You are responsible for maintainin gt he distance
to the vehicle in front, for vehicle speed, for
braking in good time, and for stayin ginl ane.
Always adapt your drivin gs tyle to suit the pre-
vailing road and weather condition sa nd main-
tain as afe distance from the vehicle in front.
Drive carefully.
The drivin gs afet ys ystems described only work
as effectively as possible when there is ade-
quate contac tb etwee nt he tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tir et re ad depth se tc .int he "Wheels and tires"
section ( Y
page 260).
In wintry drivin gc onditions, always use winter
tires (M+S tires) and if necessary, sno wc hains.
Only in this way will the drivin gs afet ys ystems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
Genera li nformationAB Sr egulates brak ep ressure in such aw ay that
the wheels do not lock when you brake. This
allows you to continue steerin gt he vehicle when
braking.
The % AB Sw arnin gl amp in the instrument
cluster light supw hen the ignition is switched
on. It goes out when the engin eisr unning.
AB Sw ork sf rom as peed of about 5m ph
(8 km/h), regardless of road-surfac ec onditions.
AB Sw ork sons lippery surfaces, even when you
only brak eg ently.

G WARNING
If AB Sism alfunctioning, the wheels could
lock when braking. The steerabilit ya nd brak-
ing characteristics would be severely affec-
ted. There is an increased danger of skidding
and accidents.
Drive on carefully. Have AB Sc hecked imme-
diately at aq ualified specialis tw orkshop.
When AB Sism alfunctioning, other systems,
including drivin gs afet ys ystems, will also becom ei noperative .O bserve the information
on the AB Sw arnin gl amp ( Y

If ABS intervenes: continue to depres st he
brak ep edal vigorously until the braking sit-
uation is over. X
To make af ull brake application: depress
the brak ep edal with full force.
If AB Si ntervenes when braking, you will feel a
pulsing in the brak ep edal.
The pulsatin gb rak ep edal can be an indication
of hazardous road conditions, and function sasa
reminder to tak ee xtra care while driving.
BAS (Brake Assist System)
Genera li nformationBA So perates in emergenc yb raking situations.
If you depres st he brak ep edal quickly, BAS
automatically boost st he braking force, thus
shortening the stopping distance.

properties)
General notes With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rv ehi-
cle even if there is at otal loss of pressure in one
or more tires. The affected tire must not show
any clearly visible damage.
You can recognize aM OExtended tire by the
MOExtended marking which appears on the
sidewal loft he tire. You wil lf ind this marking
next to the tire size designation, the load-bear-
ing capacity and the spee di ndex ( Y
pag e2 75).
MOExtended tires may only be use dinc onjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.

check the tire for damage R
if driving on, observe the following notes
The driving distance possible in run-fla tm ode is
approximately 50 mile s( 80 km) when the vehi-
cle is partiall yl aden and approximately 19 miles
(30 km) when the vehicl eisf ull yl aden.
In addition to the vehicl el oad, the driving dis-
tance possible depends upon: R
vehicl es peedR
road condition R
outside temperature
The driving distance possible in run-fla tm ode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-fla tm ode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
