Lane Departure Warning
System (LDWS)
*
▼Lane Departure Warning System
(LDWS)
The LDWS alerts the driver that the
vehicle may be deviating from its lane.
The system detects the white (yellow)
lines on the traffic lane using the
forward sensing camera (FSC) and if it
determines that the vehicle might be
deviating from its lane, it
notifies the
driver by the LDWS.
Refer to Forward Sensing Camera
(FSC) on page 4-216.
Use the LDWS when you drive the
vehicle on roads with white (yellow)
lines.
1. Forward sensing camera (FSC)
WARNING
Do not rely completely on the
LDWS:
¾The 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.
¾The functions of the LDWS have
limitations. Always stay on course
using the steering wheel and drive
with care.
CAUTION
Heed the following cautions so that
the LDWS can operate normally.
¾Do not modify the vehicle's
suspensions.
¾Always use tyres of the
specified type
and size for the front and rear
wheels. Consult an expert repairer
(we recommend an Authorised
Mazda Repairer) for tyre
replacement.
NOTE
The system may not operate normally
under the following conditions.
xThe white (yellow) lane lines are less
visible because of dirt or paint
flaking.
xWhite (yellow) lane lines are less
visible because of bad weather (rain,
fog, or snow).
xThe 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.
xThe 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.

WARNING
Do not rely completely on DAA and
always drive carefully:
The DAA detects driver fatigue and
decreased attentiveness and
encourages the driver to take a rest,
however, it is not designed to prevent
the vehicle from straying. If you rely too
much on the DAA it could lead to an
accident. Drive carefully and operate
the steering wheel appropriately.
In addition, the system may not be
able to detect driver fatigue and
decreased attentiveness correctly
depending on the
traffic and driving
conditions. The driver must take
sufficient rest in order to drive safely.
NOTE
xThe DAA operates when all of the
following conditions are met.
xThe vehicle speed is about 65 to
140 km/h (41 to 86 mph).
xThe system detects white (yellow)
lane lines.
xThe system has completed learning
of the driver’s driving data after 60
minutes have passed since the
driver began driving vehicle.
xThe DAA does not operate under the
following conditions.
xThe vehicle speed is less than
about 65 km/h (41 mph).
xThe vehicle speed exceeds about
140 km/h (86 mph)
xThe vehicle is making a sharp turn.xThe vehicle is changing lanes.xThe system cannot detect white
(yellow) lane lines.
xThe DAA may not operate normally
under the following conditions.
xWhite (yellow) lane lines are less
visible because of dirt or fading/
patchiness.
xThe vehicle is jolted or swayed
continuously by strong winds or
rough roads.
xThe vehicle is driven aggressively.xWhen making frequent lane
changes.
xThe vehicle is making a curve.xThe DAA detects driver fatigue and
decreased attentiveness based on
the driving data when the vehicle is
driven at about 65 to 140 km/h (41
to 86 mph) for about 20 minutes.
The driving data will be reset under
the following conditions.
xThe vehicle is stopped for 15
minutes or longer.
xThe vehicle is driven at less than
about 65 km/h (41 mph) for
about 30 minutes.
xThe ignition is switched
off.xAfter the DAA has displayed the first
message encouraging rest, it does

WARNING
Do not rely completely on the DM
and always drive carefully:
The DM is a system which detects
driver fatigue and sleepiness, and
encourages the driver to take a rest.
This is not designed to prevent driver
fatigue and sleepiness, and
over-reliance on the system could lead
to an accident. Drive carefully and turn
the steering wheel appropriately.
In addition, the system may not be
able to detect driver fatigue and
sleepiness correctly depending on the
traffic and driving conditions. The
driver must take
sufficient rest in order
to drive safely.
Operation conditions
The DM begins monitoring after 20
minutes have passed since the driver
began driving the vehicle and when
the vehicle speed is about 5 km/h (3
mph) or faster.
NOTE
xIf the vehicle speed decreases to less
than about 5 km/h (3 mph) while
the DM is monitoring, the DM stops
monitoring for 6 minutes even if the
vehicle speed returns to about 5
km/h (3 mph) or faster.
xIf the driver monitoring camera does
not recognise the driver correctly, the
DM may not monitor correctly.
Refer to Driver Monitoring Camera
on page 4-226.
xAfter the DM has displayed the
first
message encouraging the driver to
take a rest, it does not display it
again during the following periods.
xAfter displaying the warning
pattern (caution), the next warning
pattern (caution) is not displayed
until 45 minutes have passed.
xAfter displaying the warning
pattern (warning), the next
warning pattern (warning) is not
displayed until 15 minutes have
passed.
xAfter displaying the warning
pattern (warning), the next
warning pattern (caution) is not

starts moving , the multi-information
display vehicle-ahead indication
flashes to urge the driver to resume
driving. If you do not resume driving
after the indicator light flashes, a
sound is activated to urge you to
resume driving.
Cruising & Traffic Support
(CTS)
*
▼Cruising & Traffic Support (CTS)
The CTS is a system which consists of a
headway control function and a
steering assist function for reducing
driver fatigue during traffic jams when
driving on expressways or highways.
This system performs headway control
to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to use the
accelerator or brake pedal. Even
further, with the steering assist
function, when vehicle lane lines are
detected, the function assists the driver
in keeping the vehicle within the lane
lines. If lane lines are not detected, the
function provides the driver driving
assistance in keeping the vehicle along
the motion path with the vehicle
ahead.
WARNING
Do not rely completely on CTS:
¾The CTS is not an automated driving
system. In addition, the functions
have limitations. Do not rely
completely on the system and always
stay on course using the steering
wheel.
¾Set a vehicle speed within the speed
limit according to the road
conditions and the weather
conditions.
