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.

*1 with a vehicle
ahead according to your vehicle's

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

locations. Using the MRCC with Stop
& Go function system at the following
locations may result in an unexpected
accident:
¾General roads other than highways

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

Flashes on page 7-49.
▼Close Proximity Warning
If your vehicle rapidly closes in on the
vehicle ahead because the vehicle
ahead applies the brakes suddenly
while you are travelling in headway
control, the warning sound activates
and the brake warning is indicated in
the display. Always verify the safety of
the surrounding area and depress the
brake pedal while keeping a safe
distance from the vehicle ahead.
Additionally, keep a safe distance from
the vehicles behind you.

not operate while the accelerator
pedal is depressed.
x(European models)
When switching to a passing lane
and operating the direction
indicator, the system provides more
acceleration automatically if it
determines that more acceleration is
required. Drive while being careful of
the road ahead because you could
approach the vehicle ahead too
closely.
Cancelling the system

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
MRCC with Stop & Go function
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.
