2007 AUDI R8 key battery

Instruments and warning/indicator lamps 14Upper mileage recorder (trip recorder)
The upper mileage recorder shows the distance that has been trav-
elled since the trip recorder was last reset. It is used to measure indi-
vidual journeys. The last digit of the trip recorder indicates
distances of 100 metres or tenths of a mile. The trip recorder can be
reset to zero by pressing the reset button ⇒page 13, fig. 5.
When the ignition is switched off, the illumination of the mileage
recorder can be switched on for a few seconds by pressing the
adjuster/test button ⇒page 10, fig. 2 .
Fault display
If there is a fault in the instruments, the letters dEF appear perma-
nently in the trip recorder display. Please have the fault rectified as
soon as possible.
Immobiliser
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
started.

Replacing a key
If one of the keys has been lost, you should take the vehicle to an
Audi R8 dealer to have the remote control coding for that key deac-
tivated. For this purpose you should bring all available keys with
you.
It is also important to notify your insurance company if a key has
been lost.
Checking the key battery level
The indicator lamp ⇒fig. 33 lights up as soon as you press one of
the buttons. If the indicator lamp does not light up or flash, this
means the battery is exhausted and must be replaced.

WARNING
•
Always switch off the ignition and take the key with you when
leaving the vehicle - even if you only intend to be gone for a short
time. This is especially important if children are left in the car. They
might otherwise be able to start the engine or use power-operated
equipment such as the electric windows - this could lead to inju-
ries.
•
Wait for the vehicle to come to a standstill before removing the
ignition key from the lock. Otherwise the steering lock could
engage suddenly, causing an accident.

Remote control key
The remote control will lock and unlock the vehicle
without having to insert the key in the lock.The remote control transmitter and the battery are integrated in the
handle of the key. The receiver is in the interior of the vehicle. The
maximum range of the remote control depends on various factors.
The range is reduced when the battery starts to lose power.
If the receiver has been repaired or replaced, or if a replacement key
is used, the system will need re-programming by a qualified work-
shop. This is necessary so that the receiver can recognise your
remote control key.
The remote control keys (which are radio-operated) conform with all
relevant requirements for Germany and have been approved by the
Federal Approvals Office for Telecommunications of the Federal
Republic of Germany. All components are marked in accordance
with the current legal requirements. This certification forms the
basis for approval for use in other countries.
Personalised remote control key
When you switch off the ignition or lock the vehicle, the settings of
various convenience features are automatically stored and assigned
individually to the remote control key that is currently in use. The
settings stored for the remote control key are then recalled auto-
matically the next time the vehicle is unlocked, the door is opened
or the ignition is switched on.
Note
•
The remote control key is automatically deactivated when the
ignition is switched on.
•
The function of the remote control key may be impaired by inter-
ference from other nearby radio signals (for example from a mobile
telephone or TV transmitter) if these are in the same frequency
range.
Synchronisation
If the remote control fails to unlock the vehicle, it will be
necessary to re-synchronise the system.– Press the unlock button
 on the remote control.
– Use the key to manually unlock the driver's door within
30 seconds.
– Press the unlock
 or the lock button
.
Replacing the battery for the remote control key
Each remote control key contains a battery which is
located in the cover of the key.We recommend having the battery changed by a qualified
workshop if required. However, if you decide to change the
used battery yourself:
–Carefully prise apart the key ⇒fig. 34 and the cover
using a coin.
– Remove cover in the direction of the arrow.

