Explanation of scheduled maintenance items
WARNING
Diesel only
Never work on the injection system
with the engine running or within 30
seconds after shutting off the
engine. High pressure pump, rail,
injectors and high pressure pipes are
subject to high pressure even after
the engine stops. The fuel jet pro -
duced by fuel leaks may cause seri -
ous injury, if it touches the body.
People wearing a cardiac pacemaker
should maintain a distance of at
least 30cm from the ECU or wiring
harness within the engine room
whilst the engine is running, since
the high currents in the Common
Rail system produce considerable
magnetic fields.

petrol engine)
The vapour hose and fuel filler cap
should be inspected at those inter -
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor -
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi -
dence of heat and/or mechanical
damage. Hard and brittle rubber,
