The illumination for the instrument cluster lights up whenever you
switch on the ignition with the
vehic le headlights off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and will go out completely when the outside light is
very low. This feature is meant to remind you to switch on the head­
lights when outside light conditions become poor. •
Engine coolant temperature gauge
The engine coolant gauge=> fig. 2 G) only works when the ignition
is on. To prevent damage to your engine, please note the following
important points:
Engine cold
As long as th e needle remains at or close to the bottom of the
gauge, the engine still has not reached its operating temperature .
Avoid high engine speeds , heavy engine loads and heavy throttle
applications.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the middle of the gauge and remain there. If the
engine is working hard at high outside temperatures, the needle
may rise up . This is no need to worry as long as the
_f_ warning light
in the instrument cluster does not illuminate . .,

Instruments and warning/indicator lights
Warning light in the instrument cluster -t
When the _L warning light in the instrument cluster starts to flash,
this can mean one of two things: either the coolant
temperature is
too high, or the coolant
level is too low~ page 33.
If the needle is well in the upper area of the gauge, the coolant
temperature is too high.
Stop the vehicle, switch the engine off and
allow the engine to cool.
If the warning light comes on again after
driving a short distance, contact an authorized dealer.
& WARNING
• Always observe the warning in ~ page 324, "Engine compart­
ment", 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 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.
0 Note
• Mounting additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator. At high outside tempera­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle 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 engine RPM (revolutions per
minutes).
The tachometer 0 ~ page 13, fig. 2 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 below 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 period. Before reaching
this area, move the selector lever to position "D (Drive)" or ease your
foot off the accelerator pedal.
0 Note
The tachometer needle should not move into the red range. If it
does, then only for a
very short period of time. You could damage
your engine by driving at high RPM .
'£> For the sake of the environment
Upshifting early saves fuel and reduces engine noise.•
Digital clock with date display
Date and time of day can be set in the MM/.

Drive slowly and avoid sudden, hard brake applications. •
Engine cooling system malfunction -L
A mo/function in the engine cooling system must be
repaired as soon as possible.
When the _ t symbol in the display blinks, then either the
engine coolant temperature is too high, or the coolant level
is too low. An additional driver message can also be
displayed by pressing the [ CHECK] button:
Switch off engine and check coolant level
- Pull off the road .
- Stop the vehicle.
- Turn off the engine.
- Check coolant level => page 338.
- Add coolant if necessary => page 339.
- Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the O warning symbol (alternator malfunction) also lights up on
the instrument panel~
page 32, then the fan belt may be damaged .

Climate control
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 72 °F (+22 °C).
- Press the [AUTO
I button.
With this setting, you attain maximum comfort 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 automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically
regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
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 126
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . Th is
is normal and does not indicate a leak.
Controls and equip ­
ment
If the outside temperature is low, the fan normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated
charcoal filter) reduces or prevents outside air pollution (dust, or
pollen) from entering the vehicle. The air is also filtered in air recir­
culation mode.
The air pollutants filter must be changed at the intervals specified in your Warranty
& Maintenance 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 Warranty
& Maintenance booklet . If in doubt, ask your autho ­
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored. _.,

P ress [ AUTO I => page 125, fig . 135.
Automatic operation ensures constant temperatures in the interior
and dehumidifies the air inside the vehicle. Air temperature, vo lume
and distribution are contro lled automatica lly to reach or maintain
the desired inter ior temperature as quickly as possible. Fluctuations
in exterior temperature and the effects of temperature from the
pos ition o f the sun are compensated for automatica lly.
T his operating mode works only in the adjustable temperature
r ange, from 60 °F (+ 16 °C) to 84 °F (+28 °C). If a temperature below
60 °F
( + 16 °C) is selected, LO appears in the disp lay. At temperatures
above 84 °F ( +28 °C),

& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• For safety reasons, you should always park your vehicle with
the selector lever in P. Otherwise, the vehicle could inadvertently roll away.
• After the engine 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 additionally heated
by the sun's rays.
0 Note
If the engine has been under heavy load for an extended period,
heat builds up in the engine compartment after the engine is
switched off -there is a risk of damaging the engine. Allow the
engine to run at idle for about 2 minutes before switching it off. •

Driver messages in the instrument cluster
display
If a function is not present, a driver message appears.
No key identified
This message appears when the [STAR T) button is pressed if there
is no master key inside the vehicle or if the system does not recog­
nize it . For example, the master key cannot be recognized if it is
covered by an object (e.g. aluminum brief case) which
screens the radio signal. Electronic devices such as cell phones can also inter­
fere with the radio signal.
Press brake pedal to start engine
This message appears if you press the [ START) button to start the
engine and do not depress the brake pedal. The engine can only be
started if the brake pedal is depressed.
Engage N or P to start engine
This message appears when the engine is started if the selector
lever for the automatic transmission is not in the P or N position.
The engine can only be started with the selector in these positions.
? Key not in vehicle
This message appears along with the symbol if the master key is
removed from the vehicle with the engine running. It is intended to
remind you (e.g. when changing drivers) not to continue the journey
without the master key.
If the master key is no longer in the vehicle, you cannot switch off
the ignition after stopping the engine and you also cannot start the engine again. Moreover, you cannot lock the vehicle from the
outside with the key.
Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
is not in
P.
This message appears for safety reasons along with a warning
buzzer if the selector lever for the automatic transmission is not in
the P position when the ignition is switched off with the
[STOP)
button and the driver's door is opened. Move the selector lever to
the P position, otherwise the vehicle is not secured against rolling
away. You also cannot lock the vehicle using the locking button on
the door handle or using the remote key.

pillar. On Canada vehicles, the tire pressure label is located either on
t he driver's side 8 -pillar or inside the fuel fil ler flap. Inflate trailer
tires to trailer and tire manufacturers' specifications.
L ight s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Sa fety c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle . Leave enough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the road when you are driving .
The chains should cross under the tra iler tongue to prevent it from
dropping in case of separation from the hitch.
0 Note
If you are going to tow a traile r, you must activate the trailer opera ­
tion mode =>
page 211, "Towing a trailer" .
Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the fo llow ing:
- Do not tow a loaded trailer when your car i tse lf is not
loaded .
- Be especia lly careful when passing other vehicles .
- Observe speed l imits.
- Do not drive at the maximum permiss ible speed .
Controls and equip­
ment Safety first Vehicle operation
Tr
aile r t owing
Always apply brakes early .
- Monitor the temperature gauge .
Weigh t dis tr ibution
Towing a loaded trailer wi th an empty car results in a highly
unstable dis tribution of weight . If this cannot be avoided , drive at
very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations .
Speed
The higher th e speed, the more difficu lt it becomes for the driver to
control the rig . Do not drive at t he maximum pe rmissible speed.
Reduce your speed even more
if load, weather or wind conditions
a re unfavorable -particularly when going downhil l.
Reduce vehicle speed
i mmedi ate ly if the trailer shows the slightest
sign of swaying.
Do not tr y to s top the swaying by accelerating .
Observe speed limits . In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coo lant t emperatu re
The coolant temperature gauge=> page 13 must be obse rved care ­
ful ly. If the need le moves close to the upper end of the sca le , reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts f lashing
- f- , pul l off the road, stop and let the engine idle for
about two minutes t o prevent heat build -up.
