The display@ Q page 10, fig. 3 only works
when the ignition is sw itched on . When the
d isplay has reached the reserve mark, the bot­
tom LED wi ll turn red and the
tD indicator
light turns on

computer display.
F or the tank capac ity in yo ur vehicle , refer to
the Tec hnical Data
Q page 288.
CJ) Note
Never d rive until the tank is completely
empty. The irregular supp ly of fuel that re­
sults from that can cause the engine to
misfire. Uncombusted f uel will then enter
the exha ust system. This can cause over­
heating and damage to the catalytic con­
verter .
Coolant temperature indicator
In vehicles without a coolant temperature in­
d icator , an indicator l ight . will turn on
when the coolant temperature is too h igh
Q page 20. Refer to Q Q) .
The coolant temperature ind icator @
c::> page 10, fig . 3 only works when the ignition
is switched on . T o prevent engine damage, ob­
serve the fo llow ing notes about the tempe ra­
ture ranges.
Cold range
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high engine speeds,
fu ll acce le rat ing and heavy engine loads.
Norm al range
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions. The L EDs higher up may turn on if the
engine is under heavy load or the o uts ide tern- perature is h
igh. This is not a cause for con­
cern as long as th e . indicator light in the
display does not turn on.
Hot range
If the L EDs in the upper area of the disp lay
and the. indicator light in the instrument
cluster disp lay t urn on , the coo lant tempera ­
ture is too high
c::> page 20.
A WARNING
I-
- Always observe the warn ing in
c::> page 217, before opening the hood
and checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coo lant
dripping from the engine compartment.
You could burn yourse lf . Let the engine
coo l off f irst unti l yo u can no longe r see
or hea r steam or coolan t escap ing.
Q) Note
- In vehicles w ith a boost pressure indica­
to r*, this indicator replaces the tempe ra­
t ur e display. To promote a long engine
service life, avoiding h igh engine speeds,
full acceleration and he avy eng ine lo ads
during approximately the first 15 m i­
nutes when the engine is co ld is recom ­
mended. The amount of time until the
eng ine is warm depends on the outside
temperat ure. Check the engine oil tem­
perature* if necessary.

- Add itiona l head lights and other compo­
nents in front of the air intake impairs
the cooling effect of t he coolant. This in­
creases the risk of the engine overheat­
ing during high outs ide temperatures
and heavy eng ine load.
- T he front spoiler also he lps to d istr ibute
cooling ai r correctly wh ile driving. If the
spoiler is damaged, the coo ling effect
w ill be imp aired and the risk of the en­
gine overhea ting will increase . See an au­

!?i Engine speed limitation
App lies to vehicles: with engine speed limitation
Ill Max. engine speed: XXXX rpm
-
The engine speed is automatically limited to
the speed displayed in the driver information
system. This protects the engine from over­
heating .
The engine speed limitation deactivates once
the engine is no longer in the c ritical tempera­
ture range and you have released the accelera­
tor pedal.
If the engine speed limitation was activated
by an engine control malfunction, the
Di indi­
cator light also turns on. Make sure the en­
g ine speed does not go above the speed dis ­
played, for example when downsh ifting . Drive
to an authorized Audi dealer or author ized
Aud i Service Facility immediately to have the
malfunction corrected.

If the indicator light turns first turns on and
t his message appears, the tan k contains the
following amount of fuel:
- Front wheel dr ive : approximately 1.8 gal­
lons (7 liters)
- All wheel dr ive : approximately 2.2 gallons
(8 .5 liters)
II] Please refuel immediately
If the indicator light turns on the message ap­
pears, the fuel tank is almost empty. Refuel
the vehicle immed iate ly.

68 Warm and cold
Warm and cold Climate control system
Description
Different systems cou ld be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and panorama 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 .
9 page 43, Convenience opening/
closing
Pollutant filter
T he pollutant 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 accidents.
- For safer driving, keep all windows free
of ice, snow and fog .
- Become familiar as quickly as possible
with the correct use and function of the cl imate control system, especially with
the defrosting and defogg ing funct ion .
- When the temperature is below freezing,
only use the windsh ield washer system
after the w indshield has been warmed by the cl
imate control system . The washer
fluid could freeze on the windshield and
impair visibility.
(D Note
- If you suspect that the climate control
system 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 sys­
tem require special technical knowledge
and special tools. See an authorized Audi
dealer or authorized Audi Serv ice Facility .
® For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter
the air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can dr ip and form a puddle of water un­
der the vehicle. This is normal and does
not mean there is a leak.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly . These systems
are available again as soon as the energy
balance has been restored.
- The flows through the vents under the
rear window. Make sure the openings are
not covered when placing clothing on the
luggage compartment cover.
