Technical data The front airbag for the driver is located in the padded hub of the
steering wheel ⇒page 116, fig. 95. The front airbag for the front
passenger is in the dashboard above the glove box ⇒fig. 96. The
locations of the airbags are marked with the word “AIRBAG”.
In conjunction with the three-point seat belts, the front airbags give
additional head and chest protection for the driver and front
passenger in the event of a severe frontal collision ⇒ in “Impor-
tant safety notes on the front airbag system” on page 117.
How the front airbags work
When fully inflated, the airbags reduce the risk of head or
chest injury.
The airbag system is designed so that the airbags for the driver and
front passenger are triggered in a severe frontal collision.
In certain types of accident the front airbags and the side airbags
may be triggered together.
When the system is triggered, the airbags fill with a propellant gas
and open out in front of the driver and front passenger ⇒fig. 97. In
order to provide the desired extra protection in an accident, the
airbags have to inflate extremely rapidly (within fractions of a
second). The fully deployed airbags cushion the forwards move-
ment of the front occupants and help to reduce the risk of injury to
the head and the upper part of the body.
Special openings in the airbag allow the gas to escape at a
controlled rate to restrain the forward movement of the occupant's
head and torso. Once the impact has been absorbed, the airbag
deflates sufficiently for the front occupants to see forward.Important safety notes on the front 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.

Intelligent technology 132Intelligent technologyElectronic stabilisation program (ESP)The Electronic Stabilisation Program increases the car's
stability.Description
The anti-lock brake system (ABS), the electronic differential lock
(EDL) and the traction control system (ASR) are all integrated into
the electronic stabilisation program (ESP). The ESP is designed to
enhance the control over the vehicle in critical handling situations,
such as when accelerating and cornering. It reduces the tendency to
skid at all speeds under all road conditions and improves the
stability and roadholding of the vehicle. ESP helps the car to start
moving, accelerate and climb a gradient in slippery conditions
where this may otherwise be difficult or even impossible. The ESP is
switched on automatically when the engine is started. It should
normally be left switched on at all times for optimum car stability.
Driving situations
If the car is oversteering (rear wheels losing grip first) the ESP
mainly brakes the outside front wheel; if the car is understeering
(front wheels losing grip first), the ESP brakes the inside rear wheel
and possibly also other wheels. This automatic brake application is
accompanied by characteristic noises.If, when braking, one of the wheels is turning too slowly in relation
to the road speed and is close to locking up, the system will reduce
the pressure in the brake line to this wheel. The driver is made aware
of this control process by a pulsating of the brake pedal and accom-
panying noise. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application
- do not “pump” the brake pedal. However, the ABS will not neces-
sarily guarantee shorter stopping distances in all conditions. For
instance, on loose gravel or fresh snow on top of an icy surface the
stopping distance with ABS may even be slightly longer.
Whenever it detects a significant difference in the speed of the driven
wheels of one axle (for example, if the road is slippery on one side)
the electronic differential lock (EDL) applies the brake to slow down
the spinning wheel so that more of the power is directed to the
other wheels. This function is active up to about 100 km/h. The brake
system will make noises while it is working.
If one wheel has less grip and starts spinning (for instance, if one of
the driven wheels is on ice), press the accelerator hard until the car
starts moving.
If the wheels start to spin, the traction control system (ASR) auto-
matically reduces the engine torque to match the amount of grip
available.
Activating the sport mode
If required (for instance if you want to use the launch control), you
can switch the traction control system (ASR) and electronic stabili-
sation program (ESP) to sport mode by pressing the button
once. The ESP warning lamp will light up and the message ASR off
will appear in the driver information system display. The amount of
wheel slip is regulated according to the road speed. You should only
use this feature if your driving ability and traffic conditions allow
you to do so safely.

Technical data Switching off the ESP and traction control system
(ASR)
To switch off the ASR and ESP in certain situations (e.g. when
driving with snow chains, in deep snow, or on a loose surface, or
when rocking the car backwards and forwards to free it from mud)
press the button for longer than 3 seconds. The ESP warning
lamp will light up and the message ESP switched off will appear in
the driver information system display. You should only use this
feature if your driving ability and traffic conditions allow you to do
so safely.
Switching on the ESP/traction control system (ASR)
To activate the ASR/ESP, press the button again.
Overheating of the brakes
To prevent the disc brake of a braked wheel from overheating, the
EDL cuts out automatically on the wheel in question if subjected to
excessive loads. The car remains operational and will behave in the
same way as a car without EDL.
The EDL will switch on again automatically when the brake has
cooled down.
WARNING
•
The grip provided by the ESP, ABS, EDL and ASR systems is still
subject to the physical limits of adhesion. Always bear this in
mind, especially on wet or slippery roads. If you notice the
systems cutting in, you should reduce your speed immediately to
suit the road and traffic conditions. Do not let the extra safety
features tempt you into taking any risks when driving – this can
cause accidents.
•
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow too close behind the vehicle in front of you. Please bear in
mind that even ESP, ABS, EDL and ASR cannot compensate for the
increased accident risk.
•
When accelerating on a uniformly slippery surface (for instance
all four wheels on ice or snow), press the accelerator gradually and
carefully. The driven wheels may otherwise start to spin (in spite
of the EDL), which would impair the car's stability and could lead
to an accident.
•
Please note that, when the traction control system (ASR) or
ASR/ESP is switched off, the driven wheels may start to spin,
causing the vehicle to lose grip, in particular on slippery or wet
roads - danger of skidding!Note
•
In the event of a malfunction in the rear spoiler system or in the
Audi magnetic ride, it may not be possible to switch off the traction
control system (ASR) or ASR/ESP, or the ASR/ESP may be reactivated
automatically from the deactivated status.
•
If a malfunction should occur in the EDL, this is indicated by a
warning lamp ⇒page 19.
•
Some racing circuits (e.g. with banked curves) can affect the
behaviour of the ESP.

