2003 SAAB 9-5 heating

169 Starting and driving
If you move the selector lever from D to L, downchanges will follow
a set pattern to avoid damaging the engine or transmission.
Manual gear-changing is not recommended on slippery roads.
If one of the drive wheels spins excessively, the engine torque will
be reduced to avoid damaging the transmission.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load and the present temperature of the transmis-
sion. The function is available in Normal and Sport modes.
The changes occur at a higher engine speed and the car remains in
the same gear for longer, if the transmission control module senses
that the load has not decreased. These gear-change patterns pre-
vent unnecessary changing up and down, when for example driving
up or down long slopes with a trailer or caravan, and to prevent over-
heating the transmission oil. The adaptive gear-change function is
also selected automatically when the transmission oil becomes too
hot, to protect the transmission itself from damage and to lower the
oil temperature.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced so much that the function is no longer
required.
 ”Automatic transmission, fault indicator” appears on main
instrument panel, see page 165.

183 Starting and driving
Use Normal mode when driving with a trailer
or trailer on hilly roads. The adaptive gear
change pattern function will prevent the
transmission from overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following can also occur:
 the A/C-compressor can be shut off
 the gear-change pattern is changed
 the CHECK message TRANSMISSION
OVERHEATING can appear on the SID
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so, switch off the engine and
open the hood. Wait several minutes and
then turn on the ignition to check that the
message has been extinguished. When
continuing your journey, select manual
mode (M) and a gear in which the engine
speed is about 3,000 rpm (see page 168). 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.
Driving considerations Always take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also ”Driving with a load” page 187.
If the car has automatic transmission, select
position D when ascending steep hills. This
ensures that the adaptive gear change pat-
terns are operational, see page 169. Use
position D or L for steep descents.
WARNING
Remember to use engine-braking (selec-
tor position D or L) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!
NOTICEIf the ”Automatic transmission, fault indi-
cator” indicator comes on, cease
towing until the problem has been recti-
fied.

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.
