6 Rear foglamp circuit
The rear foglamp circuit has been revised on all cars,
except those built to the USA, Canadian, Australian and
Japanese specification where foglamps are not included.
The rear foglamps are controlled from a switch panel
incorporating a warning light, which is illuminated when
the foglamps are switched on. The switch panel is
situated in the lower facia.
The rear foglamps will only illuminate when the foglamp
switch is in the 'ON' position, and side lamps or dipped
headlamps are in use. Switching to main beam will
extinguish the rear foglamps.

This change is applicable to all cars.
The compressor electrical circuit is now permanently
earthed so that it is always operating provided that:

2 The ambient temperature is above o
0
c.
3 The air conditioning unit function switch is not in
the

0FF' position.
This change has been introduced to reduce the possibility
of interior windscreen misting under adverse· conditions.
Exhaust gas recirculation cut-out control
This change only applies to cars built to USA, Canadian,
Australian and Japanese specification.
The switch, mounted on the carburetter assembly, which
cuts out the exhaust gas recirculation system under full
throttle conditions has been deleted.
The exhaust gas racirculation system is now cut out under
full throttle conditions by the kickdown switch.
