When Driving
Brake
WARNING
Do not rely completely on Hill Launch
Assist (HLA):
Hill Launch Assist (HLA) is an
auxiliary device for accelerating from
a stop on a slope. The system only
operates for about two 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 confi rm the safety around the
vehicle before starting to drive the
vehicle.
NOTE
  Hill Launch Assist (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.
  Hill Launch Assist (HLA) does
not operate if the parking brake is
applied, the vehicle has not stopped
completely, or the clutch pedal is
released.
  While Hill Launch Assist (HLA) is
operating, the brake pedal may feel
stiff and vibrate, however, this does
not indicate a malfunction.
  Hill Launch Assist (HLA) does not
operate while the TCS/DSC indicator
light is illuminated.
 Refer to Warning/Indicator Lights on
page 4-40 .
  Hill Launch Assist (HLA) does
not turn off even if the DSC OFF
switchis pressed to turn off the TCS/
DSC.
  (Automatic Transaxle)  Although the Hill Launch Assist
(HLA) does not operate during idling
stop, the vehicle roll prevention
function operates to prevent vehicle
roll.

When Driving
ABS/TCS/DSC
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 Warning Lights on page 4-41 .
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 tyre 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 tyres 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.

When Driving
ABS/TCS/DSC
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 Warning Lights on page 4-41 .
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
tyre friction and road contact because
of water on the road surface). You can
still have an accident.
Use snow tyres or tyre 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 DSC OFF
switch (page 4-90 ).
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 fl ashes.
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 expert
repairer, we recommend an Authorised
Mazda Repairer.
NOTE
  In addition to the indicator light
fl ashing, a slight labouring 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.

*Some models.4–89
When Driving
ABS/TCS/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 manoeuvring,
enhancing vehicle safety.
Refer to ABS (page 4-87 ) and TCS (page
4-88 ).
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 Warning Lights on page 4-41 .
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
tyre 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 tyres of the correct size
specifi ed for your Mazda on all
four wheels.
 


 Use tyres of the same
manufacturer, brand and tread
pattern on all four wheels.
 


 Do not mix worn tyres. 

 The DSC may not operate correctly
when tyre chains are used or a
temporary spare tyre is installed
because the tyre diameter changes.
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 fl ashes.
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 expert
repairer, we recommend an Authorised
Mazda Repairer.

When Driving
i-ELOOP
i-ELOOP *
On conventional vehicles, the kinetic energy that is generated when the vehicle is
decelerated by applying the brakes or during engine braking ends up being discarded as
heat. By utilizing this discarded kinetic energy to generate electricity and use it to power the
vehicle's electrical devices and accessories such as the A/C and audio, fuel consumption can
be reduced. Mazda's system for generating electricity from this kinetic energy is called the
Regenerative Braking System (i-ELOOP).

High Beam Control System (HBC) *
The High Beam Control System (HBC) determines the conditions in front of the vehicle
using the Forward Sensing Camera (FSC) while driving in darkness to automatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-40 .
While driving the vehicle at a speed of about 30 km/h (18 mph), the headlights are switched
to high beams when there are no vehicles ahead or approaching in the opposite direction.
The system switches the headlights to low beams when one of the following occurs:
 


 The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction.
 


 The vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and
towns.
 


 The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC) The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
