53 Instruments and controls
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 186).
This light will come on together with if
the battery is discharging. If it comes on
while you are driving, stop the car as soon
as possible and switch off the engine.
Check the alternator drive belt (see
page 194). If the belt has broken, the engine
may overheat (cooling system will not func-
tion properly), the battery will not be char-
ged, the A/C compressor will not run and
power assistance for the steering will be
lost.This light will come on together with if
there is insufficient brake fluid in the reser-
voir (see pages 189).
If the ABS warning light is on at the same
time, the ABS system may be inoperative
because of a fault (see ”Anti-lock brake war-
ning”, page 54).
Warning, oil pressure

58 Instruments and controlsAutochecking of lights,
main instrument panel The above warning and indicator lights
should come on when the ignition is swit-
ched on prior to starting. They should go out
after about 3 seconds.
The following lights light up until the engine
is started, presuming that no fault exists:
 Central warning light .
 Oil pressure warning light .
 Warning, charging .
InstrumentsTachometerThe tachometer indicates the engine speed
in thousands of revolutions per minute. The
needle may be allowed to enter the broken
red zone on the dial only for an instant.
A safety cut-out function (in the fuel system)
prevents the engine speed from exceeding
approximately 6,000 rpm.
Odometer and trip meter The odometer records the distance traveled
in miles on U.S. vehicles and on Canadian
vehicles the distance indicated is in kilome-
tres, and the trip meter in miles and tenths
(kilometres and tenths of kilometres on
Canadian vehicles). Reset button The reset button has two functions, determi-
ned by whether the ignition is ON or OFF.
 When the ignition is ON, pressing the
button will reset the trip meter.
 When the ignition is OFF, the display
lights up for 20 seconds enabling you to
read the odometer and trip meter. Pres-
sing the button a second time within these
20 seconds will reset the trip meter.

AdditivesTo provide cleaner air, all gasolines in the
United States are now required to contain
additives that will help prevent engine and
fuel system deposits from forming, allowing
your emission control system to work prop-
erly. You should not have to add anything to
your fuel. However, some gasolines contain
only the minimum amount of additive
required to meet U.S. Environmental Pro-
tection Agency regulations. Saab recom-
mends that you buy gasolines that are
advertised to help keep fuel injectors and
intake valves clean. If your vehicle experi-
ences problems due to dirty injectors or
valves, try a different brand of gasoline.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gaso-
lines may be available in your area to con-
tribute to clean air. Saab recommends that
you use these gasolines, particularly if they
comply with the specifications described
earlier.
Notice: Your vehicle was not designed
for fuel that contains methanol. Do not
use fuel containing methanol. It can cor-
rode metal parts in your fuel system and
also damage the plastic and rubber
parts. That damage would not be cove-
red under your warranty.Some gasolines that are not reformulated
for low emissions may contain an octane-
enhancing additive called methylcyclopen-
tadienyl manganese tricarbonyl (MMT); ask
the attendant where you buy gasoline
whether the fuel contains MMT. Saab does
not recommend the use of such gasolines.
Fuels containing MMT can reduce the life of
spark plugs and the performance of the
emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your authorized Saab
dealer for service.
Fuels in Foreign CountriesIf you plan on driving in another country out-
side the United States or Canada, the
proper fuel may be hard to find. Never use
leaded gasoline or any other fuel not recom-
mended in the previous text on fuel. Costly
repairs caused by use of improper fuel
would not be covered by your warranty.
To check the fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you will
be driving.

146 Starting and drivingIf ”Automatic transmission, fault indicator”
light appears on the main instrument panel,
the system has detected a fault in the auto-
matic transmission or its control module
(see page 57).
This also means that the Limp-home mode
has been selected, to guard against further
damage being done to the transmission. In
this mode, the automatic transmission
starts in 5th gear, and gear changes (if nec-
essary) will have to be made manually.
Stop the car in a safe place. Switch off then
restart the engine. If the fault is intermittent,
the transmission will operate as normal
despite the fault indicator being on. Have
the car checked at an authorized Saab
dealer.
It is not possible to select the SPORT or
Sentronic mode when the Limp-home mode
is active.
Gear changes must be made manually.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in Limp-home mode:
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”Gearbox too hot.
Make a safe stop.”
In this event, stop the car in a suitable place,
switch off the engine and open the hood.
Wait for several minutes then turn on the
ignition to check that the message has gone
out. When driving subsequent to the trans-
mission fluid overheating, select a gear in
which the engine speed is 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. High ambient temperatures can
also increase the temperature of the trans-
mission fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 161).

Position R D M L
Gear Reverse 5th 5th 2nd
NOTICEIf 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.
Select position L to prevent unnecessary
wear on the transmission. The transmis-
sion then starts in 2nd gear. Once the car
is moving you can select position D.
When the indicator light is on, the car
must not be driven with a caravan or trai-
ler attached.

4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to a major metal
engine part with a good ground. Do not
connect (+) to (–) or you will get a short
that could injure you or would damage
the battery and maybe other parts as
well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.
7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the black negative (–)
cable to the good battery’s negative
terminal.NOTICEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water.
The battery installed in your new Saab
has filler caps. Be sure the right amount
of water is there. Add distilled or boiled
water if the level is too low. If you don’t,
explosive gas could be present.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.

186 Car care and technical informationEngineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cams-
hafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration to a minimum.
The balance shafts are chain driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the coun-
ter-rotating shafts counteract the vibration
from the moving parts of the engine.
The transmission, located on the right (vie-
wed from the front), is integrated with the
engine. All models have front-wheel drive.
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 stan-
ding on level ground. Remove the dipstick
and wipe it clean before checking the level.
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 recommen-
ded grade via the dipstick tube.

187 Car care and technical information
Changing engine oil
The engine oil must be changed in accor-
dance with the service program, see
page 246.
Oil volume and grade, see page 255.
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.
Change of engine oil and oil filter may be
required more frequently, see page 246.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders. Avoid prolonged
skin contact whenever possible.
 Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin by
washing thoroughly with soap and
water.
 Keep oil out of reach of children.
 Do not touch the turbocharger or
exhaust 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
dispose of oil in the ground or down a
drain. Dispose of all used oil and oil
filters at an appropriate disposal facil-
ity.
