2000 SAAB 9-3 wheel torque

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).

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.
