NOTE
If a vehicle ahead is detected while traveling at a constant speed, the vehicle-ahead
indication is displayed and headway control is performed. Additionally, when a vehicle
ahead is no longer detected, the vehicle-ahead indication turns off and the system
switches back to travel at constant speed.
The lowest possible speed which can be set on the MRCC system is 30 km/h (19 mph).
Headway control is not possible if the vehicle ahead is driving faster than your vehicle's
set speed. Adjust the system to the desired vehicle speed using the accelerator pedal.
How to set the distance-between- vehicles during headway control
The distance-between-vehicles can be set to 4 levels; Long, med ium, short, and extremely
short distance.

NOTE
The distance-between-vehicles differs depending on the vehicle speed, and the slower the
vehicle speed, the shorter the distance.
When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance-between-vehicles to the previous setting.
Changing the Set Vehicle Speed
To accelerate/decelerate using the RES
switch
When the RES switch is pressed up (SET
+), the vehicle accelerates and when the
RES switch is presse d down (SET-), it
decelerates.
Press and release immediately: 1 km/h
(1 mph)
Press and hold: 10 km/h (5 mph)
To increase speed using accelerator
pedal
Depress the accelerator pedal and press the
RES switch up (SET+) or down (SET-) at
the desired speed. If the switch is not
operated, the system returns to the set
speed after you release your foot from the
accelerator pedal.
NOTE
The warnings and brake control do not
operate while the accelerator pedal is
depressed.
Canceling the system
When the following operations are
performed, the MRCC system is canceled,
and the MRCC set indication (green)
switches to the MRCC standby indication
(white) at the same time.
The CANCEL switch is pressed.
The brake pedal is depressed.
The shift lever is in the reverse (R)
position.

Under the following conditions, the
MRCC cancel indication is displayed in
the multi-information display and a single
beep sound is heard.

the MRCC is operating, the MRCC turns
off.
▼ Shift-up/Shift-down Request Display
The shift-up or shift-down request display
might be displayed while the MRCC is
operating. When this occurs, shift gears
because the gear position is not
appropriate.
Request Indication on display
Shift up Shift Up to a Higher Gear
Shift down Shift Do wn to a Lower Gear
NOTE
If the gears are not shifted up even
though the shift-up request indication is
displayed, load will be applied to the
engine and the MRCC might be
automatically canceled or engine
damage could occur.
If the gears are not shifted down even
though the shift-down request indication
is displayed, the MRCC might be
automatically canceled or engine
stalling could occur.

▼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 he adway control will
resume when you resume driving the
vehicle such as by pressing the RES
switch.
Also refer to the fo llowing before using
the MRCC with Stop & Go function.

WA R N I N G
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 and there is
insufficient space between vehicles.
Roads where frequent and repetitive
acceleration and deceleration occur
(Driving under these conditions using the
MRCC with Stop & Go function system 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.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
 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.)

Mazda3_8HE9-EA-18K_Edition3 2018-11-21 14:31:58

For safety purposes, switch the MRCC with
Stop & Go function system off when it is not
being used.
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.
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.
The sound of the automatic brakes
operating may be heard, however, it
does not indicate a problem.
The brake lights turn on while the
MRCC with Stop & Go function
automatic braking is operating.
