(D Note
The instrument clu ste r and center c onsole i lluminati on (gauge s and
n eedles) comes on w hen you sw itch on the ignit ion and the vehicle
he adl ights are off . Be awa re of the following difference betw een
models built to US or Canad ian specificat io ns:
• USA models : illumination of the instrument cluster (gauges and
needles), dash and center con sole around the gear shift 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 driver , to
sw itch on the headlights befo re it gets too dark .
• Canada models: instrument panel illumination will stay bright
regardless of the intensit y of ambient light . Always be aware of
changes in outside light conditions while you are driving . Respond
in time to fading dayl ight by turning the light swit ch to position
jD
(or" AUTO" if you r car i s equi ppe d with this feature) to turn on your
headlights . •
Tachometer (engine rev counter)
T h e ta chom eter ind icates the e ngine RPM (revo luti ons pe r
minut es).
The tachom eter 0 => fig . 2 is the left on e of the two large clock -type
dis plays .
The engine turns at a speed 1 000
times the single di git in the
display, e.g . if the needle p oints at the "2", the eng ine t urns at
2 000 RP M.

Driver information display
Defective light bulb warning U
The defective light bulb warning tells you when a vehicle
light bulb has become defective.
If a defective bulb has been detected by the system or a light bulb
burns out, the symbol with a message appears in the display to
tell you which bulb is burnt out and where it is located. For example:
Rear left turn signal
After 5 seconds, the message disappears . If you want to recall the
message into the display, press the CHECK button=>
page 8, fig. 2
©-
There are three reasons why the defective bulb message would
appear in the display:
• The light bulb has burnt out=>
page 283.
• The fuse is "blown" => page 278, "Replacing a fuse".
• The wire connection to the light bulb is defective .
Have the bulb replaced or the connection repaired by your autho ­
rized Audi Service department.
& WARNING
• Light bulbs are pressurized and could explode while they are
being changed causing serious personal injury.
• Work with due care when handling the high-voltage section of
gas discharge (xenon) lamps. Failing to do so could result in death
or serious injury! •
Brake light defective " U'lf" (USA
models) / (Canada models)
In case of a malfunction or component failure, the symbol
(USA models)/ (Canada models) can appear . The following elec- trical components should be checked, repaired or replaced, as
necessary:
• Brake light bulbs
• All wiring connections
• Brake light switch
Contact your authorized Audi dealer for assistance if necessary.
[ i] Tips
The brake light switch is only inspected as part of the functional
check after the engine is started .•
A pplies to vehi cles : w it h a uto mati c he adl ights
Light /rain sensor defective _,
The indicator light indicates a defect in the automatic
headlights/automatic wiper system.
If the symbol illuminates, the light sensor has failed. For safety
reasons, the low beams are turned on permanently with the switch
in
AUTO. 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
windshield wiper lever functions are still available. Have the
light/rain sensor checked as soon as possible at an authorized Audi
dealer. •

Adaptive Light defective ~{)
C: Adaptive light defective
When this symbol J illuminates, it means that Adaptive Light is
defective. Go to a qualified workshop to have the headlights or the
control unit for the Adaptive Light repaired. •

Clear vision
The daytime running lights function cannot be turned off .
Automatic headlight control *
In the switch position AUTO the automatic he adlight contro l is
turned on . The low beams are turned o n automatically through a
light sensor as soon as ambient brightness (e .g. when driving into a
t unnel) falls below a value preset at the factory. When ambien t
brightness increases again, the low beams are turned off again
aut omatically ==>&, .
In the
AUTO position the low beams are switched off automatically
when the ignition is turned off.
Light S ensor M alfun ction *
In the even t of a light sensor malfunct ion, the driver is notified in the
instrument cluster display :
Automatic headlights /automati c w ipers defe ctive
For safety reasons the low beams are turned o n permanently w ith
the switch in AUTO *. However , you can continue to turn the lights
on and off us ing the l ight switch . Have the lig ht sens or checked as
soon as possib le at a dealership .
Coming home /leaving home function *
The function is switched on when the switch is in the AUTO* posi ­
tion and the f unction is shown as ac tive in t he d river info rmat ion
system .
The
c oming home function illuminates the area around the vehicle
when the ignition is switched off a nd the driver's door is opened.
The length of time the lights remain on can be set in the menu
display
(Illumination > Exterior lights > coming home ).
The leaving home function illuminates the area around the vehicle
whe n unlocking it .
& WARNING
• Nev er use daytime run ning light s to see whe re you are going .
They are not bright enough and will not let you see far enough
ahead for safety , espe cially at du sk or when it i s da rk . Al way s
s w itch on the low beam s at du sk or when it i s dark .
• Automatic headlight s are only intended to assist the driver .
They do not relieve the driver of hi s responsibility to check the
head light s and to turn them on manually according to the cu rrent
light and visibility conditions . For example , fog and rain cannot be
detected b y the l ight sen sor s. S o alwa ys switch on th e headl ight s
under these weather conditions and when driving in the dark
io.
• Cra she s c an happen when you cannot see the road ahead and
when you cannot be seen by other motor ists.
- Alway s turn on the hea dlight s so that you can see ahead a nd
so that other s can see your car from the ba ck.
[ i ] Tips
• With the swi tch in AUTO front fog ligh ts cannot be turned on in
addition.
• The light sensor for head light contr ol is located in the rear view
mirror mount. Do not apply any stickers to the windshie ld in this
area to p revent malfunctions or failures.
• Some exterior lighting functions can be adjusted in the driver
informa tion system
==> page 23.
• I f you remove the ignition from the ignition lock while the head ­
l ights are still on, a bu zzer w ill sound as long as the driver's door is
open to remind you to turn off the lights.
• Always observe t he specific local regulations for your area as to
when to use your lights.
• With automatic headl ights, the high -beam function is also avai l­
able, but with one restriction : If you have not switched the high
bea ms back to low beams duri ng automatic headlight operation (for
example , after driving through a tunne l), on ly the low beams come .,,_

on the next time automatic headlights are switched on. To use the
high beams, you first have to pull the high beam lever back and then
push the lever forward again.
• In cool or damp weather, the inside of the headlights, turn
signals and tail lights can fog over due to the temperature differ­
ence between the inside and outside. They will clear shortly after
switching them on. This does not affect the service life of the
lighting.
• 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. •
Applies to vehicles: with Adap tive Light
Adaptive light
When driving around bends, the relevant area of the road
is better illuminated.
Fig. 48 Adaptive light
when driving
The benefit of adaptive light is that the curve and the edge of the
road are better illuminated::::} fig . 48 . The adaptive light is controlled
automatically, depending on vehicle speed and steering wheel
angle.
Con tro ls and eq uip­
ment
Clear vision
When driving around bends, the headlights are controlled
according to steering wheel angle. So that there is no black area
ahead of the vehicle, the two main beams pivot at different angles .
[ i] Tips
The system works above a speed of about 6 mph (10 km/hl. •
