Instrument s and warning /indicator lights 11
,&_ WARNING
- Always observe the warning in
¢ page 200, Engine compartment, be
fore opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool
i ng effect of the radiator . At h igh outside
temperatures or high engine load, the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over
heat. Ask your authorized Audi dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engin e RPM
(r evolutions per minutes).
If engine RPM d rops be low 1,500 , you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break-in pe
riod . Before reaching this a rea, move these
lector lever to position D/S or ease your foot
off the accelerator pedal.
(D Note
The tachometer needle@¢ page 10,
fig . 3
shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend
ing on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en
gine noise.

Warm and cold Climate controls
Description
Th e climate control sy stem warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
power top are closed. If there is a build-up of
h eat inside the vehicle, ventilation can help to
speed up the cooling process .
I n all he ating mode f unctions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temp erature.
Condensat ion from the cooling sys tem can
d rip and form a puddle of water under the ve
h icle. This is normal and does not mean there
is a leak .
Pollutant filter
The po llutant filte r removes po llutants s uch
as dus t and pollen from the air.
The air pollutants filte r must be changed at
the intervals spec ified in you r Wa rra nty
&
M aintenance book let, so tha t the air condi
tioner can prope rly work .
If you drive your vehicle in an area w ith h igh
a ir po llution , the fi lter may need to be
changed more frequent ly than specified in
your Aud i Warranty
& Ma intenance bookle t. If
in doubt, ask your authorized A udi Service Ad
v isor for advice .
Key coded settings
The clima te control sett ings are automat ically
stored and assigned to the remote co ntro l key
that is in use. These set tings are differe nt
when the power top is open or closed .
& WARNING
Reduced visibility is dangero us and can
cause accidents . -
Warm and cold 69
-For safe driving it is very important that
all windows be free of ice, snow and con
densat ion.
- Comp letely fam iliarize yourse lf with the
proper use and funct ion of the heat ing
and ve nti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the w indshield first, using
the heating and ventilation system. The
washer sol ution may free ze o n the wind

A WARNING ,~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for you r vehi
cle to drive through safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM in order
to raise the engine oil temperature to a mini mum of 140 °F (60 °C) . The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve h icle after the engine is switched off. Howev
er, driving the vehicle to cool it down is part ic
ularly important . Du ring sporty driving, the
engine and brakes, the exha ust system, and
the transm ission all become ext remely hot.
Before you park the vehicle, you shou ld drive
Dri vin g and en vironm ent 185
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down.
Catalytic converter
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in on environmentally sound manner.
"" Always use lead-free gasoline c> page 202,
Fuel supply.
"" Never run the tank down all the way to emp
ty.
"" Never put too much motor o il in your engine
<=> page 212, ~ Adding engine oil .
""Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean
up" device bui lt into the exhaust system of
the ve hicl e. The cata lytic conve rter bu rns
many of t he pollutants in the exha ust gas be
fo re t hey are re leased into the atmosphere.
The exclusive use of unleaded fue l is critically
important for the life of the catalyt ic convert
er and proper funct ion ing of the engine.
A WARNING ~
- The temperature of the exhaust system
is high, both when driving and after stop
ping the engine.
- Never touch the exhaust tail pipes once they have become hot . This could result
in burns .
- Do not park or operate the vehicle in areas where the hot exha ust system may
come in contact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con
verter or heat shields . Dur ing driving, the
substanc e used fo r undercoating could
overheat and cause a fire. •

214 Checking and filling
Engine 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
quires little attention .
The cooling system has been filled at the fac tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-basedcoolant additive G13 antifreeze with
anticorrosion add itives (50% for USA models;
60% for Canadian models). This mixtu re both
assures the necessary frost protection and
protects metal components in the engine 's
cooling system from corrosion and scaling. It
also raises the boiling point of the coolant .
Do not reduce the concentration of the cool
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main
tain antifreeze protection and cooling efficien
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 S °C) USA
- -40 °F ( - 40 °C) Canada .
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~
A in Working in the engine
compartment on page 207.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli
mate conditions . This is especially impor
tant if you live in a region where the win
ter is extremely cold. If necessary, in- crease the
proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using on ly coolant ad
ditive G12++ or G13 for your vehicle.
This coolant additive is availab le at au
thor ized Audi dealers. Other types of
antifreeze can significantly reduce cor
rosion protection. The resulting corro
sion cah cause a loss of coolant and se
rious engine damage.
- Do not add any type of rad iator leak seal
ant to your vehicle's engine coolant .
Adding radiator repair fluid may adverse
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Veh icle
Limited Warranty.
· Checking the engine coolant level and
adding coolant
Be very careful when adding engine coolant.

Coolant loss
Coolant loss may indicate a leak in the coo ling
system . In the event of coolant loss, the cool
i n g system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
Checkin g and fillin g 215
In a sealed system, losses can occur on ly if
the boiling point of the coolant is exceeded as
a resu lt of overheating.
Adding coolant
Rep lacement engine coolant must confo rm to
exact specificat ions¢
page 214, Coolant .
We recommend using only coo lant add itive
Gl2++, Gl3 or i n an emergency Gl 2+ . Do not
use a different add itive. In an emergen cy use
plain water until you can ge t the correct addi

sho uld be done as soon as possib le .
If you have lost a cons iderab le amount o f
coolant, then you sho uld add cold ant ifreeze
and co ld water on ly when the engine is cold.
A lways use
new engine coo la nt when refilling.
Do not fill coolant above the "MAX" mark. Ex
cess coolant will be fo rced out through the
pressure relief valve in the cap when the en
gine becomes hot.
