WARNING
•
The cooling fan (located at the front of
the engine compartment, behind the radi-
ator) may start or continue to operate (for
up to 6 minutes) after the engine has
been switched off.
•
Engine cleaning should only be done by a
workshop. If engine cleaning agents are
used when the engine has been running,
there may a fire risk.
•
Before performing any operations in the
engine compartment, the ignition should
always be completely switched off (in
mode
0
) and there should be no remote
keys in the passenger compartment. The
gear selector should be in the
P
(park)
position. If the engine has been running,
wait until it has cooled before touching
any components in the engine compart-
ment.
•
The distributor ignition system operates
at very high voltages. Special safety pre-
cautions must be followed to prevent
injury. Always turn the ignition off when
replacing distributor ignition components
e.g. plugs, coil, etc.
•
Do not touch any part of the distributor
ignition system while the engine is run-
ning. This may result in unintended move-
ments and body injury.
