57 Instruments and controls
CHECK message indicator
This light indicates that there is a message
in the Saab Information Display (SID). A
chime will also sound
(see page 67).
Central warning light
This light will come on and a chime will
sound if a fault has been detected in any
system that is critical to safety. Any of the
following can activate the central warning
light and alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Electronic brake force distribution (distri-
bution of brake pressure between front
and rear wheels).
 Engine overheating.
 Alternator not charging properly.
Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance (see page
151).
Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
WARNING
An illuminated ”Engine malfunction
(CHECK ENGINE)” indicator light indi-
cates an engine-related problem. While
your car may be able to be driven with the
”Engine malfunction (CHECK ENGINE)”
indicator light illuminated (Limp-home
mode), you are advised to have your car
serviced at an authorized Saab dealer as
soon as possible.
Continued driving without this problem
being corrected might cause serious
further damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g.brake
smoothly, engage neutral, stop in a suita-
ble place, switch off the engine, etc.).
NOTICEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.NOTICEIf the car runs out of fuel, air can be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.

67 Instruments and controls
CHECK messages When the engine is started, CHECKING will
appear on the display for about four sec-
onds, while the SID checks are being per-
formed.
When a CHECK message is generated
while the car is being driven, a chime will
sound, INFO DISPL will illuminate on the
main instrument panel, and the message
will appear on the SID. The number of mes-
sages that can be displayed by the SID
varies with the specification of the car.
If more than one CHECK message has
been generated, the
+ symbol will appear to
the left of the text on the display. The mes-
sages appear in order of priority.
If a new fault occurs while another message
is being displayed, the message relating to
the new one will appear for 10 seconds,
after which the display will return to the ear-
lier one.
Press CLEAR once to acknowledge a mes-
sage, whereupon it will be cleared from the
display. It will not be displayed again before
the ignition has been switched off and then
on again. The following messages may be displayed:
1 This message will be displayed approximately
600 miles (1,000 km) before the next sched-
uled service is due, or when 365 days have
elapsed since the last service. The message
should be cleared at the time of that service
(see the Saab Warranties & Service Record
Booklet).
This message can also be deleted by first
briefly pressing the CLEAR button, then
depressing it a second time for at least eight
seconds until ”SERVICE” appears on the dis-
play and a chime sounds. The message can
only be deleted when it is shown on the SID.
Night panelTo 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 Night Panel button is pressed,
only the speedometer will be illuminated (up
to the 87-mph or 140-km/h graduation), all
the other instruments illumination being
extinguished and their needles moved to
zero. Both the SID and the ACC displays will
be extinguished and the backlighting for
switches and other controls will be dimmed.
Note: All indicator and warning lights,
together with the display of CHECK mes-
sages, will operate as normal, except ”Out-
door temperature (Frost warning)”, see
page 64. Message See

Recommended fuel:The engine in your Saab 9-5 is designed to
operate on unleaded gasoline that has an
octane rating of 87 or higher. Octane rating
is determined according to the formula:
where MON is the Motor Octane Number,
and RON is the Research Octane Number.
The average of these two values is the
octane rating of the gasoline as it appears
on the pump at a retail gas station. This
value is sometimes referred to as the
"Anti-Knock Index" (AKI) or the "Average
Octane Number" (AON).
To avoid deposit formation on the fuel injec-
tors which can cause poor driveability, use
only quality gasolines that contain deter-
gents and corrosion inhibitors. Because
gasolines sold at retail gas stations vary in
their composition and quality, you should
switch to a different brand if you begin expe-
riencing driveability and/or hard starting
problems shortly after refueling your car. In
recent years, a variety of fuel additives and
alcohols or oxygenates have been blended
with gasoline. These types of gasolines may
be found in all parts of the United States and
Canada, but particularly in geographic
areas and cities that have high carbon mon-
oxide levels. Saab approves the use of such
"reformulated" gasolines in its products,
which help in reducing pollution from all
motor vehicles, provided that the following blending percentages are met by such
fuels:
 Up to 10 % ethanol by volume, with corro-
sion inhibitors.
 Up to 15 % MTBE by volume (methyl ter-
tiary butyl ether).
 Up to 5 % methanol by volume, with an
equal amount of a suitable co-solvent and
added corrosion inhibitors.
Other, less common, fuel additives used by
some gasoline dealers are also acceptable,
provided that the resultant gasoline is not
more than 2.7 % oxygen by weight.
Some Canadian and U.S. gasolines contain
an octane enhancing additive called meth-
lycyclopentadienyl manganese tricarbonyl
(MMT). If such fuel is used, your emission
control system performance may deterio-
rate and the malfunction indicator lamp on
your instrument panel may turn on. If this
occurs, return to your authorized Saab
dealer for service.
However, these blended gasolines are reg-
ulated and should never exceed these rec-
ommended blend percentages and service
station operators should know if their gaso-
lines contain detergents and oxygenates,
and have been reformulated to reduce vehi-
cle emissions. Nevertheless, if you begin to
notice a problem with the way your car starts
or runs shortly after it has been refueled, try
a different brand of gasoline.
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.

