212 Car care and technical informationMaxi fusesThe Maxi fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The Maxi fuses are designed to protect the
car’s electrical system from being dama-
ged. Each Maxi fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare Maxi fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules that monitor and control a variety
of functions, including:
DICE controls (among other things):
 Front lights and interior lighting
 Instrument illumination
 Intermittent wiper operation
 Electric heating of rear window and door
mirrors
 Cooling fans
TWICE controls (among other things):
 Central locking.
 Car alarm (Anti-theft system)
 Engine immobilizer
 Autochecking of lights.
 Electric heating of rear seat
 Safety belt reminder
 Electrically adjustable passenger seatThe DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control
modules and components connected to the
bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which facilitates fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTICEIf a Maxi fuse blows, it means that there is
a major fault in the electrical system.
Have the car checked without delay by an
authorized Saab dealer.

231 Car care and technical information
Changing a wheel
WARNING
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
flat tire. If it is used for anything else, you
or others could be badly injured or killed if
the vehicle slips off the jack. Use the jack
provided with your vehicle only for chang-
ing a flat tire.
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1 Set the parking brake firmly.
2 If you have an automatic transmis-
sion, put the shift lever in PARK (P).
For a manual transmission, leave the
car in gear (1st or REVERSE (R)).
3 Turn off the engine and do not restart
while the vehicle is raised.
4 Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle won't
move, you should put blocks at the front
and rear of the tire farthest away from the
one being changed. That would be the
tire, on the other side, at the opposite end
of the vehicle.
 The car jack is designed solely for use
in changing a wheel or fitting snow
chains.
It must not be used to
support the car during repair work
or servicing.
Never
crawl under a car that is
supported only by a jack.
 Raising your vehicle too high or with
the jack improperly positioned can
damage the vehicle and even make
the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to
fit the jack lift head into the proper
location before raising the vehicle, and
raise the vehicle only far enough off
the ground so there is enough room for
the spare tire to fit (no more than 25
mm or 1 inch clearance between the
ground and the bottom of the tire).
 Switch on the hazard warning lights if
the car is on a road.
 The jack should be stored correctly
under the carpeting in the trunk. If it
lies loose in the car, it could thrown
forward and cause personal injury in
the event of a crash or if the car rolls
over.
 Grit, salt and rust can clog the inner
threads of the wheel bolts if the car has
been driven for several years exclu-
sively with alloy wheels.
If steel wheels are being installed, the
bolt hole threads in the brake hubs
should be cleaned before the thinner
steel wheels are fitted. It may other-
wise not be possible to achieve the
correct clamping force, despite tight-
ening the wheel bolts to the correct
torque.

232 Car care and technical informationTo jack up the car, apply the jack to one of
the special jacking points under the sills.
If a floor jack is used, it can be applied to the
standard jacking points used by the dealer.
A floor jack can lift both front wheels or both
rear wheels off the ground simultaneously.
A jack stand must then be applied underne-
ath the front of the engine subframe (at the
fixing point for the towrope-attachment eye)
or to the rear towrope-attachment eye (or
under the trailer hitch, if fitted).1 Put the car in 1st gear (automatic trans-
mission: move selector to the P position)
and apply the parking brake.2 Wind the jack up to a suitable height
before placing it under the recess in the
sill.
Make sure that the jack fully engages
the recess in the sill and that the base of
the jack is steady and flat on the ground.
3 Remove the wheel cover (where appli-
cable).
Loosen the wheel bolts by half a turn.
4 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.
5 Clean any rust or dirt from the contact
surfaces between the wheel and brake
disc. Do not wipe away the grease in the
hub.
6 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs) - see
page 234.

235 Car care and technical information
Fault diagnosisIf a fault occurs in the A/C system, there are
a number of checks you can perform your-
self. If the fault persists, however, have the
system checked by an authorized Saab
dealer.Important!When the A/C system is running, the intake
air is dehumidified, and the resultant con-
densation is drained off through two outlets
underneath the floor of the car in the vicinity
of the front doors. It is therefore perfectly
normal for water to be seen dripping from
these outlets when the car is parked. The
warmer the ambient air and the higher the
humidity, the greater will be the amount of
condensation formed.Inadequate cooling:a Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
b Make sure that the drive belt for the com-
pressor is not slipping.
c Check the fuses for the ventilation fans
and compressor.
Maintenance The drive belt for the compressor should
be inspected under the regular service
program.
 Clean dirt and insects away from the con-
denser and radiator to prevent clogging.
When washing the car, use the hose to
spray the radiator and condenser (located
forward of the radiator) from both sides
(both from the front of the car and from
inside the engine bay). Do not use a pres-
sure washer.Caution: Do not use the hose when the
engine is hot.Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.Note:
The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F).
Safety beltsRegularly check the function of the safety
belts as follows:
 Hold the diagonal strap and pull it sharply.
The safety belt should
lock
and it should
not be possible to withdraw it further.
Check the anchorage points in the floor.
They must not have suffered rust damage.
There must be no frayed threads in the web-
bing.
Safety belts must not come into contact with
substances such as polishes, oils or other
chemicals. If the straps are dirty, wash them
with warm water and a detergent or have
them replaced.
WARNING
If the car is involved in a crash, the safety
belts, belt pretensioners and other
components must be inspected by an
authorized Saab dealer.
Never make any alterations or repairs to
the safety belt yourself.

