Slippery roads such as ice or
snow-bound roads (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
Long, descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly.)
Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
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
Turn the system off when the vehicle
is running on a chassis roller.
If your vehicle is towed or you are
towing something, switch the MRCC
system off to prevent an unexpected
operation.
NOTE
The MRCC 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.
Do not use the MRCC 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 system is in use, it

does not cancel even if the shift lever
is operated and any intended engine
braking will not occur. If deceleration
is required, lower the vehicle speed
setting or depress the brake pedal.
While braking by the MRCC 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 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.

Mazda Connect Owner's Manual.
