http://www.fairbimbofix.comPossible alternatives for securing a child safety seat
A child safety seat can be secured on the passenger's
seat.The following alternatives are available for safely securing a child
safety seat on the passenger seat:•
Child safety seats of the categories 0 to 3 can be secured with the
standard three-point seat belts.

Child safety seats of the categories 0, 0+ and 1 with the “ISOFIX”
system can be secured without seat belts using the “ISOFIX”
retainers ⇒page 128.
Compatibility of vehicle seat positions for child safety seats
(according to EC directive 77/541):u “universally compatible”
a The front passenger's backrest must be set as far forward as
possible or adapted to the child safety seat as required, and the
seat height must be adjusted to its highest position.
b The front passenger's seat can be equipped with optional
“ISOFIX” retainers (this does not apply to bucket seats).
c The front passenger's airbag must be deactivated if a rearward-
facing child seat is used.
WARNING
While the vehicle is moving, children must always be protected
with a restraint system which is suited to their age, height and
weight. Please refer to the chapter “Child seat categories”.•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been

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.

Technical data We ar
The rate of wear on the brake pads depends a great deal on how you
drive and the conditions in which the vehicle is operated. Negative
factors are, for instance, city traffic, frequent short trips or hard
driving with abrupt starts and stops.
Wet roads; road salt
When you are driving at a speed higher than 70 km/h and have the
windscreen wipers switched on (at or above intermittent setting 4)
the brake pads are very briefly brought into contact with the brake
discs. This automatic process which goes unnoticed by the driver is
carried out at regular intervals and is intended to improve braking
response in wet conditions.
In certain conditions, such as in heavy rain, or after washing the car
or driving through water, the full braking effect can be delayed by
moisture (or in winter by ice) on the discs and brake pads. The
brakes should be “dried” by pressing the pedal to restore full
braking effect.
The effectiveness of the brakes can also be temporarily reduced if
the car is driven for some distance without using the brakes when
there is a lot of salt on the road in winter. The layer of salt that accu-
mulates on the discs and pads can be removed with a few cautious
brake applications.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is used infrequently, or if
you only drive low mileages without using the brakes very much.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed ⇒.
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may
mean that one of the two brake circuits has failed. Drive immedi-
ately to the nearest qualified workshop and have the fault rectified. On the way to the dealer, be prepared to use more pressure on the
brake pedal and allow for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply to the brake pedal.
It only works when the engine is running.
WARNING

When applying the brakes to clean off deposits on the pads and
discs, select a clear, dry road. Be sure not to inconvenience or
endanger other road users; do not risk an accident.

Never let the car coast with the engine switched off (this can
cause accidents).Caution

Never let the brakes “drag” by leaving your foot on the pedal
when you do not really intend to brake. This overheats the brakes,
resulting in longer stopping distances and greater wear.

Before driving down a long, steep gradient, it is advisable to
reduce speed and select a lower gear. In this way you will make use
of the engine braking effect and relieve the load on the brakes. If you
still have to use the brakes, it is better to brake firmly at intervals
than to apply the brakes continuously.Note

If the brake servo is out of action due to a malfunction, or if the
car has to be towed, you will have to press the brake pedal consid-
erably harder to make up for the lack of servo assistance.

If you wish to equip the car with accessories such as a front
spoiler or wheel covers, it is important that the flow of air to the

Technical data pery roads just because the car still has good acceleration in these
conditions (accident risk).

On wet roads bear in mind that the front wheels may start to
“aquaplane” and lose contact with the road if the car is driven too
fast. If this should happen, there will be no sudden increase in
engine speed to warn the driver, as with a front-wheel drive car. So
do not drive too fast in the wet: adjust your speed to suit the
conditions (accident risk).
Dry sump lubrication systemLarge lateral and longitudinal forces act on the engine and vehicle
when a sporty driving style is adopted. A dry sump system ensures
that the engine continues to be supplied with oil and lubricated
optimally under these conditions.
In a “normal” car, the oil is stored in the oil sump and is pumped
from there to the lubrication points inside the engine. The oil then
flows from there back into the oil sump. In extreme situations this
can cause air to be sucked into the oil pump with the result that the
oil pressure is no longer high enough.
In a dry sump lubrication system, the oil is stored in a separate oil
tank instead of the oil sump (which is “dry”). While one pump sends
oil to the engine, a second pump returns the oil from the engine to
the oil tank. The tall and slim shape of the oil tank means that the oil
pressure can be kept constant even in extreme conditions.
In addition, the oil sump is much lower on vehicles with dry sump
lubrication. This means that the engine can also be arranged lower
down for a lower centre of gravity and improved handling.

