  Caution
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
t  To avoid damage to lines, ensure sufficient clearance to all moving or hot components.
–  First check whether a coded radio is fitted. If so, obtain anti-theft coding.
–  With ignition switched off, disconnect earth strap from battery.
