Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident. The restraint system can also reduce the forces
to which vehicle occupants are subjected during an accident.
The restraint system includes the:
R seat belt system
R airbags
R child restraint system
R child seat securing system The components of the restraint system work in
conjunction with each other. They can only offerprotection if all vehicle occupants always:
R have the seat belt correctly fastened
(Y page 44)
R have the seat and head restraint adjusted
properly (Y page 106)
As the driver, you must also make sure that the
steering wheel is also adjusted properly.
Observe the information on the correct driver's
seat position (Y page 106).
In addition, you must make sure that the airbags can inflate properly if they are deployed
(Y page 46).
An airbag supplements a correctly worn seat
belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. The air-
bags are not deployed, for example, in the event
of an accident in which sufficient protection is
offered by the seat belt. In addition, only those
airbags, which in the applicable accident situa-
tions offer additional protection, are deployed in the event of an accident. However, the seat beltand airbag generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on how the restraint system oper-
ates can be found under "Deployment of belt
tensioners and airbags" (Y page 53).
See "Children in the vehicle" for information on
children travelling with you in the vehicle as well
as on child restraint systems (Y page 56). Important safety notes

WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to adjust the vehicle to accom- modate a person with disabilities, contact a
qualified specialist workshop. Occupant safety

Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz. 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 on 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 may not deploy as
intended during an accident. This may affect
the seat belt tensioner or airbag, for example. This poses an increased risk of injury or even
fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the event of an accident.
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 PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator
lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must be
either 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. Make sure
that you read the notes on the "Automatic
front-passenger front airbag deactivation sys-
tem" (Y page 49) and on "Children in the
vehicle" (Y page 56).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of
the child, the front-passenger front airbag is
either disabled or enabled. Therefore, make
sure that you read the notes on the "Auto-
matic front-passenger front airbag deactiva- 42

arm or behind your back. If possible, adjust
the seat belt to the appropriate height.
R the lap belt is taut and passes across the lap
as low down as possible
The lap belt must always be routed across
your hip joints and never across your abdo-
men. This applies particularly to pregnant
women. If necessary, press the lap belt down
into your hip joints and pull tight with the
shoulder section of the belt.
R the seat belt is not routed across sharp, poin-
ted or fragile objects
If you have such items located on or in your
clothing, e.g. pens, keys or spectacles, store
these in a suitable place.
R only one person is using a seat belt
Infants and children must never travel sitting
on the lap of a vehicle occupant. In the event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R objects are never secured with a seat belt if
the seat belt is also being used by one of the
vehicle's occupants
Also ensure that no objects are placed
between a person and the seat. e.g. a cush-
ion.
Seat belts are intended only to secure and
restrain vehicle occupants. Always observe the
"Loading guidelines" for securing objects, lug-
gage or loads (Y page 288).
Fastening and adjusting the seat belts Observe the safety notes on the seat belt
(Y
page 43) and the information on the correct
use of the seat belt (Y page 44). Basic illustration X
Adjust the seat (Y page 106).
The seat backrest must be in an almost
upright position.
X Pull the seat belt smoothly from the belt out-
let.
X Engage seat belt tongue ;in belt buckle :.
The seat belt on the driver's seat and the
front-passenger seat may be tightened auto-
matically; see "Belt adjustment"
(Y page 45).
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 seat belt must
always be routed across the centre of the shoul- der. Adjust the belt outlet if necessary.
X To raise: slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions.
X To lower: hold belt outlet release =and slide
the belt outlet downwards.
X Let go of belt outlet release =in the desired
position and make sure that the belt outlet
engages.
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. Damaged seat belts
can no longer fulfil their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press release button in belt buckle, hold belt
tongue firmly and guide the seat belt back.
Belt adjustment Seat-belt adjustment is an integral part of the
PRE-SAFE
®
convenience function. With this
function, the driver's and co-driver's seat belts
are adjusted to the upper body of the vehicle
occupant.
The belt strap is tightened slightly when:
R the belt tongue is engaged in the buckle and
R the ignition is switched on
The seat belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not Occupant safety

