Warm and cold
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 follow ing settings:
- Set the temperature to 75 °F (+23 °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 113
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. This
is normal and does not indicate a leak. 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 pollutants filter must be changed at the intervals specified
in your Maintenance
& Warranty 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 Maintenance
& Warranty 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.

Applies to veh icles: with multitronic® Continuously Variable Transm ission (CVT l
General information
Your vehicle is equipped with a electronically controlled continu­
ously variable transmission (multitronic ®l. Inside the multitronic ®
system, the gear ratios are not shi fted in finite steps as in a conven ­
tional automatic transmission, but rather
co ntin uously. As a result,
engine power is applied smoothly and comfortably, and better fuel
economy is achieved.
The transmission selects the appropriate gear ratio (upshifts and
downshifts) automatically based on set driving programs
=> page 163, "Dynamic shift program (DSP)".
You can also manually select a shift program (tiptronic®)
=> page 164.
You should note, that the multitronic transmission differs from a conventiona l Automatic Transmission . In the multitronic transmis­
sion the engine power is transferred via a link -plate chain, rather
than by a conventional torque converter. The multitronic transmis­
sion greatly reduces vehicle "creep'"' when at a standsti ll and the

• Always make sure that the side airbag can inflate without inter­
ference :
- Never install seat covers or replacement upholstery over the
front seatbacks that have not been specifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate.
- Damage to the or iginal seat covers or to the seam in the area
of the side airbag module must always be repaired immedi ­
ately by an authorized Audi dealer.
• The airbag system can be activated only once. After an airbag
has inf lated , it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary .
• The airbag system can be deployed only once . After an airbag
has been deployed, it must be replaced with new replacement
parts designed and approved especially for your Audi model
version. Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .

Energy management
Starting ability is optimized
Energy management controls the distribution of electrical
energy and thus optimizes the availability of electrical
energy for starting the engine.
If a vehicle with a conventional energy system is not driven for a
long period of time, the battery is discharged by idling current
consumers (e.g. immobilizer). In certain circumstances it can resu lt
in there being insufficient energy available to start the engine .
Intelligent energy management in your vehicle handles the distribu ­
tion of electrical energy . Starting ability is markedly improved and
the life of the battery is extended.
Basical ly, energy management consists of
battery di agn osis, idling
current mana gement
and dynami c en ergy management .
Batter y diagn osis
Battery diagnosis continuously deter min es the state of the battery.
Sensors determine battery vo ltage, battery current and battery
temperature . This determines the cu rrent state of charge and the
power of the battery .
Idling c urrent man ag em en t
Idling current management reduces energy consumption while the
vehicle is standing. With the ign it ion switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnos is is considered .
Depending on the battery's state of charge, individual consumers
are gradually turned off to prevent excessive discharge of the
battery and thus maintain starting capability.
Dynamic energ y managem ent
While the vehic le is being driven, dynamic energy management

vidual components . It regulates consumption, so that more e lec­
trical energy is not being used than is being ge nerated and ensures
an optimal state of charge for the battery.
[ i ] Tips
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited .
• I f starting ability is threatened, you are informed by a warning
=> page 266, "Drive r notifica tion i n the instrument cluster
display" .•
What you should know
The highes t pri ority is given to main tain ing starting capa ­
bility.
The battery is severe ly taxed in short-distance driving, in city traffic
and during the co ld time of year. Abundant electrical energy is
required, but only a little is generated. It is also critical if the engine
is not running and elect rica l components are turned on. In this
instance energy is being consumed but none is being generated .
I t is in precisely these situations that you will notice energy manage ­
ment active ly regula ting the distr ibut ion of energy.
Vehicle stands fo r an extended period
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period.
Take into considerat ion that when you un lock your veh icle, some
convenience functions, such as the remote key or power seat
adjustment, may not be availab le . T he conven ience functions will be
available again when you turn on the ignition and start the engine.
