!
Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have accessories retrofitted at a qualified
specialist workshop.
You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes. This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tyres, wheels and
accessories that have been specifically
approved for your vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the
use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or
independently approved by a testing centre.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R if other road users could be endangered
R if the emission or noise levels are adversely
affected
Always specify the vehicle identification num- ber (VIN) when ordering genuine Mercedes-
Benz parts (Y page 468). Owner's Manual
Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment
available for your vehicle at the time of pub-
lication of the Owner's Manual. Country-spe-
cific differences are possible. Note that your
vehicle may not be fitted with all features
described. This is also the case for systems
and functions relevant to safety. Therefore,
the equipment on your vehicle may differ from that in the descriptions and illustrations.
The original purchase contract documenta-
tion for your vehicle contains a list of all of the
systems in your vehicle.
Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and Service Booklet are important documents and should kept in the

as on "Seat belts" (Y
page 47) and "Air-
bags" (Y page 51). There you can also find
information on the correct seat position. Seat belts
Introduction A correctly fastened seatbelt is the most
effective means of restraining the movement
of vehicle occupants in the event of a collision or if the vehicle overturns. This reduces the
risk of vehicle occupants coming into contact
with parts of the vehicle interior or being
thrown from the vehicle. Additionally, the
seat belt helps to keep the vehicle occupant
in the best position in relation to the airbag.
The seat belt system consists of:
R seat belts
R belt tensioners for the front seat belts and
the outer seat belts in the rear
R belt force limiters for the front seat belts
and the outer seat belts in the rear
If the seat belt is pulled too quickly or sud-
denly from the belt outlet, the inertia reel will
lock. The belt strap cannot be pulled out fur-
ther.
In an impact, the belt tensioner tightens the
belt to pull it close to the body. It does not pull the vehicle occupants back in the direction of
the seat backrest.
The belt tensioner cannot compensate for the
seat position being incorrect or for a seat belt being routed or worn incorrectly.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is
reduced.
The belt force limiters on the front seats are
synchronised with the front airbags, which
take on a part of the deceleration force. This
reduces the forces to which vehicle occu-
pants are subjected during an accident.
! If the co-driver's seat is not occupied, do
not engage the seat belt tongue in the buckle on the co-driver's seat. Otherwise,
the belt tensioner could be triggered in the
event of an accident and would have to be
replaced.
Important safety notes G
WARNING
The seat belt cannot perform its intended pro- tective function if it is not fastened correctly. Also, an improperly fastened seat belt can
cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal.
Always make sure that all vehicle occupants
are wearing their seat belt properly and are
seated correctly. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. G
WARNING
Persons under 1.50 mtall cannot wear the
seat belts correctly without a suitable, addi-
tional restraint system. The seat belt cannot
perform its intended protective function if it is not fastened correctly. Also, an improperly
fastened seat belt can cause additional inju-
ries in the event of an accident, sudden brak-
ing or abrupt changes of direction. There is an increased risk of injury, possibly even fatal.
Secure persons less than 1.50 mtall in a suit-
able restraint system. Occupant safety
47Safety Z

If a rear seat passenger unfastens their seat
belt when travelling at a speed above
25 km/h, a short warning tone also sounds.
You can also cancel the rear seat belt status
indicator immediately (Y page 314).Airbags
Introduction The installation location of an airbag is iden-
tified by the AIRBAG symbol.
An airbag supplements a correctly worn seat
belt. It is not a replacement for the seat belt.
The airbag offers additional protection in
applicable accident situations.
Not all airbags are deployed in an accident.
The different airbag systems work independ-
ently of each other (Y page 60).
However, no system available today can com- pletely eliminate injuries and fatalities.
It is also not possible to completely rule out a
risk of injury caused by an airbag due to the
speed at which the airbag must be deployed.
Important safety notes G
WARNING
If you deviate from the correct seat position,
the airbag cannot perform its intended pro-
tective function and can even cause addi-
tional injuries when deployed. There is an
increased risk of serious or even fatal injuries.
In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seated correctly and maintain the fur-
thest possible distance from the airbags
R observe the following notes
Always ensure that there are no objects loca-
ted between the airbag and the vehicle occu-
pant.
R Adjust the seats properly before beginning
your journey. Always make sure that the seat is in an almost upright position. The
centre of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
R Only hold the steering wheel on the out-
side. This allows the airbag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air-
bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the
airbag.
R For this reason, always secure persons less
than 1.50 mtall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is travelling in your vehicle, also
observe the following notes:
R Always secure children under 12 years of
age and less than 1.50 mtall in suitable
child restraint systems.
R Child restraint systems should be fitted to
the rear seats.
R Only secure a child to the front-passenger
seat when the front-passenger front airbag
is disabled, and only then in a rearward-
facing child restraint system. If the
PASSENGER AIR BAG OFF indicator lamp is
permanently lit, the front-passenger front
airbag is disabled (Y page 46).
R Always observe the instructions and safety
notes on the automatic front-passenger
front airbag deactivation system
(Y page 54) and on "Children in the vehi-
cle" (Y page 63) in addition to the child
restraint system manufacturer's installa-
tion instructions. Occupant safety
51Safety Z

