(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 panoramic view monitor system may be needed.

HINT:

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

(3) A clear image may not be displayed if there is foreign matter such as water drops, snow or mud on the television camera lens. In such a case, wash the lens with a large amount of water and then wipe it with a soft wet cloth. Do not scrub the camera lens as scrubbing may scratch the camera lens and affect the quality of the image.

PRECAUTIONS FOR PANORAMIC VIEW MONITOR SYSTEM

(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, 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.

NOTES FOR EACH TELEVISION CAMERA ASSEMBLY

(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) The cover part of the camera is made of resin. If any organic solvent, degreaser, wax or glass coating contacts the cover, immediately wipe it off and wash the cover with water or cracks may develop.

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

(4) A clear image may not be displayed if there is foreign matter such as water drops, snow or mud on the television camera lens. In such a case, wash the lens with a large amount of water and then wipe it with a soft wet cloth. Do not scrub the camera lens as scrubbing may scratch the camera lens and affect the quality of the image.

(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.

NOTICE OF REAR CAMERA DETECTION FUNCTION

(a) The rear camera detection function may not be able to detect some pedestrians correctly, such as the following

(1) Pedestrians who are squatting

(2) Pedestrians who are lying down

(3) Pedestrians who are running

(4) Pedestrians who suddenly enter the detection area

(5) Pedestrians riding a bicycle, skateboard, or other light vehicle

(6) Pedestrians wearing unusual clothing, such as a costume

(7) Pedestrians whose body is partially hidden by a cart or other object

(8) Pedestrians who are obscured by darkness, such as at night

(b) The rear camera detection function may not be able to detect pedestrians correctly in the following conditions:

(1) When visibility is poor due to rain, snow, fog, nighttime, etc.

(2) When foreign matter such as water or snow is on the television camera assembly

(3) When a bright light such as the sun or headlights of another vehicle shines directly into the television camera assembly

(4) When the surrounding brightness changes suddenly such as at the entrance/exit of a garage or underground parking lot

(c) The rear camera detection function may accidentally detect the following objects as pedestrians:

(1) A three dimensional object such as a pole, traffic cone, fence or parked vehicle

(2) A moving vehicle such as a car or motorcycle

(3) A moving object such as a flag, smoke, raindrops, snow or puddle

(4) A pattern on the road surface such as white lines, pedestrian crossings, cobblestones, tram rails, traces of repair, fallen leaves or gravel

(5) A metal cover (grating) or drainage ditch

(6) The edge of the road, or a bump in the road

(7) A reflection in a puddle or on a wet road surface

(8) A shadow on the road

(d) The rear camera detection function may accidentally detect an object in the following conditions:

(1) When driving over a joint in the road surface

(2) When the vehicle is significantly tilted, such as when carrying a heavy load or during sudden braking

(3) When the vehicle is on varying gradients

(4) When the vehicle is equipped with lowered suspension or tires with a diameter different to that of the original

(5) When the height of the vehicle has drastically changed (the nose is tilted up or down)

(6) When an electronic component such as a fog light is installed near the television camera assembly

(7) When a bumper protector such as an additional trim strip is installed to the rear bumper assembly

(8) When the television camera assembly is misaligned

(9) When a towing eyelet is installed to the rear bumper assembly

(10) When foreign matter such as water or snow is on the television camera assembly

(11) When water is flowing over the television camera assembly

(12) When there is a flashing light in the detection area, such as the hazard lights of another vehicle.

(e) The warning of the rear camera detection function may be difficult to notice in the following situations:

(1) When the multi-display screen is not operating correctly due to extremely high or low temperatures in the cabin.

(2) When loud noises make it difficult to hear the RCTA buzzer (blind spot monitor buzzer) such as when the audio system volume is high.