Sporty drivingLetting the engine warm up and cool downYou can reduce the amount of wear and tear on your vehicle during
a sporty driving session simply by adopting a more restrained
driving style while the engine is warming up and cooling down.
You should allow the engine to warm up by keeping the engine
speed below 7000 rpm until the engine oil reaches at least 90 °C. In
addition, the tyres will not develop their full grip potential until they
have had a chance to warm up on the road.
Even though the engine continues to be cooled after you switch it
off, it is particularly important to give it time to cool down before
parking. The engine, brakes, exhaust system and gearbox will all
reach very high temperatures when you adopt a sporty driving style.
Before you park the vehicle, allow it to cool down to normal temper-
ature by driving at moderate rpm speeds for several miles.Driving on a racing circuitBefore you take your car out on a racing circuit, please ensure that
it is in perfect condition. You should check the tyre tread and brake
pads for wear. It's also a good idea to increase the tyre pressure by
0.3 bar.
The oil consumption may be slightly higher than “normal” when
driving on a racing circuit ⇒page 157.
You should always check your vehicle after driving hard. Are the
brake pads ok? Do you notice any problems with the tyres (e.g. tread
worn, blistering, etc.)? Are the air intakes free of leaves and
deposits? Is the oil level ok?
Your Audi R8 dealer will be glad to carry out an inspection before
and after you use the car on a racing circuit.
Note

Some racing circuits (e.g. with banked curves) can affect the
behaviour of the ESP.

Driving the car on a racing circuit places a heavy load on all parts
of the vehicle. This can result in increased wear and tear.

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).

The heating element for the rear window is located on the inner
side of the window. To avoid damaging the heating element, do not
put stickers on the inner side of the window.

Never use warm or hot water to remove snow and ice from
windows and mirrors. This could cause the glass to crack!
Rubber seals (weatherstrips)The weatherstrips on the doors, windows, engine lid and luggage
lid will remain pliable and last longer if they are occasionally treated
with a suitable care product (for example silicone spray). This will
also prevent premature ageing and leaks. The doors will be easier to
open as well. If they are kept pliable, the door seals will be less likely
to freeze up in the winter.WheelsThe wheels require regular attention to preserve their appearance.
It is important to remove road salt and brake dust by washing the
wheels at regular intervals, otherwise the finish will be impaired.
After washing, the wheels should only be cleaned with an "acid-
free" cleaning agent for alloy wheels. This is available from Audi R8
dealers and specialist retailers. Never leave the cleaning agent on
the rims for any longer than specified in the instructions before
rinsing it off. If the wheel cleaner fluid contains acid it can attack the
surfaces of the wheel bolts.
Car polish or other abrasive agents should not be used. If the
protective paint coating is damaged by stone chips etc., the
damaged area should be touched up immediately.
WARNING
Please note when cleaning the wheels that water, ice and road salt
can impair the effectiveness of the brakes – this can cause an
accident.Care of interiorPlastic parts and leatherettePlastic parts and leatherette can be cleaned with a damp cloth. If
this is not sufficient, plastic parts and leatherette should only be
treated with a special solvent-free plastic cleaner.Applies to vehicles: with carbon partsCarbon par tsThe carbon parts on your vehicle have a painted surface. They do
not need any special care and are cleaned just like plastic parts
⇒page 147.Textile covers and trim partsTextile covers and trim parts (e.g. seats, door trim) should be
cleaned regularly with a vacuum cleaner. This will remove surface
dirt which could otherwise be rubbed into the textile material
during use. Do not use steam cleaners, as the steam could carry the
dirt deeper into the textile material.
Normal cleaning
We recommend that you use a soft sponge or lint-free, micro-fibre
cloth for normal cleaning. Only use brushes on floor coverings and
mats, as other textile surfaces could become damaged.

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.
