CockpitAt a glance

How the airbag system works is deter-
mined by the severity of the collision detec-
ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R
head-on collision
R side impact
R overturning
R rea rimpact
The rate of vehicle deceleratio noraccelera-
tion and the direction of the force are essen-
tially determined by:
R the distribution of forces during the colli-
sion
R the collisio nangle
R the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided
Factors which can only be see nand measured
after a collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indicatio nofairbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle parts such as longitudinal body
members are hit, and sufficien tdeceleration
occurs as a result. Airbags
Important safety notes G
WARNING
Airbags provide additional protection; they
are not, however, a substitute for seat belts. Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R
all vehicle occupants –inparticular, preg-
nant women – must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R always secure childre nless than 1.50mt all
and unde r12years of age in suitable child
restraint systems.
R all vehicle occupants must select a seat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the centre of the driver's airbag cover as
possible.
R move the front-passenger seat as far back
as possible. This is especially important if
you have secured a child in a child restraint
system on the front-passenger seat.
R vehicle occupants ―inparticular childre n―
must not lean their head in the area of the
window where the windowbag is deployed
R rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger airbag has
been disabled .Onthe front-passenger
seat, the front-passenger airbag is disabled
if a child restraint system with automatic
child seat recognition is fitted to the front-
passenger seat in a vehicle equipped with
automatic child seat recognition. The
4 PASSENGER AIRBAG OFF indicator
lamp must be continuously lit.
If the front-passenger seat of your vehicle
does not have automatic child seat recog-
nition, or your rearward-facing child
restraint system does not have automatic
child seat recognition, children must be
secured in a child restraint system on a
suitable seat in the rear. If you secure a
forward-facing child restraint system to the 40

EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 60). G
WARNING
If EBDh as 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 a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 254) as well as dis-
play messages (Y page 231).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE provides increased braking
safety. In addition to the braking function,
ADAPTIVE BRAKE also has the HOLD function

Important safety notes G
WARNING
The wiper arms could start moving and cause
an injury if you leave the windscreen wipers
switched on.
Remove the key from the ignition lock before
replacing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen/
rear window.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benzr ecommends that you have
the wiper blades changed at aqualified
specialist workshop. 120

WARNING
Very hot or very cold air can flow from the air
vents .This could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents. Keep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different area of the vehicle interior. General notes
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the bonnet free
of blockages, such as ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.
i If the automatic climate control con-
stantly differs from the set temperature or
if undesired draughts are noticeable, pro-
ceed as follows:
XOpen the side air vents
X Open the centre air vents
X Open the rear air vents
