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,
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:
General roads other than highways
(Driving under these conditions using the
MRCC with Stop & Go function system is
not possible.)
Roads 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 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).
 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,
your vehicle may slide while stopped by
the stop hold control, and it may
accelerate suddenly after it starts
moving.)
 Two-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
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.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
