Brake
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.

Deactivating The Smart City
Brake Support (SCBS) System
Operation
The Smart City Brake Support (SCBS)
system can be deactivated.
Refer to Personalization Features on
page 9-12 .
When the Smart City Brake Support
(SCBS) system is turned off, the Smart
City Brake Support (SCBS) OFF indicator
light turns on.
NOTE
When the DSC OFF switch is pressed to
stop the DSC operation, the Smart City
Brake Support (SCBS) system operation
also stops and the Smart City Brake
Support (SCBS) OFF indicator light turns
on.

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.

4–81
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.

When Driving
ABS/TCS/DSC
DSC OFF Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the DSC OFF
switch is pressed and TCS/DSC is
switched off.
Refer to DSC OFF Switch on page 4-82 .
If the light remains illuminated and the
TCS/DSC is not switched off, take your
vehicle to an Authorized Mazda Dealer.
The DSC may have a malfunction.
DSC 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.
NOTE
 


y When DSC is on and you attempt to free
the vehicle when it is stuck, or drive
it out of freshly fallen snow, the TCS
(part of the DSC system) will activate.
Depressing the accelerator will not
increase engine power and freeing
the vehicle may be diffi cult. When this
happens, turn off the TCS/DSC.
 


y If the TCS/DSC is off when the engine
is turned off, it automatically activates
when the ignition is switched ON.
 


y Leaving the TCS/DSC on will provide
the best traction.
 


y If the DSC OFF switch is pressed and
held for 10 seconds or more, the DSC
OFF switch malfunction detection
function operates and the DSC system
activates automatically. The DSC OFF
indicator light turns off while the DSC
system is operative.

i-ELOOP
i-ELOOP *
On conventional vehicles, the kinetic energy that is generated when the vehicle is
decelerated by applying the brakes or during engine braking ends up being discarded as
heat. By utilizing this discarded kinetic energy to generate electricity and use it to power the
vehicle's electrical devices and accessories such as the A/C and audio, fuel consumption can
be reduced. Mazda's system for generating electricity from this kinetic energy is called the
Regenerative Braking System (i-ELOOP).
