reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous 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 illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installa tio n of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ion ing
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.
If the Tire Pressure Monitoring System
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 .
Fig . 177 In strum ent clus te r: indica tor l igh t w ith mes ­
sage
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 changes in one

or more tires, this is indicated in the instru­
ment cluster disp lay with an indicator light
ti] and a message c:::> fig . 177. If only one tire
is affected, the locat ion of that tire will be in­
dicated. The message turns off after a few mi­
nutes . You can d isplay the message aga in
c:::> page 2 8 .
The tire pressures must be stored in the menu
display again each time the pressures change
(sw itching between partial and full load pres ­
sure) or after chang ing or replacing a t ire on
your vehicle

monitori ng system only monito rs the tire
pressure yo u have stored . Yo u can find the rec ­
ommended t ire press ures for your vehicle on

Tire t read circumference and vib rat ion charac­
teristics can change and cause a tire pressu re
warning if :
- I f the tire pressure in one or mo re tires is
t oo low,
- the t ire has structural damage,
-The tire was replaced or the t ire p ressure
changed and it was not stored again

& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re labe l on the veh icle
<:?page 235. Driving with a t ire with low
pressure causes the tire to overheat and
can res ult in failure of the tire . Low pres ­
sure can a lso have a negat ive effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be de layed .
- Ask your author ized dealer if r un-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the ident ificat ion "AO" or
"RO" ¢ page 248 have been matched
with your A udi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
on ly mon itor the t ire pressure of the
driving tires . Check the tire pressu re of
the spa re wheel in the luggage com part­
ment so tha t if ne cessary i t is ready for
u se.

Storing tire pressures
Applies to vehicles: wit h tire press ure mo nitor ing system
A change in tire pressure or a change in tires
must be stored in the system.
The tire pressure is stored in the MMI.
.. Ma ke s ure before storing that the ti re pres ­
sures of a ll four tires meet the specified va l­
ues and are adapted to the load. Otherwise
the system could malfunction
¢ page 235.
.. Switch t he ignit ion on.
.. Select: the

(D Tips
Do not store the tire pressures if snow
cha ins a re i nstalled. O therw ise the system
could m alfun ction.

264 What do I do now?
-Always store the vehicle tool kit, the jack
and the replaced tir e in the luggage com­
partment ¢

Changing a wheel
When you change o wheel, follow these­
quence described below step-by-step and in
exactly that order .
1. Remove the decorative wheel cover*. For
more details see also¢
page 264, Deco­
rative wheel covers
or ¢ page 265,
Wheels with wheel bolt caps.
2 . Loosen the wheel bolts¢ page 265 .
3. Locate the proper mount ing point for the
jack and align the jack below that point
¢page 266.
4. Raise the car with the jack ¢ page 266.
5. Remove the
wheel with the flat tire and
then install
the spare ¢ page 267.
6. Tighten all wheel bolts lightly.
7 .
Lowe r the vehicle with the jack.
8 . Use the wheel bolt wrench and
firmly
tighten all whee l bolts c::> page 265.
9. Replace the decorative wheel cover*.
A WARNING
Always read and follow all WARNINGS and
information
c::> .&. in Raising the vehicle on
page
266 and c::> page 268.
After changing a wheel
A wheel change is not complete without the
doing the following .
• Always store the vehicle tool kit, the jack*
and the replaced tir e in the luggage com­
partment ~
page 132 .
• Check the tire pressure on the spare wheel
i mmediately after mount ing it.
• As soon as possible, have the
tightening
torques
on a ll wheel bo lts checked with a
torque wrench. The correct tightening tor­
que is 90 ft lb (120 Nm).
• Have the flat tire
replaced as soon as poss i­
ble.
(D Tips
- If you notice that the wheel bolts a re
corroded and difficult to turn while
chang ing a tire, they should be rep laced
before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
- After changing a whee l, the tire pressure
in all four tires must be checked/correct­
ed and the tire pressure monitoring indi­
cator must be stored in the MMI
c::>page260.
