trailer stabilisation General notes
If your vehicle/trailer combination begins to
lurch, ESP
®
assists you in this situation .ESP ®
slows the vehicle down by brakin gand limit-
ing the engin eoutput until the vehicle/trailer
combination has stabilised.
Important safet ynotes 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
ahigh centre of gravity can
tip over before ESP ®
can detec tthis. There is
ar isk 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 activ eabove
speeds of about 65 km/h.
ESP ®
trailer stabilisation does not work if
ESP ®
is deactivated or disabled because of a

General notes The Intelligent Light System is
asystem that
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function, cornering light function, motorway mode and
extended range foglamps. The system is only active when it is dark.
You can activate or deactivate the "IntelligentLight System" function using the on-board
computer (Y page 290).
