WARNING
•
The diagonal part of the belt should never be positioned across 
the neck, but roughly over the centre of the shoulder; it should fit 
closely against the upper part of the body. The lap part of the belt 
must be worn tightly across the hips, and not over the abdomen 
⇒page 112, fig. 92. Pull the belt tight if necessary to take up any 
slack.
•
Always make sure that belt is positioned properly. Incorrectly 
worn seat belts can give rise to injuries even in a minor collision.
•
Seat belts worn too loose can result in injuries because they 
allow excessive forward movement in a crash; the occupant will 
be brought to a sudden stop by the belt webbing.
Wearing and adjusting the seat belts during pregnancy
To afford the best protection for the unborn child it is 
important for the mother to wear the seat belt properly at 
all times.Women should always ensure they adjust the seat belt 
correctly during pregnancy.– Adjust the front seat and head restraint correctly before 
putting on the seat belt ⇒page 67, “Seats and storage”.
– To fasten the belt, take hold of the latch plate and pull it 
slowly down across your chest. Wear the lap portion of 
the seat belt as low as possible over the hips so that there 
is no pressure on the stomach ⇒fig. 93, ⇒.
– Insert the latch plate into the buckle for the appropriate 
seat and push it down until it is securely locked with an 
audible click ⇒page 112, fig. 91.
– Pull the belt to check that it is now securely fastened.
WARNING
During pregnancy, women should especially make sure to wear 
the lap portion of the seat belt as low as possible across the hips 
so that there is no pressure on the stomach.Taking off the seat belts
The red button releases the belt from the buckle.– Press the red button in the seat belt buckle ⇒fig. 94. The 
latch plate will spring out of the buckle.

Airbag system 116•
If you sell the vehicle, please remember to pass on the 
complete Service Wallet to the new owner. If the front passenger's 
airbag has been deactivated, it is important that the new owner is 
also given the relevant documents.
•
The relevant safety requirements must be observed when the 
vehicle or components of the airbag or belt tensioner systems are 
scrapped.
•
In an accident in which one or more airbags are triggered the 
alternator and the starter are - for safety reasons - both discon-
nected from the battery via a pyrotechnic circuit breaker.
−Any repairs to the pyrotechnic circuit breaker must always 
be performed by a qualified workshop (accident risk).
−The relevant safety requirements must be observed when 
the vehicle or the circuit breaker are scrapped.
When are the airbags triggered?
The airbag system is triggered in collisions with a severe 
impact.The airbag system is designed so that the airbags for the driver and 
front passenger are triggered in a severe frontal collision.
In severe side collisions the side airbags are triggered on the impact 
side of the vehicle.
In certain types of accident the front airbags and the side airbags 
may be triggered together.
The airbag system is not triggered in minor frontal or side collisions, 
or in rear collisions or if the car overturns. In these situations the 
occupants are protected by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering response of the 
airbag system in all possible situations, since the circumstances in different types of accident will vary considerably. Important factors 
include, for example, the nature (hard or soft) of the object which 
the car hits, the angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends primarily on the vehicle 
deceleration rate resulting from the collision. By processing the 
signals from the sensors located in the vehicle, the electronic 
control unit is immediately able to evaluate the severity of the colli-
sion and activate the restraint systems accordingly. If the decelera-
tion rate is below the predefined reference value in the control unit 
the airbags will not be triggered, even though the accident may 
cause extensive damage to the car.
Note
The airbag releases a fine dust when it inflates. This is quite normal 
and does not mean there is a fire in the vehicle.Front airbagsDescription of front airbags
The airbag system is not a substitute for the seat belts.

