Conditions to turn the high beams on/off automatically

●

When all of the following conditions are met, the high beams will be turned
on automatically (after approximately 1 second):

• The vehicle speed is approximately 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.

●

If any of the following conditions is met, the high beams will turn off automat-
ically:

• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.

■

Camera sensor detection information

●

The high beams may not be automatically turned off in the following situa-
tions:

• 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 vehicles

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
• The condition of the road (gradient, curve, condition of the road surface,

etc.)

• The number of passengers and amount of luggage in the vehicle

●

The high beams may turn on or off unexpectedly.

●

Bicycles or similar vehicles may not be detected.

●

In the following situations the system 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 pedestrians or vehicles ahead. In such
a case, it is necessary to manually switch between the high and low beams.

• 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 equal to that of headlights, tail

lights or fog lights

• When headlights or tail lights of vehicles ahead are turned off, dirty,

changing color, or not aimed properly

• When the vehicle is hit by water, snow, dust, etc. from a preceding vehi-

• 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 con-

tainer on a truck

• 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 repeatedly in an abnormal manner

• When the driver believes that the high beams may be flashing or dazzling

pedestrians or other drivers

■

Temporarily lowering sensor sensitivity

Within 30 seconds after 

, repeat pulling the headlight switch lever to the

original position then pushing it to the high beam position quickly 10 times,
