Warning!
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.

SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.
The SRS indicator lamp + in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than a few seconds after the engine has been
started.
The SRS components are in operational
readiness when the SRS indicator lamp
+ is not lit while the engine is running.

Warning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
