210 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 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 be done to the
car’s electrical system if a battery or
alternator lead is disconnected while
the engine is running.
The nut on the battery clamp should
be tightened to a torque of 10 Nm.

211 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 57, ”Warning, charging”.
WARNING
Keep hands and clothing well clear of
drive belts when engine is running.
Always stop engine before inspecting
drive belts.
The fan 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.

214 Car care and technical informationChanging bulbsCheck that the new bulb is working when finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 250.
Bi-Xenon headlight (certain models only)Bi-Xenon headlights produce roughly twice as much light as halo-
gen bulbs and have a significantly 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 headlight housing. Headlight alignment
is regulated 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.
Bi-Xenon headlights are high voltage and must therefore be
changed at an authorized Saab workshop. 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 head-
light reflector and the wiring of the car are not designed for a
higher wattage.
Switch off the ignition before changing a bulb, to avoid possi-
ble short-circuiting.
Do not touch the glass of the bulbs with your fingers. The oil
on your skin can shorten the life of the bulb.

Front turn signal bulbsTo change the bulb, the complete lamp unit
has to be removed.
1 Depress the catch, accessed from the
engine bay.
2 Carefully pull out the lamp unit.
3 The bulb holder has a bayonet fitting.
Grip the holder and twist it counterclock-
wise.
4 Withdraw the bulb holder from the lamp
unit.
5 The bulb also has a bayonet fitting.
Press in the bulb and twist it counter-
clockwise.
6 Fit the new bulb and check that it is cor-
rectly seated.
To re-install the lamp unit1 Align the catch with the recess in the
lamp housing holder.

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, 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 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 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.

237 Car care and technical information
Changing a wheel
WARNING
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.
Special care must be taken if the car is
on a slope – use wheel chocks!
Position chocks, one ahead and one
behind, the wheel that is diagonally
opposite to the one to be changed.
Switch on the hazard warning lights if
the car is on a road.
Apply the parking brake and leave the
car in gear (1st or reverse). Automatic
transmission: move selector to the
P position.
Ensure that everybody is out of the car
before jacking it up.
Never start the engine while the car is
jacked up.
The jack must stand on a firm, level
surface.
Stow the jack in the place provided for
it under the panel in the floor of the
trunk. Secure it properly to avoid injury
to passengers in the event of a crash.
Do not use the jack for any purpose
other than for jacking up the car.
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 now fitted, the bolt
hole threads in the brake hubs should
be cleaned before the thinner steel
wheels are fitted. It may otherwise not
be possible to achieve the required
clamping force despite tightening the
bolts to the correct torque.
