50 Instruments and controls
Indicator and warning
lights A number of indicator and warning lights will
come on when the ignition is switched on
prior to starting. Under normal conditions,
these should go out a few seconds after the
engine has started (see page 56).
Warning, oil pressure
(engine oil)
This light will come on together with if
the engine oil pressure is dangerously low.
If the light flashes or comes on while you are
driving, stop the car, switch off the engine
and check the engine oil level (see page
193). NOTEUnder no circumstances must the car be
driven when the warning light is on. Low
oil pressure can result in serious engine
damage.

148 Starting and drivingIt is possible for air to enter the lubricating
system in conjunction with an oil or oil-filter
change, or if the car has been stored for
some time. This air can cause the hydraulic
cam followers to emit a ticking noise, which
can persist for up to 15 minutes after start-
ing. Although this is quite normal and does
not indicate any malfunction, it is advisable
not to exceed 3,000 rpm before the noise
has disappeared.
The hydraulic cam lifters are completely
service free; the valve clearance is set up at
the factory and will not need any subse-
quent adjustment.
Starting the engineAvoid racing the engine or putting a heavy
load on it before it has warmed up. Drive
away as soon as the oil warning light has
been extinguished to enable the engine to
attain its normal temperature as quickly as
possible.
The engine has an automatic choke and
should be started as follows:
Cars with manual transmission
To start the engine the clutch pedal must
be fully depressed.
1 Depress the clutch pedal fully but do not
touch the accelerator.
2 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds. Wait
20-30 seconds before running the
starter again, to give the battery time to
recover.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2-3 minutes after starting. Cars with automatic transmission
1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
3 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds. Wait
20-30 seconds before running the
starter again, to give the battery time to
recover.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.
Useful tips on cold climate starting If the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
Now start the engine in the normal way – do
not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.  The tail pipe of the exhaust system
can become very hot during driving.
Bear this in mind when loading and
unloading the car.
 Do not rest or sleep in the car when
parked with the engine running. There
is a risk of depressing the accelerator
which could lead to engine damage.

152 Starting and drivingRefueling
Only fuel from well-known oil companies
should be used.
All Saab gasoline engines can be driven on
fuel of grade AON 87-93.
For optimum performance we recommend:
AO N 90 for 4-cylinder engines
AO N 93 for 3.0t V6 and 2.3T Aero, (see
page 250).
If fuel containing a mixture of alcohol is
used, the following restrictions apply:
Methanol: max. 5% by volume.
Ethanol: max. 10% by volume.
MTBE: max. 15% by volume.
The fuel filler cap is located in the right rear
quarter panel.
Switch off engine.
Open fuel door
Insert the fuel-pump nozzle beyond the
flange on the filler pipe. Do not withdraw the
nozzle while fueling is in progress. Stop refueling the first time the pump
turns off, indicating the tank is full.
Fuel-tank capacity: 18.5 US gal. (70 liters)
Screw on the filler cap and keep turning until
it has clicked at least three times.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank well filled.
Before the onset of freezing temperatures in
winter, it may be advisable to add gasoline
anti-freeze to the fuel a few times to dispel
any condensation in the system.
WARNING
 Never use fuel for any purpose other
than as engine fuel.
 Fuel is highly flammable and can
cause severe burns. Never use an
open flame in the vicinity of gasoline
and do not smoke when refuelling.
 Do not use the phone when refueling .
Gasoline fuels are highly explosive.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed.

160 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping trailer in hilly
country, with the wrong gear selected,
resulting in abnormally frequent gear
changing. Try selecting position L, 3 or 4.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 173).
Driving on hilly roads with a heavy
loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads with the
wrong gear is selected, resulting in many
extra gear changes. To avoid the transmis-
sion fluid overheating, always drive in
Normal mode. The adaptive gear change
patterns are then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid. Contact an authorized Saab
dealer (see also page 173). Towing Towing of cars with automatic transmission,
see page 180.
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 5th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position L.
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!
ProCarManuals.com

