Headlight control sensor (vehicles with automatic headlight system)

The sensor may not function properly if an object is placed on the sensor, or anything that blocks the sensor is affixed to the windshield.

Doing so interferes with the sensor detecting the level of ambient light and may cause the automatic headlight sys- tem to malfunction.

Vehicle speed is above approximately 21 mph (34 km/h).

The area ahead of the vehicle is dark.

There are no vehicles ahead with headlights or tail lights turned on.

When the vehicle is cut off in front of by another vehicle

When vehicles ahead are hidden from sight due to repeated curves, road dividers or roadside trees

When vehicles ahead appear from the faraway lane on wide road

When vehicles ahead have no lights

The high beam may be turned off if a vehicle ahead that is using fog lights without using the headlights is detected.

House lights, street lights, traffic signals, and illuminated billboards or signs may cause the high beam to switch to the low beams, or the low beams to remain on.

The following factors may affect the amount of time taken to turn the high beam on or off:

The brightness of headlights, fog lights, and tail lights of vehicles ahead

The movement and direction of vehicles ahead

The number of passengers and amount of luggage

The high beam may be turned on or off when the driver does not expect it.

Bicycles or similar objects may not be detected.
