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 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 15 km/h (9.3 mph).
In addition, when the driver depresses the brake pedal while the system is in the operation
range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied fi rmly and quickly to
assist. (Brake Assist (SCBS brake assist))
Laser sensor
WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safe
driving:
The Smart City Brake Support (SCBS) system cannot compensate for unsafe and reckless
driving, excessive speed, tailgating (following another vehicle too closely), and driving on
slippery roads such as wet, snowy, and icy roads (reduced tire friction and road contact
because of water on the road surface). You can still have an accident.

When Driving
Brake
Do not rely completely on the Smart City Brake Support (SCBS) system:
¾ The Smart City Brake Support (SCBS) system is only designed to reduce damage 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.
¾ The Smart City Brake Support (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.
¾ The laser sensor for the Smart City Brake Support (SCBS) system is installed near the
rearview mirror. To assure the correct operation of the Smart City Brake Support
(SCBS), heed the following cautions.
¾
Do not apply stickers to the surface of the windshield near the laser sensor
(including transparent stickers). Otherwise, the laser sensor may not be able to
detect vehicles or obstructions ahead which could result in an accident.
¾
Do not disassemble the laser sensor.
¾
If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor,
stop using the Smart City Brake Support (SCBS) system immediately and have your
vehicle inspected by an Authorized Mazda Dealer. If the vehicle continues to be
driven with cracks or scratch marks left on the windshield near the laser sensor, the
system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page
4-78 .
¾
When replacing the windshield wipers or windshield, consult an Authorized Mazda
Dealer.
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles or obstructions ahead. This will result in the Smart City Brake Support
(SCBS) system not operating normally or mistakenly operating, which could cause a
serious accident.
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation when
the vehicle is running on a chassis roller or being towed. See the next page on how to turn
off the Smart City Brake Support (SCBS).
Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page 4-78 .

CAUTION
¾ When driving off -road in areas where there is grass or forage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off .
¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
¾ The laser sensor includes a function for detecting a soiled windshield and informing the
driver, however, depending on the conditions, it may not detect plastic shopping bags, ice
or snow on the windshield. In such cases, the system cannot accurately determine a vehicle
or obstruction ahead and may not be able to operate normally. Always drive carefully and
pay attention to the road ahead.
NOTE
y The Smart City Brake Support (SCBS) system will operate under the following
conditions.
y The engine is running.
y The Smart City Brake Support (SCBS) indicator light does not illuminate.
y The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).

y The DSC operation is not turned off using the DSC OFF switch.
y The DSC is not malfunctioning.
y The driver is not deliberately performing driving operations (accelerator pedal,
steering wheel, and braking operations).
y The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam refl ected off the refl ector 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:
y Refl ection of the laser is poor due to the shape of the vehicle ahead.
y The vehicle ahead is signifi cantly dirty.
y Under bad weather condition, such as rain, fog and snow.
y The window washer is being used or the windshield wipers are not used when it's
raining.
y The windshield is dirty.
y The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
y Trucks with low loading platforms, vehicles traveling at extremely low speeds, and
vehicles with a high profi le.
y Vehicles with certain shapes such as a vehicle carrier.

Laser Sensor Handling
The Smart City Brake Support (SCBS) laser sensor is installed at the top of the windshield
near the rearview mirror.
Always keep the surface of the windshield around the laser sensor clean to assure proper
operation of the Smart City Brake Support (SCBS) system.
WARNING
As there is the possibility of eye damage occurring from the laser, always heed the
following precautions:
¾ Never remove the sensor.
¾ A removed sensor will not meet the conditions for a class 1M laser under the IEC
60825-1 specifi cation and therefore eye safety cannot be assured.
¾ Do not peer into the sensor using optical instruments with a magnifi cation function
such as magnifying glasses, and microscopic and objective lenses within a distance of
100 mm (3.94 in) from the sensor.

When Driving
ABS/TCS/DSC
Antilock Brake System
(ABS)
The ABS control unit continuously
monitors the speed of each wheel. If
one wheel is about to lock up, the ABS
responds by automatically releasing and
reapplying that wheel's brake.
The driver will feel a slight vibration in
the brake pedal and may hear a chattering
noise from the brake system. This is
normal ABS system operation. Continue to
depress the brake pedal without pumping
the brakes.
The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-22 .
WARNING
Do not rely on ABS as a substitute for
safe driving:
The ABS cannot compensate for unsafe
and reckless driving, excessive speed,
tailgating (following another vehicle
too closely), driving on ice and snow,
and hydroplaning (reduced tire friction
and road contact because of water on
the road surface). You can still have an
accident.
NOTE
y Braking distances may be longer on
loose surfaces (snow or gravel, for
example) which usually have a hard
foundation. A vehicle with a normal
braking system may require less
distance to stop under these conditions
because the tires will build up a wedge
of surface layer when the wheels skid.
y The sound of the ABS operating may
be heard when starting the engine
or immediately after starting the
vehicle, however, it does not indicate a
malfunction.

When Driving
ABS/TCS/DSC
Traction Control System
(TCS)
The Traction Control System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.
This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.
The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-22 .
WARNING
Do not rely on the Traction Control
System (TCS) as a substitute for safe
driving:
The Traction Control System ( TCS)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident.
Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow:
Driving without proper traction devices
on snow and/or ice-covered roads
is dangerous. The Traction Control
System ( TCS) alone cannot provide
adequate traction and you could still
have an accident.
NOTE
To turn off the TCS, press the DSC OFF
switch (page 4-82 ).
TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light fl ashes.
If the light stays on, the TCS, DSC
or the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
y In addition to the indicator light
fl ashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
y On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

When Driving
ABS/TCS/DSC
Dynamic Stability Control
(DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.
Refer to ABS (page 4-79 ) and TCS (page
4-80 ).
DSC operation is possible at speeds
greater than 20 km/h (12 mph).
The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-22 .
WARNING
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident.
CAUTION
¾ The DSC may not operate correctly
unless the following are observed:
¾ Use tires of the correct size specifi ed
for your Mazda on all four wheels.
¾ Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
¾ Do not mix worn tires.
¾ The DSC may not operate correctly when
tire chains are used or a temporary
spare tire is installed because the tire
diameter changes.
TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light fl ashes.
If the light stays on, the TCS, DSC
or the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
