neither reduce the ris
kofaccident nor over-
rid ethe laws of physics .Driving safety sys-
tems are merel yaidsd esigned to assist driv-
ing. You are responsible for the distance to
the vehicl einfront, for vehicl espee dand for
braking in good time. Always adapt yourd riv-
ing style to suitt he prevailing road and
weather conditionsa nd maintainasafe dis-
tance from the vehicle in front.D rive care-
fully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tyres and
the road surface. Please pay special atten-
tion to the notes on tyres, recommended
minimum tyre tread depths, etc.
(Y page 328).
In wintry driving conditions, always use
winter tyres (M+S tyres) and, if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. ABS (Anti-lockB
raking System)
Important safety notes i
Observe the "Important safety notes" sec-
tio n(Ypage 62). G
WARNING
If ABS is faulty, the wheels could lock when
braking .The steerability and braking charac-
teristics may be severely impaired. Addition-
ally,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aqualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 261) and
displaym essages which may be shown in the
instrumentc luster (Ypage 232). ABS regulates brake pressure in such
away
that the wheels do not lock when you brake.
This allowsy ou to continue steering the vehi-
cle when braking.
ABS works from aspeed of about 8km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.
The yellow !ABS warning lamp in the
instrumentc lusterlight supw hen the ignition
is switched on. It goes out when the engine is
running.

If ABS intervenes: continue to depressthe

uation is over.
X To make afull brake application:

WARNING
If BA Sism alfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automaticallyb oosts the braking force,
thus shortening the stopping distance.

If you brake sharply from aspeed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly.
In this way,t raffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspeed of more
than 70 km/h to astandstill, the hazard warn-
ing lamps are activated automatically .Ifthe
brakes are applied again, the brake lamps
light up continuously.T he hazard warning
lamps switch off automatically if you travel

the hazard warning lamps using the hazard

Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 62). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Vehicles with 4MATIC: switch off the igni-
tion when the parking brake is being tested
using adynamometer.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
Vehicles without 4MATIC: observe the notes
on ESP ®
if the vehicle is being towed with the
rear axle raised (Y page 322).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to amalfunction.
Observe the information on warning lamps
(Y page 263) and display messages which
may be shown in the instrument cluster
(Y page 232).
If ESP ®
detect sthat the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP ®
assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilise the vehicle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster. Driving safety systems
65Safety Z

If ESP
®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depres sthe accel-
erator pedalasf ar as is necessary.
X Adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
.

Driving safety systemsSafety

This function will issue
awarning if:
R at speeds of around 30 km/ho rmore, over
several seconds, the distance maintained
to the vehicle travelling in front is insuffi-
cient.
The · distance warning lamp then lights
up in the instrument cluster.
R at as peed of approximately 7km/h or
higher, you very quickly approach avehicle
in front.
An intermittent warning tone willt hen
sound and the ·distance warning lamp
willl ight up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicl einfront.
or
X Take evasive action provided it is safe to do
so.
From aspee dofa pproximatel y7km/h,ifthe
driver and passengers have fastened their
seat belts, PRE-SAFE ®
Brake can brake the
vehicl eautomatically at speeds up to approx-
imatel y200 km/h.
Due to the nature of the system, particularly
complicate ddriving conditions may cause
unnecessary warnings or the unnecessary
interventio nofPRE-SAFE ®
Brake.
You can prevent the interventio nofthe PRE-
SAFE ®
Brake at any time by:
R depressing the accelerato rpedal further
R activating kickdown
R releasing the brake pedal.
The brakin gaction of PRE-SAFE ®
Brak eis
ended automatically if:
R you manoeuvre to avoid the obstacle.
R ther eisnol onger any danger of arear-end
collision.
R ther eisnol onger an obstacle detected in
fron tofy our vehicle.
With the help of the radar sensor system,
PRE-SAFE ®
Brak ecan detec tobstacles that
are in fron tofyour vehicle for an extended
period of time. At speeds up to approximately 70 km/h, PRE-
SAFE
®
Brak ecan also detec tstationary
obstacles such as stopped or parked vehi-
cles.
If you approach an obstacle and PRE-SAFE ®
Brak edetects arisk of acollision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action ,the
system will warn you by automatically braking
the vehicle gently. If ther eisanincreased risk
of collision, preventativ epassenger protec-
tion measures (PRE-SAFE ®
)a re activated
(Y page 48). If, at speeds over 30 km/h, arisk
of collision remains and you do not brake,
take evasive action or significantly acceler-
ate, automatic brakin gmay be performed up
to alevel of automatic emergency braking.
Automatic emergency brakin gisnot per-
formed until immediately prior to an accident
that can no longer be avoided. G
WARNING
PRE-SAFE ®
Brak ewill initially brake your vehi-
cle by apartial application of the brakes if a

tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brak emay:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
