Warning and indicator lamps in the instrument cluster
General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Therefore, some
indicator and warning lamps may light up or flash temporarily. This behavior is non-critical.
These warning and indicator lamps only indicate a malfunction if they light up or flash after the
drive system is started or during a journey.
