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 4-32.
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 co uld still have an
accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-74).
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS, DSC or the Trailer Stability
Assist (TSA)
* 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.

▼TCS OFF Indicator Light
This indicator light
stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the TCS OFF
switch is pressed and TCS is switched off.
Refer to TCS OFF Switch on page 4-74.

If the light remains illuminated and the
TCS is not switched off, take your vehicle
to an Authorized Mazda Dealer. The DSC
may have a malfunction.
▼ TCS OFF Switch
Press the TCS OFF sw
itch to turn off the
TCS. The TCS OFF indicator light in the
instrument cluster and TCS OFF switch
indicator light turn on.
Indicator light
Press the switch agai n to turn the TCS
back on. The TCS OFF indicator light and
TCS OFF switch indica tor light will turn
off.
NOTE
•When TCS is on and you attempt to free
the vehicle when it is stuck, or drive it
out of freshly fallen snow, the TCS (part
of the DSC system) will activate.
Depressing the accelerator will not
increase engine power and freeing the
vehicle may be difficult. When this
happens, turn off the TCS.
•If the TCS is off when the engine is
turned off, it aut omatically activates
when the ignition is switched ON.
•Leaving the TCS on will provide the best
traction.
•If the TCS OFF switch is pressed and
held for 10 seconds or longer, the TCS
can no longer be turned off even if the
TCS OFF switch is pressed.
In this case, the TCS OFF switch will
operate normally when the ignition is
switched ON again after being switched
OFF.

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 -72) and TCS (page
4-73).

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 4-32.
WA R N I N G
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 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.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few

Trailer Stability Assist(TSA)
If the vehicle sways while being driven
and towing a trailer, the Trailer Stability
Assist (TSA) automatically controls
braking and engine torque to suppress the
swaying and enhance vehicle stability.
The Trailer Stability Assist (TSA) is
operable at a vehicle speed of about 65
km/h (40 mph) or more.
When the Trailer Stability Assist (TSA)
operates while driving the vehicle, the
TCS/DSC indicator light flashes.
Refer to TCS/DSC Indicator Light on page
4-75.
WA R N I N G
Do not rely solely on the Trailer Stability
Assist (TSA)
Assured vehicle stability is limited even if
the Trailer Stability Assist (TSA) is
operating. Drive carefully to prevent
accidents.
In particular, if the TCS/DSC indicator light
is flashing, drive the vehicle carefully as it is
in a less stable condition and could sway
more easily. Drive with caution and in
accordance with the road, vehicle and
trailer conditions.
CAUTION
The Trailer Stability Assist (TSA) 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 Trailer Stability Assist (TSA) may not
operate correctly when tire chains are
used or a temporary spare tire is installed
because the tire diameter changes.
NOTE
•The Trailer Stability Assist (TSA) uses
the TCS/DSC functions. The Trailer
Stability Assist (TSA) does not operate if
there is a malfunction in the TCS/DSC
(the TCS/DSC indicator light turns on).
•When the Trailer Stability Assist (TSA)
is operating, the brake lights may turn
on.
•For information regarding trailer
towing, refer to Trailer Towing (U.S.A.
and Canada) on page 3-56.

Drive Selection
Drive selection is a system to switch the vehicle's drive mode. When the sport mode is
selected, vehicle's response against accelerator operation is enhanced. This provides
additional quick acceleration which may be needed to safely mak e maneuvers such as lane
changes, merging onto freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when driving on slip pery roads such as wet or snow-covered roads.
It may cause tire slipping.
NOTE
•When the sport mode is selected, driving at higher engine speeds increases and it may
increase fuel consumption. Mazda recommends that you cancel the sport mode on normal
driving.
•Drive mode cannot be switched in the following conditions:
•ABS/TCS/DSC is operating
•The Mazda Radar Cruise Control (MRCC) system/cruise control is operating.
•Steering wheel is being operated abruptly

Power Steering
•Power steering is only operable when
the engine is running. If the engine is off
or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
•The warning indication/warning light
notifies the driver of system
abnormalities and operation conditions.
In addition, the buzzer may also activate
depending on the system abnormality or
operation condition.
Refer to Warning Indication/Warning
Lights on page 4-32.
Refer to Power Steering Warning

•During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
•While the MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
•The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
•The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating.
