Mazda Radar Cruise
Control (MRCC) (Manual
Transmission)
*
▼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.
Front radar sensor (page 4-216)
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:
 General roads other than highways
(Driving under these conditions
using the MRCC 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 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.)

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 pressed 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 DSC has operated.The Smart Brake Support (SBS) has operated.When traveling on a downslope for a long period of time.There is a problem with the system.The vehicle speed decreases to less than 25 km (16 mph).The shift lever is shifted to neutra l (N) for a certain period of time.The clutch is depressed for a certain period of time.The engine stalls.The front radar sensor cannot detect target objects (during rain, fog, snow or other
inclement weather conditions, or when the radiator grille is dirty).
The parking brake is applied.Any of the doors is opened.The driver's seat belt is unfastened.The operation frequency of the brak ing by the MRCC control is high.

▼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 Down 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 Stop & 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, 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.

Also refer to the following before using
the MRCC with Stop & Go function.
AUTOHOLD (page 4-82)Forward Sensing Camera (FSC) (page
4-212)
Front radar sensor (page 4-216)
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
hitting the vehicle ahead if the vehicle
ahead applies the brakes suddenly or
another vehicle cuts into the driving
lane in front of you, 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.

inclement weather conditions, or when the radiator grille is dirty).
The parking brake is applied.Any of the doors is opened.The driver's seat belt is unfastened.The operation frequency of the braking by the MRCC with Stop & Go function
control is high.
Resuming control
If the MRCC with Stop & Go function system is canceled, you can resume control at
the previously set speed by pressing the RES switch and after all of the operation
conditions have been met.
NOTE
If the set speed is not indicated in the display, the control does not resume even if
the RES switch is pressed.
