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.

Important safety notes
Seat belts, together with the Supplemental
Restraint System – SRS (Y page 47), 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 104).
R the seat belt has been fastened properly
(Y page 55).
R the airbags can inflate unrestricted if
deployed (Y page 48).
R the steering wheel is adjusted properly
(Y page 104).
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. 46
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 59).
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. Otherwise, the sidebags cannot
deploy correctly and would fail to provide the 50

The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. On vehicles with a luxury multi-
function steering wheel (12 buttons), you can
switch the seat-belt adjustment on and off
using the on-board computer (Y page 244).

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.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving. G
WARNING
Do not depress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect .You
might otherwise not be able to stop the vehi-
cle in time and could cause an accident.
Depress the brake pedal firmly and smoothly. BAS (Brake Assist)
i Observe the "Important safety notes" sec-
tion (Y page 72). BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. G
WARNING
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. BAS PLUS (Brake Assist System Plus)
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 72).
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor system to evaluate
the traffic situation.
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
Should you approach an obstacle and BAS
PLUS has detected a ris kofcollision, BAS
PLUS calculates the braking force necessary
to avoid a rear-end collision. Should you apply
the brakes forcefully, BAS PLUS can auto-
matically increase the braking force to a level
suitable for the traffic conditions.
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection Driving safety systems

®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the trailer from swervin gand will thus be
unable to reduce the ris kofanaccident. Trail-
ers with a high centre of gravity can tip over
before ESP ®
can detect this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function. EBD (electronic brake forc
edistribu-
tion)
i Observe the "Importan tsafety notes" sec-
tion (Y page 72).
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 293) as well as display mes-
sages (Y page 251) (4-button multifunc-
tion steering wheel) and ( Ypage 257) (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 193) and
hill start assist (Y page 156). For further
information, see Driving tips (Y page 175). PRE-SAFE

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

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

WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people in need of special assistance if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally
injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuing people from outside the vehi-
cle is difficult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the vehicle has been locked from the outside with
the key. G
WARNING
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. G
