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 80 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.
ESP ®
is deactivated if theå ESP®
OFF warn‐
ing lamp lights up continuously in the instrument
clus ter. Obser
vethefo llowing points when ESP ®
is deac‐
tivated:
R Driving stability will no lon ger be impr oved.
R Vehicles with trailer hitch: stabilisation of
th eve hicle/trailer combination is no longer
active.
R Crosswind Assist is no longer active.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.
% When ESP ®
is deactivated, you are still assis‐
te dby ESP ®
when braking.
If th e÷ ESP®
wa rning lamp flashes in the

has reached its grip limit:
R Adapt the driving style to suit the pr evailing
ro ad and weather conditions.
R Do not deactivate ESP ®
under any circum‐
st ances.
R Onlydepress the accelerator pedal as far as
is necessar y. It may be best
todeactivate ESP ®
in thefo llow‐
ing situations:
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.
If th e÷ ESP®

WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the
trailer stabilisation cannot pr event lu rching of
th eve hicle/trailer combination. Trailers with
a high centre of gr avity may tip over before
ESP ®
de tects this. #
Alw ays adapt your driving style to suit
th e cur rent road and weather condi‐
tions. When driving with a trailer, ESP
®
can stabilise
yo ur vehicle if the trailer begins toswer vefrom
side toside:
R ESP ®
trailer stabilisation is active abo ve
speeds of 65 km/h.
R Slight swerving is reduced bymeans of a tar‐
ge ted, individual brake application on one
side.
R Intheeve nt of se vere swerving, the engine
output is also reduced and all wheels are
braked.
ESP ®

Pe
rm anent limi ter
If th eve hicle should ne verexc eed a specific
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
Yo u do this by limiting the speed toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (→ page 200).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you
confirm the message with %, display mes‐
sages no longer appear until you swit choff the
ve hicle. The speed will only be displa yed again
once theve hicle has been restar ted.
The permanent limiter does not switch topas‐
sive mode even du ring kickdown and the driven
speed remains below the set speed.

Driving Assi stance Package. If a
change in the speed limit is de tected and
Ac tive Dis tance Assi stDISTRONIC is acti vated,
Ac tive Dis tance Assi stDISTRONIC adapts this
new speed as thestored speed.
The driven speed is adjus ted when theve hicle is

case of signs indicating entry into an urban area,
th e speed is adap ted beforehand. The speed

If th ere is no speed restriction on an unlimi ted
