In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts (page 76)

Child restraints (page 82)

Lower Anchors and Tethers for
CHildren (LATCH) (
page 86)
Additional protection is provided by

Supplemental Restraint System (SRS)
with

Air bags (page 66)

Air bag control unit (with crash
sensors)

Emergency Tensioning Device
(ETD) for seat belts (
page 79)

Active head restraints (page 81)

Front passenger seat with Occupant
Classification System (OCS)
(
page 71)
Although independent systems, their pro-
tective functions work in conjunction with
each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The 1indicator lamp in the instrument
cluster lights up when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:

fails to go out after approximately
4 seconds after the engine was started

does not come on at all

comes on after the engine was started
or while driving

65 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 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 air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact 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.

66 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),
side impacts (side impact air bags and win-
dow curtain air bags) or rollovers (window
curtain air bags). However, no system avail-
able today can completely eliminate injuries
and fatalities.
The activation of the air bags temporarily re-
leases a small amount of dust from the
air bags. This dust, however, is neither inju-
rious to your health, nor does it indicate a
fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple 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 front passenger to always be in a
properly seated position and to wear their
respective 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.
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 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 air bag cover
on the steering wheel must be at least
10 in (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 contact 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 air bag inflates.

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

67 Safety and Security
Occupant safety

Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side impact air bag inflates. This could
result in serious injuries or death should
the air bag be triggered. Always sit as
upright as possible, properly use the
seat belts 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.Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side impact air bag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a side impact 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
side impact air bag inflates. This could
result in serious injuries or death should
the side impact air bag be deployed.
(2) Always sit as upright as possible, prop-
erly use the seat belts, and for children
12 years old and under, use an appropri-
ately sized infant restraint, toddler re-
straint, 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
rear seat occupants to have the rear mount-
ed side impact air bags deactivated, then
deactivation can be accomplished upon
your written request to do so at your autho-
rized 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.

68 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
Emergency Tensioning Device and
air bagiAir bags are designed to activate only in cer-
tain frontal impacts (front air bags, driver-side
knee bag), side impacts (side impact and window
curtain air bags) which exceed preset thresholds
and in certain rollovers (window curtain
air bags). Only during these events will they pro-
vide 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 pro-
tection.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not be deployed. 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 pro-
tection 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-
sengers 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. Use only
seat belts installed or supplied by an au-
thorized Mercedes-Benz Center.

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

Air bags and Emergency Tensioning De-
vices (ETDs) are designed to function on
a one-time-only basis. An air bag or 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 front air bag
cover, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

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.

69 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 air bags
1Driver’s air bag
2Passenger air bag
3Knee bag
Driver and passenger air bags are de-
ployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the side impact
air bags

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 the window curtain air bag is de-
ployed.

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.

Air bag system components will be hot
after an air bag 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 air bag
unit or Emergency Tensioning Device,
our safety instructions must be fol-
lowed. These instructions are available
from any authorized Mercedes-Benz
Center.

Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other, potentially more serious injuries
resulting from air bag deployment.
Warning!G
Only use seat covers which have been test-
ed 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 your au-
thorized Mercedes-Benz Center for availabil-
ity.