– Take the used battery out of the cover.
– Insert the new battery. Make sure that the “+” symbol on
the battery is facing downwards. The correct polarity is
indicated on the cover.
– After inserting the battery, align the cover and key and
press the two parts together.
For the sake of the environmentUsed batteries must be disposed of appropriately and must not be
discarded with ordinary household waste.
Note
The new battery must be of the same type as the original one.Electronic immobiliser
The immobiliser is designed to prevent unauthorised
persons from driving the vehicle.An electronic chip inside the key automatically deactivates the
immobiliser when the ignition is switched on. When the ignition is
switched off after coming to a stop the electronic immobiliser is
activated automatically.
If an uncoded key is used, SAFE will appear continuously in the
mileage recorder display.
Note
•
The engine can only be started using an original Audi key with
the correct code.
•
It may not be possible to start the engine with the key if there is
another ignition key from a different make of vehicle on the same
key ring.
Central locking systemDescription
The central locking system allows both doors to be locked
and unlocked simultaneously.The central locking system on your vehicle locks and unlocks both
doors simultaneously.
The remote control key locks and unlocks the vehicle by means of a
radio signal ⇒page 43.
Locking and unlocking the vehicle using the key
In addition to the other functions, you can lock and unlock the
vehicle in the normal way by turning the key in the driver's door lock.
However, please note that when you unlock the vehicle with the key,
this only unlocks the mechanical lock on the doors set in the menu
display ⇒page 24. In order to switch off the anti-theft alarm, you
must insert the key in the ignition lock and switch on the ignition
within 15 seconds after opening the driver's door. The alarm will be
set off if the ignition is not switched on within 15 seconds.
When you lock the vehicle, this automatically locks both of the doors
and activates the anti-theft alarm.
Windows
The windows can be opened or closed together via the central
locking system ⇒page 43.
Deadlock mechanism
The central locking system is combined with a deadlock mecha-
nism. Once the vehicle has been locked from the outside, the door
handles on the inside are deactivated. This makes it more difficult
to break into the vehicle.
However, it is also possible to lock the vehicle without activating the
deadlock mechanism.

lighting* will be switched off when the car automatically locks again
⇒page 41.
Note
•
If you always wish to use the coming home / leaving home func-
tion, you can leave it switched on permanently. As the system is
controlled via a light sensor, it will only work in dark conditions.
•
Permanent use of the coming home / leaving home function, in
particular on short journeys, will increase the load on the battery. To
make sure the battery is always sufficiently charged, occasionally
drive longer distances.
•

Driving 82Starting the engine
Turn the key to this position to start the engine. While the engine is
being started the headlights are switched back to side lights and
other major electrical equipment is switched off. After the engine
has started the ignition key returns to position by itself.
The ignition key has to be turned back to position before re-
starting the engine. The starter inhibitor in the ignition lock
prevents the starter motor from engaging when the engine is
running, as this could cause damage.
WARNING
•
Wait for the vehicle to come to a standstill before removing the
ignition key from the lock. Otherwise the steering lock could
engage suddenly, which could cause an accident.
•
Always take the key with you when leaving the vehicle – even
if you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine or use power-operated equipment such as
the electric windows - this could lead to injuries.Note
If the battery has been disconnected and then reconnected it will be
necessary to leave the key in position for about 5 seconds before
starting the engine.Starting the engineThe engine can only be started with an original Audi key.On vehicles with R tronic, the engine can be started in
neutral (N) or in any gear (1 - 6 or R).
– Apply the handbrake firmly ⇒.– Push the clutch pedal all the way down (vehicles with
manual gearbox).
– Press and hold the brake pedal.
– Turn the ignition key to position ⇒page 81, fig. 72
without pressing the accelerator.
– Release the ignition key as soon as the engine starts; the
starter motor must not be allowed to run on with the
engine. Neutral gear (N) will be engaged on vehicles with
Rtronic.
When starting from cold the engine may be a little noisy for the first
few seconds until oil pressure has built up in the hydraulic tappets.
This is quite normal, and no cause for concern.
If the engine fails to start straight-away, switch off the starter after
about 10 seconds and try again after about half a minute.
WARNING
•
Never run the engine in confined spaces. The exhaust gases are
toxic.
•
If the engine is running and a gear is engaged, you will need to
hold the car with the footbrake.Caution
Avoid high engine speeds, full throttle and extreme load conditions
until the engine has reached its normal operating temperature,
otherwise this can damage the engine.
For the sake of the environment
Do not warm up the engine when the vehicle is stationary. You
should drive off immediately whenever possible. This will help avoid
unnecessary exhaust emissions.