therefore cannot protect as intended. There is
an increased risk of injury, possibly even fatal.
Have pyrotechnic belt tensioners which have
been triggered replaced at a qualified special-
ist workshop immediately.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident. Take this into account, par-
ticularly if a seat belt tensioner was triggered or
an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If the belt tensioners are triggered or an airbag is
deployed, you will hear a bang, and a small
amount of powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-
ing. In general, the powder released is not haz-
ardous to health but may cause short-term
breathing difficulties to persons suffering from
asthma or other pulmonary conditions. Provided it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre- vent breathing difficulties.
Operation During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the seat
belt tensioners in the event of a head-on or rear
collision.
A seat belt tensioner can be triggered only if:
R the ignition is switched on
R the components of the restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
(Y page 42)
R the seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The seat belt tensioners in the rear compart-
ment are triggered independently of the lock
status of the seat belts. If the restraint system control unit detects a
high-severity accident, in certain head-on colli-
sions, additional components of the restraint
system are deployed independently of each
other:
R front airbags and driver's kneebag
R windowbag, if the system determines that
deployment can offer additional protection to
that provided by the seat belt
On vehicles with the automatic front-passenger
front airbag deactivation system: depending on
the person in the front-passenger seat, the
front-passenger front airbag is either disabled or
enabled. The front-passenger front airbag can
be deployed in an accident only if the
PASSENGER AIR BAG OFF indicator lamp is off. Observe the information on the PASSENGER AIR
BAG indicator lamps (Y page 42).
Your vehicle has two-stage front airbags. In the
first deployment stage, the front airbag is filled
with propellant gas. The front airbag is fully
deployed if the second deployment stage is acti-
vated within a few milliseconds.
The activation threshold for the seat belt ten-
sioners and airbags is determined based on the
evaluation of the vehicle's rate of deceleration
or acceleration at various points in the vehicle.
This process is pre-emptive in nature. The trig-
gering/deployment process should take place
in good time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
R the distribution of forces during the collision
R the collision angle
R the deformation characteristics of the vehicle
R the characteristics of the object with which
the vehicle has collided
Factors that can be seen and measured only
after a collision has occurred do not play a deci-
sive role in the deployment of an airbag. Nor do
they provide an indication of airbag deployment.
The vehicle may be deformed significantly with- out an airbag being deployed. This is the case if only parts that are relatively easily deformed are
affected and the rate of deceleration is not high. Conversely, an airbag may be deployed even
though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result. 54

that you do not interfere with the correct rout-
ing of Top Tether belt ?.Child restraint system on the front-
passenger seat
General notes Accident statistics show that children secured
on the rear seats are safer than children secured on the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat.
Vehicles with the automatic front-
passenger front airbag deactivation system:
if it is absolutely necessary to fit a child restraint
system to the front-passenger seat, always
observe the information on the "Automatic
front-passenger front airbag deactivation sys-
tem" (Y page 49).
You can thus avoid the risks that could arise as a result of:
R a child restraint system that is not detected
by the automatic front-passenger front airbag
deactivation system
R unintentional disabling of the front-passenger
front airbag
R unsuitable positioning of the child restraint
system, e.g. too close to the dashboard Please observe the warning notice on the
front-passenger sun visor; see illustration. G
WARNING
If you secure a child in a rearward-facing 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.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it; DEATH or SERIOUS INJURY to the
child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
goes out, the front-passenger front airbag is
enabled (Y page 42).
Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is not
equipped with the automatic front-passenger
front airbag deactivation system, this is indica-
ted by a special sticker. The sticker is affixed to
the side of the dashboard on the front-
passenger side. The sticker is visible when you
open the front-passenger door.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps light
up briefly. However, they have no function and
do not indicate that there is an automatic front- passenger front airbag deactivation system.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 61).
Observe the following information under "Rear-
ward-facing child restraint system"
(Y page 61) and "Forward-facing child
restraint system" (Y page 61) as well as infor-
mation on the suitable positioning of the child
restraint system (Y page 61).60
