When should I check the tir e pressure?
The correct ti re pressure is especially i mpor tant a t high speeds . The
pressure should therefore be checked at least o nce a month and
a lways before star tin g a j ourn ey.
When should I adjust the tire pressures?
Adjust the tire pres sure to the loa d you are ca rrying. After changing
a wheel
or replacing whee ls you have to adjust the tire pressures on
a ll whee ls. In addition, y ou must the n ini tia lize the new tire pres ­
sures in the tire pressu re monitoring system*:::::,
page 253.
& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure, loss of control , collision, serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster , stop and in spect the tire s.
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorre ct t ire pressures and /or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pre ssure s for all
tires on the vehicle . The appli cable pressure values are located on
a sticker on the driver' s side B -pillar.
• Onl y when all tires on the vehicle are filled to the correct pres­
sure , the tire pre ssure monitoring system* can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it is essential that the driver observe
the spe cified tire pressure values for the tires and the correct pres­
sures for the function of the tire pre ssure monitoring sy stem *.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off.
& WARNING (continued )
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation, sudden tire failure and lo ss
of control .
• Excessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high , the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest servi ce station
to che ck the tire pres sure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
va lves. To prevent this, always ma ke sure that fac tor y in st alled va lve
stem caps on all wh eels are securely mounted on the valv e.
'£> For the sake of the environment
Underinflated tires w ill also increase the fue l consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehic le and
any tire can ca rry. A vehicle that is overloaded wil l not handle wel l
and is more difficu lt to stop . Overloading can not on ly lead to loss
of vehic le contro l, but can also damage important parts of the
ve hicle a nd can l ead to sudden t ire fa ilure, i nclud ing a b lowout an d
sudden deflation that can cause the vehicle to crash .

than the size indicated on the vehicle placard or tire inflation pres­
sure label, you should determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system* (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under-inflated. Accord ingly, when the low tire pressure te lltale illu­
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly
under -inflated tire causes the tire to overheat and can lead to tire
failure . Under -inflation also reduces fuel efficiency and tire tread
life, and may affect the vehic le's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
il lumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS ma lfunction indi­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the tellta le wi ll
flash for approximately one minute and then remain continuously illuminated. This sequence wil l continue upon subsequent vehicle
start -ups as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detec t or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the
installat ion of replacement or a lternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the rep lacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•

Introduction
The tire pressure monitoring system* monitors air pres ­
sure in all four road wheels while the vehicle is moving.
As soon as the tire pressure monitoring system* senses a signifi­
cant loss of air pressure in one or several tires, text messages and
yel low symbols appear in the instrument cluster disp lay to alert the
driver. The ) warning light in the instrument cluster comes on
when the tire is significantly underinflated
:::> page 17 .
The warning light Cl' also i lluminates in the case of a system
malfunction.
Be aware that tire pressure is a lso dependent on the temperature of
the tire. For every 18
°F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1.5 psi (0 .1 bar). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when the temperatu re of the t ires
is roughly the same as the ambient air temperature .
I n order to keep the tire pressure monitoring system * properly ca li­
brated, tire pressure on all four tires shou ld be checked at regu lar
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure)
:::> page 256 .
The tire pressure is shown on the label located on the driver's side
B -pillar (visible when the door is open) .
& WARNING

& WARNING (continued)
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when the temperature of
the tires is about the same as ambient air temperature and set to the
recommended inflation pressure as specified on the tire pressure
label =>
page 238.
• The factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system *. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system * helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged . The valve core, nut, valve sealing and seal washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system*.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. •
Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system* to the load you are carrying.

[ i) Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards=>
page 256.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air tempera ture.
• The yellow symbol disappears, when the tire pressure is
correc ted and the new pressure is stored in the system=>
page 256.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition , you
must then initialize the new tire pressures in the tire pressure moni ­
toring system*=>
page 257. •

Storing tire pressures
Correct storage of specified pressure is the basic require ­
ment for reliable tire pressure monitoring.
Fig. 154 SET-button :
Tire pressure moni­
toring system
In order for the tire pressure monitoring system* to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, for example when the
load condition of your vehicle changes . Proceed as follows:
Correcting tire pressure
Check the pressure in the tires.
Adjust air pressure as needed to comply with the infor­ mation on the label located on the driver's side B -pillar
(vis ible when the door is open).
Saving tire pressures
Turn on the ignition.
Press the button=> fig. 154 for app roximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times.
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved.
After the pressures are saved, the tire pressure monitoring system* measures the current tire pressures and saves them as the new
specified pressures.
[ i J Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located on the driver's side B-pillar (visible when
the door is open). The tire pressure label lists the recommended cold tire inflation pressures for the vehicle at its maximum capacity
weight and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for normal load
conditions, please see chapter
=> page 238. .,_

S yst e m m alfun ctio n
If the .J., warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously illuminated and
additional ly the T ~~ fig. 155 symbol appears in the display, the
tire pressure mon itoring system* is not available. This can have
various causes.
• If the message appears at the end of the lear ning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a wheel sensor were
insta lled.
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system*.
• A whee l change was made but the button

Tire Mobility System ..

Fuses and bulbs -
------------------
The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle.
Fuses with the proper ampere ratings are available at your autho­
rized Audi dealer.
& WARNING
Never replace a fuse with one that has a higher amperage rating .
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
0 Note
• On no account should fuses be repaired (e.g. patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause for the repeated short circuit or overload tracked and
fixed. •
