69 Safety and Security
Occupant safety
Warning!G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, emergency tensioning
devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with in-
terconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.
Air bags or emergency tensioning devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the de-
celeration threshold for air bag deployment
is exceeded. Therefore, never modify the re-
straint systems. Do not tamper with elec-
tronic components or their software.
Warning!G
In the event that the 1 indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. 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 deploy when needed in an accident,
which could result in serious or fatal injury,
or it might deploy unexpectedly and unnec-
essarily which could also result in injury.
In addition, improper repair work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.

70 Safety and Security
Occupant safety
Air bags
Warning!G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags, driver-side knee bag)
or side impacts (head-thorax air bags).
However, no system available today can
completely eliminate injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary 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.
Warning!G
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 prop-
erly 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 backrest. Fasten
your seat belt and make sure that it is prop-
erly positioned on your body (
page 50).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:

Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.

Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper
operation of vehicle controls. The dis-
tance from the center of the driver’s
breastbone 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 a
combination of adjustments to the seat
and steering wheel. If you have any
problems, please contact an authorized
Mercedes-Benz Center.

Do not lean your head or chest close to
the steering wheel or dashboard.

Keep hands on the outside of the steer-
ing wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.

Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.

71 Safety and Security
Occupant safety

Occupants, especially children, should
never lean their heads in the area of the
door where the head-thorax air bag in-
flates. This could result in serious inju-
ries or death should the air bag be
deployed. Always sit as upright as possi-
ble, properly use the seat belts and 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 in-
formation. Be sure to give the buyer this
Operator’s Manual.Warning!G
There is a possibility of a head-thorax air bag
related injury if occupants, especially chil-
dren, 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, prop-
erly use the seat belts and for children
12 years old or under, use an appropri-
ately 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 pas-
senger side head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written election to do so at an
authorized Mercedes-Benz Center at an
additional cost.
Please contact your local 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.
iAir bags are designed to activate only in cer-
tain frontal impacts (front air bags, driver-side
knee bag) and side impacts (head-thorax air
bags) which exceed preset thresholds. Only
during these events, 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.

72 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag
In case of other types of impacts and impacts be-
low 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.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
senger that you replace deployed air bags and
repair any malfunctioning air bags to make sure
that the vehicle will continue to provide supple-
mental crash protection for occupants.
Warning!G

Damaged seat belts or seat belts that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Only use
seat belts installed or supplied by an
authorized Mercedes-Benz Center.

Air bags and Emergency Tensioning
Devices (ETDs) contain Perchlorate
material, which may require special han-
dling and regard for the environment.
Check with your local government’s
disposal guidelines. California residents,
see http://www.dtsc.ca.gov/Hazard-
ousWaste/Perchlorate/index.cfm.

Air bags and Emergency Tensioning
Devices (ETDs) are designed to function
on a one-time-only basis. An air bag or
ETD that has deployed must be re-
placed.

Do not pass seat belts over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the seat
belts.

Do not bleach or dye seat belts as this
may severely weaken them. In a crash,
they may not be able to provide ade-
quate protection.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or
removing any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front air bag
cover, door frame trims, or door trim
panels, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages,
purses, umbrellas, etc.).

Air bag system components will be hot
after an air bag has inflated. Do not
touch.

Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

75 Safety and Security
Occupant safety
Both driver and the passenger should
always use the 5/ indicator lamp
as an indication of whether or not the
passenger is properly positioned.
iIf the seat, including the trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only use seat accessories approved by
Mercedes-Benz. Warning!G
If the 5/ indicator lamp illuminates
when an adult or someone larger than a
small individual is in the passenger seat,
have the passenger re-position himself or
herself in the seat until the 5/ indi-
cator lamp goes out.
More information about air bag display
messages (
page 368).
In the event of a collision, the air bag control
unit will not allow passenger front air bag
deployment when the OCS classified the
passenger seat occupant as being up to or
less than the weight of a typical
12-month-old child in a standard child
restraint or if the passenger seat is sensed
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 5/ indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the pas-
senger front air bag is deactivated.
When the OCS senses that the passenger
seat is classified as being empty, the
5/ indicator lamp will illuminate
when the engine is started and remain
illuminated, indicating that the passenger
front air bag is deactivated.


76 Safety and Security
Occupant safety
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
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, re-
main illuminated or go out. With the
5/ indicator lamp illuminated, the
passenger front air bag is deactivated. With
the 5/ indicator lamp out, the pas-
senger 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
5/ indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then go out, indicating that the
passenger front air bag is activated.If the 5/ indicator lamp is
illuminated, the passenger front air bag is
deactivated and will not be deployed.
If the 5/ indicator lamp is not
illuminated, the passenger front air bag is
activated and will be deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the head-thorax air
bags
If the passenger front air bag is deployed,
the rate of inflation will be influenced by:

the rate of relevant vehicle deceleration
as assessed by the air bag control unit

the passenger’s weight category as
identified by the Occupant Classification
System (OCS)
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant or child restraint 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 manufactur-
er’s instructions.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information:

Your vehicle is equipped with air bag
technology designed to turn off the pas-
senger front air bag in your vehicle when
the system senses the weight of a typi-
cal 12-month-old child or less along with
the weight of a standard appropriate
child restraint on the passenger seat.
