Airb ags
Introduction
The installatio npoint of an ai rbag can be rec-
ognized by the AIR BAG symbol.
An ai rbag complements the correctl yfastened
sea tbelt. It is no substitute for the sea tbelt. The
ai rb ag provides additional protection in appli-
cable accident situations.
Not al lairbags are deployed in an accident. The
different ai rbag systemsf unctionindepend-
entlyf rom one another (

However, no system available toda ycan com-
pletel yeliminate injurie sand fatalities.
It is also not possibl etoruleo utariskofi njury

To avoid hazardous situations, alwaysmake
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sittin gcorrectly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RAdjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of
the head restraint must support the head at
about eye level.
RMove the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely.
ROnly hold the steerin gwheel on the outside.
This allows the air bag to be fully deployed.
RAlways lean against the backrest while driv-
ing. Do not lean forwards or lean against the
door or side window. You may otherwise be in
the deployment area of the air bags.
RAlways keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
RFor this reason, alwayss ecure persons less
than 5ft(1.50 m) tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If ac hild is traveling in your vehicle, also
observe the followingn otes:

Important safety notes
GWARNING
The air bag parts are hot after an air bag has
been deployed. There is arisk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at aqualified spe-
cialist workshop as soon as possible.
GWARNING
Ad eployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident .There is an increased
risk of injury.
Have the vehicle towed to aqualified special-
ist workshop in order to have adeployed air
bag replaced.
It is importan tfor your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air bags
continue to perform their protective function for
the vehicle occupantsint he event ofacrash.
GWARNING
Emergency TensioningD evices that have
deployed pyrotechnically are no longer opera-

ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
TensioningD evices replaced immediately at a
qualified specialist workshop.
If Emergency TensioningD evices are triggered
or air bags are deployed, you will hear abang,
and asmall amount of powder may also be
released. The 6restraint system warning

Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
ac hild restraint system on arear seat. Children
are generally better protected there.
If ac hild younger than twelve years old and
under 5ft(1.50m )inh eight is travelin ginthe
vehicle:
Ralwayss ecure the child in achild restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child
Rbe sure to observe the instruction sand safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.

When leaving the vehicle, alwaystake the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is arisk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is arisk of injury.
If you leave the vehicle, takin gthe child with
you, alwayse nsure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with ablanket ,for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.
Always ensure that all vehicle occupantsh ave
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(
Ypage 40) and the notes on correct use of seat
belts (Ypage 41).
Ab ooster seat may be necessary to achieve
proper seat belt positionin gfor children over
41 lbs (1 8kg)until they reach aheight where a
three-point seat belt can be properly fastened

Special seat belt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retrac- tor is disabled and the inertia real draws in a
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts except the driver's seat belt are
equipped with aspecial seat belt retractor.
When activated, the special seat belt retractor
ensures that the seat belt will not slacken once
the child restraint system has been secured.
Installing achild restraint system:
XAlways comply with the child restraint system
manufacturer's installation instructions.
XPull the seat belt smoothly out of the belt sash
guide.
XEngage the seat belt tongue in the belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear aratchetin gsound. The special seat belt
retractor is activated.
XPush the child seat restraint system down so
that the seat belt is tight and does not loosen.
Removing achild restraint system and deacti-
vating the special seat belt retractor:
XAlways comply with the child restraint system
manufacturer's installation instructions.
XPress release button of belt buckle, hold the
belt tongue firmly and guide it back towards
the belt sash guide.
The special seat belt retractor is deactivated.

that the base of the child restraint system is
alway sresting completely on the seat cush-

child restraint systems with the original cover
designed for them. Only replace damaged
covers with genuine covers.
