The ignition system has very high voltage and output. The voltage in the ignition system is highly dangerous. The car's electrical system must always be in key position 0 when work is being performed in the engine compartment; see Key positions - functions at different levels.

Do not touch the spark plugs or ignition coil when the car's electrical system is in key position II or when the engine is hot.
