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 starting the engine or
whilst driving. 274
