Although independent systems, their pro-
tective functions work in conjunction with
each other.
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The
1
indicator lamp in the instrument
cluster (
page 26) comes on when the
ignition is switched on and goes out no
later than a few seconds after the engine
was started.
The SRS components are in operational
readiness if the
1
indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1
indicator lamp:
ț
fails to go out not later than approxi-
mately 4 seconds after the engine was
started
ț
does not come on at all
ț

or while driving
