Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupants coming into contact with parts of the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 46)
R adjust their seat and head restraint properly
(Y page 108).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (Y page 107).
You also have to make sure that an airbag can
inflate properly if deployed (Y page 48).
An airbag supplements a correctly fastened seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection of the seat belt is sufficient in an accident, the airbags are not deployed. In
the event of an accident, only the airbags that
increase protection in the relevant accident sit- uation are deployed. However, seat belts and
airbags generally do not protect against objects penetrating the vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tension-
ers and airbags" (Y page 55).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (Y page 58). Important safety notes

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 Occupant safety

Depending on the person in the front-passenger
seat, the front-passenger front airbag must
either be disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper- ative to observe the notes on the "Automatic
front-passenger front airbag deactivation sys-
tem" (Y page 51) and on "Children in the
vehicle" (Y page 58).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of
the child, the front-passenger front airbag is
either disabled or enabled. Therefore, it is
imperative to observe the notes on the "Auto- matic front-passenger front airbag deactiva-
tion system" (Y page 51) and on "Children in
the vehicle" (Y page 58).
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 notbe used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 51) as well as
on "Seat belts" (Y page 45) and "Airbags"
(Y page 48). There you can also find infor-
mation on the correct seat position. Seat belts
Introduction A correctly worn seat belt 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 vehi-
cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag being deployed. 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
If the seat belt is pulled quickly or sharply from
the belt outlet, the inertia reel locks. The belt
strap cannot be pulled out any further.
The belt tensioner tightens the seat belt in the
event of a collision so that it fits tightly across
your body. However, it does not pull the vehicle
occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct an
incorrect seat position or correct the routing of a seat belt that is 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 can
reduce the forces to which the 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 ten-
sioner 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 Occupant safety

The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled.
X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front airbag:
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears in the instrument clus-
ter (Y page 311). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the front-passenger front airbag both before
and during the journey.
If a person sits in the passenger seat, they must
be:
R seated with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag does not then
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install a rear- ward-facing child restraint system on the front-
passenger seat. Further information can be
found under "Problems with the automatic front-
passenger front airbag deactivation system"
(Y page 55). 52
Occupant safetySafety

Using the radar sensor system, PRE-SAFE
®
PLUS is able to detect that a head-on or rear-end
collision is imminent. In certain hazardous sit-
uations, 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 before the intervention
of PRE-SAFE ®
PLUS.
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
When driving, or when parking or exiting a park- ing space with assistance from Active Parking
Assist, PRE-SAFE ®
PLUS will not apply the
brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta-
tionary
- the seat belts are pre-tensioned.
The PRE-SAFE ®
PLUS braking application is can-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if DISTRONIC PLUS indicates an intention to
pull away
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. Automatic measures after an acci-
dent
Immediately after an accident, the following
measures may be implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with a memory function: the electri-
cally adjustable steering wheel is raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call
R vehicles with the hybrid drive system: the
hybrid system and the high-voltage electrical
system are deactivated Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children
are generally better protected there.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
R always pay attention to the instructions and
safety notes on the automatic front-
passenger front airbag deactivation system
(Y page 51). 58
Children in the vehicleSafety

G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts could become very hot.
Children could be suffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is a risk of injury.
If you and your child leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has
been exposed to direct sunlight, leave it to
cool down before securing the child in it.
Never leave children unattended in the vehi-
cle.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(Y page 45) and the information on the correct
use of the seat belt (Y page 46). Child restraint system
If you fit a rearward-facing child restraint system
to the centre rear seat, the rear arm rest must be folded back as far as possible.
Observe the instructions for correct use of the
child restraint system (Y page 63).
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint system recommended by Mercedes-Benz
(Y page 67). G
WARNING
If the child restraint system is incorrectly fit-
ted on the seat position suitable for this pur-
pose, it cannot perform its intended protec-
tive function. In the event of an accident,
sharp braking or a sudden change in direction, the child may not be held securely. There is an
increased risk of serious or even fatal injuries.
Observe the manufacturer's installation
instructions and the correct use for the child
restraint system. Make sure that the entire
surface of the child restraint system is resting
on the seat surface. Never place objects
under or behind the child restraint system,
e.g. cushions. Only use child restraint sys-
tems with the original cover designed for
them. Only replace damaged covers with gen- uine covers. G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always fit child restraint systems properly,
even if they are not being used. Make sure
that you observe the child restraint system
manufacturer's installation instructions.

of injury even further. If the child restraint sys-
tem is fitted with a Top Tether belt, this should
always be used.
Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a Top Tether belt. Adjust the rear seat backr-
ests so that they are positioned upright.
Make sure that the backrest in the rear com-
partment engages fully. To do so, pull firmly on
the seat backrest.
