| 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. |
| Injuries can also be caused if the passenger's airbag is triggered in a collision. |
| 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. |
|
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 and electrical wiring so that they are in their original positions. |
| t
| e.g. for fuel, hydraulics, activated charcoal filter system, coolant and refrigerant, brake fluid, vacuum. |
| t
| Ensure that there is sufficient clearance to all moving or hot components. |
|
| To avoid any risk of injuries to persons and/or damage to the injection and glow plug system, always observe the following safety precautions: |
| t
| Persons wearing a pacemaker should not lean over the engine compartment while the engine is running, as the injectors use high voltage pulses. |
| t
| Fuel lines may not be opened if the engine is running. |
| t
| Always switch off the ignition before connecting or disconnecting injection and glow plug system wiring or tester cables. |
| t
| Always switch off ignition before cleaning engine. |
| t
| Only disconnect and connect the battery with the ignition switched off, otherwise the engine control unit may be damaged. |
| 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. |
