can monitor and impr ovedriving stability
and traction in thefo llowing situations, within
ph ysical limits:
R When pulling away on wet or slippe rycar ria‐

R When braking.
R Vehicles with trailer hitch: in trailer opera‐

trailer combination begins tosw ay from side
to side.
R Instro ng side winds when you are driving
fa ster than 75 km/h.
If th eve hicle deviates from the direction desired
by the driver, ESP ®
can stabilise theve hicle by
inter vening in thefo llowing ways:
R One or more wheels are braked.
R The engine output is adap ted according to
th e situation.

is necessary when pulling away. It can be advantageous
todeactivate ESP ®
in the
fo llowing situations toimpr ovetraction:
R When using snow chains.
R In deep sn ow.
R On sand or gr avel.
% Spinning the wheels results in a cutting
action, which enhances traction.

ETS/4ETS (Electronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP ®
and
makes it possible topull away and accelerate on
a slippe rycar riag ew ay. If
yo u select theF drive prog ram, a special
ETS sy stem specifically suited tooff-road terrain
is automatically activated.

R The drive wheels are braked individually if
th ey spin.
R More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
The drive prog rams enable ESP ®
