from the direction desired by the driver ,one
or more wheels are braked to stabilis ethe

modified to keep the vehicle on the desired
course within physical limits. ESP ®

the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
If ESP ®
intervenes, the äwarning lamp

Risk of accident
If the ä warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise ,the vehicle coul dskid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! The ignition must be switched off if you
are towing the vehicl ewith the front/rear

coul doth-
erwise damage the brake system.
