Deactivating
- Turn t he light swi tch to position 0 .
In the switch position AUTO the automatic head -and taillight
control
i s activated . The correspo nding symbol on the light swi tch
is lit .
With automatic head lights, the high -beam function is also avai lab le,
bu t with one restrict io n: If you have not switched the h ig h beams
back to low beams during automatic headlight operation (for
example, afte r driving through a tun nel), on ly the low beams come
on the next time automatic headlights are switched on. To use the
h igh beams, you first have to pull the high beam lever back and then
push the lever forward again. Parking
lights, headlights, fog lights and the rear fog light can be
swi tch ed on manually using the ligh t switch ~
page 69.
Light sensors located in the inside mirror housing and stem
constantly check the light conditions surrounding the vehicle. If
am bie nt brightness falls below a facto ry set value (e.g. wh en driv ing
into a tunnel), the head -and tai llights inc luding the license p late
ill um inat ion are automatica lly t urn ed on. When ambient br ightness
increases again, the external lights are turned off again~&.
Light sens or malfunction
If there is a light sensor malfunct ion, the symbol comes on in the
display . For sa fety reasons, the low beams are turned on perma­
nent ly with the switch in
AUTO . However, you can continue to turn
the lights on and o ff using the light swi tch . Have the light sensor
checked as soon as possible at a dealership .
& WARNING
• Automatic head- and taillight control is only intended to ass ist
the driver . This feature doe s not relieve the dr iver of hi s re spon si­
bil ity to check the headlights and to turn them on manually
ac cording to the current light and vi sibility conditions. For
e x ample , fog and rain cannot be detected by the light sensors .
Con sequently , always switch the headlights
io on under thes e
weather conditions and when driving
in the dark .
• Crashe s can happen when you cannot see the road ahead and
when you cannot be seen by other motor ists .
• Alway s turn on the headlights so that you can see ahead and
so that others can see your car from the ba ck .
[ i ] Tips
• I n the AUTO mode, the low beams are turned off when the igni ­
t ion is turned o ff. The remaining lights are turned o ff when the key
is taken out of the ignition lock. _.,

• Do not attach stickers to the windshie ld in front of the sensors as
this can disable the automatic head -and tail light control and the
automatic glare -dimming of the rearview mirror(s) .
• Always o bserve the spec ific loca l regu la tions f or your area when
to use your lights .
• I n the event of a light sensor mal function, the d river informa tion
display will show the symbol . If a light sensor malfunct ion is indi ­
ca te d , you must use the ligh t switch to turn the low beams on and
off .•

Coming home situation
In
darkness, the activated system will turn on the headlights, side
marker lights , rear side marker lights , tail lights, and rear license
plate light as soon as the driver's door is opened from inside.
As long as one of the doors or the rear lid remains open, the set of
external lights will keep burning for about four minutes maximum.
To provide light for departure, the set of vehicle lights will keep
burning for about another 30 seconds after all doors and the rear lid
have been closed.
The factory-set time of 30 seconds until the lights are switched off can be adjusted if you prefer a longer or shorter duration. Have the
adjustment done by your authorized Audi dealer or a qualified work­
shop. The system can be adjusted to keep the lights burning for a
maximum of 60 seconds.
Leaving home situation
As soon as the vehicle is unlocked by pressing the
ti button on your
remot e control, the set of external l ights is switched on .
The external lights are switched off as soon as the driver's door is
opened from outside . Even if you had the system readjusted to keep
the lights burning for an extended time for coming home, the
external lights will be turned off if you do not open the driver's door
within 60 seconds after unlocking. See chapter "Opening and
Closing" in your Owner's Manual. If the lights are switched off
before you reach the driver's door, press the
a button once more to
turn them on again.
[ i] Tips
• Do not attach any stickers to the windshield in front of the two
light sensors, as this would interfere with both the automatic oper­
ation of the headlights and the automatic dimming of the inside
mirror(s). • If
the vehicle is remotely unlocked and locked three times in
succession, leaving home will not turn on the lights a fourth time to
safeguard the battery and lights.
• If you wish to use the coming home/leaving home function regu­
larly, you can leave it activated at all times without risking perma­
nent strain on the electrical system. As the system is controlled by
light sensors, it will only be energized in darkness .
• Frequent use of the coming home/leaving home function for
approaching and departing a vehicle parked in the dark will strain
the battery. This applies particularly if only short distances are
driven between stops . Occasionally drive longer distances to make
sure the battery is recharged sufficiently.
• If the fog lights have been switched on by the coming
home/leaving home function, they will always be switched off when
you switch on the ignition. •

0 Note
The instrument c luster and center console illumination (gauges and
needles) comes on when you switch on the igni tion and the
vehicle
headlights are off .
Be aware of the followin g difference be tween
models built to US o r Canadian specifications :
• USA models : illumination of the in strument 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 illum ination 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 d river , to
s witch on the headlight s before it gets too dark.
• Canada models : instrument panel illum ination will stay br ight
regardle ss of the inten sity of ambient light . Always be aware of
c hanges in outside light conditions while you are driving . Respond
in time to fading dayli ght by turning the light switch to position
iD
(or "AUTO" if your car is equipped with this feature) to turn on your
headlights. •
Bi-Xenon headlights*
Afte r starting the engi ne, the b i- xeno n headlights are au tomatical ly
adjusted to the load and angle of the vehic le (for example, during
acce lera tion and braking). This prevents oncoming traffi c from
experiencing unnecessary headlight g lare from your bi -xenon head ­
lig hts .

