59 Safety and Security
Occupant safety
Airbags
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 visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily 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 airbag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
Warning!
G
Airbags are designed to reduce the potential
of injury and fatality in certain frontal im-
pacts (front airbags), side impacts (side im-
pact airbags and head protection window
curtain airbags) or rollovers (head protec-
tion window curtain airbags). However, no
system available today can totally eliminate
injuries and fatalities.
The activation of the airbags temporarily re-
leases 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 airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and passenger front to always be in a
properly seated position and to wear your
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 ensure that it is
properly positioned on your body.
Since the airbag 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 airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:

Sit properly belted in a nearly upright
position with your back against the seat
backrest.


60 Safety and SecurityOccupant safety

Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least 10 in
(25 cm) or more. You should be able to
accomplish this by a combination of ad-
justments to the seat and steering
wheel. If you have any problems, please
see an authorized Mercedes-Benz Cen-
ter.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.


Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.


Occupants, especially children, should
never lean their heads in the area of the
door where the side airbag inflates.
This could result in serious injuries or
death should the airbag be triggered. Al-
ways sit nearly upright, properly use the
seat belts and appropriate size infant or
child restraint system.


Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front airbag when it
is properly installed. Otherwise they will
be struck by the airbag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is extremely impor-
tant that you make the buyer aware of this
safety information. Be sure to give the buyer
this Operator's Manual.
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag.
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag 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
side airbag inflates. This could result in


61 Safety and Security
Occupant safety
serious injuries or death should the side
airbag be activated.
(2) Always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or child restraint system for
all children 12 years old or under.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have the rear mount-
ed side airbags deactivated, then deactiva-
tion can be accomplished upon your written
request to do so at your authorized
Mercedes-Benz Center at an additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
iAirbags are designed to activate only in
certain frontal (front airbags) impacts,
side impacts (side impact and head
protection window curtain airbags)
which exceed preset thresholds, and in
certain rollovers (head protection win-
dow curtain airbags). Only during these
events will they provide their supple-
mental protection.
The driver and passengers should al-
ways wear their seat belts. Otherwise it
is not possible for airbags to provide
their supplemental protection.
In case of other types of impacts and
impacts below airbag deployment
thresholds, airbags will not be activat-
ed. The driver and passengers will then
be protected to the extent possible by
a properly fastened seat belt. A proper-
ly fastened seat belt is also needed to
provide the best possible protection in
a rollover.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
for your safety and that of your passen-
gers that you replace deployed airbags
and repair any malfunctioning airbags
to ensure that the vehicle will continue
to provide supplemental crash protec-
tion for occupants.

62 Safety and SecurityOccupant safetySafety guidelines for the seat belt,
emergency tensioning device and
airbagWarning!
G


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


Airbags and pyrotechnic emergency ten-
sioning devices (ETDs) are designed to
function on a one-time only basis. An
airbag or ETD that was activated must
be replaced. PRE-SAFE has electrically
operated reversible pre-tensioners in
addition to the pyrotechnic ETDs.


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


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


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


Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain airbag is deployed.


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.


An airbag system component within the
steering wheel gets hot after the airbag
has inflated. Do not touch.


In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air-
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.


For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.


Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.

63 Safety and Security

When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
Front airbags

independently of the side impact air-
bags
The airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The passenger front airbag will only be de-
ployed if:

!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system's deployment threshold.
