About this Owner's Manual
This manual contains important information,
tips, suggestions and warnings for using your ve­ h icle.
Keep th is manual in your veh icle at all times. Th is
is especially important if you loan your vehicle to
others or sell it.
This owner's manua l describes the
equipment
range
specified for this mode l at the tim e of
printing. Individua l equipment options described
may only be available at a later date or may only
be offered in certain countries.
Some sect ions in this manua l do not apply to all
vehicles. When this is the case, the beginning of
the section indicates the
validity, for example
"Applies to vehicles: with auxiliary heating". Op­
tional or vehicle-specific equipment is a lso identi ­
fied with an asterisk"*".
The
illustrations are designed as a general guide
and on your vehicle may look slight ly different
than what is illustrated.
There is a
Table of Contents at the beginning of
this owner's manua l that lists all of the topics
covered in this book in the order that they ap­
pear. There is also an alphabetical

Instruments and indicator lights
reached the reserve mark, the bottom LED will
turn red and the
ljJ indicator light turns on
¢
page 23. The bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level¢
page 28, On-board comput­
er display.
For the tank capacity in your vehicle, refer to the
Technical Data
¢ page 260.
(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
tor, an indicator light. will turn on when the
coolant temperature is too high ¢
page 19. Re­
fer to ¢(1) .
The coolant temperature indicator @c:>
page 10,
fig . 3 only works when the ignition is switched
on . To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full accel­
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
This is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
12
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
c:> page 19 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area . Stop the engine and al­
low it to cool before working in the engine
compartment. Always follow the informa­
tion found in ¢
page 198, Working in the
engine compartment.
(D Note
- In vehicles with a boost pressure indicator* ,
this indicator replaces the temperature dis­
play. To promote a long engine service life,
avoiding high engine speeds, full accelera­
tion and heavy engine loads during approxi­
mately the first 15 minutes when the en­
gine is cold is recommended . The amount of
time until the engine is warm depends on
the outside temperature . Check the engine
oil temperature* if necessary .
c:> page 30
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy engine
load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.

tion reduces automatically and eventually
turns off as br ightness outside decreases.
This function reminds the driver to turn the
headlights on at the appropriate time .

functio n*
To help you see the curb when backing into a

slight ly. For this to happen, the knob must be in
the position for the front passenger's outside
mirror .
You can adjust the tilted mirror surface by turn·

When you lock the vehicle, the mirrors fold in.
When you start the ignition, the mirrors fold out.
A WARNING -,.
Curved m irror surfaces (convex) enlarge the

Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and removes
humidity from the air in the vehic le interior. It is
the most effective when the windows and panor­
ama sunroof* are closed.
If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process . For this reason, the
windows and panorama sunroof can be opened
from the outside .~
page 41, Convenience open­
ing/closing
Pollutant filter
The pollutan t filter removes pollutants such as
dust and pollen from the air.
Key recognition
You can store various settings for the manua l and
automatic
climate control system* and assign
them to the key being used .
A WARNING
Poor visibility can lead to acc idents.
- For safer driving, keep all w indows free of
ice, snow and fog.
- Become familiar as quickly as possible with
the correct use and function of the climate
control system, espec ially with the defrost­
ing and defogging function .
- When the temperature is below freezing,
only use the windsh ield washer system after
the windsh ield has been warmed by the cli -
64
mate control system. The washer f luid could
freeze on the w indshield and impair visibili­
ty.
(D Note
- If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility .
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an author ized Audi dealer
or authorized Audi Service Facility .
@ For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
a ir .
@ Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogg ing over, the air intake in
front of the w indshield must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
dr ip and form a pudd le of water under the
vehicle . This is normal and does not mean
there is a leak .
- Th e energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- The f lows through the vents under the rear
window. Make sure the openings are not
covered when p lacing clothing on the lug­
gage compartment cover.

sepa rately .
Manual climate control system*
For a comfortable temperature, we recommend:
- in warmer time s of the year, set the tempera-
ture so that it is only a few degrees below the outside temperature .
- set the blower at a moderate speed
- don't direct the air flow d irectly on the passen-
gers
IA/C l Switching the cooling mode* on and off
The cooling mode only functions with the blower
turned on . The air is not coo led and humidity is
not removed when cooling mode is switched off .
This can cause fog on the windows. The cooling
mode switches off automat ically when there are
cold outside temperatures.
~ Adjusting the blower
To prevent the windows from fogging over, the b lower should a lways run at a low speed. When
t he w indows are fogged, we recommend using a
higher blower speed and turning the knob to~-

To avoid damage to the heating elements in the seats, do not kneel on the seats or place
heavy loads on a small area of the seat.
(D Tips
- The setting for the seat heating on the driv­
er's side is assigned to the key that is in use.
- If the front passenger's seat heating is
turned on, it will not turn on again automat­
ically if more than 10 minutes have passed
between switching the ignition
