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)
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 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 turn off the TCS, press the TCS OFF
switch (page 4-77).
▼
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)
▼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 4-75) and TCS
(page 4-76).

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
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.
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 4-73.
▼ 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.

i-ACTIV AWD Operation*
▼i-ACTIV AWD Operation
AWD provides excellent drivability on
snow-covered and ice-packed roads,
sand and mud, as well as on steep
slopes and other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to AWD Wa
rning Indication/
Warning Light on page 7-27.
WARNING
Never spin a wheel that is off the
ground:
Spinning a wheel that is off the ground
as a result of the vehicle being stuck or
in a ditch is dangerous. The drive
assembly could be seriously damaged
which could lead to an accident or
could even lead to overheating, oil
leakage, and a fire.
▼AWD Driving
WARNING
Avoid sharp turns, excessive speed
and abrupt maneuvers when driving
this vehicle:
Sharp turns, excessive speed and
abrupt maneuvering of this vehicle is
dangerous as it could result in the
increased risk of loss of vehicle control,
vehicle roll-over, personal injury or
death.
This vehicle has a higher center of
gravity. Vehicles with a higher center of
gravity such as utility and AWD vehicles
handle differently than vehicles with a
lower center of gravity.
Utility and AWD vehicles are not
designed for cornering at high speeds
any more than low profile sports cars
are designed to perform satisfactorily
under off-road conditions. In addition,
utility vehicles have a significantly
higher rollover rate than other types of
vehicles.
Drive carefully when the vehicle is
loaded by lowering vehicle speed and
applying the brakes earlier:
Abrupt maneuvering and sudden
braking when driving a loaded vehicle
is dangerous as the driving behavior of
a vehicle with a high center of gravity is
different when it is loaded compared
to when it is not, and could result in
the loss of vehicle control and an
accident.
▼Tires and Tire Chains
The condition of the tires plays a large
role in the performance of the vehicle.
Moreover, to prevent adverse
effects to
the drive assembly, please note the
following:
Tires
When replacing tires, always replace
all front and rear tires at the same
time.
All tires must be of the same size,
manufacture, brand and tread
pattern. Pay particular attention
when equipping snow or other types
of winter tires.
Do not mix tread-worn tires with
normal tires.
Inspect tire inflation pressures at the specified periods adjust to the
specified pressures.

Slippery roads such as ice or
snow-bound roads (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
 Long , descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
 Slopes with a st eep gradient (The
vehicle ahead may not be detected
correctly.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
For safety purposes, switch the MRCC
system off when it is not being used.
Leaving the MRCC system turned on
when it is not in use is dangerous as it
could operate unexpectedly, resulting
in an accident.
CAUTION
 Turn the system
off when the vehicle
is running on a chassis roller.

extremely low speed, the system
may not detect it correctly.
If there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC.
Do not use the MRCC system under
conditions in which close proximity
warnings are frequently activated.
During headway control travel, the
system accelerates and decelerates
your vehicle in conjunction with the
