WARNING
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and åwarning
lamp are lit continuously, ESP ®
is not availa-
ble due to amalfunction.
There is an increased risk of your vehicle skid-
ding in certain situations.
You shoul dalway sadapt your driving style to
suit the prevailing road and weather condi-
tions. X
To activate: press button :.
The å ESP®
OFF warning lamp in the
instrumen tcluster goes out.
Off- road ESP® An ESP
®
system specifically suited to off-road
terrain is activated automatically once the off-
road program (Y page 222)isa ctivated. It
intervene swithadelay if there is oversteering
or understeering, thus improvin gtraction.
ESP ®
traile rstabilisation If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilis ethe 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 brakin gand limiting the engine output until
the vehicle/traile rcombination has stabi-
lised.
Trailer stabilisation is active abov espeeds of
about 60 km/h. G
WARNING
If road and weather condi tions 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 wit hahigh centr eofgravity can tip over
before ESP ®
can detec tthis.
Trailer stabilisation does not work if ESP ®
is
deactivated or disable dbecause of amal-
function. EBD (electronic brake force distribu-

Adaptiv eHighbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker
The syste mmay not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whos elighting is not clearly visi-
ble, e.g. road users behind acras hb arrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
