General notes

Restraint system
Protection provided by the restraint system
The restraint system includes the following com-
ponents:
=
Seat belt sy
stem
= Airbags
= Child restraint system
= Child seat anchors
The restraint system can help prevent the vehicle
occupants from coming into contact with parts of
the vehicle interior in the event of an accident. In
the event of an accident, the restraint system can
also reduce the forces to which the vehicle occu-
pants are subjected.
A seat belt can only provide the best level of pro-
tection if it is worn correctly. Depending on the
detected accident situation, seat belt tensioners
and/or airbags supplement the protection oMered
by a correctly worn seat belt. Seat belt tensioners
and/or airbags are not deployed in every acci-
dent. In order for the restraint system to provide the
int

ended level of protection, each vehicle occu-
pant must observe the following information:
= Fasten seat belts correctly.
= Sit in an almost upright seat position with their
back against the seat backrest.
= Sit with their feet resting on the Ooor, if possi-
ble.
= Always secure persons under 1.50 m tall in an
additional restraint system suitable for
Mercedes-Benz vehicles.
However, no system available today can com-
pletely eliminate injuries and fatalities in every
accident situation. In particular, the seat belt and
airbag generally do not protect against objects
penetrating the vehicle from the outside. It is also
not possible to completely rule out the risk of
injury caused by the airbag deploying. Limitations of the protection provided by the
r
estraint system &
WARNING Risk of injur
y or death due to
modiNcations to the restraint system
Vehicle occupants may no longer be protected
as int
ended if alterations are made to the
restraint system. 
Never alter the parts of the restraint sys-
t
em. 
Never tamper with the wiring or any elec-
tr
onic component parts or their sos-
ware. If it is necessary to modify the vehicle to accom-
modat
e a person with disabilities, contact a quali-
Ned specialist workshop.
Mercedes-Benz recommends that you use driving
aids which have been approved for your vehicle by
Mercedes-Benz. Occupant safety

Restraint system functionality
When the vehicle is switched on, a self-test is per-
f
ormed, during which the 6 restraint system
warning lamp lights up. It goes out no later than a
few seconds aser the vehicle is started. The com-
ponents of the restraint system are then func-
tional. Malfunctioning restraint system
A malfunction has occurred in the restraint sys-
t

em if:
= the 6 restraint system warning lamp does
not light up when the vehicle is switched on
= the 6 restraint system warning lamp lights
up continuously or repeatedly during a journey
All vehicles, except plug-in hybrid: &
WARNING Risk of injur
y due to malfunc-
tions in the restraint system
Components in the restraint system may be
activ
ated unintentionally or not deploy as
intended in an accident. 
Have the restraint system checked and
r

epaired immediately at a qualiNed spe-
cialist workshop. Plug-in hybrid:

DANGER Risk of f
atal injuries due to
restraint system malfunctions
Components in the restraint system may be
activ
ated unintentionally or not deploy as plan-
ned in an accident. In the event of an acci-
dent, the high-voltage on-board electrical sys-
tem may not be deactivated as intended.
You may suMer an electric shock if you touch
the damaged components of the high-voltage
on-board electrical system. 
Have the restraint system checked and
r

epaired immediately at a qualiNed spe-
cialist workshop. 
Aser an accident, switc
h oM the vehicle
immediately. Function of the restraint system in an accident
How the restraint system works depends on the
se

verity of the impact detected and the apparent
type of accident:
= Frontal impact
= Rear impact
= Side impact
= Rollover
The activation thresholds for the components of
the restraint system are determined based on the
evaluation of the sensor values measured at vari-
ous points in the vehicle. This process is pre-emp-
tive in nature. The triggering/deployment of the
components of the restraint system must take
place in good time at the start of the collision.
Factors which can only be seen and measured
aser a collision has occurred cannot play a deci-
sive role in airbag deployment. Nor do they pro-
vide an indication of airbag deployment.
The vehicle may be deformed signiNcantly without
an airbag being deployed. This is the case if only
parts which are relatively easily deformed are
aMected and the rate of vehicle deceleration is 48
Occupant safety

not high. Conversely, an airbag may be deployed
e
ven though the vehicle suMers only minor defor-
mation. If very rigid vehicle parts such as longitu-
dinal members are hit, this may result in suP-
ciently high levels of vehicle deceleration.
Depending on the detected deployment situation,
the components of the restraint system can be
activated or deployed independently of each
other:
= Seat belt tensioner: frontal impact, rear
impact, side impact, rollover
= Driver's airbag, front passenger airbag: frontal
impact
= Knee airbag: frontal impact
= Side airbag: side impact
= Window airbag: side impact, rollover, frontal
impact
= PRE-SAFE n
Impulse Side: side impact
Only when the PASSENGER AIR BAG OFF indica-
tor lamp is oM can the front passenger airbag
deploy in the event of an accident. If the front
passenger seat is occupied, make sure, both
before and during the journey, that the status of the front passenger airbag is correct
(
 pag
e 58). &
WARNING Risk of bur
ns from hot airbag
components
The airbag parts are hot aser an airbag has
been deplo
yed. 
Do not touch the airbag parts. 
Have a deployed airbag replaced at a
q
ualiNed specialist workshop as soon as
possible. Mercedes-Benz recommends that you have the
v

