Saab 2005 Automobile User Manual


 
150 Starting and driving
If you move the selector lever from D to L, down shifts 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 patterns
Adaptive 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:
The engine is switched off.
The load is reduced so much that the function is no longer requi-
red.
”Automatic transmission, fault indicator” appears on main
instrument panel, see page 146.
SPORT modes
To select Sport mode, press the ”S” button on
the selector lever when the selector lever is in
position N or D.
In this mode, gear changes will take place at hig-
her engine speeds than in Normal mode, in
other words, the transmission will change up
later and change down earlier for the same
throttle (accelerator) position.
The Sport mode will be deselected if:
The S button is pressed.
The selector lever is moved to position P,R, M
or L.
The engine is switched off.
”Automatic transmission, fault indicator”
appears on main instrument panel, see
page 146.
