Lights and vision 60The windscreen washer jets are heated when the ignition is
switched on.
When the lights are switched on you should only pull the lever
briefly to wash the windscreen, otherwise the headlight washers
will also be activated. This will use an unnecessary amount of fluid
from the reservoir.
WARNING
•
Poor visibility can cause accidents. Always ensure that the
wiper blades are in good condition ⇒page 62, “Changing wiper
blades”.
•
The light sensor/ rain sensor* is only intended to assist the
driver. The driver is still obliged to manually operate the wind-
screen wipers and the lights as required depending on visibility.
•
Do not use water-repellent coatings on the windscreen. In bad
visibility conditions such as light rain, low sun or when driving at
night these coatings can cause increased dazzle, which is a
serious safety hazard. Such coatings can also cause the wiper
blades to judder.Caution
•
In icy conditions, always check that the wiper blades are not
frozen to the glass before using the wiper for the first time. If you
switch on the wipers when the wiper blades are frozen to the glass,
this could damage both the wiper blades and the wiper motor.
•
Make sure you switch off the windscreen wiper system (lever in
position "0") before you use an automatic car wash. This will avoid
inadvertent triggering of the wipers and possible damage to the
wiper system.Note
•
Check that the washer fluid reservoir is full before starting a long
journey. Filling the reservoir ⇒page 164.
•
Worn or dirty wiper blades can cause smearing on the glass
which can also impair the effectiveness of the light sensor/ rain
sensor*. Please check the wiper blades regularly.
•
If you leave the windscreen wiper lever set to the intermittent
wipe function when the ignition is switched off, the light sensor/
rain sensor* will not be activated until you reach a road speed of at
least 6 km/h.
•
Applies to vehicles with light sensor/ rain sensor: If the wind-
screen wipers have been activated manually and it is raining, the
automatic headlights* will come on ⇒page 53, “Automatic (sensor-
controlled) headlights”. In the daytime the headlights will automat-
ically go off again once the wipers are switched off. The automatic
headlights* function is only available if the light switch is in the
“AUTO” position ⇒page 53, fig. 47.
Headlight washer systemWith the lights switched on, operate the automatic wind-
screen wash and wipe ⇒page 59, fig. 54 , and keep the
lever pulled towards you for at least 1 second.The headlight washer jets come out of the bumper automatically
(under water pressure).
Clean off stubborn dirt (insects, etc.) from the lenses at regular
intervals, for instance when stopping for fuel.
To ensure that the system works properly in winter, keep the nozzle
holders free of snow and remove any ice with a de-icer spray.

Technical data When driving through a tunnel or in queues of traffic, to prevent
fumes entering the interior of the vehicle.
WARNING
For reasons of safety you should not leave the air recirculation
switched on for too long. This mode prevents fresh air from
entering the vehicle, so the windows can mist over if the air
cooling is switched off. Bad visibility can cause an accident.AC mode Activating the AC mode
– Press the button ⇒page 75, fig. 69.
Deactivating the AC mode
– Press the button again.In the AC mode, the air cooling system is switched on and the
heating and ventilation are regulated automatically.
Note
If the LED in the AC button should continue to light up when the AC
mode has been switched off (i.e. the air conditioner has been
switched off) this is due to a defect in one of the air conditioner
components. If a malfunction should occur, please contact a quali-
fied workshop.
Economical operation of the air conditioner
Economical operation of the air conditioner will help to
save fuel.When the air conditioner is operating in the cooling mode it
reduces engine power and increases fuel consumption. To
ensure that the cooling mode is activated only when really
necessary, please note the following points:
– Switch the AC mode off if you wish to save fuel.
– Switch the AC mode off if you decide to open the
windows while driving.
– If the vehicle has heated up after standing in the sun,
open the windows and doors for a short time to cool the
vehicle.
For the sake of the environmentBy saving fuel you also reduce the amount of pollutants emitted
from your vehicle.Rear window heating

The rear window heating helps to demist the rear window.– Press the
 button ⇒page 75, fig. 69 to switch the rear
window heating on or off.
The rear window heating only works when the engine is running. An
indicator lamp in the button lights up when the rear window heater
is switched on.
The rear window heating switches off automatically after about
10 minutes.

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.

Fuel and filling the tank 152Fuel and filling the tankPetrolPetrol grade
The correct grade of petrol is listed inside the fuel tank
flap.The vehicle is equipped with a catalytic converter and must only be
run on unleaded petrol. Unleaded petrol must comply with the
European EN 228 standard. The petrol grades have different octane
ratings (RON). If, in exceptional circumstances, the correct octane
rating is not available, please note the following:
Your engine normally requires Super Plus unleaded petrol (98 RON).
Premium unleaded fuel with 95 RON can also be used. This can,
however, result in a slight loss of power under certain driving condi-
tions. If premium unleaded petrol is not available, the engine can be
run on regular unleaded petrol with 91 RON as an emergency
measure. In this case only use moderate engine speeds and a light
throttle. Avoid using full throttle. Fill up with premium or Super Plus
petrol as soon as possible.
Caution
•
Petrol complying with the EN 228 standard can contain small
quantities of ethanol. However, “bioethanol fuels”, which are
retailed under various different names such as E50 and E85, and
which contain a large proportion of ethanol, must not be put into
the vehicle, as this would damage the fuel system.
•
Even one tankful of leaded fuel would permanently impair the
efficiency of the catalytic converter.
•
High engine speed and full throttle can damage the engine when
using petrol with an octane rating lower than the correct grade for
the engine.
