188 Tire s and wheel s
forget the spare tire. 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
ga uge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
d ifference 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 veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exc eed th e maximum inflati on pres­
sure listed on th e tir e s idewall for any rea ­
s on.
Remembe r that the vehicle manufacturer, not
the t ire manufactu rer, determ ines the correct
tire pressure for the t ires on your vehicle.
It is important to check the tire pressure when
the t ires a re cold .
- Read the requ ired tire press ure from the tire
pressure label located on driver's side B-pil­
lar .
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures sho uld 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.
- Re insta ll the valve stem cap on the valve.
Wh en should I check the tir e pr essure?
The correct tire pressure is espe cially impor ­
tant at high speeds . The pressure should
therefore be checked at least once a month
and a lways before starting a journey.
When should I ad ju st the tire pressures?
Adj ust the t ire p ressu re to the load yo u are
carry ing . After changing a wheel
or replacing whee
ls you have to adjust the tire p ressures
o n all whee ls. In addition, yo u m ust then initi­
alize the new tire press ures in the t ire pres­
s u re monitoring system¢
page 199.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious pe rsonal injury
or even death.
- When the warn ing symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the handling of the vehicle and
s topping ability.
- I nco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and su dden de­
flation, ca using loss of veh icle cont ro l.
- The drive r is responsible for the co rrec t
tire pressures for all tires on the veh icle .
The applicable pressure values are loca t­
ed on a sticker on the driver's side B -pil­
lar.
- On ly when all tires on the vehicle are fil­
led to the correct pressu re, the tire pres­
sure mon itor ing system can work cor­
rectly.
- The use of incorrect tire pressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system.
- Always inf late tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tre ad separation, sudden tire failure
and loss of cont ro l.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.

quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
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 t ires 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.

204 Tires and wheels
Handling characteristics change when
dr iving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pulling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance.
A low pressure or flat
rear tire also affects
driving characteristics by pul ling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
& WARNING
Changed vehicle handling characteristics
when driving in the run -flat mode can
cause loss of vehicle contro l, a c rash and
serious personal in jury.
- Driving on special run-flat tires in the
run-flat mode will change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation .
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run-flat mode .
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
(D Note
We a lways recommend driving w ith even
more care when using these specia l tires in
the run-flat mode. Always avo id sudden
maneuvers.
Replacing run-flat tires and rims
Applies to veh icles: w it h Run -flat tires
Your vehicle was especially designed to use
special run-flat tires .
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run -flat tires . Mounting
special run-flat tires on standard whee ls will
not work and will not provide the advantages
fo the run-falt feature. Never use special run­
flat tires on standa rd whee l rims.
After dr iving w ith a t ire in the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by an author ized Audi
dealer. Tires that have been dr iven in the run­
flat mode must be rep laced .
& WARNING
=
Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode.
- Tir es that have been dr iven in the run­
flat mode must be replaced.

• Start driv ing right away so that the sealant
is distributed in the tire.
_&. WARNING
- Follow the manufacturer's safety instruc­
tions on the decal for the air pump and
the sealan t bottle.
- If a tire pressure of 1.8 bar cannot be
achieved after pumping for 5 minutes,
the tire is too severe ly damaged. Do not
continue to drive.
- Seek professional assistance if it is not
possible to repair the tire with the tire
sealant.
(D Tips
- Do not operate the electric air pump for
more than 6 minutes without stopping,

then you can pee l it off.
Final check
App lies to vehicles: wit h Tire Mobility System
After driving for a short distance, tire
pressure must be checked
• After driving for about 10 minutes, stop and
check the tire pressure .
• If tire pressure is still at least 1.3 bar, in­
flate the tire to specified pressure (see driv­
ers side B-pillar), drive to the next repa ir
shop and have the tire and the sealant bot­
tle replaced.
• If tire pressure is less than 1.3 bar, the tire
is too severely damaged. Do not continue to

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 since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb . Th is appl ies especially to the l ight bulbs
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 co rrectly taken apart and then prop­
e rly 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 bu lbs and the expertise.
Gas disc harg e la mps (X enon l ig ht s}*:
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.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed. -
Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
A WARNING
=
There are parts with sharp edges on the
openings and on the bulb holders that can
cause ser ious 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.
@ Tips
- If you must replace the light bulbs your­
self, a lways remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
¢page 165, Work­
ing in the engine compartment¢.&..
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
