Toyota CH-R: AHS (Adaptive High-beam System)

The Adaptive High-beam System uses a front camera located on the upper portion of the windshield to detect the brightness of the lights of vehicles ahead, streetlights, etc., and automatically controls the light distribution of the headlights.

WARNING

■For safe use

Do not overly rely on the Adaptive High-beam System. Always drive safely, taking care to observe your surroundings and turning the high beams on or off manually if necessary.

■To prevent unintentional operation of the Adaptive High-beam System

• When it is necessary to disable the system.

System controls

• According to the vehicle speed, the brightness and illuminated area of the high beams are adjusted.
• When driving around a curve, the system uses the high beams to brightly illuminate the direction of travel of the vehicle.
• The high beams are illuminated so that the area around a vehicle ahead is shaded. (Shaded high beam)

The shaded high beam helps ensure forward visibility while reducing the dazzling effect on the drivers of vehicles ahead.

1. Area illuminated by the high beams
2. Area illuminated by the low beams

• According to the distance to a preceding vehicle, the illuminated area of the low beams is adjusted.

Using the Adaptive High-beam System

1. Press the Adaptive High-beam System switch.

2. Turn the headlight switch to the or position.

When the headlight switch lever is in the low beam position, the AHS system will be enabled and the AHS indicator will illuminate.

■System operating conditions

• When all of the following conditions are met, the high beams will illuminate and the system will operate:
  • The vehicle speed is approximately 15 km/h (9 mph) or more.*
  • The area ahead of the vehicle is dark.

*: When driving around a curve at a vehicle speed of approximately 30 km/h (19 mph) or more, the direction of travel of the vehicle will be brightly illuminated.

• When all of the following conditions are met, the headlights will change to the shaded high beams according to the position of vehicles ahead:
  • The vehicle speed is approximately 15 km/h (9 mph) or more.
  • The area ahead of the vehicle is dark.
  • There is a vehicle ahead with lights on.
  • There are few streetlights or other lights on the road ahead.
• If any of the following conditions are met, the system will change to the low beams:
  • The vehicle speed is approximately 12 km/h (7.5 mph) or lower.
  • The area ahead of the vehicle is not dark.
  • There are many vehicles ahead.
  • There are many streetlights or other lights on the road ahead.

■Front camera detection

• In the following situations, the high beams may not be automatically changed to the shaded high beams:
  • When a vehicle cuts in front of your vehicle
  • When another vehicle crosses in front of the vehicle
  • When vehicles ahead are repeatedly detected and then hidden due to repeated curves, road dividers or roadside trees
  • When a vehicle ahead approaches from a far lane
  • When a vehicle ahead is far away
  • When a vehicle ahead has no lights
  • When the lights of a vehicle ahead are dim
  • When a vehicle ahead is reflecting strong light, such as the headlights of your vehicle
  • Situations in which the sensors may not operate properly
• The high beams may change to the shaded high beams 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 shaded high beams, cause the high beams not to change to the shaded high beams, or change the area that is not illuminated.
• The following may change the speed at which the shaded areas change or the timing at which the headlights change to the low beams:
  • The brightness of lights of vehicles ahead
  • The movement and direction of vehicles ahead
  • The distance between the vehicle and a vehicle ahead
  • When a vehicle ahead only has lights illuminated 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 light distribution control of the headlights may not match the driver's expectations
• Bicycles and other small vehicles may not be detected.
• In the following situations, the system may not be able to correctly detect the brightness of the surroundings. 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 change between the high beams and low beams.
  • When there are lights similar to headlights or tail lights in the surrounding area
  • When headlights or tail lights of vehicles ahead are turned off, dirty, changing color, or not aimed properly
  • When the headlights are repeatedly changing between the high beams and low beams.
  • When use of the high beams is inappropriate or when the high beams may be flashing or dazzling pedestrians or other drivers.
  • When the vehicle is used in an area in which vehicles travel on the opposite side of the road of the country for which the vehicle was designed, for example using a vehicle designed for right-hand traffic in a left-hand traffic area, or vice versa
  • When it is necessary to disable the system
  • Situations in which the sensors may not operate properly

■Customization

The settings of some functions can be changed.

Turning the high beams on/off manually

■ Changing to the high beams

Push the lever forward.

The AHS indicator will turn off and the high beam indicator will turn on.

Pull the lever to its original position to enable the Adaptive High-beam System again.

■ Changing to the low beams

Press the Adaptive High-beam System switch.

The AHS indicator will turn off.

Press the switch to enable the Adaptive High-beam System again.

Temporarily changing to the low beams

It is recommended to switch to the low beams when use of the high beams is inappropriate or when the high beams may cause problems or distress to other drivers or pedestrians nearby.

Pull the lever rearward and then return it to its original position.

The high beams will illuminate while the lever is pulled, however, after the lever is returned to its original position, the low beams will remain on for a certain amount of time. After this, the Adaptive High-beam System will operate.
