140 Starting and drivingIgnition switchThe combined ignition switch and
gear-lever lock is located in the center con-
sole between the front seats. The ignition
key can only be removed when reverse is
engaged (automatic transmission: selector
in ”P” position).
The key fits all the locks on the car. The key
number is specified on the small plastic
strap that comes with the keys when the car
is delivered. Keep a note of the key number
in a safe place, as you will need to quote it if
ordering a replacement key.

142 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.
Note:
On cars with manual transmission, if the
starter fails to engage when the ignition key
is turned to the start position, make sure the
clutch pedal is full depressed. Misposi-
tioned floor mats or other obstructions
under the clutch pedal may affect starting.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 3
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. 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.
There is also the risk that exhaust
gases may enter the cabin.

143 Starting and driving
Useful tips on cold climate
startingIf 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.
Limp-home modeThe engine management system has a
diagnostic feature that continually checks a
number of internal functions.
If, for example, a fault is detected in the
throttle valve, the engine management
system will go into Limp-home mode.This
limits:
idling control,
disables the cruise-control system and
limits the capacity of the A/C compressor.
If the limp-home mode is in operation (”Ser-
vice Engine Light also known as CHECK
ENGINE” light on, see below) and the out-
side temperature is close to or below freez-
ing, you may need to use some throttle on
starting (some pressure on the accelerator).
If the diagnostic system has detected a fault
in the engine-management system, the
”Service Engine Light also known as
CHECK ENGINE” light on the main
instrument panel will come on (see page
58), indicating that you should have the car
checked as soon as possible by a work-
shop. We recommend that you contact an
authorized Saab dealer.
NOTICEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suit-
able place as soon as possible and turn
off the engine. The car must be towed to
a workshop. We recommend that you
contact an authorized Saab dealer.
If the CHECK ENGINE warning light
flashes, it indicates that the engine is mis-
firing which can result in damage to the
catalytic converter.

144 Starting and drivingImportant
considerations for
drivingThe engine-management system in the
Saab 9-5 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum driv-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
Refrain from using full throttle before
the engine has warmed up (before
needle in mid-range on temperature
gauge).
A safety function prevents the engine
from revving faster than 6,000 rpm by
limiting the induction air.
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
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is
perfectly normal; the extent will depend
on the grade of fuel in the tank.
Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
NOTICE If the engine sounds strange there is a
fault in the system. Have the car
checked without delay by a workshop.
We recommend that you contact an
authorized Saab dealer.
The use of fuel with too low an octane
rating can cause serious engine
damage.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, longer than
for a standard state emission inspection,
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 be obtained at
the corresponding road speed.

146 Starting and drivingRefueling
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.
NOTICE Do 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
damage.
Clean fuel from painted surfaces as
soon as possible.
Do not use additives with E85-fuel.
NOTICEThe engine control module (ECM) mon-
itoring the engine parameters also
stores fault codes.
Under certain circumstances, this may
cause constant illumination of the ”Ser-
vice Engine Light also known as CHECK
ENGINE” indicator light , thus indi-
cating a fault that must be checked by
your Saab dealer, see page 58.
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 3 clicks.
Avoid driving with the fuel low level
indicator illuminated. The symbol
illuminates when less than approxi-
mately 2 gallons (8 litres) of fuel
remains in the tank.

147 Starting and driving
Refueling1 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 3 clicks.
Make sure you fully install the cap.
The diagnostic system can determine if the
fuel cap has been left off or is improperly
installed. See Service Engine Light also
known as CHECK ENGINE indicator light
on page 58.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.
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
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.
NOTICEDo 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
different fuel stations and outside
temperature. 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.
When refueling, hang the fuel cap inside
the fuel door

148 Starting and drivingFilling 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.
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 knocking 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
considered 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. Although
not required, use higher octane fuel for opti-
mum performance - 93 octane.
Gasoline 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
smog-check test. See Service Engine Light
also known as CHECK ENGINE indicator
light on page 58. 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.
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.
NOTICEGasolines 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.

159 Starting and driving
Cruise controlFor safety reasons (brake system func-
tion) the brakes must be applied once,
when the engine has started, before the
cruise control system can be activated.
The system is operated by means of the
controls on the stalk switch:
ON/OFF (switch on/off).
RESUME/– (Resume preset speed).
SET/+ (to set the desired speed).
CANCEL (Cancel operation of system,
e.g. to reduce speed temporarily).
When the system is ON, the CRUISE indi-
cator light will appear on the main instru-
ment panel and will be extinguished when
the system is switched OFF. If CANCEL is
selected, CRUISE will flash once.
To set the desired speed Move the switch to ON. Accelerate to the
desired speed (minimum speed: 25 mph
(40 km/h))and press SET/+. To increase the preset speed Accelerate to the desired speed and press
SET/+.
You can also increase the speed of the car
using the SET/+ button. Press it once to
increase the speed by 1 mph (1.6 km/h) or
hold it in and release when the desired
speed is reached. Temporary increase in speed Press the accelerator to override the preset
speed, e.g. for overtaking. When you release the accelerator, the
system will revert to the preset speed.
To cancel temporarily Move the control stalk to CANCEL
(spring-loaded position before OFF posi-
tion). This will disengage the system but the
preset speed will be retained in the system
memory. (The memory is deleted when the
engine is switched off.) To re-engage the system To revert to the preset speed, slide the
switch to RESUME/–. This will only operate
when the car’s speed is above 25 mph
(40 km/h).
WARNING
Do not use the Cruise control system
on wet or icy roads, in dense traffic or
on winding roads.
Set the control to OFF when you do
not want to use the system, to prevent
the system being activated inadvert-
ently.
