Power Contro l) illuminates when you turn on
the ignit ion as a f unct ion check.
(D Tips
If this war ning/ indica to r light illum inates
while yo u are d riving, then there is a mal­
funct ion in the engine electronics. Have
the malfunct ion corrected as soon as pos­
sib le by your authorized A udi dealer or
qualified workshop.
W Glow plug system
App lies to vehicles: wit h diese l eng ine
The control light illuminates when the glow
plug system is active.
If the mlJ indicator light illum inates, the glow

16 Instruments and warning/indicator lights
;;./~ Electronic Stability Control (ESC)
This warning/indicator light monitors the
Electronic Stability Control .
If the D] indicator lamp blinks while driving,
the ESC or ASR (Anti-Slip Regulation) is active­
ly regulating.
If the G] indicator lamp illuminates, the sys­
tem has switched the ESC off. In this case, you
can switch the ignition off and then on to
switch the ESC on again . The system is func­
tioning completely when the indicator lamp
switches off.
If the
I indicator lamp illuminates, the ESC
was switched off with the
I ~ OF F! button.
Stability program and ABS fault! See own­
er's manual
If the J;.j indicator lamp and the llJ ABS indi­
cator lamp illuminate and the driver message
appears, the ABS or electronic differential lock
is malfunctioning. This also interrupts the
ESC. The brakes still function with their nor­
mal power, but ABS is not active .
Drive to your authorized Audi dealer immedi­
ately to have the malfunction corrected.
For more information about the ESC

ii !.!r Safety systems
The I (USA models)/ . (Canada mode ls) in­
dicator light monitors the safety systems e.g.
a ir bags, pretensioners and illuminates for a
few seconds each time you switch the ignition
on .
If the
I (USA models)/ . (Canada models)
indicator light does not go out, or if it illumi­
nates while you are driv ing, or if it starts to
b link , then there is a malfunction somewhere
in the system. If the light does not illuminate
when you switch the ignition on, this also
means there is a malfunction.
A WARNING
If you have a ma lfunction in the safety sys­
tems, contact your authorized Audi dealer
imme diately. Otherwise the safety sys­
tems may not work properly in an acc i­
dent.
¢ Q Turn signals
The indicator light blinks when you use either
turn signal .
Whenever you use the left B or the right B
turn signal, the indicator light blinks. When
you use the emergency flashers, both indica­
tor lights flash.
If one of the turn signal light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal.
This does not apply, however, in towing mode.
The indicator light does not flash if a turn sig­
nal is out on the trailer or the towing vehicle .

ACC not available
The text message ACC not available appears,
for example, if the temperature of the brakes
i s excessive. Adaptive cruise control is tempo­
rarily not available. A warning tone sounds as
a reminder .
ACC not available!
The text message ACC not available! appears

pears when the ACC System can no longer ac­
curately detect vehicles moving up ahead in
your lane of travel. Adaptive cr uise control is
turned off. A warning tone also sounds as a re­ minder.
To decide whether it is necessary to switch off
the ACC (ACC sensor blocked
!) or if it is only a
temporary condition (ACC Functionally limit­
ed), the system will a lso takes into cons idera­
tion the outside temperature and/or the wind­
shield wiper operation .
The ACC sensor is dirty or blocked (e.g. leaves,
snow).
The ACC sensor is loca ted behind the area to
the right of the front license plate . If the ACC
sensor is dirty or blocked, clean the area to re­
store system operat ion.
Stability program

pears when the ACC System does not detect
any moving vehicles up ahead in your lane of
trave l for a longer period of time . During t his
time, the distance to moving vehicles in your

t rees). As soon as a moving vehicle up ahead
is detected again, ACC becomes active again
and the message disappears.

Homelink ®
Universal remote
control
General information
Applies to vehicles: with Home link® universal remote
control
The Homelink ® feature can learn up to three
radio frequency codes for most current trans­
mitters used for operating garage doors, es­ tate gates, home or outdoor lighting sys­
tems, and other devices.
You must first program the Homelink ® trans­
mitter before you can use the system
~ page 157, Programming the Homelink ®
transmitter.
In order to program the Home link ® transmit­
ter for devices utilizing rolling code, a second
person on a ladder who can safe ly reach the
garage door opener motor is recommended. I t is also necessary to locate the "learn" but­
ton on your garage door opener motor . Refer
to the operating instructions for the opener,
as the location and color of this button may
vary by manufacturer.
You can still use the origina l remote control
for the device at any time .
.&_ WARNING
-
- Never use the Homelink ® transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federa l safety stand­
ards. Th is includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signa ling the door to stop
and reverse does not mee t current feder ­
al safety s tandards. Using a garage doo r
opener without these features increases
risk of serious inj ury or death.
- F or sa fety reasons never release the
parking brake or start the engine w hile
anyone is stand ing in front of the vehicle . -
A garage door or an estate gate may
sometimes be set in mot ion when the
Homelink ® remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its e lectr ical components -an
overheated moto r is a fire hazard!
- To avo id possible injuries or property
damage, please always make abso lutely
certain that no persons o r objects are lo­
cated in the range of motion o f any
equ ipment being ope rated .
