Power child safety lock for the rear doors t
The power child safety lock prevents the rear doors from
being opened from the inside.
F ig. 38 Section from
driver's door: controls
The rear doors are equipped with a power child safety lock . It
is operated with the two safety buttons(!) in the driver's door
~ fig. 38.
-Press the left and/or right safety button to disable the
rear power window(s) and prevent the respective rear door
from being opened from the ins ide . The LED in the button
will light up when the child safety lock is turned
o n .
- Press the illuminated button again to turn the child safety
features
off.
When the child safety lock is activated, the interior door opening
lever is inope ra tive; the door can only be opened from the o utside. In
addition, the window regulator for that door is also inoperative when
the chi ld safety lock is activated .
If the child safety lock has been activated on both the left and r ight
side, then the following features are switched off : the buttons for the
inter io r lights, the sun blind* in the rea r window and the buttons for
the power sun blinds* in the side windows. In addition to this, the
rear climate contro l* is set to the
PAS SIVE mode. Th is means that the
climate controls in the front adjust the heating and ventilat ion in the
rear of the vehicle=>

The Convenience key features is a keyless system which gives you the
possibility to lock and un lock your veh icle, as well as to start the
eng ine without having to use your key.
It does not matte r if you have your key in your jacket pocket or in your
briefcase . As soon as you get within a certain distance to the vehicle,
the system senses that your are approaching, it makes a quick check

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
Reduced visibility is dangerous and can cause accidents.
• For safe driving it is very important that all windows be free of
ice, snow and condensation.
• Completely familiarize yourself with the proper use and func­
tion of the heating and ventilation system and especially how to
defog and defrost the windows.
• Never use the windshield wiper/washer system in freezing
weather until you have warmed the windshield first, using the
heating and ventilation sy stem. The washer solution may freeze
on the windshield and reduce visibility.

ECON
The ECON mode helps to save fuel .
The air conditioning is turned off in ECON mode. "ECON" means
" E conomy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified .
If the vehicle inter ior becomes too hot or if the windows fog up, ECON
mode should be turned off. As soon as the
( AUTO] button in the air
conditioning controls is pressed, the system automatically leaves the
ECON mode, and the air conditioning compressor is turned on
again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode .
We recommend that you always keep automat ic air recirculat ion ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the facto ry-insta lled pollutant fi lter or whe ther it is
necessary to switch to air recirculation. With heavy concentrations of
pollutants, the air conditioning system is switched a utomat ically to
recirculation mode and the supply of outside air is blocked . As soon .,.

Overheating of brakes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads, the EDL cuts out temporarily . The
veh icle remains operat ional and beh aves in the same way as a vehicle
without EDL .
As soon as the brake has coo led down, EDL switches on again auto­
matically .
& WARNING
• When a ccelerating on slippery surfaces, such as on ice or snow,
alw ay s be careful when depre ssing the a ccelerator pedal. E ven
with the EDL working, the drive wheel s can spin and reduce your
ability to control your car . Risk of crash !
• The in creased safety afforded by EDL does not mean that you
can take safety ri sks. Always adapt your driving st yle to the road
condition s and traffic situation .
fi Tips
If a fault occurs i n the ABS, the EDL is also no t fu nct ion ing . This is
indicated by the ABS warning light~
page 19. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulati on System prevents the driven
wheels from spinning when the car is a ccel erating.
General notes
T he Anti-S lip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the veh icle starts up and acceler­
ates , the wheels are p reve nted from sp inning by adjust ing the eng ine
powe r to match t he amo unt of grip avai lab le from the road s urface.
How the system works
ASR perfo rms au toma tica lly, i .e . witho ut the drive r's in tervent ion .
With the aid of the A BS sensors~
page 256, ASR monitors the speed
of the driven wheels . If the wheels start to spin, the engine powe r is
reduced automat ically u nti l the t ires find enough gr ip to lock onto
the road s urface. The system is active across the entire speed range.
Th e ASR wor ks in con ju nction with the A BS .
If a m alfu nction sho uld
occur in the ABS, the ASR w ill also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety ri sks . Always adapt your driving style to the road
condit ions and traffic situation.
[ i ] Tips
To ensure that the ASR works prope rly, all four wheels must be fitted
w ith ident ic a l ti res Any differences in rollin g radius of the tires can
cause the system to reduce engine power when t his is not desired .

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. •
Driver notification in the instrument
cluster display
If the battery's state of charge is not in the optimal range, this driver
no tifi cation appears in the instrument cluster display:
Low battery charge: battery will be charged while driving ~
