WARNING
Risk of burns.
Parts of the exhaust system may be hot.

When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant and refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
To avoid damage to lines, ensure sufficient clearance from all moving or hot components.
Cut through cable ties carefully and reinstall them in the same position.
