ESP trailer stabilisation
If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
®
In this situation, ESP
detect when the trailer begins to lurch.
®
ESP slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilised.
Trailer stabilisation is active above speeds of
about 65 km/h.
G
Risk of accident
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the trailer from swerving and will thus be
unable to reduce the risk of an accident. Trail-
ers with a high centre of gravity can tip over
®
before ESP can detect this.
Trailer stabilisation does not work if ESP
deactivated or disabled because of a mal-
function.
ETS (Electronic Traction Support)
Traction control is part of ESP
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example, if the road surface is slippery on one
side.
Traction control remains active when you
®
deactivate ESP .

Risk of accident
