2013 AUDI A8 warning

If yo u have a flat tire, see notes on spa re
wheel
¢ page 260 .
P lease always remember th at w inte r ti res may
have a lower speed rating than the t ires origi­
na lly installed on your vehicle at the time it
was manufactured. Please see ¢
page 262,
Speed rating (letter code) for a list ing of the
speed rat ing letter codes and the m aximum
speed at which the tires can be driven .
The speed rating letter code( ¢
page 252) is
on the s ide wall of the tire ¢
page 260.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
t ires leading to an acc ident and serious
personal in jury to you and yo ur passen­
gers .
& WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
rep laced immed iate ly .
- Winter tires have max imum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for wh ich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your d rivi ng to the road and
t raffic conditions. Neve r let t he good ac­
celeration of the winte r tires and all-whee l
drive tempt you into taking extra r is ks. A l­
ways remember:
Tire s an d wheel s 265
-W hen braking, an a ll-wheel drive vehicle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions.
@ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the front
whee ls, and o nly to certain tire sizes . Ask your
authorized Aud i dea le r on which tire sizes
snow c hains can be used.
If you a re go ing to u se snow chains, then you
must install them on the front whee ls at
least.
The snow chains mus t have low-profile links
and must not be th icker than 0 .4 inch
(10,5 mm) , includ ing t he lock.
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
¢ (D . For safety reasons cover caps must then
be fitted over the wheel bol ts . These a re ava il­
able from autho rized Aud i deale rs .
A WARNING
Usi ng the wrong snow chai ns for your vehi­
cle o r insta lling them incorrect ly can in­
crease the r isk of loss of cont ro l leading to
serious pe rsonal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in ­
structions provided by the snow chain manufacturer .
- When drivi ng with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .

26 6 T ire s and whee ls
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging t ires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into d irect con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension should
malfunction, do not mo unt or use snow
cha ins beca use the veh icle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the veh icle.
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with All Wheel Drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
cor rectly .
In certain circumstances, you may not use
wheel bolts from a different vehicle - even if it is the same model
~ page 298.
A WARNING
Imprope rly tightened o r maintained wheel
bolts can be come loose caus ing loss of control, a col
lision and serio us personal in­
jury.
- Always keep the wheel bo lts and the
threads in the whee l hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driv ing if greased or
oiled, even if t ightened to the specified
torque.
- Only use wheel bolts that belong to the rim being installed .
- Never use different wheels bolts on your
veh icle.
- Always ma intain the correct tightening
torque for the whee l bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be ­
come loose .
(D Note
The specified torque for the whee l bolts is
90
ft l b (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago ­
nally . After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualif ied workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
ratio tires . These tires have been thoroughly
tested and been se lected specifically fo r your
model for their superb perfo rman ce, road fee l
and hand ling under a variety o f driving condi­
tions. Ask your authorized A udi dealer for
more details .
T he low aspect ratio of these tires is ind icated
by a numera l of
55 o r less in the tire's s ize
designation. The numeral rep resents the ratio
of the tire's sidewa ll height in relation to its
ll-

268 Tires and wheels
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

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
