Warning and indicator lamps
General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Therefore, some indi-cator and warning lamps may light up or flash temporarily. This behavior is non-critical. Theseindicator and warning lamps only indicate a malfunction if they light up or flash after starting theengine or whilst driving.
