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/.
Fig . 3 Instrument
cluster with digital
clock
The date, time of day, and time and date format can be set in the
MMI. You can find out more in the MMI manual. .,_

& WARNING (continued)
vehicle control and an accident. Have your vehicle repaired imme­diately by your authorized Audi dealer or a qualified workshop.
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 .
Controls and equip ­
ment
Driver information display
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
~ page 76, "Emer­
gency flasher
A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
~ page 324, "Engine compartment".
0 Note
Do not continue driving if the _f_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •
Engine oil pressure malfunction "l::;r.
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil -pres­
sure indication is likely to inflict severe damage to the
engine.
If the 'l::::11 symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also
be displayed by pressing the [CHECK] button:
Switch off engine and check oil level
Immediate actions
- Pull off the road.

• Always remove objects from the instrument panel. Any items
not stored could slide around inside the vehicle while driving or
when accelerating or when applying the brakes or when driving
around a corner.
• When you are driving make sure that anything you may have
placed in the center console or other storage locations cannot fall
out into the footwells. In case of sudden braking you would not be
able to brake or accelerate.
• Any articles of clothing that you have hung up must not inter­
fere with the driver's view. The coat hooks are designed only for
lightweight clothing. Never hang any clothing with hard, pointed
or heavy objects in the pockets on the coat hooks. During sudden
braking or in an accident -especially if the airbag is deployed -
these objects could injure any passengers inside the vehicle. •

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. _.,

Energ y man ag em ent
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
energy are temporarily cut back or switched off=>
page 295.
Heating systems in particular require a great deal of energy. If you
notice, for example, that the seat * or rear window heating is not
heating, they have been temporarily cut back or switched off by
ene rg y m anage ment. These systems are available again as soon as
the energy balance has been res tored .

0 Note
• If you suspect that the air conditioner has been damaged, turn
on ECON and contact an authorized Audi dealer to have the system
inspected.
• Repairs to the Audi air conditioner require special technical
know ledge and special to ols. Contact an authorized Audi dea ler for
assistance.
[ i ] T ip s
• Keep the air intake slots (in front of the windsh ie ld) free from ice,
snow and debris in order to maintain the proper function of the
climate contro l system.
• Air inside the vehicle escapes through air vents located in the
s ide tr im panels beneath the rear side windows. Make sure that the
out let slots are not covered by clothing, etc.
• Climate control works most effectively if the windows and the
Panoramic s liding sunroof* are c losed. However, if the interior of a
parked vehic le is extreme ly hot from the sun's rays, briefly opening
the windows can speed up the cooling process. •
