As independent systems, their protective
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 = indicator lamp in the instrument
cluster (
page 28) comes on when the
ignition is switched on and goes out no lat-
er than a few seconds after the engine has
been started.
The SRS components are in operational
readiness when the = indicator lamp is
not lit when the engine is running.
A malfunction in the system has been
detected if the = 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 comes on after the engine was started
or while driving

to the restraint systems no longer function-
ing as intended.
