stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP
® assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP
® slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has
stabilized.
Trailer stabilization is active from a speed of
approximately 40 mph(65 km/h).
G WARNING
The system will not be able to assist when the
trailer jackknifes
R if the ESP ® has switched off due to a
malfunction
R on wet or icy roads
R on roads with slippery surface
R in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying of
the trailer.
Trailer stabilization does not work if ESP ® is
deactivated or disabled because of a
malfunction.
