Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is designed to assist your
driving using the display indications so
that the distance between your vehicle
and a vehicle ahead can be maintained
appropriately.
WARNING
Do not rely completely on the DSA
and always drive carefully:
The DSA 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. In addition, the system is
not for maintaining the distance
between your vehicle and a vehicle
ahead. If you neglect to operate the
accelerator and brake pedals correctly,
it could lead to 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.
Operation conditions
The DSA operates when all of the
following conditions are met.
The ignition is switched ON.The DSA is on.The selector lever is in a position
other than R.
The vehicle speed is about 30 km/h
(19 mph) or faster.
i-ACTIVSENSE status symbol
(warning/risk av
oidance support
system) (green) is displayed.
The vehicle ahead is a vehicle with
four wheels.
NOTE
The DSA may also operate in the
presence of motorcycles and
bicycles.
The DSA does not operate with the
following objects.
On-coming vehiclesPed e st r i an sStationary objects (such as
stopped vehicles, obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system may
not detect it correctly.
The DSA can be set to inoperable.
However, when the ignition is
switched OFF while the DSA is
canceled, the DSA is automatically
enabled the next time the ignition is
switched ON.

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.

Mazda Radar Cruise
Control with Stop & Go function (MRCC with
Stop & Go function)
*
▼ 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.
Refer to Forward Sensing Camera
(FSC) on page 4-189.
Refer to Front Radar Sensor on page
4-193.
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
may result in an accident:

The vehicle is driven on roads other
than highways.
 The vehicle is driven on roads with
sharp curves or with heavy traffic
where sufficient distances between
vehicles cannot be kept.
 The vehicle is driven on roads where
acceleration and deceleration are
frequently repeated.
 The vehicle is exiting the main lane
on an expressway to enter an
interchange, a rest area, or a parking
area.
 The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.
 The vehicle is driven on a long
downslope.
 The vehicle is driven on a steep
slope.
 A two-wheeled vehicle such as a
motorcycle or bicycle is traveling
ahead.
 The vehicle is being towed or towing
another vehicle.
 Proximity warnings activate
frequently.
Switch the MRCC with Stop & Go
function off when it is not being used.
Leaving the MRCC with Stop & Go

interchanges, service areas, and
parking areas of expressways (If you
exit an expressway while headway
control is in use, the vehicle ahead
will no longer be tracked and your
vehicle may accelerate to the set
speed).
 Slippery roads such as icy or
snow-covered roads (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
 Long, descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
 Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slip while
stopped by the stop hold control, or
it may accelerate suddenly after it
starts moving.)
 Driving under bad weather
conditions (rain, fog, and snow).
 The vehicle is driven on slippery
roads such as icy or snow-covered
