The rear seat head restraints can be folded
backward for increased visibility.
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint to support the back of
the head approximately at ear level.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
Warning!
G
For safety reasons, always drive with the
rear head restraints in the upright position
when the rear seats are occupied.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.!The center rear seat head restraint can-
not be adjusted.

Warning!
G
In the case of an accident liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
side rear view mirror or glance over your
shoulder before changing lanes. !Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state by applying plenty of water.

56 Safety and SecurityOccupant safety
Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are
Seat belts
Emergency tensioning device
Airbags
Child seats
Child seat recognition
Lower anchors and tethers for children
(LATCH)
As independent systems their protective
effects work in conjunction with each
other.The
1
warning lamp in the instrument
cluster (page 22) lights up:
for about four seconds when you turn
the key in the starter switch to
position1.
for about four seconds when you start
the engine by turning the key.The warning lamp goes out shortly after
you start the engine. This shows that the
restraint systems are operational.
A malfunction in the system has been
detected if the

warning lamp:
fails to extinguish after approximately
four seconds.
does not come on at all.
comes on after the engine was started
or while driving.
For safety reasons, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
More information can be found in the
“Practical hints” section (
page 257).
iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 65).

is turned to position2 and left there.
The warning lamp will go out when you
start the engine.
57 Safety and Security
Occupant safety
Airbags
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend 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.
Improper work on the restraint systems,
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 inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be
performed by an authorized Mercedes-Benz
Center.
Warning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, or side (side impact and head protec-
tion window curtain airbags) impacts which
may cause significant injuries. 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 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:
61 Safety and Security
Occupant safety
Driver and passenger airbags are deployed
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
7
indicator lamp in the center
console is not lit (
page 67)Side impact airbags, window curtain
airbags
3Side impact airbags
4Window curtain airbag
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 airbagsThe front passenger side airbag will only
deploy if the system senses that the front
passenger seat is occupied.
The side impact airbags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
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 and the driver‘s 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.
!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.

Special BabySmart
TM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are
required for use with the BabySmart
TM air-
bag deactivation system. With the special
child seat properly installed, the passenger
front airbag will not deploy.

After turning the key in the starter switch
to position1 or2, the7
indicator lamp
located in the center console lights up for
approx. six seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the passenger seat.
More information can be found in the
“Practical hints” section (page 260).
iThe system does not deactivate the
side impact airbag.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
front passenger airbag will not deploy only if
the
7
indicator lamp remains illuminat-
ed.
