Climate controls
Controls
The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 79 Climate contro ls
We recommend the following sett ing :
> Rotate the knob 9 fig. 79 @ to the right to
switch on the air conditioning .
> Set the temperature to 72 °F (22 °().
> Press the !AUTO !~ fig. 79 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 personal comfort
l eve ls or certain circumstances require it.
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehum idifies and coo ls
the air inside the vehicle.
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 air distribution are also auto­
matically adjusted . The system also takes into
account strong sunshine so that manua l ad­
justment is not necessary. So in almost all
cases,
automatic mode offers the best condi­
tions for the comfort of the occupants at all
times of the year

Please note :
In cooling mode , relative humidity in the inte­
rior is reduced . This prevents the windows
from fogg ing up.
When relative humidity and temperatures outside are high ,
condensation 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 outside 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 in g.
When accelerating at wide-open throttle, the air conditioning compressor is temporarily
switched off to maintain 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.
Functions are set by turning the rotary knob
or switched on and off by tapp ing the buttons.

Pollutant filt er
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
dust or po llen) are greatly reduced or stop­
ped. The air is also filtered in recirculation
mode.
The pollutant filter element must be changed
according to the intervals specified in the
maintenance schedule so that the air condi­
tioning system's performance is not adversely
affected .
If the fi lter's effectiveness is weakened by
driving the vehicle in areas with heavily pollut­
ed outside air, the filter element should also
be changed in between the listed services.
A WARNING
For safety reasons, it is important that all
w indows are free of ice, snow, and conden­
sa tion. Only then is good visib ility ensured.
Please fam iliarize yourse lf w ith the correct
operation of the air conditioning and how
to de humidify/defrost the windows .
(D Note
-If yo u suspect that the clima te controls
have been damaged, switch the system
Warm and c old 69
off to avoid damaging it, and have it in ­
spected by an authorized Audi dealer .
- Audi climate control system repairs re ­
quire special expertise and the proper
tools . You should contact an authorized
Audi dealer in the event of malfunctions.
(D Tips
- To avoid adversely affecting heating and
cooling performance and to prevent con­
densation on the windows, the air intake
in front of the windshield must be free of
ice, snow, and leaves.
- The air coming from the vents and circu­
lat ing through the entire interior is ex­
tracted through the out let slots in the
side pane ls in t he luggage compartment.
Make sure that the outlet slots are not
covered by clothing, etc.
- Climate control works most effectively if
the windows are closed. Howeve r, if the
inter io r of a par ked vehicle is ext reme ly
hot from the sun's rays, briefly open ing
t he windows can speed up the cooling
process .

The rear window defogger works only when
the engine is running. The indicator light i n
the button illum inates when the rear window
defogge r is turned on .
The rear window defogger is switched off au­
tomatically after approx . 10 minutes.
@ For the sake of the environment
As soon as the rear window is clear, yo u
should switch the rear window defogger
off . The reduced power consumption has a
beneficial effect on f uel consumption.
Heated seats~
App lies to vehicles: with heated seats
The seat cushion and the seotbock of the
front seats con be heated electrically.
.,. Press the heated seats button I-J + I
¢ page 68, fig. 79 to set the level of heating
desired .
The range of controls goes from 1 to 3. The heat se tting se lected is shown by LEDs above
the button .
& WARNING
Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these individuals should
not use seat heat ing .
To avo id damage to the heating e lements
in the seats, do not kneel on the seats or
place heavy loads on a small area of the
seat .
Using the climate controls economically
Economical use of the climate controls helps
to save fuel .
When climate control is working in coo ling
mode, engine performance is reduced and
fuel consumption is affected . To keep the time the air cond
itioning is on as short as possible,
you should do the following:
.,. If you would like to save fuel, switch the air
conditioning off .
.,. If you open the windows while driving,
switch the air conditioning off .
.,. If the veh icle is extreme ly hot due to the
heat of the sun, br iefly open doors and w in­
dows .
@ For the sake of the environment
When yo u save fuel, you reduce emissions
from the vehicle.

_& WARNING
-Always adapt your driving to the traffic
flow.
- Only use Launch Control when road and
traffic conditions allow it and other driv­
ers will not be endangered or annoyed by
your driving and the acceleration of the
vehicle .
- Make sure that ESC remains enabled .
With the ESC disabled, the veh icle could
brake away, particularly on a slick and
slippery road -risk of skidding!
- Once acce lerat ion is finished, switch ASR
on again by briefly pushing the ESC but­
ton.
@ Tips
- The transm ission temperature may in­
crease significantly after using the
Launch Control Program. If that hap­
pens, the program may not be available
for a few minutes. I t will be availab le
again after a coo l-down period.
- When accelerating using the Launch
Control program, all vehicle parts are
subject to heavy loads . This can result in
increased wear.
Back-up program
Applies to vehicles: with S tronic
In the event of a system malfunction, there is
a back-up program.
I n the event of system mal func tion, the auto­
matic transmission switches to the fail-safe
mode. A ll of the selector lever position dis­
plays for the automatic transmission are high­
lighted with a light background in the instru­
ment cluster display . In some cases you can­
not use reverse gear any more .
If the transmission switches to fail-safe mode, you should take the vehicle to an au­
thorized Audi dealership as soon as possible
to have the condition corrected.
Transmission 87
Clutch is overheating
Applies to vehicles: with S tronic
• Clutch is overheating! Please stop vehi­
cle!
If the symbols are illuminated, the clutch is
overheating and could be damaged if you con­
tinue 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 warning does not turn off, do not continue
driving. See your authorized A udi dealer or
qualified repair facility for assistance. Other­
wise serious transmission damage could re­
sult. Once the indicator light has turned off,
drive to your authorized Audi dealer or quali ­
fied repa ir facility immed iately to have the
malfunction corrected.
Selector lever emergency release
Applies to vehicles: wi th S tronic
If the vehicle's power supply fails, the selec ­
tor lever can be released in an emergency.

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-lock braking system (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 pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist 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 si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (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.
Electronic differential 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 overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
your speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 143
to take risks. Doing so will increase the
risk of a lo ss 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, especially 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 prevent colli­
sions.
- Always accelerate with special care on
even, smooth surfaces such as those that
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 si zes 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¢

148 Intelligent technology
Battery diagnosi s
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is standing.
With the ignition switched off, it controls the
energy supply to the various electrical compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
al components. It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti ­
mal state of charge for the battery .
(D 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 149,
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 cold time
of year. Abundant electrical energy is re­
quired, but only a little is generated.
It is also
critical if the engine is not running and electri- cal components are turned on.
In this in­
stance energy is being consumed but none is
being generated.
It is in precisely these situations that you will
notice energy management actively regulat­
ing 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 main­
tains starting capability over a longer period.
Take into consideration that when you unlock
your vehicle, some convenience functions ,
such as the remote key or power seat adjust ­
ment, may not be available. The convenience
functions will be available again when you
turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off, the battery is being dis­
charged.
If starting capability is jeopardized due to en­
ergy consumption, a message appears in the
driver information display.
You have to start the engine to charge the
battery.
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­
brium, consumers which require especially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular 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 .,.

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 otherw ise 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 intained properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper main tenance 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
E ven when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfur -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 it h lead-free super
grade gasoline.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized dealer . T hey ca n ad­
vise you on necessary precautions e.g . corro­
sion prevent ion, ma intenance and storage.

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, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consumption on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac­
celerating.
Avoid unnecessary acce lerating and braking .
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff 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 maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
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 traffic 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 engine 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 whi le the engine
is sti ll warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over-
Driving and environment 153
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
Audi dealer helps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained 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 control system and could 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 .
