Driver information system 38The message disappears after 5 seconds. Press the adjuster/test
button ⇒page 10, fig. 2 briefly if you wish to call up the message
again.
If the display indicates that one of the lights is not working, this can
have a number of causes:•
Bulb failure ⇒page 193.
•
A “blown” fuse ⇒page 190, “Changing fuses”.
•
Defective electrical wiring.
Have the components replaced or the wiring repaired as necessary
by a qualified workshop.
WARNING
•
Bulbs are sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
Incorrect handling of the high-voltage element of xenon gas-
discharge bulbs can have potentially fatal consequences.
Brake light failure
If the symbol
or the text BRAKE LIGHT lights up, check the
following components:
•
Brake light bulbs
•
Wiring connections
•
Brake light switch
Have the components repaired or replaced by a qualified workshop.Note
The brake light switch is only tested during the initial systems check
after starting the engine.
Applies to vehicles: with light sensor/ rain sensorLight sensor/rain sensor
This indicator lamp comes on if the automatic headlights/
automatic wipers are defective.If the
symbol appears, this means that the light sensor/ rain
sensor is not functioning. For safety reasons, the dipped beam
headlights will then be switched on permanently when the light
switch is set to the AUTO position. However, you can still switch the
lights on and off in the normal way with the light switch. If the rain
sensor is defective, the functions operated via the windscreen wiper
lever will still be available. You should have the light sensor/ rain
sensor checked by a qualified workshop as soon as possible.
Applies to vehicles: with R tronicSelector lever defective
and
Selector lever defective! No R gear!
If these symbols light up, there is a fault in the R tronic selector
lever. The indicators on the selector lever will go out or flash. It is no
longer possible to engage reverse gear. If you were using the
gearbox in manual mode, it will switch back to automatic mode.
You can continue to change gear manually. Starting in neutral (N),
pull the paddle lever on the steering wheel to engage first gear.
The gearbox will now remain in manual mode and you can select the
gears using the paddle levers.

Fuses and bulbs 190Fuses and bulbsFusesChanging fuses
If a fuse has blown it must be replaced.The various electrical circuits are protected by fuses. The
fuses are located behind a cover in the passenger's foot-
well.
– Switch off the ignition and the component concerned.
– Remove the floor mat.
– Fold out the foot rest ⇒fig. 133.
– Identify the fuse for the failed component ⇒page 190,
“Fuse list”.
– Take the plastic clip from inside the fuse box, fit it onto
the blown fuse, and pull the fuse out.
– Replace the blown fuse (which will have a melted metal
strip) with a new fuse of the same amp rating.
– Fold the foot rest back into place.Caution
Never attempt to “repair” a fuse or replace it by fitting a fuse with a
higher rating - risk of fire! It could also cause damage to other parts
of the electrical system.
Note
•
If a newly replaced fuse blows again after a short time, the elec-
trical system must be checked by a qualified workshop as soon as
possible.
•
It is advisable to carry several spare fuses at all times. They are
available from Audi R8 dealers and specialist retailers.

The vehicle data sticker ⇒page 196, fig. 135 is located together with
the fuses in the passenger's footwell ⇒page 190. One section of the
vehicle data sticker is attached to the inside cover of the Service
Schedule before the vehicle is handed over.
The sticker lists the following data:
Vehicle identification number (chassis number)
Vehicle type / engine power / gearbox type
Engine and gearbox code letters
Paint No. / Interior equipment No.
Optional equipment codes
Fuel consumption and emissions
Fuel consumption and emissions
Information on the vehicle's fuel consumption and emissions is
given at the bottom of the vehicle data sticker :
Urban cycle consumption (ltr./100 km)
Extra-urban cycle consumption (ltr./100 km)
Combined cycle consumption (ltr./100 km)
Combined CO
2 emissions (g/km)
The specified values were determined in accordance with the test
procedure prescribed by the currently applicable version of
Directive 80/1268/EEC. The specifications do not refer to an indi-
vidual vehicle. Other consumption figures may be achieved during
normal driving, depending on special equipment fitted, vehicle
loading, personal driving style, road and traffic conditions, environ-
mental factors and the condition of the car.
