inflation pressure AUDI A8 2013 User Guide

tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or
more .
The performan ce of low-aspe ct-ratio tires is
particularly sensitive to improper inflation
pressure . It is therefore important that low
aspect ratio tires are inflated to the specified
pressure and that the inflation pressure is
regularly checked and maintained . Tire pres­
sures should be checked at least once a
month and always before a long trip
¢ page 2 55, Checking tire pressure .
What you can do to avoid tire and rim
damage
L ow aspect ratio tir es can be damaged more
eas ily by impact with potho les, curbs, gu llies
or r idges on the road, part icu larly if the tire is
under inflated.
In order to minimize the occurrence of impact
damage to the tir es of your veh icle, we recom­
mend that you observe the following precau­
tions :
- Always maintai n recommended inflation
pressures . Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary.
- Drive carefully on roads with potholes, deep
gullies or r idges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso
ca use damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
autho rized Audi dealer. Replace a damaged
t ir e as soon as possible.
- Inspect yo ur 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 tire failure . If you be lieve that a
t ir e may have been damaged, replace the
t ir e as soon as poss ible .
- These tires may wear more quick ly than oth ­
ers .
- Please a lso remember that, while these tires
deliver respons ive handling, they may ride

less comfortably and make more noise 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 conditions .
If
you drive under those circumstances, you
shou ld equip your vehicle w ith all-season or
winter tires, which offer better t raction unde r
those conditions. We suggest you use the rec­
ommended snow or all- season tires specified
for your vehicle, or their equivalent.
Refer to~
page 264 for more detailed infor ­
mation regarding winter tires.
Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith t ire pressure monitoring syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended
by the vehicle man ufacturer on the vehicle
placard or tire inflation pressure labe l. (If your
vehicle has tires of a different size than the
s iz e in dicated on the vehicle placard or tire in­
flat ion pressure label, you should determine
the proper tir e inflation pressure for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one o r more of your
tires is s ignificantly under-inflated. According­
l y, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possible, and inflate them to the
proper pressure . Driving on a significantly un ­
der-inflated tire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al-
so reduces fuel effic iency 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 maintenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale .
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction 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 ex ists.
When the malfunct ion 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 a lternate tires or whee ls 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
App lies 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. 209 Display: underinflation warning
Fig. 210 Disp lay: System malfunction
Using the ABS sensors, the tire pressure moni ­
toring system compares the tire tread cir cum­
ference and vibration character istics of the in ­
dividua l tires. If the pressure decreases in one
o r more t ires, this is ind icated in the instru­
ment cluster with a warning symbol
[«E and a
message ~
fig. 209.
The tire pressure monitoring system must be
reset via MMI each t ime the press ures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle
c::> page 269. 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
c::> page 2 53.
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
c::> page269.

tor light

page 269. If the indicator light does not
turn off or if it turns on short ly thereafter, im­
mediately drive your vehicle to an authorized
Audi dealer or authorized repair facility to have the malfunction corrected .
A WARNING
-If the t ire pressure indicator appears in
the instrument cluster d isplay, one or
more of you r tires is s ignificantly 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 tire pressure label ¢
page 253. 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.
- T he driver is responsible for ma inta ining
the corre ct tire pressures. You m ust
check the t ire pressures regularly .
- Under certain cond itions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads) , the pressure monitor indi­
cator may be de layed .
- Ask your author ized Audi dealer if run ­
flat tires may be used on your vehicle.
Your vehicle regist rat 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.
