Engine coolant temperature gauge
The eng ine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To p revent
damage to you r engine, please note the fol­
lowing impor tant po ints:
Engine cold
As long as the needle remains at or close to
the bottom of the gauge, the engi ne still has
not reached its operat ing temperature . Avoid
high eng ine speeds, heavy eng ine loads and
heavy th rottle a pplicat io ns.
Normal temperature
When the engine has reached its operat ing
temperature, the needle w ill move into the
midd le of the gauge and rema in the re. If th e
engine is worki ng ha rd at high outside tem­
peratures, the needle may rise up. This is no
need to worry as long as the. warni ng lig ht
i n the i nstr ument cluster does not ill uminate.
Warning light in the instrument cluster
When the. warning lig ht in the instr ument
cluster s tarts to flash, th is can mean one of
two things : either the coo lant
temperatur e is .,..

too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 256, before 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
dr ipping from the engine compartment.
You could bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine 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 cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed 1,000
times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM.
If engine RPM drops 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 area , move these­
lector lever to position D (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .
Digital clock with date display

Warm and cold Climate control
Description
The air conditioner is fully automatic and is
designed to maintain a comfortable and uni­
form climate inside the vehicle .
We recommend the following settings :
.. Set the temperature to 72 °F (+22 °C).
.. Press the
!AUTO ! button.
With this setting, you attain maximum com­
fort in the least amount of time. Change this
setting, as desired, to meet your personal
needs.
The climate controls are a combination of
heating, ventilation and cooling systems,
which automatica lly reduce humidity and cool
the air inside your vehicle.
The air temperature, air flow and air distribu­
tion are automatica lly regu lated to achieve
and maintain the desired passenger compart­
ment temperature as quick ly as possib le.
The system automatically compensates for
changes in outside temperature and for the
intensity of the sunlight entering the vehicle.
We recommend you use the
Automatic mode
¢ page 97 for year-round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity
in the vehicle . Thi s also prevents the windows
from fogging up.
When the outside temperature is high and the
a ir i s very humid,
condensation from the
evaporator may drip under the vehicle. This is
norma l and does not indicate a leak.
If the outside temperature is low, the fan nor­
mally only switches to a h igher speed once
the eng ine coolant has warmed up sufficient­
l y.
The air conditioner temporarily switches off
when you drive off from a standstill using full
thrott le to save eng ine power. The
compressor a lso switches off if the coo l­
ant temperature is too high , so that the en­
gine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filt er (a comb ined particle
filter and activated charcoa l filter) reduces or
prevents outside air pollution (dust, or pollen)
from enter ing the vehicle. The air is also fil­
tered in air recirculation mode .
The air pollutants filt er must be changed at
the interva ls specified in your Warranty
&
Maintenance booklet, so that the a ir condi­
tioner 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 Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The air conditioner settings selected are auto­
matically stored and assigned to the key be ing
used. When the vehicle is started, the air con­
ditioner automa tically selects the settings as­
s igned to that key. This way every driver will
maintain h is/her own personal settings and
does not have to reset them manually .
If a different dr iver uses your key and changes
the a ir cond itioner settings, the latest adjust­
ments will e rase and replace the settings you
have stored.
Energy management
To prevent the battery from being discharged
and to restore the balance of energy, compo­
nents which require large amounts of energy
are temporarily cut back or switched off
¢ page 228. Heating systems in pa rticular re­
quire a great deal of energy.
If yo u notice , fo r
example, that the seat* or rear window heat­
ing is not heating, they have been temporarily
cut back or switched off by
energy manage­
ment.
These systems are availab le aga in as
soon as the energy balance has been restored . .,.

The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case of
separation from the hitch.
0 Note
If you are going to tow a tra ile r, you must
activa te the trailer operation mode
~ page 161, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
cor e and consid eration.
To obta in the best poss ible handling of vehicle
and tra ile r, p le ase no te the following:
.. Do not tow a loaded tra iler when your car it­
self is not loaded.
.,. Be especia lly careful when pass ing othe r
vehicles .
.. Observe speed limits.
.. Do not driv e at the maximum p ermissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight di stributio n
Towing a loaded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of losing
steering control.
A "balanced" rig is eas ier to operate and con ­
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances. Whenever possi­
b le, transfer some cargo to the luggage com­
pa rtment of the tow veh icle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permiss ible speed . Re- duce your speed even more i
f load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do not
t ry to stop the swa ying by acceleratin g.
Observe speed limits. In some a reas, speeds
f or vehicles tow ing tra ile rs are lower than for
r egular vehicles.
Always apply brakes early. When driving down hill, shift into a lowe r gear to use the en­
gine braking effect to s low the vehicle . U se o f
the brakes alone can cause them to overheat
and fail.
Coolant temperature
T he coo lant tempe ratu re gauge ~ page 10
must be observed caref ully. If the need le
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warn ing light in
the instr ume nt cluster starts flashing., pull
off the road , stop and let the engine
idle for
about two min utes to prevent heat build -up .
A WARNING "--
Anyone not proper ly restrained in a mov-
i ng vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
p rov ided by Audi .
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
-
a trai ler because of the additional weight and
different weight distr ibut ion. Safety, perform­
ance and economy will great ly depend on how
ca refully you load your tra iler and operate
yo ur rig .
Before you act ua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep pract ic ing unt il you