Care of vehicle and cleaning 148In the case of normal surface dirt you can use a foam cleaner. Use a
sponge to spread the foam on the textile surface and to work it into
the material lightly. However, make sure that the textile material
does not become soaking wet. Then dab off the foam with a dry and
absorbent cloth (e.g. a micro-fibre cloth) and vacuum off any
residue once the surface is completely dry.
Removal of stains
To treat stains caused by spilled drinks (coffee, fruit juice or similar)
make up a solution with a mild detergent for sensitive fabrics and
apply it with a sponge. If the stains are difficult to remove, a
washing paste can be applied directly onto the stain and worked
into the fabric. The surface will then have to be wiped with clear
water to remove any residue left by the paste. To do so, use a damp
cloth or sponge and then dab the stain with an absorbent cloth.
Treat chocolate or make-up stains with a washing paste and then
rinse off with water (using a damp sponge).
A spirit-based cleaner can be used to remove grease, oil, lipstick or
ball point pen. Then dab the dissolved grease or colour particles off
with an absorbent cloth or similar. You may also have to treat the
stain once more using washing paste and water.
If the covers or textile trim panels are badly soiled we recommend
that you have them cleaned by a professional cleaning company.
Note
Please make sure you close any velcro fasteners on your clothing, as
these could otherwise damage the upholstery.
Applies to vehicles: with leather upholsteryNatural leather
Audi does everything possible to preserve the special
qualities of leather as a natural product.General notes
We have a wide selection of leathers. The main type used is nappa
in various forms, that is leather with a smooth surface in a selection
of colours.
The amount of dye used determines the appearance and properties
of leather. If the leather is left in a more natural state, it retains its
typical natural appearance and is pleasant and comfortable for the
seat occupants. Fine veins, healed scars, insect bites, wrinkles and
a subtle variation in shading remain visible; these are the character-
istic features of genuine natural leather.
Natural napped leather does not have a protective surface coating
of dye. It is therefore somewhat more prone to damage. You should
bear this in mind if children or pets often travel in the car, or if there
are other factors that could lead to damage.
Types of leather with a coloured surface coating are likely to be
more resistant to damage. This has a great advantage for day-to-day
use. However, this means that the typical natural characteristics of
the surface are less apparent, though this does not affect quality.
Cleaning and care
Because of the natural properties of the specially selected hides
employed, the finished leather has a certain sensitivity to grease
and dirt, etc. so a degree of care is required in everyday use and
when looking after the leather. Dark clothing (especially if damp or
incorrectly dyed) may stain leather upholstery. Dust and grit in the
pores and seams can have an abrasive effect and damage the
surface of the leather. Therefore leather should be cleaned at
regular intervals, depending on the actual amount of use. When
they have been in use for a certain time, your car seats will acquire

Technical data a typical and distinctive patina. This is characteristic for real leather
upholstery, and is a sign of genuine quality.
To maintain the value of natural leather you should note the
following points:
Caution
•
Avoid exposing leather to direct sunlight for long periods, other-
wise it may tend to lose some of its colour. If the car is left for a
prolonged period in the bright sun, it is best to cover the leather.
•
Sharp-edged objects on clothing, such as belts, zip fasteners,
rivets or similar, can also leave permanent scratches and rough
marks on the surface of the leather.Note
•
Use a suitable impregnating cream with ultra-violet protection at
regular intervals and after cleaning. This cream will nourish and
moisturise the leather, keep it supple and able to breathe. In addi-
tion, it will also help to protect the surface of the leather.
•
Clean the leather every 2 to 3 months and remove fresh dirt as
necessary.
•
Remove stains from fresh ball-pen and other inks, lipstick, shoe
cream and similar stains as soon as possible.
•
Preserve the colour of the leather. A special coloured cream will
renew the colour of the leather when required and will eliminate
differences in colour.
Applies to vehicles: with leather upholsteryCleaning and care of leather upholstery
Natural leather requires an extra degree of attention and
care.Normal cleaning
– Moisten a cotton or woollen cloth with water and wipe
over the leather surfaces.
More stubborn dirt
– More stubborn dirt can be removed using a mild soap
solution (pure liquid soap: two tablespoons dissolved in
one litre of water).
– It is very important not to let the water soak through the
leather or penetrate into the seams.
– Then wipe off with a soft, dry cloth.
Removal of stains
– Remove fresh water-based stains such as coffee, tea,
juices, blood etc. with an absorbent cloth or kitchen roll,
dried-on stains with the cleaning agent from the care set.
– Remove fresh fat-based stains on the surface such as
butter, mayonnaise, chocolate, etc. with an absorbent
cloth or kitchen roll or with the cleaning agent from the
care set.
–Treat fat-based, dried-in stains with grease-dissolving
spray.
–Treat less common stains such as ball-pen and other
inks, felt-tip pens, nail polish, dispersion paint, shoe
cream etc. with a special leather stain remover.

