trailer stabilisa-
tion
G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high centre of gravity can
tip over before ESP
®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
ESP
®
trailer stabilisation can stabilise your vehi-
cle with trailer if it starts to swing from side to
side and you apply the brakes firmly:
R
ESP
®
trailer stabilisation is active from a
speed of 60 km/h and above.
R
slight swinging from side to side is reduced by
a targeted and one-sided brake application.
R
if severe swinging from side to side occurs,
engine output is also reduced and all the
wheels are braked.
