Coolant temperature indicator
The coolant temperatu re display (D ¢ page 10,

or ¢ page 10, fig . 3 only functions when
the ignition is switc hed on . To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold rang e
If onl y the L EDs at the bottom o f th e ga uge tu rn
on, the engine has not reached operating tem ­
pe rature yet. Avoid high engine speeds, full ac ­
celerat ing and heavy engine loads .
Normal range
The engine has reached its oper ating temper a­
ture once the LEDs up to the center o f th e ga uge
turn on. If
the . indicator lig ht in the instru­
ment cluster display turns on, the coolant tern -
~ perature is too high ¢ page 25 .

outside temperature.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
T he beginning of t he red zone in the tachometer
indicates the maxim um permissible engine speed
for all gea rs once the engine has bee n broken in
and when it is warmed up to operating tempera­
ture . Before reach ing the red zone, you sho uld
sh ift into the next h igher gear, choose the "D" or
" S" se lecto r lever pos it io n, or remove yo ur foot
from the ac cele ra tor ped al.

CD Note
The needle in the tachometer @ Q page 10,
fig. 4 or¢ page 10, fig. 3 may only be in the
red area of the gauge for a short time or there
is a risk of engine damage. The location where
the red zone beg ins varies depending on the
eng ine .
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duces operating noise .
Fuel level
The display@¢ page 10, fig. 4 or ¢ page 10,
fig. 3 only functions when the ign ition is swi tch­
ed on . When the display has reached the reserve
mark, a red LED appe ars and the

light t urns on ¢
page 28. The LED blinks red
when the f uel level is very low .
For the tank capacity in yo ur vehicle , refer to the
Te chnical Data
¢ page 38 2.
CD Note
Never d rive until the tank is comple tely emp­
t y. The irregular supp ly of fuel that resul ts
from that can ca use engine misfi res . U ncom­
bus ted fuel will the n enter the e xhaus t sys ­
tem . This can cause overheating and damage
to the cata lytic conve rter .

Trip odometer and odometer
The trip odometer shows the dis tance driven

short d istances.
The trip odometer ca n be reset to zero by p ress­
i ng t he rese t button ®¢
page 10, fig. 4 or

The odometer shows the total d istance that t he
vehicle has been drive n.
Malfunction indicator
If there is a malfunction in the instrument clus­
te r,
DEF will appear in the trip odome ter display .
Have the malfunction corrected as soon as possi­
ble.
Outside temperature display
If your vehicle i s sta tionary or if yo u are driv ing at
very low speeds, t he temperature d isplayed may
be slight ly higher than the actual temperatu re
outside due to the heat radiating from the en ­
gine .
At temperatures be low 41 °F (+S °C), a snowf lake
symbol appears in front of t he temperature dis­
play ¢.&. .
A WARNING
Do not assume the roads are free of ice based
on the outside tempe rature disp lay. Be aware
that t here may be ice on roads even when the
outside temp erature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents .

Warm and cold
Warm and cold Climate control system
Description
The climate control system circulates , warms or
coo ls, and removes humid ity from the air in the
veh icle interior . It is the most effective when the
windows and panorama g lass roof* or power top*
are closed. If there is a build-up of heat inside
the vehicle, ventilation can help to speed up the
coo ling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and po llen from the air.
Key recognition
Various sett ings are stored and ass igned to the
remote control key being used.
These settings are different when the power top* is open or closed .
Presetting
Several functions can be preset in the Infotain­
ment system.
Select in the Infotainment system:
IMENU ! but­
ton
> Vehicle > left control button > Air condi­
tioning
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar with the correct use and
function of the climate control system as
quickly as poss ible, espec ia lly with the de­
frosting and defogging functions.
- When the temperature is below freezing, only use the windsh ield washer system after
68
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visib ili­
ty .
@ Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Aud i dealer or authorized
Audi Serv ice Facility.
- Repa irs to the Aud i climate control system
require special technical knowledge and
special tools . See an authorized Aud i dealer
o r authorized Aud i Serv ice Facility .
@ For the sake of the environment
-To save fuel, turn off the climate control
system cooling mode by press ing the A/C
button. This w ill also reduce emissions . The
climate control system is off when the LED
in the button turns off.
- In vehicl es w ith the efficie ncy prog ram*,
yo u can find other consumpt ion information
and more economy tips ¢ page 19.
© Tips
- To prevent int erference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
drip and form a pudd le of water under the
vehicle . This is normal and does not mean
there is a leak.
- Th e energy management system may tem ­
porarily switc h off certain functions, such as
the seat heating* or rear window defogger.
These systems are ava ilable again as soon
as the energy supply has been restored.
