Climate controls
Controls
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 68 Climate contro ls
We recommend the following sett ing :
> Rotate the knob ¢ fig. 68 @to the right to
switch on the air conditioning .
> Set the temperature to 72 °F (22 °() .
> Press the !AUTO I ¢ fig . 68 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . This setting should there­
fore only be changed when persona l comfort
l eve ls or ce rtain circumstances requi re it .
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehumidifies and coo ls
the air ins ide the veh icle.
The climate controls automatically maintain a temperature once it has been set . The tem­
perat ure of the air from the vents, fan speed
(air vol ume) and ai r d ist ribution are also auto­
mat ical ly adjusted . The system also takes into
account strong s unshine so that manua l ad­
justment is not necessary. So in almost all cases,
a ut om at ic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year ¢
page 69.
Please not e:
In cooling mode , relative humidity in the inte­
rior is reduced . This prevents the w indows
from fogg ing up.
When relative hum idity and temperatures
outside are high ,
conden sati on can drip from
the a ir condition ing evaporator and form a
pool of water under the vehicle. This is normal
and not an ind ication of a leak!
When outs ide temperatures are low, the fan
does not switch to a higher speed until the
coolant has reached an adequate tempera ­
tu re, with the exception of the defrost set­
t ing.
When accelerating at wide-open throttle, the air conditioning compressor is temporarily
switched off to ma intain full engine power .
In order to ensure engine cooling under ex­
treme engine loads, the compressor is switch­ ed off if coolant temperatures climb too high.
Funct ions are set by turning the rotary knob
or switched on and off by tapp ing the buttons.

70 Warm and cold
the air conditioning is on as short as possible,
you should do the fo llowing:
... If you wo uld like to save f uel , sw itch the air
cond ition ing off .
... If you open the windows whi le driving,
switch the air conditioning off .
... If the vehicle is extremely hot due to the
heat of the sun, brief ly open doors and win­
dows.
@) For the sake of the environment
When you save fuel, you reduce emissions
from the vehicle.
Rear window defogger
The rear window defogger clears the rear win­
dow of condensation .
... Press the [iii) button c:> page 66, fig. 68 to
turn the rear window defogger on and off.
The rear window defogger works only when
the eng ine is running. The indicator light in
the button illuminates when t he rear window
defogger is turned on.
The rear window defogger is switched off au­
tomatically after 10 to 20 minutes, depend­ ing on the outside temperature.
At very low outside temperatures, the rear
window defogger can be switched on continu ­
ously by pushing the
[iii) button for more than
2 seconds. This remains stored unt il the igni­
tion is sw itched off. A rear window defogger
that was switched on also remains stored for
15 minutes after the ignition is switched off .
If the engine is restarted within these 15 mi­
nutes, the rear window defogger is act ivated
for 10 to 20 minutes, depend ing on outs ide
temperature . With a vehicle that is parked for
a short time, the rear w indow defogge r does
not need to be ma nually activated again.
@, For the sake of the environment
As soon as the rear window is clear, you
should switch the rear window defogger off.
The reduced power consumption has a
beneficial effect on fuel consumption .
Heated seats
Applies to vehicles : w ith hea ted seats
The seat cushion and the seatback of the
front seats can be heated electrically.
... Press the heated seats button I-J + I
c:> page 66, fig. 68 to set the level of heating
desired.
The range of cont ro ls goes from 1 to 3. Th e
heat setting selected is shown by LEDs above
the button.
A WARNING
-Indiv iduals with reduced sens itivity to pain
or temperature could develop burns when
using the seat heating function . To reduce
the r isk of injury, these ind ividuals should
not use seat heating.
~ Note
To avoid damage to the heating elements
in the seats, do not kneel on the seats or
place heavy loads on a small area of the
seat.

Kick-down feature
Applies to vehicles: with S tron ic
The kick-down feature allows maximum ac­
celeration .
If you depress the accelerator pedal fully be­
yond the full-throttle position, the transmis­ sion automatically downshifts one gear, de ­
pending on vehicle speed and engine rpm . The
upsh ift into the next higher gear takes place
as soon as the max imum specified engine
speed is reached.
A WARNING
Please note that the drive wheels can spin
if the kick-down is used on a smooth s lip­
pery road - risk of skidding!
Launch Control Program
Applies to vehicles: with S tron ic
The Launch Control Program permits maxi ­
mum acceleration .
In o rder to u se La unch Control, the ASR (An ti­
Slip Reg ulation) mus t be d is a b led. When ASR
is disab led, the ESC wa rning/ind icator light
IJ
in the inst rument cluster illuminates . So that
L aunch Cont ro l can be used, the engine must
be at operating temperature and the steer ing
wheel must not be turned.
~ With the eng ine running , brief ly press the
ESC button . The message "Stabilization pro­
gram off" or "Sport control Warning! Re­
stricted stability" in the driver information

