Pressure Gauge - Saab 2006 9-5 Owner's Manual

66 Instruments and controls
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.
Check fuse 1 (radiator fan) in the fuse panel
under the hood, see page 223.
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.".
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.

Pressure gauge

The turbo gauge indicates the air volume for
combustion, which is equivalent to the
engine load.
Under certain barometric conditions, the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power because the monitoring system is
limiting boost pressure, you should contact
a workshop immediately. We recommend
that you contact an authorised Saab work-
shop.
