trailer stabilisation
General notes
If your vehicle/trailer combination begins to
lurch, ESP
®
assists you in this situation. ESP
®
slows the vehicle down by braking and limiting
the engine output until the vehicle/trailer com-
bination has stabilised.
Important safety notes
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.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/trailer
combination by depressing the brake firmly.
ESP
®
trailer stabilisation is active above speeds
of approximately 65 km/h.
ESP
®
trailer stabilisation does not work if ESP
®
is deactivated or disabled because of a malfunc-
tion.
