Important safetynotes
GWARNING
If you do not have the prescribed service/
maintenanc ework or any required repairs
carried out, this can result in malfunctions or system failures. There is arisk of an accident.
Always have the prescribed service/mainte-
nanc ework as well as any required repairs
carried out at aqualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
checkt he vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardiz ethe operatin gsafety of
the vehicle. There is an increased risk of an
accidenta nd injury.
Never tamper with the wiring as well as elec-
tronic component sortheir software. You
should have all work to electrical and elec-
tronic equipment carried out at aqualified
specialist workshop.
!There is arisk of damage to the vehicle if:
Rthe vehicle becomes stuck ,e.g. on ahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or ahole in the road
Raheavy objec tstrikes the undercarriage or
parts of the chassis
In situation slike this, the body, the undercar-
riage, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catc hfire.
In such situations, have the vehicle checked
and repaired immediately at aqualified spe-
cialist workshop. If on continuin gyour jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aqualified spe-
cialist workshop.

If the front passenger does not observe these
conditions, OCS may produceafalse classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on avehicle armrest
Rsits in such away that their weight is raised
from the seat cushion
If you install achild 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. acushion. The entire base
of the child restraint system must always rest on
the seat cushio nofthe front-passenger seat.
The backrest of the forward-facing child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat.
The child restraint system must not touch the
roof or be subjected to aload by the head
restraint. Adjust the angle of the seat backrest
and the head restraint positiona ccordingly.
Only then can OCS be guaranteed to function
correctly. Alway sobserve the child restraint sys-
tem manufacturer's installation and operating
instructions.

event of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the status of the front-passenger front air bag changes whil ethe vehicle is in motion, an air bag
display messag eappears in the instrument clus-
ter (
Ypage 187). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status
of the front-passenger front air bag both before
and during the journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled.Itw illnot be deployed in the event of
an accident and cannot perform its intended
protective function. Aperson in the front-
passenger seat could then, for example ,come
into contact with the vehicle's interior, espe-
ciallyift he 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 ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.

GWARNING
If you secure achild in arearward-facing child
restraint system on the front-passenge rseat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenge rfront air bag
may deploy in an accident. The child coul dbe
struck by the air bag .This posesani ncreased
risk of injury or even fatal injury.
Make sure that the front-passenge rfront air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator lamp lights up, do not install arear-
ward-facing child restraint system on the front-
passenger seat. You can find more information
on OCS under "Problems with the Occupant
Classification System" (
Ypag e48).
GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenge rseat
and you position the front-passenge rseat too
close to the dashboard, in the event of an
accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG ON is lit up
This poses an increased risk of injury or even fatal injury.
Move the front-passenge rseat as far back as
possible.A lways make sure that the shoulder
belts trap is correctly routed from the vehicle
beltl oop to the shoulde rbeltg uide on the
child restraint system. The shoulde rbelts trap
must be routed forwards and downwards
from the beltl oop.Always observe the child
restraint system manufacturer's installation
instructions.
If OCS determines that:
Rthe front-passenge rseat is unoccupied ,the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and remains lit. This indicates that the front-
passenger front air bag is deactivated.
Rthe front-passenge
rseat is occupied by a
child of up to twelve months old, in astandard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenge rfront air bag is
deactivated.
But even in the case of atwelve-month-old
child ,inas tandard child restraint system, the
PASSENGER AIR BAG ON can light up perma-
nently after the system self-test. This indi-
cates that the front-passenge rfront air bag is
activated. The result of the classification is
dependent on, among other factors, the child
restraint system and the child's stature. Make
sure that the conditions for acorrect classi-
ficatio nare met. If the PASSENGER AIR BAG
OFF indicator lamp is still lit, do not install a
child restraint system on the front-passenger
seat.
Rthe front-passenge rseat is occupied by aper-
son of smaller stature (e.g. ateenage ror
smal ladult), either the PASSENGER AIR BAG
ON or PASSENGER AIR BAG OFF indicator
lamp lights up and remains lit after the system
self-test depending on the result of the clas-
sification.
-If the PASSENGER AIR BAG ON indicator
lamp lights up, move the front-passenger
seat as far back as possible.
-If the PASSENGER AIR BAG OFF indicator
lamp is lit, apersonofs maller stature
should not use the front-passenge rseat.
Rthe front-passenge rseat is occupied by an
adult or apersonofa dult stature, the
PASSENGER AIR BAG ON indicator lamp
lights up after the system self-test and

NECK-PRO head restraints
Important safety notes
GWARNING
The function of the head restraint may be
impaired if you:
Rattach object ssuch as coat hangers to the
head restraints, for example
Ruse head restraint covers
If you do so, the head restraint scannot fulfill
their intended protective function in the event of an accident.Ina ddition, objectsattached
to the head restraint scould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any object stothe head
restraint sand do not use head restraint cov-
ers.
Method of operation
NECK-PRO head restraint sreduce the likelihood
of head and chest injuries. The NECK-PRO head
restraint sonthe driver's and front-passenger
seats are moved forwards and upwards in the
event of arear-end collision of acertain severity.
This provides better head support.
If the NECK-PRO head restraint shave been trig-
gered in an accident,y ou must reset the NECK-
PRO head restraint sonthe driver’s and front-
passenger seat (
Ypage 51). Otherwise, the
additional protection will not be available in the event of another rear-end collision. You can rec-
ognize when NECK-PRO head restraint shave
been triggered by the fact that they have moved
forwards and can no longer be adjusted.
Mercedes-Benz recommends that you have the
NECK-PRO head restraint schecked for func-
tionality at aqualified specialist workshop after
ar ear-end collision.
