PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
:
and PASSENGER AIR BAG OFF 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
"Automatic front-passenger front airbag
deactivation system" (Y page 56) and on
"Children in the vehicle" (Y page 65).
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 56)
and on "Children in the vehicle"
(Y page 65).
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 56) as well
as on "Seat belts" (Y page 48) and "Air-
bags" (Y page 53). 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 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 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 48
Occupant safetySafety

Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or
enabled.
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 simultaneously for approx-
imately 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 air-
bag changes while the vehicle is in motion, an
airbag display message appears in the instru-
ment cluster (Y page 349). When the front-
passenger seat is occupied, always pay atten-
tion 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 jour-
ney.
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 possi-
ble
If the front passenger does not observe these
conditions, the automatic front-passenger
front airbag deactivation system may be influ-
enced, 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 dis-
abled by mistake as a result of these or similar actions. In this case, the PASSENGER AIR
BAG OFF indicator lamp lights up perma-
nently. The front-passenger front airbag doesnot 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. Occupant safety

fit the child restraint system to a suitable
rear seat.
R the front-passenger seat is occupied by a
person with a smaller build (e.g. a teenager
or small adult), either the PASSENGER AIR
BAG ON or PASSENGER AIR BAG OFF indi-
cator lamp lights up and remains lit after
the system self-test depending on the
result of the classification.
- if the PASSENGER AIR BAG ON indicator
lamp lights up, move the front-passenger
seat as far back as possible. Alterna-
tively, a person with a small build can sit on a rear seat.
- if the PASSENGER AIR BAG OFF indicator
lamp is lit, a person with a smaller build
should not use the front-passenger seat.
R the front-passenger seat is occupied by an
adult or a person with a build correspond-
ing to that of an adult, the PASSENGER AIR
BAG ON indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger front airbag
is enabled.
If children are travelling in the vehicle, be sure
to observe the notes on "Children in the vehi- cle" (Y page 65).
If the automatic front-passenger front airbag
deactivation system is malfunctioning, the
red 6 restraint system warning lamp in
the instrument cluster and the PASSENGER
AIR BAG OFF indicator lamp light up simulta-
neously. The front-passenger front airbag is
disabled in this case and does not deploy dur- ing an accident. Have the system checked as
soon as possible by qualified technicians.
Consult a Mercedes-Benz Service Centre. The
front-passenger seat should only be repaired at a Mercedes-Benz Service Centre.
If the front-passenger seat, the seat cover orthe seat cushion is damaged, have the nec-
essary repair work carried out at a Mercedes- Benz Service Centre.
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys-
tem which has been tested and approved by Mercedes-Benz in combination with the auto-
matic front-passenger front airbag deactiva-
tion system.
System self-test G
DANGER
If both the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not light up during the system self-test, the
system is malfunctioning. The front-
passenger front airbag might be triggered
unintentionally or might not be triggered at all in the event of an accident with high deceler-
ation. This poses an increased risk of injury or even fatal injury.
In this case the front-passenger seat may notbe used. Do not install a child restraint system
on the front-passenger seat. Have the auto-
matic front-passenger front airbag deactiva-
tion system checked and repaired immedi-
ately at a qualified specialist workshop. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp remains lit after the system self-test, the
front-passenger front airbag is disabled. It willnot be deployed in the event of an accident. In
this case, the front-passenger front airbag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front- passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. This poses an increased risk of injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R the classification of the person in the front-
passenger seat is correct and the front-
passenger front airbag is enabled or disa- Occupant safety

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.
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 volt- age.
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 opera-
tion. Do not allow bulbs to come into contact
with liquids.
Only replace the bulbs listed (Y page 146).
Have the bulbs that you cannot replace your- self replaced at a qualified specialist work-
shop.
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 LED headlamps: the front
and rear light clusters of your vehicle are
equipped with LED light bulbs. Do not replace
the bulbs yourself. Contact a qualified spe-
cialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Overview of bulb types
You can replace the following bulbs. The
details for the bulb type can be found in the
