shortly thereafter, immediately drive your ve­
h icle to an authorized Audi dealer or author­
ized repair facility to have the malfunction
corrected.
.&, WARNING
- If the t ire pressure indicator appears in
the instrument cl uster d isplay, one or
more o f 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 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~
page 234 . Driving on a
significantly under-inflated tire ca uses
the tire to overhea t 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 mainta ining
the correct tire pressures. You must check the tire pressures regularly .
- Under certain cond itions (such as a spor ­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi­
cator may be de layed .

Reset tire pressure monitoring system
App lies to vehicles: with tire pressure mon itor ing system
If the tire pressure is adjusted, wheels ore ro­
tated or changed, the TPMS must be reset via
