is shown on the SID, after a failed start
attempt, the cause could be a fault in the
transmitter in the key, or in the receiver in
the ignition lock. The following should be
done:
Turn the key back to the LOCK position.
Turn the key to ON.
Press one of the buttons on the remote
control (the LED stops blinking).
Start the engine.
Try another key. If this works, then the fault
is in the first key.
We recommend that you contact an autho-
rized Saab dealer for checking and rectifica-
tion.
Note:
Certain electronic items, such as cellular
phones, may affect the starting produce-
dure. Be sure that all devices are clear of the
key/ignition switch area.
Starting the engine
NOTICETake care not to spill drinks or to drop
crumbs over the ignition switch. If dirt or
liquid gets into it, the switch may not
operate properly.
WARNING
Always remove the key before leaving
the car.
Always apply the parking brake before
removing the ignition key.
WARNING
When starting the engine:
– Sit down in the driver’s seat.
– Depress the clutch pedal fully. If the
gear lever is not in the neutral position,
the clutch pedal must be fully depres-
sed or the car will jump forwards or
backwards, which may cause a crash.
– Never start the car from outside the
vehicle, e.g. through a wound down
window. This could lead to serious
personal injury.
Engage reverse (R) (position P for
automatic transmission) to remove the
ignition key. The key can only be
removed in this gear position.
Carbon monoxide (CO) is a colorless,
odorless, poisonous gas. Be alert to
the danger of CO – always open the
garage doors before starting the
engine in the garage.
There is also a danger of CO poison-
ing if the exhaust system is leaking.

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
(”Engine malfunction (CHECK ENGINE)”
light on, see below) and the outside temper-
ature is close to or below freezing, 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
”Engine malfunction (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 workshop. 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 per-
fectly 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.

145 Starting and driving
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 (mixture of
precious metals).
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:
Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
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 as soon as
possible. We recommend that you con-
tact an authorized Saab dealer. If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be push started (manual gearbox only) or
started using jumper cables 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 five minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with a
workshop for advice. We recommend that
you contact an authorized Saab dealer. Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
start a fire.
Never drive off if the engine is misfiring.
If you jump start the car when the engine
is already up to normal temperature, the
engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
Failure to follow these directions could
result in the catalytic converter and associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
NOTICEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.
NOTICEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.

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.
NOTICEThe engine control module (ECM) mon-
itoring 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 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 distinct
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
Refueling
1 Switch off the engine.
2 Open the filler 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.Filler cap
When you put the filler cap back on, turn it
to the right (clockwise) until you hear three
clicks. Make sure you fully install the cap.
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.
NOTICE 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 filler 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.
For optimum performance Saab recom-
mends:

Gasoline Octane
Use premium unleaded gasoline with a
posted octane of 93 or higher for best per-
formance. You may also use regular
unleaded gasoline rated at 87 octane or
higher, but your vehicle's acceleration may
be slightly reduced.
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.
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 Engine malfunction
(CHECK ENGINE) on page 58. If this
occurs, return to your authorized Saab
dealer for diagnosis. If it is determined that
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.

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
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 Countries
If 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.95_U S _M 07.book Page 149 Friday, June 9, 2006 8:58 AM

150 Starting and drivingEngine Break-In PeriodPistons, bores and bearings need time to
obtain uniform, wear-resistant surfaces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km), do
not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km).
Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible during
this period.
Gear changingManual transmissionTo start the engine the clutch pedal must
be fully depressed.
The gear positions are marked on the gear
lever. Before reverse (R) can be engaged,
you must lift the ring underneath the
gear-lever knob.
To change gear, fully depress the clutch
pedal and then release it smoothly. It is
inadvisable to drive with your hand resting
on the gear lever, as this can increase the
wear on the transmission.
When changing down from 5th to 4th gear,
ease the gear lever straight back, without
applying any lateral pressure. This will pre-
vent 2nd gear being engaged by mistake,
which can result in overreving and possible
damage to the engine.
Before engaging reverse, wait till the car is
at a standstill, release the accelerator and
fully depress the clutch. From neutral, press
the gear lever firmly to the right before
easing it back into reverse.
