Automatic recirculation
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 automatic recirculation ON to
prevent polluted outside air from entering the vehicle interior .
If the
air quality sensor located in the climate control system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the factory-installed pollutant filter or whether it is
necessary to switch to recirculation. With heavy concentrations of
pollutants, the climate control system is switched automatically to
recirculation mode and the supply of outside air is blocked . As soon
as the concentration of pollutants in the outside air drops, fresh air is
supplied to the vehicle interior again.
I n the event that the windows fog up during automatic recirculation ,
press the
l<:wl button immediately.
Under certain operating conditions, automatic recirculation is
switched off automatically. When outside temperatures are below
about
50 °F ( +10 °C), automatic recirculation is limited to
30 seconds. When outside temperatures are below about 30 °F (-
1 °C),
automatic recirculation is limited to 15 seconds.•

Intelligent t echnology
'-----------------------------------------------
Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors~
page 241. If a not iceab le
slip is detected at the wheels (e.g . on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
& WARNING
• When ac ce le rating on s lippery surfa ce s, su ch as on ic e or snow,
alwa ys be ca reful when depre ssing the accele rator pedal. Even
& W ARNING (continue d)
with the EDL working , the dri ve wheels c an spin and reduce your
ability to contr ol your car . Ri sk of cra sh!
• The inc reased s afety afforded by E DL does not me an that you
can take safety ri sks. Alwa ys adapt your d rivin g style to the r oad
conditions and t raffic situation .
[ i ] Tips
If a fau lt occurs in the ABS, the EDL is also not funct ion ing. This is
ind ic a ted by the ABS warn ing light ~
page 17. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Sl ip Regu lation System (ASR) is integrated in the electronic
stabiliza tion prog ram ( ESP) . When the ve hicle s tarts up and acceler­
ates, the wheels are prevented from sp inning by adjusting the engine
powe r to match the amount of g rip available from the road surface .
How the system works
ASR performs au toma tic a lly, i.e. witho ut the dr ive r's intervent ion.
With the aid of the ABS sensors~
page 241, ASR monitors the speed
of the driven wheels. If the whee ls start to spi n, eng ine torq ue is
reduced automatically unti l the tires find enough grip to lock onto
t he road s urface . The system is active across the en tire spee d range.
Th e ASR works in con ju nction with the ABS .
If a malfunction shou ld
occur in the ABS, the ASR wi ll also be out of action.
Act ivating
T he ESP is automatica lly activated when the engine is started and it
performs a self-test . You can act ivate a deact ivated ASR if required by _,,

Intelligent technology
'-------------------------------------------------
vi dual components. It regulates consumption, so that more electrical
energy 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 245, "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 severe ly taxed in short-distance driving, in city traffic
and during the cold 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 electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in prec ise ly these sit uations 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 sw itched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remo te key or power seat adjust­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
W ith 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 capability 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.
Th e warn ing indicates that the system will be turned off automati­
cally after 3 m inutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
driven, the battery can become discharged. This happens most ly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
T o br ing the ene rgy 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 will be ava ilable again as soon as
the energy ba lance 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
eng ine id le speed the additional energy required is generated and the
battery is charged. •

0 Note
• Before w inter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if yo u live in a region where
the winter is extremely cold.
If necessary, increase the proportion of
coolant additive to 60% .
• When adding coolant additive to your cooling system, remember :
- We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
engine coolant. Adding radiator repair flu id may adversely affect the
function and performance of your cooling system and cou ld result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance.
Fig. 208 Engine
co mpartment : Coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 275.
-Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank~ fig. 208 . With a cold engine, the coolant level
should be between the "MIN" and "MAX" markings. When
the engine is warm, the level may be slightly above the
"MAX" marking.
The locat io n of the coolant expansion tank can be seen in the engine
compartment illustration~
page 276.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check
System =>
page 34 will blink until you add coolant and the level has
been resto red to normal. Even though there is an electric coolant
level sensor, we still recommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system. In the event of
coolant loss, the cooling system should be inspected immediately by
your authorized Audi dealer. It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating .
& WARNING
The cooling system is under pressure and can get very hot. Reduce
the risk of scalding from hot coolant by following these steps.
• Turn off the engine and allow it to cool down.
