The instrument illumination for the needles
and dials turns on when the ignition is turned
on and the lights are turned off. The illumina ­
tion for the dial s reduces automatically and
eventually turns off as brightness outside in­
creases. This function reminds the driver to
turn the headlights on at the appropriate
time.
Engine coolant temperature gauge
The engine coo lant gauge (D ¢ page 10, fig. 3
only works when the ignition is on. To prevent
damage to your engine, please note the follow­
ing important points:

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, heavy en­
gine loads and heavy throttle applications .
Normal temperature
The engine has reached its operating tempera­
ture once the L EDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high . This is no need to worry as long as the.
warning light in the instrument cluster does not
ill uminate.
If the LE Ds in the upper area of the
display and the indicator light. in the instru­
ment cluster display turn on, the coolant temper­
ature is too high

Warm and cold 4-zone deluxe automatic
climate control
Description
A pplies to: ve hicles with four -zone auto matic clim ate con trol
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It
is the most effective when the windows and sun­
roof* are closed. If the temperature ins ide the
parked vehicle becomes very warm, opening the
window briefly will speed up the cooling process.
In a ll heating mode functions except
defrost, the
b lower only sw itches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensation from the cooling system can drip
and form a puddle of water under the veh icle.
This is normal and does not mean there is a leak.
Pollutant filt er
The po llutant filter removes pollutants such as
dust and pollen from the air.
The air poll utants filter must be changed a t the
intervals specified in you r Warranty
& Mainte­
nance booklet, so that the air conditioner can
properly work .
I f yo u drive you r vehicle in a n area with high air
pollu tion, the fil ter may need to be changed
more frequently than specified in your Audi War­
ranty & Maintenance booklet . If in doubt, ask
your author ized Audi Service Advisor for advice.
Key coded settings
The clima te con trol settings are autom atically
stored and assigned to the remo te control key
that is in use.
A WARNING
Reduced visibi lity is dangerous and can ca use
accidents.
Warm and c old
- For safe driving it is very important t hat all
windows be free of ice, snow and condensa­
tion.
- Complete ly familiar ize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield fi rst, using the heat­
i n g and vent ilation system . The was he r so lu­
tion may freeze on the w indshield and re­
duce visibili ty.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid furthe r damage and have it inspected
by a qualified dea lership.
- Repa irs to the Aud i a ir cond itione r requ ire
special techn ica l know ledge and s pe ci al
t oo ls. Cont act an a uthorized Audi de aler fo r
assistance .
@ For the sake of the environment
By red ucing t he amo unt of fuel you use, yo u
also red uce the amount of pollu tan ts emitte d
i nto the air.
(D Tips
- K eep the air intake s lots (in fro nt of the
w indshield) free from i ce , sn ow and debr is
in orde r to maint ain the proper func tion of
the climate control system .
- Th e energy m anagemen t sys tem may switch
t he seat heating* or rear window defros ter
off temporarily. These systems are availab le
agai n as soon as t he energy ba lance has
been restored.

- For safety reasons, you should always park
your veh icle w ith the selector lever in P.
Otherw ise, the vehicle could inadvertently
ro ll away.
- After the eng ine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the
result of a heat buildup or if the engine is
hot and the engine compartment is addi ­
tionally heated by the sun's rays.
(D Note

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 sealed and generally re­
q ui res little atte ntion .
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the ma nufactur ­
er's glycol-based coolant additive G13 an tifreeze
with ant icor rosion additives
(50% for USA mod­
e ls;
60% fo r Canadia n models). This m ix tu re
bo th ass ures the necessa ry fros t prote ction and
protects metal componen ts in the engi ne's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
D o not red uce the con cen trat ion of the coolant in
the summer by adding p lain wa ter.
The propor­
tion of coolant additive mu st be at least 50 %
but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifreeze is added at the
factory for temperatures down to:
- -3 1 °F ( -3 5 °C) USA
- -4 0 °F ( - 40 °C) Canada.
If yo u m ust add coo lant, use a m ixt ure of water
and coolant addit ive. Mixing the cool ant additive
with d istilled w ater is recommended .
_& WARNING
Before you che ck anythi ng in t he eng ine com­
pa rtment, a lways read and heed a ll WARN­
INGS
~ .& in Working in the engine compart­
ment on page 203 .
(D Note
-Before winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the c limate con -
Checking and Filling
ditions. This is especia lly important if you
live in a region whe re the winter is extreme­
ly cold. If necessary, increase the propo rtion
of coolant addit ive to
60%.
- Whe n adding coolant additive to your cool­
ing system, remember :
- We recommend us ing o nly coola nt addi­
tive G 12++ or G13 (c hec k the label) for
y o ur vehi cle. Thi s coo lant ad ditive is av ail­
abl e at a uth orized Au di dea le rs. Ot her
types o f ant ifreeze ca n sign ifican tly re ­
d uce corrosion protection. The resu lting
cor ros ion can cause a loss of coolant and
se rious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling system and could result in damage not cov ­
ered by your New Veh icle Limited War ra nty .
Checking the engine coolant level
The engine coolant level can be checked with a

,&_ WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying light, downward pressure on the top of
the cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving. Seek professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
i n the cap when the engine becomes hot .
- If, in an emergency, only water can be add­ ed, the correct ratio between water and an­
tifreeze
¢ page 209 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulat ions.
-
Checking and Filling
Radiator fan
The radiator fan switches on automatically by it­
self .
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
with the ignition off. It can even switch on again later by itself ¢&. , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­ gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
--
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running .
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature drops.
