!
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 470). Owner's Manual

General notes
Hybrid technology combines a fuel-efficient
internal combustion engine with a powerful
electric motor. Important safety notes
Danger of electric shock G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. When towing a vehicle after an accident, be
sure to observe the following sections:
R Transporting the vehicle (Y page 427)
R Towing the vehicle with the rear axle raised
(Y page 426)
R Towing the vehicle with both axles on the
ground (Y page 427)
Read the safety instructions on towing and
tow-starting (Y page 424). All components of the hybrid system are
marked with yellow warning stickers that
warn you of the danger of high voltage. The
cables of the vehicle's high-voltage electrical
system are orange in colour.
The ignition must be switched off when car-
rying out general tasks, such as changing
bulbs or checking the coolant level.
Automatic deactivation of the hybrid
system G
DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. In addition, the vehicle's high-voltage electri-
cal system may not be deactivated as inten-
ded in the event of an accident. Touching
damaged components of the vehicle's high-
voltage electrical system could result in an
electric shock. There is an increased risk of
injury, possibly even fatal. 42
Hybrid vehiclesSafety

The restraint system includes:
R seat belt system
R airbags
R child restraint system
R child seat securing systems
The components of the restraint system are
complementary. They can offer maximum
protection only when all vehicle occupants:
R secure their seat belts correctly
(Y page 48)
R adjust the seat and head restraints prop-
erly (Y page 119)
As the driver, you must also make sure that
the steering wheel is adjusted correctly.
Observe the information on the correct driv-
er's seat position (Y page 118).
Additionally, you must make sure that the air- bag can inflate without restriction if deployed
(Y page 51).
An airbag is supplementary to a correctly fas-
tened seatbelt. An airbag, as an additional
safety device, provides greater protection for vehicle occupants in an accident situation. If
the seat belts offer sufficient protection in the
event of an accident, for example, the airbags
will not be deployed. Also, only the airbags
which are deemed to offer protection in the
corresponding accident situation are
deployed. However, seat belts and airbags
generally do not protect against objects pen-
etrating the vehicle from the outside.
Information on how the restraint system
operates can be found in "Deployment of the seat belt tensioner and airbags"
(Y page 60).
See "Children in the vehicle" (Y page 63) for
further information on infants and children
travelling in the vehicle as well as on child
restraint systems. Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an airbag system
for a person with physical disabilities, contact a Mercedes-Benz Service Centre for details. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew seconds after the vehicle is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with
the engine running
R lights up again while the engine is running
All vehicles, except hybrid vehicles: G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can

"Children in the vehicle" (Y page 63).
R Children in a forward-facing child
restraint system: depending on the instal-
led child restraint system and the age and
size of the child, the front-passenger front
airbag is either disabled or enabled. There-
fore, it is imperative to observe the notes
on the "Automatic front-passenger front
airbag deactivation system" (Y page 54)
and on "Children in the vehicle"
(Y page 63).
R All other persons: the PASSENGER AIR
BAG ON indicator lamp must be lit. The
front-passenger front airbag is enabled.
Depending on the build of the person on the front-passenger seat, the PASSENGER AIR
BAG OFF indicator lamp may light up. The
front-passenger front airbag is disabled. It
will then not be deployed in the event of an
accident. In this case, the front-passenger
seat should not be used.
It is imperative to observe the notes on the

deactivation system" (Y
page 54) as well
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. Occupant safety

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 316).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 Always secure persons less than 1.50 mtall
in suitable restraint systems. Up to this
height, the seat belt cannot be worn cor-
rectly.
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 m tall 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
