HomeLinkUniversal transmitterApplies to vehicles: with HomeLinkDescription
The HomeLink universal transmitter can be programmed
to replace the hand-held cont rols of devices already in
use.HomeLink allows you to conveniently activate garage doors, estate
gates, security systems, home or office lighting and other electric
devices by means of control buttons inside your car.
HomeLink can replace up to three hand-held transmitters operating
existing devices on your property with a single universal trans-
mitter. This will be possible for most transmitters which control the
drive units for a garage door or external gates, etc. You can
programme the individual hand-held transmitters for your remote
control at or near the centre of the radiator grille. This is where the
control unit is located.
To be able to control systems with HomeLink, you need to perform
initial programming on the HomeLink transmitter first. If systems
fail to respond after the initial programming, check whether these
systems work with a "rolling code" (variable security code)
⇒ page 180 .
WARNING
When you are programming the Ho meLink universal transmitter,
make sure that no persons or objects are close to the devices
receiving the transmitter signals. If a gate or door is inadvertently
set into motion during progra mming, persons might be injured or
other damage caused by moving parts.

At the operating unit
1. Switch on the ignition (do not start the engine).
2. Press and hold down the two outer HomeLink buttons ⇒page 179, fig. 197 until the indicator diode
⇒ page 179, fig. 197 begins to flash after about
20 seconds. This procedure will delete the standard
factory settings and does not need to be repeated when
programming the other buttons.
3. Press the particular HomeLink button which you would like to program.
4. Wait until the diode begins to flash. The HomeLink module now remains in trai ning mode for 5 minutes.
5. Now step in front of your vehicle with the original hand-
held transmitter for the garage door opener or any other
device you wish to assign to the HomeLink control
button.
At the radiator grille
6. Hold the original hand-held transmitter at or near the
centre of your car's radiator grille ⇒ page 179, fig. 198.
7. Press the activator button on the original hand-held
transmitter .
8. As you do so, watch the tu rn signals on your vehicle.
HomeLink confirms successful programming by flashing
all four turn signals three times.
9. If the turn signals fail to flash three times, repeat the procedure with the transmitter held at a different
distance from the radiator grille.
The proper distance between the hand-held transmitter and the
HomeLink module at the radiator grille depends on the system you
want to train. It may require several attempts.
The turn signals will flash once if the time limit for the programming
mode has been exceeded. In this case the programming procedure
needs to be performed again. Repe at the sequence at the operating
unit starting with step 3.
The programming instructions above also apply to the other control
buttons. Start with step 3 if you wish to proceed and program the
other two buttons.
If the garage door or other devices st ill fail to be activated with the
HomeLink control buttons after programming is completed, it is
possible that these systems might be working with a rolling code
instead of the normal fixed security code. If this is the case, a rolling
code programming is required in addition to the steps described
above. ⇒page 180Applies to vehicles: with HomeLinkRolling code programming
Some devices require rolling code programming of the
HomeLink universal transmitter.Identifying a rolling code
– Press the already programmed HomeLink button again
and hold it down.
–Watch HomeLink diode ⇒ page 179, fig. 197. If the
diode starts flashing rapidly and turns into a constant
light after about 2 seconds, this indicates that the device
you wish to operate (e.g. a garage door opener) is
equipped with a rolling code.
– Program the rolling code as follows:

Before every trip
The driver is responsible for the safety of the passengers
and the safe operation of the vehicle at all times.For your own safety and the safety of your passengers,
always note the following points before every trip:
– Make sure that all lights and turn signals are working
properly.
– Check the tyre pressures.
– Make sure that all windows are clean and give good visi- bility to the outside.
– Secure all luggage and other items carefully ⇒page 79 .
– Make sure that no objects can interfere with the pedals.
– Adjust the front seat, head restraint and mirrors correctly.
– Make sure that the head restraints for all passengers are adjusted to the correct position.
– Make sure that children are protected with suitable safety seats and properly worn seat belts ⇒ page 210.
– Sit in the correct position in your seat and make sure that
your passengers do the same. ⇒page 73 .
– Fasten your seat belt correctly. Make sure that your passengers do the same ⇒page 194.
What affects driving safety?
Safety on the road is directly related to how you drive, and
can also be affected by the passengers in the vehicle.The driver is responsible for the safety of the vehicle and all
its occupants. If your ability to drive is impaired in any way,
you endanger yourself and other road users ⇒. There-
fore:
– Do not let yourself be distracted by passengers or by using a mobile phone, etc.
– Never drive when your driving ability is impaired (by medication, alcohol, drugs, etc.).
– Obey all traffic regulations and speed limits and always maintain a safe distance to the vehicle in front.
– Always adjust your speed to suit the road, traffic and weather conditions.
– Take frequent breaks on long trips. Do not drive for more than two hours without a stop.
– If possible, avoid driving when you are tired or stressed.
WARNING
•
Distractions while driving or any kind of impairment to your
driving ability increase the risk of accident and injury.
•
Do not store loose objects on the dashboard. These objects
could fly around the interior when the vehicle is moving (under
acceleration or whilst cornering) and distract the driver – this
could lead to an accident.

