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-

Off- road ESP® An ESP

system specifically suited to off-road
terrain is activated automatically once the off-

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-

e.g. under full braking. This coul dcaus eyou
to lose control of your vehicle and cause an
accident. You shoul dtherefore adapt your
