A WARNING ,~
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label¢
page 249. Driving on a
signif icantly 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 un­ paved roads), the pressure monitor indi­
cator may be delayed.
-Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
.
(0 Tips
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on your Audi was developed using tires with
the "AO" or "RO" identification on the
tire sidewall
¢page 256. We recom­
mend using these tires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
.,. Before storing the new tire pressures, check
that the current pressures on all four tires
correspond to the specified values and
Tires and wheels 265
adapt the pressures to the current load
¢page 249 .
.,. Switch on the ignition.
.,. Select in the MMI:
ICARI function button >
Car systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Do not store the tire pressure if there are
snow chains on the tire. Otherwise, a sys ­
tem malfunction may occur .

vehicle.
It must not be swapped with a com­
pact spare tire from another type of vehicle .
Snow chains
Fo r technical reasons, the use of snow chains
on the compa ct spare tire is
not p ermi tte d .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare whee l w ith tire instead of a
rear tire. Install the snow
chains on the rear tire and use it to replace
the defect ive front tire.
A WARNING
=
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
d icators.
- If the spare tire is more than 6 years old,
use it only in an emergency and with ex­
treme caution and careful driv ing.
- 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 wheel and tire.
-After mounting the compact spare tire, the t ire pressure must be checked as
soon as possible. The tire pressure of the
compact spare t ire must be 4.2 bar; oth­
e rwise, you risk having an acc iden t.
- Do not drive faster than 50 mph (80 km/
h). Yo u ris k having an accident.
- Avoid full-thrott le acceleration, heavy

- For technical reasons, the use of tire
chains on the spare tire is not permit ted .
If it is necessary to drive with t ire chains,
the spare wheel must be mounted on the
front ax le in the event of a flat in a rear
tire. The new ly available front wheel
must then be installed in place of the
rear whee l with the flat tire. Installing
the t ire chain before mounting the whee l
and tire is recommended.
- Loose items in the passenger compart­ ment can cause se rious personal injury
during hard braking or in an accident. Never store the inflatable spare tire or
