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 indicator and warning lamps only indicate
a malfunction if they light up or flash after start-
ing the engine or whilst driving. Safety
