2012 AUDI A8 Owners Manual

pressure label¢ page 239. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for maintaining the correct tire pressures. You must check the tire pressures regularly.
- Under certain conditions (such as a spor­ ty driving style, winter conditions or un­paved roads), the pressure monitor indi­
cator may be delayed.
-Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
Your vehicle registration becomes invalid if you use these tires when not permit­
ted. Damage to your vehicle or accidents
could also result.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- To ensure a proper TPMS function use
AUDI Original Tires which are marked
with "AO" or "RO" on the tire sidewall.
¢page 246.
- The tire pressure monitoring system on
your Audi was syntonized using tires with
the "AO" or "RO" identification. We rec­
ommend using these tires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monitoring syste m
If the tire pressure is adjusted , wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
~ Switch on the ignition.
~ Select in the MMI: !CAR !function button>

Tires and wheels 255
(D Tips
Before resetting the TPMS, the current
pressures of all four tires must correspond
to the specified values. Adjust the tire
pressure and reset the pressure in the tire
pressure monitoring system according to
the load you are carrying ¢
page 239.
-Do not store the tire pressures if you are
driving with snow chains. Otherwise, a
system malfunction may occur .

- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as poss ible with the
normal whee l and tire.
-Afte r mounting the compact spare tire,
