A WARNING
-Always observe the warning in¢ page 195,
before open ing the hood and check ing the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment. You
cou ld burn yourself. Let the eng ine cool off
first so that you cannot hear o r see any
steam o r engine coo lant.
0 Note
- Mount ing additional lights or accesso ries in
fron t of the a ir inlets reduces the cooling ef­
fect of the radia to r. A t high outside temper­
atu res or high e ngine load, the eng ine could
overheat.
- The front spo iler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­ ized Audi dealer for assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revo­
lutions per minutes).
If engine RPM drops be low 1,5 00, you should
downshift to the next lower gea r. T he red area at
the end of the scale indicates max imum permis­
sible eng ine RPM after the break-in period . Be­
fore reachi ng this area, move the selector lever to
position D/S or ease your foot off the accelerator
pedal.
(D Note
The tachometer needle@¢ page 10, fig. 3
should o nly briefly be in the red zone: you
co uld damage your eng ine! The beginn ing of
the r ed zone varies depending on the engine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces eng ine
noise .

In add ition , the number of keys init ia lised for
your vehicle is disp layed .
L2 3/3 means that
th ree keys have be en initialised. This feature ena­
bles used car buye rs to make sure they have r e­
c e ived all of the keys.
If you are g iven only two keys, for instance, you
should take the vehicle and the existing keys to
an a utho rized Aud i dea le r to have the miss ing key
disabled.
It i s also important to no tify your insur­
ance company abo ut the loss.

quires immediate service or repair . Driving with a
low-oil-pressure indication is likely to inflict se­
vere damage to the engine.
• Turn off engin e! Oil pressure too low
If the indicator light t urns on and the message
appears, the oil pressure is too low.
• Pull
off the road.

(D Tips
- The engine oil pressure symbol. is not
an indicator for a low engine oil level. Do
not rely on it. Instead , check the oil level in
your engine at regular intervals, prefe rably
each time you refuel, and always before
going on a long trip.
- The yellow oil level warning indication
Ill
requires oil refill or workshop service with ­
out delay. Do not wait until the red oil pressure warning. starts to flash before

Warm and cold
Warm and cold Climate control system
Description
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 pow­
er top are closed.
If there is a build-up of heat in­
side the vehicle , ventilation can help to speed up
the cooling process.
In all heating mode functions except
defrost, the
blower only switches 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 vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Advisor for advice.
Key coded settings
The climate control settings are automatically
stored and assigned to the remote control key
that is in use . These settings are different when
the power top is open or closed.
_& WARNING
Reduced visibility is dangerous and can cause
accidents.
68
- For safe driving it is very important that all
windows be free of ice, snow and condensa­
tion.
- Completely familiarize 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 first, using the heat­
ing and ventilation system . The washer solu­
tion may freeze on the windshield and re­
duce visibility .
(U;) Note
- If you suspect that the air conditioner has
been damaged, switch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repairs to the Audi air conditioner require
special technical knowledge and special
tools. Contact an authorized Audi dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
windshield) free from ice, snow and debris in order to maintain the proper function of
the climate control system.
- The 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.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.

Warm and cold
Operation
We recommend pressing the !AUTO I button and setting the temperature to 72 °F (22 °C).

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not in terfere with the impact-absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind¢,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system ¢.&. .
Safety chains
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the
factory -fitted contro l unit -ris k of acci dent!
- After removing the t railer hi tch, do n ot store
it in your vehicle . In case o f su dden braking,
the hi tch could fly forward and injure you or
your passe ngers.
Operating instructions
Maximum traile r weight
A trai ler for you r vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
B e sure the load in the t ra iler i s held secure ly in
pla ce to prevent it from sh ifting forw ard , back ­
war d or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving in struc tion s on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's pe rform­
ance is up to the additional load . Ma ke s ure that
t h e coo ling system has enoug h fluid.
