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.
Refer to Warning Lights on page 4-24.
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.
Refer to Warning Lights on page 4-24.
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 could still have an
accident.
NOTE
To turn off the TCS, press the DSC OFF
switch (page 4-69).
▼ 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 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 4-66) and TCS (page
4-67).

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 4-24.

CAUTION
 The DSC 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 DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.

NOTE
The timing in which the system switches the headlights changes under the following
conditions. If the system does not switch the headlights appropriately, manually switch
between high and low beams according to the visibility as well as road and traffic
conditions.
When there are sources of light in the area such as street lamps, illuminated signboards,
and traffic signals.
When there are reflective objects in the surrounding area such as reflective plates and
signs.
When visibility is reduced under rain, snow and foggy conditions.
When driving on roads with sharp turn or hilly terrain.
When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim
or not illuminated.
When there is sufficient darkness such as at dawn or dusk.
When the luggage compartment is loaded with heavy objects or the rear passenger seats
are occupied.
When visibility is reduced due to a vehicle in front of you spraying water from its tires
onto your windshield.
▼ To Operate the System
The HBC operates to sw
itch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The HBC determines t hat it is dark based
on the brightness of the surrounding area.
At the same time, th e HBC indicator light
(green) in the instrument cluster
illuminates.

The HBC determines t hat it is dark based
on the brightness of the surrounding area.
NOTE
When the vehicle speed is about 30 km/h
(19 mph) or more, the headlights
automatically switch to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
When the vehicle speed is less than
about 20 km/h (12 mph), the HBC
switches the headlights to low beams.
The low beams may not switch to high
beams when cornering.
Operation of the HBC function can be
disabled. Refer to Personalization

Stop sign
WA R N I N G
Always check the traffic signs visually while driving.
The TSR helps prevent the driver from overlooking traffic signs and provides support for safer
driving. Depending on the weather conditions or problems with traffic signs, a traffic sign may
not be recognized or a traffic sign different from the actual traffic sign may be displayed.
Always make it your responsibility as a driver to check the actual traffic signs. Otherwise, it
could result in an accident.
NOTE
The TSR does not operate if there is a malf unction in the Forward Sensing Camera (FSC).
Under the following conditions, the TSR may not operate normally.
An object placed on the dashboard is reflected in the windshield and picked up by the
camera.
Heavy luggage is loaded in the luggage compartment or on the rear seat and the
vehicle is tilted.
The tire pressures are not adjusted to the specified pressure.
Tires other than standard tires are equipped.
The vehicle is driven on the ramp and surrounding area to or from a rest area or a

Mazda Radar Cruise Control (MRCC)*
The MRCC system is designed to maintain headway control*1 with a vehicle ahead
according to your vehicle's speed using a radar sensor (front) to detect the distance to the
vehicle ahead and a preset vehicle speed without you having to use the accelerator or brake
pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the MRCC system.
Additionally, if your vehicle starts closing in on the vehicle ahead such as if the vehicle
ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
Also refer to the following before using the MRCC.
Radar sensor (front) (page 4-136)
WA R N I N G
Do not rely completely on the MRCC:
The MRCC system has detection limitations depending on the type of vehicle ahead and its
conditions, the weather conditions, and the road conditions. Additionally, the system may be
unable to decelerate sufficiently to avoid hitting the vehicle ahead if the vehicle ahead applies
the brakes suddenly or another vehicle cuts into the driving lane, which could result in an
accident.
Always drive carefully and verify the surrounding conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the following locations, using the MRCC system at the
following locations may result in an unexpected accident:
 General roads other than highways (Driving under these conditions using the MRCC system
is not possible.)
 Roads with sharp curves and where vehicle tr affic is heavy and there is insufficient space
between vehicles.
 Roads where frequent and repeti tive acceleration and deceleration occur (Driving under
these conditions using the MRCC system is not possible).
 When entering and exiting interchanges, servic e areas, and parking areas of highways (If
you exit a highway while headway control is in use, the vehicle ahead will no longer be
tracked and your vehicle may accelerate to the set speed).
 Slippery roads such as ice or snow-bound roads (Tires could sp in causing you to lose vehicle
control, or the stop hold control may not operate.)
 Long, descending slopes (to maintain distan ce between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)

engine damage could occur.
▼ Cruise Control Function
While this function is operating, the
headway control operation is canceled and
only the cruise control function operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise c
ontrol function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WA R N I N G
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
 Roads with sharp curves and where
vehicle
traffic is heavy and there is
insufficient space between vehicles.
(Driving under these conditions using the
cruise control function is not possible)
 Steep down slopes (Set speed may be
exceeded because
sufficient engine
braking cannot be applied)
 Slippery roads such as ice or snow-bound
roads ( Tires could spin causing you to
lose vehicle control)
Always drive carefully:
The warnings and brake control will not
operate after the headway control function
is canceled and the system is switched to
only the cruise control function. Depress
the brake pedal to decelerate according to
the surrounding conditions while keeping a
safer distance from the vehicle ahead and
always driving carefully.

specified type and size for the front and rear wheels. Consult an
Authorized Mazda Dealer for tire replacement.
NOTE
When the turn signal lever is operated for a lane change, the LAS&LDWS is
automatically disabled. The LAS&LDWS becomes operational again when the turn signal
lever is returned and the system detects white (yellow) lane lines while the vehicle is being
driven normally within its vehicle lane.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white (yellow) line, the system determines that the driver is
making a lane change and the LAS&LDWS operation is temporarily canceled. The
LAS&LDWS becomes operational again when the system detects white (yellow) lane lines
while the vehicle is being driven normally within its vehicle lane.
If the vehicle deviates from its lane repe atedly within a short period of time, the
LAS&LDWS may not operate.
