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®.

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.

in the instrument clus ter:
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.
