Smart City Brake Support (SCBS)í
lThe 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 a 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 firmly and
quickly to assist. (Brake Assist (SCBS brake assist))
lFor vehicles with the type A instrument cluster, check the vehicle condition or have the
vehicle inspected at an Authorized Mazda Dealer according to the indication.
lA system malfunction or operation conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page 4-23.

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.

Do not rely completely on the Smart City Brake Support (SCBS) system:
ØThe 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.
ØThe 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.
ØThe 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.
ØDo 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 ahead which could result in an accident.
ØDo not disassemble the laser sensor.
ØIf cracks or damage caused by flying 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 4-91.
ØWhen 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 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).

CAUTION
ØWhen 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.
ØAlways use tires for all wheels that are of the specified size, and the same
manufacture, brand, and tread pattern. In addition, do not use tires with
significantly different wear patterns on the same vehicle. Do not use tires with
significantly different wear patterns on the same vehicle as the Smart City Brake
Support (SCBS) system may not operate normally.
ØThe 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 ahead and may not be able to operate
normally. Always drive carefully and pay attention to the road ahead.

NOTElThe Smart City Brake Support (SCBS) system will not operate if the driver is deliberately
performing driving operations (accelerator pedal and steering wheel).
lThe Smart City Brake Support (SCBS) system will operate under the following conditions.lThe engine is running.lThe display in the instrument cluster does not indicate that the system requires inspection or it
cannot be used.
lThe vehicle speed is between about 4 to 30 km/h (2 to 18 mph).lThe Smart City Brake Support (SCBS) system is not turned off.lThe DSC operation is not turned off using the DSC OFF switch.lThe DSC is not malfunctioning.lThe 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:
lReflection of the laser is poor due to the shape of the vehicle ahead.lThe vehicle ahead is significantly dirty.lUnder bad weather condition, such as rain, fog and snow.lThe window washer is being used or the windshield wipers are not used when it's raining.lThe windshield is dirty.lThe steering wheel is turned completely left or right, or the vehicle is accelerated rapidly and
comes close to the vehicle ahead.
lTrucks with low loading platforms and vehicles with an extremely low or high profile.lVehicles with certain shapes such as a vehicle carrier.lUnder the following conditions, the Smart City Brake Support (SCBS) system may not operate

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.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page
4-23.
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
lBraking 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.
lThe 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.
