Taking the wheel off /installing the spare
Follow these instructions step-by-step for changing the
wheel
Fig . 289 Changing a
wheel: using the
screwdriver handle
!with the blade
removed) to turn the
bolts
Fig . 290 Changing a
wheel: alignment pin
inside the top hole
After you have loosened all wheel bolts and raised the
vehicle off the ground, remove and replace the wheel as
follows:
Removing the wheel
- Use the hexagonal socket in the screwdriver handle to
completely remove the topmost wheel bolt and set it
as ide on a
cl ean surface => fig. 289. -
Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt
hole => fig. 290.
- Then remove the other wheel bolts as described above .
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the spare wheel
- Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdr iver handle to
screw in and tighten all wheel bolts
slightly.
- Remove the alignment pin and insert and t ighten the
remaining wheel bolt slightly like the rest.
- Turn the jack handle counter-clockwise to lower the
vehicle until the jack is fully released.
- Use the wheel bo lt wrench to tighten all wheel bolts
firmly=> page 354. Tighten them crosswise , from one
bolt to the (approximately) opposite one, to keep the
w heel centered .
[ i ] Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts .
• Pull the reversible blade from the s crewdriver before you use the
hexagonal socket in the handle to turn the wheel bolts.
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way ::::>
page 357.
• The wheel bolts should be clean and easy to turn . Check for dirt
and corrosion on the mating surfaces of both the wheel and the -.,

What do I do now? -
----------------
•
hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern intended for use
in a specific direction
When using a spare tire with a tread pattern intended for use in a specific direction , please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire .
• If the spare tire has to be installed in the incorrect direction, use
the spare tire only temporarily since the tire will not be able to
achieve its optimum performance characteristics with regard to
aquaplaning, noise and wear.
• We recommend that you pay particular attention to this fact
during wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible to restore the handling advantages of a
unidirectional tire. •
Notes on wheel changing
Please read the information =:> page 336, "New tires and replacing
tires and wheels" if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire :
• Check the tire pressure on the spare immediately after installa­
tion. •
Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a
qualified service station .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nm}.
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds .
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
=:> page 336, "New tires and replacing tires and
wheels".
• Always make sure the damaged wheel or even a flat tire and
the jack and tool kit are properly secured in the luggage compart­
ment and are not loose in the passenger compartment.
• In an accident or sudden maneuver they could fly forward,
injuring anyone in the vehicle .
• Always store damaged wheel, jack and tools securely in the
luggage compartment . Otherwise, in an accident or sudden
maneuver they could fly forward, causing injury to passengers in
the vehicle .
• Do not use commercially available tire sealants. Otherwise, the
electrical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni ­
toring system will have to be replaced by a qualified workshop. •

&, WARNING (continued )
• The engine compartment of any motor vehicle is a potentially
hazardous area . Never reach into the area around or touch the
radiator fan . It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed . The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehi cle .
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle . The jack suppl ied with the
vehicle is not adequate for this purpose and could collapse causing serious personal injury .
• If you must work underneath the vehicle with the wheels on
the ground , always make sure the vehicle is on level ground , that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in
"P " (Park position ) and the park brake is firmly
applied.
W For the sake of the environment
• Cha ng ing the eng in e sett ings will adverse ly aff ect em iss ion
