57 Instruments and controls
Speedometer (U.S. speedometer
shown)The speedometer receives signals from the
wheel sensors in the ABS system.
If the NIGHT PANEL mode has been
selected, the scale will be illuminated up to
87 mph (140 km/h). The remainder of the
scale will be illuminated if the speed of the
car exceeds 84 mph (135 km/h).
Fuel gauge Fuel-tank capacity, 18.5 US gal. (70 liters).
The fuel gauge shows the amount of fuel left
in the tank. When this is down to about
2.5 gal. (10 liters), a warning light on the
main instrument panel will come on (see
page 53).
Use the Saab Information display (SID) to
check the approximate distance that can be
traveled on the remaining fuel
(see page 59).
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 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.
If the needle enters the red zone, the
warning light will come on and an alarm
chime will sound.

175 Starting and driving
Use Normal mode when driving with a trailer
or trailer on hilly roads. The adaptive gear
change pattern function will prevent the
transmission from overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following can also occur:
the A/C-compressor can be shut off
the gear-change pattern is changed
the CHECK message TRANSMISSION
OVERHEATING can appear on the SID
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so and wait until the warning
has been extinguished. When continuing
your journey, select a locked gear (1, 2 or 3)
that will allow you to drive at an engine
speed of about 3,000 rpm (see page 161). Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a trailer, as this will increase fuel con-
sumption and risk overheating the transmis-
sion.
Driving considerations Always take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also ”Driving with a load” page 178.
If the car is equipped with automatic trans-
mission, select position L when ascending
or descending steep hills.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. As
regards single-axle trailers, whenever pos-
sible, concentrate the load over the wheels
and keep it as low as possible.
The trailer should be loaded so that the
maximum load on the towbar ball is 5% to
7% of the trailer weight with a maximum per-
missible tongue weight of 165 lbs. (75 kg).
Note that this load must be added to the total
load for the car. If this now exceeds the
specified load capacity, the load in the lug-
gage compartment will have to be reduced
by a corresponding amount.
WARNING
Remember to use engine-braking (selec-
tor position L, 3, or 4) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!
NOTEIf the ”Automatic transmission, fault indi-
cator” indicator comes on, cease
towing until the problem has been recti-
fied.
