Each adjusted value for the calibration of the panoramic view monitor system will be stored in the parking assist ECU.

(3) When the lens of the 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) In the following situations, the panoramic view monitor system may not operate correctly:

(1) When driving on icy, slippery or snowy roads

(2) When using tire chains or a spare tire

(3) When a door is not fully closed

(4) When driving on a slope or rough roads

(5) When using tires other than specified

(6) When the suspension of the vehicle has been modified

(b) As the panoramic view monitor system generates the panoramic image by combining images received from the front television camera assembly, rear television camera assembly and side camera assemblies, the following phenomenon may occur:

(1) A three dimensional object may appear tilted

(2) An object above the road surface may appear farther away than it actually is, or may not be displayed at all

(3) A tall object may look as if it is coming out from between 2 combined images

(4) Depending on the brightness of the area surrounding each camera, there may be a significant difference in the brightness of the images that are used to generate the panoramic image.

(c) The image quality at the four corners of the panoramic image may be low as this is where the individual images are combined.

(d) Objects a certain height above the camera assemblies will not be displayed.

(e) Objects extremely close to the vehicle may not be displayed on the panoramic view monitor.

(f) The panoramic image may not be displayed correctly if a front door or the luggage compartment door is open.

(g) The panoramic image may not be displayed correctly if the height or inclination of the vehicle changes due to loading from passengers, luggage, etc.

(h) As the size and shape of the vehicle icon may differ from that of the actual vehicle, the position of an object relative to the vehicle icon may appear different to its actual position.


(a) Notes for each television camera assembly

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

(2) Do not scrub the cover part of the camera (resin made). Scrubbing may scratch the cover and affect the image. 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.

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

(4) 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.

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

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

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

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

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

(4) The camera lens is frosted over (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) The lens of a camera is covered with foreign matter.

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

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

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

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

(11) The area around the vehicle is not sufficiently bright.

(12) The television camera assembly lens is scratched.

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

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