@ Tips
The instrument illumination for the needles
and dia ls turns on when the ignition is turned
on and the lights are turned off. The illumina­
tion for the gauges reduces automat ica lly and
eventually turns off as brightness outside in­
creases . T his function reminds the drive r to
turn the low beams on at the approp riate
time.

on. To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold ran ge
If the needle is at the bottom of the gauge, the
engine has not reached operating temperature
yet. Avoid high eng ine speeds, full accelerating
and heavy engine loads.
Normal range
The engine has reached operating temperature
when the needle moves into the center of the
gauge under norma l driving condit ions. The nee­
dle may move farther to the right on the gauge
with heavier engine load at hig h outside temper ­
atu res . If the needle is far ove r on the r ight side
of the gauge and the. in dicator light turns on
i n the instrument cluster, then the coolant tem­
peratu re is too high

high outside temperatures and heavy en­
gine load .
- The front spoiler also he lps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the engine speed is below 1,SOO RPM . The begin­
ning of the red zone in the tachometer indicates
the maximum permissible engine speed for all
gears once the engine has been broken in and
when it is warmed up to operating temperat ure.
Before reaching the red zone, you shou ld shift in­
to the next higher gear, choose the Dor S selec­
tor lever position, or remove your foot from the
accelerator pedal.
CD Note
The needle in the tachometer @Q page 8,
fig. 3 may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting ea rly helps you to save fuel and re­
duces operating noise.
Fuel level
The fuel level indicator only operates when the
ignition is switched on.
The
tD ¢ page 15 turns on if the reserve quan ­
tity of fue l is reached.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ¢ page 210.
CD Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
Instruments and indicator lights
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheat ing and damage
to the catalytic converter.
Odometer
Fig. 4 I n st ru me nt cluster : odometer
Trip odometer and odometer
The trip odometer @ shows the distance driven
since it was last reset. It can be used to measure
short distances.
T he trip odometer can be reset to zero by press­
ing the
10.01 reset button @~ page 8, fig. 3.
The odometer @shows the total distance that
the vehicle has been driven.
Malfunction indicator
If there is a malfunction in the instrument clus­
ter,
DEF will appear in the trip odometer display.
Have the malfunction corrected as soon as possi­
ble.
Time/date display
You can switch between the quartz clock or the
GPS controlled clock* depending on the vehicle
equipment. For more information, refer to your
MMI Operating Manual.
Outside temperature display
The instrument cluster display shows the outside
temperature. At temperatures below 42 °F ( +S
°C), a snowflake symbol appears in front of the
temperature display . .,.
9

Instruments and indicator lights
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actua l temperature
outside due to the heat radiating from the en­
g ine.
A WARNING
Do not assume the roads are free of ice based
on the outs ide temperat ure display . Be aware
that there may be ice on roads even when the
outside temperature is around 42 °F (+5 °C)
a nd that ice can increase the risk of accidents .
You can set the un its used for temperat ure,
speed and other measurements in the Info­
tainment system.
Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on . They indicate funct ions or ma l­
functions . With some indicator lights , messages
may appear and war ning signals may sound .
Some indicator lights are shown in multiple col­
ors in the instrument cluster display.

Warm and cold
Climate control system
Description
Depending on the vehicle equipment, different
systems could be installed:
- manual climate control system or
- automatic climate control system"
The climate control system circu lates, warms or
cools, and removes humidity from the air in the
vehicle interior. It is the most effective when the windows and panorama glass roof" are closed. If
there is a build-up of heat inside the vehicle, ven­
tilation can help to speed up the cooling process .
Pollutant filt er
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key rec ogn ition *
The automatic climate cont ro l system* settings
are stored and assigned to the remote control
key that is in use.
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 ially with the de­
frosting and defogging functions.
- When the temperature is below freezing,
only use the windshield washer system after
the windsh ield has been warmed by the cli­
mate control system. The washer fluid could
Warm and c old
freeze on the windshield and impair visibili­
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 Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an authorized Audi dea ler
or authorized Aud i Service Fac ility.
@) For the sake of the environment
- To save fuel, turn off the climate control
system cooling mode by pressing the A/C
button. This will also reduce emissions . The
cl imate control system is off when the LED
in the button turns off.
- In vehicles w ith the efficiency program*,
you can find other consumptio n information
and more economy tips
¢ page 20.
(D Tips
- To prevent interference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the air intake in
fro nt of the windshie ld must be free of ice
,
snow or leaves.
- Condensation from the cooling system* can
dr ip and fo rm a pudd le of water under the
vehicle. This is norma l and does not mean
there is a leak .
- The energy management system may tem­
porarily switch off certain functions, s uch as
the seat heating* or rear window defogger .
These systems are avai lable aga in as soon
as the energy supply has been restored.

Warm and cold
Manual climate control system
Applies to: vehicles with manual climate control system Fig. 65 Manual climate control system controls
The functions can be switched on and off by
pressing the buttons or adjusted using the dial
and thumbwheel. The
LED in a button will light
up when the function is switched on.
Manual climate control system
For a comfortable temperature in cooling mode,
we recommend :
- in warmer times of the year, set the tempera­
ture so that it is only a few degrees below the
outside temperature.
- set the blower at a moderate speed
- don't direct the air flow directly on the passen-
gers
A/C cooling mode
The cooling mode only functions with the blower turned on. You can turn the cooling system on or
off by pressing the A/C button . The air is not
cooled and humidity is not removed when cooling
mode is switched off. This can cause fog on the
windows. The cooling mode switches off auto-
52
matically when there are cold outside tempera­
tures.
e / e Temperature
The temperature can be adjusted using the Left
dial.
8/5' Blower
Using the center knob, you can manually adjust
the volume of air generated by the blower to your
preferences. The blower should always run at a
low setting to prevent the windows from fogging
and to ensure a continuous exchange of air inside
the vehicle. When the windows are fogged, using
a higher blower speed and setting the knob to@
is recommended.
®l:.0/•.,g/~ Air distribution and vents
The air distribution can be adjusted with the right
knob. The setting between~ and
o,,,o provides a
comfortable atmosphere in most cases.
