Safety Precautions

If special testing equipment is required during road test, note the following:

Distraction and improperly secured test equipment can lead to accidents.

There is a risk that the passenger airbag could deploy in a collision.

• Operating testing and measuring equipment while driving creates a distraction.

• There is an increased risk of injury due to unsecured testing and measuring equipment.

• Always secure testers on the rear seat with a strap and have a second person on the rear seat operate them.

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

• Individuals with a pacemaker must not stay in the danger area of high voltage systems, for example ignition system, xenon light.

• Do not touch or remove ignition wires when engine is running or turning at starter speed.

• Always switch ignition off before disconnecting or reconnecting wires for the ignition system, including high voltage wiring and test leads.

• If engine is to be cranked at starting RPM without starting (for example for compression testing), disconnect connectors from ignition coils and from fuel injectors. After performing work, check and erase DTC memory.

• Cleaning the engine should only be performed with ignition switched off.

Risk of destroying electrical components when battery is disconnected.

• Observe measures when disconnecting battery.

• Only disconnect battery with ignition switched off.
