the time it was manufactured . For the

page 253, fig . 204.
Most tires lose air naturally over time. They
can also lose some air if you drive ove r a pot­
hole or hit a curb while parking . It is usually
not possible to see whether the radial tires
used today are under inflated just by looking
at them.
Therefore, be sure to check tire pressures at
least once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See~
page 257, Tires and vehicle
load limits
for more important information.
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures. Check all of the tires and be sure not to
forget the spare t ire. If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the
l oad (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you plan to do .
Never exceed the maximum inflation pres­
sure listed on the tire sidewall for any rea­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determ ines the correct
tire pressure for the tires on your vehicle.
It is important to check the tire pressure when
the tires are cold.
- Read the req uired ti re pressure from the tire
pressure label. The tire pressure label is lo ­
cated on the driver's side B-pi llar . -
Tu rn the va lve stem cap counter -clockwise
to remove it from the tire va lve .
- Place the air pressure gauge on the va lve.
- The tire pressu res should only be checked
and adjusted when the tires are cold. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the valve.
When should I check the tire pressure?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before starting a jour ney. Do not
f orget to check the tire pressure for the spare
whee l
~page 272.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
carrying. After changing a wheel
or replacing
whee ls you have to adjust the tire pressures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres­
sure monitoring system*~
page 267.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
Rt] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping abi lity.
- Incorrect tire pressures and/or underin­
flation can also lead to su dden t ire fail­
ure, including a blowout and sudden de­
flation, causing loss of veh icle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle.
The applicable pressure values are locat­ ed on a sticker on the driver's side B-pil-

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

¢ fig. 210 and the indica­
tor light
ltJ in the instrument cluster blinks
for approximate ly one minute and then stays
on, there is a system malfunction .

¢
page 269. If the indicator light does not
turn off or if it turns on short ly thereafter, im­
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

Bulbs
Replacing light bulbs
For your safety, we recommend that you hav e
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more
difficu lt to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb . This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious 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 .
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker .
LED headlights* requ ire no ma intenance .
Please contact your authori zed Audi dealer if a
bulb needs to be replaced.
Fuses and bulbs
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
plode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qua lified 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 inj ury may result
from improperly performed work.
(D Tips
-If you must replace the light bulbs your­
sel f, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
<=> page 226, Engine
compartment<=> ,&..
- It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.
