Instrument s and warning /indicator lights 11
,&_ WARNING
- Always observe the warning in
¢ page 213, Engine compartment, be­
fore opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the radiator . At h igh outside
temperatures or high engine load, the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engin e RPM
(r evolutions per minutes).
If engine RPM d rops be low 1,500 , you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod . Before reaching this a rea, move these­
lector lever to position D/S or ease your foot
off the accelerator pedal.
(D Note
The tachometer needle@¢ page 10,
fig . 3
shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend­
ing on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

press on the key for an extended period.
A WARNING ~
- Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the power steering is not guaranteed. You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could lead to crashes and serious injuries.
- For safety reasons, you should always
park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
- The radiator fan can continue to run for
up to 10 minutes
even after you have
turned off the engine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.
- Always take the key with you whenever
you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated. This can lead to seri­
ous injury.
- Never leave children or persons requiring
assistance unattended in the vehicle . The
doors can be locked using the remote
transmitter, preventing people from es­ caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, people inside the

Homelink®
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control con
be programmed with the remote control for
devices that ore already present.
With Home Link, you can control devices such
as the garage door, secu rity systems, ho use
lights , etc. comfortably from the inside of you
vehicle .
H omelink makes it poss ible for you to rep lace
three different remote controls from dev ices
i n your home with one universal remo te. Th is
featu re works for most garage door and exte­
rior door motor signals. Programming the in­
d ividual remote control for your remote con ­
trol takes p lace near the center of the radiator
grille. There is a control module attached at
this location .
A one-t ime programm ing of the sensor must
be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-t ime pro­
gramming, check whether the system uses a rolling code ¢
page 126 for vehicles without
the MMI*.
,& WARNING
-
-Never use the Homelink ® transmi tter
with any garage door opener that does have not the sa fety stop and reverse fea ­
ture as requ ired by federa l safety stand­
ards. Th is includes any garage door open­
er mode l manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Us ing
a garage door
opener without these features increases
risk of serious injury or death.
Homelink ® 123
-For safety reasons never re lease the
parking brake or start the eng ine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the Homelink ® remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its e lectrical components -an
overheated mo to r i s
a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certain that no person s or objects are lo­
cated in the range of motion of any
equ ipment being operated .

You can program the fixed code and rolling
code systems using the described procedure.
Programming the button
• Turn the ignition on .
• There are two ways to program the button:
Press the button¢ page
123, fig. 136 that
you would like to program. Use the instruc­

• Select the button that you would like to
program.
• Follow the instructions in the
MMI*.
• If the garage door opening must also be
synchronized with the Homelink module,
refer to the owner's manual for the garage
door opener. Remote
control units for garage door openers
in Canada are set to stop transmitting radio
frequency signals after two seconds. This time
may not be sufficient for the Home link sys­
tem to learn the radio frequency signal. Per·
form all other steps as described above .
Erasing/Clearing the programmed button
settings
• To erase all of the programmed buttons at
the same time, select:
I CAR I function button
> Car Systems" control button > Vehicle set­
tings
> Garage door opener> Clear pro­
gram settings > Yes.
The programmed but­
tons can not be erased individually . Repro­

-The required distance between the hand
transmitter and the HomeLink module in
the radiator grille
c:> fig. 138 depends on
the system that you are programming.
- Depend ing on the model of the garage
door opener, you may need to release the
button on the remote and press it again
when programming . When program­
ming a new dev ice, keep the button
pressed for at least 15 seconds befo re
trying again with the transmitter in a dif­

gency flasher during that time .
Programming the rolling code
Applies to vehicles: with Home link
Additionally, a rolling code programming for
the HomeLink universal remote control is re­
quired for some systems .
Identifying the rolling code
.. Press the prev ious ly programmed Homelink
button aga in and hold i t down .
.. Look at the LED@ c:>
page 123, fig. 136 . If
the LED b links quickly , the features, s uch as
the garage door opener, are equipped with
the rolling code .
.. Program the roll ing code as fo llows:
Act ivating the g arage door opener motor
unit
.. Locate the sett ing button on the garage
door opener motor unit . The exact location
and co lor of the button may vary depending
on the garage door opener manufacturer .
.. Press the sett ing button on the garage door
opener motor unit (usually th is w ill act ivate
a "sett ing light d isp lay" on the motor unit).
Now you w ill have about
30 second s time to
perform the HomeL ink button programming
on the cont ro ls.
Programming on the controls
.. Press the Home L ink button that was already
programmed and hold for two seconds . ..
To end ro lling code programm ing, press and
hold the Home link button for two seconds
aga in .
.. The Homelink button may need to be press­
ed a third t ime to end the adjus tment proce­
dure for some garage door openers .
After the controls have been programmed, the garage door opener should recogni ze the
Homelink signal and operate when the Home­
Li nk button is pressed . Now you may program
the other buttons as needed .
(D Tips
-Programming the rolling code can be
performed quicker and more easily with
the help of a second person .
- If d iff iculties should arise when pro­
gramming the rolling code, consult the
operating instructions for the garage
door opener or o ther dev ices for po ssible
solutions.
