65 Instruments and controls
Temperature 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 enters the red zone, the
warning light will come on and an alarm
chime will sound.
If the needle approaches the red zone,
which can occur in very hot weather or when
the engine is under a heavy load, drive in the
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 198.
If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level by looking at the
level visible through the plastic tank – do not
remove the cap.
If the coolant level falls below the MIN mark,
the Saab Information Display (SID) will dis-
play the message ”FILL COOLANT FLUID”.
Pressure gauge
The turbo gauge indicates the air volume for
combustion, which is equivalent to the
engine load.
At low loads, the needle will move within the
white zone. At higher loads and during
heavy acceleration, the needle will enter the
yellow area. At very high loads (certain var-
iants only) the needle may enter the first part
of the red zone without indicating that there
is a fault.
NOTICE
If the needle, despite the above action,
enters the red zone, stop the car immedi-
ately, let the engine idle.
If the needle stays in the red zone,
turn off
the engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cool-
ing-system can cause hot coolant and
steam to be released. Failure to heed this
warning may result in personal injury.
