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 comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 40)
R adjust their seat and head restraint properly
(Y page 99).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (Y page 99).
You also have to make sure that an airbag can
inflate properly if deployed (Y page 42).
An airbag supplements a correctly fastened seat belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection of the seat belt is sufficient in an accident, the airbags are not deployed. In
the event of an accident, only the airbags that
increase protection in the relevant accident sit- uation are deployed. However, seat belts and
airbags generally do not protect against objects penetrating the vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tension-
ers and airbags" (Y page 45).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (Y page 49). Important safety notes
G
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 modify an airbag system to
accommodate a person with disabilities, con-
tact a Mercedes-Benz Service Centre. Occupant safety
37Safety Z

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 in 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 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. There is an increased risk of serious or even
fatal injuries.
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 automatic child seat recognition on
the front-passenger seat.
A permanently lit PASSENGER AIR BAG OFF
indicator lamp informs you that the front-
passenger front airbag is disabled.
Depending on the person in the front-passenger seat, the front-passenger front airbag 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 child restraint system:
whether the front-passenger front airbag is
enabled or disabled depends on the installed
child restraint system, and the age and size of the child. Therefore, it is imperative to
observe the notes on "Children in the vehicle"
(Y page 49). There you will also find infor-
mation on rearward or forward-facing child
restraint systems on the front-passenger
seat.
R All other persons: the PASSENGER AIR BAG
OFF indicator lamp must be off. Be sure to
observe the notes on "Seat belts"
(Y page 38) and "Airbags" (Y page 42).
There you can also find information on the
correct seat position.
Observe the information on automatic child seat recognition in the front-passenger seat
(Y page 51). Seat belts
Introduction A correctly worn seat belt is the most effective
means of restraining the movement of vehicle
occupants in the event of a collision or if the
vehicle overturns. This reduces the risk of vehi- cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag 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 38

front-passenger seat may be tightened auto-
matically, see "Belt adjustment"
(Y page 41).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
In order to attach the child restraint system
securely in the vehicle, the seat belts in the rear
are equipped with a child seat lock. You can find
further information under "Child seat lock"
(Y page 50).
Automatic comfort-fit feature The front seat belts have an automatic comfort-
fit feature. The automatic comfort-fit feature
reduces the retraction force of the seat belts.
The seat belts are thus routed more comfortably for the driver and front passenger.
Releasing the 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.
Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE
®
convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants.
The belt strap is tightened slightly when:
R with a retracted seat-belt extender, the seat
belt tongue is engaged in the belt 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
41Safety Z

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 only be triggered 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 38)
R the belt 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 collisions,
additional components of the restraint system
are deployed independently of each other:
R front airbags and driver's kneebag
R headbag, if the system determines that
deployment can offer additional protection to
that provided by the seat belt
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 only be deployed in an accident if the
PASSENGER AIR BAG OFF indicator lamp is off. Observe the information on the PASSENGER AIR
BAG OFF indicator lamp (Y page 38).
Your vehicle has two-stage front airbags. In the
first deployment stage, the front airbag is filled
with propellant gas to reduce the risk of injuries. The front airbag is fully deployed if the second
deployment stage is activated within a few mil-
liseconds.
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 which can only be seen and measured
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 which 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
deformation. This is the case if, for example,
very rigid vehicle parts such as longitudinal 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 overturns, the applicablecomponents of the restraint system are activa-
ted independently of each other depending on
the apparent type of accident.
R Sidebags and pelvisbag on the side on which
an impact occurs, independent from the seat
belt tensioner and seat belt usage
Vehicles with the automatic child seat recog-
nition on the front-passenger seat: the side-
bag and pelvisbag on the front-passenger side (front) deploy under the following conditions:
- an occupant is detected on the front-
passenger seat or
- the belt tongue is engaged in the belt
buckle of the front-passenger seat
R Headbag on the side on which an impact
occurs, independent of seat belt usage and
regardless of whether the front-passenger
seat is occupied
R Seat belt tensioners, if the system determines
that deployment can offer additional protec-
tion for the vehicle occupants in this situation
R Headbags on the driver's and front-passenger
side in certain situations if the vehicle over-
turns and if the system determines that
deployment can offer additional protection to that provided by the seat belt 46

airbag is disabled.
X Turn the key to position 1or 2in the ignition
lock or, on vehicles with KEYLESS-GO, press
the Start/Stop button once or twice.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp:
R lights up , the front-passenger front airbag is
disabled. It will then not be deployed in the
event of an accident.
R is not lit , the sensor system did not detect a
child restraint system with transponder for
automatic child seat recognition. If, in the
case of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed. G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of the front-passenger front airbag both before and
during the journey. Child restraint system on the front-
passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in the front seats. For this reason, Mercedes- Benz strongly advises that you fit a child
restraint system on a rear seat.
Vehicles with automatic child seat recognition
on the co-driver's seat: if it is absolutely neces-
sary to fit a child restraint system to the co-driv- er's seat, always observe the notes on "Auto-
matic child seat recognition on the co-driver's
seat" (Y page 53).
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 child seat recognition's sen-
sor system
R the unintentional disabling of the co-driver's
front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board. Please observe the warning notice on the co-
driver's sun visor, see the illustration. G
WARNING
If you secure a child in a 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. Children in the vehicle
53Safety Z

Vehicles without automatic child seat
recognition on the co-driver's seat If the co-driver's seat of your vehicle is not
equipped with automatic child seat recognition,
this is indicated by a special sticker. The sticker
is affixed to the side of the dashboard on the co-
driver's side. The sticker is visible when you
open the co-driver's door.
The PASSENGER AIR BAG OFF indicator lamp
lights up briefly when the key is turned to posi-
tion 2in the ignition lock. It has no function,
however, and does not indicate that the co-driv- er's seat is equipped with automatic child seat
recognition.
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. They have no function, however, and do not indicate that the co-driver's seat is equip-
ped with automatic child seat recognition.
Always fit the rearward-facing restraint system
to a suitable rear seat in this case (Y page 55).
Observe the following information under "Rear-
ward-facing child restraint system" and
"Forward-facing child restraint system" and on
suitable positioning of the child restraint system
(Y page 55). Rearward-facing child restraint system Warning symbol for a rearward-facing child
restraint system
If it is absolutely necessary to fit a rearward-
facing child restraint system to the co-driver's
seat, you must always make sure that the co-
driver's front airbag is deactivated. The co-driv-
er's front airbag is only disabled if the
PASSENGER AIRBAG OFF indicator lamp is lit
continuously (Y page 38).
Always observe the information about suitable
positioning of the child restraint system
(Y page 55) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions.
Forward-facing child restraint system If you secure a child in a forward-facing child
restraint system on the co-driver's seat, you
must always move the co-driver's seat as far
back as possible. The base of the child restraint system must lie fully on the co-driver's seat
cushion. The backrest of the child restraint sys-
tem must lie as flat against the co-driver's seat
backrest as possible. The child restraint system may 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 accord-
ingly. Always make sure that the shoulder belt
strap is correctly routed from the seat-belt
extender on the co-driver's seat to the shoulder belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
from the retracted seat-belt extender for the co-driver's seat.
Always observe the information about suitable
positioning of the child restraint system
(Y page 55) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions. 54
