Intelligent Speed
Assistance (ISA)

▼Intelligent Speed Assistance (ISA)
The ISA is a function which keeps the
vehicle speed below the speed limit
set from a speed limit sign or an
optionally set speed limit. The speed
limit can be set between 30 and 200
km/h (19-125 mph), and if the vehicle
speed exceeds the set speed limit
while driving on steep slopes, the
system notifies the driver using the
display and a warning sound.
The ISA recognises a speed limit sign
based on the
Tra ffi c Sign Recognition
System (TSR) or the navigation system
information.
Refer to
Tra ffi c Sign Recognition
System (TSR) on page 4-111.
WARNING
Always turn
off the system when
changing drivers:
If the driver is changed and the new
driver is unaware of the ISA function,
the vehicle may not accelerate when
the driver depresses the accelerator
pedal, leading to an accident.
Depending on the weather conditions
or problems with traffic signs, a traffic
sign may not be recognised or a traffic
sign
different from the actual
traffic
sign may be displayed. Always make it
your responsibility as a driver to check
the actual traffic signs. Otherwise, it
could result in an accident.
NOTE
The ISA operates only when the
navigation system's SD card (Mazda
genuine) is inserted. In addition, the
Adjustable Speed Limiter (ASL)
operates only when the navigation
system's SD card (Mazda genuine) is
not inserted. Refer to Adjustable
Speed Limiter (ASL) on page 4-166.
The system consists of the ISA display
and the speed limiter switch on the
steering wheel.

Smart Brake Support
(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the warning indications
in the display and a warning sound if
the front radar sensor and Forward
Sensing Camera (FSC) determine that
there is the possibility of a collision
with a vehicle ahead, pedestrian, or a
bicycle. Furthermore, if 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.
(Vehicles with Driver Monitoring
(DM))
When the SBS determines that the
driver is not paying attention to the
road using the driver monitoring
camera and it determines that there is
the possibility of a collision with an
obstruction, the SBS activates the
collision warning earlier than normal.
WARNING
Do not rely completely on the
SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The ability to detect obstructions is
limited depending on the obstructions,
weather conditions, or
traffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the system
off to prevent an unexpected
operation.
¾The vehicle is being towed or when
towing another vehicle.
¾The vehicle is on a chassis roller.
¾When driving on rough roads such as
in areas of dense grass or off-road.
See the next page on how to turn
off
the system.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-177.
Operation conditions
The SBS operates when all of the
following conditions are met.
xThe ignition is switched ON. xThe SBS is on. xThe i-ACTIVSENSE warning
indication/warning light is not
turned on.
x(Object is vehicle ahead)
The vehicle speed is about 4 km/h
(2 mph) or higher.
x(Object is a pedestrian or bicycle)
The vehicle speed is between about
10 to 80 km/h (6.2 to 50 mph).
xThe DSC does not operate.
NOTE
xUnder the following conditions, the
SBS may not operate.
xIf there is the possibility of hitting
only a part of a vehicle or
obstruction ahead.
xYou are driving your vehicle at the
same speed as the vehicle ahead.
xWhen the driver deliberately
performs driving operations
(accelerator operation, steering
wheel operation).
