AHB (Automatic High Beam)
* : If equipped
The Automatic High Beam uses an in-vehicle front camera to assess the brightness of streetlights, the lights of a vehicle ahead, etc., and automatically turns the high beam on or off as necessary
WARNING
- Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to observe your surroundings and turning the high beam on or off manually if necessary.
- To prevent incorrect operation of the Automatic High Beam system
Do not overload the vehicle.
Activating the Automatic High Beam system
1 Press the Automatic High Beam switch.
2 Turn the headlight switch to the or position.
The AHB indicator will come on when the system is operating.
High beam automatic turning on or off conditions
When all of the following conditions are met, the high beam will be automatically turned on (after approximately 1 second):
- Vehicle speed is above approximately 30 - 40 km/h (19 - 25 mph)* .
- 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 are met, the high beam will be automatically turned off:
- Vehicle speed drops below approximately 25 - 30 km/h (16 - 19 mph)* .
- The area ahead of the vehicle is not dark.
- Vehicles ahead have headlights or tail lights turned on.
- There are many streetlights on the road ahead. * : The vehicle speed at which the high beams are automatically turned on/off may vary depending on the country for which the vehicle is approved.
Front camera detection information
The 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 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
- 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
The high beam may be turned on or off when the driver does not expect it.
Bicycles or similar objects may not be detected.
In the situations shown below, the system may not be able to accurately detect surrounding brightness levels. This may cause the low beams to remain on or the high beams to cause problems for pedestrians, vehicles ahead or other parties. In these cases, manually switch between the high and low beams.
- 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 front camera is deformed or dirty.
- Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
- Vehicles ahead have headlights or tail lights that are either switched off, dirty, changing color, or have improperly adjusted aim. • 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 listing or titling, due to a flat tire, a trailer being towed etc.
- The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.
- The vehicle is used in a territory in which vehicles travel on the opposite side of the road of the country for which the vehicle is approved, for example using a vehicle designed for right-hand traffic in a lefthand traffic territory, or vice versa.
Turning the high beam on/off manually
Switching to high beam
Push the lever away from you. The AHB indicator will turn off and the high beam indicator will turn on. Pull the lever to its original position to activate the Automatic High Beam system again.
Switching to low beam
