Turn the light switch to the position.

The engine switch is in the “ON” position (vehicles without a smart key system) or IGNITION ON mode (vehicles with a smart key system).

Camera sensor detection information

• High beam may not be automatically turned off in the following situations:

• When oncoming vehicles suddenly appear from a curve.
• When the vehicle is cut in front of by another.

• High beam may be turned off if an oncoming vehicle that is using fog lights without using the headlights is detected.
• Houselights, streetlights, red traffic signals, and illuminated billboards or signs may cause the high beam to turn off.
• The following factors may affect the amount of time taken to turn high beam on or off:

• The brightness of headlights, fog lights, and tail lights of oncoming and preceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage

• High beam may be turned on or off when unexpected by the driver.
• In the situations below, the system may not be able to correctly detect the surrounding brightness levels, and may flash or expose nearby pedestrians to the high beam. Therefore, you should consider turning the high beam on or off manually rather than relying on the Automatic High Beam system.

• 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.
• 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 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 vehicle’s headlights are damaged or dirty.
• The vehicle is lifting or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.

When the warning message is shown on the multi-information display

Temporary lowering sensor sensitivity

The sensitivity of the sensor can be temporarily lowered.

To lower the sensitivity, push and hold on the inside rear view mirror for
15 to 20 seconds, and release. The indicator light on the inside rear view mirror will flash to indicate that the sensitivity has been lowered.

When the engine switch is turned to the “LOCK” position (vehicles without a smart key system) or turned off (vehicles with a smart key system), the sensitivity will be returned to its normal level.
