-Pull the reversible blade from the screw­
driver 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 pat­
tern is pointed the right way
<=>pag e 275.
- 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
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 ar­
row on the side of the tire.
- If the spare tire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the tire will not be able to
achieve its optimum performance character­
istics with regard to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tention 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 256, 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 .
What do I do now? 275
After you change a tire:
-Check the tire pressure on the spare imme­
diately after installation.
- 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 cor­
roded 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 re­
duced speeds.
A 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 256,
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 com­
partment and are not loose in the pas­
senger 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 compart­
ment. Otherwise, in an accident or sud­
den maneuver they could fly forward,
causing injury to passengers in the vehi­
cle. •
