&WARNING Risk of skidding if ESP®is
malfunctioning
If ESP®is malfunctioning, ESP®cannot carry
out vehicle stabilization. In addition, other
driving safety systems are switched off.
#Drive on carefully.
#Have ESP®checked at a qualified spe‐
cialist workshop.
You can select between thefollowing modes of
the Electronic Stability Program (ESP®):
RESP®ON
RESP®SPORT
RESP®OFF
Characteristics when ESP®is activated
ESP®monitors and improves driving stability and
traction, particularly in thefollowing situations:
RWhen pulling away on wet or slippery road.
12 Driving and parking

RWhen braking.
RIn strong side winds when you are driving
faster than 47 mph (75 km/h).
ESP®can stabilize thevehicle by intervening in
thefollowing ways:
ROne or more wheels are braked.
RThe engine output is adapted according to
the situation.
ESP®is activated every time the engine is star‐
tedregardless of whether ESP®was in ESP®
SPORT or deactivated before the engine was
switched off.
If the÷ESP®warning lamp flashes in the
instrument cluster, one or severalvehicle wheels
has reached its grip limit:
RAdapt the driving styleto suit the prevailing
road and weather conditions.
RDo not deactivate ESP®under any circum‐
stances.
ROnly depress the accelerator pedal as far as
is necessary.
Characteristics of ESP®SPORT
&WARNING Risk of skidding if ESP®
SPORT is used incorrectly
When you activate ESP®SPORT, there is an
increased risk of skidding and having an acci‐
dent.
#Activate ESP®SPORT only in the cir‐
cumstances described below.
When ESP®SPORT is activated, theåand
Æwarning lamps light up continuously in the
instrument cluster.
Select ESP®SPORT when thevehicle's own
oversteering and understeering characteristics
are desired, e.g. on cordoned off roads.
Driving with ESP®SPORT or with ESP®deactiva‐
tedrequires an extremely qualified and experi‐
enced driver.
If ESP®SPORT is activated and one or more
wheels start to spin, the÷ESP®warning
lamp on the instrument clusterflashes. ESP®
then only stabilizes thevehicle to a limited
degree.
ESP®SPORT also has thefollowing characteris‐
tics:
RESP®only improves driving stability to a limi‐
ted degree.
RETS/4ETS traction control is still active.
RThe engine's torque is only restricted to a
limited degree and the drive wheels can spin.
The spinning of the wheels results in a cut‐
ting action for better traction on loose surfa‐
ces.
RESP®continues to provide assistance when
the brakes are firmly applied.
RCrosswind Assist is no longer active.
Characteristics when ESP®is deactivated
&WARNING Risk of skidding if ESP®is
deactivated
If you deactivate ESP®, ESP®cannot carry
out vehicle stabilization.
Driving and parking 13

#ESP®should only be deactivated in the
following situations.
When ESP®is deactivated, theåand ¤
warning lamps light up continuously in the
instrument cluster.
Deactivating ESP®has thefollowing effects:
RDriving stability will no longer be improved.
RThe drive wheels could spin.
RETS/4ETS traction control is still active.
RCrosswind Assist is no longer active.
%Even when ESP®is deactivated, you are still
assistedby ESP®when braking hard.
It may be best to activate ESP®SPORT or deacti‐
vate ESP®in thefollowing situations:
RWhen using snow chains.
RIn deep snow.
ROn sand or gravel.
%Spinning the wheels results in a cutting
action, which enhances traction.
%Activate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize thevehicle
if thevehicle starts to skid or a wheel starts
to spin.
If the÷ESP®warning lamp lights up continu‐
ously even when ESP®is activated, ESP®is not
available due to a malfunction.
Observe any information which is displayed in
the instrument cluster:
RIndicator and warning lamps
RDisplay messages
ETS/4ETS (Electronic Traction System)
ETS/4ETS traction control is part of ESP®.
ETS/4ETS can improve thevehicle's traction by
intervening in thefollowing ways:
