Safety precautions

To prevent injuries to persons and/or damage to the fuel injection and ignition system, the following must be noted:

CAUTION: When doing any repair work, especially in the engine well, due to the cramped conditions, pay attention to the following:

Route all sorts of lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum lines and hoses) and electrical wiring so that the original positions are restored.

Ensure sufficient clearance to all moving or hot components.

Do not touch or disconnect ignition wiring when the engine is running or being turned at starter speed.
The ignition must be switched off before connecting or disconnecting injection or ignition system wiring or tester cables.
If the engine is to be turned at starter speed, without starting, e.g. when checking compressions, pull connector off output stage:

NOTE:

Removing fuse 32 interrupts the voltage supply to the injectors.

Observe following if test and measuring instruments are required during a test drive:

Test and measuring instruments must be secured to rear seat and operated by a 2nd person from this location.

If test and measuring instruments are operated from front passengers 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.
