Each adjusted value for the calibration of the parking assist monitor system will be stored in the rear television camera assembly.

(2) When the lens of the rear television camera assembly is dirty, wash the lens with water and wipe it off with a soft cloth to obtain clear images. For heavy dirt, use neutral detergent to clean the lens.


(a) Notes for the rear television camera assembly

(1) The parking assist monitor system may not function properly if subjected to a severe blow by any hard object.

(2) Do not scrub the camera lens. Scrubbing may scratch the camera lens and affect the image.

(3) The cover part of the camera is made of resin. Prevent organic solvents, waxes, bond removing solvents or glass coating from adhering to the cover. If such material adheres to the cover, clean it off immediately and wash it with water.

(4) Exposing the camera to a sudden temperature change may affect proper functioning of the camera.

(5) A clear image may not appear if the camera is dirty with snow, mud, etc. In that case, wash it with water and wipe off the lens. Use a detergent to remove dirt if necessary.

(6) When washing the vehicle with a high-pressure washer, do not spray water on the rear television camera assembly or surrounding area. High-pressure water can damage the camera.

(b) Images may be unclear even in normal conditions if:

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

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

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

(4) The multi-display is cold (the image immediately after turning the engine switch on (IG) may be blurred or darker than normal).

(5) The camera lens is dirty with snow, mud, etc.

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

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

(8) The ambient temperature around the camera is either too high or too low.

(9) The vehicle is tilted at a steep angle.

(10) The rear television camera assembly lens is scratched.

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

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