Instruments and controls
If the needle approaches the red zone,
whichcanoccurinveryhotweatherorwhen
theengineisunderaheavyload,driveinthe
highest gear possible, keep the engine revs
low and avoid shifting down.
Check fuse 3 (radiator fan) in the fuse panel
under the hood, see page 191.
If theneedlerepeatedlyenterstheredzone,
stop thecar as soonas it issafe to do soand
check the coolant level by looking at the
level visible through the plastic tank - do not
remove the cap.
NOTE
Temperature gauge
Pressure gauge
The temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle, despite the above action,
enters the red zone, stop the car immedi-
ately.
The pressure gauge indicates the pressure
in the induction manifold. Under low load
and while the engine is braking there will be
vacuum in the induction manifold.The
needleofthepressure gaugewillthenmove
within the white zone. At higher engine
speeds and higher loads, the turbo-com-
pressor produces an overpressure in the
induction manifold. The needle will then
enter the orange zone. Normally the needle
should not enter the red zone, since a mon-
itoring system sets limits to the charging
pressure and protects the engine.
If the needle stays in the red zone, stop
the engine.
If the needle enters the red zone, the
warning light will come on and an alarm
chime will sound.
If the coolant level falls below the MIN mark,
the SID will display the message ”FILL
COOLANT FLUID”.
WARNING
Never open the coolant expansion tank
capwhen theengineis hot.It contains hot
coolant under pressure. Failure to heed
this warning may result in personal injury.
