If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
ESP
®
(Electronic Stability Program)
i
See the "Important safety notes" section
If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP
®
assists
the driver when pulling away on wet or
slippery roads. ESP
®
can also stabilize the
vehicle during braking.
If ESP
®
intervenes, the
÷
ESP
®
warning
lamp flashes in the instrument cluster.
Under no circumstances should you
deactivate ESP
®
when the
÷
ESP
®
warning lamp in the instrument cluster
flashes. 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 to suit the prevailing road
and weather conditions.
Failure to observe these guidelines could
cause the vehicle to skid. 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)
i
Observe the "Important safety notes"
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 if you
deactivate ESP
®
.
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
i
Observe the "Important safety notes"
ESP
®
should not be deactivated during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not deactivate ESP
®
when the emergency
or spare wheel is mounted.
