WARNING | When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions: |
| All the various lines (e.g. fuel, hydraulic system, active carbon filter system, coolant, refrigerant, brake fluid and vacuum pipes and hoses) and electrical wiring must be installed in their original positions. |
| Ensure sufficient clearance for all moving or hot components. |
|
| Note the following if testers and measuring instruments have to be used during a road test: |
| l
| Always install the test and measurement equipment in the back seat of the vehicle so that they may be used by a second mechanic |
| l
| If test and measuring instruments are operated from front passenger's 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 avoid injury to personnel and/or damage to the preheating and injection system, the following points should be observed: |
| l
| Remove and connect all cable for the preheating and injection system, including the cables for the test equipment only with the ignition OFF |
| l
| If the engine is to be rotated using the starter but without starting it, for example: for testing compression, the connector of the injection pump on the cylinder head must be disconnected |
| l
| If there is an anti theft code radio, check the code before disconnecting the battery |
| l
| The battery may only be removed and connected with the ignition off; if not, the control unit for the direct diesel injection system may be damaged |