~ Sh ift the gear lever to "S" or the tiptronic ®
pos it ion .
~ Step on the b ra ke peda l w ith your left foot
and keep the bra ke peda l fully depressed for
at leas t one second .
~ With your right foot, step on the acce lera ­
tor to the w ide-open throttle position o r
K ickdown . The engine speed settles at about
3,200 rpm.
~ Take your left foot off the brake .
Transm iss ion 85
A WARNING
-Always adapt your dr iving to the traffic
f low.
- Onl y use Launch Control when road and
traffic cond itions allow it and other dr iv­
ers will not be endangered or annoyed by
your driving and th e acce le rat ion of the
veh icle.
- Ma ke sure that ESC remains enab led.
With the ESC disab led, th e vehicle could
b ra ke away, part icularly on a s lick and
slippe ry ro ad - ris k of skid ding!
- Once acceleration is fi nished, switch AS R
on agai n by br iefly pushing t he ESC bu t­
ton.
Back-up program
Applies to vehicles: with S tronic
In the event of a system malfunction, there is
a back-up program.
In the event of system ma lfunction, the auto ­
matic transmission switches to the fai l-safe
mode. All of t he se lector lever position d is­
plays for the au tomatic tra nsmission a re hi gh­
li gh ted wi th a light b ackgro und in t he i nstr u­
ment cluster d isp lay . In some cases you can ­
not use reverse gea r any more.
If the t ransmission swi tches to fail-safe
mode, yo u should t ake the ve hicle to an au­
t horized Audi dea le rship as soon as possib le
to have the condition corrected.
Clutch is overheating
Applies to vehicles: with S tronic
• Clutch is overheating ! Please stop veh i­
cle!
If the symbols a re i lluminated, the clutch is
ove rheating a nd could be damaged if you con­
tin ue to drive. Stop the vehicle and a llow the
transmission to cool with the se lector lever in
the P posit ion while the engine runs at idle. If
the warn ing does not turn off, do not continue
dr iv ing . See your author ized A udi dealer or
i,..

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -loc k brak ing s ystem (ABS )
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is helping you to brake the vehicle.
B rake ass is t system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Elect ronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot ove rcome
t he laws of physics. This is espec ia lly im ­
portant on slippery or wet roads.
If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligen t technolog y 151
to take risks. Doing so will increase the
risk of a loss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot preven t coll i­
sions.
- Always ac celera te with spe cial care on
even, smooth s urfaces su ch as those th at
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems described are working.
-If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢ page 18,

than is being generated and ensures an opti­mal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
li mited.
- If starting ab ility is threatened, you are
i nformed by a warning
¢ page 157,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant e lectrica l energy is re­
quired, but only a litt le is generated. It is also
cr itical if the engine is not run ning and electri­
cal components are turned on. In th is in­
stance energy is being consumed but non e is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat ­
in g 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 compo­
nents are gradually cut back or switched off.
This reduces energy consumption and mai n­
tains sta rting capab ility over a longer per iod.
Take into consideration that when you un lock
your ve hicle, some co nvenience functions,
such as the remote key or power seat adjust ­
ment, may not be available . The convenience
f u nctions w ill be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis­
charged .
Intellig ent technolog y 157
If starting capability is jeo pardi zed d ue to en ­
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although e lectrical energy is generated when
the ve hicl e is being driven, t he battery can be­
c ome disc harged. This happe ns mostly when
li ttle energy is being generated and a g reat
deal consumed and t he battery's sta te of
c h arge is not optimal.
T o b ring the energy b alance b ack into equili ­
br ium, consumers which requ ire espe cially
la rge amounts of energy a re temporari ly cut
back or switched off . Heating systems in pa r­
ticu lar require a great deal of energy. If yo u
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for conce rn . By i ncreas ing eng ine id le
speed the additional energy r equired is gene r­
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:
(•) Low battery charge: battery will be
charged while driving
T his no tificat ion reminds yo u that the star ting
capability of the engine may be lim ited . As
soon as you sta rt dr iving again, the battery
will be recharged and the not ificat ion w ill go

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 con tinue 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 Wa rranty
&
Ma intenan ce 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 exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f 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 persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 161
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give yo u 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.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, 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.
Acce lerat ing gently reduces fue l 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 il l
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

162 Driving and en vironm ent
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 traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic lights that have
l ong wa its on red . Turning the engine off fo r
just 30-40 seconds saves more fue l than is
burned starti ng 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 nox ious em issions 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 whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights shou ld 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
Audi dealer helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ab ility to
hold its value, it also affects
fuel con sump­
tion .
Check you r oil ea ch time you fill you r tan k.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
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 sh ie lds, switches, ignit ion w ires,
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 w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road, the mileage improves
to 12 MPG (20 l/100 km). It w ill take the
