2007 AUDI R8 engine overheat

Your vehicle and the environment 138Your vehicle and the environmentRunning inA new vehicle should be run in over a distance of 2,500 km. During
the first 1,000 km do not use full throttle and do not exceed an
engine speed of 6,000 rpm. From 1,000 to 2,000 km you should also
avoid using full throttle. From 2,000 to 2,500 km you can then
increase engine speed gradually and briefly to 8,250 rpm.
During its first few hours of running, the internal friction in the
engine is greater than later on when all the moving parts have
bedded down.
How the vehicle is driven for the first 2,500 km also influences the
engine quality. After the first 2,500 km you should continue driving
at moderate engine speeds, in particular when the engine is cold.
This helps to reduce wear and tear on the engine and increases the
potential mileage which can be covered by the engine.
You should also avoid driving with the engine speed too low.
Change down to a lower gear when the engine no longer runs
“smoothly”. Excessively high engine speeds are prevented by an
automatic rev limiter.Emission control systemsThe vehicle must only be used with unleaded petrol, otherwise the
catalytic converter will be destroyed.
Never run the tank completely dry. The irregular fuel supply can
cause misfiring, which would allow unburnt fuel to enter the
exhaust system, which could cause overheating and damage the
catalytic converter.
WARNING
•
Because of the high temperatures which can occur in the emis-
sion control system, do not park the vehicle where the exhaust
can come into contact with flammable materials under the car
(e.g. on grass or at the forest edge). - Fire hazard!
•
Do not apply any underseal agents in the area around the
exhaust system - fire hazard!
Driving abroadUnleaded petrol
A car with catalytic converter must not be run with leaded petrol
⇒page 138. Before driving abroad make sure that unleaded petrol
is available there.
Changing over headlight dip settings
The asymmetric low beams of the headlights are designed to light
up the near side of the road more intensely. If you drive in a country
where traffic drives on the opposite side of the road to the home
country, this will dazzle oncoming traffic.
The headlight dip settings must be changed to avoid dazzling
oncoming traffic. For safety reasons, you should have the dip
settings changed by a qualified workshop.
For further information about changing the dip settings on xenon*
headlights, please contact your Audi R8 dealer or other qualified
workshop.

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.
