Homelink ®
Universal remote control
Applies to vehicles: w ith Home link® unive rsa l remo te cont rol
General information
The HomeLink® feature can learn up to three radio
frequency codes for most current transmitters used for
operating garage doors, estate gates, home or outdoor
lighting systems, and other devices.
You must first program the Homelink® transmitter before you can
use the
system=> page 191, "Programming the Homelink® trans­
mitter".
In order to program the Homelink® transmitter for devices utilizing
rolling code , a second person on a ladder who can safely reach the
garage door opener motor is recommended. It is also necessary to
locate the
"learn" button 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 original 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 feature as
required by federal safety standards. This includes any garage
door opener model manufactured before April 1, 1982.
• A garage door opener which cannot detect an object, signaling
the door to stop and reverse does not meet current federal safety standards . Using a garage door opener without these features
increases risk of serious injury or death.
Controls and equip­ ment
& WARNING (continued)
• For safety reasons never release the parking brake or start the
engine 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
programmed. If the device is repeatedly activated, this can over­
strain motor and damage its electrical components -an over­
heated motor is a fire hazard!
• To avoid possible injuries or property damage, please always
make absolutely certain that no persons or objects are located in
the range of motion of any equipment being operated. •

vidual components . It regulates consumption, so that more elec­
t rical energy is not be ing used than is be ing genera ted and ensures
an optimal state of charge for the battery .
[ i ] Tip s
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 275, "Driver notification in the instrument cluster
display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
T he battery is severely taxed in short -distance driving, in city traffic
and during t he co ld time of year . Abundant e lectrica l energy is
required, but on ly a little is generated . It is also critical if the engine
is not running and e lectrical components are turned on. In this
instance energy is being consumed but none is being generated .
I t is in precisely these situations that you wi ll notice energy manage ­
ment active ly regulating the d istr ibut ion of energy.
Vehicl e stands for an extended period
If you do not drive your vehicle over a per iod of several days or
weeks, electrica l components are gradually cut back or switched off.
This reduces energy consu mpt ion and maintains starting capability
over a longer period .
Be aware t hat when you unlock you r ve hicle, some o f the conve ­
nience functions may not operate, such as the Advanced Key, the
remote contro l or t he power seat adjustment. T he convenience
functions will be available again when you turn on the ignition and start the engine .
Controls and equip­
ment Safety first Vehicle operation With th
e engin e turned off
If you listen to the radio, for examp le, with t he engine tu rned off or
use other MMI functions, the battery is being discharged.
I f starting capabi lity is jeopardized due to energy consumption, the
f o llow ing warn ing appears in t he MMI display:
Ple ase start engine , other wise sy stem will s witch off in 3
minute s.
The warning indicates that the system wi ll be turned off au tomat i­
ca lly after 3 minutes. If you wish to continue using the functions,
you have to start the engine .
With the engine running
Although e lectrica l energy is generated when the vehic le is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal co nsumed
and the battery's state of charge is not optimal.
To br ing the ene rgy balance bac k into equi librium , cons umers
which require especially large amounts of energy are temporar ily
cu t back or switched off . Heating systems in part icu lar require a
great deal of energy. If you notice, for example, that the heated
seats* o r the heated rear w indow are not heating, they have been
temporari ly cut back or switc hed off. These systems wil l be avai lable
again as soon as the energy balance has been restored.
You wil l also notice t hat engi ne idle speed has been increase d
s lightly . This is norma l and not a cause for concern . By increasing
engine idle speed the addi tiona l energy required is ge nerated a nd
the battery is charged. •

checked by a service facility. The e lectrolyte level should also be
checked each time the battery is charged =>
page 321.
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With ce rtain types of airbag deployment, the battery is discon­
nected from the vehicle electrical system for safety reasons=>
& in
"Repair, care and disposal of the airbags" on
page 232.
Di sconn ecting the b atte ry terminal s
Some veh ic le functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected again. To
prevent this, the battery should only be disconnected from the
veh icle electrical sys tem when absolu tely necessary for repairs.
Veh icl es not driv en for lo ng p eriods
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumpt ion and maintains starting capability
over a longer period
=> page 274 .
Be aware that when you unlock your vehicle, some of the conve ­
nience functions may not operate, such as the Advanced Key*, the
remote control or the power seat adjustment. The convenience
functions will be ava ilable again when you turn on the ignition and
start the engine.
W int er operati on
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc. , are
used more often .
Avoid unnecessary power consumption, particularly in city traffic or
when trave ling only short distances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
=> page 321. A well charged battery will n ot only prevent starting
problems when the weather is cold, but wi ll also last longer.
[ i ] Tips
If your vehic le is left standing for severa l weeks at extreme ly low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. Th is wil l prevent it from be ing damaged and
having to be replaced.•
Working on the battery
Be espe cially careful when w orking on or near the battery.
