In this section you will learn the most
important facts about the restraint
systems of the vehicle.
The restraint systems are
Seat belts
Child restraints
Lower Anchors and Tethers for
CH
ildren (LATCH)
Additional protection potential provide
Supplemental Restraint System (SRS)
with
Air bags
Air bag control unit (with crash
sensors)
Emergency Tensioning Device
(ETD) for seat belts
Seat belt force limiter
Active head restraintsAir bag system components with
Front passenger front air bag off
indicator lamp
Front passenger seat with Occupant
C
lassification System (OCS)
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 =indicator lamp in the instrument
cluster (page 26) comes on when the
ignition is switched on and goes out no lat-
er than a few seconds after the engine has
been started.
The SRS components are in operational
readiness when the =indicator lamp is
not lit when the engine is running.
A malfunction in the system has been
detected if the =indicator 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

eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (

Warning!G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, Emergency Tensioning
Devices (ETDs), seat belt force limiters or air
bags) or their wiring, as well as tampering
with interconnected electronic systems, can
lead to the restraint systems no longer func-
tioning as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy inadvert-
ently or fail to deploy in accidents although
the deceleration threshold for air bag de-
ployment is exceeded. Therefore, never
modify the restraint systems. Do not tamper
with electronic components or their soft-
ware.
Warning!G
In the event that the =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 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.

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), side impacts (front
side impact air bags, rear side impact air
bags* and window curtain air bags) or roll-
overs (window curtain air bags). However,
no system available today can totally elimi-
nate 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 front passenger to always be in a
properly seated position and to wear their
respective seat belt.
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 it is properly
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 nearly upright
position with your back against the seat
backrest.
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 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 combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see 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 steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

Occupant safety
Always sit as upright as possible, prop-
erly use the seat belts and use an appro-
priately 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.
There is a possibility for a side impact air
bag related injury if occupants, especially
children, are not properly seated or re-
strained when next to a front side impact air
bag and/or rear 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) Always sit as upright as possible,
properly use the seat belts, and for all
children 12 years old and under, use an
appropriately sized infant restraint, tod-
dler restraint, or booster seat recom-
mended for the size and weight of the
child.
(2) Always wear seat belts properly.iAir bags are designed to deploy only in cer-
tain frontal impacts (front air bags), and in side
impacts (front side impact air bags, rear side im-
pact* air bags, and window curtain air bags)
which exceed preset thresholds, and in certain
rollovers (window curtain air bags). Only during
these events will they provide their supplemental
protection.
The driver and passengers should always wear
their seat belts. Otherwise it is not possible for
air bags to provide their supplemental protec-
tion.
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 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
the vehicle will continue to provide supplemental
crash protection for occupants.

Safety guidelines for the seat belt,
emergency tensioning device and
air bag
Warning!G
Damaged seat belts or seat belt 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 at an au-
thorized 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 dis-
posal guidelines. California residents,
see http://www.dtsc.ca.gov/Hazard-
ousWaste/Perchlorate/index.cfm.
Air bags and pyrotechnic emergency
tensioning devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced.
Do not pass seat belt 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, front passenger front air bag
cover, outboard sides of the 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 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
deployed.
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.
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.

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 air bag
2Front passenger front air bag
The front air bags are designed to provide
increased protection for the driver and
front passenger against the risk of injuries
to the head and thorax.
Driver and front passenger front air bag are
deployed:in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
if the system determines that airbag
deployment can offer additional pro-
tection to that provided by the seat belt
depending on whether the seat belt is
in use
independently of the front side impact
air bags, rear side impact air bags*
and/or the window curtain air bags.
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 your 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
tested and approved by Mercedes-Benz for
your vehicle model. Using other seat covers
may interfere with or prevent the
deployment of the front side impact air bags
or the rear side impact air bags. Contact an
authorized Mercedes-Benz Center for avail-
ability.
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the front passenger-side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 41).
The lighter the front passenger-side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.
