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
brak epedal with force until the braking sit-
uation is over.
X To make afull brake application:

tio n(Ypage 62). G
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.
The brakes will function as usualo nce you
release the brake pedal.B AS is deactivated. Dr

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 ®
.
Deactivating/activating ESP ®
(except
AMG vehicles) G
WARNING
If you deactivate ESP ®
,E SP ®

bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®

WARNING
If EB Dhas malfunctioned ,the rear wheels can
still lock, e.g .unde rfull braking .This increa-
ses the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at aqualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 261) as well as dis-
play messages (Y page 234).

sure on the rear wheels to improve driving
stability while braking. ADAPTIVE BRAKE

Slippery road surfaces
G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect,t he drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface.
If the vehicle threaten stoskid or cannot be
stopped when moving at low speed:
X Move the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
i For more information on driving with
snow chains, see (Y page 331). Driving systems
Cruise control
Important safety notes G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic condition sthat do not allow you to
drive at aconstant speed (e.g. heavy traffic
or winding roads). You may otherwise
cause an accident.
R on slippery roads. The drive wheels may
lose their grip when braking or accelerating
and the vehicle may skid.
R when there is low visibility, e.g. due to fog,
heavy rain or snow.
General notes Cruise control maintains
aconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2or 3in good time. By doing so, you will
make use of the braking effect of the engine.
This relieves the load on the brake system and
preventst he brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. You can
store any road speed above 30 km/h.

The following vehicle levels are possible:
R
normal
R raised: the vehicle is raised by about
25 mm when compared with the normal
level.
R lowered: the vehicle is lowered by about
10 mm when compared with the normal
level.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered" vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Comfort tuning"
(Y page 182) and then lock the vehicle
within 60 seconds of the engine being
switched off
R if you have selected "Sports tuning"
(Y page 182)
Setting the vehicle level G
WARNING
Make sure that nobody is in the vicinit yofthe
wheel housing or under the vehicle while low-
ering the vehicle when it is stationary. Other-
wise, limbs could become trapped.
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
Your selection remains stored even if you
remove the key from the ignition lock.
Setting raised level X
Start the engine. If indicator lamp
;is not lit:
X Press button :.

height is adjusted to raised level.
The Vehicle rising message appears in
the display.
The "Raised level" setting is cancelled if you:
R drive at aspeed over approximately
120 km/h
R drive for approximately three minutes at a
speed over 80 km/h.
The "Raised Level" remains saved when you
are not driving within these speed ranges.
Setting the norma llevel
X Start the engine.
If indicator lamp ;is lit:
X Press button :.
Indicator lamp ;goes out. The vehicle is
adjusted to normal level.
Suspension tuning General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each
wheel and depends on:
R
your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection ,i.e. sports or com-
fort
Your selection remains stored even if you
remove the key from the ignition lock. 182
