Important safety notes
G WARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, con-
tact an authorized Mercedes-Benz Center for
details. USA only: for further information con-
tact our Customer Assistance Center at
1-800-FOR-MERCedes (1‑800‑367‑6372).
Restraint system warning lamp
The restraint systems functions are checked
after the ignition is switched on and at regular
intervals when the engine is running. This
allows malfunctions to be detected in good
time.
When the ignition is switched on, the 6
restraint system warning lamp in the instru-
ment cluster lights up. It goes off again a few
seconds after the engine is switched on at the
latest. The components of the restraint sys-
tem are on standby.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on.
R
does not go out after a few seconds when
the engine is running.
R lights up again when the engine is running.
G WARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer-
gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
