Radar Sensorí
Your vehicle is equipped with a radar sensor.
The following systems also use the radar sensor.
lMazda Radar Cruise Control (MRCC)lForward Obstruction Warning (FOW)
The radar sensor functions by detecting the radio waves reflected off a vehicle ahead or an
obstruction sent from the radar sensor.
The radar sensor is mounted behind the front emblem.

If“Radar blocked”is displayed in the multi-display of the instrument cluster, clean the area
around the radar sensor.

qDisplay Indication
For 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.
qWarning Light
A system malfunction or operation
conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page
4-23.
qBrake Pad Wear Indicator
When the disc brake pads become worn,
the built-in wear indicators contact the
disc plates. This causes a screeching noise
to warn that the pads should be replaced.
When you hear this noise, consult an
Authorized Mazda Dealer as soon as
possible.
WARNING
Do not drive with worn disc pads:
Driving with worn disc pads is
dangerous. The brakes could fail and
cause a serious accident. As soon as
you hear a screeching noise consult
an Authorized Mazda Dealer.
qBrake Assist
During emergency braking situations
when it is necessary to depress the brake
pedal with greater force, the brake assist
system provides braking assistance, thus
enhancing braking performance.
When the brake pedal is depressed hard or
depressed more quickly, the brakes apply
more firmly.
NOTE
lWhen the brake pedal is depressed hard or
depressed more quickly, the pedal will feel
softer but the brakes will apply more firmly.
This is a normal effect of the brake assist
operation and does not indicate a
malfunction.
lWhen the brake pedal is depressed hard or
depressed more quickly, a motor/pump
operation noise may be heard. This is a
normal effect of the brake assist and does
not indicate a malfunction.
lThe brake assist equipment does not
supersede the functionality of the vehicle's
main braking system.

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.
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.

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
normally.
lHeavy luggage is loaded in the luggage compartment or on the rear seat.lIf there is the possibility of partial contact with a vehicle ahead.lWhen driving on continuously curving roads, and entering and exiting exits.lElongated luggage or cargo is loaded onto installed roof rails and covers the laser sensor.lExhaust gas from the vehicle in front, sand, snow, and water vapor rising from manholes and
grating, and water splashed into the air.
lWhen towing a malfunctioning vehicle.lIn the following cases, the laser sensor may inadvertently determine that there is a vehicle ahead
and the Smart City Brake Support (SCBS) system may operate.
lObjects on the road at the entrance to a curve.lVehicles passing in the opposite lane while making a curve.lMetal objects, bumps, or protruding objects on the road.lWhen passing through a toll gate.lWhen passing under a vinyl curtain or flag.lPlastic objects such as pylons.lTwo-wheeled vehicles, pedestrians, animals or standing trees.lVehicle is driven with some of the tires having significant wear.

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 4-92) and TCS (page
4-93).
DSC operation is possible at speeds
greater than 20 km/h (12 mph).
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 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
ØThe DSC may not operate correctly
unless the following are observed:
ØUse tires of the correct size
specified for your Mazda on all
four wheels.
ØUse tires of the same
manufacturer, brand and tread
pattern on all four wheels.
ØDo not mix worn tires.
ØThe DSC may not operate correctly
when tire chains are used or a
temporary spare tire is installed
because the tire diameter changes.
qDSC OFF Switch
Press the DSC OFF switch to turn off the
TCS/DSC. The DSC OFF indicator light
in the instrument cluster will illuminate.
Press the switch again to turn the TCS/
DSC back on. The DSC OFF indicator
light will turn off.

vibrates, consult an Authorized Mazda
Dealer.

cluster, check the vehicle condition or
have the vehicle inspected at an
Authorized Mazda Dealer according to
