Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to
help stabilize a vehicle that is towing a trailer
when the vehicle and trailer have begun to sway
and is part of the Electronic Stability Control sys-
tem.
Function
A vehicle towing a trailer may begin to sway for
various reasons. Normally this only occurs at high
speeds but, for example, if the trailer is overloa-
ded or if the load is unevenly distributed in the
trailer, there is risk of swaying.
Swaying may be caused by factors such as:
•
The vehicle and trailer are hit by a sudden,
strong crosswind
•
The vehicle and trailer are traveling on an
uneven road surface or drive over a bump
•
Sudden movements of the steering wheel
Facts about TSA
•
The stability system symbol in the instrument
panel will flash when TSA is working
•
If the driver switches off the stability system's
Spin Control function, TSA will also be
switched off (but will be on again the next
time the engine is started)
•
TSA may not intervene when the vehicle and
trailer begin to sway if the driver tries to com-
pensate for the swaying motion by moving
the steering wheel rapidly
