▼Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
The MRCC with St
op & 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, y our 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 fo llowing before using

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
If your vehicle is towed or you are towing
something, switch the MRCC with Stop &
Go function system
off to prevent an
unexpected operation.
 Turn the system off when the vehicle is
running on a chassis roller.
NOTE
The MRCC with Stop & Go function
system does not detect the following as
physical objects.
Vehicles approaching in the opposite
direction
Pedestrians
Stationary objects (stopped vehicles,
obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system may not
detect it correctly.
If 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.
Do not use the MRCC with Stop & Go
function system under conditions in
which close proximity warnings are
frequently activated.
During 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.
While the MRCC with Stop & Go
function system is in use, it does not
cancel even if the selector lever is
operated and any intended engine
braking does not occur. If deceleration
is required, lower the set speed or
depress the brake pedal.
While braking by the MRCC with Stop
& Go function control is operating, you
might hear an operation sound,
however, this does not indicate a
problem.
The brake lights turn on while braking
by the MRCC with Stop & Go function
control is operating, however, they may
not turn on while the vehicle is on a
down slope at the set vehicle speed or
traveling at a constant speed and
following a vehicle ahead.
Stop the headway control function to
switch the system to the cruise control
function.
