▼Excessive Speed Warning
If the vehicle speed exceeds the speed limit sign displayed in the active driving display/
instrument cluster, the area aro und the speed limit sign flashes in amber and the warning
sound is activated at the same time. If the vehicle speed conti nues to exceed the displayed
speed limit sign, the indication stops flashing and remains on. Check the surrounding
conditions and adjust the vehicle speed to the legal speed using the appropriate operation
such as depressing the brake pedal.

Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintai
ning the appropriate
distance between vehicles and notifies the
driver of the recommended, safe distance
to maintain with a vehicle ahead. The
system measures the distance between
your vehicle and a vehicle ahead while the
vehicle speed is about 30 km/h (19 mph)
or faster. If the distance between your
vehicle and a vehicle ahead is close, the
system alerts the driver of a possible
collision using an indication on the
display.
WA R N I N G
Do not rely completely on the DSA.
The ability of the system to detect a vehicle
ahead is limited depending on the type of
vehicle ahead, weather conditions, or
traffic 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 safety of the
surrounding area and depress the brake
pedal or accelerator pedal while keeping a
safe distance from vehicles ahead or
on-coming vehicles.
Operation conditions
The DSA operates when the following
conditions are all met.
The ignition i s switched ON.
The DSA is turned on.
The shift lever (manual transmission
vehicle) or the selector lever (automatic
transmission vehicle) 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 avoidance support system)
(green) is displayed.
NOTE
The objects which activate the system
are four-wheeled vehicles.
The DSA may also operate in the
presence of motorcycles and bicycles.
The DSA may not operate normally
when the speed of a vehicle ahead is too
slow.
The system does not operate with the
following objects.
Vehicles approaching in the opposite
direction.
Stationary objects (stopped vehicles,
obstructions)
The DSA can be set to inoperable.
(If only the DSA is turned off)
Refer to the Settings section in the
Mazda Connect Owner's Manual.
(If the DSA is turned off by operating
the i-ACTIVSENSE switch)
Refer to i-ACTIVSENSE Switch on
page 4-85.
When the ignition is switched OFF, the
system status before it was turned off is
maintained. For example, if the ignition
is switched OFF with the DSA operable,
the system will be operable when the
ignition is switched ON the next time.

▼Vehicle Ahead Close Proximity
Wa r n i n g
When the system determines that the
distance between your vehicle and a
vehicle ahead is close, the
i-ACTIVSENSE status symbol (warning/
risk avoidance support system) changes
from green to amber and the warning
indication is displayed on the
multi-information display. While checking
the safety of the surrounding area, depress
the brake pedal while keeping a safe
distance from the vehicle ahead.
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 disp lay and a warning
sound.
Use the DAA on expressways or
highways.
Refer to Forward Sensing Camera (FSC)
on page 4-198.

Mazda Radar Cruise
Control (MRCC) (Manual
Transmission)
*
▼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.
Front radar sensor (page 4-202)
WA R N I N G
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:
 General roads other than highways
(Driving under these conditions using the
MRCC system is not possible.)
 Roads with sharp curves and where
vehicle traffic is heavy and there is
insufficient space between vehicles.
 Roads where frequent and repetitive
acceleration and deceleration occur
(Driving under these conditions using the
MRCC system is not possible).
 When 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).
