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
¾Turn the system off when the vehicle
is running on a chassis roller.
¾If your vehicle is towed or you are
towing something , switch the MRCC
system off to prevent an unexpected
operation.
NOTE
xThe MRCC system does not detect
the following as physical objects.
xVehicles approaching in the
opposite direction
xPedestriansxStationary objects (stopped
vehicles, obstructions)
xIf a vehicle ahead is travelling at an
extremely low speed, the system
may not detect it correctly.
xIf there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC.
xDo not use the MRCC system under
conditions in which close proximity
warnings are frequently activated.
xDuring headway control travel, the
system accelerates and decelerates
your vehicle in conjunction with the
speed of the vehicle ahead.
However, if it is necessary to
accelerate for a lane change or if the
vehicle ahead brakes suddenly
causing you to close in on the vehicle
rapidly, accelerate using the
accelerator pedal or decelerate using
the brake pedal depending on the
conditions.
xWhile the MRCC system is in use, it
does not cancel even if the selector
lever (automatic transmission)/shift
lever (manual transmission) is
operated and any intended engine
braking will not occur. If deceleration
is required, lower the vehicle speed
setting or depress the brake pedal.
xWhile braking by the MRCC control
is operating, you might hear an
operation sound, however, this does
not indicate a problem.
xThe brake lights turn on while
braking by the MRCC control is
operating , however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or travelling at a constant speed and
following a vehicle ahead.
xStop the headway control function to
switch the system to the cruise
control function.
Refer to the Settings section in the
Mazda Connect Owner's Manual.

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
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
Mazda Radar Cruise Control
(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.
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.
Also refer to the following before using
the MRCC with Stop & Go function.

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
function 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
with Stop & Go function is not
possible).
When Driving
i-ACTIVSENSE
*Some models.4-139

Page 290 of 683

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, your vehicle may slide
while stopped by the stop hold
control, and it may accelerate
suddenly after it starts moving.)
¾Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
For safety purposes, switch the MRCC
with Stop & Go function system off
when it is not being used.
Leaving the MRCC with Stop & Go
function system turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.Do not get out of the vehicle while
the stop hold control is operating:
Getting out of the vehicle while the
stop hold control is operating is
dangerous as the vehicle may move
unexpectedly and result in an accident.
Before getting out of the vehicle,
switch the MRCC with Stop & Go
function system off, shift the selector
lever to the P position, and apply the
parking brake.
CAUTION
¾If your vehicle is towed or you are
towing something, switch the MRCC
with Stop & Go function system off
to prevent an unexpected operation.
¾Turn the system off when the vehicle
is running on a chassis roller.
NOTE
xThe MRCC with Stop & Go function
system does not detect the following
as physical objects.
xVehicles approaching in the
opposite direction
xPedestriansxStationary objects (stopped
vehicles, obstructions)
xIf a vehicle ahead is travelling at an
extremely low speed, the system may
not detect it correctly.
xIf there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC
with Stop & Go function.
xDo not use the MRCC with Stop &
Go function system under conditions
in which close proximity warnings
are frequently activated.
