WARNING
Sitting out of position increases the risk of severe injuries.•
Sitting out of position exposes the occupants to potentially
fatal injuries: if the airbags inflate they can strike any occupant
who is not in one of the designed seat positions.
•
Before starting a trip, sit in the correct position and stay in this
position as long as the vehicle is moving. Before every trip, make
sure all passengers are sitting in the correct positions and remain
correctly seated at all times ⇒page 67, “Seats and storage”.
Pedal are aPedal s
The pedals must always be free to move and must never
be obstructed by floor mats or any objects in the footwell.– Make sure that the accelerator, brake and clutch pedals
are not obstructed and can be pressed all the way down
to the floor.
– Make sure that all pedals are able to return freely to their
original positions.Only use floor mats which leave the pedal area free and can be
securely fastened in the footwell.
If one of the brake circuits should fail, increased brake pedal travel
will be required to bring the vehicle safely to a stop.
WARNING
Any obstructions that restrict pedal travel can cause loss of
vehicle control and critical situations in traffic.•
Never place objects in the driver's footwell. Such objects could
move under the pedals and interfere with their proper function. In
the event of sudden braking or a change of direction, you would
not be able to use the pedals. This could result in a loss of control
and possibly cause an accident.
Floor mats on the driver's side
Use only floor mats which can be securely fastened in the
footwell and do not obstruct the pedals.– Make sure that floor mats are securely fastened and
cannot interfere with the pedals ⇒.

Safe driving 108Use only floor mats that leave the pedal area unobstructed and are
firmly secured to prevent them from slipping. You can obtain suit-
able floor mats from your dealer or a specialist retailer.
WARNING
Any obstructions that restrict pedal travel can cause loss of
vehicle control and increase the risk of serious personal injury. •
Always make sure that floor mats are properly secured.
•
Never lay or install additional floor mats or other floor cover-
ings over the existing floor mats; this would restrict the pedal area
and possibly obstruct the pedals, which could cause an
accident.
Stowing luggage safelyNotes
All luggage and objects must be securely stowed.Loose items can cause a safety hazard or impair the handling of the
vehicle by changing the weight distribution.
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
•
Always stow objects in the luggage compartment.
•
Transporting heavy objects may affect the vehicle's handling by
shifting the centre of gravity – this could cause an accident. Take
extra care when driving and adjust your speed accordingly.
•
Never exceed the maximum axle loads or the maximum gross
weight for the vehicle ⇒page 198, “Performance, weights and
dimensions”. Exceeding the permitted axle loads or gross weight
limit can affect the vehicle's handling characteristics, and increase
the risk of accidents, personal injuries or damage to the vehicle.
•
Never leave your vehicle unattended when the luggage lid is
open. Children could climb into the luggage compartment and
close the luggage lid from the inside. In this case the child would
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 luggage 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 109.

Seat belts 112How to wear seat belts properlyPutting on the three-point seat belts
Always fasten your seat belts before driving off.– 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 across your chest and lap ⇒.
– Insert the latch plate into the buckle for the appropriate
seat and push it down until it is securely locked with an
audible click ⇒fig. 91.– Pull the belt to check that it is now securely fastened.
The three-point inertia reel belts are tensioned automatically. The
retractor system gives complete freedom of movement, as long as
the pull on the belt is slow. Hard braking locks the belt. The belt will
also lock when you accelerate, drive up or down a steep hill or in a
sharp curve.
WARNING
•
Always make certain that the belt is positioned properly
⇒fig. 90 – risk of injury ⇒page 112, “Adjusting the seat belts”.
•
The latch plate of the belt must always be engaged in the
correct buckle for that seat. Otherwise the belt will not be fully
effective and the danger of injury increases.
Adjusting the seat belts
Always position seat belts properly for maximum safety.Your vehicle is equipped to help you position the seat belt properly

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.

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

Wheels and tyres 170•
If wheel trims are fitted after the car is purchased, ensure that
there is an adequate flow of air for cooling the brakes.For the sake of the environment
Old tyres must be disposed of according to the laws in the country
concerned.
Note
•
Tyres with the “R0” mark are specially matched to your Audi. We
recommend that you use these tyres only. Your Audi R8 dealer or
specialist retailer will gladly provide you with further information.
•
Never mount used tyres if you are not sure of their previous
history.
•
For technical reasons it is not normally possible to use wheel
rims from other vehicles. In some cases this also applies to rims
from other vehicles of the same model.
Wheel bolts
The wheel bolts are designed to suit the rims on your car.The wheel bolts are matched to the rims. When installing different
wheels (for instance alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with the right length and
correctly shaped bolt heads. This is essential for the secure fit of the
wheels and for the proper function of the brake system.
Audi R8 dealers have full information on the technical requirements
when installing or changing tyres, rims or wheel trims.
The wheel bolts should be clean and turn easily.
A special adapter is required to turn the anti-theft wheel bolts*
⇒page 182.
Winter tyres
Winter tyres will significantly improve the car's handling
in winter road conditions.–Use only radial ply winter tyres.
– Winter tyres must be fitted on all four wheels.
– Only use winter tyres of the correct type approved for
your vehicle.
– Please note that the maximum permissible speed for
winter tyres may be lower than for summer tyres.
– Also note that winter tyres are no longer effective when
the tread is worn down.
– After fitting the wheels you must always check the tyre
pressures. The correct tyre pressures are listed on the
sticker on the driver's door pillar ⇒page 167.In winter road conditions winter tyres will considerably improve the
car's handling. Due to their type of construction (width, rubber
compound, tread pattern), summer tyres give less grip on ice and
snow. This applies particularly to vehicles equipped with wide
section tyres or high speed tyres (code letters H, V or Y on the side-
wall).
Only use winter tyres of the correct type approved for your vehicle.
The sizes of the winter tyres approved for your vehicle are listed in
the vehicle's documents (e.g. EC Certificate of Conformity or COC
document
3)). The vehicle documents vary depending on the
country of residence. Also refer to ⇒page 168.
Winter tyres are no longer fully effective when the tread is worn
down to a depth of 4 mm.

should be at least 1.8 bar.
– Switch off the compressor by moving switch to
position0. If the necessary tyre pressure of at least 1.8
bar is not reached this means that the tyre cannot be
repaired using the tyre sealant. You should obtain profes-
sional assistance.
Dismantling the Tyre Mobility System
– Remove the filler hose from the valve and pull the
connector out of the socket.
– Screw the dust cap onto the valve.
– Put the empty tyre sealant can back into its original pack-
aging and then secure it in the holder under the floor
panel in such a way that it will not leak.
– Then drive away immediately so that the tyre sealant can
spread evenly in the tyre.
WARNING
•
Please observe the manufacturers' safety notes on the stickers
on the compressor and the tyre sealant can.
•
If it was not possible to build up a tyre pressure of 1.8 bar
within 5 minutes this means that the tyre is too badly damaged.
Do not drive on.
•
Seek professional assistance if the repair of a tyre puncture is
not possible with the sealing compound.
