227 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, 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.

250 Car care and technical informationHeadlight aiming The vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be
re-aimed, we recommend that you take it to
your Saab dealer for service, however, it is
possible for you to re-aim your headlights as
described in the following procedure.To check the aim, the vehicle should be
properly prepared as follows:
 The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
 The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
 The vehicle should be placed so it is per-
pendicular to the wall or other flat surface.
 The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.  The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
 The vehicle should not have any snow, ice
or mud attached to it.
 Tires should be inflated to the prescribed
pressure.
 Close all doors.
 Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
be correctly aimed if the low beam lamps
are aimed properly.
WARNING
Before checking/adjusting the headlight
aiming, 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.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.
