Driver Attention Alert
(DAA)
*
▼Driver Attention Alert (DAA)
The DAA is a system which detects
driver fatigue and decreased
attentiveness, and encourages the
driver to take a rest.
When the vehicle is driven inside traffic
lane lines at about 65 to 140 km/h
(41 to 86 mph), the DAA estimates the
amount of accumulated fatigue and
decreased attentiveness of the driver
based on the information from the
Forward Sensing Camera (FSC) and
other vehicle information, and
encourages the driver to take a rest
using an indication on the
multi-information display and a
warning sound.
Use the DAA on expressways or
highways.
Refer to Forward Sensing Camera
(FSC) on page 4-189.

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.

▼ Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
The MRCC with Stop & Go function is
a system designed to enable
constant-speed driving at a set speed
and headway control to maintain a
constant distance with a vehicle ahead
according to your vehicle speed. The
system automatically accelerates,
decelerates, and stops your vehicle
without you having to depress the
accelerator or brake pedal.

Also refer to the following information
before using the MRCC with Stop &
Go function.

WARNING
Do not rely completely on the MRCC
with Stop & Go function and always
drive carefully:
The MRCC with Stop & Go function
may not be able to detect a vehicle
ahead depending on the type of
vehicle and its conditions, the weather
conditions, and the road conditions.
Additionally, the system might be
unable to decelerate sufficiently if the
vehicle ahead applies the brakes
suddenly or another vehicle cuts into
your lane, which could result in an
accident.
Always check the surrounding
conditions and depress the brake
pedal or accelerator pedal while
keeping a safe distance from a vehicle
ahead or a vehicle following behind
you.
Do not use the system under the
following conditions. Otherwise, it

Traffic Jam Assist (TJA)*
▼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.
The TJA may not be able to detect a
vehicle ahead depending on the type
of vehicle ahead and its conditions,
the weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate
sufficiently if a vehicle ahead applies
the brakes suddenly, another vehicle
cuts into the driving lane, or the difference in vehicle speed between
your vehicle and the vehicle ahead is
larger, which could result in an
accident. Check the surrounding
conditions and always drive carefully
while keeping a safe distance from
vehicles ahead and on-coming
vehicles.

For the purposes of safety, switch the
TJA off when it is not being used.
Leaving the TJA turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.

Do not use the TJA under the
following conditions. Otherwise, it
may result in an accident.
 General roads other than
expressways or highways (Driving
under these conditions using the TJA
is not possible.)
 Roads 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 TJA is not
possible).
