• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are
changing color, or have are not aimed properly.
• When driving through an area of intermittently 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 tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
