Airbags
Warning!
G
In the event that the
1
malfunction indi-
cator lamp lights up during driving or does
not come on at all, the SRS may not be op-
erational. For your safety, we strongly rec-
ommend 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 inju-
ry.
Improper work on the restraint systems, in-
cluding incorrect installation and removal,
can lead to possible injury through an unin-
tended activation of the SRS.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.

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 SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma 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 front passenger 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 an upright position
with your back against the seat back-
rest.

56 Safety and SecurityOccupant safety

Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration 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 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.


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. Always
sit upright, properly use the seat belts
and appropriate size infant or child re-
straint 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 you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
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

57 Safety and Security
Occupant safety
serious injuries or death should the side
airbag be activated.
(2) Always sit upright, properly use the seat
belts and use an appropriately sized in-
fant or child restraint system for all chil-
dren 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 both rear side
airbags deactivated, then deactivation 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 impacts (front air bags),
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 passenger 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 the safety of your
passengers that you replace deployed
airbags and repair any malfunctioning
airbags to ensure that the vehicle will
continue to provide supplemental
crash protection for occupants.

58 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 ETDs are designed to func-
tion on a one-time-only basis. An airbag
or emergency tensioning device (ETD)
that was activated must be replaced.


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, front passenger airbag cov-
er, 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 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.


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


Improper work on the system, including
incorrect installation and removal, can
lead to possible injury through an unin-
tended activation of the SRS.


In addition, through improper work
there is a risk of rendering the SRS inop-
erative or causing unintended airbag de-
ployment. Work on the SRS must
therefore only be performed by an au-
thorized 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.

59 Safety and Security
Occupant safety
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
Driver and passenger airbags are de-
ployed:

in the event of a frontal impact


if impact exceeds a preset deployment
threshold


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 front passenger airbag will only be de-
ployed if:


the front passenger seat is occupied.


the PASSENGER AIRBAG OFF indicator
lamp in the center console is not lit
(page 65).


the impact exceeds a preset deploy-
ment threshold
1Driver’s airbag
2Passenger airbagSide impact airbags, window curtain
airbags
The side impact airbags and window cur-
tain airbags are deployed:


on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
In addition, the window curtain airbags 1
are deployed:


in certain vehicle rollovers
The side impact airbags2and3 are not
deployed in impacts which do not exceed
the system’s deployment threshold.!Do not place objects heavier than 20
lbs (9 kg) on the front passenger seat.
This could cause the front or side im-
pact airbag on the front passenger side
to deploy in a crash which exceeds the
system's deployment threshold.

60 Safety and SecurityOccupant safetyThe front passenger side impact airbag 2
will only deploy if the system senses that
the front passenger seat is occupied.
The window curtain airbags fill up the area
between the A and C pillars (see arrows).

Seat belts
The seat belt nonusage warning lamp
<

in the instrument cluster lights up and a
warning sounds for a short time when you
turn the key in the starter switch to
position2 or press the KEYLESS-GO*
start/stop button twice and the drivers
seat belt is not fastened.
After starting the engine, the seat belt non-
usage warning lamp blinks for a brief peri-
od to remind the driver and passengers to
fasten the seat belts.
The use of seat belts and infant and child
restraint systems is required by law in
most states, the District of Columbia and
all Canadian provinces. Even where this is
not the case, all vehicle occupants should
have their seat belts fastened at all times
when driving or riding in the vehicle.
Information on fastening seat belts is
found in the “Getting started” section
(
page 40).

traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
