▼Excessive Speed Warning
If the vehicle speed exceeds the speed limit sign displayed in the active driving
display/instrument cluster, the area around
the speed limit sign flashes in amber and
the warning sound is activated at the same time. If the vehicle speed continues 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.
1. Vehicle is doing 55 mph when 50 mph speed limit sign is recognized.
2. Vehicle continues to do 55 mph after 50 mph speed limit sign is recognized.

Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintaining 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.
WARNING
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 is 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 av oidance 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.
If the ignition is switched OFF while
you have canceled the system using
the i-ACTIVSENSE switch, the system
is automatically enabled the next
time the ignition is switched ON.
However, if the system is canceled
using the personalization features,
the system is not automatically
enabled.

▼Vehicle Ahead Close Proximity
Warning
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 display and a
warning sound.
Use the DAA on expressways or
highways.

(FSC) on page 4-190.

In the following cases, it may bedifficult to view the illumination/
flashing of the Blind Spot Monitoring
(BSM) warning indicator lights
equipped on the door mirrors.
Snow or ice adheres to the door
mirrors.
The front door glass is fogged or
covered in snow, frost or dirt.
Turn off the RCTA system while
pulling a trailer or while an accessory
such as a bicycle carrier is installed to
the rear of the vehicle. Otherwise,
the radio waves emitted by the radar
will be blocked causing the system to
not operate normally.
The rear side radar sensor of the
RCTA may be regulated under the
radio wave related laws of the
country where the vehicle is driven. If
this system is used abroad, it may be
necessary to turn off the system.
Refer to Rear Side Radar Sensor on
page 4-197.
▼ Canceling Operation of Rear Cross
Tra ffi c
Alert (RCTA)
The RCTA can be set to inoperable.
(If only the RCTA is turned off)
Refer to the Settings section in the
Mazda Connect Owner's Manual.
(If the RCTA is turned off by
operating the i-ACTIVSENSE switch)
Refer to i-ACTIVSENSE Switch on
page 4-85.
NOTE
If the ignition is switched OFF while
you have canceled the system using the
i-ACTIVSENSE switch, the system is
automatically enabled the next time
the ignition is switched ON. However,
if the system is canceled using the
personalization features, the system is
not automatically enabled.
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.

CX-30_8HG6-EA-19I_Edition1_new 2019-6-13 18:45:11

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:
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 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).
 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).
Slippery roads such as ice or
snow-bound 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.)
 Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
For safety purposes, switch the MRCC
system off when it is not being used.
Leaving the MRCC system turned on
when it is not in use is dangerous as it
could operate unexpectedly, resulting
in an accident.
CAUTION
 Turn the system
off when the vehicle
is running on a chassis roller.
 If your vehicle is towed or you are
towing something, switch the MRCC
system off to prevent an unexpected
operation.
NOTE
The MRCC system does not detect
the following as physical objects.
Vehicles approaching in the
opposite direction
Pe de st r ia nsStationary objects (stopped
vehicles, obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system
may not detect it correctly.
