You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes.
This could lead to malfunctions in safety-
relevant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and
accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strictqualitycontrol. Every part hasbeen
specifically developed,manufactured or

possible.Bear in mind that your vehicle may
not feature all functionsdescribed here. This
also applies to safety-relevant systems and
functions. The equipment in your vehicle may
therefore differ from that shown in the
descriptions and illustrations.
The original purchase agreement lists all

SRS (Supplemental Restraint System)
Introduction
RS consistsof:
RTheRS warning lamp
RAir bags
RThe air bag control unit with crash sensors
REmergency Tensioning Device for the front
seat belts and the outer seat belts in the
rear
RSeat belt force limiters for the front seat
belts and the outer seat belts in the rear
RS 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 warning lamp
GWARNING
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an accident withahigh rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
ataqualified specialist workshop.
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.
TheSRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later thanafew seconds
after the engine is started.
The SRS components are in operational
readiness when theSRS indicator lamp
goes out while the engine is running.
There isamalfunction if:
RtheSRS warning lamp does not light
up when the ignition is switched on
Rthe engine is running and theSRS
warning lamp does not go out afterafew
seconds
Rthe engine is running and theSRS
warning lamp lights up again.
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
GWARNING
RDamaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-BenzCenter.
RAir bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
RAir bags and ETDs are designed to function
onaone-time-only basis. An air bag or ETD
that has deployed must be replaced. PRE-
SAFE®has electrically operated reversible
belt tensionersinaddition to the
pyrotechnic ETDs.
RDo not pass seat belts over sharp edges.
They could tear.
RDo not make any modification that could
change the effectiveness of the seat belts.
RDo not bleach or dye seat belts as this may
severely weaken them. Inacrash they may
not be able to provide adequate protection.

totalavailablepropellant gas, thereby
reducing the risk of injury.Ifthe airbag
control unitrecognizeswithinafew
milliseconds thatthe vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amount of propellant gas available.
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) (Ypage 47).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second-stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations wherealow impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only
deploy if:
Rthe system, based on the OCS weight
sensor readings, detectsthat the front-
passenger seat is occupied
Rthe PASSENGER AIR BAG OFF indicator
lamp on the center console is not lit
(Ypage 47)
Rthe air bag control unit predictsahigh
impact severity
Knee bags
Driver's knee bagdeploysunderneath the
steering column and front-passenger knee
bagunderneath the glove box. They
deploy together with the front air bags. They
are designed to operate together with the
front air bags in frontal impacts if certain
thresholds are exceeded. The knee bags
operate at best in conjunction with correctly
positioned and fastened seat belts.
Knee bags provide increased protection for
the driver and front passenger against the risk
of:
Rknee injuries
Rthigh injuries
Rlower leg injuries
Side impact air bags
GWARNING
Using unsuitable seat covers could restrict or
even prevent deployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protect vehicle occupants as
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not
performed correctly to the doors or door
paneling, as well as damaged doors, can lead
to the function of the sensors being impaired.
The air bags might therefore not function
properly any more. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door
paneling carried out ataqualified specialist
workshop.

When the OCS senses that the front-
passenger seat occupant is classified as
being up to or less than the weight ofatypical
12-month-old child inastandard child
restraint,theindicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front-
passenger front air bag is deactivated.
When the OCS senses that the front-
passenger seat is classified as being empty,
theindicator lamp will illuminate
when the engine is started and remain

When the OCS senses that the front-

being heavier than the weight ofatypical 12-
month-old child seated inastandardchild

asayoung teenager orasmall adult), the

approximately6seconds when the engine is
started and then,depending on occupant
weight sensor readings from the front-

With theindicator lamp
illuminated, the front-passenger frontair bag
is deactivated. With theindicator
lamp out, the front-passengerfront air bag is
activated.
When the OCS senses that the front-

individual, theindicator lamp will
illuminate for approximately6seconds when
the engine is started and then go out,
indicating that the front-passenger frontair
bag is activated.
If theindicator lamp is illuminated,
the front-passenger frontair bag and the
front-passenger knee bag are deactivated and
will not be deployed.
If theindicator lamp is not
illuminated, the front-passenger frontair bag
and the front-passengerknee bagare
activatedand will be deployed:
Rin the event of certain frontalimpacts
Rif impact exceedsapreset deployment

Rindependentlyofthe side impact airbag or

influenced by:
Rtherateofrelevantvehicle deceleration as
assessed by the air bag control unit
Rthe frontpassenger's weightcategoryas
identified by OCS
GWARNING
Accordingtoaccidentstatistics, childrenare
saferwhen properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommendthat children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint,toddler restraint,orbooster 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, the seat
belt and Top Tether strap, or lower LATCH-
type (ISOFIX) child seat retaining loops and
Top Tether strap, fully in accordance with the
infant or 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,orbooster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag.
