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 4-104) and TCS (page
4-105).
DSC operation is possible at speeds
greater than 20 km/h (12 mph).
The warning light turns on when the
system has a malfunction.
Contact an Authorized Mazda Dealer and
Have Vehicle Inspected on page 7-31.
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 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.
▼ 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
Control (TSC) is ope
rating, 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.

Trailer Stability Control(TSC)
If the vehicle sways while being driven
and towing a trailer, the Trailer Stability
Control (TSC) automatically controls
braking and engine torque to suppress the
swaying and enhance vehicle stability.
The Trailer Stabili ty Control (TSC) is
operable at a vehicle speed of about 65
km/h (40 mph) or more.
When the Trailer Sta bility Control (TSC)
operates while driving the vehicle, the
TCS/DSC indicator light flashes.
Refer to TCS/DSC Indicator Light on page
4-107.
WA R N I N G
Do not rely solely on the Trailer Stability
Control (TSC)
Assured vehicle stability is limited even if
the Trailer Stability Control (TSC) 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 Control (TSC) 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 Control (TSC) may
not operate correctly when tire chains
are used or a temp orary spare tire is
installed because the tire diameter
changes.
NOTE
The Trailer Stability Control (TSC) uses
the TCS/DSC functions. The Trailer
Stability Control (TSC) does not operate
if there is a malfunction in the TCS/DSC
(the TCS/DSC indicator light turns on).
When the Trailer Stability Control (TSC)
is operating, the brake lights may turn
on.
