214 Tire s and wheel s
When the malfunction indicator is illuminat­
ed, the system may not be able to det ect or
signal low t ire pressure as intended . TPMS
malfunct ions m ay occur for a variety of re a­
sons, including the installa tion of replace­
ment or a lternate tires or wheels on the vehi ­
cle that prevent the TPMS from funct ioning
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 monito ring 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. 157 Display : under inflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster w ith a warning symbo l
RE and a
message¢
fig. 157 . If on ly one ti re is affect ­
ed, the location of that tire will be indicated .
The t ire p ressu re monito ring system must be
reset each t ime the press ures a re adjusted (e.
g . when switching between partia l and full
l oad pressure) or after changing or replacing a
tire on your vehicle ¢
page 215. The TPMS in­
dicator only monitors the tire p ressu re that
you have previously s tored. You can find the
recommended tire pressures for your vehicle
on the label on dr iver 's side B -pillar

-The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your authorized dealer if run-flat
tires may be used on your vehicle. Your
vehicle registration becomes invalid if
you use these tires when not permitted .
Damage to your vehicle or accidents
could also result.
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identification on the
tire sidewall
¢page 206. We recom ­
mend using these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monit oring sys te m
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset.
"'Before storing the new tire pressures, check
that the current pressures on all four tires correspond to the specified values and
adapt the pressures to the current load

A WARNING 1=
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed with the fold­
ing chocks or other objects. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving .
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
¢ page 100.
(D Note
If you are changing the wheel on a steep
incline, use the folding chock¢
page 217
to block the opposite wheel to prevent the
vehicle from moving.

c::>fig. 165 .
There is exactly one locat ion for each wheel.
The jack must not be positioned at any other
location
c::> .&. c::> (D .
Soft g round under the jack can cause the ve­
hicle to slip off the jack. A lways p lace the jack
on firm ground. Use a f lat, stable support if
necessary. Use a non-slip surface such as a
rubber mat o n a
slippery surface such as tile.
A WARNING
- You or your passengers co uld be inju red
while changing a wheel if you do not fo l­
low these safety p re ca utions:

j ack. Otherw ise, the vehicle jack could
slip and cause an injury if it does not
have sufficient hold on the vehicle.
- Use only the jack* supplied with your
vehicle to raise the veh icle . If you use a
j ac k from a different veh icle, you r vehi­
cle may slip off the jac k -ris k of injury !
- Do not use the jack* supplied with yo ur
vehicle to raise other vehicles, as these
may s lip off the jack -risk of injury!
- A soft o r unstable surface unde r the
j ac k m ay cause the veh icle to slip off
the jack . Always prov ide a fi rm base for
the jack o n the ground.
If necess ary,
u se a st urdy board under the jack.
- On hard, sl ippery su rface (such as t iles)

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increas ingly more and more
difficult to replace vehicle lig ht bulbs s ince 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 meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correct ly taken apart and then properly put
back together to he lp prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper­
ly resealed.
For your safety, we recommend that you have
your authori zed Audi dea ler 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 e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light are identified by
the high voltage st icker.
A WARNING "--
Changing Xenon lamps without the neces-
sary equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening inju­
ries can result from improper handling of
the high-voltage portions of such lamps!
- Only your authorized Audi dealer or qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts 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 authorized Audi dealer or qualified
workshop. Serious personal injury may
result from improperly performed work.
@ Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine ..,.
