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 running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
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 AIR BAG OFF indicator
lamp PASSENGER AIR BAG OFF indicator lamp
:is
part of the automatic child seat recognition on
the front-passenger seat.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front airbag is disabled.
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 child restraint system:
whether the front-passenger front airbag is
enabled or disabled depends on the installed
child restraint system, and the age and size of the child. Therefore, it is imperative to
observe the notes on "Children in the vehicle"
(Y page 47). There you will also find infor-
mation on rearward or forward-facing child
restraint systems on the front-passenger
seat.
R All other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. Be sure to
observe the notes on "Seat belts"
(Y page 37) and "Airbags" (Y page 41).
There you can also find information on the
correct seat position.
Observe the information on automatic child seat recognition in the front-passenger seat
(Y page 51). 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 for the front seat belts and
the outer seat belts in the rear Occupant safety

the front-passenger seat
The sensor system for the automatic child seat
recognition in the front-passenger seat detects
whether a special Mercedes-Benz child restraint
system with transponders has been fitted. In
this case, the PASSENGER AIR BAG OFF indica-
tor lamp lights up and remains lit. The front-
passenger front airbag is disabled.
i If the front-passenger front airbag is disa-
bled by the automatic child seat recognition,
the following remain enabled on the front-
passenger side:
R the sidebag
R the pelvisbag
R the windowbag
R the belt tensioner G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front airbag can
deploy in the event of an accident. The child could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag has been disabled. The PASSENGER AIR-
BAG OFF indicator lamp must be lit. 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.
In this case the front-passenger seat may not be used. You may only transport a child on the
front-passenger seat if they are seated in a
suitable rearward or forward-facing child
restraint system. Always observe the infor-
mation about suitable positioning of the child restraint system in this Owner's Manual as
well as the child restraint system manufac-
turer's installation instructions. G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
seat-belt extender to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and down- Children in the vehicle

Important safety notes
G
WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a bulb, you could burn yourself on these com-
ponents. There is a risk of injury.
Allow these components to cool down before replacing the bulb.
Vehicles with static LED headlamps:
Do not use a bulb that has been dropped or if its glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps designed
for that purpose. Only fit spare bulbs of the same
type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Only replace the bulbs listed (Y page 111).
Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop. Headlamps and lights are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times. Have
the headlamp setting checked regularly.
Vehicles with Intelligent Light System
The front and rear light clusters of your vehicle
are equipped with LED light bulbs. Do not
replace the bulbs yourself. Contact a qualified
specialist workshop, which has the necessary
specialist knowledge and tools to carry out the
work required.
Lamps are an important aspect of vehicle safety. You must therefore make sure that these func-
