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
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.

Mazda Radar Cruise
Control (MRCC)
*
▼Mazda Radar Cruise Control
(MRCC)
The MRCC system is designed to
maintain headway control*1 with a
vehicle ahead according to your
vehicle's speed using a front radar
sensor to detect the distance to the
vehicle ahead and a preset vehicle
speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the
distance between your vehicle and
the vehicle ahead detected by the
MRCC system.
Additionally, if your vehicle starts
closing in on the vehicle ahead such as
if the vehicle ahead brakes suddenly, a
warning sound and a warning
indication in the display are activated
simultaneously to alert you to maintain
a sufficient distance between the
vehicles.
Also refer to the following before using
the MRCC.

WARNING
Do not rely completely on the MRCC:
The MRCC system has detection
limitations depending on the type of
vehicle ahead and its conditions, the
weather conditions, and the road
conditions. Additionally, the system
may be unable to decelerate
sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the
brakes suddenly or another vehicle
cuts into the driving lane, which could
result in an accident.
Always drive carefully and verify the
surrounding conditions and depress
the brake pedal or accelerator pedal
while keeping a safe distance from
vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the
following locations. Using the MRCC
system at the following locations may
result in an unexpected accident:
¾General roads other than highways
(Driving under these conditions
using the MRCC system is not
possible.)
¾Roads with sharp curves and where
vehicle traffic is heavy with
insufficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the MRCC is
not possible).
¾When entering and exiting
interchanges, service areas, and
parking areas of highways (If you exit
a highway while headway control is
in use, the vehicle ahead will no
longer be tracked and your vehicle
may accelerate to the set speed).
¾Slippery roads such as ice or
snow-bound roads (Tyres could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
¾Long , descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
¾Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly.)
¾Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
