remain continuous ly illuminated . This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signa l low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea­
sons, including the installat ion of replace­
ment or alternate tires or wheels on the veh i­
cle that prevent the TPMS from funct io ni ng
properly. Always check the TPMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies 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.
F ig. 1 47 Disp lay : under infla tion warn ing
Using the ABS sensors, the tire pressure moni ­
toring system compares the t ire tread circum­
fe rence and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indicated in the instru­
ment clus ter with a warning symbol
RE and a
message
'* fig. 147. The dr iver message in the
d isp lay goes out after 5 seconds. The driver
message can be d isplayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on ­
ly one tire is affected, the display will indicate
its pos ition.
The ti re pressure monito ring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti-
Tire s an d wheel s 215
al and fu ll load pressure) or after changing o r
replacing a tire on your vehicle '*
page 216.
The TPMS indicator on ly mon itors the t ire
pressure that you have previously stored . You
can f ind the recommended tire pressures for
your vehicle on the label on the driver's door
pillar ¢
page 200.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure

Handling characteristics change when
driving 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 pu lling 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 character istics by pulling 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.
A WARNING
Changed vehicle handling character istics
when driving in the run -f lat mode can
cause loss of vehicle contro l, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-f lat mode wi ll 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.
Q) Note
We always recommend driving w ith even
more care when using these special t ires in
the run-flat mode . Always avo id sudden
maneuvers.
Tires and wheels 219
Replacing run-flat tires and rims
App lies to veh icles : w it h Run -flat t ires
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 wheels will not work and w ill not prov ide the advantages
fo the ru n-falt feature . Never use spec ial run­
flat tires on standa rd wheel rims.
After dr iving with a tire i n the run-flat mode,
always have the vehicle and affected tire(s)
and rim(s) inspected by a n authorized Audi
dealer. Tires that have been driven in the run­
f lat mode must be rep laced .
A 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 .
- Tires that have been dr iven in the run­
flat mode must be replaced.

226 What do I do now ?
-Position the vehicle jack only at the
designated lifting points and align the
jack. Otherwise, the vehicle jack could slip and cause an injury if it does not
have sufficient ho ld on the vehicle.
- A soft or unstab le surface under the
jack may cause the vehicle to slip off the jack. Always prov ide a firm base for
the jack on the ground.
If necessary,
use a sturdy board un der the ja ck .
- On hard, slippery surfac e (such as tiles)
use a rubber mat o r similar to prevent
the j ack fr om s lipp ing.
- T o he lp p revent injury to yoursel f and
yo ur passenge rs:
- Do not raise the vehicle unti l yo u are
sure the jack is sec urely engaged.
- Passenge rs must not rema in in the ve­
h icle when it is jac ked up .
- Make sure that passen gers wait in a
safe p lace away from the vehicle and
well away from the roadway and traffic.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authori zed 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
reac h 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
e rly put back together to help p revent 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 author ized Audi dealer replace any bu lbs
for you, since your dealer has the p roper tools,
the correct b ulbs and the expertise.
Ga s di sc harg e lamp s (Xeno n light 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
t he 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.
Fu ses and bulb s 231
-Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualif ied 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 serious c uts.
- If you are uncertain about what to do,
have the work performed by an a uthor­
ized Audi dealer or othe r qualified work­
shop. Ser ious personal in ju ry may result
from imprope rly performed work.
(D Tips
- If you must replace the light bulbs your­
self, a lways remember that the eng ine
c ompartment of any vehi cle is a hazard­
ous area to work in. A lways read and
heed all WARN INGS
~page 174, Engine
compartment ¢&, .
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
