A WARNING
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.
@ Tips
- Depending on vehicle equipment, the in ­
strument illumination (needles and gauges) may turn on when the lights are off and the
ignition is switched on . The illumination for
the gauges reduces automatically and even­
tually turns off as brightness outside in­
creases. This function reminds the driver to
turn the low beams on at the appropriate
time .
- You can select the units used for tempera­
ture, speed and other measurements in the
Infotainment system
c::> page 248.
- If your vehicle is stationary or if you are driv­
ing at very low speeds, the temperature dis­
played may be slightly higher than the ac­
tual temperature outside due to the heat ra­
diating from the engine .
- At temperatures below 41 °F ( +5 °C), a
snowflake symbol appears in front of the
temperature display
c::> A .
Coolant temperature indicator
The coolant temperature
display @c::> page 10,
fig. 3 or c::> page 10, fig. 4 only functions when
the ignition is switched on. To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet . Avoid high engine speeds, full ac­
celeration and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on. If
the. indicator light in the instru-
Cockpit overview
ment cluster display turns on, the coolant tem­
perature is too high
c::> page 30.
(D Note
- Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en­
gine load.
- The front spoiler also helps 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 .
@ Tips
Diesel engines: due to the high efficiency of
these engines, the engine may not always reach operating temperature in cold outside
temperatures . This is normal and not a cause
for concern.

Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions except for
defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y recognit ion
The climate control settings are automatically
stored and assigned to the remote contro l key
that is in use .

® For the sake of the environment
-If you would like to reduce fuel consump­
t ion, sw itch the air conditioning
off. This
will also reduce emissions.
- In veh icles with a diesel engine, you can
switch the auxiliary heater
off in the Info­
tainment system.
(D Tips
- To prevent interference with the heating
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
dr ip and form 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, such as
the seat heating* o r rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy supply has been restored.

tion swi tches off automatically afte r abou t 15
minu tes .
A WARNING
- You should not use the recirculation mode for an exten ded period of time, because no
fresh a ir is drawn in and the w indows can
Warm and c old
fog when cooling mode is switched off. This
increases the r isk of an accident.
- Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heat ing* function. To reduce
the risk of injury, these individua ls should
not use seat heating*.