ehicle towed to a qualiNed specialist workshop
aser an accident. Take this into account, particu-
larly if a seat belt tensioner is triggered or an air-
bag deployed.
If the seat belt tensioners are triggered or an air-
bag is deplo
yed, you will hear a bang, and a small
amount of powder may also be released:
= The bang will not generally aMect your hearing.
= In general, the powder released is not hazard-
ous to health but may cause short-term breathing diPculties
t
o persons suMering from
asthma or other pulmonary conditions.
Provided it is safe to do so, leave the vehicle
immediately or open the window in order to
prevent breathing diPculties. Seat belts
Protection provided by the seat belt
Always fasten your seat belt correctly before
s

tarting a journey. A seat belt can only provide
the best level of protection if it is worn correctly. &
WARNING Risk of injur
y or death due to
incorrectly fastened seat belt
If the seat belt is not worn correctly, it cannot
per
form its intended protective function.
In addition, an incorrectly fastened seat belt
can also cause injuries, for example, in the
event of an accident or when braking or
changing direction suddenly. Occupant safety
49


Always ensure that all vehicle occupants
ha
ve their seat belts fastened correctly
and are sitting properly. Always observe the instructions about the correct
dr

iver's seat position and adjusting the seat
(  page 109).
In order for the correctly worn seat belt to provide
the intended level of protection, each vehicle
occupant must observe the following information:
= The seat belt must not be twisted and must Nt
tightly and snugly across the body.
= The seat belt must be routed across the
centre of the shoulder and as low down across
the hips as possible.
= The shoulder section of the seat belt should
not touch your neck nor be routed under your
arm or behind your back.
= Avoid wearing bulky clothing, e.g. a winter
coat.
= Push the lap belt down as far as possible
across your hips and pull tight with the shoul-
der section of the belt. Never route the lap
belt across your abdomen. Pregnant women must also take particular
car

e with this.
= Never route the seat belt across sharp, poin-
ted, abrasive or fragile objects.
= Only one person should use each seat belt at
any one time.
= Never secure objects with a seat belt if the
seat belt is also being used by one of the vehi-
cle's occupants.
Also ensure that no objects, e.g. a cushion,
are ever placed between a person and the
seat.
If children are travelling in the vehicle, be sure to
observe the instructions and safety notes on
"Children in the vehicle" ( page 63).
Always observe the instructions for loading the
vehicle when securing objects, luggage or loads
( page 127). Limitations of the protection provided by the seat
belt
&
WARNING Risk of injur
y or death due to
incorrect seat position
The seat belt will not oMer t
he intended level
of protection if you have not moved the seat
backrest to an almost vertical position.
In particular, you may slip under the seatbelt
and injure yourself. 
Adjust the seat properly before begin-
ning y

our journey. 
Always ensure that the seat backrest is
in an almos

t vertical position and that
the shoulder section of your seat belt is
routed across the centre of your shoul-
der. 50

&
WARNING Risk of injur y or death when
additional restraint systems are not used
for persons with a smaller stature
Persons under 1.50 m tall cannot wear the
seat belt cor
rectly without a suitable addi-
tional restraint system. 
Always secure persons under 1.50 m tall
in a suit
able restraint system. &
WARNING Risk of injur
y or death due to
damaged or modiNed seat belts
Seat belts cannot provide protection in the fol-
lo
wing situations:
= the seat belt is damaged, has been modi-
Ned, is extremely dirty, bleached or dyed
= the seat belt buckle is damaged or
extremely dirty
= modiNcations have been made to the seat
belt tensioner, seat belt anchorage or seat
belt retractor
Seat belts may sustain non-visible damage in
an accident, e.g. due to glass splinters. ModiNed
or damag
ed seat belts could tear or
fail in the event of an accident, for example.
ModiNed seat belt tensioners could acciden-
tally trigger or fail to function as intended. 
Never modify the seat belt system, for
e

xample the seat belt, seat belt buckle,
seat belt tensioner, seat belt anchorage
and seat belt retractor. 
Make sure that the seat belts are undam-
ag

ed, not worn and clean. 
Always have the seat belts checked
immediat
ely aser an accident at a quali-
Ned specialist workshop. Mercedes-Benz recommends that you use seat
belts whic

h have been approved for your vehicle
by Mercedes-Benz. &
WARNING Risk of injur
y or death from
deployed pyrotechnic seat belt tensioners
Pyrotechnic seat belt tensioners that have
been deplo
yed are no longer operational and
are unable to perform their intended protec-
tive function. 
Therefore, have deployed pyrotechnic
seat belt t

ensioners immediately
replaced at a qualiNed specialist work-
shop. Mercedes-Benz recommends that you have the
v

ehicle towed to a qualiNed specialist workshop
aser an accident.
* NOTE Damag
e caused by trapping the
seat belt If an unused seat belt is not fully retracted, it
ma

y become trapped in the door or in the seat
mechanism. 
Always ensure that an unused seat belt
is full

y retracted. Fastening and adjusting seat belts
If the seat belt is pulled quickly or sharply, the
seat belt r
etractor locks. The seat belt strap can-
not be pulled out any further. Occupant safety
