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 7-30.
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
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.
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.

Tra c t i o n C o n t r o l Sy s te m(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
7-32.
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 t u r n o
ff the TCS, press the DSC OFF
switch (page 4-80).
▼ 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
Authorized Mazda Dealer.
NOTE
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.
On 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 maneuvering, enhancing
vehicle safety.

Refer to ABS (page 4-77) and TCS
(page 4-78).

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
7-32.
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

The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
speci fied for your Mazda on all 4
wheels.
 Use tires of the same
manufacturer, brand and tread
pattern on all 4 wheels.
 Do not mix worn tires.
 The DSC may not operate correctly
when tire chains are used or a
temporary spare tire is installed
because the tire 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 4-75.

Distance & Speed Alert(DSA)
*
▼Distance & Speed Alert (DSA)
The DSA is a system which provides
advice for maintaining the appropriate
distance between vehicles and
notifies
the driver of the recommended, safe
distance to maintain with a vehicle
ahead. The system measures the
distance between your vehicle and a
vehicle ahead while the vehicle speed
is about 30 km/h (19 mph) or faster. If
the distance between your vehicle and
a vehicle ahead is close, the system
alerts the driver of a possible collision
using an indication on the display.
WARNING
Do not rely completely on the DSA :
The ability of the system to detect a
vehicle ahead is limited depending on
the type of vehicle ahead, weather
conditions, or tra ffic conditions. In
addition, the system is not for
maintaining the distance between your
vehicle and a vehicle ahead. If you
neglect to operate the accelerator and
brake pedals correctly, it could lead to
an accident. Always check the safety of
the surrounding area and depress the
brake pedal or accelerator pedal while
keeping a safe distance from vehicles
ahead or on-coming vehicles.
Operation conditions
