Safety precautions

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:

• Do not touch or disconnect the ignition wires when the engine is running or turning at starting RPM.
• Always switch the ignition off before disconnecting or reconnecting the wires for the injection and ignition system, including the high voltage wiring and test leads.
• If the engine is to be cranked at the starting RPM without starting (e.g. for compression testing), disconnect the electrical connector from the ignition coils and the fuel injectors.
• Always switch the ignition off before cleaning the engine.

• Be sure to activate the vehicle features (radio/radio-navigation system, clock, electric window regulators) according to the owners manual when the battery is reconnected.
• Switch the ignition off and remove the ignition key.
