Wheels
circumference as the regular
tires.
A_ WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
- Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.

-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents .
-If you install wheel covers on the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.

Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Hav e an authorized Audi dealer

ty check the wheel alignment if
there is unusual wear .

place away from the vehicle and well away
from the road and traffic.
- Make sure jack position is correct, adjust
as necessary and then continue to raise
the jack.
- If work has to be done under the vehicle,
ensure that it is safely supported on suita­
ble stands -risk of injury!
- Never start the engine when the vehicle is
on the jack -risk of accident!
