268 Tire s and wheel s
_&. WARNING
-If th e tire pressure indicator appea rs in
the instrument cluster d isplay, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or bra king
maneuvers . Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pressure to the proper pres ­
sure as indicated on the vehicle 's t ire
pressure label
q page 252. Driving on a
signif icant ly 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 ab ility .
- The driver is responsible for ma inta ining
the correct tire pressures. You must check the t ire pressures regula rly.
- Under certain cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure mon itor ind i­
cator may be de layed.
- Ask your author ized Audi dealer if r un­
flat tires may be used on your veh icle.
Yo ur vehicle regist rat ion becomes inval id
if yo u use these tires when not permit ­

cou ld also resu lt.
(D Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
you r A udi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ~
page 259 . We recom­
mend using these t ires.
Reset tire pressure monitoring system
