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
As independent systems their protective
effects work in conjunction with each oth-
er.The 1 warning lamp in the instrument
cluster lights up for about 4 seconds when
you turn the key in the starter switch to
position1 or2 or press the KEYLESS-GO*
(if so equipped) start/stop button once or
twice. It goes out when you start the en-
gine. This shows that the restraint systems
are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately
4 seconds or if it comes on thereafter, a
malfunction in the system has been de-
tected.
More information can be found in the
"Practical hints" section (
page 290).
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).
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come at all, the SRS may not be operational.
For your safety, we strongly recommend
that you visit an authorized Mercedes-Benz
Center immediately to have the system
checked; otherwise the SRS may not be ac-
tivated when needed in an accident, which
could result in serious or fatal injury, or it
might deploy unexpectedly and unnecessar-
ily which could also result in injury.
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.
Work on the SRS must therefore only be per-
formed by an authorized Mercedes-Benz
Center.
