93 Instruments and controls
You can check the distance left by selecting
Dist. At the same time you can check the
calculated time of arrival.
After the distance to destination has
decreased to zero, Dist will function as a trip
meter (see Using DIST as a trip meter). The
starting value for the trip meter will be the
last distance set for the Dist function.
Example: The Dist function is set to
100 miles. After the count-down has
reached 0 miles, Dist will act as a trip meter
beginning at 100 miles.Calculating the arrival time if a specified
average speed is maintained
(When will I arrive if I know how far I have to
drive and know what my average speed will
be?)
This function should be used before starting
out a journey.
First, set the distance under Dist.
1 Then select SpeedØ function.
2 Press and hold the SET button until
given audible confirmation.
3 Set the estimated average speed using
the steering wheel controls.
4 Confirm the setting by pressing the SET
button.
The distance and the calculated time of
arrival is now displayed.
The time of arrival is updated during the
journey based on the average speed since
Dist was set. The speed of the car must
exceed 12 mph (20 km/h).
By selecting Dist during the journey, you
can see how much distance is left to travel.
When Dist reaches zero it acts as a trip
meter. The trip meter starts from the dis-
tance that was set previously.
NIGHTPANELTo 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 NIGHTPANEL button is pressed,
only the speedometer will be illuminated.
All other instrument lighting will be switched
off and the needles drop to zero.
Note: All indicator and warning lights and
messages will operate normally if required.
Temp (when the outside temperature falls
or rises to between 26 and 38°F (–3 and
+3°C)) and D.T.E. (when the remaining fuel
is only sufficient for approx. 80 miles
(50 km) of driving) are even shown in Night
Panel model.

155 Starting and driving
Starting the engineAvoid racing the engine or loading it heavily
before it has warmed up. Do not drive away
before the warning and indicator lights have
gone out.
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 Make sure the parking brake is applied.
2 Depress the clutch pedal but do not
touch the accelerator.
3 Start the engine. Let the ignition switch
spring back as soon as the engine has
started and is running smoothly.
Allow the engine to idle for about
10 seconds. Do not apply full throttle for at
least 3 minutes after starting.Cars with automatic transmission
The selector lever must be in the P or N
position.
1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
Note! Once the engine has started, the
brake pedal will sink. This is perfectly
normal.
3 Start the engine. Let the ignition switch
spring back as soon as the engine has
started and is running smoothly.
Allow the engine to idle for about
10 seconds. Do not apply full throttle for at
least 3 minutes after starting.
Useful tips on starting the engineIf the engine has failed to start after several
attempts in very cold weather, proceed as
follows:
1 Turn the ignition switch to ON (it is
essential that you turn the ignition to
ON before depressing the accelerator).
2 Press the accelerator to the floor and run
the starter motor for 5-10 seconds. This
will prevent the engine being flooded
(fully depressed accelerator cuts off the
fuel supply).
3 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.

156 Starting and drivingImportant
considerations for
driving1 Starting and driving
Do not use full throttle until the engine
is warm, so as to avoid unnecessary
wear. If the needle of the turbo gauge
repeatedly enters the red zone, the
engine may suddenly lose power, due
to the initiation of a monitoring system
that limits the boost pressure. We
recommend that you contact a Saab
dealer as soon as possible.
Under certain barometric conditions
(high outside temperature and/or high
altitude) the needle may enter the first
part of the red zone without necessarily
indicating that a fault has arisen.
A protective function (interruption of the
fuel supply) limits the engine speed.2 Stopping the engine
Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the boost pressure
One of the advantages of boost pres-
sure regulation is that the engine can
also be run safely on gasoline with a
lower octane rating, although not lower
than AON 87. However, engine perfor-
mance will fall slightly and heavy load-
ing and laboring should be avoided. For
optimum performance, use the recom-
mended grade of fuel.
The maximum boost pressure is regu-
lated according to the tendency of the
engine to knock. Short-lived knocking
is perfectly normal. This can occur
when the engine is running at about
3,000 rpm under a heavy load. The
extent of this knocking will depend on
the grade of fuel in the tank.
Isolated instances of knocking can
occur with low-octane fuel. This
controlled form of knocking, followed by
a reduction in the boost pressure, is a
sign that the control system is working
normally, and is perfectly safe for the
engine.The light comes on in the event of an engine
or gearbox fault (cars with automatic gear-
box), which may cause drivability problems
but that does not affect exhaust emission.
The car can still be driven but perhaps with
limited performance.
Contact a dealer whenever an opportunity
occurs. We recommend that you contact a
Saab dealer.
NOTEIf the engine sounds strange there is a
malfunction. We recommend that you
contact a Saab dealer immediately.
The use of fuel with too low an octane
rating can cause serious engine dam-
age.
Limited performance.

