AUTOHOLD
The AUTOHOLD function automatically holds the vehicle stopped, even if you take your
foot off the brake pedal. This function can be best used while stopped in traffic or at a traffic
light. The brakes are released when you start driving the vehic le.
WA R N I N G
Do not rely completely on the AUTOHOLD function:
The AUTOHOLD function is only designed to assist the brake operation while the vehicle is
stopped. Neglecting to operate the brakes and relying only on the AUTOHOLD system is
dangerous and could result in an unexpected a ccident if the vehicle were to suddenly move.
Operate the brakes appropriatel y in accordance with the road and surrounding conditions.
Note that the vehicle may move suddenly depending on the vehicle's load or if it is towing
something.
Do not release your foot from the brake pedal while the vehicle is stopped on a steep grade:
Because there is a possibility of the vehicle not being held in the stopped position by the
AUTOHOLD function, the vehicle may move un expectedly and result in an accident.
Do not use the AUTOHOLD function on slippery roads such as icy or snow-covered roads, or
unpaved roads:
Even if the vehicle is held in the stopped posi tion by the AUTOHOLD function, the vehicle may
move unexpectedly and result in an accident . Operate the accelerator pedal, brakes, or
steering wheel approp riately as necessary.
Immediately depress the brake pedal in the following cases:
Because the AUTOHOLD function is canceled forcibly, the vehicle may move unexpectedly
and result in an accident.
 The brake pedal operation demand warning light (red) flashes and the warning sound is
activated at the same time.

Hill Launch Assist (HLA)
HLA is a function which assists the driver
in accelerating from a stop while on a
slope. When the driver releases the brake
pedal and depresses the accelerator pedal
while on a slope, the f unction prevents the
vehicle from rolling. The braking force is
maintained automatically after the brake
pedal is released on a steep grade.
HLA operates on a downward slope when
the selector lever i s in the reverse (R)
position, and on an upward slope when the
selector lever is in a forward gear.
WA R N I N G
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.
Always confirm the safety around the
vehicle before starting to drive the vehicle.
NOTE
ï‚·HLA 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.
ï‚·HLA does not operate if the parking
brake is applied, or if the vehicle has not
stopped completely.
ï‚·HLA is operating, the brake pedal may
feel stiff and vibrate, however, this does
not indicate a malfunction.

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
ï‚·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.
ï‚·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.
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 co uld still have an
accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-92).
â–¼ 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
ï‚·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.
ï‚·On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

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 -90) and TCS (page
4-91).

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.
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
specified 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.
â–¼ TCS/DSC Indicator Light
This indicator light stays on for a few

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
4-93.
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,

 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
ï‚·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).
