Safety precautions
Note the following if testers and measuring instruments have to be used during a road test:
  WARNING
Accidents can be caused if the driver is distracted by test equipment while road-testing, or if test equipment is not properly secured.
Persons sitting in the front passenger's seat could be injured if the airbag is triggered in an accident.
l  The use of test equipment while driving causes distraction.
l  There is an increased risk of injury if test equipment is not secured.
Test equipment must always be secured on the rear seat with a strap and operated from the rear seat by a second person.
To prevent injuries to persons and/or irreparable damage to the fuel injection and ignition system, the following must be noted:
t  Always switch off the ignition before connecting or disconnecting injection or ignition system wiring or tester cables.
t  If you want to crank the engine at starting speed without actually starting it (e.g. compression test), first unplug the connectors from the ignition coils and the injectors.
t  Certain tests may lead to a fault being detected by the control unit and stored. The event memory should therefore be interrogated and (if necessary) erased after completing the tests and any repair work that may be required.
t  Always switch off the ignition before cleaning the engine.
t  Always switch off the ignition before connecting or disconnecting the battery, otherwise the engine control unit may be damaged.
  WARNING
The fuel system is pressurised. Before opening the system place a cloth around the connection. Then release pressure by carefully loosening the connection.
