200 Car care and technical informationCharging/replacing the battery Connect the positive lead to the positive (+)
battery terminal (red), and the negative lead
to a good ground point, e.g. the lifting lug at
the front of the engine.
To remove the battery, always disconnect
the negative (black) lead first and reconnect
it last when fitting the new battery.
The battery size must comply with DIN
53735 MFI 230/2.16.

NOTICETo avert the danger of short-circuiting
between the positive (+) terminal on the
battery and the inlet manifold on the
engine, always disconnect the negative
(–) battery lead first and reconnect it last.
NOTICE If boost charging never use anything
but a 12-volt charger, see page 188.
Never reverse the polarity of the bat-
tery by connecting the leads to the
wrong terminals. The red, positive
lead connects to the positive (+) termi-
nal, and the black, negative lead to the
negative (–) terminal.
Serious damage can occur to the car´s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.
The nut on the battery clamp should
be tightened to a torque of 10 Nm.

201 Car care and technical information
Drive belts
The alternator is situated on the right-hand
side of the engine, adjacent to the bulkhead.
It is driven via a Poly-V-belt from the crank-
shaft pulley.
The Poly-V-belt also drives the water pump,
the A/C compressor and the steering servo
pump.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
See also page 59, ”Warning, charging”.
WARNING
Keep hands and clothing clear of drive
belts when engine is running.
Always stop the engine before
inspecting drive belt.
The radiator fan is electric and can
start even when the engine is
switched off.NOTICESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

204 Car care and technical informationChanging bulbs
Check that the new bulb is working when fin-
ished.
Use only "Long Life" bulbs.
Headlight aiming, see page 247.
Xenon headlight3Xenon headlights produce roughly twice as
much light as halogen bulbs and have a sig-
nificantly longer service life.
The lamp units consist of a gas discharge
lamp containing xenon. When the lights are
switched on a very high voltage activates
the xenon gas. The lamps soon reach full
intensity.
Cars with xenon headlights have automatic
levelling. The levelling system comprises
two sensors on the front axle, one on the
rear axle and a control unit under the head-
light housing. Headlight alignment is regu-
lated automatically to prevent dazzling
oncoming traffic. Alignment is also adjusted
during braking.
WARNING
Before changing a bulb in the engine bay,
switch off the engine to avoid danger of
fingers and hands being injured by
moving parts.
The radiator fan can start up even when
the engine is switched off.
Xenon headlights3 are high voltage
and must therefore be changed at a
workshop. We recommend that you
contact an authorized Saab work-
shop. Work involving high-voltage
components is potentially lethal.NOTICE Since the headlight lenses are made
of plastic, rinse dried-on dirt with
water and allow it time to soften up
before cleaning the lenses. Avoid
rubbing the lenses when dry and
never use solvents.
Use de-icer spray instead of scraping
the ice off.
NOTICE Do not fit bulbs with a higher rating
than 55 W, since the headlight reflec-
tor and the wiring of the car are not
designed for a higher wattage.
Switch off the ignition before chang-
ing a bulb, to avoid possible short-cir-
cuiting.
Do not touch the glass of the bulbs
with your fingers. The oil on your skin
can shorten the life of the bulb.

217 Car care and technical information
Maxi 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 dam-
aged. 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:
DICE controls (among other things):
Front lights and interior lighting
Instrument illumination
Intermittent wiper operation
Electric heating of rear window and door
mirrors
Cooling fansTWICE 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 seat
The 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 mod-
ules 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. We recommend that you contact
an authorized 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 a
workshop. We recommend that you con-
tact an authorized Saab dealer.

236 Car care and technical informationChanging 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 sup-
port 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 for-
ward 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.

237 Car care and technical information
To 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 under-
neath 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).
Remove the wheel bolt caps and 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.
NOTICEApply the jack only to the jacking points
indicated on the body.Position for jack

242 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 thor-
oughly 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
closed.
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
corrosion 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 nec-
essary tools and materials, such as primer,
touch-up paint and brushes, are available
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 possi-
ble, 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 surround-
ing paintwork.
Stir both primer and touch-up enamel thor-
oughly before use and allow each coat to
dry before applying the next.

244 Car care and technical informationFault 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 a workshop. We recom-
mend that you contact 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).
