INSPECTION PROCEDURE

NOTICE:

1. 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).
   
2. 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).
   

HINT:

Images may be unclear even in normal conditions if:

1. Electrical devices are used in the cabin (noise may occur in the image).
   
2. The camera lens is frosted over (the image immediately after turning the engine switch on (IG) may be blurred or darker than normal).
   
3. The camera lens is dirty with snow, mud, etc.
   
4. A strong beam of light, such as a sunbeam or headlight, hits the camera.
   
5. It is too dark around the camera (at night, etc.).
   
6. The ambient temperature around the camera is either too high or too low.
   
7. The vehicle is tilted at a steep angle.
   
8. The television camera assembly lens is scratched.
   
9. The television camera assembly lens has drops of water on it or the humidity is high.
   
10. When the camera is used under fluorescent lights, sodium lights, or mercury lights, etc., the lights and the illuminated area may appear to flicker.
    

1. Check if the same malfunction occurs when the multi-terrain monitor screen is displayed.
