There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop.
Hybrid vehicles: G
DANGER
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. In addition, the vehicle's high-voltage electri-
cal system may not be deactivated as inten-
ded in the event of an accident. Touching
damaged components of the vehicle's high-
voltage electrical system could result in an
electric shock. There is an increased risk of
injury, possibly even fatal.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. After an accident, immediately
switch the ignition off and remove the key
from the ignition lock. PASSENGER AIRBAG indicator lamp

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

front-passenger front airbag is disabled.
Always observe the information on the
"Automatic front-passenger front airbag
deactivation system" (Y page 54) and on
"Children in the vehicle" (Y page 63).
R Children in a forward-facing child
restraint system: depending on the instal-
led child restraint system, the age and size of the child the front-passenger front airbag
is either disabled or enabled. Therefore,
always observe the information on the
"Automatic front-passenger front airbag
deactivation system" (Y page 54) and on
"Children in the vehicle" (Y page 63).
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.
Always observe the information on the
"Automatic front-passenger front airbag
deactivation system" (Y page 54) as well46
Occupant safetySafety

In the event of a side impact, the windowbag
is deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a windowbag may be deployed in
other accident situations (Y page 60).Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system
on the front-passenger seat, the automatic
front-passenger front airbag deactivation sys- tem categorises the person in the front-
passenger seat. Depending on that result, the
front-passenger front airbag is either enabled or disabled. If a rearward-facing child
restraint system is fitted to the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp must light up after the
system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the windowbag
R the seat belt tensioner
Make sure that your vehicle is equipped with
the automatic front-passenger front airbag
deactivation system (Y page 66). If this is
not the case, always fit the child restraint sys- tem on a suitable rear seat (Y page 68).
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. Fully retract the seat
cushion length. The entire base of the child
restraint system must always rest on the seat cushion of the front-passenger seat. The
backrest of the forwards-facing child restraint
system must, as far as possible, be resting on the backrest of the front-passenger seat. The child restraint system must not touch the roof
or be put under strain by the head restraint.
Adjust the angle of the seat backrest and the
head restraint position accordingly. Only then is the correct function of the automatic front- passenger front airbag deactivation system
guaranteed. Always observe the information
on suitable positioning of the child restraint
system (Y page 68) in addition to the child
restraint system manufacturer's installation
instructions.
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

in the case of an accident, all deployment 54
Occupant safetySafety

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 328). 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 there is no child restraint system fitted to
the front-passenger seat, the front-passenger
must sit:
R 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 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 childcould 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 rearward-facing child restraint system on
the front-passenger seat. Further information can be found under "Problems with the auto-matic front-passenger front airbag deactiva-
tion system" (Y page 59). Occupant safety
55Safety Z

always rest on the seat cushion of the front-
passenger seat. The backrest of the forwards- facing child restraint system must, as far as
possible, be resting on the backrest of the
rear reclining seat. Always comply with the
child restraint system manufacturer's instal-
lation instructions.
After the system self-test, the PASSENGER
AIR BAG OFF or PASSENGER AIR BAG ON
indicator lamp display the status of the front- passenger front airbag (Y page 54).
Further information can be found under
"Problems with the automatic front-
passenger front airbag deactivation system"

restraint system 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. Observe the lock verificationindicator. Adjust the rear seat backrests so
that they are in an upright position.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction display in the instrument cluster. A warning
tone also sounds.

General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. 66
