Air bags
GWarning!
Air bags are designed to reduce the potential
of injury and fatality in certain
R frontal impacts (front air bags and knee
bags)
R side impacts (side impact air bags and head
air bags)
However, no system available today can
completely eliminate injuries and fatalities.
Deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither harmful
to your health, nor does it indicate a fire in the
vehicle. The dust might cause some
temporary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get fresh
air by opening a window or door.
GWarning!
To reduce the risk of injury when the front air
bags inflate, it is very important for the driver
and passenger to always be in a properly
seated position and to wear their seat belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body.
Since the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag as it
inflates with great force instantaneously:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R Move the driver’s seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver’s chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm) or more.
You should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
R Do not lean your head or chest close to the
steering wheel or dashboard.
R Keep hands on the outside of the steering
wheel rim. Placing hands and arms inside
the rim can increase the risk and potential
severity of hand/arm injury when the driver
front air bag inflates.
R Adjust the passenger seat as far as possible
rearward from the dashboard when the
seat is occupied.
R Occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the head air
bag inflates. This could result in serious
injuries or death should the head 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 safetyOccupant safety45Safety and securityBA 197 USA, CA Edition A 2011; 1; 27, en-UShereepeVersion: 3.0.3.52010-03-24T15:31:10+01:00 - Seite 45Z
information. Be sure to give the buyer this
Operator’s Manual.GWarning!
There is a possibility of a head air bag-related
injury if occupants, especially children, are
not properly seated or restrained when next
to a head 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 air bag
inflates. This could result in
serious injuries or death should
the head 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 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 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
installed or supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check with your local
government’s disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm .
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced.

weight category as identified by the Occupant
Classification System (OCS) (Y page 49).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
for second stage inflation of the 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 passenger air bag will only be deployed if
Rthe system, based on OCS weight sensor
readings, detects that the passenger seat
is occupied
Rthe 4 5 indicator lamp in the center
console is not lit
Rthe impact exceeds a preset deployment
threshold
Knee bags
The knee bags are designed to provide
increased protection for the driver and
passenger against the risk of injuries to the
knees, thighs and lower legs.
Driver side knee bag : is located on the
driver side lower instrument panel. Passenger
side knee bag ; is located on the passenger
side below the glove box. They are designed
to operate together with the front air bags in
certain frontal impacts if the system
determines that air bag deployment can offer
additional protection to that provided by the
seat belt. The knee bags operate best in
conjunction with properly positioned and
fastened seat belts.
Side impact air bags
GObserve Safety notes, see page 45.GWarning!
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 side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability.
GWarning!
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the
addition of door speakers.
Improper repair work on the doors or the
modification or addition of components to the
doors create a risk of rendering the side
impact air bags inoperative or causing
unintended air bag deployment. Work on the
doors must therefore only be performed by
qualified technicians. Contact an authorized
Mercedes-Benz Center.

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
Rthe passenger head air bag
Rthe passenger side impact air bag
Rthe Emergency Tensioning Devices (ETDs)
To be classified correctly, the passenger must
sit
Rwith the seat belt properly fastened
Rin a position that is as upright as possible
with the back against the seat backrest
Rwith 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 4 5 indicator lamp as
an indication of whether or not the passenger
is properly positioned.GWarning!
If the 4 5 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 4 5 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 4
5 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 4 5
indicator lamp will illuminate when the engine

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 4 5 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 4 5 indicator lamp

Children can be killed or seriously injured by
an inflating air bag. Note the following
important information:
RYour 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.
RA 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.
RIf you install a rear-facing child restraint on
the passenger seat, make sure the 4
5 indicator lamp is illuminated,
indicating that the passenger front air bag
is deactivated. Should the 4 5
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the 4
5 indicator lamp while driving to make
sure the 4 5 indicator lamp is
illuminated. If the 4 5 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.
RIf 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
Rthat the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both of which are instances
where the system suppresses deployment
of the passenger front air bag even though
the impact met the criteria and was of
sufficient severity to deploy the driver front
air bag
Rthat the seat was occupied by a small
individual (such as a young teenager or a
small adult) or a child who weighs more
than the weight of a typical 12-month-old
child in a standard child restraint – both of
