Driver inf ormati on displ ay
The warning light n also illuminates in the case of a system
mal fu n ction.
The system continuously receives radio signals from sensors located inside each tire .
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 only when the tires 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 cali ­
brated, tire pressure on al l four tires and on the spare tire * should
be checked at regular intervals, adjusted if necessary and sav ed in
the proper setting (recommended pressure) =>
page 44.
The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B -pi llar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -pil lar or inside the fuel filler flap . The tire pressu re
label lists the recommended cold t ire inflat ion pressures for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
=>
page 330 .
The current temperatures and pressure of your tires can be viewed
i n the MMI =>
page 44.
& WARNING
• When the t ire pre ssure moni toring sy st em warning light i s lit ,
one or more of your tir es is s ignifi cantly under -infl ate d . Y ou s hould
s to p and che ck your tir es as soon as poss ible, and infl ate th em to
th e p rop er p ress ure as i ndicated on the vehicle's tire press ure

tion a lso is likel y to imp air t he veh icle 's handling and sto pping
ability .
• Do not adju st t ire press ure when t ire temper atu re i s excessiv e.
T hi s c ould le ad to seriou s tire dam age and even cause the ti re to
bur st, w ith the additional d ange r of an accident .
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire, includin g the sp are*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 330.
• T he tire pressure monitoring system he lps the d river to keep an
eye on tire pressures . But the dr iver st ill has the responsibility for
maintaining the correct tire pressure .
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves shou ld not be
detached or exchanged . Only the valve core needs to be replaced
and, if necessary, the va lve and the wheel electronics replaced .
• If you should put different whee ls 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 ma lfunction and a fault
message will be displayed. For more information , contact your
authorized Audi dea ler.
• Adjust the tire pressure and store the pressure in the tire pres ­
sure mon itor ing system to the load you are carrying=>

S ystem m alfun ction
If the l · warning light in the instrument cluster flashes for approxi ­
mately one minute and then remain continuously il luminated and
additional ly the
-r J ~ fig . 29 symbo l appears in the display, the
tire pressure monitoring system is not ava ilable . Th is 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 wheel sensor were
installed.
• A wheel sensor or other componen t may have failed.
• The system has detected more than 5 whe els with wheel sensors
in the vehicle, for example when carrying snow tires.
• A tire was changed but the
Initiali ze wheels function was not
activated
=:> page 45.
• Audi replacemen t 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 . • T
ransmitters with the same frequency, such as radio head­
phones in the vehicle or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields .
• Eliminate the interference i f possible/if you can and then re-start
the
I n itia lize w heel s function . If the warning light comes on again,
you shou ld contact your authorized Audi dealer immediately to have
the problem corrected .
• Do not use commercial ly availab le tire sealants . Otherwise, the
electrical components of the tire pressure monitoring system will
n o l onger work properly and the sensor for the tire p ressure moni ­
toring system wi ll have to be replaced by a qua lified workshop .•

Lane assist
Applies to veh icles : with lane assist
Description
Lane a ssist helps you keep y our vehicle in your lane .
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver. If lane assist
detects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indica tor light /: on the instrument cluster .
I f the system is in active standby mode and the turn signal is acti­
vated before driving ov er the boundary line, the warning does not
occur since the sys tem allows for intenti onal lane changes.
The system is designed for driving on freeways and expanded high ­
ways and t hus works on ly at speeds of 40 mph (65 km/h) or mo re .
& WARNING
• Lane ass ist will not k eep your vehicle in your lane. The sy stem
only warns the d riv er w hen t he vehicle i s le av ing the lan e. The
driv er is alway s re spon sible for keeping the vehicle in the lane.
• The camera is not able to d ete ct all lane boundary lines and in
s o me cases might al so dete ct lane str ucture s or objects as
boundary lines . This c an le ad to in corre ct wa rning s or warnings
that fa il to go off at all .
• The camer a's visibili ty ca n be i mpaired by vehi cle s ahe ad of

Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places on
yo ur Audi. Ins tal li n g, r em oving, s ervicing o r rep airi ng a part in an area of the vehicle can damage a part of an airbag system and
p revent that sys tem from wo rking pr operly in a c ollisi on.
Th ere are some important th ings you have to know to ma ke sure
that the effectiveness of the system will not be impai red and that
discarded co mponents do no t cause i njury or po llute the enviro n­
ment.
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly :
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never atta ch any objects su ch as cup holders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft ,
dry cloth or one moistened with plain water . Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust, or change any parts of the airbag system .
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios , etc .I must be performed by a
qualified technician who has the train ing and special equipment
necessary .
• For any work on the airbag system, we strongly recommend
that you see your author ized Audi dealer or qualified workshop .
• Never modify the front bumper or parts of the vehicle body .
• Always make sure that the side airbag can inflate without inter-
ference :