Child safety 122Child safetyPoints to remember if children are 
travelling in the carIntroductionThe physical principles involved and the forces acting in a collision 
apply to children just as much as adults ⇒page 110, “Forces acting 
in a collision”. But, unlike adults, children do not have fully devel-
oped muscle and bone structures. This means that children are 
subject to a greater risk of injury.
To reduce this risk, children must always use special child restraint 
systems when travelling in the car.
Use only child restraint systems which are officially approved under 
the European standard ECE R 44 and are suitable for the child. ECE R 
refers to the Economic Commission of Europe Recommendation, 
which categorises child restraint systems in 5 groups ⇒page 123, 
“Child seat categories”. Child restraints that have been tested and 
approved under the ECE R 44 standard bear the ECE-R 44 test mark 
on the seat (the letter E in a circle with the test number below it).
We recommend using child restraint systems from the range of 
Audi Genuine Accessories available from Audi R8 dealers. The 
“Huckepack” range includes suitable restraint systems for all ages. 
These systems have been specially designed for use in Audi vehicles 
and comply with the ECE R 44 standard.
Follow the manufacturer's instructions and observe any statutory 
requirements when installing and using child restraints ⇒ in 
“Important safety notes for using child safety seats”.
Important safety notes for using child safety seats
Correct use of child safety seats can help to reduce the 
risk of injury in an accident.
WARNING
•
All vehicle occupants, especially children, must wear a seat 
belt while the vehicle is in motion.
•
Children who are less than 1.5 metres tall must not wear a 
normal seat belt without a child restraint, as this could cause inju-
ries to the abdominal and neck areas.
•
Babies and children must never travel on another occupant's 
lap.
•
A suitable child safety seat can protect your child ⇒page 123, 
“Child safety seats”.
•
Never allow two children to occupy one child safety seat.
•
Never leave a child without supervision in a child safety seat.
•
Never allow a child to travel in the car without a suitable child 
restraint.
•
Never allow a child to stand up or kneel on a seat while the car 
is moving. In an accident, the child could be catapulted through 
the car, causing possibly fatal injuries to itself and other occu-
pants.
•
If children lean forward or are otherwise out of position when 
the car is moving, they are at greater risk of injury in an accident. 
This is especially the case if the airbag is activated during an acci-
dent. There is then a risk of serious or potentially fatal injury.
•
To ensure proper protection, it is important to wear the seat 
belts in the correct position ⇒page 112, “How to wear seat belts 
properly”. Always check that the belt is properly positioned

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.

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

Intelligent technology 136front wheels is not obstructed, otherwise the brakes can overheat. Power steeringThe power steering assists the driver when turning the 
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed 
to turn the steering wheel.
The power steering does not function when the engine is switched 
off. In this case the steering wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary, 
this will place an excessive load on the power steering system. In 
this case, the power steering system will make noises. It will also 
reduce the idling speed of the engine.
Caution
Do not keep the steering in the full-lock position for longer than 
15 seconds when the engine is running – this could cause damage 
to the power steering system.
Note
•
If the power steering should fail at any time or the engine is 
switched off (for instance when being towed), the car can still be 
steered. However, more effort will be required to turn the steering 
wheel.
•
If the system is leaking or malfunctioning, please take the car to 
a qualified workshop as soon as possible.
•
The power steering requires a special hydraulic fluid. The 
container for the fluid is located in the engine compartment. The 
correct fluid level in the reservoir is important for the power 
steering to function properly. The hydraulic fluid level is checked at 
the Inspection Service.
Four-wheel drive (quattro®)On quattro models the engine power is distributed to all 
four wheelsGeneral notes
On four-wheel drive vehicles, the engine power is distributed to all 
four wheels. The distribution of power is controlled automatically 
according to your driving style and the road conditions. Also refer 
to ⇒page 132.
Winter tyres
Thanks to its four-wheel drive, your car will have plenty of traction 
in winter conditions, even with the standard tyres. Nevertheless, we 
still recommend that winter tyres should be fitted on all four wheels 
when winter road conditions are expected, mainly because this will 
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars 
with four-wheel drive ⇒page 171, “Snow chains”.
Replacing tyres
The dimensions of the wheels and tyres used on four-wheel drive 
vehicles must comply with the manufacturer's specifications 
⇒page 168, “Replacing wheels and tyres”.
WARNING
•
Even with four-wheel drive, you should always adjust your 
speed to suit the conditions. Do not let the extra safety provided 
tempt you into taking any risks when driving – this can cause acci-
dents.
•
The braking ability of your car is limited by the grip of the tyres. 
In this respect, your car is no different from a car without four-
wheel drive. So do not be tempted to drive too fast on icy or slip-

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.

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
