2018 MAZDA MODEL CX-9 trailer

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.
