2000 SAAB 9-3 torque

142 Starting and drivingThe electronic control module for the auto-
matic transmission receives information on
engine torque and road speed. It also con-
trols the hydraulic pressure in the transmis-
sion to ensure that gear changing is as
smooth as possible.
The position of the selector lever is shown
by the symbols adjacent to the lever and
also by an indicator on the main instrument
panel.
The ignition key can only be removed when
the selector lever is in the P position.When the car is stationary, the engine must
be idling when the selector lever is moved.
You must have your foot on the brake
pedal to move the lever out of park. If the
accelerator is depressed while the lever is
moved, this will result in abnormal wear in
the transmission. The detent button on the selector lever has
to be pressed before the selector can be
moved between certain positions.
Three modes for the automatic transmis-
sion can be selected: Normal, Sport and
Winter.
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
Sport mode alters the angle of the throttle
valve for increased power compared to the
same accelerator position in Normal mode.
This means gear changes are made to opti-
mize the car’s performance. The SPORT
indicator light is shown on the main instru-
ment panel; see page 147).
The Winter mode is intended for use when
pulling away and driving on icy roads. In this
mode, the transmission starts in 3rd gear, to
NOTEAfter selecting a drive position, pause
briefly to allow the gear to engage (the car
starts to pull a little) before you acceler-
ate.

provide better grip, and the WINTER indica-
tor appears on the main instrument panel.
When the ignition is turned to OFF, the auto-
matic transmission will automatically revert
to Normal mode (see page 147).
Adaptive gear change pattern is a func-
tion of the Normal and Sport modes. It
allows gear changing to be suited to the pre-
vailing driving conditions. The transmission
control module senses the engine load and
temperature of the transmission and selects
one of the four available gear change pat-
terns. Unnecessary gear changes and
undesired temperature increases in the
transmission are avoided.
The automatic transmission has a special
shift pattern during the first minute after a
cold engine is started so that the catalytic
converter will reach its correct working tem-
perature more rapidlyLock-up functionThe automatic transmission has a lock-up
function, which renders the torque con-
verter inoperative in 2nd, 3rd and 4th gears.
The result is reduction in the engine speed
and, hence, fuel consumption.
When the lock-up function comes into oper-
ation, it may give the impression of an over-
drive being engaged.
Shift Lock override1 Apply the parking brake.
2 Make sure the key is in the ON position.
3 Use a small tool such as a screwdriver
and push the lever downwards so that
the detent button can be pressed
approx. 10 mm.
4 Move the selector out of position P to N.
5 Remove the tool.
6 Release the parking brake if the car is to
be moved immediately; otherwise keep
it applied.Check fuse No. 1 (see page 189). If the fuse
is OK, check the battery voltage.
If the problem was cured by changing the
fuse or battery, you do not have to contact a
Saab dealer.
If the fuse blows again as soon as the Shift
Lock feature is activated you should contact
your Saab dealer.NOTEDue to electrical problems it may not be
possible to move the selector out of the
park position, even if the ignition is ON. If
for some reason the selector has to be
moved out of the park position (i.e. to tow
the car a short distance) do as described
below.

146 Starting and drivingIf the gear selector lever is moved from position D to 1, a
change-down to 3rd gear will occur at about 110 mph (180 km/h).
A change-down to 2nd gear will occur at about 75 mph (120 km/h)
and to 1st gear at about 40 mph (65 km/h).
When position 1 is selected, all the other gears will be locked out.
Manual gear-changing is not recommended on slippery roads.
2.0 Turbo 185 hp and 205 hp: If one of the drive wheels spins
excessively, the engine torque will be reduced to avoid damaging
the transmissionKick-downWhen the accelerator is pressed down hard, a downshift to the next
lower gear will occur to provide maximum acceleration, e.g. for over-
taking.
The change-up to the next gear again will take place either when the
accelerator is released or when maximum engine speed for that
gear is reached.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load. This function applies in the Normal and Sport
modes.
The change occurs at a higher rotation speed and the gear remains
engaged for a longer period, if the control module senses that the
load does not drop. These change patterns avoid unnecessary gear
changes when, for example, driving on long inclines with a trailer,
and to prevent overheating of the transmission oil. This function cuts
in automatically if the oil becomes too hot, to protect the transmis-
sion from serious damage, and lower the oil temperature.
The adaptive change pattern function is not activated at speeds over
93 mph (150 km/h). If a pattern is in operation when this speed is
exceeded, it will be maintained until the control module senses that
a more suitable one can be activated.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced by so much that this function is no longer
required.
 “Automatic transmission fault indicator” appears on the
main instrument panel, see page 144. 1
Position 1 should be used when maximum
engine-braking is required on steep downhill
slopes and to avoid frequent gear-changing on
steep climbs.
Do not move the selector to position 1 at speeds
in excess of 30 mph (50 km/h).

168 Car careHood release handleThe handle of the hood lock is located on the
left under the instrument panel. Open the
hood in the following way:
1 Pull the release handle.
2 The hood moves to the half-locked posi-
tion and is stopped by a safety catch at
the front edge.
3 Press the lever of the catch upwards and
raise the hood.
When you close the hood you should drop it
from a height of about 8 inches (20 cm),
without slamming it.
EngineThe engine is a transverse four-cylinder
in-line engine with twin overhead camshafts
and 16 valves.
The engine is equipped with two balance
shafts that reduce engine vibration to a min-
mimum.
The balance shafts are chain-driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods. The effect occurs
twice in each revolution of the engine, coun-
teracting the vibration from its moving parts,
and at the same time reducing unwanted
engine noise.
The gearbox, located on the right (viewed
from the front), is integrated with the engine.

196 Car careWhen changing a wheel, take the tool kit out
first, then the spare wheel.
Changing a wheel
If light-alloy wheels have been fitted to the
car for several years and a change is made
to steel wheels, the threads for the wheel
bolts in the brake discs should be cleaned
before the thinner steel wheels are fitted.
The innermost threads in the holes may be
clogged with sand, salt and rust so that the
correct tightening torque cannot be
achieved.
NOTETo avoid damaging a punctured alloy
wheel this can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 129.
WARNING
 The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to support
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 an acci-
dent.
 Do not use the jack for any purpose
other than for jacking up the car.

198 Car care8 Lower the car and tighten the wheel
bolts to the correct torque in the
sequence shown (opposite pairs).
Tightening torque:
Light-alloy wheels: 80 ft.lbs (110 Nm).
Steel wheels: 80 ft.lbs (110 Nm).
Do not overtighten the bolts using an
impact wrench: not only can this
damage the wheels but it can also make
it impossible to undo the bolts using the
wheel wrench in the car’s toolkit.9 Recheck the wheel bolts after a few
miles.
Tightening torque:
Light-alloy wheels: 80 ft.lbs (110 Nm)
Steel wheels: 80 ft.lbs (110 Nm)
We advise against using wheels with open
wheel covers in winter, as the brake compo-
nents are then more exposed both to slush
and to road salt and grit.
Tire chains; see page 155.
NOTE
When refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
NOTESaab 9-3 Viggen: The minimum permis-
sible wheel diameter is 16”, due to the
size of the brake discs.
