Economical use of the climate control system
helps save fuel.
When the climate contro l system is working in
coo ling mode, engine performance is reduced
and fuel consumption is affected. To keep the
time the cl imate control system is on as short
as possible, you should do the follow ing:
.. To save fuel, turn off cooling mode by press­
ing the AC button (indicator light goes out) .
.. In add ition, if you open the window or the
panoramic sliding/tilt ing sunroof* while
dr iv ing, turn off cooling mode by pressing
the AC button (indicator light goes out) .
.. If the vehicle is extremely hot due to the
heat of the sun, briefly open doors and win ­
dows.

Automatic recirculation
App lies to vehicles : with Del uxe a uto mat ic clima te con­
tro l pl us
An air quality sensor detects increased con­
centrations of pollutants in the outside air
and automatically switches to recirculation
mode.
We recommend that you always keep auto­
matic 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 dec ides whether the air pollut io n
can be reduced by the factory-installed pollu­
tant filter or w hether it is necessary to switc h
to recirculation. With heavy concentr ations of
po llutants, the climate control system is
switched automatica lly to recirc ulation mode
and the supply of o utside air is blocked . As
soon as the concentration of pollutants in the
outside air drops, fresh air is supplied to the
vehicle interior aga in .
In the event that the windows fog up during
automatic recircu lation, press the~ button
immediately .
Under certain operating conditions, automatic
recirculation is switched off automatically.
When outside temperatures are below about
SO °F (+10 °C), automatic recirculat ion is lim­
ited to 30 seconds. When outside tempera­
tures are be low about 30 °F (-1 °C), automatic
recirculation is lim ited to 15 seconds .
Synchronization
Applies to veh icles : with Del uxe a uto mat ic climate con ­

One climate control setting for all seats.
After Syn chronization is set to On , all of the
subsequent climate control settings (except
for seat heating *) for the driver are transfer-
red to the front passenger. ..,.

Synchronization is canceled when settings are
adjusted on the front passenger 's side .
Seat heating

I n pos ition 0, seat heating is turned off . The
con trol range is from 1 to 6.
Seat heating only functions when the seats
are loaded w ith body we ight. If a person is not
sitting on the front seats, seat heating should
be sw itched off to prevent unintentional hea t­
i ng of the seat surfaces.
_& WARNING
Individua ls with reduced sensitivity to pain
or tempe rat ure could develop b urns when
using the seat heating function. To reduce
the risk of inj ury, these individua ls should
not use the seat heati ng.
(D Note
To avoid damage to the heating elements
in the seats, do not kneel on the seats o r
place heavy loads on a small area of the
seat.
@ Tips
Please note that objects placed on the
seats may be detected. If these objects are

206 Intelligent technology
Driving off
When driving off, a lways be sure 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 .
Overheating of brakes
To prevent the disc b rake o f the bra ked wheel
from overheating if subjected to excessive l oads on this whee l, the EDL cuts out tempo­
rarily. The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL.
As soon as the brake has coo led down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the accelerator pedal. Even with the EDL working, the drive
wheels can spin and reduce your ability
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your dr iving style to
the road conditions and traffic situation.
0) Tips
If a fault occurs in the ABS, the EDL is also
not funct ion ing. Thi s is indicated by the
ABS war ning light ¢
page 16.
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 -Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
( E SP). When the vehicle starts up and acceler­
ates, the wheels are p revented from spinning
by adjusting the engine power to match the amount of grip available
from the road sur­
face.
How the system works
ASR performs automat ically, i .e. w ithout the
driver's intervention. With the aid of the ABS
sensors ¢
page 208, ASR monitors the speed
of the driven whee ls. If the whee ls start to
spin, engine torque is reduced automatica lly
until the tires find enough grip to lock onto
the road surface. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS . If
a malfunction should occur in the ABS, the
ASR will also be out of act ion.
Activating
T he ESP is automatica lly activated when the
engine is started and it performs a se lf-test .
You can activate a deactivated ASR if required by pressing the
¢ page 204, fig. 196 button.
When it is act ivated, the message
ESP/ASR
on
appears briefly in the display .
Deactivating
You can deactivate the ASR if required by
pressing the button (for less than 3 seconds)
¢
page 204, fig . 196. With the ASR deactivat­
ed, the ESP check light comes on, see
¢
page 15 . The message ASR off appears in
the d isplay as well. The ASR can be deact ivat­
ed at any speed.
The ASR s hould normally be activated all the
time . Only in certain exceptional situations
when some slip is desirable does it make
sense to deact ivate the ASR . Examples :
- when driving with tire cha ins
- when driving in deep snow or on loose
ground and
- when rocking the vehicle loose after it has
become stuck.
When the abnormal situation is
over, you
shou ld activate the ASR again .

212 Intelligent technology
If starting capability is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display:
Please start engine, otherwise system will
switch off in 3 minutes.
The warning ind icates that the system will be
turned off automatically 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 be ing driven, the battery can be­
come discharged . Thi s happens mostly when
little ene rgy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili­
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular require a great dea l of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will 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 increas ing engine idle
speed the add itiona l energy required is gener­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this is shown in the instrument cluster display
with the following driver message:
(•i Low battery charge : battery will be
charged while driving
This notif ication reminds you that the starting
capability of the engine may be limited. As
soon as you start driving again, the battery will
be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig ­
nition is turned on or whi le driving and it goes
out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig­
nition is turned on or whi le driving and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ability is
restricted . Have the battery checked as soon
as possible by an authorized Aud i dea ler or
qualified wo rkshop.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your personal driving style
- operating conditions
- technical lim itations
I f you anticipate what you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 215
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you ant icipate what is going to
happe n next, you will need to brake less and,
t hu s, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maxi -
mum speed .
Accelerat ing gently reduces fuel consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

216 Driving and environment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.,. Shut the engine off when you are not driv­
ing the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rail ­
road crossings, or at traff ic lights that have
l ong wa its on red. Turning the engine off for
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it runs properly and economically . The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances with a
cold engine .
The engine and cata lytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>
