Speedometer; Temperature Gauge - Saab 2003 9-3 Owner's Manual

60 Instruments and controls
Speedometer (U.S. speedometer
shown)
The speedometer displays the speed of the
car in miles per hour (mph). It receives infor-
mation about vehicle speed from the ABS's
wheel sensors.

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 goes into the red zone (which
can occur at high outside air temperatures
or under heavy engine loads), choose the
highest possible gear ratio and the lowest
possible engine speed, and avoid shifting
down.
NOTICE
If the needle, despite the above action,
enters the red zone, stop the car in a suit-
able place and allow the engine to idle. If
the needle continues to rise, switch off the
engine.
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 (see page 179).
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cooling-
system can cause hot coolant and steam
to be released. Failure to heed this warn-
ing may result in personal injury.
