Safety
Restraint systems
Restraint system warning lamp
The 1 restraint system warning lamp in
the instrument cluster lights up:
for approximately four seconds when
you turn the ignition to position 1
52
This indicates that the restraint systems
are operational.
continuously when you turn the ignition
to position 2
This indicates that the 1 restraint
system warning lamp is operational.
The SRS system performs regular selfchecks
while the engine is running. This
means that faults can be detected in good
time.
Risk of injury G
There is a fault if the 1 restraint system
warning lamp does not light up when you
switch on the ignition, does not go out a few
seconds after the engine is running or lights
up again. Some systems may be activated
inadvertently or not at all in the event of a
collision. If this occurs, have the SRS system
checked and repaired immediately at a qualified
specialist workshop which has the necessary
specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use a Mercedes-Benz
Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out
at a qualified specialist workshop.

Activation of the belt tensioners, belt
force limiters and airbags
In the event of a collision, the sensor in
the airbag control unit evaluates important
physical data, such as duration, direction
and degree of vehicle deceleration or acceleration.
Based on the evaluation of this
data and depending on the vehicle's rate of
longitudinal deceleration in a collision, the
belt tensioners are the first to be triggered
by the airbag control unit. The front airbags
are not triggered until a second activation
threshold is reached, i.e. an even higher
rate of vehicle deceleration in the longitudinal
direction is exceeded.
