22 Instruments and warning /indicator lights
When this symbo l ml illuminates, it means
that Adaptive Light is defective. Go to a quali­
fied workshop to have the headlights or the
control unit for the Adaptive L ight repaired.
@, o Light/rain sensor defective
App lies to vehicles: with automat ic headlights
The indicator light indicates a defect in the
automatic headlights/automatic wiper sys ­
tem .
If the symbo l illuminates, the light sensor has
failed. For safety reasons , the low beams are
turned on permanently with the switch in
AU­
TO . However, you can continue to turn the
lights on and off using the light switch . In the
case of a defect in the rain sensor , the w ind­
sh ield wiper lever functions are st ill available .
H ave the light/ra in sensor checked as soon as
possible at an authorized Audi dealer.
; Audi magnetic ride
Appl ies to vehicles: with Audi magnetic ride
The indicator light monitors vehicle damping.
The indicator light E illuminates when the ig­
nition is switched on as a function check.
@ Tips
If the indicator lamp illuminates while you
are driving, there is a malfunct ion in the
veh icle damping. The chass is should be in­
spected immediately by an authorized Au­
di dealer.
~ Diesel particulate filter clogged
Applies to vehicles: with diesel engine and diesel particu­
late fi lter
1/1 Particulate filter ! See owner's manual
If the indicator light II in the instrument
cluster comes on, the diesel particulate filter has become blocked with soot as the result of
constant short-distance driving. When the
II symbol illuminates, you can alter your
driving style to assist the filter self-clean ing
p rocess. Drive for approximately 15 minutes
in 4th or 5th gear (automatic transmission with the se
lector lever in the S position) at a
minimum speed of 37 mph (60 km/h) and an
engine speed of approx imately 2,000 RPM .
The temperature increase that will result from
this can burn off the soot in the filter. The
symbol will switch off when the cleaning is
successful. After a successful cleaning, there
is no need to bring the car to an authorized
dealer or qualified workshop because this is
part of normal vehicle operation .
If the symbol
DI does not switch off, see
your autho rized dea ler or other qualified
workshop to have the problem corrected .
As long as the indicator light
11!1 remains on
(diesel part iculate filte r plugged), you ca n ex­
pect increased fuel consumption and possibly
also a loss of engine performance.
For more information on the diesel particu­
late filter, refer to~
page 171 .
A WARNING ,__
Always adapt your speed to the current
weather, road and traffic conditions. You
should never disobey traffic laws in order
to follow driving recommendations .
¢ ¢Turn signals
-
The indicator light blinks when you use either
turn signal.
Whenever you use the left B or the right fl
turn s ignal, the indicato r light blinks . When
you use the emergency f lasher, both indicator
lights flash.
If one of the turn signal light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal.

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.

A WARNING
- Never p lace the selector lever in the R or
P posit ion while the veh icle is moving -
risk of an accident!
- With the engine running, it is necessary
to hold the vehicle with the foot brake in all se lector lever positions (except P and
N), because even at idle speed the trans­
fe r of power is never completely inter­
rupted -the vehicle "creeps". If the vehi­
cle is stationary and the transm ission is
engaged, the engine should never be
speeded up unintentionally (e .g. manual­
ly from under the hood). Otherwise the
veh icle w ill immediately start to move -
sometimes even if the park ing brake is
firmly applied -risk of an accident!
- Before you or other persons open the
hood and work on a running engine, the
selecto r lever must be moved to P and
the park ing brake applied f irmly - risk of
an accident! Follow the warning sticke rs
c::> page 187, Engine compartment.
(D Tips
