215 Car care
When changing a wheel, take the tool kit out
first, then the spare wheel.
Changing a wheel
NOTE
To avoid damaging an alloy wheel with a
flat tire, this can be placed outside up in
the spare-wheel well but only while driv-
ing to the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 142.
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 a crash.
Do not use the jack for any purpose
other than for jacking up the car.
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 cor-
rect tightening torque cannot be
achieved.

216 Car careWhen it is time to raise the car, apply the
jack to one of the four jacking points (front or
rear) located beneath the sills.
If a floor jack is used it can be applied to the
standard jacking points used by the dealer
or centrally under the front of the engine
subframe. If the car is equipped with a trailer
hitch, the jack can also be placed under the
hitch. 1 Put the car in 1st gear (automatic trans-
mission: move selector to the P position)
and apply the parking brake.
Saab 9-3 Viggen: The front and rear
jacking points are located behind covers
that must be removed. See page 217.
2 Wind the jack up to a suitable height
before placing it under the recess in the
sill.
3 Make sure that the jack fully engages
the recess in the sill and that the base of
the jack is steady and flat on the ground.
4 Turn the jack handle clockwise until it
just begins to lift the car. 5 Remove the wheel cover (where appli-
cable). Loosen the wheel bolts by half a
turn.
6 Turn the jack handle to raise the wheel
clear of the ground. Remove the wheel
bolts and lift off the wheel.
7 Clean the contact surfaces between the
rim and hub.
8 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs).
Tighten the studs enough for the studs
and wheel to be seated correctly.
See page 218 for sequence.
9 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)NOTE Do not position the jack under the rear
axle or under the rear floor.
Only use the points specified on
page 217.

10 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 172. NOTE
When refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
NOTEDo not overtighten the bolts using an
impact wrench: not only can this damage
the wheels but it can also make it impos-
sible to undo the bolts using the wheel
wrench in the car’s toolkit.NOTESaab 9-3 Viggen: The minimum permis-
sible wheel diameter is 16”, due to the
size of the brake discs.

Position for jack, Saab 9-3 Viggen. The front and rear jacking points are located behind
covers that must be removed. Remove the covers by taking hold of the lower edge and
pulling outwards. When replacing the covers, fit the catches along the top edge first and
then press home the cover.
