Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is ab out 30 km/h (19 mph) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is appropriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the active
driving display is indicated to advise you to keep a safe distance from the vehicle ahead.
WA R N I N G
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limited depending on th e type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming vehicles.

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 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 an d 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 follo wing 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 usin g the MRCC with Stop & Go function.
ï‚·AUTOHOLD (page 4-101)
ï‚·Forward Sensing Camera (FSC) (page 4-207)

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 weat her 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 sudd enly 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 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 highways (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.

When the SCBS system is turned off, the
Smart City Brake Support (SCBS) OFF
indicator light turns on.

When the engine is restarted, the system
becomes operational.
NOTE
When the SCBS system is set to
inoperable, the Smart Brake Support
(SBS) are also set to inoperable.
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 sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is performed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, 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 event 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 pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.
