tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
re placed as soon as possible .
[ i J Tips
• If you notice that the wheel bolts are corroded and diff icult to turn
wh ile chang ing a tire, they shou ld be rep laced before you check the
tightening torque. .,_

- Engage the parking brake to prevent your vehicle from
rolling unintentionally.
- Move the
selector lever to position P .
- Position the jack below the door sill under the mounting
point
that is closest to the wheel to be changed
~ page 338, fig. 272.
- Extend the
jack under the lifting point on the door sill until
its arm is positioned directly under the lifting point~ &.
- Align the jack so that its arm@=> fig. 273 engages in the
designated lifting point in the door sill and the movable
base ® lies flat on the ground. The base @ must be
vertical under the lifting point@.
- Wind the jack up further until the flat tire comes off the

The jack must be installed only at the places indicated=::> page 338,
fig. 272. There is exactly
one location fo r each wheel. The jack must

Taking the wheel off/installing the spare
Follow these instructions step-by-step for changing the
wheel
Fig. 274 Changing a
wheel: using the
screwdriver handle
(with the blade
removed ) to turn the
bolts
Fig . 275 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
aside on a
clean surface => fig. 274 .
- Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt hole=> fig. 275 . -
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 screwdriver handle to
screw in and tighten all wheel bolts
slightly.
- Remove the alignment pin and insert and tighten 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 bolt wrench to tighten all wheel bolts firmly
=> page 338. Tighten them crosswise, from one bolt to
the (approximately) opposite one, to keep the wheel
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 screwdriver 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 341.
• 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 hub.
Remove all dirt from these surfa ces before remounting the wheel. •

Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
w ith their tread pattern pointed in the right direction .
Using a spare tire w ith a tread pattern intended for
u se in a specific direction
When using a spare tire w ith a tread pattern intended for use in a
spec ific direction, please note the fo llow ing:
• The d irect ion of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direct ion, use
t he spare t ire only temporar ily since the tire w ill no t be ab le to
achieve its optimum pe rformance character istics with rega rd to
aquap lan ing, no ise and wear.
• We recommend that you pay particular attent ion to t his fact
during wet wea ther and that you adjust you r speed to match road
conditions .
• Rep lace the flat tire w it h a new one and have it ins talled on your
vehicle as soon as poss ible to resto re the handling advantages of a
unidirectio na l tire .•
Notes on wheel changing
Please read the in forma tion => page 318, "New t ires and replacing
tires and wheels" if you are going to use a spare t ire which is different
from the tires on yo ur vehi cle.
After you change a t ire:
• Check the tire pressure on the spare immediately after installa­
tion.
• Have the wheel bolt t ightening torque checked with a torque
wren ch as soon a s possible by your authorized Audi dealer or a qua l­
i fied serv ice stat ion.
Safety first • 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 replac ed before you check
the tightening torque.
• R epla ce the flat tire with a new one and have it install ed on your
