Mazda Radar Cruise
Control (MRCC)
*
▼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.
xFront radar sensor (page 4-220)
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:
¾General roads other than highways
(Driving under these conditions
using the MRCC system is not
possible.)
¾Roads 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).
¾When 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).
¾Slippery roads such as ice or
snow-bound roads (Tyres could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
¾Long , descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
¾Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly.)
¾Two-wheeled vehicles such as
motorcycles or bicycles are ahead.

conditions, or when the radiator
grille is dirty).
xThe parking brake is applied.xAny of the doors is opened.xThe driver's seat belt is unfastened.xThe operation frequency of the
braking by the MRCC control is high.
Resuming control
If the MRCC system is cancelled, you
can resume control at the previously
set speed by pressing the RES switch
and after all of the operation
conditions have been met.
NOTE
If the set speed is not indicated in the
display, the control does not resume
even if the RES switch is pressed.
Turning off the system
When the MRCC switch is pressed
while the MRCC is operating, the
MRCC turns off.
▼Shift-up/Shift-down Request
Display (Manual Transmission)
The shift-up or shift-down request
display might be displayed while the
MRCC is operating. When this occurs,
shift gears because the gear position is
not appropriate.
Request Indication on display
Shift up Shift Up to a Higher Gear
Shift down Shift Down to a Lower Gear
NOTE
xIf the gears are not shifted up even
though the shift-up request
indication is displayed, load will be
applied to the engine and the MRCC
might be automatically cancelled or
engine damage could occur.
xIf the gears are not shifted down
even though the shift-down request
indication is displayed, the MRCC
might be automatically cancelled or
engine stalling could occur.

*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

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.
If the vehicle ahead stops while you are
following behind it, your vehicle will
stop and be held stopped
automatically (stop hold control), and
headway control will resume when you
resume driving the vehicle such as by
pressing the RES switch.

WARNING
Do not rely completely on the MRCC
with Stop & Go function:
The MRCC with Stop & Go function
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 in front of you, 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 with Stop & Go
function system in the following
locations. Using the MRCC with Stop
& Go function system at the following
locations may result in an unexpected
accident:
¾General roads other than highways
(Driving under these conditions
using the MRCC with Stop & Go

operates, the MRCC with Stop & Go
function indicator light turns on.
NOTE
xIf the MRCC with Stop & Go
function system is cancelled during
stop hold control, the vehicle is held
in its stopped position.
xThe parking brake is automatically
applied and the vehicle is held in its
stopped position when 10 minutes
have elapsed since the stop hold
control operated. At this time, the

system is cancelled.
xIf the i-stop operation conditions are
met during stop hold control, the
engine stops even though the brake
pedal is not depressed.

Smart Brake Support
(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the warning indications
in the display and a warning sound if
the front radar sensor and Forward
Sensing Camera (FSC) determine that
there is the possibility of a collision
with a vehicle ahead, pedestrian, or a
bicycle. Furthermore, if a collision is
unavoidable, the automatic brake
control is performed to 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.
(Vehicles with Driver Monitoring
(DM))
When the SBS determines that the
driver is not paying attention to the
road using the driver monitoring
camera and it determines that there is
the possibility of a collision with an
obstruction, the SBS activates the
collision warning earlier than normal.
WARNING
Do not rely completely on the
SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The ability to detect obstructions is
limited depending on the obstructions,
weather conditions, or
traffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the system
off to prevent an unexpected
operation.
¾The vehicle is being towed or when
towing another vehicle.
¾The vehicle is on a chassis roller.
¾When driving on rough roads such as
in areas of dense grass or off-road.
See the next page on how to turn
off
the system.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-177.
Operation conditions
The SBS operates when all of the
following conditions are met.
xThe ignition is switched ON.xThe SBS is on.xThe i-ACTIVSENSE warning
indication/warning light is not
turned on.
x(Object is vehicle ahead)
The vehicle speed is about 4 km/h
(2 mph) or higher.
x(Object is a pedestrian or bicycle)
The vehicle speed is between about
10 to 80 km/h (6.2 to 50 mph).
xThe DSC does not operate.
NOTE
xUnder the following conditions, the
SBS may not operate.
xIf there is the possibility of hitting
only a part of a vehicle or
obstruction ahead.
xYou are driving your vehicle at the
same speed as the vehicle ahead.
xWhen the driver deliberately
performs driving operations
(accelerator operation, steering
wheel operation).
