In poor road and weather conditions, the
trailer stabilisation cannot pr event lur ching of
th eve hicle/trailer combination. Trailers with a
high cent reofgrav ity may tip over before
ESP ®
de tects this. #
Always adapt your driving style tosuit

®
can stabilise
yo ur vehicle if the trailer begins toswer vefrom
side toside:
R ESP ®
trailer stabilisation is active abo ve
speeds of 65 km/h.
R Slight swerving is reduced bymeans of a tar-
ge ted, individual brake application on one
side.
R Intheev ent of se vere swerving, the engine
output is also reduced and all wheels are
braked. ESP

When Active Distance Assist DISTRONIC is acti va-

to thero ute events ahead. Depending on the drive
prog ram selected, theve hicle neg otiates a route
ev ent ahead in an economical, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-

Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 244).
The following route events are take n into account:
R Bends R

R Turns and exits
R Tra1c jams ahead (only with Live Tra1c Infor-

Also, the speed is reduced if the turn signal indi-
cator tochange lanes is switched on and one of
th efo llowing situations is de tected:
R Turning o. at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down

The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts and
