• The tire pressure monitoring system helps the driver to keep an
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 .•

S ys tem malf uncti on
If the warning ligh t in the inst rument cl uste r flashes fo r approxi -
mately one minu te and then remain continuously illuminated and
additionally the => fig . 261 symbol appears in the d is p lay , the
tire pressure monito ring system is not available . This can have various
causes.
Vehicle OP-eration
• If the message appears at the end of the learning process, the
system c annot recognize the whee ls ins talled o n the veh icle . T his can
be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed .
• T he sy stem has detected more than S whee ls wi th whee l sensors
i n the ve hicle, for example when carry ing snow tires.
• A tire was changed but the
Init ialize wheel s function was not acti­
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. •

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
