the vehicle begins to skid, ESP brakes the appropriate wheel auto-
matical
ly.
The vehicle is stabilized again by the forces acting on the wheel
during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed
.
This brake application is accompanied by noises.
ESP works in conjunction with ABS=:> page

If there is ma lfunc-
tion in the ABS, ESP is also inoperative

The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode
.
With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=> page 184, fig. 132 returns the
system to normal operation.

ESP should norma lly be activated at all times because this ensures
optimum vehicle stability

Only in certain exceptional cases it does
make sense to deactivate Anti -Slip Regulation (ASR) or the
Elec-
tronic Stability Program !ESP) by pressing the button =:> page 184,

Both deactivation stages can only be activated from normal

Deactivation is indicated by slow flashing of the ESP
lamp in the instrument cluster. In certain situations (e.g. driving
with snow chains, in deep snow or on loose ground, or when
rocking the car free), it may be necessary to deactivate ASR. Deacti

Deactivation is indicated

This deactivates the Electronic Stabi lity Program (ESP) in addition to
ASR.
No Electronic Stability System operation and no Anti-Slip
Regu lation is availab le across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stab le vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
