If you believe that your vehicle hasadefect
which could cause acrash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration
(NHTSA)ina ddition to notifying Mercedes-Benz
USA,L LC.
If NHTSA receives similar complaints ,itmay
open an investigation, and if it finds that asafety
defect exists in agroup of vehicles, it may order
ar ecall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or Mercedes-Benz

card contains the most important information
about your vehicle in acompact form, e.g. the
routing of the electric cables.

These include, for example:
Roperating conditions of system components,
e.g. fluid levels
Rthe vehicle's status messages and those of its
individual components, e.g. number of wheel

Introduction

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.

Function
Starting at aspeedofa pproximately 4mph
(7 km/h), th edistanc ewarning function warns
you ifyou rapid ly approachav ehicle in front. An
intermittentw arning tonewillthen sound, and
the · distancewarning lamp willlight up in
th ei nstrumen tcluster.
XBrake immediately inorder to increas ethe
dist ancefromt heveh icle in front.
or
XTakee vasive action,p rovide ditiss afe todo
so.
Due to th enature of th esystem, particularly
co mpli cated but non-critical driving conditions
may also caus ethe system to displayaw arning.
Witht hehelp of th eradar sensor system, the
dist ancewarning function can detect obstacles
that are inthep athofy our veh iclefor an exten-
ded period of time.
Up to aspeedofa pproximately 44 mph
(70 km/ h),t he distance warnin gfunction can
also react to stationary obstacles, such as stop-
ped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance warn-
ing signal in acritical situation, Active Brake
Assis tcan assist with the autonomous braking
function.
If the autonomous brakin gfunction requires a
particularly high brakin gforce, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneously.
Vehicles without Distance Assist
DISTRONIC: the autonomous brakin gfunction
is available in the following speed ranges:
R4-65m ph (7-105 km/ h)for moving objects
R4-31m ph (7-50km/h)for stationary
objects
Vehicles with Distance Assist DISTRONIC:
the autonomous braking function is available in
the following speedr anges:
R4-124 mph (7 -200 km/h )for moving
objects
R4-31m ph (7-50km/h)for stationary
objects
Due to the nature of the system ,particularly
complicated but non-critical driving conditions
may als ocaus ethe Autonomou sBraking Func-
tion to intervene. If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneousl y(Ypage53).
Adaptive Brake Assist
General information
iObservet he "Important safety notes" sec-
tion (Ypag e56).
With the help of adaptive Brake Assist, the dis-
tance warning signalc an detect obstacles that
are in the path of you rvehiclef or an extended
period of time.
If adaptive Brake Assist detects arisk of colli-
sion with the vehicleinf ront, it calculatesthe
braking force necessary to avoi dacollision. If
you apply the brakes forcefully ,adaptive Brake
Assist wil lautomatically increas ethe braking
force to alevels uitabl efor the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardouss ituations at speeds above
4m ph (7 km/h) .Itusesrada rsensor technology
to assess the traffic situation.
Up to aspeedofa pproximately 155 mph
(250 km/h) ,adaptive Brake Assist is capable of
reacting to moving objects that have already
been detected as such at least once over the
period of observation.
Up to aspeedofa pproximately 44 mph
(70 km/h), adaptive Brake Assist reacts to sta-
tionary obstacles.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger pro-
tection measures (PRE-SAFE
®)a re activated
simultaneousl y(Ypage53).
XKeep the brake pedald epressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes wil lwork normally again if:
Ryou release the brake pedal.
Rthere is no longera ny dangerofacollision.
Rno obstacle is detected in front of you rvehi-
cle.
Adaptive Brake Assist is then deactivated.
