due tochildren left unatte nded inthe
ve hicle
If yo u lea vechildren unaccompanied in the
ve hicle, they may be able toset theve hicle in
motion, forex ample by:
RRe leasing the parking brake.
RShifting the transmission out of park
position j.
RStarting the engine.
In addition, they may operate vehicle equip‐
ment.
#Ne ver lea vechildren and animals unat‐
te nded in theve hicle.
#When leaving theve hicle, alw aysta ke
th e SmartK eywith you and lock the
ve hicle.
The electric parking brake is applied if the trans‐
mission is in position jand one of thefo llow‐
ing conditions is fulfilled:
RThe engine is switched off.
RThe seat belt tongue is not inser ted in the
seat belt buckle of the driver's seat and the
driver's door is opened.
% Toprev ent application: pull the handle of the
electric parking brake.
In thefo llowing situations, the electric parking
brake is also engaged:
RThe Dis tance Pilot DISTRONIC brings the
ve hicle toast andstill.
RThe HOLD function is keeping theve hicle sta‐
tionar y.
RParking Pilot is keeping theve hicle station‐
ar y. This is only
the case if one of thefo llowing con‐
ditions is also fulfilled:
RThe engine is switched off.
RThe seat belt tongue is not inser ted in the
seat belt buckle of the driver's seat and the
driver's door is opened.
RThere is a sy stem malfunction.
RThe po wer supply is insuf ficient.
RThe vehicle is stationary for a lengt hyperiod.
When the electric parking brake is applied, the
F (USA) or !(Canada) indicator lamp
lights up in the instrument clus ter.
The electric parking brake is not automatically
applied if the engine is switched off bythe ECO
st art/ stop function.
Re leasing the electric pa rking brake auto‐
matically
The elect ric park ing brake is released when the
fo llo wing c
onditions are fulfilled:

Fu nctions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, the wheels are pr evented
from blocking, forex ample due tomaximum
full-s top braking or insuf ficient traction of the
tires.
RVe hicle steerability while braking is ensured.
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
If ABS inter venes when braking, youwill feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.
Sy stem limits
ABS may be impaired or may not function if a
malfunction has occur red and theye llow !
ABS warning lamp lights up continuously in the
instrument clus ter af terth e engine is star ted.
Fu nction of BAS (Brake Assist Sy stem)
&
WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
te m)
If BA S is malfunctioning, the braking dis tance
may increase in an eme rgency braking situa‐
tion.

#Depress the brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.
BA S suppo rts yo ur eme rgency braking situation
with additional brake forc e.
If yo udepr essthe brake pedal quickl y,BA S is
acti vated:
RBA S au tomatical lyboosts the brake pres‐
sure.
RBA S can short enthe braking dis tance.
RABS pr events the wheels from locking.
The brakes will function as usual once you
re lease the brake pedal. BAS is deactivated.
Functions of ESP®(Electronic Stability Pro‐
gr am)
&
WARNING Risk of skidding if ESP®is
malfunctioning
If ESP
®is malfunctioning, ESP®cannot car ry
out vehicle stabilization. In addition, other
driving saf etysy stems are switched off.
#Drive on carefull y.
#Have ESP®checked at a qualified spe‐
cialist workshop.
&
WARNING Risk of skidding if ESP®is
deactivated
If yo u deactivate ESP
®, ESP®cannot car ry
out vehicle stabilization.
#ESP®should only be deactivated in the
fo llowing situations.
ESP®monitors and impr oves driving stability and
traction, particular ly inthefo llowing situations:
RWhen pulling away on wet or slippe ryroads.
RWhen braking.
RIn stro ng sidewinds when you are driving
fast erthan 50 mph (80 km/h).
ESP
®can stabilize theve hicle byinter vening in
th efo llowing ways:
ROne or more wheels are braked.
RThe engine output is adap ted according to
th e situation.
ESP
®is deactivated if the ESP®OFF å warn‐
ing lamp lights up continuously in the instrument
clus ter:
RDriving stability will no longe r be improved.
RCrosswind Assist is no longer active.
RThe drive wheels could spin.
RETS/4ETS traction control is still active.
% Even when ESP
®is deactivated, you are still
assis tedby ESP®when braking.
ESP
®is inter vening if the ESP®÷ warning
lamp flashes in the instrument clus ter:
RDo not deacti vate ESP®.

Driving and pa rking
ROnly depressthe accelera tor pedal as far as
is necessar y.
RAdapt your drivin gst yle to suit the cur rent
ro ad and weather conditions.
Deactivate ESP
®in thefo llowing situations to
impr ove traction:
Rwhen using snow chains
Rin deep snow
Ron sand or gr avel
% Spinning the wheels results in a cutting
action which pr ovides better grip. ESP
®is deactivated if
theå ESP®OFFwarn‐
ing lamp lights up continuously in the instrument
clus ter.
If th e ESP
®÷ warning lamp lights up continu‐
ousl y,ESP®is not available due toa malfunction.

RWa rning and indicator lamps (→page 423)
RDisplay messages (→page 380)
ETS/4ETS (Electronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP
®. ETS/4ETS can impr
ovetheve hicle's traction by
inter vening in thefo llowing ways:
RThe drive wheels are braked individually if
they spin.
RMore 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
th e driver's prefer red driving style. You can
selec
t the drive prog rams using theDY NA MIC
SELECT switch.
