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
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 Air bag system components with
-Passenger 
front air bag off indicator lamp
- 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 45) 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. G
Warning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
+
R does not come on at all
R fails to go out after approximately
4 seconds after the engine was started
R comes on after the engine was started or
while driving
For 
your safety, we strongly recommend that
you contact an authorized Mercedes-Benz
Center immediately to have the system
checked. Otherwise the SRS may not be
activated when needed in an accident, which 32

thorax air bag be deployed. 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.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual. G
Warning!
There is a possibility of a head-thorax air bag-
related injury if occupants, especially
children, 
are not properly seated or restrained
when next to a head-thorax air bag which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should 
 never place their bodies or
lean their heads in the area of the
door where the head-thorax air
bag inflates. This could result in
serious injuries or death should
the head-thorax air bag be
deployed.
(2) Always sit as upright as possible, wear 
the seat belt properly, and for
children 12 years old and under,
use an appropriately sized infant
restraint, toddler restraint, or
booster seat recommended for the
size and weight of the child.
(3) Always wear seat belts properly.
If you believe that, even with the use of these
guidelines, it would be safer for your
passenger seat occupants to have the
passenger side head-thorax air bag
deactivated, 
then deactivation can be carried
out upon your written request at an authorized Mercedes-Benz Center at an
additional cost.
Please 
contact an authorized Mercedes-Benz
Center or call the Customer Assistance
Center (in the USA) at 1-800-FOR-MERCedes
(1-800-367-6372), or Customer Service (in
Canada) at 1-800-387-0100 for details.
Air bags are designed to deploy only in certain
frontal impacts (front air bags and knee bags)
and in side impacts (head-thorax air bags) if
the system determines the need for air bag
deployment. Only in the event of such a
situation will they provide their supplemental
protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible
for the air bags to provide their supplemental
protection.
In case of other types of impacts and impacts
below air bag deployment thresholds, air
bags will not deploy. The driver and passenger
will then be protected to the extent possible
by a properly fastened seat belt. A properly
fastened seat belt is also needed to provide
the best possible protection in a rollover.
Air bags are not a substitute for seat belts.
Always wear your seat belt, regardless of
whether or not your vehicle is equipped with
air bags.
It is important to your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags will continue to provide supplemental
crash protection for occupants.

The passenger head-thorax air bag  : will
only deploy if the OCS senses that the
passenger seat is occupied and the impact
exceeds a preset deployment threshold.
Head-thorax air bags  : are not deployed in
side impacts which do not exceed the
system’s deployment threshold. G
Warning!
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the head-thorax air bags. Contact an
authorized Mercedes-Benz Center for
availability. Occupant Classification System
The Occupant Classification System (OCS)
activates or deactivates the passenger front
air bag and passenger-side knee bag
automatically. 
The respective status is based
on the classified occupant weight category
determined by weight sensor readings from
the passenger seat.
The system does not deactivate the
passenger head-thorax air bag and the
Emergency Tensioning Devices (ETDs).
To be classified correctly, the 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.
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 passenger should
always use the 
04 indicator
lamp as an indication of whether or not the
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 passenger
seat, have the passenger reposition himself
or herself in the seat until the
04 indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow passenger front air bag
deployment when the OCS has classified the
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
passenger seat is classified as being empty.
When 
the OCS senses that the 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 passenger
front air bag is deactivated.
When the OCS senses that the passenger seat
is classified as being empty, the
04 indicator lamp will illuminate
when the engine is started and remain
illuminated, indicating that the passenger
front air bag is deactivated.
When the OCS senses that the 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 Occupant safety

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.
Children can be killed or seriously injured by
an inflating air bag. Note the following
