Checking and topping up fluids 158
Checking oil level
– Warm up the engine by driving the vehicle until the oil
temperature shown in the instrument cluster is between
100 °C and 110 °C ⇒page 157, fig. 117.
– Park your vehicle on a level surface.
– Allow the warm engine to run for about two minutes at
idling speed.
– Switch off the engine and wait for two minutes.
– Check the oil level using the dipstick ⇒page 157,
fig. 118.
Oil level in area
–Do not top up oil.
Oil level in area
– Add 1 litre of oil ⇒page 158. After topping up the oil level
should be in area .Depending on how you drive and the conditions in which the car is
used, oil consumption can be up to 1.0 ltr./1000 km. Oil consump-
tion is likely to be higher for the first 5000 km.
Topping up the engine oil

–Unscrew cap

from oil filler opening ⇒fig. 119.
– Top up carefully using the correct oil ⇒page 198.
– Check the oil level again ⇒page 157.
– Top up with oil if necessary.
– Replace the oil filler cap carefully and push the dipstick
all the way in.
WARNING
•
Ensure that no oil comes into contact with hot engine compo-
nents when topping up: this could cause a fire.
•
Wash your skin thoroughly if it comes into contact with engine
oil.Caution
•
The oil level must never be above area , as this may result in
damage to the catalytic converter or to the engine. Contact a quali-
fied workshop to extract the engine oil if necessary.

Technical data
•
No additives should be used with engine oil. Any damage caused
by the use of such additives would not be covered by the factory
warranty.For the sake of the environment
•
Never pour oil down drains or into the ground.
•
Always observe statutory requirements when disposing of
empty oil canisters.
Cooling systemCoolant
The purpose of the coolant is to carry heat away from the
engine. The correct amount of anti-freeze is important to
prevent the cooling system from freezing in winter.The cooling system is filled for life at the factory, so the coolant does
not need to be changed. The coolant consists of a mixture of water
and anti-freeze additive G12++. This is a glycol-based anti-freeze
with anti-corrosion additives.
Anti-freeze additive
The amount of anti-freeze additive required depends on the temper-
atures to be expected in the winter season. If the anti-freeze concen-
tration is too low the coolant can freeze, resulting in failure of the
cooling system and heater.
The cooling system is filled at the factory with the correct amount of
anti-freeze for the country concerned.
In most cases the mixture consists of 60% water and 40% additive.
This mixture gives the required anti-freeze protection at tempera-
tures down to – 25 °C and protects the alloy parts of the cooling
system against corrosion. It also prevents scaling and raises the
boiling point of the coolant.Countries with warm climate
The coolant concentration must not be reduced by adding plain
water, even in the summer or in warm climates. The concentration
of the anti-freeze additive must always be at least 40%.
Countries with cold climate
If greater anti-freeze protection is required in very cold climates, the
proportion of the anti-freeze additive G12++ can be increased. A
concentration of 60% offers protection down to about -40 °C. The
concentration of the anti-freeze additive must not be more than
60%, otherwise this would reduce the anti-freeze protection. In addi-
tion, the cooling effect will be adversely affected.
Vehicles for export to countries with a cold climate (such as Sweden,
Norway and Finland) are supplied with antifreeze protection down
to about -35 °C. The concentration of the antifreeze additive for
these countries should always be at least 50%.
Caution
•
It is advisable to have the cooling system checked before the
winter season to make sure that the anti-freeze concentration is
adequate for the conditions to be expected. This applies particularly
if you intend to take the car into a colder climate zone. If necessary,
have the anti-freeze concentration increased to 50 - 60% as required.
•
Use only antifreeze additive G12++, an additive meeting the
specification “TL-VW 774G”. Other additives may give considerably
inferior corrosion protection. The resulting corrosion in the cooling
system can lead to a loss of coolant, causing serious damage to the
engine.
•
The coolant additive G12++ must not be mixed with any other
additives.

Checking and topping up fluids 160Checking coolant level
Be careful when checking the coolant.– Switch off the ignition.
– Cover the cap on the expansion tank with a cloth, and
carefully unscrew the cap anti-clockwise ⇒.
– Read off the coolant level on the inside of the radiator
expansion tank ⇒fig. 120. When the engine is cold it
must be above the “min” mark. When the engine is hot it
may be slightly above the marked area.The expansion tank is located in the engine compartment on the
right. Its location is also shown in the illustration of the engine
compartment ⇒page 156.
The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp in the instrument
cluster ⇒page 35. However, we recommend that it should be
checked occasionally.
Coolant losses
Any loss of coolant normally indicates a leak in the cooling system.
In this case the cooling system should be inspected by a qualified workshop without delay. It is not sufficient merely to top up the
coolant.
If there are no leaks in the system, a loss of coolant can only occur
if the coolant boils and is forced out of the system as a result of
overheating.
WARNING
•
The cooling system is under pressure. Do not unscrew the cap
on the expansion tank when the engine is hot: you could be
scalded by escaping steam
•
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.Caution
Radiator sealants must not be added to the coolant. Such additives
could seriously impair the function of the cooling system.Topping up the coolant– Add coolant.
– Turn the cap clockwise until it engages.Make sure that the coolant meets the required specifications
⇒page 159, “Coolant”. Do not use a different type of additive if anti-
freeze additive G12++ is not available. In this case use only water
and bring the coolant concentration back up to the correct level as
soon as possible by putting in the specified additive.
Always top up with fresh, unused coolant.
Fill up only to the top edge of the marked area. Excess coolant is
forced out of the system through the valve in the filler cap when the
engine gets hot.

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.

Note•
Do not use the compressor for longer than 8 minutes at a time,
as it could overheat. When the compressor has cooled down, you
can use it again.
•
If tyre sealant should leak out, leave it to dry and then pull it off
like foil.
Final checkAfter covering a short distance it is necessary to check the
tyre pressure
– After about 10 minutes stop to check the tyre pressure.
– If tyre pressure is still at least 1.3 bar, pump the tyre up
to the pressure specified (see driver's door pillar) and
drive to the nearest workshop to have the tyre and the
tyre sealant can replaced.
– If tyre pressure is less than 1.3 bar, the tyre is too badly
damaged. Do not drive on. You should obtain profes-
sional assistance.
WARNING
If tyre pressure is less than 1.3 bar after driving about 10 minutes,
the tyre is too badly damaged. Do not drive on. You should obtain
professional assistance.
Note
After carrying out repairs to a tyre, have the tyre sealant can
replaced by a qualified dealer. This will ensure that the Tyre Mobility
System is operative again.
Changing a wheelTyres with directional tread pattern
Tyres with directional tread pattern must be mounted so
that they rotate in the correct direction.A directional tread pattern is identified by arrows on the sidewall
pointing in the forward running direction. Always note the direction
of rotation indicated when mounting the wheel. This is important so
that these tyres can give maximum grip and avoid excessive noise,
tread wear and aquaplaning.Applies to vehicles: with anti-theft wheel boltsAnti-theft wheel bolts
A special adapter is required to turn the anti-theft wheel
bolts.– Insert the adapter completely into the anti-theft wheel
bolt .
