Warm and cold
Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 75
°F (+23 °C).
- Press the
[AUTO] 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 106
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.
Controls and equip ­
ment Safety first
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 char­
coal 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 Warranty
& Maintenance 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
Warranty
& Maintenance booklet. If in doubt, ask your authorized
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.

& WARNING (co ntinued )
• Always make sure that the side airbag can inflate without
interference:
-Never install se at 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 original 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 sy stem can be activated only once. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary.
• The airbag sy stem can be deployed only onc e. After an airbag
has been deployed, it must be replaced w ith new replacement
parts de signed and approved es pecially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD.
• For safety reasons in severe accidents, the alternator and
starter are separated from the vehicle battery with a pyrotechni c
circuit interrupter .
- Work on the pyrotechnic circu it interrupter must only be
performed by a qualified dealer -risk of an a ccident!
- If the vehicle or the circu it interrupter is scrapped, all appli­
cable safety precautions must be followed .

Other things that can affect Advanced
Airbag performance
Chang ing the ve hicle's suspension system can change the way that

W inter tires
When d riving in the winter, your vehicle with A ll Whee l Drive has an
advantage, even with reg ula r tir es . In wi nter road cond it ions i t may
be advisab le to mount w inte r tires (or all-season tires) for imp roved
dr iveabili ty and braking: these tires m ust be mounted on
all four
wheels .
See also => page 323, "Winter tires".
Tire chains
Whe re tire chains are mandato ry on certa in roads, this normally also
applies to veh icles with A ll Whee l Drive=>
page 324, "Snow chains ".
Replacing wheels/tires
Veh icles with All Wheel Drive m ust always have t ires of the same size.
Also avoid tires with different trea d de pths . For details see page
=>
page 318, " N ew tires and replac ing tires a nd wheels" .
Off-Road driving?
Your Audi does not have enough ground clearance to be used as a n
off -road vehi cle. It is the re fore best to avoid ro ug h trac ks and uneven
ter rain as muc h as poss ib le. Also re fer to=>
page 263 .
& WARNING
Always adjust your dri ving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking ex tra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is l imited by tire traction. You
should therefore not drive at exce ssive speeds on icy or slippery
road surfaces.
• On wet road surfa ce s, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua­
planing ). If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle. Always drive at speeds which are suited to the road condi­
tions - risk of crash. •
Energy management
Starting ability is optimized
Energy m ana gemen t con tr ols the distributi on of elec­
trical ener gy an d thu s optimiz es the ava ila bility of elec­
t ri cal ene rgy f or starting the en gine.
If a vehicle w ith a convent iona l energy system is not driven for a long
pe riod of time, t he b att ery is di sch arged by idling current con sumers
(e .g. immob ilize r). In certain c ircumstances it can result i n there
be ing insuffi cien t energy avai lab le to s tar t the engine.
I n te lligent e ne rgy management in yo ur vehicle ha ndles the dist ribu­
tion of e lectrical energy . Starting ab ility is ma rkedly improved and
t he life of the battery is extended.
Basically, energy management consists of
battery diagnosis , idling
current management
a nd dynamic energy management .
Battery diagnosis
Batte ry diagnosis co nti nu ously deter mi nes the s tate of the batte ry .
Sensors determine battery vo ltage, battery current and battery
t empe rature. This determines the cur rent sta te of charge and the
power of the battery.
Idling current management
Id ling current management red uces energy consumpt ion while the
veh icle is s tanding. W it h t he ignition swi tched off, it con trol s the
energy supply to the var ious electrica l components. Data from
b attery di ag nos is is conside red .
Depe nding on the batte ry 's state of charge, individ ua l consumers a re
gradually t urne d off to prevent excessive discha rge of the batte ry an d

vidual components. It regulates consumption, so that more electrical
ene rgy is not being used than is being generated 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.
• If starting ability is threatened, you are informed by a warning
~ page 259, "Driver notification in the instrument cluster display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
Th e battery is severely taxed in short-distance driving, in city tra ffic
and during the cold time of year. Abundant electrical energy is
required, bu t on ly a little is generated .
It is also critical if the engine
is not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in prec isely these situations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for 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.
Be aware that when you unlock your vehicle, some of the convenience
functions may not operate, such as the Convenience key, the remote
control or the power seat adjustment. The convenience functions will
be available aga in when you turn on the ignition and start the eng ine.
Controls and equip­
ment Safety first Vehicle operation
With the
engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged .
If starting capab ility is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in 3
minutes.
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged . This happens mostly
when little energy is being generated and a great dea l consumed and
the battery's state of charge is not optimal.
T o bring the energy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy . If you notice, for example, that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off . These systems w ill be ava ilable again as soon as
the energy balance has been restored.
You will also notice that engine idle speed has been increased
slightly. This is normal and not a cause for concern . By increasing
engine idle speed the additional energy required is generated and the
battery is charged. •
