Vehicle equipment
i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual. Occupant safety
Introduction
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R Seat belts
R Child restraints
R Lower Anchors and Tethers for CHildren
(LATCH) also known as ISOFIX
Additional
protection potential is provided by:
R Supplemental Restraint System (SRS) with
- Air bags
- Air bag control unit (with crash sensors)
- Emergency Tensioning Device (ETD) for
seat belts
- Seat belt force limiter
R NECK-PRO active front head restraints
R Preventive occupant safety (PRE-SAFE
®
)
R Air bag system components with
-Front passenger front air bag off
indicator lamp
- Front passenger seat with Occupant
Classification System (OCS)
Although the systems are independent, their
protective

functions work in conjunction with
each other. 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 52) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.
The SRS indicator lamp + in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than

a few seconds after the engine has been
started.
The SRS components are in operational
readiness when the SRS indicator lamp
+ is not lit while the engine is running. 36

followed. These instructions are available
from any authorized Mercedes-Benz
Center.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you inform the subsequent
owner that the vehicle is equipped with SRS.
Also refer them to the applicable section in
the Operator’s Manual.
Front air bags G
Observe Safety notes, see page 37. Driver’s front air bag
: and front passenger
front air bag ; are designed to provide
increased protection for the driver and front
passenger against the risk of injuries to the
head and thorax.
Driver and front passenger front air bag and
driver’s side knee bag 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 respective seat
belt is in use
R independently of the side impact air bags
and/or the window curtain air bags The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bags to have different rates of inflation.
The rate of inflation is based on the vehicle
deceleration rate as assessed by the air bag
control unit.
The front passenger front air bag deployment
is additionally influenced by the passenger’s
weight category as identified by the Occupant
Classification System (OCS) (
Y page 41).
The lighter the front passenger-side
occupant, the higher the vehicle deceleration
rate required for second stage inflation of the
front passenger front air bag.
The air bags will not deploy in impacts which
do not exceed the system’s preset
deployment thresholds. You will then be
protected by the fastened seat belts.
The front air bags will not deploy in the event
of a rollover unless the vehicle’s rate of
longitudinal deceleration or acceleration
exceeds the preset deployment threshold for
the front air bags.
The front passenger front air bag will only be
deployed if
R the system, based on OCS weight sensor
readings, detects that the front passenger
seat is occupied
R the 04 indicator lamp in the
center console is not lit (Y page 41)
R the impact exceeds a preset deployment
threshold
Knee bag
Knee bag = is designed to provide increased
protection for the driver against the risk of
injuries to the knees, thighs and lower legs.
Knee bag = is located on the driver side
lower instrument panel. It is designed to
operate together with the driver front air bag
in certain frontal impacts if the system
determines that air bag deployment can offer
additional protection to that provided by the
seat belt. Knee bag = operates best in 40

weight category determined by weight sensor
readings from the front passenger seat.
The system does not deactivate
R
the front passenger side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices (ETDs)
To
be classified correctly, the front passenger
must sit
R with the seat belt properly fastened
R in a position that is as upright as possible
with the back against the seat backrest
R with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
Furthermore, the occupant weight may
appear to increase or decrease due to the
following:
R objects hanging on the seat
R objects lodged underneath the seat
R objects stuffed between the seat and
middle console
R objects stuffed between the seat and door
R other passengers pushing on the seat
R objects applying pressure to the back of
the seat
Always make sure the seat has clearance
in all directions at all times.
If your seat, including the trim cover and
cushion, needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the 04
indicator lamp as an indication of whether or
not the front passenger is properly
positioned. G
Warning!
If the 04 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 04 indicator lamp goes out,
or

check whether objects are caught under or
around the seat.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
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
empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 04 indicator 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,
the 04 indicator 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 occupant is classified as
being heavier than the weight of a typical
12-month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
04 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the seat, remain
illuminated or go out. With the
04 indicator lamp illuminated,
the front passenger front air bag is
deactivated. With the 04 42