156 Starting and driving
Fuel (Gasoline Engine)Use regular unleaded gasoline rated at 87
octane or higher. Use of gasoline with an
octane rating lower than 87 can result in
severe engine damage. Damage caused by
incorrect fuel being used is not covered
under the terms of the New Car Warranty
and will be the responsibility of the owner. It
is recommended that the gasoline meet
specifications which were developed by the
American Automobile Manufacturers Asso-
ciation (AAMA) and endorsed by the Cana-
dian Motor Vehicle Manufacturers Associa-
tion for better vehicle performance and
engine protection. Gasolines meeting the
AAMA specification could provide improved
driveability and emission control system
performance compared to other gasolines.
Be sure the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If it’s
bad enough, it can damage your engine. If
you’re using fuel rated at 87 octane or
higher and you hear heavy knocking, your
engine needs service. But don’t worry if you
hear a little pinging noise when you’re accel-
erating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane
fuel to get rid of pinging. It’s the heavy, con-
stant knock that means you have a problem.
NOTICEHigher concentrations of methanol than
listed above, or the use of methanol-
blended gasoline without suitable
co-solvents and corrosion inhibitors,
can damage your car’s fuel system,
leading to the need for repairs which are
not covered by Saab’s product warranty.
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 57.
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.
In Canada, look for the
”Auto Makers’ Choice” label
on the fuel pump.

157 Starting and driving
If your vehicle is certified to meet California
Emission Standards (indicated on the
underhood emission control label), it is
designed to operate on fuels that meet Cali-
fornia specifications. If such fuels are not
available in states adopting California emis-
sions standards, your vehicle will operate
satisfactorily on fuels meeting federal spec-
ifications, but emission control system per-
formance may be affected. The ”Engine
malfunction (CHECK ENGINE)” indicator
on your main instrument panel may turn on
and/or your vehicle may fail a smog-check
test. See ”Engine malfunction (CHECK
ENGINE)” indicator on page 57. If this
occurs, return to your authorized Saab
dealer for diagnosis to determine the cause
of failure. In the event it is determined that
the cause of the condition is the type of fuels
used, repairs may not be covered by your
warranty. Some gasolines that are not reformulated
for low emissions may contain an
octane-enhancing additive called methylcy-
clopentadienyl manganese tricarbonyl
(MMT); ask your service station operator
whether or not the fuel contains MMT. Saab
Automobile AB does not recommend the
use of such gasolines. If fuels containing
MMT are used, spark plug life may be
reduced and your emission control system
performance may be affected. The malfunc-
tion indicator lamp on your instrument panel
may turn on. If this occurs, return to your
authorized Saab dealer for service.
Engine 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.

162 Starting and driving
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 178).
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. To avoid
the transmission 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 178). Towing Towing of cars with automatic transmission,
see page 188.
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
trailer attached.
WARNING
Remember to use engine-braking (selec-
tor position D or L) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

208 Car care and technical informationBrake and clutch fluid Checking the fluid level The combined brake and clutch-fluid reser-
voir is transparent to facilitate checking of
the fluid level.
The level should be between the MAX and
MIN marks. Top up, as necessary, with
DOT 4 fluid. Do
not
use DOT 5 brake fluid.
Use only new brake fluid from a sealed con-
tainer.
Check that there are no leaks in the brake
system.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.
Changing of the brake fluid should be
carried out by an authorized Saab dealer.The vehicle´s regular braking system is
adjusted automatically, but the parking
brake has to be adjusted manually. This
work, involving adjustment of the parking
brake cables and brake pads, must only be
carried out by an authorized Saab dealer.
It is not possible to detect, through abnormal
pedal or parking brake-lever travel, whether
brake pads are worn and need replacing. It
is therefore essential that brake pads be
checked regularly, as specified in the ser-
vice program.
Brake pad wear indicators The outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 0.11 in (3 mm),
the pad will produce a screeching, squeal-
ing or scraping noise when the brakes are
applied. New pads should be fitted without
delay.
Brake pads should only be changed by
an authorized Saab dealer. To ensure
optimum brake performance, use only
Saab original brake pads.
WARNING
Brake fluid deteriorates as it becomes
old. Because it is hygroscopic, it absorbs
water from the air and, in time, could allow
vapor to form in the brake system, thus
reducing its performance. It is therefore
important that brake fluid be changed reg-
ularly, as specified in the service pro-
gram.
NOTICEAvoid spilling brake fluid onto paintwork,
since it can cause the paint to bubble and
lift. If any brake fluid is spilled, the area
should be flushed with large quantities of
water as quickly as possible.

235 Car care and technical information
When It Is Time for New TiresOne way to tell when it’s time for new tires is
to check the treadwear indicators, which will
appear when your tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
You need a new tire if any of the following
statements are true:
 You can see the indicators at three or
more places around the tire.
 You can see cord or fabric showing
through the tire’s rubber.
 The tread or sidewall is cracked, cut or
snagged deep enough to show cord or
fabric.
 The tire has a bump, bulge or split.
 The tire has a puncture, cut or other
damage that can’t be repaired well
because of the size or location of the dam-
age.
Treadwear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
2/32" (1.6 mm) of tread remains. As soon as
the indicators become visible, new tires
should be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter (snow) tires.
Buying New TiresTo find out what kind and size of tires you
need, look at the Tire-Loading Information
label.
The tires installed on your vehicle when it
was new had a Tire Performance Criteria
Specification (TPC Spec) number on each
tire’s sidewall. When you get new tires, get
ones with that same TPC Spec number.
That way your vehicle will continue to have
tires that are designed to give proper endur-
ance, handling, speed rating, traction, ride
and other things during normal service on
your vehicle. If your tires have an all-season
tread design, the TPC number will be fol-
lowed by an “MS” (for mud and snow).
If you ever replace your tires with those not
having a TPC Spec number, make sure they
are the same size, load range, speed rating
and construction type (bias, bias-belted or
radial) as your original tires.
If you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities
available.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car’s directional stability, steering and brak-
ing in both wet and dry conditions.
