When all of the following condi-

tions are met, the high beams will

be turned on automatically (after

approximately 1 second):

• The vehicle speed is approxi-

mately 21 mph (34 km/h) or more.

• The area ahead of the vehicle is

dark.

• There are no vehicles ahead with

headlights or tail lights turned on.

• There are few streetlights on the

road ahead.

road ahead.

■

Front camera detection infor-

mation

●

The high beams may not be auto-

matically turned off in the following

situations:

• When a vehicle suddenly appears

from around a curve

• When the vehicle is cut in front of

by another vehicle

• When vehicles ahead cannot be

detected due to repeated curves,

road dividers or roadside trees

• When vehicles ahead appear in a

faraway lane on a wide road

• When the lights of vehicles ahead

are not on

●

The high beams may be turned off

if a vehicle ahead that is using fog

lights without its headlights turned

on is detected.

●

House lights, street lights, traffic

signals, and illuminated billboards

or signs and other reflective

objects may cause the high

beams to change to the low

beams, or the low beams to

remain on.

●

The following factors may affect

the amount of time taken for the

high beams to turn on or off:

• The brightness of the headlights,

fog lights, and tail lights of vehi-

cles ahead

• The movement and direction of

vehicles ahead

• When a vehicle ahead only has

operational lights on one side

• When a vehicle ahead is a two-

wheeled vehicle

not be detected.

●

In the following situations the sys-

tem may not be able to correctly

detect the surrounding brightness

level. This may cause the low

beams to remain on or the high

beams to flash or dazzle pedestri-

ans or vehicles ahead. In such a

case, it is necessary to manually

switch between the high and low

beams.
