▼Adaptive Front Lighting System
(AFS)
The adaptive front lighting system (AFS)
automatically adjusts the headlight beams
to the left or right in conjunction with the
operation of the steering wheel after the
headlights have been turned on and the
vehicle speed is about 2 km/h (2 mph) or
higher.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Exterior Light Warning
Indication/Warning Light on page 7-33.
NOTE
The Adaptive Front Lighting System (AFS)
can be switched to operable/inoperable
using the personalization function.

High Beam ControlSystem (HBC)
*
▼ High Beam Control System (HBC)
The 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 Forward Sen
sing Camera (FSC)
on page 4-198.
While driving the vehicle at a speed of
about 30 km/h (19 mph) or more, 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 th e 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 headlight high-beam indicator light
turns on while the high beams are on.
1. Forward Sensing Camera (FSC)*1
*1 The recognition distance of the Forward Sensing
Camera (FSC) varies according to the
surrounding conditions.
The warning light turns on when the
system has a malfunction.
Refer to High Be am Control System
(HBC) Warning Indication/Warning Light
(Amber) on page 7-33.
CAUTION
 Do not adjust the vehicle height, modify
the headlight units, or remove the
camera, otherwise the system will not
operate normally.
 Do not rely excessively on the HBC and
drive the vehicle while paying sufficient
attention to safety. Switch the headlights
between the high beams and low beams
manually if necessary.
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 traffic conditions.
When there are sources of light in the
area such as street lamps, illuminated
signboards, and traffic signals.
When there are reflective objects in the
surrounding area such as reflective
plates and signs.
When visibility is reduced under rain,
snow and foggy conditions.
When driving on roads with sharp turn
or hilly terrain.

Lane Departure WarningSystem (LDWS)
*
▼Lane Departure Warning System
(LDWS)
The LDWS alerts the driver that the
vehicle may be deviating from its lane. If
the white (yellow) lin
es on the traffic lane
are detected using the Forward Sensing
Camera (FSC) and the system determines
that the vehicle may be deviating from its
lane, it notifies the driver by flashing the
LDWS warning light and activating the
LDWS warning beep, and by the
multi-information display.
Refer to Forward Sen sing Camera (FSC)
on page 4-198.
Use the LDWS when you drive the vehicle
on roads with white (yellow) lines.

WA R N I N G
Do not rely completely on the LDWS.
 The LDWS system is not designed to
compensate for a driver’s lack of caution
and relying too much on the system
could lead to an accident.
 The functions of the LDWS have
limitations. Always stay on course using
the steering wheel and drive with care.
 Do not use the LDWS under the following
circumstances, otherwise it may result in
an accident.
 The vehicle is driven on slippery roads
such as icy or snow-covered roads, and
unpaved roads.
 Tires of a different specified size are
used, such as a temporary spare tire.
 Tires with insufficient tread are used.
 The tire pressures are not adjusted to
the specified pressure.
 The vehicle is being used to tow a
camper or boat trailer.
 Tire chains are used.
 The vehicle is driven on roads with lane
lines other than white (yellow) lines,
such as an expressway.
CAUTION
Heed the following cautions so that the
LDWS can operate normally.
Do not modify the vehicle's suspensions.
 Always use wheels of the specified type
and size for the front and rear wheels.
Consult an Authorized Mazda Dealer for
tire replacement.

White (yellow) lane lines are less visible
because of bad weather (rain, fog, or
snow).
The vehicle is driven on a temporary
lane or section with a closed lane
resulting from construction where there
might be multiple white (yellow) lane
lines, or they are interrupted.
The camera picks up an obscure line,
such as a temporary line being used for
construction, or because of shade,
unmelted snow, or grooves filled with
water.
The surrounding brightness suddenly
changes such as when entering or
exiting a tunnel.
Back-light is reflected off the road
surface.

the road or a junction.
The shade of a guardrail parallel to a
white (yellow) lane line is cast on the
road.
The illumination of the headlights is
weakened because of dirt or the optical
axis is deviated at night.
The road is excessively uneven.
The vehicle is shaken after hitting a
road bump.
A vehicle in front of your vehicle is
running near a white (yellow) lane line
making it less visible.
