Warning and indicator lamps on the
instrument cluster
General notes
Some systems carry out a self-diagnosis when
the ignition is switched on. A number of warning
and indicator lamps might temporarily light up
or flash during this. This behaviour is non-criti-
cal. These warning and indicator lamps indicate
a malfunction only if they light up or flash after
the engine is started or during a journey.
