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 Indication/Warning
Lights on page 4-26 .
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.
N O T E
y 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.
y 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 Indication/Warning
Lights on page 4-26 .

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.
N O T E
To turn off the TCS, press the DSC OFF
switch (page 4-68 ).
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 À 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
Authorized Mazda Dealer.
N O T E
y In addition to the indicator light
À ashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
y On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

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 maneuvering,
enhancing vehicle safety.
Refer to ABS (page 4-65 ) and TCS
(page 4-66 ).
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 Indication/Warning
Lights on page 4-26 .
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

You can still have an accident.
CAUTION
¾ The DSC may not operate correctly
unless the following are observed:
¾ Use tires of the correct size specifi ed
for your Mazda on all four wheels.
¾ Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
¾ Do not mix worn tires.
¾ The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched

N O T E
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 traf ¿ c
conditions.
y When there are sources of light in the area such as street lamps, illuminated signboards,
and traf ¿ c signals.
y When there are re À ective objects in the surrounding area such as re À ective plates and
signs.
y When visibility is reduced under rain, snow and foggy conditions.
y When driving on roads with sharp turn or hilly terrain.
y When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim
or not illuminated.
y When there is suf ¿ cient darkness such as at dawn or dusk.
y When the luggage compartment is loaded with heavy objects.
y When visibility is reduced due to a vehicle in front of you spraying water from its tires
onto your windshield.

Tire Pressure Monitoring System
*Some models.
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the speci ¿ ed
tire pressure (value on the tire pressure label). Follow the procedure and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-108 .
The warning light À ashes when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-26 .

When Driving
Tire Pressure Monitoring System
CAUTION
¾ Each tire, including the spare (if provided), should be checked monthly when cold and
infl ated to the infl ation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire infl ation pressure label. (If your vehicle has tires of a diff erent size than the
size indicated on the vehicle placard or tire infl ation pressure label, you should determine
the proper tire infl ation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system ( TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is signifi cantly under-infl ated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and infl ate them to the proper
pressure. Driving on a signifi cantly under-infl ated tire causes the tire to overheat and can
lead to tire failure. Under-infl ation also reduces fuel effi ciency and tire tread life, and may
aff ect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if under-infl ation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will fl ash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
¾ To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously register a rapid tire defl ation or blow out.

When Driving
Tire Pressure Monitoring System
N O T E
Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases:
y The size, manufacturer, or the type of tires is different from the speci ¿ cation.
y The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them.
y A run- À at tire, studless tire, snow tire, or tire chains are used.
y An emergency tire is used (The tire pressure monitoring system warning light may À ash
and then continue illuminating).
y A tire is repaired using the emergency À at tire repair kit.
y The tire pressure is excessively higher than the speci ¿ ed pressure, or the tire pressure is
suddenly lowered for some reason such as a tire burst during driving.
y The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle is
stopped), or the drive period is shorter than 5 minutes.
y The vehicle is driven on an extremely rough road or a slippery, icy road.
y Hard steering and rapid acceleration/deceleration are repeated such as during aggressive
driving on a winding road.
y Load on the vehicle is applied to a tire such as by loading heavy luggage to one side of
the vehicle.
y System initialization has not been implemented with the speci ¿ ed tire pressure.

When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
y A tire pressure is adjusted.
y Tire rotation is performed.
y A tire or wheel is replaced.
y The battery is replaced or completely
drained.
y The tire pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe place and ¿ rmly
apply the parking brake.
2. Let the tires cool, then adjust the tire
pressure of all four (4) tires to the
speci ¿ ed pressure indicated on the tire
pressure label located on the driver's
door frame (door open).
Refer to Tires on page 9-8 .
3. Switch the ignition ON.
4. Press and hold the tire pressure
monitoring system set switch and
verify that the tire pressure monitoring
system warning light in the instrument
cluster À ashes twice and a beep sound
is heard once.
CAUTION
If the system initialization is performed
without adjusting the tire pressure,
the system cannot detect the normal
tire pressure and it may not illuminate
the tire pressure monitoring system
warning light even if a tire pressure is
low, or it may illuminate the light even
if the pressures are normal.
Adjust the tire pressure on all four
tires and initialize the system when
the warning light is turned on. If the
warning light turns on for a reason
other than a fl at tire, the tire pressure
of all four tires may have decreased
naturally.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.
