Toyota CH-R: AHB (Automatic High Beam)
The Automatic High Beam
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
changes the head lights
between the high beams and
low beams.
WARNING

High Beam. Always drive safely, taking
care to observe your surroundings

■Front camera detection
- In the following situations, the high

- 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 own headlights
- Situations in which the sensors may
not operate properly
- The headlights may change to the low
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 may cause the high beams to
change to the low beams, or the low
beams to remain on.
- The following may change 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

- The headlights may change between
the high beams and low beams unexpectedly.
- 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
