•
- Let the compressor run until it has reached 50 PSI (3.5
bar). Switch the compressor off after running for 8
minutes at the most -danger of overheating!
& WARNING
The compressor and the tire filler hose can become extremely hot
while they are running -danger of burns!
0 Note
Switch the compressor off after running for 8 minutes at the most -
danger of overheating! Allow the compressor to cool down for a few
minutes before you use it again.
[ i] Tips
The compressor must not be connected to the cigarette lighter
socket, as this socket does not provide the required power .•
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 359, "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 workshop.
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 120 ft lb (160 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 359, "New tires and replacing tires and
wheels". ..
