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.

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.

Towing a trailer makes the engine work harder . It
is important tha t the cooling system 's pe rform­
ance is up to the additional load. Make s ure that
the coo ling system has enoug h flu id.
Tire pressure
When towing a trailer, inflate the tires of your ve-
hicle to the cold tire pressure listed under "Full

-Drain th e oi l into a container desi gned for
this purpose, one large enough to ho ld at
least the total amount of oil in your engine .
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuo us contact with used engine oil is
harmful to your sk in. A lways protect your
sk in by washing oil off thoroughly w ith soap
and water.

contact a service station .
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter.
The cooling system is sea led and generally re ­
q ui res lit tle atten tion.
The cooling system has been filled at the factory
w ith a pe rma nen t coolan t which does no t need to
be ch anged . T he coolant consists o f a mixture o f
specia lly condit ioned wa ter and the man ufactu r­
er's glycol -based coolant additive Gl3 antifreeze
with anticor rosion add itives (SO% for USA mod­
e ls · 60% for Canadian models) . Th is m ixture bot h
'
assures the nece ssary fros t protection and p ro-
tects meta l components in the engine 's cooling
Checking and Fillin g
system from corrosion and scaling . It also raises
t h e boiling point of the coo lant .
D o no t redu ce the con cen tra tion of the coolan t in
the summer by ad ding plain water.
The prop or­
tion of coolant additive mu st be at least 50%
but not more than 60%
to maintai n antifr eeze
protection and cooling efficiency . If the coo lant
frost pro tec tion is too low, the coo lant co uld
freeze and damage the vehicle heating and en­
gine cooling system .
For year- ro und driving, antifreeze is added at the
factory for temperatures down to :
-- 31°F(-3S° C)USA
- -40 °F ( - 40 ° C) C anada.
If you must add coolant, use a mixture of water
and coolant additiv e. Mix ing the coo lant add it ive
with dis tilled wa te r is recommended .

(D Note
- Befor e wi nter sets in , have the coo la nt
c hecke d to see if the cool an t additive in you r
vehicle is sufficient to meet the climate con ­
ditions . This is espec ia lly impo rtant if you
live in a region where the winter is extreme ­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to yo ur cool ­
ing system, remember:
- We recommend us ing o nly coo la nt addi­
tive G12 ++ o r G13 ( che ck the label) fo r
your ve hicl e. This coolant addi tive is av ail­
a ble at autho rized Aud i dea le rs . Othe r
types of ant ifreeze can significant ly re­
d uce corrosion protection. The resulting
corrosion can ca use a loss o f coolant and
serious engine damage.
- Do not add any type of rad iator leak sealant
to y our vehicle's engine coolant. Adding ra­
diator repa ir fluid may adversely affect the
function and perfo rmance of your cooling .,,.
