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 to
accommodate a person with disabilities, con- tact 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 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
effect belt tensioners or airbags, for example. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop.
PASSENGER AIRBAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp
:
and PASSENGER AIR BAG ON indicator
lamp ;are part of the automatic deactiva-
tion system of the front-passenger front air-
bag.
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.
Depending on the person in the front-
passenger seat, the front-passenger front air-
bag 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 imperative to observe the notes on the Occupant safety
43Safety Z

"Automatic front-passenger front airbag
deactivation system" (Y page 51) and on
"Children in the vehicle" (Y page 60).
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 51)
and on "Children in the vehicle"
(Y page 60).
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
"Automatic front-passenger front airbag
deactivation system" (Y page 51) as well
as on "Seat belts" (Y page 44) and "Air-
bags" (Y page 48). There you can also find
information on the correct seat position. Seat belts
Introduction A correctly worn seat belt is the most effec-
tive 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 ejected
from it. The seat belt also helps to keep the
vehicle occupants in the best position in rela-
tion to the airbag being deployed.
The seat belt system consists of:
R seat belts
R belt tensioners and belt force limiters If the seat belt is pulled quickly or sharply by
the seat-belt extender, the inertia reel locks.
The belt strap cannot be pulled out any fur-
ther.
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 vehi- cle occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct an incorrect seat position or correct the rout-
ing of a seat belt that is worn incorrectly.
When triggered, seat belt force limiters help
to reduce the peak force exerted by the seat
belt on the vehicle occupant.
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
occupants 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 44
Occupant safetySafety

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 backrestis 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.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the
vehicle:
R always secure the child in a child restraint
system suitable for this Mercedes-Benz
vehicle. The child restraint system must be appropriate to the age, weight and size of
the child.
R always observe the instructions and safety
notes on the automatic front-passenger
front airbag deactivation system
(Y page 51)
R always observe the instructions and safety
notes on "Children in the vehicle" in this
Owner's Manual (Y page 60) in addition
to the child restraint system manufactur-
er's installation instructions G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, have been modified, are
extremely dirty, bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R modifications have been made to the belt
tensioners, belt anchorages or inertia reels
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts can tear or fail, for example in the event of an accident. Modified
seat belt tensioners may be deployed unin-
tentionally or fail to be deployed when
required. There is an increased risk of injury,
possibly even fatal.
Never modify safety belts, seat belt tension-
ers, seat belt anchorages and inertia reels.
Ensure that seat belts are not damaged or
worn and are clean. After an accident, have
the seat belts checked immediately at a quali- fied specialist workshop.
Mercedes-Benz recommends that you only
use seat belts which have been approved
specifically for your vehicle by Mercedes-
Benz. Otherwise, your vehicle's general oper- ating permit could be invalidated.
Correct seat belt use Observe the safety notes on the seat belt
(Y
page 44).
All vehicle occupants must fasten their seat
belts correctly before starting the journey.
Also make sure during the journey, that all
vehicle occupants have their seat belt cor-
rectly fastened.
When fastening your seat belt, always make
sure that:
R the seat belt buckle tongue is only inserted
into the correct belt buckle for the corre-
sponding seat.
R the seat belt fits closely across your body.
Avoid wearing bulky clothing, e.g. a winter
coat. Occupant safety
45Safety Z

R
the seat belt is not twisted.
Only then can the forces produced during
an accident be distributed across the sur-
face of the seat belt.
R the shoulder section of the belt is routed
across the centre of your shoulder.
The shoulder section of the belt should not
touch the neck nor be routed under your
arm.
R the lap belt is fastened closely and routed
as low as possible across your lap, i.e.
across your hips.
The lap belt must always be routed across
the hip joints and never across your stom-
ach or abdomen. This is of particular impor-
tance for pregnant women. If necessary,
push the lap belt downwards into your pel-
vic area and pull it tight using the shoulder section of the belt.
R the seat belt is not routed across sharp-
edged, pointed or breakable objects.
Should you have such objects on or in your
clothing, e.g. pens, keys or spectacles,
stow these in a suitable place.
R only one person uses each seat belt at any
one time.
Infants and children must never travel sit-
ting on the lap of another vehicle occupant. In the event of an accident, they could be
crushed between vehicle occupant and
seat belt.
R never to secure objects with a seat belt if
the seat belt is also being used by a vehicle
occupant
Also make sure that there are never any
objects between a person and the seat, e.g. pillows.
Seat belts are solely intended to secure and
restrain vehicle occupants. When securing
objects, luggage or loads, always observe the instructions and safety notes in "Loading
guidelines" (Y page 316). Fastening seat belts Observe the safety notes on the seat belt
(Y
page 44) and the notes on correct use of
seat belts (Y page 45). G
WARNING
If the seat-belt extender extends during the
journey, the seat belt is not sitting correctly
across your body. The seat belt then cannot
perform its intended protective function.
There is an increased risk of injury, possibly
even fatal.
During a journey, make sure that the seat-belt extender is retracted. Seat-belt extender
The seat-belt extender for the driver and front passenger helps you fasten your seat belt.
Seat-belt extender =is extended when the
respective door is closed and the key is
turned to position 1or 2in the ignition lock. You can also extend seat-belt extender

with seat-belt extender button ?.46
Occupant safetySafety

The belt strap is tightened slightly when:
R with a retracted seat-belt extender, the
seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off using COMAND Online. Information
on activating and deactivating the seat-belt
adjustment function can be found in the Dig-
ital Owner's Manual.
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts. It may
light up continuously or flash. In addition, a
warning tone may sound.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belts.
i For more information on the
7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belt" (Y page 302).
Rear seat belt status indicator The rear seat belt status indicator is only
available for certain countries.
For approximately 30 seconds, the rear seat
belt status indicator informs you which rear
seat belt is not fastened.
The rear seat belt status indicator appears if:
R you drive off and reach a speed of approx-
imately 10 km/h
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion
R someone gets in or out of the vehicle and
you pull away again
You can also cancel the rear seat belt status
indicator immediately (Y page 266). 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 57).
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. 48
