Tire pressure monitoring system
UJ General notes
Applies to vehicles: with tire pressure monito ring system
Each t ire, i ncluding the spare (if provi ded),
should be chec ked month ly w hen cold and in
flated to the inflation pressure recommended by the vehicle manufacture r o n the vehicle
placar d or tire infla tion pressure label. (If your
veh icle has t ires of a diff erent siz e than the
size ind icat ed on the vehicle p lacard or tir e in
flation pressure label, you should deter mine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
pr essu re tellta le when one or mo re of your
tires is significantly under -inflated . Accord ing
l y, when the low tire p ress ure telltale illumi
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driv ing on a signif icantly un
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under -inflation al
so reduces fuel efficiency and tire t read life,
and may affect the ve hicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for p roper t ire mainte nance , and it is the dr iv
e r's responsib ility to ma inta in cor re ct t ire
p ress ure, even if under- infla tion has no t
reached the leve l to trigger ill umin ation of the
TPMS low tire pressure telltale.
Your veh icle has also bee n equ ipped with a
TPMS malfunc tion indica to r to indica te when
the system is not opera ting properly. The
TPMS mal function indicato r is combined wi th
the low tire press ure tellta le . When the sys
tem detects a malf unct ion, the te lltale will
flash for approximately one minute and then remain cont inuo usly illuminated. This se
quence will continue upon subsequent vehicle
start-ups as long as the ma lf u nction ex ists .

When the malfunction indicator is illum inat
ed , the system may not be ab le to detect or
s ignal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea
sons, including the insta llation of replace
ment or alternate tires or wheels on the vehi
cle that p revent the TPMS from functioning
proper ly. Always check the TPMS malfunction
te lltale after rep laci ng one or more tires o r
whee ls on you r vehicle to e nsur e th at the re
placement or alterna te t ires and wheels a llow
the TPMS to continue to func tion p roperly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indica tor in the instrument
cluster informs you if the tire pressure is too
Low or if there is a system malfunction.

A WARNING
- If the tire pressure indicator appears in
the instrument cl uster display, one or
more of your tires is significantly under
inflated. Reduce your speed immediately
and avoid any hard stee ring or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In
flate the tire pres sure to the proper p res
s u re as in dic ated on the vehicle 's t ire
pressure label ¢
page 238. Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor
ty driving style, winter conditions or un paved roads), the pressure monitor indi
cato r may be delayed .
-Ask your authorized Aud i dea ler if run
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with
t he "AO" or "R O" ident ifi cat ion on the
tire s idewa ll
c> page 246 . We recom
mend using these tires.
Reset tire pressure monitoring system
Appl ies to vehicles: wit h tire p ressu re mo nito rin g system
If the tire pressure is adjusted, wheels are ro
tated or changed, the TPMS must be reset via
radio or MMI*.
.. Before resett ing the TPMS, the current pres
sures of a ll four tires must correspond to
the specified values . Ad just the tire p ressu re
and reset the pressure in the tire pressure
mon ito ring system according to the load
