i-ACTIVSENSE
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver
support systems which make use of a Forward Sensing Camera (FSC) and radar
sensors.
These systems consist of active safety and pre-crash safety systems.
Driver awareness support systems
• Adaptive Front Lighting System (AFS)
• High-Beam Control system (HBC)
• Lane Departure Warning System (LDWS)
• Blind Spot Monitoring (BSM)
• Distance Recognition Support System (DRSS)
These systems are designed to assist the driver in safer driving by reducing the load
on the driver and helping to avert collisions or reduce their severity. However,
because each system has its limitations, always drive carefully and do not rely
solely on the systems.
Active Safety Technology
Active Safety Technology supports safer driving by helping the driver to recognise
potential hazards and avert accidents.
Nighttime visibility
Forward/rear detection
Inter-vehicle distance recognition
• Rear Cross Traffic Alert (RCTA)
Rear obstruction detection when leaving a parking space
• Mazda Radar Cruise Control (MRCC)
Inter-vehicle distance
• Adjustable Speed Limiter
Speed control
Collision damage reduction in low vehicle speed range
• Smart City Brake Support (SCBS)
Pre-Crash Safety Technology
Pre-crash safety technology is designed to assist the driver in averting collisions or
reduce their severity in situations where they cannot be avoided.
Forward driving
• Smart Brake Support (SBS)
Collision damage reduction in medium/high speed range

When Driving
For details, refer to Section 4, “Mazda Radar Cruise Control (MRCC)”.
Mazda Radar Cruise Control (MRCC) system
The Mazda Radar Cruise Control (MRCC) system is designed to maintain
headway control according to the vehicle speed using a radar sensor to detect the
distance to a vehicle ahead, which frees the driver from having to use the
accelerator or brake pedals.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for
example, 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.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other
highways which do not require a lot of repeated acceleration and deceleration. The possible vehicle speed setting ranges are as follows:
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system
and always drive carefully:
The Mazda Radar Cruise Control (MRCC) system has limitations in its ability to
detect vehicles ahead depending on the weather and 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.
Check the safety of the surroundings and pay sufficient attention to the
distance between your vehicle and the vehicles travelling in front and behind.
WARNING
Do not use the Mazda Radar Cruise Control (MRCC) system in the
following locations. Otherwise, it could lead to an accident:
• Roads with sharp curves, heavy traffic, or roads requiring repeated and
frequent acceleration.
• When entering expressway interchanges and service areas.
• Slippery roads such as ice or snow-bound roads.
• Long descending slopes.
• (European models)
About 30 km/h (19 mph) to 200 km/h (124 mph)
• (Except European models)
About 30 km/h (19 mph) to 145 km/h (90 mph)

The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a
near-infrared laser beam and receiving the beam reflected off the reflector of the
vehicle ahead, and then using it for the measurement. Consequently, the Smart
City Brake Support (SCBS) may not operate under the following conditions:
• Trucks with low loading platforms, vehicles travelling at extremely low
speeds, and vehicles with a high profile. Do not rely completely on the Smart City Brake Support (SCBS) system:
The Smart City Brake Support (SCBS) is a system which operates in response to a
vehicle ahead. It does not apply to two-wheeled vehicles or pedestrians.
If the vehicle height or inclination is changed, the system will not be able
to correctly detect vehicles or obstructions ahead resulting in the Smart
City Brake Support (SCBS) system not operating normally or mistakenly
operating, which could cause a serious accident.
WARNING
Do not modify the suspension:
NOTE
Smart City Brake Support (SCBS)
The Smart City Brake Support (SCBS) system is designed to reduce damage in the
event of a collision by operating the brake control (SCBS brake) when the
system's laser sensor (front) detects a vehicle ahead and determines that a collision
with the vehicle ahead is unavoidable.
It may also be possible to avoid a collision if the relative speed between your
vehicle and the vehicle ahead is less than about 20 km/h (12 mph).
For details, refer to Section 4, “Smart City Brake Support (SCBS)”.
• Under bad weather condition, such as rain, fog and snow.
• The window washer is being used or the windscreen wipers are not used
when its raining.
• The windscreen is dirty.
• The steering wheel is turned completely left or right, or the vehicle is
accelerated rapidly and comes close to the vehicle ahead.Other details are
described in the related text.

When Driving
Smart Brake Support (SBS)
Smart Brake Support (SBS) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster while the
vehicle is being driven at about 15 km/h or faster (10 mph or faster) and the
system's radar sensor (front) determines that your vehicle may hit a vehicle
ahead. Furthermore, if the radar sensor (front) determines that a collision is
unavoidable, the automatic brake control is performed to reduce damage in the
event of a collision.
For details, refer to Section 4, “Smart Brake Support (SBS)”.
Do not rely completely on the Smart Brake Support (SBS) system and always
drive carefully:
The Smart Brake Support (SBS) system is only designed to reduce damage in the
event of a collision. The ability to detect obstructions is limited depending on the
obstruction, weather conditions, or traffic conditions.
Check the safety of the surroundings and pay sufficient attention to the
distance between your vehicle and the vehicles travelling in front and behind.

Smart Brake Support (SBS)
NOTE
The Smart Brake Support (SBS) system may not operate under the followingy
conditions:
• If there is the possibility of hitting only a part of a vehicle ahead.
Although the objects which activate the system are four-wheeled vehicles, the
radar sensor could detect the following objects, determine them to be an
obstruction, and operate the Smart Brake Support (SBS) system.
• Objects on the road at the entrance to a curve (including guardrails and
snow banks).
If there is the possibility of a collision with a vehicle or
obstruction ahead, the beep sounds continuously and a
warning is indicated in the display.
Collision Warning
Other details are described in the related text.
Other details are described in the related text.
• The vehicle is driven at the same speed as the vehicle ahead.
• The brake pedal, steering wheel, selector lever, or a direction indicator is
operated.
• A vehicle appears in the opposite lane while cornering or rounding a curve.
• When crossing a narrow bridge, passing through a low gate or tunnel, a
narrow gate, or entering an underground parking area.
• Metal objects, bumps, or protruding objects on the road.
• Two-wheeled vehicles such as motorcycles and bicycles, pedestrians, trees.
