WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not be trig-
gered as intended in the event of an acci-
dent. This may affect the Emergency Ten-
sioning Devices or air bags, for example.
There is a risk of injury.
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 Occupant Classification System
(OCS).
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the co-driver's
air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
R is lit, the co-driver's air bag is deactivated.
It will not be deployed in the event of an
accident.
R is not lit , the co-driver's air bag is enabled.
If, in the event of an accident, all deploy-
ment criteria are met, the co-driver's air bag
is deployed. Depending on the person in the co-driver's
seat, the co-driver's air bag must be either
deactivated 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 co-driver's air bag is enabled or
deactivated depends on the installed child
restraint system and the age and size of the
child. It is thus essential to comply with the
instructions on the "Occupant Classification
System (OCS)" ( Y page
54) and "Children
in the vehicle" ( Y page 60). Information is
also included here on rearward or forward-
facing child restraint systems on the co-driv-
er's seat.
R All other persons: depending on the classi-
fication of the person in the co-driver's seat,
the co-driver's air bag must be either ena-
bled or deactivated (Y page 54). Be sure to observe the notes on "Seat belts"
( Y page 47) and "Air bags" (Y page 51).
Information is also included here on the cor-
rect seating position. Seat belts
Introduction A correctly fastened seat belt is the most
effective means of limiting the movement of a
vehicle occupant during a collision or in the
event that the vehicle overturns. This reduces
the risk of vehicle occupants coming into con-
tact with parts of the vehicle interior or being
ejected from it. Furthermore, the seat belt
helps to keep the vehicle occupant in the best
position in relation to a deployed air bag.
The seat belt system consists of:
R seat belts
R Emergency Tensioning Devices for the front
seat belts
The seat belt system includes a belt force
limiter for the respective seat if the vehicle
is equipped with a front air bag.
If the seat belt is pulled quickly or suddenly
from the belt outlet, the inertia reel locks. The
belt strap cannot be pulled out further.
In an impact, the Emergency Tensioning
Device tightens the belt to pull it close to the
body. It does not pull the vehicle occupant Occupant safety

Safety Z

Fastening and adjusting seat belts
Observe the safety notes on seat belts
(Y page
48) and the notes on the correct use
of the seat belt (Y page 49). Basic diagram
X Adjust the seat (Y page
87).
The seat backrest must be in an almost ver-
tical position.
X Pull the seat belt out smoothly from the belt
outlet and engage belt tongue ; into belt
buckle :.
The shoulder section of the belt must
always be routed across the center of the
shoulder. If necessary, adjust the belt out-
let.
X If necessary, pull upwards on the seat belt
in front of your chest so that the belt sits
tightly across your body.
The shoulder section of the belt must always
be routed across the center of the shoulder. If
necessary, adjust the belt outlet. X To raise: slide the belt outlet upwards.
The belt outlet engages in a number of dif-
ferent positions.
X To lower: slide the belt outlet downwards
while pressing belt outlet release =.
X Let go of belt outlet release = in the
desired position and make sure that the belt
outlet engages.
All seat belts in the vehicle, with the exception
of the driver's seat belt, are equipped with a
child seat lock, to which a child restraint sys-
tem can be secured safely. You can find fur-
ther information under "Child seat lock"
(Y page

61). Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop.
X Press the release button in the belt buckle,
hold the belt tongue firmly and guide the
belt back.
Belt warning for drivers and co-drivers The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts cor-
rectly. It may light up continuously or flash. In
addition, there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 7 seat belt
warning lamp lights up for six seconds each
time the engine is started. If the front doors
are closed and the driver's or front-passenger
seat belt has not been fastened, the 7 seat
belt warning lamp lights up again after the six
seconds. As soon as the driver's and front-
passenger seat belts are fastened or a front
door is opened again, the 7 seat belt warn-
ing lamp goes out.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the driver's
seat belt is fastened.
If the vehicle's speed exceeds

15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warn-
ing tone sounds. A warning tone also sounds
with increasing intensity for 60 seconds or
until the driver or front passenger have fas-
tened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again. 50

Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
Conditions To be classified correctly, 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, OCS may produce a false classifi-
cation, 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
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.
a cushion. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The back-
rest of the forward-facing child restraint sys-
tem 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 a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation and operat-
ing instructions. Occupant Classification System (OCS)

