Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 22).Occupant safety
Introduction
In this section, you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R air bag system components with:
-PASSENGER AIR BAG OFF indicator lamp
- front-passenger seat with Occupant
Classification System (OCS)
The different air bag systems work
independently of each other. The protective
functions of the system work in conjunction
with each other. Not all air bags are deployed
in an accident. G
WARNING
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See "Children in the vehicle"
(Y page 51) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children. SRS (Supplemental Restraint System)
Introduction SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R
6 SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R Emergency Tensioning Devices
R seat belt force limiters
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The
6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. 36
Occupant safetySafety
ProCarManuals.com
Driver's air bag
:deploys in front of the
steering wheel; front-passenger front air
bag ;deploys in front of and above the glove
box. They are deployed:
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other air bags in the
vehicle
If the vehicle rolls over, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in a longitudinal
direction, the front air bags are deployed.
Your vehicle has adaptive, two-stage front air
bags. In the event of a collision, the air bag
control unit evaluates the vehicle
deceleration. When the first deployment
threshold is reached, the front air bag is filled
with enough propellant gas to reduce the risk
of injuries. The front air bag is fully deployed
if a second deployment threshold is exceeded
within a few milliseconds.
The deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 42).
The front air bags are not deployed in
situations where a low impact severity is
predicted. You will then be protected by the
fastened seat belt. The front-passenger front air bag will only be
deployed if:
R
the Occupant Classification System (OCS)
has detected that the front-passenger seat
is occupied
R the 45 indicator lamp on the center
console is not lit
R the air bag control unit predicts a high-
impact severity.
Driver's/front-passenger knee bag The driver and front-passenger knee bags
enhance the level of protection against:
R
knee injuries
R thigh injuries
R lower leg injuries Driver's knee bag
:deploys underneath the
steering column. Front-passenger knee
bag ;deploys underneath the glove box. If,
during a frontal collision, the system
determines that air bag deployment can offer
additional protection to that provided by the
seat belt, the knee bags are deployed along
with the front air bags. The knee bags operate
best in conjunction with correctly positioned
and fastened seat belts.
Side impact air bags G
WARNING
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door 40
Occupant safetySafety
ProCarManuals.com
Example: Coupe
Headbags
:deploy in the side window area.
They are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R if the system determines that the vehicle
occupants are offered additional
protection to that provided by the seat belt
R independently of the use of the seat belt
R independently of the ETDs
R on the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that air bag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
R independently of the front air bags
Head bags :will not deploy in side impacts
which do not exceed the system's preset
deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
If the OCS has classified the front-passenger
seat as unoccupied and the front-passenger
seat belt is not fastened, the head bag on the
passenger side will not deploy. The head bag
on the front-passenger side will deploy if the
front-passenger seat belt is fastened,
regardless of whether the front-passenger
seat is occupied or not. Occupant Classification System
(OCS)
How the Occupant Classification
System works The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor. The
front-passenger front air bag and the front-
passenger knee bag are deactivated
automatically for certain weight categories.
The
45 indicator lamp shows you the
current status. When the 45indicator
lamp is illuminated, the front-passenger front
air bag and the front-passenger knee bag are
deactivated.
The system does not deactivate:
R the front-passenger side impact air bag
R the front-passenger head bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in a position that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
To establish whether the front passenger is
being properly detected, both the driver and
the front passenger should pay attention to
the 45 indicator lamp.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz. 42

WARNING
If the 45 indicator lamp lights up when
the front-passenger seat is occupied by an
adult or a larger person, ask the passenger to
reposition themselves on the seat so that the
45 indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow front-passenger front air
bag and front-passenger knee bag
deployment when the OCS has classified the
front-passenger occupant as weighing as
much as or less than a typical 12-month-old
child in a standard child restraint or if the
front-passenger seat is classified as being
unoccupied.
If OCS has detected that the front passenger
weighs the same as or less than a typical 12-
month-old child in a standard child restraint
system, the 45indicator lamp lights
up when the engine is started and remains lit.
This indicates that the front-passenger front
air bag is deactivated.
If OCS determines that the front-passenger
seat is unoccupied, the 45indicator
lamp lights up once the engine has been
started and remains lit. This shows that the
front-passenger front air bag and front-
passenger knee bag are deactivated.
If OCS determines that the front passenger
weighs more than a typical 12 month old child
in a standard child restraint system and
classifies this as a small person (e.g. a
teenager or small adult), the 45
indicator lamp lights up for approximately 6
seconds when the engine is started.
Depending on occupant weight sensor
readings from the seat, it will then remain
illuminated or go out. If the 45
indicator lamp is illuminated, the front-
passenger front air bag is deactivated. With
the 45 indicator lamp out, the front-
passenger front air bag and front-passenger
knee bag are deactivated.
If OCS has determined that the front
passenger is an adult or medium sized person,
the 45 indicator lamp lights up for approximately 6 seconds when the engine is
started and then goes out. This shows that the
front-passenger front air bag and front-
passenger knee bag are activated.
If the
45 indicator lamp is illuminated,
the front-passenger front air bag and the
front-passenger knee bag are deactivated and
are not deployed.
If the 45 indicator lamp does not light
up, the front-passenger air bag is enabled and
will be deployed:
R in the event of certain frontal impacts
R if the impact exceeds a preset deployment
threshold
R independently of the other air bags
If the front-passenger air bag is deployed, the
rate of inflation is influenced by:
R the rate of vehicle deceleration as assessed
by the air bag control unit
R the front passenger's weight category as
determined by the OCS
For further information, see "Air bag display
messages" (Y page 167). G
WARNING
Children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt fully in
accordance with the child seat
manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child. Occupant safety