Safe driving
188Correct sitting positionsCorrect sitting position for driver
The correct driving position is important for safe and
fatigue-free driving.For your own safety, and to reduce the risk of injury in the
event of an accident, we re commend the following driving
position.
– Adjust the steering wheel so there is a distance of at least 25 cm between the steering wheel and your breastbone
⇒fig. 199. – Move the driver's seat forwards or backwards so that you
can press the accelerator, brake and clutch pedals all the
way to the floor with your knees slightly bent ⇒.
– Make sure that you can comfortably reach the top of the steering wheel.
– Adjust the head restraint so that the top of the head restraint is level with the top of your head ⇒fig. 200.
– Adjust the backrest to an upright position so that your back remains in contact with the upholstery.
– Fasten your seat belt correctly ⇒page 194 .
– Keep both feet in the footwe ll so that you are in full
control of the vehicle at all times.
For detailed information on how to adjust the driver's seat, see
⇒ page 73, “Seats and storage”.
WARNING
•
A driver who is not sitting in the correct position or who is not
wearing a seat belt can be fatally injured if the airbag is triggered.
•
Adjust the driver's seat so there is a distance of at least 25 cm
between your breastbone and th e centre of the steering wheel
⇒ fig. 199.
•
While driving, always hold the steering wheel with both hands
on the outside of the rim at about the 9 o'clock and 3 o'clock posi-
tion. This reduces the risk of injury if the driver's airbag inflates.
•
Never hold the steering wheel at the 12 o'clock position, or
with your hands inside the rim or on the steering wheel hub. This
could result in serious injuries to the arms, hands and head if the
driver's airbag inflates.
•

inside. In this case the child wo
uld be unable to get out of the
vehicle without help. This could have fatal consequences.
•
Never allow children to play in or around the vehicle. Always
close and lock the boot lid and all the doors when you leave the
vehicle.
•
Never let passengers ride in the luggage compartment. All
occupants must be properly restrained by the seat belts at all
times ⇒page 194 .Note
•
Air circulation in the vehicle helps reduce fogging of the
windows. Used air escapes through ventilation slots in the rear of
the vehicle. Make sure that these ventilation slots are not
obstructed.
•
Suitable belts for securing loads to the fastening rings* are
commercially available.
Applies to vehicles: with fastening ringsFastening rings
Unsecured loads are a hazard to all vehicle occupants.There are fastening rings in the luggage compartment
which can be used to secure luggage and other objects
⇒ page 79 .
– Use the fastening rings to secure items safely in the luggage compartment ⇒ in “Loading the luggage
compartment” on page 79.During a collision or an accident, even small and light objects can
possess so much energy that they can cause very severe injuries.
The amount of this “kinetic energy” depends on the speed of the vehicle and the weight of the object. The most significant factor,
however, is the speed of the vehicle.
An example: An object weighing 4.5 kg is lying unsecured in the
vehicle. During a frontal collision at a speed of 50 km/h, this object
generates a force corresponding to 20 times its weight. That means
that the effective weight of the object increases to about 90 kg. You
can imagine the severity of the injuries which might be sustained if
this “projectile” strikes an occupant as it flies through the
passenger compartment.
WARNING
If items of luggage or other obje
cts are secured to the fastening
rings with inappropriate or da maged retaining cords, injuries
could result in the event of sudden braking or a collision.•
To prevent pieces of luggage or other objects from flying
forward, always use appropriate retaining cords which are prop-
erly secured to the fastening rings.
•
Never secure a child seat on the fastening rings.

