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 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th eve hicle/trailer combination is no longer
active.
R Crosswind Assist is no longer active.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‐

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

tions. When driving with a trailer, ESP
®
can stabilise
yo ur vehicle if the trailer begins toswer vefrom
side toside:
R ESP ®

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 ®

Sy
stem limitations
Te mp orary speed restrictions (e.g. for a cer tain
time or due towe ather conditions) cannot be
proper lyde tected bythe sy stem. The maximum
permissible speed applying for a vehicle with a
trailer is not de tected bythe sy stem. In these sit‐
uations you must adjust your speed yourself. &
WARNING Risk of accident due toActive
Speed Limit Assi stadapting theve hicle's
speed
The speed adop tedby Active Speed Limit
Assi stmay be too high or incor rect in some
individual cases, su chas:
R Inthewe t or in fog
R When towing a trailer #
Ensure that the driven speed complies
with traf fic re gulations. #
Adjust the driving speed tosuit cur rent
traf fic and weather conditions. Fu
nction of route-based speed adaptation %
The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package.
When Dis tance Assi stDISTRONIC is acti ve,the
function adju ststh e speed depending on the
ro ute events ahead. Depending on the drive pro‐
gram selected, theve hicle negotiates thero ute
eve nt ahead in a fuel-s aving, com fortable or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
st ored speed. The set dis tancetotheve hicle in
front, vehicles de tected ahead and speed restric‐
tions ahead are take n into account.
Ro ute-based speed adjustment can byconfig‐
ured in the multimedia sy stem
(/ page211).
Ro ute events ahead are:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
( / page 358)) %
When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed.
Also, the speed is reduced if the turn signal to
ch ange lanes is swit ched on and one of thefo l‐
lowing situations is de tected:
R Turning off at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts
and traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
When route guidance is active, thefirs t speed
adjustment is car ried out automaticall y.Ifthe
turn signal indica tor is switched on, the selected
ro ute is confirmed and fur ther speed adjustment
is activated. 210