157 Starting and driving
Limp-homeThe engine management system has a
diagnostic feature that checks a number of
internal functions. If a fault is detected in the
throttle valve, the engine management
system will set the throttle system to the
limp-home mode. This means:
idling control will be poor (uneven idling
since regulated by ignition and fuel
supply)
engine performance will be reduced
the cruise control will not function
the capacity of the A/C compressor will be
limited.
If the diagnosis function detects a fault in the
engine management system, the light
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see
page 83). Have the car checked at a work-
shop as soon as possible. We recommend
that you contact a Saab dealer.
Important considerations with
catalytic convertersThe catalytic converter is an emission con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (precious
metal alloy).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
NOTEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter can be damaged),
ease off the accelerator slightly. The light
should go out or start to shine constantly.
If the light continues to flash despite
easing off the accelerator, you may con-
tinue to drive the car but at the minimum
throttle permitted by the current traffic sit-
uation. Have the car checked as soon as
possible. We recommend that you con-
tact a Saab dealer.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

158 Starting and drivingHave the car serviced regularly in accor-
dance with the service program.
Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a workshop. We
recommend that you contact a Saab
dealer.
If the engine fails to start (in severe cold or
if the battery is flat), the car can be bump
started (manual transmission only) or
started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter. We
recommend that you contact a Saab
dealer for advice.Never park the car on dry grass or other
combustible material. The catalytic
converter gets very hot and could there-
fore start a fire.
Never drive off if the engine is misfiring.
If you bump start the car when the engine
is already at normal working temperature,
the engine must start to run on all cylin-
ders. Abort bump starting if the engine
fails to start immediately.
Failure to strictly follow these instructions
can result in damage to the catalytic con-
verter and associated components, and
could represent a breach of the warranty
conditions.
NOTEIf the car runs out of gas, air may be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would obtain at the corre-
sponding road speed.

Refueling
WARNING
If you spill fuel and then something ignites
it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap
too quickly. This spray can happen if your
tank is nearly full, and is more likely in hot
weather. Open the fuel cap slowly and
wait for any “hiss” noise to stop. Then
unscrew the cap all the way.
Gasoline fumes are highly explosive.
Therefore:
never smoke while refueling.
never use gasoline for any purpose
other than as engine fuel.
gasoline is extremely flammable and
can cause severe burns. No open or
exposed flames near gasoline.
do not use a mobile phone at the
same time as refueling.
If a fire starts while you are refueling, do
not remove the nozzle. Shut off the flow of
fuel by shutting off the pump or by notify-
ing the station attendant. Leave the area
immediately.
NOTEDo not overfill. Fuel should not come
right up the filler pipe as room for
expansion is needed for when the
temperature rises.
The use of fuel with too low an octane
rating can cause serious engine dam-
age.
Clean fuel from painted surfaces as
soon as possible.
NOTEThe engine control module (ECM) moni-
toring the engine parameters also stores
fault codes.
Under certain circumstances, this may
cause constant illumination of the Engine
malfunction (CHECK ENGINE) lamp
, thus indicating a fault that must be
checked by your Saab dealer, see
page 83.
NOTE: always observe the following two
measures:
Make sure that the fuel filler cap is
screwed on correctly before the
engine is started. Screw on the fuel
filler cap until you hear three clicks.
Avoid driving with the fuel low level
indicator illuminated. The symbol illu-
minates when less than approximately
2.5 gallons (10 litres) of fuel remains
in the tank.

