Safety belts i
This warning/indicator light reminds y ou to put on your
safety belt.
The .ft warning/indicator light i lluminates when the ignition is
switched on to remind the driver and (on USA mode ls only) any front
passenger to put on the safety belt. Additiona lly, an acoustic
warn ing (gong) w ill also sound.
For more
information~ page 176 , "Safety belt warning light 4". •
Turn signals ¢ ¢
The in dicator light flashes when you use either turn
signal.
Whenever you use the left ¢ or the right ¢ turn signal, the indicator
l ight flashes. W hen you use the emerge ncy flasher, both indicator
lights f lash .
I f one of the turn signal light bulbs burn out, the turn signal will
flash twice as fast as normal. •
Electronic Stabilization Program (ESP) fJ
The warning/indicator ligh t monit ors the electr onic s tabi ­
lization program.
The ~ warning/indicator light has the fol lowing functions:
• it flashes while you are driving, when the ESP is working .
• it illuminates when you switch on the ignition for approximately
2 seconds as a funct ion check.
• it illuminates when there is a ma lfunction in the ESP.
• it illuminates after the battery has been disconnected .
• it illuminates continuous ly when the ESP is switched off . •
it illuminates if there is a malfunction in the ABS, since the ESP
is part o f the ABS system.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporar ily switched o ff the ESP . If this is case, you can reactivate
the ESP by switching the ignition off and then on again . The
warning/indicator light should go out to show that the system is
ful ly functional again .
I f the battery terminals were disconnected and re -connected, the
vehic le was jump started or the battery is very weak, the ESP sensor
system goes through a learning p rocess for the firs t few yards.
D uring th is time, t he ind icator l ight i llu minates. It goes out as soo n
as the learning process is comp lete.
For more information about the
ESP ~ page 236. •
Generator 0
T his warning/indicator light detects a malfunction in the
generator or i n t he vehicle's elec trical system.
T he O warning/indicator light i lluminates w hen you switch on the
ignition and must go out after the engine has started .
I f the
O warni ng/ind icator light illum inates while you a re driv ing,
you shou ld contact your authorized Audi dealer . Since the vehicle
battery is dischargi ng, you should sw itch off any unnecessary elec ­
trical consumers (for example, the air conditioner) .

Driver inf orma tion di spl ay
Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h}. This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive speeds, your vehicle also has an electronic speed limiter . The elec ­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating. For more
information~ page 305, "New tires and
r eplacing tires and wheels" .
If the vehicle approaches the tire speed rating, the engine control
unit wi ll turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine control unit receives faulty vehicle road speed signals,
t he Malfunc tion Indicator Light (MIU will illuminate. If this occurs,
contact the nearest authorized Audi dea ler for ass istance.
&_ WARNING
Al wa ys o bserve th e pos te d speed l imit s and adjust your sp eed t o

C o nt rol: a ll syste ms
c h eck ed OK
Whenever the ignition is turned on, Auto -Check Control checks the
proper functioning of important vehicle components and systems.
Auto -Check Contro l keeps up its continuous monitoring of vehic le
systems even as you are driving.
If Auto Check senses an irregular condition or a malfunction
requiring urgent repair, it generates a specific symbol or short
message in the instrument cluster center display . You will also hear
an audible warning tone . The disp lays a re color coded in either red
or yellow depending on their level of priority.
A red symbol means
D anger , a yellow symbol indicates Warning .
Along with some particular red symbols, a message will appear in
the display to alert the driver to certain conditions. •

Battery voltage low .::::3
If the symbol illuminates, contact your authorized Audi dealer
and have the following components inspected:
• drive belt
• generator
• battery charge
Also see if the generator warning/indicator light illuminates
=> page 22. •
Defective light bulb warning ~
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol wi th a message appears in the display to
tell you which bulb is burnt out and where it is located . For example :
REAR LEFT TURN SIGNAL
After 5 seconds, the message d isappears . If you want to reca ll the
message into the display, press the CHECK button.
There are three reasons why the defective bulb message wou ld
appear in the display:
• the light bulb has burnt
out => page 328.
• the fuse is "blown"=> page 326, "Replacing a fuse" .
• the wire connec tion to the light bulb is defective .
Have the bulb replaced or the connection repaired by your autho­
rized Audi Service department .

• Each tire should be checked month ly when cold and inflated to
the infla tion pressure recommended by the vehic le manufacturer
on the vehicle placard , tire inflation pressure label, or in chapter
=> page 297 . (If your ve hicle has tires o f a different size than t he size
indicated on the vehicle placard or tire inf lation pressure label, you
should de termine the proper tire inflation pressure for those
tires.) •

TPMS malfunction indicator
Your vehic le has also been equipped with a TPMS ma lfunction indi ­
cator to indicate when the system is not operating properly. The
TPMS ma lfunct ion indicator is combined with the low tire pressure
telltale . When the system detects a ma lfunction, t he tellta le wi ll

When the ma lfunc tion ind icator is ill uminated, 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 o f rep lacement or a lternate tires or wheels on the
vehic le that prevent the TPMS from functioning properly . A lways
check t he TPMS malfunction tellta le after replac ing one or more
tires or whee ls on your v ehicle to ensur e that the replacement or

Introduction
T he tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire pressure monito ring system se nses a significant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument clus ter disp lay to a lert the driver.
The
(l) warning light in the instrument cluster comes on when the
t ire is significa ntly under inflated.
The warning light
(l) also lights up during a system failure .
When the whee l is turning, the system receives radio signals from
sensors located inside each tire.
A factory spare wheel is delivered with sensor . However, the spare
whee l is not checked by the ti re pressure monitoring sys tem. Such
monitoring can on ly occur after the spare wheel has been insta lled
and
initia lized => page 50.
Be aware that t ire pressure is a lso dependent o n the temperature of
the tire . For every 18 °F (1
O °C) increase in tire temperature, tire pres ­
su re increases by about 1.5 psi (0 .1 barl. The tire warms up wh ile the
vehic le is moving and t ire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature .
I n order to keep the tire pressure moni toring system prope rly ca li­
brated, tire pressure on all four tires shou ld be checked at regular
intervals, adjusted if necessary and saved in the proper sett ing
(reco mmended
pressure) => page 48.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure label is located on the dr iver's side B -pillar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -p illar o r inside the fue l fi ller flap. The tire pressure
label l ists the recommended cold tire inflation pressures for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the t ime it was manu factured . For recommended tire
