telltale. When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the t ire pressure monitoring system senses a s ignificant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument cluster display to a lert the driver.
The warning light in the instrument c luster comes on when the
tire is significantly underinflated
=> page 17.
The warning light
malfunction . also
illuminates in the case of a system
Be aware that tire pressure is also dependent on the temperature of
the tire . For every 18 °F (10 °C) increase in tire temperature, tire pres
sure increases by about 1 .5 psi (0. 1 bar) . The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure on ly when they are
cold , when the temperature of the tires
is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly ca li
brated, tire pressure on all four tires should be checked at regular intervals, adjusted if necessary and saved in the proper setting
(recommended
pressure)=>
page 44.
The tire pressure is shown on the label located on the driver 's side
B -pillar (visible when the door is open) .
& WARNING
• When the tire pre ssure monitor ing system warn ing light i s lit ,
one or more of your t ir es is s ignificantl y unde r-inflated . You should
s top and check your tire s as s oon as po ssible , and inflate them to
the p rope r pre ss ure as indi cated on th e vehicl e's tire pr essure
label
=> pag e 242. Driv ing on a s ignific antl y un der-inflated t ire
c a use s the tire to overhe at and can le ad to tire fa ilure. Unde r-inf la
ti on also i s lik el y to impair the vehicle' s handling and stopping
ability .
• Do not adju st t ir e pressur e wh en t ire t emp erature is exce ssiv e.
Thi s could le ad to seriou s tire dam age and even cau se the tire t o
bur st, w ith the addition al dan ger of an accident.
W For the sake of the environment
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire should be checked month ly when the temperature of
the tires is abou t the same as ambient air temperature and s et to the
recommended inflation pressure as specified on the tire pressure
label =>
page 242.
• The factory supplied spare whee l is equipped with a se nsor for
the tire pressure monitoring sys tem. As long as the spare wheel is
n ot mounted, the tire pressure of this tire wil l not be monitored.
• T he tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver still has the responsibility f or
maintaining the correct tire pressure . .,_
Page 45 of 316

• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambien t air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged. The valve core, nut, valve sea ling and sea l washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be rep laced .
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dea ler.
• Adjust the tire pressure and store the pressure in the tire pres
sure monitoring system to the load you are carrying .•
Significant loss of air pressure \-,1
The yellow symbol appears in the event of a significant
loss of air pressure.

[ i ] Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after
wards=> page 44.
• Tire pressure must only be adjusted when the temperature of the
t ires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=>
page 44.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on a ll wheels. In add ition , you
must then initia lize the new tire pressures in the tire pressure moni
toring system =>

Storing tire pressures
Correct storage of specified pressure is the basic require
ment for reliable tire pressure monitoring.
F ig . 29 S ET -butt on:
T ire pressure mon i
t or ing syste m
In order for the tire pressure monitori ng system to operate
appropr iately, you have to re-save the specified p ressures
whenever you adjust tire pressures, for example when the load co nd ition of your vehicle changes. Proceed as fo llows:
Corr ecting tir e pr es sure
Check the pressure in the t ires.
- Adjust air pressure as needed to comply w ith the infor
mat ion on the label located on the driver's side B -pillar
(visible when the door is open) .
Saving tire pressures
-Turn on the igniti on.
- Press the button :::> fig. 29 for app rox imately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three t imes .
All pressure warning indicators in the d isplay will be canceled. Following each intentional change in specified pressures, ti
re pres
sures must be resaved.
After the pressures are saved, the tire pressure monito ring system
measures the current tire pressures and saves them as the new
spec ified pressures .
[ i ] Tip s
• The tire pressure is shown on the tire pressure labe l. The tire
pressur e lab el is located on the driv er's sid e B-pillar (visible when
the door is open). The tire pressure label l ists the recommended
cold tir e inflation pr essur es for the vehic le at its maximum capacity
weigh t and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for norma l load
conditions, please see chapter~
page 242.
• The tire pressure monitoring syst em he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the cor rect tire pressure .•

A malfunction can have various causes.
Fig. 30 Display:
System malfunction
If the t warning light in the instrument cluster flashes for approxi
mately one minute and then remains continuously illuminated and
additionally the
r fin'-=> fig. 30 symbo l appears in the display, the
tire pressure monitoring system is not available. This can have
various causes .
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
installed.
• A wheel sensor or other component may have failed .
• During initia lization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system.

ment
Driver inform ation system
• A wheel change was made but the button => page 44, fig. 29 was
not pressed .
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio malfunction.
• Transmitters with the same frequency, such as radio head
phones in the vehic le or radio equipment, can cause a temporary
disruption of the system through excessive e lectromagnetic fields.
• Eliminate the interference if possible/if you can and then
proceed as follows: Turn off the engine for 20 minutes . Then drive
another 10 min. If the warning light comes on again, you should
contact your authorized Audi dealer immediately to have the
problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni
toring system will have to be replaced by a qualified workshop. •

Clear vision
Coming home situation
In
darkness, the activated system will turn on the headlights, side
marker lights , rear side marker lights , tail lights, and rear license
plate light as soon as the driver's door is opened from inside.
As long as one of the doors or the rear lid remains open, the set of
external lights will keep burning for about four minutes maximum.
To provide light for departure, the set of vehicle lights will keep
burning for about another 30 seconds after all doors and the rear lid
have been closed.
The factory-set time of 30 seconds until the lights are switched off can be adjusted if you prefer a longer or shorter duration. Have the
adjustment done by your authorized Audi dealer or a qualified work
shop. The system can be adjusted to keep the lights burning for a
maximum of 60 seconds.
Leaving home situation
As soon as the vehicle is unlocked by pressing the
ti button on your
remot e control, the set of external l ights is switched on .
The external lights are switched off as soon as the driver's door is
opened from outside . Even if you had the system readjusted to keep
the lights burning for an extended time for coming home, the
external lights will be turned off if you do not open the driver's door
within 60 seconds after unlocking. See chapter "Opening and
Closing" in your Owner's Manual. If the lights are switched off
before you reach the driver's door, press the
a button once more to
turn them on again.
[ i] Tips
• Do not attach any stickers to the windshield in front of the two
light sensors, as this would interfere with both the automatic oper
ation of the headlights and the automatic dimming of the inside
mirror(s). • If
the vehicle is remotely unlocked and locked three times in
succession, leaving home will not turn on the lights a fourth time to
safeguard the battery and lights.
• If you wish to use the coming home/leaving home function regu
larly, you can leave it activated at all times without risking perma
nent strain on the electrical system. As the system is controlled by
light sensors, it will only be energized in darkness .
• Frequent use of the coming home/leaving home function for
approaching and departing a vehicle parked in the dark will strain
the battery. This applies particularly if only short distances are
driven between stops . Occasionally drive longer distances to make
sure the battery is recharged sufficiently.
• If the fog lights have been switched on by the coming
home/leaving home function, they will always be switched off when
you switch on the ignition. •
