Emergency Stop SignalSystem
▼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
fl
ashes all the turn signal lights to
caution drivers behind your vehicle of
the sudden braking situation.
NOTE
Flashing
When you bring your vehicle to a
complete stop while all the turn
signal lights are flashing rapidly, the
rapid flashing of all the turn signal
lights changes back to the normal
fl ashing pattern. The turn signal lights
turn o ff when you release your foot
from the brake pedal.
Operation
When 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 turn signal
lights may flash.
The 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.
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.
Always con firm 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, or if the vehicle has
not stopped completely.
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 TCS/DSC Indication/
Indicator Light (Turns on) on page

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 7-26.
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.
You might hear the sound of a motor
when starting the EV system or
immediately after starting to drive
the vehicle. However, it does not
indicate a problem.

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)
prevents drive-wheel spinning which
occurs during acceleration from a stop
or acceleration during cornering on
slippery roads, such as wet or
snow-covered roads, and assures
optimum drive force and steerability.


The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC Indication/
Indicator Light (Turns on) on page
7-27.
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 TCS OFF
switch (page 4-65).
▼ TCS/DSC Indicator Light
When the power switch is switched
ON, the TCS/DSC indicator light turns
on and then turns
off after a few
seconds.
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
When the TCS/DSC operation
indicator light fl ashes, a sound from
the motor compartment may be
heard, however, this does not
indicate a problem. This indicates
that the TCS/DSC is operating
normally.
On slippery road surfaces, such as
freshly fallen snow, the motor
rotation speed cannot be increased
when the TCS is on.

Dynamic Stability Control(DSC)
▼Dynamic Stability Control (DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and
motor torque in conjunction with
systems such as the ABS and TCS to
help control side slip when driving on
slippery surfaces, or during sudden or
evasive steering, which enhances
vehicle stability.

Refer to ABS (page 4-63) and TCS
(page 4-64).

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
7-27.
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 Assi st (HLA) may not
operate.
Refer to Hill Launch Assist (HLA) on
page 4-61.
▼ TCS/DSC Indicator Light
When the power switch is switched
ON, the TCS/DSC indicator light turns
