Lane-keep Assist System
(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle lane
if the vehicle might be deviating.
The forward sensing camera (FSC) detects
the white lines (ye
llow lines) of the
vehicle lane in which the vehicle is
traveling and if the system determines that
the vehicle may deviate from its lane, it
operates the electric power steering to
assist the driver’s steering operation. The
system also alerts the driver by displaying
an alert on the multi-information display
and the active driving display
*. Use the
system when you drive the vehicle on
roads with white (yellow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WA R N I N G
Do not rely completely on the LAS:
 The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a driver’s
lack of caution, and over-reliance on the
system could lead to an accident.

Refer to i-ACTIVSENSE Status Symbol
(Warning/Risk Avoidance Support
System) on page 4-85.
▼ Steering Wheel Ope
ration Assist
When the system determines that the
vehicle might be deviating from its lane,
the steering wheel operation assist
operates.
The system notifies the driver of the
direction in which the system provided
steering wheel operation assistance on the
multi-information di splay and the active
driving display
*.

Forward Sensing Camera(FSC)
*
▼Forward Sensing Camera (FSC)
Your vehicle is equipped with a Forward
Sensing Camera (FSC). The Forward
Sensing Camera (FSC) is positioned near
the rearview mirro
r and used by the
following systems.
High Beam Control System (HBC)
Lane Departure Warning System
(LDWS)
Traffic Sign Recognition System (TSR)
Distance & Speed Alert (DSA)
Driver Attention Alert (DAA)
Driver Monitoring (DM)
Mazda Radar Cruise Control (MRCC)
Mazda Radar Cruise Control with Stop
& Go function (MRCC with Stop & Go
function)
Lane-keep Assist System (LAS)
Traffic Jam Assist (TJA)
Smart Brake Support (SBS)
1. Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC)
determines the conditions ahead of the
vehicle while traveling at night and detects
traffic lanes. The distance in which the
Forward Sensing Camera (FSC) can detect
objects varies depending on the
surrounding conditions.
WA R N I N G
Do not modify the suspension:
If the vehicle height or inclination is
changed, the system will not be able to
correctly detect vehicles ahead. This will
result in the system not operating normally
or mistakenly operating, which could cause
a serious accident.
CAUTION
 Do not apply accessories, stickers or film
to the windshield near the Forward
Sensing Camera (FSC).
If the area in front of the Forward
Sensing Camera (FSC) lens is obstructed,
it will cause the system to not operate
correctly. Consequently, each system
may not operate normally which could
lead to an unexpected accident.
 Do not disassemble or modify the
Forward Sensing Camera (FSC).
Disassembly or modification of the
Forward Sensing Camera (FSC) will cause
a malfunction or mistaken operation.
Consequently, each system may not
operate normally which could lead to an
unexpected accident.
 Heed the following cautions to assure
the correct operation of the Forward
Sensing Camera (FSC).

Be careful not to scratch the Forward
Sensing Camera (FSC) lens or allow it
to get dirty.
 Do not remove the Forward Sensing
Camera (FSC) cover.
 Do not place objects on the dashboard
which
reflect light.
 Always keep the windshield glass
around the camera clean by removing
dirt or fogging. Use the windshield
defroster to remove fogging on the
windshield.
 Consult an Authorized Mazda Dealer
regarding cleaning the interior side of
the windshield around the Forward
Sensing Camera (FSC).
 Consult an Authorized Mazda Dealer
before performing repairs around the
Forward Sensing Camera (FSC).
 The Forward Sensing Camera (FSC) is
installed to the windshield. Consult an
Authorized Mazda Dealer for
windshield repair and replacement.
 When cleaning the windshield, do not
allow glass cleaners or similar cleaning
fluids to get on the Forward Sensing
Camera (FSC) lens. In addition, do not
touch the Forward Sensing Camera
(FSC) lens.
 When performing repairs around the
rearview mirror, consult an Authorized
Mazda Dealer.
 Consult an Authorized Mazda Dealer
regarding cleaning of the camera lens.Do not hit or apply strong force to the
Forward Sensing Camera (FSC) or the
area around it. If the Forward Sensing
Camera (FSC) is severely hit or if there
are cracks or damage caused by
flying
gravel or debris in the area around it,
stop using the following systems and
consult an Authorized Mazda Dealer.
 High Beam Control System (HBC)
 Lane Departure Warning System
(LDWS)
 Traffic Sign Recognition System
(TSR)
 Distance & Speed Alert (DSA)
 Driver Attention Alert (DAA)
 Driver Monitoring (DM)
 Mazda Radar Cruise Control (MRCC)
 Mazda Radar Cruise Control with
Stop & Go function (MRCC with Stop
& Go function)
 Lane-keep Assist System (LAS)
 Traffic Jam Assist (TJA)
 Smart Brake Support (SBS)
 The direction in which the Forward
Sensing Camera (FSC) is pointed has
been finely adjusted. Do not change
the installation position of the Forward
Sensing Camera (FSC) or remove it.
Otherwise, it could result in damage or
malfunction.
 Always use tires for all wheels that are of
the specified size, and the same
manufacturer, brand, and tread pattern.
In addition, do not use tires with
significantly different wear patterns on
the same vehicle as the system may not
operate normally.
