2. Press both of the outer buttons on the con­
trol unit
c:, page 30, fig. 25 unt il the yellow
LED @turns off and the green
LED (!) blinks.
This procedure clears the standard codes that
were set at the factory and does
not need to
be repeated again to program the other but­
tons .
3. Briefly press the button in the control panel
that you want to program.
4. Wait until the yellow LED@blinks. The pro­
gramming mode is active for five minutes.
S. Go in front of the vehicle with the original re­
mote control transmitter for the system that
you are programming to the control panel button.

radiator grille
6. Hold the remote control transmitter at the
vehicle radiator grille
¢fig . 26 .
7. Now press the remote control transmitter
until the turn signals on your vehicle blink.
This can take up to 30 seconds.
8 . If the emergency flashers blink three times,
the programming was successful. If the
emergency flashers only blink one time, the
five-minute time limit for programming has
expired or the programming was unsuccess­
ful. Repeat the programming procedure
starting from the third step or change the
distance to the radiator grille .
Opening and closing
9. If the garage door or other systems do not
open with the Home link buttons even if the
programming was successful, the system
may use a ro lling code instead of a fixed
code. You must also then perform
rolling
code programming
c:, page 32 .
The other two buttons in the control panel can be
programmed using the instructions given above.
Start with step 3.
Deleting button programming
The programmed buttons cannot be deleted indi­
vidually. They must be deleted all at once. Repro­
gram the buttons if necessary.
"' Switch the ignit ion on.

(D Tips
-The d istance needed between the remote
control transmitter and the Homelink mod­
ule in the radiator grille
c:, fig. 26 depends
on the system you are programming.
- Depending on the system model, you may need to release the button on the remote
cont rol transmitter while it is programming
and press it again. Hold every position you
try when programming for at least 15 sec­
onds before trying a new position. Keep an
eye on the vehicle turn signals while doing
this.

-Never turn off the engine before the vehicle
has come to a complete stop.
- The brake booster and power steering only
work when the engine is running. If the en­ gine is off, you have to use more force when
steering or braking. Because you cannot
steer and brake as you usually would, this
could lead to accidents and serious injuries.
@ Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately . This re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Move the selector lever into the P position .
... Press the I START ENGINE STOPI button.
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To switch the engine off, press
the
I START ENGINE STOPI button twice in a row
br iefly or press and hold for longer than two sec­
onds.
A WARNING
- Never turn off the engine before the vehicle has come to a complete stop.
Driving
-Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and braking capa­
bility is not available, the risk of accidents or
. . . . mJunes increases.
-For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes
-even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine is al­
ready warm and the engine compartment is
also heated by the sun's rays.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the
engine is
switched off and there is a risk of damaging
the engine . For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­ matically or it may continue to run (even if
the ignition is switched off) for the following
reasons :
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.

A WARNING
--
- Ser ious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when work ing
on the vehicle . Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never risk pe rsonal inj ury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fu lly famil iar with these
or other proced ures with respect to the ve­
h icle, or are uncerta in how to pro ceed.
- Do not do any work without the proper tools
and eq uipment. Have the necessary wo rk
done by your authorized Audi dealer or an­
other proper ly equipped and qualified work­
shop.
- The engine compartment of any motor vehi ­
cle is a potentially hazardous area . Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly
-even when the en­
g ine is off . The radiator fan switches on au­
tomatically when the coolant reaches a cer­
tain tempe rature and will cont inue to run
until the coolant temperature d rops.
- Always sw itch off the ignition before anyone
gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work underneath
the vehicle. The jack suppl ied with the veh i­
cle is no t adequate for this pu rpose and
could collapse caus ing serious personal in­
jury.
- I f you must wor k unde rneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
