Safety precautions

WARNING! Make sure the ignition is switched OFF before:

^ Disconnecting the ignition wires.
^ Disconnecting the fuel injection system wiring.
^ Connecting or disconnecting test equipment leads.
^ Washing the engine or engine compartment.


CAUTION: Before disconnecting the battery:
^ Stop the engine.
^ Determine the correct coding for the antitheft radio.
^ Switch the ignition off (also applies when connecting the battery). Failure to do so may damage the Engine Control Module (ECM).

CAUTION! Whenever working on the fuel supply or the fuel injection systems, always observe the following rules of cleanliness:
^ Thoroughly clean the fuel system lines and hose connections and the surrounding area before disconnecting.
^ Place removed components on a clean surface and cover. Use plastic sheeting or paper. Do not use fluffy rags that could leave lint.
^ Install only clean components. Do not remove replacement parts from the packaging until immediately before installing them. Do not use parts that have been stored without packaging e.g. in toolboxes, etc.
^ Avoid working with compressed air when the fuel system is open.
^ Avoid moving the vehicle when the fuel system is open.
^ Replace all fee wraps that were cut and install them in the same location from where they were removed.
