Mazda Radar Cruise

Control (MRCC)

MRCC is a system that reduces load on
the driver through constant speed and
headway control. The function
performs headway control to maintain
the distance with a vehicle ahead at a
constant preset speed without you
having to depress the accelerator or
brake pedal.

Warnings and Cautions

for Using the Mazda

Radar Cruise Control

(MRCC)

WARNING

Do not rely completely on the MRCC.

The MRCC 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 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 MRCC 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.

Smart Brake Support

(SBS)

SBS is a system designed to avoid
collisions and reduce damage in the
event of a collision by controlling the
brakes. Sensors and camera equipped
on the vehicle detect objects, and
operate brake control if there is a
possibility of your vehicle colliding with
the object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.

Forward drive detection

Forward detection function

The forward detection function is
designed to assist the driver in avoiding
collisions with objects (vehicles ahead,
pedestrians, bicycles, and motorcycles)
at the front and to reduce damage in
the event of a collision.
If there is a possibility of your vehicle
colliding with a target object at the
front, you are notiﬁed of possible
danger by a screen display and a
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.
In addition, when the driver depresses
the brake pedal, the brakes are applied
ﬁrmly and quickly to assist.

Reverse drive detection

Reverse drive detection has the
following 2 functions.

Rearward detection function

The rearward detection function is
designed to assist the driver in avoiding
collisions with objects at the rear
(obstructions) and to reduce damage
in the event of a collision.
If there is a possibility of your vehicle
colliding with a target object at the
rear, you are notiﬁed of possible
danger by a screen display and a
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed to avoid
collision and reduce damage in the
event of a collision.

Rear Crossing

The Rear Crossing is designed to avoid
collision and reduce damage in the
event of a collision with a vehicle
approaching from the rear sides.
If there is a possibility of your vehicle
colliding with a vehicle approaching
from the rear sides, you are notiﬁed of
possible danger by a screen display
and a warning sound. Furthermore, if
the possibility of a collision increases,
brake control is performed to avoid
