157 Starting and driving
Trailer weightMaximum recommended trailer weights for
different gradients, for best comfort and
driveability for manual and automatic cars,
are shown in the drawing.
Make sure you are familiar with the law
regarding speed limits for towing, maxi-
mum trailer weights, trailer-braking
requirements, and also any special
driving-license provisions
(see also page 222).
The specified trailer weights and gradients
assume you are operating in hilly terrain and
therefore apply only to short trips.Recommendations for cars with auto-
matic transmission
The following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86°F (30°C).
The following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 104°F (40°C).
When negotiating long hills, bear the follow-
ing important considerations in mind:
Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a trailer, as this will increase fuel con-
sumption and risk overheating the transmis-
sion.
NOTESaab 9-3 Viggen cannot be equipped
with a trailer hitch because of the design
of the body and chassis.
WARNING
When towing a trailer, do not attempt to
negotiate a hill having a gradient in
excess of 15%. The weight distribution
over the front wheels of the car will be
insufficient to prevent wheelspin, making
further progress impossible.
In addition, the parking brake may not
always be able to hold the car and trailer
securely, with the result that the wheels
can start to slide downhill.

188 Car careMAXI 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.
DICE controls, among other things:
 Front lights and interior lighting.
 Instrument illumination.
 Intermittent wiper operation.
 Electric heating of rear window and door
mirrors.
TWICE controls, among other things:
 Central locking.
 Car alarm (Anti-theft system).
 Engine immobilizer.
 Auto checking 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 enhances fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTEIf 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.
