You are responsible for maintainingthe distance
to the vehicle in front, for vehicle speed, for
braking in good time, and for stayin ginlane.
Always adapt your drivings tyle to suit the pre-
vailing road and weather condition sand main-
tain asafe distance from the vehicle in front.
Drive carefully.
The drivings afetysystems described only work
as effectively as possible when there is ade-
quate contac tbetwee nthe tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tir et read depth setc.int he "Wheels and tires"
section (
Ypage 260).
In wintry drivingc onditions, always use winter
tires (M+S tires) and if necessary, sno wchains.
Only in this way will the drivings afetysystems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
Genera linformation
AB Sregulates brakep ressure in suchaway that
the wheels do not lock when you brake. This
allows you to continue steeringt he vehicle when
braking.
The ! ABSw arnin glamp in the instrument
cluster lightsupw hen the ignition is switched
on. It goes out when the engin eisrunning.
AB Sw orksf romaspeed of about 5mph
(8 km/h), regardless of road-surfacec onditions.
AB Sw orksons lippery surfaces, even when you
only brakeg ently.
Important safetyn otes
iObserve the "Importan tsafetyn otes" sec-
tion (Ypage 56).
GWARNING
If AB Sism alfunctioning, the wheels could
lock when braking. The steerabilitya nd brak-
ing characteristics would be severely affec-
ted. There is an increased danger of skidding and accidents.
Drive on carefully. Have AB Schecked imme-
diately at aqualified specialis tworkshop.
When AB Sismalfunctioning, other systems,
including drivings afetysystems, will also becom
einoperative .Observe the information
on the AB Swarnin glamp (
Ypage 204) and dis-
play messages which may be shown in the
instrumentc luster (
Ypage 179).
Brakes
XIf ABS intervenes: continue to depresst he
brakep edal vigorously until the braking sit-
uation is over.
XTo make afull brake application: depress
the brakep edal with full force.
If AB Sintervenes when braking, you will feel a
pulsing in the brakep edal.
The pulsatin gbrakep edal can be an indication
of hazardous road conditions, and function sasa
reminder to tak eextra care while driving.
BAS (Brake Assist System)
Genera linformation
BA So perates in emergenc ybraking situations.
If you depresst he brakepedal quickly, BAS
automatically boostst he braking force, thus
shortening the stopping distance.
Important safetyn otes
iObserve the "Importan tsafetyn otes" sec-
tion (Ypage 56).
GWARNING
If BA Sism alfunctioning, the braking distance
in an emergenc ybraking situation is
increased. There is arisk of an accident.
In an emergenc ybraking situation, depress
the brakep edal with full force. AB Sprevents
the wheels from locking.
Braking
XKeep the brakep edal firmly depressed until
the emergenc ybraking situation is over.
AB Sp revent sthe wheels from locking.
The brakes will function as usual onc eyou
release the brakep edal. BASisdeactivated.

washes that use textile washing elements with-
out brushes. This prevents fine scratches from
forming on the paintwork and film.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windshielda nd the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
iVehicles with decorative film: select awash
program without hot wax at the automatic car
wash.

GWARNING
The water jet from acircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nentsd amagedint his way may fail unexpect-
edly.T here is arisk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis componentsr eplaced imme-
diately.
!Vehicles with decorative foil: parts of your
vehicle are covered with decorative foil. Main-
tain adistance of at least 27.5 in (70 cm)
between the foil-wrappedp arts of the vehicle
and the nozzle of the high pressure cleaner.
Information aboutt he correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
The water temperature of the high-pressure
cleaner must not exceed 140 °F (60 °C).
!Alwaysm aintainadistance of at least
11.8 in (30 cm) between the vehicle and the

MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires. The affected tire must not show
any clearly visible damage.
You can recognize aMOExtended tire by the
MOExtended marking which appears on the
sidewal lofthe tire. You wil lfind this marking
next to the tire size designation, the load-bear-
ing capacity and the speedi ndex (
Ypage275).
MOExtended tires may only be use dinconjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure lossw arningmessagea ppears
in the multifunction display:
Robserve the instructions in the display mes-
sage s(Ypage1 96)
Rcheck the tire for damage
Rif driving on, observe the following notes
The driving distance possible in run-fla tmode is
approximately 50 mile s(80 km) when the vehi-
cle is partiall yladen and approximately 19 miles
(30 km) when the vehicleisf ullyladen.
In addition to the vehiclel oad, the driving dis-
tance possible depends upon:
Rvehicles peed
Rroad condition
Routside temperature
The driving distance possible in run-fla tmode
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 tmode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed amaximu mdesign speed
of 50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for you rvehicle's
tires:
Rsize
Rtype and
Rthe "MOExtended "mark
If at ire has gone flat and cannot be replaced
with aMOExtended tire, astandard tire may be
use dasat emporary mea
sure. Make sure thatyou use the propers
ize and type (summer or
winter tire).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommendedt hat you additionally
equip you rvehiclew ithaTIREFIT kit if you mount
tires that do not feature run-fla tcharacteristics,
e.g. winter tires. ATIREFIT kit can be obtained
from aqualified specialist workshop, for exam-
ple.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is arisk of an accident.
Do not exceed the stated maximu mspeed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This appliesinp articulartoaladen
vehicle.
Stop driving in emergency mode if:
Ryou hearb anging noises.
Rthe vehicles tarts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheelr ims checked at aqualified specialist
workshopw ith regard to their further use .The
defective tire must be replaced in every case.
