Mazda 2: High Beam Control System (HBC)
The High Beam Control System (HBC) determines the conditions in front of the
vehicle
using the Forward Sensing Camera (FSC) while driving in darkness to
automatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-37 .
While driving the vehicle at a speed of about 30 km/h (18 mph), the headlights
are switched
to high beams when there are no vehicles ahead or approaching in the opposite
direction.
The system switches the headlights to low beams when one of the following
occurs:
- The system detects a vehicle or the headlights/lights of a vehicle
approaching in the
opposite direction.
- The vehicle is driven on roads lined with streetlamps or on roads in
well-lit cities and
towns.
- The vehicle is driven at less than about 20 km/h (12 mph).

The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-38 .
CAUTION
Do not adjust the vehicle height, modify the headlight units, or
remove the camera,
otherwise the system will not operate normally.
NOTE
The timing in which the system switches the headlights changes under the
following
conditions. If the system does not switch the headlights appropriately, manually
switch
between high and low beams according to the visibility as well as road and
traffi c
conditions.
- When there are sources of light in the area such as street lamps,
illuminated
signboards, and traffi c signals.
- When there are refl ective objects in the surrounding area such as
refl ective plates and
signs.
- When visibility is reduced under rain, snow and foggy conditions.
- When driving on roads with sharp curves or hilly terrain
- When the headlights/rear lamps of vehicles in front of you or in the
opposite lane are
dim or not illuminated.
- When there is suffi cient darkness such as at dawn or dusk.
- When the luggage compartment is loaded with heavy objects or the rear
passenger
seats are occupied.
- When visibility is reduced due to a vehicle in front of you spraying
water from its tyres
onto your windscreen.
To Operate the System
The High Beam Control System (HBC)
operates to switch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position. At the same time,
the High Beam Control System (HBC)
indicator light (green) in the instrument
cluster illuminates.
The High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area.
NOTE
- When the vehicle speed is 30 km/h
(18 mph) or higher, the headlights
automatically switch to high beams
when there are no vehicles ahead
or approaching in the opposite
direction.
When the vehicle speed is less
than about 20 km/h (12 mph), the
High Beam Control System (HBC)
switches the headlights to low
beams.
- The low beams may not switch to
high beams when cornering.
- Operation of the High Beam Control
System (HBC) function can be
disabled. Refer to Personalisation
Features on page 9-13 .
