Safety precautions

CAUTION!

When performing repair work, especially due
to the confined conditions in the engine well,
pay attention to the following:

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

Ensure sufficient clearance to all moving or
hot components.

For safety reasons, fuse No. 28 must be

removed from fuse holder before opening fuel
system because fuel pump can be activated by
door terminal switch in driver's door.
