L
Note:
Turn in direction (1) for a richer mixture; the CO value
will rise towards its maximum value. Turning further
in direction (1) will not vary the CO value any further.
Turn in direction (3) for a leaner mixture; the CO val-
ue will drop to a minimum. Turning further in direc-
tion (3) causes the engine's emergency-run
programme to operate and has no influence on the
CO value.
e
Caution:
If the engine's emergency-run programme comes
into operation, fault 1111 will be memorised by the
engine control unit.
