2014 AUDI A8 TPMS

266 Tire s and wheels
or ridges on the road, part icu larly if the tire is
underinflated.
I n o rder to minim ize the o ccurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000
km) and add air if neces­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ir e as soon as possible .
- Inspect your tires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause t ire failure . If you be lieve that a
t ir e may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you drive under those circumstances, you should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or all-season tires specified
for your vehicle, or their equivalent. Refer
to
q page 263 for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, including the spare ( if provided),
shou ld be checked monthly when co ld and in­
flated to the inflation pressure recommended
by the veh icle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in­
flation pressure label, you should determine
the proper tire inflation pressu re fo r those
t i res).
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significant ly under-inflated. According­
l y, when the low tire pressure telltale i llumi­
nates, you should stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der-inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al ­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's responsibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the level to trigger illuminat ion of the
TPMS low tire pressu re tellta le .
Your vehicle has also been equipped with a
TPM S ma lfunction indicator to ind icat e when
the system is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one minute and then ..,_

remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intend ed . 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 functioning
properly . Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
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. 213 Display : underi nflatio n warning
Fig. 214 Di splay: Syste m mal functio n
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration ch arac teristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru-
Tires and wheels 267
ment cluster with a warning symbol [I] and a
message
r::!) fig. 213.
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
r::!) pag e 268. The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
<=:>page 252 .
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

have the malfunction corrected .

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 ­
ted. Damage to your vehicle or acc idents
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
Applies to vehicles: with tire pressure monitoring system
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 :
ICARI function button>
Car system s control button > Servicing &
check s > Tire pres sure monitoring > Store
tire pre ssur es > Ye s, store now .
@ Tips
Do not sto re the tire pressure if there are
s now cha ins on the tire.
