Important safet ynotes
If you fail to adapt your drivin gstyle or if you
are inattentive ,th edrivin gsafet ysystems can
neither reduce th eris kof an acciden tno r
override th elaws of physics. Driving safet y
systems are merely aids designed to assist
driving. You are responsible fo rmaintainin g
th edistanc eto th evehicle in front, fo rvehicle
speed, fo rbraking in goo dtime, and fo rstay-
in gin lane. Always adapt your drivin gstyle to
suit th eprevailin groad and weather condi-
tion sand maintain asaf edistanc efrom th e
vehicle in front. Drive carefully.
The drivin gsafet ysystems described only
wor kas effectively as possible when there is
adequat econtact between th etires and th e
road surface. Please pay special attention to
th enote son tires ,recommended minimum
tire tread depths, etc. (
Ypage 404).
In wintr ydrivin gconditions, always use winte r
tires (M+ Stires )and if necessary, snow
chains. Only in this way will th edrivin gsafet ysystems described in this section wor
kas
effectively as possible.
ABS (Anti-lock Braking System)
General information
AB Sregulates brake pressure in suc h away
that th ewheels do no tloc kwhen you brake .
Thi sallow syou to continue steerin gth evehi-
cl e when braking .
The ! ABSwarnin glamp in th einstrumen t
cluster lights up when th eignition is switched
on .It goe sout when th eengin eis running .
AB Sworks from aspeed of about 5mph
(8 km/h), regardles sof road-surfac econdi-
tions. AB Sworks on slipper ysurfaces, eve n
when you only brake gently.
Important safet ynotes
iObserv eth e"Important safet ynotes" sec -
tion (
Ypage 68) .
GWARNING
If AB Sis faulty, th ewheels could loc kwhen
braking .The steerability and braking charac -
teristics may be severely impaired. Addition -
ally, further drivin gsafet ysystems are deac -
tivated. There is an increase ddanger of skid-
din gand accidents .
Drive on carefully. Hav eAB Schecke dimme-
diately at aqualified specialis tworkshop .
WhenAB Sis malfunctioning, other systems ,
includin gdrivin gsafet ysystems ,will also
becom einoperative .Observ eth einformation
on th eAB Swarnin glamp (
Ypage 327) and
display message swhic hmay be shown in th e
instrumen tcluster (

Possible causes are:
RSelf-diagnosis is not yet complete.
Rthe on-board voltage may be insufficient.
GWARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP
®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XCarefully drive a suitable distance, making slight steering move-
ments at a speed above 12 mph (20 km/h).
If the display message disappears, the functions mentioned
above are available again.
If the multifunction display still shows the display message:
