instrument cluster is turned on), the
message Brake Pedal Must Be
Depressed to Deactivate Auto Hold
System is indicated on the
multi-information display to notify the
driver to depress the brake pedal.
(Type C instrument cluster)
If the AUTOHOLD switch is pressed
without depressing the brake pedal

(Green)
If any of the following conditions occurs
while the AUTOHOLD function is
operating (AUTOHOLD active indicator
light is turned on), the parking brake is
applied automatically and the
AUTOHOLD function turns off. For the
Electric Parking Brake (EPB)
operation, refer to the Electric Parking
Brake (EPB) on page 4-96.
The ignition is switched OFF.
There is a problem with the
AUTOHOLD function.
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 function prevents the
vehicle from rolling. The braking force is
maintained automatical ly after the brake
pedal is released on a steep grade.
For vehicles with a manual transaxle,
HLA operates on a downward slope when
the shift lever is in the reverse (R)
position, and on an upward slope when the
shift lever is in a po sition other than the
reverse (R) position.
For vehicles with an automatic transaxle,
HLA operates on a downward slope when
the selector lever is 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. In
addition, for vehicles with a manual
transaxle, 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
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.
HLA does not operate if the parking
brake is applied, the vehicle has not
stopped completely, or the clutch pedal
is released.
While HLA is operating, the brake pedal
may feel stiff and vibrate, however, this
does not indicate a malfunction.
HLA does not operate while the
TCS/DSC indicator light is illuminated.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-27.
HLA does not turn off even if the TCS
OFF switch is pressed to turn off the
TCS.

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-27.
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 automa tically 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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-27.
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
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 4-108).
▼ 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
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.

Dynamic Stability Control(DSC)
The Dynamic Stabil ity 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 4-106) and TCS (page
4-107).

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-27.

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.
