System
▼Emergency Stop Signal System
If you apply the brakes suddenly while
driving at a speed of about 55 km/h
(34 mph) or faster, the emergency stop
signal system automatically and rapidly
flashes all the direction indicator lights
to caution drivers behind your vehicle
of the sudden braking situation.
NOTE
xFlashing
When you bring your vehicle to a
complete stop while all the direction
indicator lights are flashing rapidly,
the rapid
flashing of all the direction
indicator lights changes back to the
normal flashing pattern. The
direction indicator lights turn off
when you release your foot from the
brake pedal.
xOperation
xWhen the ABS operates, the
emergency stop signal system is
more likely to operate. Therefore, if
the brake pedal is depressed on a
slippery road, all of the direction
indicator lights may
flash.
xThe emergency stop signal system
does not operate when the hazard
warning light switch is pressed.

Hill Launch Assist (HLA)
▼Hill Launch Assist (HLA)
The HLA functions to assist in
accelerating the vehicle from a stop on
slopes. When releasing the brake pedal
and depressing the accelerator pedal
to accelerate the vehicle from a stop
while on a slope, the function prevents
the vehicle from rolling. The HLA also
operates when reversing on a slope.
The braking force is maintained
automatically after releasing the brake
pedal on a steep slope.
For manual transmission vehicles, the
HLA operates when the vehicle is tilted
rearward with the shift lever in a
forward gear, and operates when the
vehicle is tilted forward with the shift
lever in the R position.
For automatic transmission vehicles,
the HLA operates when the vehicle is
tilted rearward with the selector lever
in a forward gear, and operates when
the vehicle is tilted forward with the
selector lever in the R position.
WARNING
Do not rely completely on
HLA:
HLA is an auxiliary device for
accelerating from a stop on a slope.
The system only operates for about 2
seconds and therefore, relying only on
the system, when accelerating from a
stop is dangerous because the vehicle
may move (roll) unexpectedly and
cause an accident.
The vehicle could roll depending on
the vehicle's load or if it is towing
something. In addition, for vehicles
with a manual transmission, the
vehicle could still roll depending on
how the clutch pedal or the accelerator
pedal is operated.
Always confirm the safety around the
vehicle before starting to drive the
vehicle.
NOTE
xHLA does not operate on a gentle
slope. In addition, the gradient of
the slope on which the system will
operate changes depending on the
vehicle's load.
xHLA does not operate if the parking
brake is applied, the vehicle has not
stopped completely, or the clutch
pedal is released.
xWhile HLA is operating, the brake
pedal may feel stiff and vibrate,
however, this does not indicate a
malfunction.
xHLA does not operate while the
TCS/DSC indicator light is
illuminated.
Refer to TCS/DSC Indication/
Indicator Light (Turns on) on page
7-55.
xHLA does not turn off even if the TCS
OFF switch is pressed to turn
off the
TCS.
x(Automatic Transmission)
Although the HLA does not operate
during idling stop, the vehicle roll
prevention function operates to
prevent vehicle roll.

Antilock Brake System
(ABS)
▼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 ABS Warning Indication/
Warning Light on page 7-52.
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 tyre friction
and road contact because of water on
the road surface). You can still have an
accident.
NOTE
xBraking 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 tyres will
build up a wedge of surface layer
when the wheels skid.
xThe 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.

Traction Control System
(TCS)
▼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 TCS/DSC Indication/
Indicator Light (Turns on) on page
7-55.
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 tyre friction and road contact
because of water on the road surface).
You can still have an accident.
Use snow tyres or tyre 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 TCS 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 flashes.

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
expert repairer (we recommend an
Authorised Mazda Repairer).
NOTE
xIn addition to the indicator light
flashing, a slight labouring sound will
come from the engine. This indicates
that the TCS/DSC is operating
properly.
xOn slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

Dynamic Stability Control
(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 manoeuvring, enhancing
vehicle safety.

Refer to ABS (page 4-80) and TCS
(page 4-81).

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 TCS/DSC Indication/
Indicator Light (Turns on) on page
7-55.
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 tyre friction and road contact
because of water on the road surface).
You can still have an accident.
CAUTION
¾The DSC may not operate correctly
unless the following are observed:
¾Use tyres of the correct size
specified for your Mazda on all 4
wheels.
¾Use tyres of the same
manufacturer, brand and tread
pattern on all 4 wheels.
¾Do not mix worn tyres.
¾The DSC may not operate correctly
when tyre chains are used or a
temporary spare tyre is installed
because the tyre diameter changes.
NOTE
If there is a problem with the DSC, the
Hill Launch Assist (HLA) may not
operate.
Refer to Hill Launch Assist (HLA) on
page 4-79.
▼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 flashes.

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
expert repairer (we recommend an
Authorised Mazda Repairer).
