●In the following situations the system may not be able to correctly detect the surround- ing brightness level. This may cause the low beams to remain on or the high beams to flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (heavy rain, snow, fog, sandstorms, etc.) • When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged • When the camera sensor is deformed or dirty• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equa l to that of headlights, tail lights or fog lights• When headlights or tail lights of vehicles ah ead are turned off, dirty, changing color,
or not aimed properly • When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle• When driving through an area of interm ittently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads, gravel roads, etc.)• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object ahead of the vehicle, such as a sign or mirror • When the back of a preceding vehicle is highly reflective, such as a container on atruck
• When the vehicle's headlights are damaged or dirty, or are not aimed properly • When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc. • When the headlights are changed between the high beams and low beams repeat-
edly in an abnormal manner • When the driver believes that the high beams may be flashing or dazzling pedestri-ans or other drivers
• When the vehicle is used in an area in which vehicles travel on the opposite side of the road of the country for which the vehicle was designed, for example using a vehi-
cle designed for right-hand traffic in a left-hand traffic area, or vice versa
