250 Tires and wheels
Bear in mind that the tire pressure monitoring
system* can only monitor the tire pressures
you have stored . The system does not recog­
nize the load condit ion of your vehicle.
The effectiveness of the tire pressure monitor ­
ing system* will be impaired if you store nor­
mal load pressures but then operate the vehi ­
cle at its max imum load
c:> &. .
See the illustration c:> fig. 208 for the location
of the label on driver's side B-pillar (color of
the act ua l label and exact location on the ve­
hicle will vary slightly). Note
that the following table is accurate at
the time of going to press and is subject to
change. In the event of d iscrepancies, the t ire
pressure label is located on the driver's side B­
pillar always takes precedence.
The table below lists the recommended cold
t ir e inflation pressures for the Audi mode l
covered by your Owner's Literature at the vehi­
cle's capacity weight and the t ire sizes instal­
led on the respective models as orig inal
equipment, or as a factory opt ion.

The correct tire pressure for the spare wheel is
locat ed on a label on the driver's side B-pillar.
Because technical changes may be made to
ve hicl e equipment during the model year, al­
ways compa re the tire size designation on the tire
pressu re lab el on your vehicle wi th the
tires on your vehicle. Make sure that the tire
s iz e inform ation on the vehicle label is the
same as the size of the tires on the vehicle.
This is espec ially important if the vehicle be-
l ongs to someone e lse or yo u bought the ..,.

remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction 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 alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly . Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
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. 213 Display : underi nflatio n warning
Fig. 214 Display: System mal functio n
Using the ABS sensors , the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires . If the pressure decreases in one
or more tires, th is is indicated in the i nstru- ment
cluster with a warning symbol
[I] and a
message
r=> fig. 213 .
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
plac ing a tire on your vehicle
r=> page 265. 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 dr iver's side B-pillar
r=> page 249.
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

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . Thi s applies especially to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be ident ified
by the high voltage sticke r.
LE D headlights* require no ma intenance .
Please contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work ­
shop. Serious personal injury may result
from improperly performed work.
(D Tips
-If you must replace the light bulbs your­
self, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. Always read and
heed all WARNINGS
c> page 228.
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.
