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 radar sensor (front) to detect
the distance to the vehicle ahead and a preset vehicle speed wi thout 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 headway con trol will resume when you
resume driving the vehicle such as by pressing the RES switch.
Also refer to the following befo re using the MRCC with Stop & G o function.
•Forward Sensing Camera (FSC) (page 4-145)
•Radar sensor (front) (page 4-150)
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 dece lerate sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the brakes sudd enly or another vehicle cuts into the driving
lane, which could result in an accident.
Always drive carefully and verify the surroundi ng conditions and depress the brake pedal or
accelerator pedal while keeping a safer 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 high ways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)
Roads with sharp curves and where vehicle tr affic is heavy and there is insufficient space
between vehicles.
Roads where frequent and repetitive accelerati on and deceleration occur (Driving under
these conditions using the MRCC with Stop & Go function system is not possible).

vehicle is held in its stopped position. The stop hold control can be canceled by
performing one the following actions.
•Press the accelerator pedal and resume driving the vehicle.
•While forcefully depressing the brake, switch the MRCC with Stop & Go function
system off.
•The electric parking brake (EPB) 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 canceled.
•The brake lights turn on during stop hold control.
To resume driving
After the vehicle ahead starts moving while your vehicle is sto pped under stop hold control,
press the RES switch or depress the accelerator pedal to cancel the stop hold control and
resume driving.
NOTE
•When you resume driving by pressing the RES switch, your vehicle does not start moving
until the distance between your vehicle and the vehicle ahead lengthens to the specified
distance or farther.
•If the MRCC with Stop & Go function is temporarily canceled during stop hold control,
you cannot resume driving by pressing the RES switch when there are no vehicles in front
of your vehicle. Depress the accelerator pedal and resume driving the vehicle.

lever is returned and the system detects white (yellow) lane lines while the vehicle is being
driven normally within its vehicle lane.
•If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white (yellow) line, the system determines that the driver is
making a lane change and the LAS&LDWS operation is temporarily canceled. The
LAS&LDWS becomes operational again when the system detects white (yellow) lane lines
while the vehicle is being driven normally within its vehicle lane.
•If the vehicle deviates from its lane repe atedly within a short period of time, the
LAS&LDWS may not operate.
•When white (yellow) lane lines are not detected, the LAS&LDWS does not operate.

Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detec ts a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the bra ke control (Smart City Brake
Support (SCBS) brake) when the system determines that a collisi on is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/ h (2 to 18 mph). It may also
be possible to avoid a collision if the relative speed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is i n the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to assist. (Brake Ass ist (Smart City Brake Support
(SCBS) brake assist))

WA R N I N G
Do not rely completely on the SCBS system:
The SCBS system is only designed to reduce da mage in the event of a collision. Over reliance
on the system leading to the accelerator pedal or brake pedal being mistakenly operated
could result in an accident.
The SCBS is a system which operates in response to a vehicle ahead. The system may not be
able to detect or react to 2-wheeled vehicles or pedestrians.

Smart Brake Support (SBS)*
The SBS system alerts the driver of a possible collision using a display and warning sound
if the radar sensor (front) and the Forward Sensing Camera (FSC ) determine that there is the
possibility of a collision with a vehicle ahead while the vehicle is being driven at about 15
km/h or faster (10 mph or faster). Furthermore, if the radar se nsor (front) and the Forward
Sensing Camera (FSC) determines that a collision is unavoidable , the automatic brake
control is performed to reduce da mage in the event of a collision.
In addition, whe n the driver depresses the brake ped al, the brakes are applied firmly and
quickly to assist. (Brake Assist (SBS brake assist))
WA R N I N G
Do not rely completely on the SBS system and always drive carefully:
The SBS is designed to reduce damage in the ev ent of a collision, not avoid an accident. The
ability to detect an obstruction is limited depending on the obstruction, weather conditions,
or traffic conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly operated
it could result in an accident. Always verify the safety of the surrounding area and depress the
brake pedal or accelerator pe dal while keeping a safer distance from vehicles ahead or
on-coming vehicles.
CAUTION
In the following cases, turn the system off to prevent a mis-operation:
The vehicle is being towed or when towing another vehicle.
The vehicle is on a chassis roller.
When driving on rough roads such as in areas of dense grass or
off-road.
NOTE
•The SBS system operates when all of the following conditions are met:
•The ignition is switched ON.
•The SBS system is on.
•The vehicle speed is about 15 km/h or faster (10 mph or faster).
•The relative speed between your vehicle and the vehicle ahead is about 15 km/h or
faster (10 mph or faster).
•The Dynamic Stability Control (DSC) is not operating.
•The SBS system may not operate under the following conditions:
•If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.
