When Driving
ABS/TCS/DSC/Trailer Stability Control (TSC)/Off-Road Traction Assist
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 Stability Control (TSC) is
operable at a vehicle speed of about 65
km/h (40 mph) or more.
When the Trailer Stability Control (TSC)
operates while driving the vehicle, the
TCS/DSC indicator light flashes.
Refer to TCS/DSC Indicator Light on page
4-105.
WARNING
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.
4-106
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 temporary 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.
For information regarding trailer

