- Some of the equ ipment o r features
shown in the genera l ill ustrat ion may be
standard equ ipment on your vehi cle or
m ay be opt ional eq uipment depending
on your model. A lways ask your author­
ized Aud i dea le r i f you have a quest ion
about your vehicle .

dea lership.
Com ing home /leaving home function *
The function is switched on when the switch is
i n the AU TO* position and the function is
shown as active in the driver info rmation sys­
tem .
The
co ming h om e function illuminates the
a rea around the veh icle when the ign it ion is
switched off and the driver 's door is opened.
The length of time the lights remain on can be set in the menu display
( Illumination > Exte­
r io r light s> coming hom e).
The leav ing home function illuminates the
area around the vehicle when unlock ing it.
A WARNING
- Never use dayt ime running lights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dark. Always switch on
the low beams at dusk or when it is dark.
- Automatic headlights are only intended
to assist the dr iver . They do not relieve
the driver of his responsibility to check
the headlights and to tu rn them on man­
ually according to the current light and
visibili ty cond itions. Fo r example, fog
and rain cannot be detected by the light
sensors . So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
io.
- Crashes can happen when yo u cannot see
the road ahead and when you cannot be seen by other motorists .
- Always turn on the headlights so that
you can see ahead and so tha t others
can see yo ur car from the bac k.
- With the switch in
AUTO front fog lights
ca nnot be t urned on in addition .
- The light sensor fo r headlight contro l is
l ocated in the rear view m irror mount .
Do no t apply any stickers to the w ind- shield in this area to prevent malfunc
­
tions or fa ilures.
- Some exter io r light ing funct ions can be
adjusted in the driver informat ion sys­
tem
~ page 2 7.
- If you remove the ignition from the igni ­
tion lock while the headlights are still
on, a buzzer will so und as long as the
dr iver's door is open to rem ind you to
turn off the lights.
- Always observe the specif ic loca l regula­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam funct ion is also available, but wit h
one restrict ion: If you have not switched
the high beams back to low beams dur­
ing automatic headlight operation (fo r
example, after d riving through a tunnel) ,
only the low beams come on the nex t
t ime au tomati c headlights are swi tc h ed
on. To use the high beams, you first have
to pull the high beam lever back and
then push the lever fo rward again.
- In cool or damp weather , the inside of
the headlights, turn signals and tail lights can fog over due to the tempera­
ture difference between the inside and
outside. They w ill clear shortly after
switching them on. This does not affect
the se rv ice life of the lighting .
- Frequent use of the coming home/leav ­
ing home function for app roach ing and
depa rting a vehicle parked in the da rk
w ill strain the battery . Thi s ap plies pa r­
tic ular ly if only short distances a re d riven
between stops . Occasionally drive longer
dis tances to make sure the battery is re ­
charged sufficiently.

(D Note
The instrument cluster and center console
ill umination (gauges and need les) comes
on when you switch on the ignition and the
vehicle headlights are off . Be aware of the
follow ing difference between models built
to US or Canadian specifications:
-USA models: illumination of the instru­
ment cluster (gauges and needles),
dash and center console around the
gearshift lever is controlled by a light
sensor located in the instrument panel.
The instrument panel illumination will
automatically become dimmer as the
daylight fades away and eventually will
go out completely when outside light is
very low. This is to remind you, the driv­
er, to switch on the headlights before it
gets too dark.
- Canada models: instrument panel illu·
mination will stay bright regardless of
the intensity of ambient light. Always be aware of changes in outside light
conditions while you are driving. Re­
spond in time to fading daylight by
turning the light switch to position
gD
(or "AUTO " if your car is equipp ed with
th is feature)
to turn on your headlights.

Warm and cold Climate controls
Description
The air conditioner is fully automatic and is
designed to maintain a comfortable and uni­
form climate inside the vehicle .
We recommend the following settings:
... Se lect and set a temperature between 64 °F
(+ 22 °C) and 84 °F (+28 °C).
... Press the
!AU TO ! button.
With this setting, you attain maximum com­
fort 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 distribu­
tion are automatica lly regulated to achieve
and maintain the desired passenger compart­
ment temperature as quickly as possib le.
The system automatically compensates for
changes in the outside temperature and for
the intensity of the sunlight entering the vehi­
cle. We recommend you use the
Automatic
mode c> page 81 for year-round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity
in the vehicle. This also p revent the windows
from fogging up .
When the outside temperature is high and the
air is very hum id,
condensation from the
evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
If the outside temperature is low, the fan nor­
mally only switches to a h igher speed once
the engine coolant has warmed up sufficient ­
ly.
Warm and cold 79
T he air conditioner temporari ly switches off
when you drive off from a standstill using full
throttle to save engine power.
T he compressor also switches off if the cool­
ant temperature is too high so that the engine
can be adequately cooled under extreme
l oads.
Air pollutants filter
T he air pollutants filter (a combined particle
filter and activated charcoa l filter) reduces or
eliminates outside air pollution (dust, or pol­
l en) from entering the vehicle .
T he air pollutants filter must be changed at
the interva ls specified in yo ur Warranty
&
Maintenance booklet, so that the air condi ­
tioner 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 Ad­
visor for advice.
Energy management
To prevent the battery from being discharged
and to restore the ba lance of energy, compo­
nents which require large amounts of energy
are temporarily cut back or switched off c> page 167. Heating systems in particular re­
quire a great deal of energy. If you notice, for
example, that the rear window heater is not
heating, then it has been temporarily cut back
o r switched off by
energy management.
These systems are available again as soon as
the energy balance has been restored.
_& 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 con-
densation.
- Fully familiarize yourself with the proper
use and function of the heating and ven­
tilation system and especia lly how to de­
fog and defrost the windows.

