• 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
detached or exchanged . Only the valve core needs to be replaced and,
if necessary, the valve and the wheel electronics replaced .
• The tire pressure monitoring system on your Audi was calibrated
usiing tires with the "AO" or "RO" identification. We recommend
using these tires.
• 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. Other­
wise the system will register a malfunction and a fault message will be displayed. For more information, contact your authorized Audi
dealer.
• Adjust the tire pressure and store the pressure in the tire pressure
monitoring system to the load you are carrying=:>

If the warning light in the instrument cluster=> page 17
illuminates and then the symbol appears in the display
=:> fig. 257 or=> fig. 258, this means the tire pressure is too
low in one or several tires (including spare tire* with sensor).
- Stop driving as soon as possible without endangering
yourself or other drivers on the road.
- Inspect the tire or tires.
- Change the tire if necessary=>
page 335.
The"' warning light in the instrument cluster comes on when the tire
is significantly underinflated.
In addition, the tire symbol { appears in the display together with
the message
Please check tire pressure=:> fig. 25 7.
After a few seconds, the message disappears again=:> fig. 258 . If you
would like to show the message again, press the

• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature .
• The yellow symbol disappears, when the tire pressure is corrected
and the new pressure is sto red in the system ~
page 330.
• After changing a wheel you have to adjust the tire pressures on all
wheels. In addition, you must then initialize the new tire pressures in
the tire pressure monitoring system~
page 330.
• If
your vehicle is equipped with a spare tire* with a wheel sensor,
the tire will be monitored and the display symbols~
page 328,
fig. 257 or~ page 328, fig. 258 will appear if the pressure is too
low .a

eye on tire pressures. B ut the driver still has the responsibility for
maintaining the correct tire pressure .•
A pplie s to v ehi cle s: w ith Tire pre ssure moni toring syst em
Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
In order for the tire pressure monitoring system to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressure, for example when the load
condition of your vehicle changes . Proceed as follows:
Corr ecting tir e pr essure
- Check the pressure in the tires (including the spare t ire*) .
- Adjust air pressure as needed in accordance with t he infor -
mation on the label located e ither on the driver's side B ­
pillar (visible when the door is open), inside the fuel filler
flap and additionally in the manual.
Saving tire p ressures
- Turn on the ignition.
- Press the [
CAR] function button .
- Select
Systems in the CAR menu .
- Select
Tire pressure mon itoring .
-Select Sto re curr. tire pressure s~ page 329, fig . 259 .
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 c urrent tire pressures and saves them as the new spec­
ified pressures .
(I] Tips
• The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B-pillar. On
Canada veh icles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap . The tire pressure
label lists the recommended cold t ire 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 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire p ressures. But the driver still has the responsib ility for
maintaining the correct tire pressure .
• If your veh icle is eq uipped w ith a standard spare ti re*, it must be
inflated to the maximum pressure specified for the vehicle .•

vated =>
page 330.
• Audi rep lacemen t pa rts were no t used .
• If snow chai ns are be ing used, system function can be compro ­
mised due to the shielding properties of the chains .
• Th e tire press ure monitor in g sys tem may not be ava ilable because
of a radio malfunction.
• Transmitters wi th the same freq uen cy, s uch as radio headphones
in the vehicle or radio equipment, can cause a temporary disrupt io n
of the sys tem throug h ex cessive elect romag net ic fie lds.
• Eliminate the interference if possible/if you can and then re-start
t he
Initialize wheels f unc tion. If the wa rning light comes on again,
you should contact your authori zed Audi dealer immediately to have
the problem corrected .
• Do not use commercially ava ilab le tire sealants . Otherw ise, the
elect rical components of the tire pressure mon itor ing system w ill no
longer work proper ly and the sensor for the t ire pressure monitoring
system will have to be replaced by a qualified workshop. •

Taking the wheel off/installing the spare
Follow these instructions step-by-step for changing the
wheel
Fig. 274 Changing a
wheel: using the
screwdriver handle
(with the blade
removed ) to turn the
bolts
Fig . 275 Changing a
wheel: alignment pin
inside the top hole
After you have loosened all wheel bolts and raised the vehicle
off the ground, remove and replace the wheel as follows:
Removing the wheel
-Use the hexagonal socket in the screwdriver handle to
completely remove the topmost wheel bolt and set it
aside on a
clean surface => fig. 274 .
- Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt hole=> fig. 275 . -
Then remove the other wheel bolts as described above.
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the spare wheel
Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts
slightly.
- Remove the alignment pin and insert and tighten the
remaining wheel bolt slightly like the rest.
- Turn the jack handle counter-clockwise to lower the
vehicle until the jack is fully released .
Use the wheel bolt wrench to tighten all wheel bolts firmly
=> page 338. Tighten them crosswise, from one bolt to
the (approximately) opposite one, to keep the wheel
centered .
(I) Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bolts .
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way~
page 341.
• The wheel bolts should be clean and easy to turn. Check for dirt
and corrosion on the mating surfaces of both the wheel and the hub.
Remove all dirt from these surfa ces before remounting the wheel. •

_______________________________________________ W __ h_a _ t_ d_o_ I_ d_o_ n_ o_w _ ? __ _
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
w ith their tread pattern pointed in the right direction .
Using a spare tire w ith a tread pattern intended for
u se in a specific direction
When using a spare tire w ith a tread pattern intended for use in a
spec ific direction, please note the fo llow ing:
• The d irect ion of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direct ion, use
t he spare t ire only temporar ily since the tire w ill no t be ab le to
achieve its optimum pe rformance character istics with rega rd to
aquap lan ing, no ise and wear.
• We recommend that you pay particular attent ion to t his fact
during wet wea ther and that you adjust you r speed to match road
conditions .
• Rep lace the flat tire w it h a new one and have it ins talled on your
vehicle as soon as poss ible to resto re the handling advantages of a
unidirectio na l tire .•
Notes on wheel changing
Please read the in forma tion => page 318, "New t ires and replacing
tires and wheels" if you are going to use a spare t ire which is different
from the tires on yo ur vehi cle.
After you change a t ire:
• Check the tire pressure on the spare immediately after installa­
tion.
• Have the wheel bolt t ightening torque checked with a torque
wren ch as soon a s possible by your authorized Audi dealer or a qua l­
i fied serv ice stat ion.
Safety first • With steel and alloy wheel rims
, the wheel bolts are correctly
tightened at a torque of 90
ft lb (120 Nm ).
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replac ed before you check
the tightening torque.
• R epla ce the flat tire with a new one and have it install ed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speed s.
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to
read the information =>
page 318, "New tires and replacing tire s
and whe els ".
• Always make sure the damaged whe el or ev en a flat tire and
the jack and tool kit are prope rly secured in the luggage compart ·
ment and are not loo se in the pa ssenger compartment.
• In an accident or sudden maneu ver they could fly forward ,
injuring anyone in the vehicle .
• Always store dam aged wheel , jack and tools secu rely in the
luggage compartment. Otherwi se, in an accident or sudden
maneuver they could fly fo rward , caus ing inju ry to passengers in
the vehicle .
• Do not u se commercially available tire sealants . Otherwi se, the
electrical component s of the tire pre ssure monitoring system * will
no longer work properly and the sensor for the t ire pressure moni ·
toring sy stem* will have to be replaced b y a qualified work shop .•
