Important safety notes If ESP

detect sthat the vehicle is deviating
from the direction desired by the driver ,one
or more wheels are braked to stabilis ethe
vehicle. If necessary, the engin eoutput is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
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
flashes in the instrument cluster. G
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
axle raised. Interven tion by ESP ®
coul doth-
erwise damage the brake system.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP

Traction control brakes the drive wheels indi-
viduall yifthey spin. This enables you to pull
away and accelerate on slipper ysurfaces, for
example if the road surface is slippery on one

It may be best to deactivate ESP ®

Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®

If you deactivate ESP ®
:
R ESP ®

R the engine's torque is no longer limited and
the drive wheels can spin. The spinnin gof
the wheels results in acutting action, which
provides better grip.

Risk of accident
Yo uc oul dcause an accident if your rea rview
is limited by darkness or other conditions.
Therefore, fold back the upper section of the
draught stop if it restricts your vision or when
it is dark.
! Mercedes-Benz recommends that you
only use draught stops which have been
tested and approved for Mercedes-Benz
vehicles. This helps to prevent damage to
the vehicle.
! Observe the backrest position of the front
seats if the draught stop is installed, since
the backrest could collide with the draught
stop here. X
When installing the draught stop, use lat-
eral brackets :.
Observe the manufacturer' sinstallation
