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. |
|
| To prevent injuries to persons and/or destruction of the injection and glow plug system, the following must be noted: |
| t
| Connect and disconnect wiring of glow plug and injection system only with ignition switched off (includes test 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. |
| 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. |
| 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. |
