CAUTION / NOTICE / HINT

Note


  • When "!" mark is displayed on the multi-display after disconnecting the cable from the negative (-) battery terminal, 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 multi-terrain 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).

  • The camera lens is frosted over (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 television camera assembly lens is scratched.

  • The 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.
