General notes
Some systems carry out a self-diagnosis when the ignition is switched on. Several warning and indicator lamps can thereby temporarily light up or flash. This behaviour is non-critical. These
warning and indicator lamps only indicate a malfunction if they light up or flash after the engine is started or during a journey. Wa

ted can cause some fluids which may have leaked into the engine compart-
ment to catch fire.

can occur just by opening the bonnet.
There is a risk of injury.
