The needles on the dials in the instrument cluster are illuminated
when the ignition is switched on. The main instrument lighting (for
the dials and needles) comes on when the vehicle's lights are
switched on.
Engine oil temperature gaugeThe engine oil temperature gauge ⇒fig. 2 only works when the igni-
tion is switched on. In order to avoid possible damage to the engine,
please read the following notes for the different temperature
ranges.
Engine cold
If the needle is still in the lower range of the dial, this indicates that
the engine oil has not yet reached operating temperature. Avoid
high engine speeds, full acceleration and heavy engine loads.
Normal temperature
In normal operation the needle will settle somewhere in the centre
of the dial once the engine has reached operating temperature. The
needle may also go further up when the engine is working hard at
high outside temperatures. This is no cause for concern provided
the warning lamp

in the display does not start flashing.
Warning lamp

If the symbol

in the display flashes, either the engine oil temper-
ature is too high, or the engine oil level is too low ⇒page 157.
If the needle is at the top end of the dial, this means the engine oil
temperature is too high. Stop the vehicle, switch off the engine and
wait for it to cool down. If the warning lamp starts flashing again
after just a short distance, contact a qualified workshop.

When the ignition is switched on, the security programming of the
ignition key is verified electronically.
If an uncoded key is used, SAFE will appear continuously in the trip
recorder display. The vehicle cannot then be driven ⇒page 42.Voltmeter displayThe voltmeter indicates the voltage of the vehicle's electrical
system. The voltage of the electrical system should normally be
between 12 and 14 volts. If the display drops below 12 volts when
the engine is running, have the power supply (battery and alter-
nator) checked by a qualified workshop.
Note
The voltage may drop below 8 volts while the engine is being

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

bolt
5).
– Grip the box spanner as close to the end as possible and
tighten the bolt firmly by turning clockwise.
Have the tightening torque of the wheel bolts checked as soon as
possible with a torque wrench. The correct tightening torque is
120 Nm.
The inflation pressure must be checked as soon as possible.
Put the tools and jack back in the luggage compartment.
WARNING
The wheel bolts must not be loosened – this would cause a safety
risk.
Note
•
Do not use the hexagonal socket in the screwdriver handle to
loosen or tighten the wheel bolts.
•
If you notice that the wheel bolts are corroded and difficult to
turn, they must be replaced before having the tightening torque
checked.
•
In the interest of safety, drive at moderate speeds until the tight-
ening torque of the wheel bolts has been checked.
Jump-startingBefore starting the engine
If necessary, the engine can be started by connecting it to
the battery of another vehicle.If the engine should ever fail to start because of a discharged
battery, the battery can be connected to the battery of another
vehicle to start the engine. Suitable jump leads are required.
Both batteries must be rated at 12 Volts. The capacity (Ah) of the
booster battery should not be significantly lower than that of the
discharged battery.
Jump leads
The jump leads must be heavy enough to carry the starter current.
Refer to the details given by the manufacturer.
Only use jump leads with insulated battery clamps.
Positive cable – usually red
Negative cable – usually black
WARNING
•
When it is discharged the battery can freeze at temperatures
around 0°C. A frozen battery must first be thawed out before
connecting the jump leads, as it could otherwise explode.
•
Please note the safety warnings referring to working in the
engine compartment ⇒page 155.Note
•
There must be no contact between the two vehicles as otherwise
current could flow as soon as the positive terminals are connected.
•
The discharged battery must be properly connected to the
vehicle's electrical system.
5)An adapter is required to tighten the anti-theft wheel bolts ⇒page 182.
