Antilock Brake System(ABS)
The ABS control unit continuously
monitors the speed o f 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 brak e pedal without
pumping the brakes.

The warning light turns on when the
system has a malfunction.
Contact an Authorized Mazda Dealer and
Have Vehicle Inspected on page 7-31.
WA R N I N G
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 wi ll 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.

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.
Contact an Authorized Mazda Dealer and
Have Vehicle Inspected on page 7-31.
WA R N I N G
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

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 TCS OFF
switch (page 4-106).
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS, DSC or the Trailer Stability
Control (TSC) is ope
rating, 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
flashing, 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.

This indicator light
stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the TCS OFF
switch is pressed and TCS is switched off.
Refer to TCS OFF Switch on page 4-106.

If the light remains illuminated and the
TCS is not switched off, take your vehicle
to an Authorized Mazda Dealer. The DSC
may have a malfunction.
▼ TCS OFF Switch*
Press the TCS OFF sw
itch to turn off the
TCS. The TCS OFF indicator light in the
instrument cluster and TCS OFF switch
indicator light turn on.
Indicator light
Press the switch agai n to turn the TCS
back on. The TCS OFF indicator light and
TCS OFF switch indica tor light will turn
off.
NOTE
When TCS 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 difficult. When this
happens, turn off the TCS.
If the TCS is off when the engine is
turned off, it aut omatically activates
when the ignition is switched ON.
Leaving the TCS on will provide the best
traction.
If the TCS OFF switch is pressed and
held for 10 seconds or longer, the TCS
can no longer be turned off even if the
TCS OFF switch is pressed.
In this case, the TCS OFF switch will
operate normally when the ignition is
switched ON again after being switched
OFF.

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 4-104) and TCS (page
4-105).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Contact an Authorized Mazda Dealer and
Have Vehicle Inspected on page 7-31.

Trailer Stability Control(TSC)
If the vehicle sways while being driven
and towing a trailer, the Trailer Stability
Control (TSC) automatically controls
braking and engine torque to suppress the
swaying and enhance vehicle stability.
The Trailer Stabili ty Control (TSC) is
operable at a vehicle speed of about 65
km/h (40 mph) or more.
When the Trailer Sta bility Control (TSC)
operates while driving the vehicle, the
TCS/DSC indicator light flashes.
Refer to TCS/DSC Indicator Light on page
4-107.
WA R N I N G
Do not rely solely on the Trailer Stability
Control (TSC)
Assured vehicle stability is limited even if
the Trailer Stability Control (TSC) is
operating. Drive carefully to prevent
accidents.
In particular, if the TCS/DSC indicator light
is flashing, drive the vehicle carefully as it is
in a less stable condition and could sway
more easily. Drive with caution and in
accordance with the road, vehicle and
trailer conditions.
CAUTION
 The Trailer Stability Control (TSC) may
not operate correctly unless the
following are observed:
 Use tires of the correct size specified for
your Mazda on all four wheels.
Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 Do not mix worn tires.
 The Trailer Stability Control (TSC) may
not operate correctly when tire chains
are used or a temp orary spare tire is
installed because the tire diameter
changes.
NOTE
The Trailer Stability Control (TSC) uses
the TCS/DSC functions. The Trailer
Stability Control (TSC) does not operate
if there is a malfunction in the TCS/DSC
(the TCS/DSC indicator light turns on).
When the Trailer Stability Control (TSC)
is operating, the brake lights may turn
on.
