Safety Precautions

WARNING:

Observe the following for all installations, especially in engine compartment due to lack of room:

  • Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
  • Watch for sufficient clearance to all moving or hot components.
  • Fuel system is under pressure! Before opening system, place rags around the connection point. Then release pressure by carefully loosening connection.

For safety reasons, fuses -13- and -14- (arrows) must be removed from the fuse holder before opening the fuel system since the Fuel Pumps (FP) can be activated via the door contact switch of the driver's door.