-Do not clean the gri lle with a vacuum clean­
er, otherwise the sensors cou ld be damaged .

A WARNING
- Always pay attention to traffic even when
the cruise control is switched on . You are
always responsible for your speed and
the distance between yo ur vehicle and
othe r vehicles .
- For safety reasons, the c ruise control
sho uld not be used in the city, in stop­
and -go traff ic, on twist ing roads an d
when ro ad conditions are poo r (such as ice,
fog, gravel, heavy rain and hydro­
plan ing) -risk of accident.
- Turn off the cruise contro l temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise co ntrol not to brake. This is
because the cruise control is over ridden
by the dr ive r's acceleration.
(D Tips
- Veh icles with man ual transmiss ion: You
can attai n the set speed only if the cur­
rently engaged gear allows it and the en­
gine is not stressed . Sh ifting to a highe r
o r low er gea r promptly will a llow the en­
gine to r un smooth ly.
- The cr uise control can not mainta in a

lever pressed down, you will alter your speed
in S mph (10 km/h) increments.
You can also press t he accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however , you exceed yo ur saved speed by
5 mph (10 km/h) for longer than 5 minutes,
the cru ise control will turn off temporari ly.
T he symbo l will go out but the saved speed
will be reta ined .

182 Cleaning and protection
• Wipe the windows dry with a clean piece of
cloth or kitchen paper towel.
The best way to remove snow from w indows
and mir rors is to use a brush. Use a non -abra­
sive
pla stic ice scraper -better still, a spray
deicer -to remove
ic e from windows and mir­
rors.
The windows must not be cleaned with insect remover or wax since these can interfere with
the function of the windshield wiper blades (chatter).
O il, grease or silicone residue can be removed
with
glass cle aner or silicone remo ver. How­
ever, wax residue req uires the use of a specia l­
ly form ulated solvent. P lease contact your au­
thor ized Audi dealer for adv ice on safe prod­
ucts for wax removal.
Windows sho uld a lso be cleaned on the inside
at regular interva ls.
Never dry windows with the same chamois
that you use to dry painted s urfaces. Wax resi­
due on the chamois can impair vision thro ugh
the windows.
A WARNING
- The windshie ld m ust not be treated with
water-repellent materials. They can i n­
c rease glare under poor visib ility condi­
t ions such as wetness, darkness, o r whe n
the sun is low on the hori zon. In addi­
t io n, they ca n cause the wi ndshield wip ­
ers to chatter .
- Always read and heed all WARN INGS and
othe r inform ation
Qpage 178.
0 Note
- Never use warm or hot water to remove
s now and ice from windows a nd mirrors.
This cou ld cause the g lass to c ra ck .
- To prevent damage to the wi res of the
r ear defogger, do not place any adhesive
sticke rs o n the inside of t he rear w indow
ove r the wires.
- To he lp prevent d irt from s cratch ing the
window, always scrape i n a forwar d di- rec
tion -pushing the sc raper away from
you -never bac k and fort h.
Steel wheels
Applies to vehicles: with steel wheels (e .g. if refitted with
winter tires)
The wheels also have to be cleaned.
• Always include the hub caps and wheel rims
when wash ing your vehicle to remove road
dirt, sa lt sprays and brake dust .
If necessary, use a commercial whee l cleaner
to remove accumulated brake dust.
The wheel rims are easier to keep clean i f they
are regularly coated with liq uid wax.
Paint scra tches shou ld be touched up as soon
as possib le to prevent corrosion

Cast (light) alloy wheels
Applies to vehicles : with Cast alloy wheels
-
Cast (light) alloy wheels require special care.
• Wash the w heels with a sponge or hose
brush every other week .
• For deep cleaning afterwards, use on ly a
ded icated acid-free cast alloy wheel cleaner.
• Rub a coat of
liquid wa x onto the rims every
three month. Be sure to reach and treat all
parts of the rim .
To preserve the decorative appearance of the cast alloy w heels, some special care is neces ­
sary. In addition to road dirt and salt, brake dust is also co rrosive . If left on fo r too long,
brake d ust can cause pitting.
