GWarning
Never switch off the ESP®
when you see the
d warning lamp flashing in the instrument
cluster. In this case proceed as follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP ®
cannot
prevent accidents resulting from excessive
speed.
! Only operate the vehicle for a maximum
of ten seconds on a brake test
dynamometer. Switch off the ignition.
Application of the brakes by ESP ®
may
otherwise destroy the brake system.
! Function or performance tests may only
be performed on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult an
authorized Mercedes-Benz Center
beforehand. You could otherwise damage
the drive train or the brake system.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
4ETS (Electronic Traction System)
GWarning
Observe "Important safety instructions"
( Y page 67).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.
Deactivating/activating ESP ®GWarning
The ESP
®
should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP ®
when a spare
wheel is mounted.
ESP ®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
GWarning!
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilize the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
When you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the d warning lamp in the
instrument cluster flashes. In such situations,
ESP ®
will not stabilize the vehicle.

Preparing the vehicle
Your vehicle may be equipped with a
collapsible spare wheel or the MOExtended
run-flat system ( Y page 307).
i Vehicle preparation is not necessary on
vehicles with the MOExtended run-flat
system.
i Vehicles featuring the MOExtended run-
flat system are not equipped with the
TIREFIT kit. It is therefore recommended
that you additionally equip your vehicle
with the TIREFIT kit if you mount tires that
do not feature run-flat properties, e.g.
winter tires. You can obtain a TIREFIT kit
from an authorized Mercedes-Benz Center,
for example.
