2013 AUDI A8 change wheel

The correct tire pressure for the spare wheel is
l ocated on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
veh icle equ ipment dur ing the model yea r, a l­
ways compare the tire size designation on the
tire pressure label on your vehicle wit h the
tires on your vehicle . Make s ure that the tire
size information on the veh icle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be ­
longs to someone else or you bought the veh i­
cle with different rims/tires or you boug ht the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing su re that
l oad l imits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR") . The Gross Ax le Weight Rat ­
ing ("GAWR") is the maximum load that can
be app lied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle We ight Rating are listed on the
safety compliance st icker label located on the
driver's side B-p illar . The t ire pressure label on
your Aud i lists the maximum combined
weight of a ll of the occupants and luggage or
other cargo that the vehicle can carry. For the
l ocat ion of the tire pressure labe l

A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Car rying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of a loss of veh icle con­
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
t rol and a crash.

-Always make sure that the total load be­
ing transported - includ ing the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
A WARNING
- Inco rrect tire pressures and/or underin­
flation can lead to a ser ious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, caus ing loss of veh icle contro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressvre label located on driver's side 8-pil ­
lar.
T he recommended tire pressures are on the
ti re pressure label and in the table
c;, page 253, Cold tire inflation pressure .This
means that the pressure m ust be checked and
adjusted when the tire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is h igher when the tire
has warmed up t han when it is "cold."
It is the inflation pressure in a "cold" t ire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendat io ns
c;, page 253 . The
ti res wo uld then be unde rinfl ated and co uld
fail suddenly.
T he tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
max imum capacity for the new, or ig inal
equipment tires that were on your vehi cle at

-Only when a ll tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the d river
observe the specif ied tire pressure values
for the tires and the co rrect p ress ures for
the f un ct ion of t he tire pressure mo nitor­
ing sy stem*.
- Always inflate ti res to the recommended
and co rrec t tire pressu re befo re dr ivi ng
off.
- Driv ing wi th under infla ted ti res bend
more, letti ng them get too ho t res ulting
in t read separation, sudden t ire fail ure
and loss of control.
- Excessive spee d and/ove rloading can
ca use heat bui ld -up, sudden tire fa il ur e
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematu rely an d the
vehicle will not hand le we ll.
-If the t ire is no t flat and you do no t have
to change a w heel imme diate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Driving without va lve stem caps ca n cause
damage to the t ire va lves. To prevent this,
always make s ure that facto ry installed
valve stem caps on all wheels a re secure ly
mounted on the va lve .
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can carry .
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop . Overload ing
can no t on ly lead to loss o f vehi cle con tro l,

but can also damage important parts of the
vehicle and ca n lead to sud den tire fai lure, in ­
clud ing a b lowout and s udden def lation that
can cause the vehicle to cras h.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gross Vehicle We ight Rating
("GVWR ") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coo lant and other fluids plus
maximum load . The max imum load includes
the number of passenge rs that th e vehicle is
i n tended to car ry ("seat ing capa city") wi th an
ass umed we igh t of 150 lbs (68 kg) fo r each
passenger at a designated seating posi tion
and t he tota l weight of any luggage i n the ve­
hicle . If you tow a trai ler, the weight of the
tra iler hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
T he
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
T he Gross Vehicle Weight Rating and the
G ross Ax le Weig ht Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar. Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rea r fo r
total seating capacity of 5 . Vehicles with pow­
er ind iv idual rea r seats* have 4 seat ing pos i­
tions, 2 in the front and 2 in the rea r fo r total
seat ing capac ity o f 4. Each seating position
has a safety belt~
page 144, Safety belts.
The fact that there is a n uppe r limit to you r
vehicle's G ross Vehicle We ight Rating means
t h at the to tal weig ht of whatever is bei ng car ­
ried in the vehicle ( in cl ud ing t he weight of a

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