Technical data If a lot of coolant has been lost, wait for the engine to cool down
before putting in cold coolant. Failure to do so could result in
serious engine damage.
WARNING
The coolant and coolant additive can be a health hazard. Store the
coolant additive in the original container in a safe place out of
reach of children – risk of poisoning.
For the sake of the environment
Drained off coolant should not be used again. Drain off the used
coolant into a suitable container and dispose of it in the proper
manner (observe environmental regulations).Radiator fan
The radiator fan can start running spontaneously.The radiator fan is powered electrically. The speed of the fan is
varied according to the temperature registered by a thermostat.
The radiator fan or auxiliary fan can continue to run for as long as
10 minutes after stopping the engine – even after the ignition is
switched off. It may also start running suddenly after a while if•
residual heat raises the coolant temperature, or
•
the hot engine compartment is additionally heated up by the
sun.
Brake fluidNote
When required, the brake fluid should be changed by a
competent mechanic with the proper equipment.Brake fluid gradually absorbs moisture from the atmosphere. If the
water content in the brake fluid is too high, this may cause corrosion
in the brake system over time. In addition, the boiling point of the
brake fluid will be considerably reduced. This could adversely affect
the braking ability in certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has
to be changed.
The brake fluid is replaced by your Audi R8 dealer as part of the
Inspection Service. They are familiar with the procedure and have
the necessary special tools and spare parts as well as the proper
facilities for disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Qualified
workshops know that the brake fluid “DOT 4” is approved by Audi.
The brake fluid must be fresh and unused.
WARNING
Heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This would seriously affect the
efficiency of the brakes and the safety of the car – risk of
accident.

Checking and topping up fluids 162BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is located behind the cover in the luggage compart-
ment. To remove the cover, slide it to the left and lift it out.
The battery is virtually maintenance-free and is checked in the
Inspection Services.
We recommend that you replace a battery once it is older than 5
years.
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will
become inoperative (e.g. electric windows). These functions will
require resetting after the battery is reconnected. For this reason,
the battery should only be disconnected from the vehicle's electrical
system when absolutely necessary.
If the vehicle is not used for long periods
The battery will gradually lose its charge because certain electrical
equipment continues to draw current even when the ignition is off.
If you park the vehicle for long periods of time in winter you should
have your Audi R8 dealer take the battery out of the vehicle and keep
it in a frost-proof room. This ensures that it cannot “freeze up” and
be damaged. At warm outside temperatures it is sufficient to
disconnect the negative terminal of the battery. Even when the
battery is not connected you should charge it from time to time.
Winter conditions
The battery is drained more in cold weather, which means that the
starting power is reduced. For this reason, have the battery checked
and charged if necessary before the start of winter.Replacing the battery
A replacement battery must have the same capacity, voltage and
current rating. It must also have the same dimensions as the orig-
inal, factory-fitted battery and have sealed caps. The Audi batteries
which have been specially developed fulfil the maintenance,
performance and safety specifications for your vehicle.
We recommend to use only maintenance-free batteries or deep-
cycle resistant and leakproof batteries which comply with the
standards TL 825 06 (dated December 1997 or later) and VW 7 50 73
(August 2001 or later).
Since the battery is difficult to access, we recommend having it
replaced by an Audi R8 dealer or qualified workshop.
WARNING
•
All work on batteries requires specialist knowledge. For queries
regarding the vehicle battery please contact an Audi R8 dealership
or other qualified workshop (risk of chemical burns / risk of explo-
sion).
•
The battery must not be opened. Do not attempt to make any
changes to the electrolyte level of the battery. Otherwise, there is
a risk that a mixture of oxygen and hydrogen gas can accumulate
and cause an explosion.Caution
•
The battery holder and clamps must always be correctly secured.
•
Before starting any work on the battery, always observe the
warnings listed under ⇒ in “Important safety warnings for
handling a car battery” on page 163.For the sake of the environment
 Batteries contain toxic substances including sulphuric acid and
lead. They must be disposed of appropriately and must not be put
together with ordinary household waste. Make sure the battery