Objects in the vehicle interior may pre-
vent the airbag from functioning cor-
rectly. Before starting your journey and to
avoid risks resulting from the speed of the
airbag as it deploys, make sure that:
R there are no people, animals or objects
between the vehicle occupants and an air-
bag.
R there are no objects between the seat, door
and B-pillar.
R no hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
R no accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an airbag, e.g. to doors, side
windows, rear side trim or side walls.
R no heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place. G
WARNING
If you modify an airbag cover or affix objects
such as stickers to it, the airbag can no longer function correctly. There is an increased risk
of injury.
Never modify an airbag cover or affix objects
to it. G
WARNING
Sensors to control the airbags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ling, as well as damaged doors, can lead to the function of the sensors being impaired. The
airbags might therefore not function properly any more. Consequently, the airbags cannot
protect vehicle occupants as they are
designed to do. This poses an increased risk
of injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
elling carried out at a qualified specialist
workshop. Front airbags !
Do not place heavy objects on the front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied. In the event of an accident, the restraint
systems on the front-passenger side may
be triggered and have to be replaced. Driver's airbag
:deploys in front of the
steering wheel; front-passenger front air-
bag ;deploys in front of and above the glove
compartment.
When deployed on the front seats, the front
airbags offer additional protection for the
head and thorax.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
inform you about the status of the front-
passenger front airbag (Y page 46).
Front-passenger front airbag ;will only
deploy if:
R the automatic front-passenger front airbag
deactivation system has detected that the
front-passenger seat is occupied
(Y page 54). The PASSENGER AIR BAG
ON indicator lamp lights up (Y page 54)
R the restraint system predicts a high
severity of an accident 52
Occupant safetySafety

Driver's kneebag
Driver's kneebag
:deploys under the steer-
ing column. The driver's kneebag is triggered
together with the front airbag.
The driver's kneebag on the driver's seat
offers additional protection for the thighs,
knee and lower leg.
Sidebags G
WARNING
Unsuitable seat covers can obstruct or pre-
vent the deployment of the airbags integrated into the seats. Consequently, the airbags can-
not protect vehicle occupants as they are
designed to do. In addition, the function of the automatic front-passenger front airbag deac-
tivation system could be restricted. This
poses an increased risk of injury or even fatal
injury.
You should only use seat covers that have
been approved for the corresponding seats by Mercedes-Benz. Front sidebags
:and rear sidebags ;
deploy next to the outer bolster of the seat
backrest.
When deployed, the sidebag offers additional thorax protection. However, it does not pro-
tect the:
R head
R neck
R arms
In the event of a side impact, the sidebag is
deployed on the side on which the impact
occurs.
vehicles with the automatic front-passenger
front airbag deactivation system: the sidebag on the front-passenger side (front) deploys
under the following conditions:
R an occupant is detected on the front-
passenger seat or
R the belt tongue is engaged in the belt
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the sidebag on the front-passenger
side deploys if an appropriate accident situa- tion occurs. In this case, deployment is inde- pendent of whether the front-passenger seatis occupied or not.
Windowbags Windowbags
:are integrated into the side
of the roof frame and deployed in the area
from the A-pillar to the C-pillar.
When deployed, the windowbag enhances the
level of protection for the head. However, it
does not protect the chest or arms. Occupant safety

PRE-SAFE
®
(anticipatory occupant
protection)
Introduction PRE-SAFE
®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes !
Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R vehicles with the Driving Assistance pack-
age: when a driver assistance system inter-
venes powerfully or the radar sensor sys-
tem detects an imminent danger of colli-
sion in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains. The panorama sliding
sunroof is completely closed.
R vehicles with the memory function for the
front-passenger seat: the front-passenger seat is adjusted if it is in an unfavourable
position.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. You
will find information on the convenience func-
tion under "Belt adjustment" (Y page 50). PRE-SAFE
®
PLUS (anticipatory occu-
pant protection PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-
end collision is imminent. In certain hazard-
ous situations, PRE-SAFE ®
PLUS takes pre-
emptive measures to protect the vehicle
occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned when PRE-SAFE ®
PLUS intervenes.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and
there is a risk of a rear-end collision
PRE-SAFE ®
PLUS does not perform braking
actions while the vehicle is in motion or when
Parking Guidance is active. 62