Airbag system
206Important safety notes on the side airbag system
There are a number of safety points concerning the airbag
system which you should remember. This will help to
reduce the risk of injury in an accident.
WARNING
•
If you do not wear a seat belt, if you lean forward, or are not
seated correctly while th e vehicle is in motion, you are at greater
risk of injury should the side airbags on the front seats or the outer
rear seats* be triggered in an accident. This applies particularly to
children if they are not properly protected by a child restraint
system ⇒page 212, “Important notes on side airbags and child
safety”.
•
If children are not seated correctly, they are at greater risk of
injury in an accident. This is particularly the case if the child is
travelling on the front passenger's seat and the airbag system is
triggered. This could result in serious or potentially fatal injury
⇒ page 210, “Child safety”.
•
It is also important not to attach any accessories (such as cup
holders) to the doors. This would impair the protection offered by
the side airbags (front and rear*).
•
The sensors for the airbags are lo cated in the front doors. You
must therefore not make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers ), as this could impair the func-
tion of the side airbags. Any dama ge to the front doors could lead
to faults in the system. Repairs or any other work on the front
doors must therefore always be carried out by a qualified work-
shop.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy or sharp-edged objects in the
pockets.
•
Do not apply excessive force to the sides of the backrests (such
as hard knocks or kicks), as this could damage parts of the system.
The side airbags could then fail to operate when required.
•
If you intend to fit protective covers over the seats, these must
be of the specific type approved for use on Audi seats with side
airbags. Conventional seat covers would obstruct the side airbag
when it inflates out of the ba ckrest, and seriously reduce the
airbag's ef fectiveness.
•
Any damage to the original seat upholstery or around the
seams of the side airbag units must be repaired immediately by a
qualified workshop.
•
Any work involving the side airbag system or removal and
installation of the airbag components for other repairs (such as
repairs to the seats) must always be performed by a qualified
workshop. Otherwise the airbag system may fail to work
properly.WARNING (continued)

208second). The airbag releases a fine dust when it inflates. This is quite
normal and does not mean there is a fire in the vehicle.Important safety notes on the head-protection airbags
There are a number of safety points concerning the airbag
system which you should remember. This will help to
reduce the risk of injury in an accident.
WARNING
•
It is important to ensure that the area around the openings for
the head-protection airbags remains unobstructed at all times, so
that the airbags can in flate properly if needed.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy or sharp-edged objects in the
pockets. When using the coat hooks, do not hang the clothes on
coat hangers.
•
The space between the passenge rs and the head-protection
airbags must never be occupied by children, other passengers or
pets. Passengers should never lean out or put a hand or arm out of
the window while the vehicle is in motion.
•
Do not move the sun visors out to cover the side windows if
there is anything attached to th em (such as pens or a remote
control for the garage door). These objects could cause injury if the
head-protection airbag is triggered.
•
The sensors for the airbags are lo cated in the front doors. You
must therefore not make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers ), as this could impair the func-
tion of the side airbags. Any dama ge to the front doors could lead
to faults in the system. Repairs or any other work on the front
doors must therefore always be carried out by a qualified work-
shop.
•
Where sun blinds are fitted on th e rear doors, these must not
obstruct or impair th e airbags in any way.
•
If unsuitable accessories are installed near the head-protection
airbag, the protection afforded by the airbag can be seriously
impaired if the system is trigge red. When the head-protection
airbag opens, parts of these acce ssories could be thrown into the
vehicle and injure passengers ⇒page 277 .
•
Any work involving the head-protection airbags, or removal
and installation of the airbag components for other repairs (such
as repairs to the roof liner), mu st always be performed by a quali-
fied workshop. Otherwise the airbag system may fail to work
properly.
Applies to vehicles: with key-operated switch for front passenger's airbagDeactivating the front passenger's airbag via the key-operated switchIf an airbag has been deactivated, it should be reactivated
as soon as possible so that it can continue to give the
required protection.

safety seat is in use
If you have no alternative but to i nstall a rearward-facing child safety
seat on the front passenger's seat you must deactivate the front
passenger's airbag beforehand.
We recommend, however, that child seats should be only fitted on
the rear seat so that the front passenger's airbag can remain func-
tional and provide protection in an accident ⇒page 210 .
Monitoring of airbag system
The airbag warning lamp will light up for a few seconds every time
the ignition is switched on.
If the front passenger's airbag ha s been deactivated via the key-
operated switch, the indicator lamp “PASSENGER AIRBAG OFF” will
light up constantly as a reminder ⇒page 209, fig. 223. Please refer
also to the description of the
 warning lamp in the instrument
cluster ⇒page 17 . When the front passenger's airbag is deactivated using the key-
operated switch, the seat belt warning lamp for the front passenger

⇒ page 18 is also switched off.
WARNING
•
If you have no alternative but to install a rearward-facing child
seat on the front passenger's se at, the front passenger's airbag
must be deactivated beforehand. Po tentially fatal injuries to the
child can result if the front passenger's airbag is not deactivated!
⇒ page 211, “Using a child safety seat on the front passenger's
seat”
•
If you have deactivated the fron t passenger's airbag, reactivate
it as soon as the chil d seat is no longer needed so that the airbag
can continue to give the required protection.
