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 Roll bar
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.
GWarning!
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 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.
GWarning!
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

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.GWarning!
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 driver’s
side knee bag) 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.
Safety guidelines for the seat belt,
Emergency Tensioning Device (ETD)
and air bag GWarning!
R Damaged 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

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.
Occupant Classification System
The Occupant Classification System (OCS)
activates or deactivates the passenger front
air 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 45 indicator lamp as
an indication of whether or not the passenger
is properly positioned.
GWarning!
If the 45 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 45 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
45 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 45
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 45 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 45 indicator lamp
illuminated, the passenger front air bag is
deactivated. With the 45 indicator
lamp out, the passenger front air bag is
activated.
When the OCS senses that the passenger seat
occupant is classified as an adult or someone
larger than a small individual, the 45
indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then goes out, indicating that the

If the 45 indicator lamp is illuminated,
the passenger front air bag is deactivated and
will not be deployed.
If the 45 indicator lamp is not
illuminated, the passenger front air bag is

For more information on air bag display
messages in the multifunction display, see
( Y page 229).GWarning!
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
important information:
R Your vehicle is equipped with air bag
technology designed to deactivate the
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the passenger seat.
R A child in a rear-facing child restraint on the
passenger seat will be seriously injured or
even killed if the passenger front air bag
inflates in a collision which could occur
under some circumstances, even with the
air bag technology installed in your vehicle.
R If you install a rear-facing child restraint on
the passenger seat, make sure the
45 indicator lamp is illuminated,
indicating that the passenger front air bag
is deactivated. Should the 45
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
45 indicator lamp while driving to
make sure the 45 indicator lamp is
illuminated. If the 45 indicator lamp
goes out or remains out, do not transport a
child on the passenger seat until the
system has been repaired.
A child in a rear-facing child restraint on the
passenger seat will be seriously injured or
even killed if the passenger front air bag
inflates.
R If you place a child in a forward-facing child
restraint on the passenger seat, move the
seat as far back as possible, use the proper
child restraint recommended for the age,
size and weight of the child, and secure
child restraint with the vehicle’s seat belt
according to the child seat manufacturer’s
instructions. For children larger than the
typical 12-month-old child, the passenger
front air bag may or may not be activated.
Deployment of the driver front air bag does
not mean that the passenger front air bag also
should have deployed.
The OCS may have determined
R that the seat was empty or occupied by the
weight up to or less than that of a typical
