flat tire AUDI A7 2012 Owner's Manual

250 Tires and wheels
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi ­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunction
telltale after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire p ressure mo nitoring syste m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 181 Display : underinflatio n warning
Fig. 182 Display : Syste m mal functio n
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
d ividual tires.
If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster with a warning symbol
'9] and a
message ¢
fig . 181.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad- justed
(e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle ¢
page 251. You
can find the recommended tire pressures for
your vehicle on the label on driver 's side B-pil­
lar ¢
page 235 .
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset

and reset TPMS via MMI.
••MIS, ( Ti re Pressure Monitoring System) Tire
pressure! System malfunction .
If IIMIS, appears after switching the ignition
on or while driving¢
fig. 182 and the indica­
tor light
'9] in the instrument cluster blinks
f or approximately one minute and then stays
on, there is a system malfunction . See your
authorized Audi dea ler as soon as possible .
A WARNING
--If the tire pressure indicator appears in
the instrument cluster display, one or more of your tires is significant ly under­
inflated. Reduce you r speed immediately
and avoid any hard steer ing 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 235. 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 t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be de layed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registrat ion becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or acc idents
cou ld also resu lt.
(0 Tips
- The t ire pressure monitoring system
stops working when there is an ESP/ABS malfunction.
- Using snow chains may result in a system malfunction .
- To ensure a proper TPMS function use
AUDI Origina l Tires wh ich are marked
with "AO" or "RO" on the tire sidewall.
¢page 242.
- The t ire pressure monitoring sys tem on
you r A udi was syntoni zed using tires w ith
the "AO" or "RO" identific ation. We rec­
omme nd using these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monito ring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the T PMS must be reset via
MMI .

Using the spa re tire (compact spare tire )
The compact spare tire is only intended for
emergencies until you can reach a repair shop.
Replace it as quickly as poss ible with a stand­
ard wheel and t ire .
There are some restrictions on the use of the
compact spare t ire. The compact spare t ire
has been des igned specifically for your type of
vehicle.
It must not be swapped with a com­
pact spare t ire from another type of veh icle .
Snow chain s
For technical reasons, the use of snow chains
on the compact spare tire is
not perm itted .
What do I do now? 253
If you do have to drive with snow chains and a
front tire fails, mount the spare wheel with
tire instead of a rear tire. Install the snow
chains on the rear tire and use it to rep lace
the defect ive front tire.
A WARNING
- Never use the spare t ire if it is damaged
or if it is worn down to the tread wear in­
dicators .
- 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 wi th the
normal whee l and tire.
- After mounting the compact spare t ire,
the t ire pressure must be checked as
soon as possible. T he tire pressure of the
compact spare tire must be 4 .2 bar; oth­
erwise, you risk having an accident.
- Do not dr ive faste r than 50 mph (80 km/
h). You ris k having an accident.
- Avoid full-thrott le accelera tion, heavy
braking, and fast cornering . You risk hav ­
ing an accident.
- Never drive using more than one spare
wheel and tire . You risk having an acci ­
dent .
- Normal summer or winter t ires must not
be mounted on the compact spare wheel
rim.
- For technical reasons, the use of tire chains on the spare tire is not permitted.
If it is necessary to drive with t ire chains,
the spare wheel must be mounted on the
front axle in the event of a flat in a rear
tire. The newly available front wheel must then be installed in place of the
rea r whee l w ith the flat tire . Installing
the t ire cha in before mounting the whee l
and tire is re commended.
- Loose items in the passenger compart­
men t can cause se rious personal injury
during hard brak ing or in an accident. •
