67 Instruments and controls
Temperature gaugeThe 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 210.
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 SID will display the message ”FILL
COOLANT FLUID”.
Pressure gaugeThe 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.
NOTEIf the needle, despite the above action,
enters the red zone, stop the car immedi-
ately.
If the needle stays in the red zone, turn off
the engine.
WARNING
Never open the coolant expansion tank
cap when the engine is hot. It contains hot
coolant under pressure. Failure to heed
this warning may result in personal injury.

The following CHECK messages may be
displayed: 1) This message will be displayed approximately
600 miles (1,000 km) before the next sched-
uled service is due, or when 365 days have
elapsed since the last service. The message
should be cleared at the time of that service
(see the Saab Warranties & Service Record
Booklet).
This message can also be deleted by first
briefly pressing the CLR button, then depress-
ing it a second time for at least eight seconds
until "SERVICE" appears on the display and a
chime sounds. The message can only be
deleted when it is shown on the SID.
Night panelTo improve night-driving conditions inside
the car, the Night Panel mode can be
selected. In this mode, the amount of infor-
mation displayed is reduced, and only the
most important instruments and displays
will be illuminated.
When the Night Panel button is pressed,
only the speedometer will be illuminated (up
to the 87-mph or 140-km/h graduation), all
the other instruments illumination will be
extinguished and their needles moved to
zero. Both the SID and the ACC displays will
be extinguished and the backlighting for
switches and other controls will be dimmed.
Note: All indicator and warning lights,
together with the display of CHECK mes-
sages, will operate as normal. The following conditions will wake up the
respective displays in the Night-Panel
mode:
 Setting of the Audio System, SID or ACC
(display comes on for ten seconds).
 CHECK message generated in the SID.
 High engine revs cause the rev counter to
be illuminated until the engine speed has
fallen again.
 If the quantity of fuel remaining falls below
4 gallons (15 liters), the fuel gauge will be
illuminated.
 If the engine temperature rises above nor-
mal, the temperature gauge will be illumi-
nated.
 If the speed of the car exceeds 84 mph
(135 km/h), the entire speedometer will
be illuminated.
 In cars with automatic transmission, if the
selector lever is moved from D to position
3, 2 or 1, the selector indication on the
main instrument panel will be illuminated.
To restore the displays and lighting to the
normal mode, press the Night-Panel button. Display shows: See

The system uses five sensors:
 Outside-air temperature.
 Cabin-air temperature.
 Sun sensor.
 Blended-air temperature (located in the
heater unit).
 Coolant temperature.
The sun sensor is centrally located on the
dashboard panel between the defroster
nozzles. Note that if anything is placed over
the sun sensor the ACC system will not
function properly.
Condensation water When the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form.

169 Starting and driving
Parking on a hillWhen parking on a steep hill, turn the front
wheels so that they will be blocked by the
curb if the car should move.
Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.  Wash and wax the car. Clean the rubber
seals on the hood, trunk lid and doors,
and lubricate them with glycerol (glyc-
erin).
 After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times. If the traf-
fic conditions allow, brake quite heavily
just before parking.
 Fill the fuel tank with fuel to prevent con-
densation forming in it.
 Top up the coolant and check the anti-
freeze before the onset of winter.
 Park the car in a dry, covered and
well-ventilated building. Leave the park-
ing brake OFF!
 Disconnect the negative (-) battery lead.
If freezing temperatures are likely to occur
during the long-term parking, remove the
battery and store it away from freezing
temperatures.
 Ideally, the car should be put up on
blocks, with the wheels off the ground. If
this is not possible, inflate the tires to
about 43 psi (300 kPa).
 Leave all the windows open a crack and
cover the car with a fabric tarpaulin - not
one made of plastic which will not breath.

1Pointing downhill and
against the curb
– Turn the wheels into the
curb and edge the car for-
ward until the wheels touch
the curb. 2Pointing uphill and
against the curb
– Turn the wheels away
from the curb and edge the
car back until the wheels
touch the curb. 3Pointing uphill or down-
hill – no curb
– Turn the wheels towards
the edge of the road. If the
car should start rolling, it
will not run into the road.

173 Starting and driving
Driving in hot weather Always check the coolant level before
starting a journey. When the engine is
cold, the coolant must not be above the
KALT/COLD mark on the expansion tank.
 At the end of a journey, if the engine has
worked hard, allow it to idle for two or
three minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. The engine temperature should
decrease. If the temperature continues
to rise with the engine idling, the engine
must be switched off. 2 If the engine is idling and the needle on
the temperature gauge falls, wait until a
normal temperature is shown (about in
the middle of the scale) before switching
off the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of coolant and water. Use
a Saab-approved coolant. If only water
is available, use that, but remember to
have the coolant mixture checked as
soon as possible.
3 As soon as possible, have the cooling
system checked by an authorized Saab
dealer.
Towing a trailerTrailer hitch attachment Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),
with trailer brakes, see also page 236.
Use only the electrical trailer hitch connec-
tor provided in the trailer hitch kit.
Saab recommends:
 Use a Saab original hitch kit attachment
which is designed and tested by Saab.
 Consult your Saab dealer for the right
hitch kit for your car.
WARNING
Always undo the expansion tank filler cap
carefully, releasing the pressure and any
vapor before removing the cap com-
pletely.
NOTEUse only a genuine Saab trailer hitch and
wiring, since other wiring methods can
cause expensive damage to the car’s
body and electrical system.
Consult an authorized Saab dealer for
guidance on how to connect the trailer
hitch electrical system.

175 Starting and driving
Recommendations for driving in
hilly terrainThe following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86°F (30°C).
The following time limits are based on the
capacity of the cooling system in hot
weather, i.e. approximately 104°F (40°C).It is important to consider the following when
driving a car with automatic transmission up
long inclines.
Use Normal mode when driving with a cara-
van or trailer on hilly roads. The adaptive
gear change pattern function will prevent
the transmission overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following may also occur:
 A/C compressor is switched off
 Gear change pattern is altered
 The CHECK message TRANSMISSION
OVERHEATING appears 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 message
has been extinguished. When driving sub-
sequent to the transmission oil overheating,
select either 3rd gear or Drive, whichever
will allow the engine to run at 3,000 rpm and
maintain the speed of traffic or a safe speed;
see page 159.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 considerationsAlways 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.

WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) 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
indicator” warning comes on, cease
towing until the problem has been recti-
fied.