238 Car care and technical informationWaxing and polishingOther than in exceptional cases, do not use
abrasive polishes containing a cutting agent
on a new car. Always wash the car tho-
roughly before waxing or polishing.Engine compartmentClean the engine compartment using an
engine detergent and rinse with hot water.
Cover the headlights. Do not use high-pres-
sure washer. Avoid spraying the hood liner,
as this can become heavy and hang down
and touch the engine when the hood is clo-
sed.
Do not use gasoline as a cleaning agent or
solvent when carrying out repairs or mainte-
nance. Saab recommends the use of envi-
ronmentally safe degreasing agents.
Touching up the paintDamaged paintwork should be treated as
soon as it is discovered: the longer it is left,
the greater the risk of corrosion. The anti-
perforation warranty does not cover corro-
sion resulting from untreated defects.
Paintwork damage sustained in a crash is
usually extensive and can only be properly
restored by professionals.
However, you can repair small scratches
and stone-chip damage yourself. The
necessary tools and materials, such as pri-
mer, touch-up paint and brushes, are avai-
lable from your Saab dealer.
In the case of minor flaws in the paintwork,
where the metal has not been exposed and
an undamaged layer of paint remains,
touch-up paint can usually be applied
directly, after any dirt has been scraped
away using a pointed knife.If corrosion has already set in, e.g. as a
result of stone-chip damage, use a pointed
knife to scrape off all surface rust. If pos-
sible, the damaged area should be taken
back to the bare metal. The metal should
then be primed with two thin coats of primer
applied by brush.
After the primer has dried, apply several thin
layers of topcoat enamel until the surface of
the repaired area is flush with the surroun-
ding paintwork.
Stir both primer and touch-up enamel tho-
roughly before use and allow each coat to
dry before applying the next.

241 Car care and technical information
2Clean the underside of the car during
the winter.
Use high pressure water to
clean the car’s underside (floor panels,
wheel wells) at least at mid- winter and
in the spring.
3
Inspect the car frequently for leaks or
damage, and arrange for needed
repairs promptly.
After washing or after
heavy rain, check for leaks. When wash-
ing the car inspect body surfaces for
paint damage. While checking for leaks,
lift the floor mats and check beneath
them. Water can collect in these areas
and remain for prolonged periods. Dry
any wet areas including the floor mats.
Have leaks repaired as soon as pos-
sible.
Use touch-up paint to repair small scrat-
ches or minor finish damage. Areas
where metal is exposed will rust quickly
and MUST be repaired immediately by
touch-up or professional repainting.
Rust must be removed, the bare metal
primed and painted. Major body
damage should be repaired immediately
and new panels or exposed areas
should be undercoated with anti- corro-
sion material.
Repairs of this type are the owner’s
responsibility and are not covered under
warranty.4
Inspect the undercoating and touch
up if necessary.
Pay particular atten-
tion to the fenders and wheel housings,
which are exposed to abrasion by flying
gravel, etc. If the composition has worn
or flaked off, the steel must be tho-
roughly cleaned and dried before a fresh
coat is applied. The cleaning is best
done with a scraper and a steel wire
brush, followed by washing with solvent.
Apply the new coating thinly, as other-
wise it may run off or fall off when dry.
For long tripsBefore setting off on a long journey, it is
advisable to have your car checked over by
your Saab dealer.
Obtain a few important items to take along
on your journey such as spare bulbs, wiper
blades, fuses, a Poly-V-belt and the like.
You can check some points yourself befor-
ehand:
 Make sure that the engine is in good con-
dition.
 Check that no oil or gasoline leaks out of
the engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the Poly-V-belt and replace it if it
shows any signs of hard wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
the jack in the car.
