  WARNING
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant and refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
t  Ensure that there is sufficient clearance to all moving or hot components.
Note the following if testers and measuring instruments have to be used during a road test:
t  Test and measuring instruments must always be secured to rear seat and operated by a second person from this location.
t  If test and measuring instruments are operated from front passenger seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.
To prevent injuries to persons and/or destruction of the injection and glow plug system, the following must be noted:
t  The ignition must be switched off before connecting or disconnecting injection or glow plug system wiring or tester cables.
t  If the engine is to be turned at starter speed, without starting, e.g. when checking compressions, disconnect unit injector connector on cylinder head.
t  Before disconnecting battery, obtain radio code for radios with anti-theft coding.
t  Disconnecting and connecting the battery must only be done with the ignition switched off, as otherwise the control unit for diesel direction injection system could become damaged.
