Brake
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 Smart City Brake Support (SCBS) system is not turned off.



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.

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.

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).
