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
The DAA operates when all of the
following conditions are met.
The vehicle speed is about 65 to
140 km/h (41 to 86 mph).
The system detects white (yellow)
lane lines.
The system has completed learning
of the driver’s driving data after 60
minutes have passed since the
driver began driving vehicle.
The DAA does not operate under the
following conditions.
The vehicle speed is less than
about 65 km/h (41 mph).
The vehicle speed exceeds about
140 km/h (86 mph)
The vehicle is making a sharp turn.The vehicle is changing lanes.The system cannot detect white
(yellow) lane lines.
The DAA may not operate normally
under the following conditions.
White (yellow) lane lines are less
visible because of dirt or fading/
patchiness.
The vehicle is jolted or swayed
continuously by strong winds or
rough roads.
The vehicle is driven aggressively.When making frequent lane
changes.
The vehicle is making a curve.The 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.
The vehicle is stopped for 15
minutes or longer.
The vehicle is driven at less than
about 65 km/h (41 mph) for
about 30 minutes.
The ignition is switched off.After the DAA has displayed the first
message encouraging rest, it does
not display the next one until 60
minutes have passed.
▼Driver Attention Alert (DAA)
Display
When the system detects driver fatigue
or decreased attentiveness, it activates
the warning sound and displays an
alert in the multi-information display.

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
If the vehicle speed decreases to less
than about 5 km/h (3 mph) while
the DM is monitoring, the DM stops
monitoring for 6 mi nutes even if the
vehicle speed returns to about 5
km/h (3 mph) or faster.
If the driver monitoring camera does
not recognize the driver correctly, the
DM may not monitor correctly.
Refer to Driver Monitoring Camera
on page 4-200.
After the DM has displayed the first
message encouraging the driver to
take a rest, it does not display it
again during the following periods.
After displaying the warning
pattern (caution), the next warning
pattern (caution) is not displayed
until 45 minutes have passed.
After displaying the warning
pattern (warning), the next
warning pattern (warning) is not
displayed until 15 minutes have
passed.
After displaying the warning
pattern (warning), the next
warning pattern (caution) is not
displayed until 45 minutes have
passed.
▼ Driver Monitoring (DM) Display
When the Driver Monitoring (DM)
detects driver fatigue or sleepiness, it
activates the warning sound and
displays an alert in the instrument
cluster.

Resume driving information
If you do not resume driving within a
few seconds after the vehicle ahead
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.
Tra ffi c Ja m A s s i s t ( TJ A )*
▼Tra ffi c
Jam Assist (TJA)
The TJA 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 TJA:

The TJA 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.
 Set a vehicle speed within the speed
limit according to the road
conditions and the weather
conditions.

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 (yellow 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)
WARNING
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.
The functions of the LAS have
limitations. Always stay on course
using the steering wheel and drive
with care.
 Do not use the LAS 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 LAS 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.
NOTE
The system may not operate normally
under the following conditions.
The white (yellow) lane lines are less
visible because of dirt or paint
flaking.
White (yellow) lane lines are less
visible because of bad weather (rain,
fog, or snow).