162 Starting and drivingIf the gear selector lever is moved from position D to L, a
change-down to 4th gear will occur at about 110 mph (180 km/h).
It will then change-down to 3rd gear at 80 mph (130 km/h), to 2nd
gear at 45 mph (75 km/h) and 1st at 20 mph (35 km/h).
Manual gear-changing is not recommended on slippery roads.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load and the present temperature of the transmis-
sion. The function is available in Normal and Sport modes.
The changes occur at a higher engine speed and the car remains in
the same gear for longer, if the transmission control module senses
that the load has not decreased. These gear-change patterns pre-
vent unnecessary changing up and down, when for example driving
up long slopes with a trailer or caravan, and to prevent overheating
the transmission oil. The adaptive gear-change function is also
selected automatically when the transmission oil becomes too hot,
to protect the transmission itself from damage and to lower the oil
temperature.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced so much that the function is no longer
required.
 ”Automatic transmission, fault indicator” appears on main
instrument panel, see page 159. L
Select position L if you wish to drive in 1st or 2nd
gear. This provides maximum engine braking.
The transmission shifts down from 2nd to 1st if
the speed of the car drops below 20 mph
(35 km/h).
NOTE Do not move the selector to position 4 at speeds in excess of
90 mph (150 km/h).
 Do not move the selector to position 3 at speeds in excess of
70 mph (110 km/h).

193 Car care and technical information
Engine oilChecking the oil level Check the engine-oil level regularly. This
should be done after the engine has been
run to normal temperature and then allowed
to cool for 2–5 minutes, with the car stand-
ing on level ground. Remove the dipstick
and wipe it clean before checking the level.
4-cylinder engine The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recom-
mended grade via the dipstick tube.
3.0t V6 engine The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recom-
mended grade via the dipstick tube.

194 Car care and technical informationOil changingThe engine oil must be changed in accor-
dance with the service program, see page
244.
Oil volume and grade, see page 251.
Oil changing should be carried out on a
warm engine.
1 Unscrew the drain plug in the bottom of
the sump and leave the oil to drain into
an oil tray or other suitable receptacle for
at least ten minutes. Take care, as the oil
may be hot.
2 After the oil has been drained, unscrew
and remove the oil filter.
3 Fit a new filter and tighten it by hand.
4 Refit the drain plug with a new washer.
5 Fill with new engine oil.
Run the engine to normal temperature and
check the oil level.
NOTEChange of engine oil and oil filter may be
required more frequently (5000-mile
intervals (8,000 km)) if any one of the fol-
lowing conditions apply to the car:
 Most trips are less than 5 to 10 miles (8
to 16 km). This is particularly important
when outside temperatures are below
freezing.
 Most trips include extensive idling
(such as frequent stop-and-go driving).
 Most trips are through dusty areas.
 You frequently tow a trailer or use a car-
rier on top of your vehicle.
 If the vehicle is used for delivery ser-
vice, police, taxi or other commercial
applications.

195 Car care and technical information
Transmission fluidManual transmission Check and top up the fluid in accordance
with the service program.
If original fluid cannot can be obtained for
topping up (see page 254), automatic trans-
mission fluid Dextron III (synthetic fluid) can
be used. If so, the car should be taken to an
authorized Saab dealer as soon as possible
to have the reason for low fluid level cor-
rected and original fluid installed.Automatic transmission Check the fluid level as follows:
1 Stand the car on level ground and apply
the parking brake. The automatic trans-
mission fluid must be at normal running
temperature, approximately 175°F
(80°C). This can be achieved by driving
the car for about 30 min on the open
road.
2 With the engine idling, move the selector
lever to D and wait for at least
15 seconds. Next, move the selector
lever to R and wait for 15 seconds again.
Finally, move the selector lever to P. Let
the engine idle.
3 Wipe the dipstick clean with a lint-free
cloth and put it back.
4 With the fluid at normal temperature, the
level should be between the MAX and
MIN marks on the dipstick. Top up, as
necessary, with Saab 3309 automatic
transmission fluid (mineral oil-based),
adding it through the dipstick pipe. The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 0.4 qts
(0.4 liter).
If the outside temperature is below 50°F
(10°C), the fluid will not reach the specified
temperature of 175°F (80°C). In this case,
the correct fluid level may be 0.8 in (20 mm)
below the MAX mark.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders.
 Avoid prolonged skin contact when-
ever possible. Wash the affected area
thoroughly with soap and water after
any contact.
 Keep oil out of reach of children.
 Do not touch the turbocharger or
manifold. These get very hot when the
engine has been running.
 Do not spill oil on hot parts of the
engine as this could cause a fire. Used
engine oil is particularly flammable.
 Protect the environment. Do not dis-
pose of oil in the ground or down a
drain. Dispose of all used oil and oil fil-
ters at an appropriate disposal facility.
NOTEIf there is a smell of burning fluid or the
fluid is black, change the fluid.
