If one of the turn signal light bulbs burn out, the turn signal will
flash twice as fast as normal. •
Electronic Stabilization Program (ESP)
The warning/indicator light monitors the electronic stabi
lization program.
The warning/indicator light has the following 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 function 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 of the ABS system.
If the ESP warning/indicator light i lluminates and stays on after you
have started the engine , this may mean that the control system has
temporari ly switched off the ESP. If this is case, you can reactivate
the ESP by switching the ignition o ff and then on again. The
warning/indicator light should go out to show that the system is
fully functional again.
If 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 process for the first few yards.
During this time, the indicator light illuminates. It goes out as soon
as the learning process is comp lete .

On-Board Diagnosti cs
Fig . 15 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your engine system
has been assigned a code. In case of a malfunction, the component
will be identified and the fault stored as a code in the control module memory .
Th e MIL lamp may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed
=> page 246.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the engine hood release lever=> fig. 15.
Your authorized Audi dealer or a qualified service station can inter
pret the code and perform the necessary repair. •
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 vehicle from going faster than the
tire speed rating. For more information=>
page 279, "New tires and
replacing tires and wheels".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (Mill will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance.
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires installed. •
Auto-Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle
features and components. It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument cluster display.
You will also hear an audible warning tone. The displays are color
coded in either red or yellow depending on their level of priority. .,_
Page 44 of 340
Driver information display
symbols appear in the instrument cluster display to alert the driver.
The warning light in the instrument cluster comes on when the
tire is significantly underinflated .
The warning light _, also lights up during a system failure.
When the wheel is turning, the system receives radio signals from
sensors located inside each tire .
A factory spare wheel is delivered with sensor. However, the spare
wheel is not checked by the tire pressure monitoring system. Such monitoring can only occur after the spare wheel has been installed
and initialized ~
page 45.
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
vehicle is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature.
In order to keep the tire pressure monitoring system properly cali
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 43.
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-pillar. On
Canada vehicles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle 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 277.
& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly under -inflated. You should
stop and check your tires as soon as possible, and inflate them to
& WARNING (continued)
the proper pressure as indicated on the vehicle's tire pressure
label
~ page 271. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-infla
tion also is likely to impair the vehicle's handling and stopping ability .
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
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 monthly when cold and set to the
recommended inflation pressure as specified on the tire pressure
table~
page 277 .
• The tire pressure monitoring system helps the driver to keep
track of the tire pressures . But the driver still 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 must not be
detached or exchanged. Only the valve core needs to be replaced
and, if necessary, the valve and the wheel electronics replaced.
• 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
dealer. .,

Power top
Normal operation
General information
The power top is designed for quick and easy operation. The power
top opens and closes automatically by itself . When the top is folded
dow n, it is stored in a special compartment and hidden under a
cover.
The power top is both wind -and waterproof under normal oper
ating conditions . Only under extreme weather conditions, for
examp le, a violent burst of rain or torrentia l rainfall, can a few drops
of water possibly form inside the roof. This is normal and no cause
for concern.
To maintain the appearance of the power roof and to keep it water
proof , read the information on roof care in=> page
233, "Power top
care". In addition to this, please note the following:
• Always open or close the power roof on ly when it is clean . Other
wise particles of dirt can scratch the rear window when the power
top fo lds down . The particles can chafe a nd damage the fabric over
a period of time. It is a lso important to remove ice and snow before
opening the power roof.
• Do not use a sharp object or any other tools, which cou ld scratch
t he fabr ic when removing ice or snow. A normal ice scraper can be
used to remove ice from the rear window.
• The power roof should be opened only when it is completely dry .
I f you open and store the power roof when it is wet, unsight ly marks
or mildew can form if left for long per iods of time .
• Never leave the roof open for severa l weeks at a time. You should
close it occasiona lly to prevent discoloration in the folds of the
fabric and to allow the creases to smooth out. This is especially
impor tan t if t he top has once been s tored away when it was not
completely dry .

Warm and cold
Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Select and set a temperature between 64 °F (+22 °C) and
86 °F (+29 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal
needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart
ment temperature as quickly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 112
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevent the windows from fogging up. When the outside temperature is high and the air is very
humid,
condensation from the evaporator may drip under the vehicle. This
is normal and does not indicate a leak.
I f the outside temperature is low, the fan normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated charcoal filter) reduces or eliminates outside air pollution (dust, or
pollen) from entering the vehicle.
The air pollutants filter must be changed at the intervals specified in your Warranty
& Maintenance booklet, so that the air conditioner
can properly work.
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
These settings will differ depending if the roof is opened or closed.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.

If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored.
& WARNING
Reduced visibility is dangerous and can cause accidents .
• For safe driving it is very important that all windows be free of
ice, snow and condensation.
• Fully familiarize yourself with the proper use and function of
the heating and ventilation system and especially how to defog
and defrost the windows.
• Never use the windshield wiper/washer system in freezing
weather until you have warmed the windshield first, using the
heating and ventilation system. The washer solution may freeze
on the windshield and reduce visibility.
0 Note
• If you suspect that the air conditioner has been damaged, switch
on ECON and contact an authorized Audi dealer to have the system
inspected.
• Repairs to the Audi air conditioner require special technical
knowledge and special tools. Contact an authorized Audi dealer for
assistance.
[ i] Tips
• Keep the air intake slots (in front of the windshield) free from ice,
snow and debris in order to maintain the proper function of the
climate control system.
• Air escapes through vents under the rear window. When placing
items of clothing on the luggage compartment cover, ensure that
the openings are not covered.
Controls and equip
ment
• If the inside temperature is very high (for example, if the vehicle
has been parked in sun), open the windows and allow the hot air to
escape before turning on the air conditioner. •
Controls
This overview will help you to familiarize yourself with the
air conditioning controls.
