occur in the image).

  • The outer mirror switch assembly is operated (noise may occur in the image).

  • The navigation receiver assembly is cold (the image immediately after turning the engine switch on (IG) may be blurred or darker than normal).

  • The camera lens is dirty with snow, mud, etc.

  • A strong beam of light, such as a sunbeam or headlight, hits the camera.

  • It is too dark around the camera (at night etc.).

  • The ambient temperature around the camera is either too high or too low.

  • The vehicle is tilted at a steep angle.

  • The rear television camera assembly lens is scratched.

  • The rear television camera assembly lens has drops of water on it or the humidity is high.

  • When the camera is used under fluorescent lights, sodium lights, or mercury lights etc., the lights and the illuminated area may appear to flicker.
