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.
When ESP ®
is deactivated, theå warning
lamp lights up continuously:
R Driving stability will no lon ger be impr oved.
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.
When the÷ warning lamp flashes, one or
se veral wheels has reached its grip limit:
R Adapt your driving style to suit the cur rent
ro ad and weather conditions.
R Do not deactivate ESP ®
.
R Only depress the accelerator pedal as far as
is necessary when pulling away. Deactivate ESP
®
in thefo llowing situations to
impr 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.
If th e÷ ESP®
wa rning lamp lights up continu‐
ousl y,ESP ®
is not available due toa malfunction.

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.
ETS/4ETS can impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
they 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 ®
to adapt todif‐
fe re nt we ather and road conditions as well as

HOLD function
The HOLD function holds
theve hicle at a stand‐
st ill without requ iring youto depress the brake
pedal, e.g. while waiting in traf fic.
The HOLD function is only an aid. The responsi‐
bility forth eve hicle safely standing still remains
with the driver.
Sy stem limits
The HOLD function is only intended toprov ide
assis tance when driving and is not a su fficient
means of safeguarding theve hicle against rolling

WARNING Risk of an accident due tothe
HOLD function being active when you
lea vetheve hicle
If th eve hicle is only braked with the HOLD
function it could, in thefo llowing situations,
ro llaw ay:
R Ifth ere is a malfunction in the sy stem or
in the po wer supp ly.
R Ifth e HOLD function is deactivated by
depressing the accelera tor pedal or brake
pedal, e.g. byave hicle occupant. #
Alw ays secure theve hicle against roll‐
ing away before you lea veit. Re
quirements:
R The vehicle is stationar y.
R The driver's door is closed or the seat belt on
th e driver's side is fastened.
R The engine is running or has been au tomati‐
cally switched off bythe ECO start/ stop
function. R
The electric parking brake is released.
R Active Dis tance Assi stDISTRONIC is deacti‐
va ted.
R The transmission is in position h,kori.
Ac tivating the HOLD function #
Dep ress the brake pedal, and af ter a short
time quickly depress fur ther until theë
display appears in the multifunction displa y. #
Release the brake pedal.
Deactivating the HOLD function #
Depress the accelerator pedal topull away.
or #
Depress the brake pedal until theë dis‐
play disappears from the multifunction dis‐
pla y.
The HOLD function is deactivated in thefo llow‐

R
The vehicle is secured with the electric park‐
ing brake.
In thefo llowing situations, theve hicle is held by
transmission position jand/or bythe electric
parking brake:
R The seat belt is unfas tened and the driver's
door is opened.
R The vehicle is switched off.
R There is a malfunction in the sy stem or the
po we r supp lyis insuf ficient. Fu
nction of Hill Start Assist Hill
Start Assist holds theve hicle for a short
time when pulling away on a hill under thefo l‐
lowing conditions:
R The transmission is in position hork.
R The elect ric pa rking brake is released.
This gives you enough time tomo veyour foot
from the brake pedal tothe accelerator pedal
and depress it before theve hicle begins toroll
aw ay. &
WARNING Risk of accident and inju ry
due totheve hicle rolling away
Af ter a short time, Hill Start Assist no lon ger
holds theve hicle. #
Swiftly mo veyour foot from the brake
pedal tothe accelera tor pedal. Do not
lea vetheve hicle when it is being held
by Hill Start Assist. Fu
nction of Adaptive Brake Lights Ad
aptive Brake Lights warnfollowing traf fic in an
emergency braking situation wi th thefo llowing
actions:
R Byflashing the brake lamps
R By activating the hazard warning lights
If th eve hicle is braked sharply from speeds
abo ve50 km/h, the brake lamps flash rapidl y.
This pr ovides traf fic tr avelling behind you with an
ev en more noticeable warning.
If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once th
eve hicle is stationar y.When you pull away
again, the hazard warning lights will switch off
automatically at appr oximately 10km/h. Yo u
can also switch off the hazard warning lights
using the hazard warning button. AT
TENTION ASSI ST Fu
nction of ATTENTION ASSI ST
AT TENTION ASSIST assists you on long, mon oto‐
nous jou rney s, e.g. on mo torw ays and trunk
ro ads. If ATTENTION ASSIST de tects indicators
of fatigue or increasing lapses in concentration
on the part of the driver, it suggests taking a
brea k.
AT TENTION ASSIST is only an aid. It cannot
alw ays de tect fatigue or lapses in concentration
in time. The sy stem is not a substitute for a well-
re sted and attentive driver. On long journe ys,
ta ke regular breaks in good time that allow for
adequate recuperation.
Yo u can choose between two settings:
R Standard: normal sy stem sensitivity. 174
Driving and pa rking

R
On slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for a short-term speed restriction,
e.g. in built-up areas
R Perm anen t:for a longer-term speed restric‐
tion, e.g. in winter tyre mode
Yo u can store any speed abo ve20 km/h up to
th e maximum design speed or up tothe set win‐
te r tyre limit. You can also per form settings
while theve hicle is stationary if theve hicle has
been star ted.
Obser vethe no tes on driving sy stems and your
re sponsibility; you may otherwise failto recog‐
nise dangers (/ page 168).