160 Starting and drivingRefueling1 Switch off the engine.
2 Open the fuel cap, located in the
right-hand rear fender.
3 Insert the fuel pump nozzle beyond the
flange on the filler pipe and let the first
mark (a ring, a pimple or the first
spring-coil) rest on the flange. Do not
withdraw the nozzle while filling is in
progress.
4 Cease refueling the first time the pump
stops, and wait a few seconds after
you’ve finished pumping before you
remove the nozzle.Fuel cap
To remove the fuel cap, turn it slowly to the
left (counterclockwise). The fuel cap has a
spring in it; if you let go of the cap too soon,
it will spring back to the right.
When you put the fuel cap back on, turn it to
the right (clockwise) until you hear three
clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the
fuel cap has been left off or is improperly
installed. See Engine malfunction (CHECK
ENGINE) on page 83.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank full.
WARNING
If a fire starts while you are refueling, do
not remove the nozzle. Shut off the flow of
fuel by shutting off the pump or by notify-
ing the station attendant. Leave the area
immediately.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed when the temperature rises.
Fill to maximum filling capacity.
Stop filling after the first time that the
nozzle trips to shut off the flow of fuel.
Filling capacity can differ between dif-
ferent fuel stations and outside tem-
perature. Fuel tank volume when
nozzle trips to shut off, may vary by
0.5 gal. (2 liters).
Do not fill fuel all the way up the filler
pipe. The gasoline must be allowed
room for expansion especially during
hot weather.

161 Starting and driving
Refer to page 187 for information regarding
gasoline anti-freeze.
The fuel door has a built in filler cap holder
slot located on the fuel door. Slide the white
ring on the cap into the slot.
Notice: If you need a new fuel cap, be sure
to get the right type. Your dealer can get one
for you. If you get the wrong type, it may not
fit properly.
Filling a portable fuel container Fuel (Gasoline Engine)
Fuel
Use of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.
For optimum performance Saab recom-
mends:
Gasoline engines – AON 90.
Gasoline Octane
Use regular unleaded gasoline with a
posted octane of 87 or higher. If the octane
is less than 87, you may get a heavy knock-
ing noise when you drive. If this occurs, use
a gasoline rated at 87 octane or higher as
soon as possible. Otherwise, you might
damage your engine. A little pinging noise
when you accelerate or drive uphill is con-
sidered normal. This does not indicate a
problem exists or that a higher-octane fuel
is necessary. If you are using 87 octane or
higher-octane fuel and hear heavy knock-
ing, your engine needs service.
WARNING
Never fill a portable fuel container while it
is in your vehicle. Static electricity dis-
charge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside
a vehicle, in a vehicle’s trunk, pickup
bed or on any surface other than the
ground.
Bring the fill nozzle in contact with the
inside of the fill opening before operat-
ing the nozzle. Contact should be
maintained until the filling is complete.
Do not smoke while pumping gaso-
line.
When refueling, hang the fuel cap inside
the fuel door93_US_M08.book Page 161 Friday, May 11, 2007 11:37 AM

162 Starting and drivingGasoline Specifications
It is recommended that gasoline meet spec-
ifications which were developed by automo-
bile manufacturers around the world and
contained in the World-Wide Fuel Charter
which is available from the Alliance of Auto-
mobile Manufacturers at www.autoalli-
ance.org/fuel_charter.htm. Gasoline meet-
ing these specifications could provide
improved driveability and emission control
system performance compared to other
gasoline.California Fuel
If your vehicle is certified to meet California
Emission Standards (see the underhood
emission control label), it is designed to
operate on fuels that meet California speci-
fications. If this fuel is not available in states
adopting California emissions standards,
your vehicle will operate satisfactorily on
fuels meeting federal specifications, but
emission control system performance may
be affected. The malfunction indicator lamp
may turn on and your vehicle may fail a
emission system inspection. See Engine
malfunction (CHECK ENGINE) on page 83.
If this occurs, return to your authorized Saab
dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel
used, repairs may not be covered by your
warranty.Additives
To 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 cov-
ered under your warranty.
Some gasolines that are not reformulated
for low emissions may contain an
octane-enhancing additive called methylcy-
clopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy NOTEGasolines containing oxygenates, such
as ethers and ethanol, and reformulated
gasolines may be available in your area.
We recommend that you use these gaso-
lines, if they comply with the specifica-
tions described earlier. However, E85
(85% ethanol) and other fuels containing
more than 10% ethanol must not be used
in vehicles that were not designed for
those fuels.93_US_M08.book Page 162 Friday, May 11, 2007 11:37 AM
