CAUTION / NOTICE / HINT

NOTICE:
·

When the "!" mark is displayed on the multi-display after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point.

HINT:
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.
