NOTE
The specified maximum permitted trailer
weights are those permitted by Polestar.
National vehicle regulations may further
restrict trailer weight and speed. The
towbars can be certified for higher tow-
ing weights than the car is allowed to tow.
Trailer Stability Assist
The function for Trailer Stability Assist (TSA
141
)
is included in the ESC
142
stability system, and its
purpose is to stabilise a car with a trailer con-
nected in situations where the vehicle combina-
tion has begun to fishtail. The function is added
during the installation of the towbar, contact
Polestar Support for more information.
Causes of fishtailing
The phenomenon where a car with a trailer
starts to fishtail may occur for all car-trailer com-
binations. High speeds are normally required for
this to occur. But if the trailer is overloaded or
the load is distributed incorrectly, e.g. too far
back, there is a risk of fishtailing even at lower
speeds.
Factors causing fishtailing may, for example,
include the following:
• A sudden strong gust of wind from the side
affects the car with the trailer.
• The car with the trailer drives along an
uneven surface or into a pothole.
• Violent steering wheel movements.
Once the car has begun to fishtail, it may be diffi-
cult or impossible to stop it doing so. This makes
the vehicle combination difficult to control, with
a risk of it ending up in the wrong lane or leaving
the roadway.
Trailer Stability Assist function
Trailer Stability Assist constantly monitors the
car's movements, particularly sideways. If fish-
tailing is detected, individual brake control takes
place at the front wheels, which helps to stabi-
lise the combination. This is usually enough to
allow the driver to regain control of the car.
