Economical operation of the air conditioner will help to
save fuel.When the air conditioner is operating in the cooling mode it
reduces engine power and increases fuel consumption. To
ensure that the cooling mode is activated only when really
necessary, please note the following points:
– Switch off the cooling mode by pressing the AC button
(LED off) if you wish to save fuel.
– You should also switch off the cooling mode by pressing
the AC button (LED off) if you open the windows or the
tilting panorama roof* while driving.
– If the vehicle has heated up after standing in the sun,
open the windows and doors for a short time to cool the
vehicle.
For the sake of the environmentBy saving fuel you also reduce the amount of pollutants emitted
from your vehicle.

Heating and cooling 102The compressor also switches off if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
Pollution filter
The pollution filter (a combined particle filter and activated charcoal
filter) serves as a barrier against impurities in the outside air,
including dust and pollen, and against unpleasant smells. The air is
also filtered when the air recirculation mode is activated.
For the air conditioner to work with maximum efficiency, the pollu-
tion filter element must be replaced at the intervals specified in the
Service Schedule.
If the vehicle is driven in areas with a high level of air pollution and
the filter is no longer fully effective, it may be necessary to change
the filter element more frequently.
Key-coded settings
The currently selected air conditioner settings are automatically
stored and assigned to the remote control key.
Power management
To prevent the battery from becoming discharged and to maintain
the necessary power level, the system will temporarily shut off the
electrical components that are using a lot of power, or reduce the
current they are consuming ⇒page 202. Heating systems in partic-
ular use a large amount of electrical power. If you notice, for
instance, that the rear window heater is not working, it may have
been temporarily switched off by the power management function,
or regulated to a lower heat output. These systems will be available
again as soon as sufficient electrical power is available.
WARNING
For safety reasons it is important that all the windows are kept
free of ice, snow and condensation. These can cause poor visibility
and lead to an accident. Please familiarise yourself with the oper-
ating controls for the air conditioner, including the demist/defrost
functions for the windows.
Caution
•
If you suspect that the air conditioner is damaged, switch it off
to prevent further damage and have the system checked by a quali-
fied workshop.
•
Repairs to the air conditioning system require specialist knowl-
edge and special tools. For this reason, please contact a qualified
workshop if the system is not working properly.Note
•
Keep the air intake slots in front of the windscreen clear of snow,
ice and leaves to ensure unimpaired heating and cooling, and to
prevent the windows misting over.
•
The air from the outlets flows through the passenger compart-
ment and out through the slots at the rear of the vehicle. Do not
cover these slots with clothing or other objects.
•
The air conditioner operates most effectively with the windows
and the tilting panorama roof* closed. However, if the vehicle has
heated up after standing in the sun for some time, the air inside can
be cooled more quickly by opening the windows for a short time.

Applies to vehicles: with deluxe automatic air conditioner plusAutomatic recirculation
If the outside air is polluted, an air purity sensor in the
vehicle will automatically switch on the air recirculation.To prevent fumes, etc. in the outside air from entering the interior,
we recommend that the automatic air recirculation should be
switched on at all times.
If the air purity sensor in the air conditioner system detects a certain
concentration of fumes in the outside air, the control unit will either
pass the incoming air through the pollution filter or automatically
switch on the air recirculation. If there is a high concentration of
pollution in the outside air, the air conditioner automatically
switches to air recirculation and cuts off the supply of air from the
outside. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
If the windows mist up when the automatic air recirculation is on,
press the
 button immediately.The automatic air recirculation can switch itself off in certain condi-
tions. If the outside temperature is less than about +10 °C, the auto-
matic air recirculation will only operate for 30 seconds. If the air
conditioner is switched to the ECON mode, or if the outside temper-
ature is less than about -1 °C, the automatic air recirculation will
only operate for 15 seconds.
Applies to vehicles: with deluxe automatic air conditioner plusSynchronisation
The air conditioner settings can be synchronised for all
passengers.When the synchronisation function is on, the driver's settings are
also applied to the front passenger or vice versa. Any subsequent
changes to the air conditioner settings (except for the seat heating*)
are also applied to the other occupant.
You can still change the setting on the “synchronised” side (this will
deactivate the synchronisation function).Applies to vehicles: with diesel engineSupplementary heater– Set the Supplementary heater to auto or off.Models with a diesel engine are equipped with a supplementary
heater to help warm up the interior more quickly. At outside temper-
atures below about +5 °C the supplementary heater is switched on
(and off) automatically when the engine is running, depending on
the coolant temperature, the temperature in the vehicle interior and
the temperature the heater is set to.

Technical data lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
 in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.
As soon as you drive off in the normal way, the parking brake will
automatically be released and the vehicle will start moving.
If the conditions for Audi hold assist change and the function is
switched off as a result, the parking brake will be applied automati-
cally to ensure that the vehicle is parked safely. The diode in the
button will go out when the Audi hold assist function is switched
off.
WARNING
The intelligent technology in Audi hold assist cannot defy the laws
of physics. Do not let the extra convenience provided by Audi hold
assist tempt you into taking a safety risk.•
Audi hold assist cannot keep the vehicle stationary in all condi-
tions on a gradient (e.g. if the road is slippery or icy).
•
Audi hold assist must be switched on again each time the
engine is started – Risk of accident!
•
Never get out of the vehicle when the engine is running and
Audi hold assist is switched on – Risk of accident!
•
Always ensure that the vehicle is stopped properly and safely
to avoid injury to yourself and others.Caution
Switch off the Audi hold assist function before driving the vehicle
into a car wash.
Note
•
Audi hold assist can be switched on only when the driver's door
is closed, the driver's seat belt is buckled and the engine is running.
•
Audi hold assist prevents automatic vehicles from creeping
forwards when the brake pedal is released with the car in gear.

Driving 126The cruise control system allows you to drive at a constant speed of
30 km/h or higher.
A constant speed is maintained by adjusting the engine power or
braking the vehicle accordingly (while in cruise mode).
The cruise control system is set using the control lever ⇒page 125,
fig. 138. The indicator lamp lights up while the system is operating
⇒fig. 139.
The cruise control system is automatically deactivated immediately
when you press the brake pedal.
On vehicles with a manual gearbox, the cruise control system will be
deactivated if the clutch is pressed for a long time.
WARNING
•
Always direct your full attention to the road, even when you are
using the cruise control system. It is always you who is respon-
sible for determining your speed and for keeping a safe distance
to the other vehicles on the road.
•
For safety reasons, the cruise control system must not be used
in city traffic, stop-go traffic, roads with a lot of bends or in diffi-
cult driving conditions (such as ice, fog, loose grit or gravel, heavy
rain, aquaplaning) - this could cause an accident!
•
When you take a turn-off, drive along a motorway exit lane or
pass through roadwork sections, please temporarily switch off the
cruise control system.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the cruise control system which,
as a result, will not brake the vehicle.Caution
On vehicles with a manual gearbox: do not move the gear lever into
neutral without depressing the clutch when the cruise control
system is active. Otherwise the engine could rev up and be
damaged.
Note
•
On vehicles with a manual gearbox, the set speed cannot be
reached if the currently selected gear is too high or too low. Change
down to a lower gear when the engine no longer runs “smoothly” or
change up a gear to avoid overrevving the engine.
•
The brake lights come on when the system brakes the vehicle.
