Saab 2005 Automobile User Manual


 
60 Instruments and controls
Check fuse 1 (radiator fan) in the fuse panel
under the hood, see page 215.
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
”Coolant level low.
Refill.”.
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 or under cer-
tain barometric conditions, the needle may
enter the first part of the red zone without
indicating that there is a fault.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power, because the monitoring system is
holding the charging pressure down, you
should contact an authorized Saab dealer.
If the speed exceeds 149 mph/240 km/h
(155 mph/250 km/h, 9-5 Aero) the increase
in speed will be limited by the lowering of the
boost pressure. The pressure gauge then
moves towards the middle of the orange
zone, indicating reduced engine output and
thus reduces the speed of the car as well.
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, stop
the engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the coo-
ling-system can cause hot coolant and
steam to be released. Failure to heed this
warning may result in personal injury.
