Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 26).Occupant safety
Important safety notes
Seat belts, together with the Supplemental
Restraint System – SRS (Y page 45), are
complementary, co-ordinated restrain tsys-
tems .They reduce the risk of injury in spe-
cific, pre-defined types of accident situations
and thereby increase occupant safety. How-
ever, seat belts and airbags generally do not
protect against objects penetrating the vehi-
cle from the outside.
To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R the seat and head restraint are adjusted
properly (Y page 96).
R the seat belt has been fastened properly
(Y page 53).
R the airbags can inflate unrestricted if
deployed (Y page 46).
R the steering wheel is adjusted properly
(Y page 96).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt. As
such, they are only an additional restraint
system which complements, but does not
replace, the seat belt. All vehicle occupants must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. The airbags are not deployed in all
types of accidents. For example, if the pro-
tective capacity of correctly fastened seat
belts is not increased by deploying the air-
bags, the airbags will not deploy.A
irbag
deploymen tonly provides increased pro-
tection if the seat belt is worn correctly
because:
R the sea tbelt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag.
R in a head-on collision, for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact. It can thus reduce the risk of
injury.
In accidents in which an airbag is deployed,
it provides increased protection only if the
seat belt is worn correctly. G
WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. The workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop. 44
Occupant safetySafety

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
syste mont he front-passenger seat.
R vehicle occupants –inparticular, children
–m ust no tlean their heads into the area of
the window in which the sidebag/window-
bag 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. On the front-passenger
seat, the front-passenger airbag is disabled
if a child restraint system with a trans-
ponder for automatic child seat recognition
is fitted to the front-passenger seat in a
vehicle equipped with automatic child seat
recognition. The 4PASSENGER 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
front-passenger seat, you must move the
front-passenger seat as far back as possi-
ble.
R make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger airbag, partic-
ularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel. R
do not lean on the doors from inside the
vehicle.
R make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
backrest and the door.
R do not hang any hard objects, for example,
coat hangers, on the grab handles or coat
hooks.
R do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
Airbag functionality can only be assured if the
following parts are not covered and no badges
or stickers are attached to them:
R padded steering wheel boss
R kneebag cover below the steering column
R front-passenger airbag cover
R outer side of fron tseat bolsters
R side trim next to the rear seat backrest
R roof frame cover between the fron tA-pillar
and the C-pillar in the rear compartment G
WARNING
As mall amount of powder is released when
an airbag is deployed. The powder could
cause short-term breathing difficulties in peo-
ple with asthma or other respiratory prob-
lems.
In order to prevent breathing difficulties, you
should leave the vehicle as soon as it is safe
to do so. You can also open the window to
allow fresh air to enter the interior. The pow-
der does not constitute ahealth hazard and
does not indicate that there is a fire in the
vehicle. Occupant safety

WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at a qualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
Fron tairbags The fron
tairbags increase protection for the
driver's and front-passenger's head and
chest. Driver's airbag
:deploys in front of the
steering wheel; front-passenger airbag ;
deploys in front of and above the glove com-
partment.
They are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deploymen tcan offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbag sinthe vehi-
cle
Front-passenger airbag ;is only activated if
the system determines that the front-
passenger seat is occupied. The 4
PASSENGER AIRBAG OFF indicator lamp on
the centre console is not lit (Y page 57).
This means that a child restraint system with- out automatic child seat recognition has been
fitted or that a child restraint system with
automatic child seat recognition is incorrectly
fitted.
!
Do not place heavy objects on the front-
passenger seat. The system may then
detect that the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced.
Driver's kneebag i
The driver's kneebag is only available in
certain countries.
The driver's kneebag increases protection of
the driver against:
R knee injuries
R thigh injuries
R lower leg injuries Driver's kneebag
:is always deployed along
with the driver's airbag and inflates under-
neath the steering column.
Sidebags G
WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat covers must have a special tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and 48

The rear seat belts are equipped with a child
seat lock (Y page 56). If you pull out the seat
belt fully and then allow the inertia reel to
retract it, the child-seat lock is activated. To
deactivate the child seat lock, unfasten the
seat belt and guide the belt tongue to the belt
sash guide.
For more information about releasing the seat
belt with release button ?, see "Releasing
seat belts" (Y page 53). Seat belt adjustment The seat-belt adjustment function adjusts the
driver's and front-passenger seat belt to the
upper body of the occupants.
The belt strap is tightened slightly when:
R
you engage the belt tongue in the belt
buckle and you then turn the key to position

i If you have guided the seat belt back, it is
turned 180 °. This is necessary in order to
guarantee that the seat belt is not twisted
and that it is routed correctly when the belt
is fastened.
! Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.

Driving safety systems overview
In this section, you will find informatio nabout
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
R BAS (Brake AssistSystem)
R BAS PLUS ( BrakeAssist System Plus*)
R Adaptive brake lamps
R ESP ®
(Electronic StabilityProgram)
R EBD ( electronic brake force distribution)
R ADAPTIVE BRAKE
R PRE-SAFE ®
Brake Important safety notes
If you fail to adapt your driving style, the driv-
ing safety systems can neither reduce the risk
of acciden tnor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions, as
well as the traffic conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
i Please note that the driving safety sys-
tems described only work as effectively as
possible when there is adequate contact
between the tyres and the road surface.
Pay particular attention to the information regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and
tyres" section (Y
page 336).
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-lock Braking System)
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 65).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
WARNING
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations. Driving safety systems

is
deactivated or disabled because of a mal-
function. EBD (electronic brake force distribu-
tion)
i Observe the "Importan tsafety notes" sec-
tion (Y page 65).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EB Dhas malfunctioned, the braking system
remains available with full brake boosting
effect .However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefore adapt your
driving style to the different handling charac-
teristics.
X Observe the notes on warning and indicator
lamps (Y page 275) as well as display mes-
sages (Y page 235) (4-button multifunc-
tion steering wheel) and ( Ypage 240) (12-
button multifunction steering wheel). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 177) and
hill start assist (Y page 140). For further
information, see Driving tips (Y page 159).PRE-SAFE
®
Brake
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 65). PRE-SAFE
®
Brake can help you to minimise
the risk of a frontal collision with a vehicle
ahead or reduce the effect sofsuch a colli-
sion. If PRE-SAFE ®
Brake has detected a risk
of collision, you will be warned visually and
acoustically as well as by automatic braking.
PRE-SAFE ®
Brake cannot prevent a collision
without your intervention.
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in fron tis too short for
the speed at which you are travelling. The
· distance warning lamp then lights up
in the instrument cluster.
R you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ®
Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R brake the vehicle automatically from a
speed of up to approximately 200 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) (Y page 50)
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. To end this,
you can either depress the accelerator pedal
further, activate kickdown or release the
brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you drive slower than approximately
15 km/h.
R you manoeuvre to avoid the obstacle. Driving safety systems