PASSENGER AIR BAG OFF indicator lamp
:
shows you whether the front-passenger front
air bag is deactivated.
X Turn the SmartKey to position 1 or 2 in
the ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then displays the status of the front-passenger
front air bag. If the status of the front-
passenger front air bag changes while the
vehicle is in motion, an air bag display mes-
sage may appear on the instrument cluster: R in vehicles without steering wheel buttons
(Y page
197)
R in vehicles with steering wheel buttons
(Y page 211)
When the front-passenger seat is occupied,
always pay attention to the PASSENGER AIR
BAG OFF indicator lamp. Be aware of the sta-
tus of the front-passenger front air bag both
before and during the journey.
If the PASSENGER AIR BAG OFF indicator
lamp:
R lights up, the front-passenger front air bag
is deactivated. It will then not be deployed
in the event of an accident.
R is not it , the front-passenger front air bag is
enabled. If, in the event of an accident, all
deployment criteria are met, the front-
passenger front air bag is deployed. G

ation is not high. Conversely, air bags may be
deployed even though the vehicle suffers only
minor deformation. This is the case if, for
example, very rigid vehicle parts such as longi-
tudinal body members are hit, and sufficient
deceleration occurs as a result.
If the restraint system control unit detects a
side impact or if the vehicle rolls over, the
applicable components of the restraint system
are deployed independently of each other
depending on the apparent type of accident.
R Side impact air bag and pelvis air bag on the
side on which an impact occurs, independ-
ent from the Emergency Tensioning Device
and seat belt usage
The side impact air bag on the front
passenger side deploys under the following
conditions:
- the OCS system detects that the front
passenger seat is occupied or
- the seat belt buckle tongue is engaged in
the belt buckle of the front passenger
seat
R Window curtain air bag on the side of
impact, independently of the use of the seat
belt and independently of whether the front-
passenger seat is occupied
R Emergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
R Window curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the
seat belt
i Not all air bags are deployed in an acci-
dent. The various air bags work independ-
ently of each other.
How the air bag works is determined by the
severity of the accident detected, especially
the vehicle deceleration or acceleration and
the apparent type of accident:
R Head-on collision
R Side impact
R Rollover Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
R the hazard warning lamps are switched on
R the emergency lighting in the interior is acti-
vated
R the vehicle doors are unlocked
R the front side windows are lowered
R air-recirculation mode is activated
R climate control is switched off
R the engine is switched off and the fuel sup-
ply is cut off Children in the vehicle
Important safety notes
Accident statistics show that children secured
on the rear seats are safer than children
secured on the front seats. For this reason,
Mercedes-Benz strongly advises that you fit
the child restraint system to a rear seat. The
child is generally better protected there.
If a child younger than twelve years old and
under 5 ft
(1.50 m) in height is traveling in the
vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R always observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's instruc-
tions.
R always observe the instructions and safety
notes on the "Occupant Classification Sys-
tem (OCS)" ( Y page 54). G
WARNING
If children are left unsupervised in the vehi-
cle, they could, in particular:
R open doors, thereby endangering other
persons or road users.
R get out and be struck by oncoming traffic.
R operate vehicle equipment and become
trapped, for example.60
Children in the vehicle
Safety

In addition, children could set the vehicle in
motion, for example, if they:
R release the parking brake.
R change the transmission position.
R start the vehicle.
There is a risk of accident and injury.
Never leave children unsupervised in the
vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Keep the SmartKey out of the reach of chil-
dren. G
WARNING
If persons, particularly children are subjec-
ted to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle.
Make sure that all vehicle occupants have fas-
tened their seat belts properly and are seated
correctly. This is particularly important for chil-
dren.
Observe the safety notes on seat belts
(Y page
48) and the notes on the correct use
of the seat belt (Y page 49).
A booster seat may be necessary to achieve
proper seat belt positioning for children over
40 lbs (18 kg) until they reach a height where
a three-point seat belt fits properly without a
booster seat. Special seatbelt retractor
G
WARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat
belt cannot be immediately refastened.
There is an increased risk of injury, possibly
even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reacti-
vate the special seat belt retractor and
secure the child restraint system properly.
All seat belts in the vehicle, except the driver's
seat belt, are equipped with a special seat belt
retractor. When activated, the special seat belt
retractor ensures that the seat belt cannot
slacken once the child seat is secured.
Installing a child restraint system:
X Make sure you observe the child restraint
system manufacturer's installation instruc-
tions.
X Pull the seat belt smoothly from the belt
outlet.
X Engage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
X Pull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat
belt retractor is enabled.
X Push the child restraint system down so that
the seat belt is tight and does not loosen.
Removing the child restraint system and deac-
tivating the special seat belt retractor:
X Make sure you observe the child restraint
system manufacturer's installation instruc-
tions.
X Press the release button of the seat belt
buckle and guide the seat belt tongue back
towards the belt sash guide.
The special seat belt retractor is deactiva-
ted. Children in the vehicle
