WARNING
•
The accelerator pedal must on no account be pressed inadvert-
ently when a gear is engaged with the vehicle stationary. If this
were to happen, the vehicle would start to move immediately, and
even a firmly applied handbrake might not restrain it (accident
risk).
•
To avoid accidents, apply the handbrake firmly and select
neutral gear (N) before opening the engine lid and working on the
vehicle with the engine running. Please observe the important
safety warnings ⇒page 155, “Working on components in the
engine compartment”.Note
If you accidentally shift to N when driving, you can engage a gear in

HomeLink 96
At the operating unit
1. Switch on the ignition (do not start the engine).
2. Press and hold down the two outer buttons of the
HomeLink® operating unit ⇒page 95, fig. 80 until the
indicator diode ⇒page 95, fig. 80 begins to flash after
about 20 seconds. This means that all previously stored
data has been deleted.
3. Press the particular HomeLink button which you would
like to program.
4. Wait until the diode ⇒page 95, fig. 80 begins to flash.
The HomeLink module now remains in training 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
⇒fig. 81.
At the front bumper
6. Hold the original hand-held transmitter for the device
you wish to program close to the front bumper, directly
above the radiator grille ⇒fig. 81.7. Press the activator button on the original hand-held
transmitter.
8. As you do so, watch the turn 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 bumper.
The proper distance between the hand-held transmitter and the
HomeLink module inside the front bumper 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. Repeat the sequence on the operating
unit starting with step 3.
The programming instructions above also apply to the other control
buttons. Start with step 3 on the operating unit if you wish to
proceed and program the other two buttons.
If the garage door or other devices still 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 97.

Airbag systemDescription of airbag systemGeneral notes on airbag system
The airbag is an integral part of the car's passive safety
system.In conjunction with the three-point seat belts, the airbag system
gives the front occupants additional protection for the head and
chest in the event of a severe frontal collision.
In a side collision the side airbags reduce the risk of injury to the
areas of the body facing the impact ⇒.
In addition to their normal function of protecting the occupants in a
collision, the seat belts also hold them in a position where the
airbags can inflate properly and provide maximum protection.
The airbag system will only work with the ignition on. The airbag
system is monitored electronically; the airbag warning lamp indi-
cates whether the system is functioning properly.
The main parts of the airbag system are:•
the electronic monitoring system (control unit and sensors),
•
the two front airbags,
•
The two side airbags,
•
The airbag warning lamp in the instrument cluster.
There is a fault in the airbag system if the warning
lamp
•
does not come on when the ignition is switched on,
•
does not go out about 3 seconds after the ignition is switched
on,
•
goes out and then comes on again after the ignition is switched
on,
•
comes on or flickers while the car is moving.
WARNING
•
The airbags are not a substitute for the seat belts; they are an
integral part of the car's overall passive safety system. The airbags
can only offer effective protection if the occupants are wearing
their seat belts. For this reason it is very important to wear the
seat belts at all times ⇒page 109, “Why is it so important to use
seat belts?”.
•
The seat belts and airbags can only provide maximum protec-
tion if the occupants are seated correctly ⇒page 67, “Seats and
storage”.
•
If you do not wear a seat belt, if you lean forward, or are not
seated correctly while the vehicle is in motion, you are at greater
risk of injury should the airbag system be triggered in an accident.
•
Components of the airbag system are located in various parts
of the vehicle. If repairs to other vehicle components make it
necessary to perform work on the airbag system or to remove or
install parts of the airbag system, this may cause damage to the
airbag system. As a result, the airbags may not inflate correctly or
may not be triggered at all in an accident situation.
•
If a fault should occur in the airbag system, have the system
checked immediately by a qualified workshop. Otherwise the
system may fail to trigger in an accident.
•
Do not attempt to modify components of the airbag system in
any way.
•
Never make any alterations to the front bumper or the body.
•
The airbag system can only be activated once; if the airbag has
been triggered, the system must be replaced. Should the airbag
system or airbag modules have to be replaced, the qualified work-
shop carrying out the replacement will document all details in the
appropriate section of the Service Schedule.

Airbag system 120•
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) should always be performed by a qualified
workshop. Otherwise the airbag system may fail to work
properly.
Deactivating the airbagsDeactivating airbags
If airbags have been deactivated, they should be reacti-
vated as soon as possible so that they can continue to
give the required protection.There are two ways of deactivating the airbags: you can deactivate
the front passenger's airbag yourself by means of the key-operated
switch ⇒page 120. The other airbags can be deactivated by your
Audi R8 dealer.
Deactivating front passenger's airbag when a child
safety seat is in use
If you have no alternative but to install a rearward-facing child safety
seat on the front passenger's seat you must deactivate the front
passenger's airbag beforehand.
Monitoring of airbag system
The airbag warning lamp will light up for a few seconds every time
the ignition is switched on.
WARNING
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated – this can result in potentially fatal injuries to the child
⇒page 123.
•
Make sure that the front passenger's airbag is reactivated by
means of the key-operated switch as soon as the child seat is no
longer needed on the front passenger's seat.

WARNING
•
Do not wash the vehicle with the ignition switched on – risk of
accident.
•
Do not clean the underside of the car or inside the wheel arches
without protecting your hands and arms. You may cut yourself on
sharp metal parts.
•
Take care when washing the car during the winter: moisture
and ice on the brakes may affect braking efficiency – this could
cause an accident.Caution
•
Compare the track width of your vehicle with the distance
between the guide rails for the wheels in the car wash. Otherwise
there may be a risk of damaging the wheel rims and tyres.
•
Compare the ground clearance of your vehicle with the height of
the guide rails for the wheels in the car wash to prevent any damage
to the underside.
•
Compare the width of your vehicle with the available width when
entering and driving through the car wash.
•
Retract the exterior mirrors to avoid damage. Electrically retract-
able exterior mirrors must NOT be folded in or out by hand. Always
use the electrical power control.
•
Do not wash the vehicle in direct sunlight – otherwise the paint
can be damaged.
•
Do not use insect sponges, or abrasive household sponges, etc.
– they can damage the surfaces.
•
The headlights should only be washed with water – do not wipe
them with a dry cloth or sponge. It is best to use soapy water.
•
Never wash tyres with a jet that sprays the water out in a direct
stream. This could damage the tyres – even if the spray is kept at a
distance and only used for a very short time.
For the sake of the environment
The car should only be washed in special wash bays. This prevents
oily water from getting into the public drains. In some districts,
washing vehicles anywhere else may be prohibited.Waxing and polishingWaxi ng
Waxing protects the paintwork. It is time to apply a good coat of wax
when water no longer forms droplets and rolls off the clean paint-
work.
Even if a wax solution is used regularly in the car wash, it is advis-
able to protect the paint with a coat of wax at least twice a year.
In the summer, you will find it is much easier to remove dead insects
(which accumulate on the bumper and front lid) if the car has been
waxed recently.
Polishing
Polishing is only necessary if the paint has lost its shine, and the
gloss cannot be brought back by putting on wax.
The car must be waxed after polishing if the polish used does not
contain wax compounds to seal the paint.
Caution
Matt painted and plastic parts must not be treated with wax or
polish.Ornamental trim and mouldingsThe metal brightwork on the body is made of aluminium rather than
chrome (for environmental reasons).