Service position The wiper blades can be changed more easily in the
service position .
Fig . 73 Wiper lever
It is only possible to change wiper blades if you move the
w iper arms to the service position. On vehicles with the
Driver Information System , the wiper blades can only be
moved to the service or parked position via t he menu
display =>
page 27. In order to use the windshield wipers,
the hood must be completely closed.
Moving wiper blades to the service position
-When there is a risk of frost, make sure that the wiper
blades are not frozen to the windshield .
- Switch the ignition on .
- Switch the ignition off again and move the wiper lever
~ fig. 73 from position Oto 1 within 10 seconds . The
wiper arms now move into the field of view in the wind ­
shie ld.
Moving wiper blades to park position
-Make certain that the wiper arms are lying against the
windshield .
- Switch the ignition on and move the wiper lever~ fig . 73
from position Oto
1. The w iper arms w ill move back to the
park position.
I t is much easier to chang e wiper blad es if you mov e th e wiper arms
to the service position. You wil l also avoid paint damage to the hood
when working on the wip ers when they are in the service position .
0 Note
Never drive your vehicle when the windshield wiper arms are in the
service position and pulled away from the windshield . When you
drive faster than 4 mph (6 km/h) , the wiper arms automatica lly
return back to the park position and could cause paint damage to
the engine hood!
[ i ] Tips
• You can also turn on the service position, for example, if you
want to protect the windshield from icing by using a cover.
• The service position moves to
off automatically when you
operate the windshield wiper lever, or speed exceeds 4 mph
(6 km/hl. •

Acoustic parking system
A pplies to veh ic les : wit h 4 -ch anne l a cou stic park ass is t
Rear acoustic park assist
Acoustic park assist gives a warning a bout o bstacles
behind the vehicle.
Description
The rear acoustic park assist (4 -channel acoustic park assist) deter ­
mines the d istance of the vehic le from an obstac le using u ltrasonic
sensors. The sensors are in the rear bumper. The volume and the
pitch of the chimes can be adjusted through the menu display
=> page 27.
The range at which the sensors start to m easure is about :
To the side
Center rear
Acti v atio n
2 feet (0 .60 m)
5 feet (1.60 ml
The pa rking assist is activated when rever se ge ar is engaged . A brief
tone confirms that the system is activated .
Backing up
Distance warning when backing up starts when an obstacle is
detec ted in the range of the park ass ist system . As the distance
decreases, the time interval between the aud ible tones becomes
shorter .
When the distance is less than 1 foot (0.30 m) , the tone becomes
continuous . At this point you should stop backing up.
Please note that low objects a lready signalled by a warning can
disappear from the sys tem's detection range and wil l not continue
t o be signa lled . ..,

Pote nt ial malf un cti ons
If a warning buzzer sounds for a few seconds when the ign ition is
switched on, there is a system malfunction with the acoustic park
assist. If the malfunction persists until the ignition is switched off,
there will be no acoustic warning at the next attempt to activate the system. Have the problem corrected.
There is no confirmation tone when reverse gea r is engaged if there
is a system malfunction .
For the parking assist to operate, the sensors must be kept clean
and free of ice.

does not stop completely -the vehicle "creeps ".
• Do not ac celerate when you change the selector lever position
with the vehicle stationary and the engine running -risk of an acci ­
dent!
• Never place the selector lever
in the R or N position while the
vehicle is mov ing -risk of an accident !
• If you have to bring your vehicle to a stop while on an incline ,
keep the foot brake depressed all the way down so that the vehicle
does not start to roll backward. You should never hold the vehicle
using the clutch pedal if you are going to be stopped on an incline .
If you do , the clutch will start to slip when it overhe ats cau sed by
the constant overload . This is dangero us because if the vehicle
starts to roll backward , you could cause an accident. If the clutch
should start to slip , you will feel the vehicle "jerk" and the sele ctor
lever display will start blinking.
• Before driving down a steep slope , reduce your speed and shift
into a lower gear with "tiptronic ".
• Do not ride the brakes or apply the brake pedal too often or too
long. Constant braking causes the brakes to overheat and
substantially reduces braking performance , increases braking
di stance or cau ses complete failure of the brake system. •
