Initially, when the electronic key is turned from steering
lock position 0 to positions 1 or 2, malfunctions in the
crash-sensor are detected and indicated (the SRS
indicator lamp stays on longer than 4 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Center immediately.
In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.
Front airbags
The driver and front passenger front airbags are
designed to activate only in certain frontal impacts
exceeding a preset threshold.
The front passenger airbag deploys only if the front
passenger seat is occupied and the indicator lamp on
the center console is not illuminated.
Note:
Objects heavier than 20 lbs (9 kg) on the front
passenger seat can appear to the SRS to indicate the
presence of an occupant in that seat which causes the
passenger front airbag to deploy in a crash exceeding
the appropriate threshold.
Warning!
In the event a malfunction of the SRS is indicated
as outlined above, 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 activated when needed in an
accident, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in injury.
