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-

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

274 What do I do now ?
-Passengers must not rema in in the ve
h icle when it is jacked up.
- Make sure that passengers wait in a
safe p lace away from the vehicle and
well away from the road and traffic.
- Make sure jack position is correct, ad
just as necessary and then continue to
raise the jack.
- Changes in temperature or load can af
fect the height of the vehicle.
CD Note
D o not lift t he vehicle by the si ll. Position
the vehicle jack only at the designated lift
ing points on the sill. Otherwise, your vehi
cle will be damaged.
@ Tips
The vehicle jack mode switches off auto mat ica lly at speeds above
10 km/h.
Taking the wheel off/installing the spare
Follow these instructions step-by-step for
changing the wheel.

After yo u have loosened all wheel bo lts and
raised the vehicle off the ground, remove and
replace the wheel as follows:
Removing the wheel
.,. Use the hexagonal soc ket in the scr ewdriv
er handle
to completely remove the top
most whee l bolt and se t it aside on a
clean
surface r=> fig. 228 .
.,. Screw the threaded end of the alignme nt
pin from the tool kit hand-t ight into th e
empty bolt hole
Q fig. 229 .
.,. Then remove the other whee l bolts as de
scribed above.
.,. Take off the whee l leaving the a lignment pin
in the bo lt ho le r=> 0 .
Putting on the spare wheel
.,. Lift the spare whee l and carefully s lide it
over the alignment p in to g uide it in place
Q0 .
.,. Use the hexagona l socket in th e screwdriver
ha ndle to screw in and tig hten all whee l
bolts
slightly.
.,. Remove the al ignment pin and insert and
tighten the remain ing wheel bolt slightly
like the rest .
.,. Turn the jack hand le counter-clockwise to
lower the vehicle until the jack is fully re
leased .
.,. Use the wheel bo lt wrench to tighten all
wheel bo lts fi rm ly
r=> page 271 . Tighten
them
crosswise, from o ne bolt to the (ap
p rox ima tely) opposi te one, to keep the
wheel ce nte red .
CD Note
When remov ing or i nsta lling the whee l,
the rim could hit t he b ra ke ro to r and d am
age the ro tor. Wor k caref ully and have a
seco nd person hel p you.
(D Tips
Never use the hexagon al socke t in the han

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.

perform these operations.
Starting by pushing or
towing
(D Note
Ve hicles w ith an au tomatic tra nsmission
cannot be started by pus hing o r tow ing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi
cle.
If the engine shou ld fail to start because of a
discha rged o r wea k battery, the battery can be
connected to the battery o f
another vehicle,
using a
pair of jumper cables to start the en

Jumper cables
Use only jumper cables of sufficiently la rge
c ross section to carry the starter c urrent safe
