Technical data Switching off the ESP and traction control system
(ASR)
To switch off the ASR and ESP in certain situations (e.g. when
driving with snow chains, in deep snow, or on a loose surface, or
when rocking the car backwards and forwards to free it from mud)
press the button for longer than 3 seconds. The ESP warning
lamp will light up and the message ESP switched off will appear in
the driver information system display. You should only use this
feature if your driving ability and traffic conditions allow you to do
so safely.
Switching on the ESP/traction control system (ASR)
To activate the ASR/ESP, press the button again.
Overheating of the brakes
To prevent the disc brake of a braked wheel from overheating, the
EDL cuts out automatically on the wheel in question if subjected to
excessive loads. The car remains operational and will behave in the
same way as a car without EDL.
The EDL will switch on again automatically when the brake has
cooled down.
WARNING
•
The grip provided by the ESP, ABS, EDL and ASR systems is still
subject to the physical limits of adhesion. Always bear this in
mind, especially on wet or slippery roads. If you notice the
systems cutting in, you should reduce your speed immediately to
suit the road and traffic conditions. Do not let the extra safety
features tempt you into taking any risks when driving – this can
cause accidents.
•
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow too close behind the vehicle in front of you. Please bear in
mind that even ESP, ABS, EDL and ASR cannot compensate for the
increased accident risk.
•
When accelerating on a uniformly slippery surface (for instance
all four wheels on ice or snow), press the accelerator gradually and
carefully. The driven wheels may otherwise start to spin (in spite
of the EDL), which would impair the car's stability and could lead
to an accident.
•
Please note that, when the traction control system (ASR) or
ASR/ESP is switched off, the driven wheels may start to spin,
causing the vehicle to lose grip, in particular on slippery or wet
roads - danger of skidding!Note
•
In the event of a malfunction in the rear spoiler system or in the
Audi magnetic ride, it may not be possible to switch off the traction
control system (ASR) or ASR/ESP, or the ASR/ESP may be reactivated
automatically from the deactivated status.
•
If a malfunction should occur in the EDL, this is indicated by a
warning lamp ⇒page 19.
•
Some racing circuits (e.g. with banked curves) can affect the
behaviour of the ESP.

Intelligent technology 136front wheels is not obstructed, otherwise the brakes can overheat. Power steeringThe power steering assists the driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed
to turn the steering wheel.
The power steering does not function when the engine is switched
off. In this case the steering wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary,
this will place an excessive load on the power steering system. In
this case, the power steering system will make noises. It will also
reduce the idling speed of the engine.
Caution
Do not keep the steering in the full-lock position for longer than
15 seconds when the engine is running – this could cause damage
to the power steering system.
Note
•
If the power steering should fail at any time or the engine is
switched off (for instance when being towed), the car can still be
steered. However, more effort will be required to turn the steering
wheel.
•
If the system is leaking or malfunctioning, please take the car to
a qualified workshop as soon as possible.
•
The power steering requires a special hydraulic fluid. The
container for the fluid is located in the engine compartment. The
correct fluid level in the reservoir is important for the power
steering to function properly. The hydraulic fluid level is checked at
the Inspection Service.
Four-wheel drive (quattro®)On quattro models the engine power is distributed to all
four wheelsGeneral notes
On four-wheel drive vehicles, the engine power is distributed to all
four wheels. The distribution of power is controlled automatically
according to your driving style and the road conditions. Also refer
to ⇒page 132.
Winter tyres
Thanks to its four-wheel drive, your car will have plenty of traction
in winter conditions, even with the standard tyres. Nevertheless, we
still recommend that winter tyres should be fitted on all four wheels
when winter road conditions are expected, mainly because this will
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars
with four-wheel drive ⇒page 171, “Snow chains”.
Replacing tyres
The dimensions of the wheels and tyres used on four-wheel drive
vehicles must comply with the manufacturer's specifications
⇒page 168, “Replacing wheels and tyres”.
WARNING
•
Even with four-wheel drive, you should always adjust your
speed to suit the conditions. Do not let the extra safety provided
tempt you into taking any risks when driving – this can cause acci-
dents.
•
The braking ability of your car is limited by the grip of the tyres.
In this respect, your car is no different from a car without four-
wheel drive. So do not be tempted to drive too fast on icy or slip-

Technical data The performance of winter tyres is also severely impaired by ageing,
even if the tread is still much deeper than 4 mm.
Winter tyres are subject to the following maximum speed limits
according to speed rating code letter: ⇒
In Germany vehicles capable of exceeding these speeds must have
an appropriate sticker attached so it is visible to the driver. Suitable
stickers are available from Audi R8 dealers and specialist retailers.
Please note regulations to this effect in your country.
Using winter tyres with V-rating
Please note that the generally applicable 240 km/h speed rating for
winter tyres with the letter "V" is subject to technical restrictions;
the maximum permissible speed for your vehicle may be signifi-
cantly lower. The maximum speed limit for tyres with a V-rating
depends directly on the maximum axle weights for your car and on
the listed weight rating of the tyres being used.
It is best to contact an Audi R8 dealer to check the maximum speed
which is permissible for the V-rated tyres fitted on your car on the
basis of this information.
WARNING
Exceeding the maximum speed permitted for the winter tyres
fitted on your car can cause tyre failure, resulting in a loss of
control of the vehicle – risk of accident.
For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give
better handling on roads which are free of snow and ice. Summer
tyres produce less rolling noise, do not wear down as quickly and,
most importantly, reduce fuel consumption.Snow chains
Snow chains will improve the vehicle's handling on snow-
covered roads.– Snow chains can be used on the rear wheels only.
– Keep your speed below 50 km/h.Snow chains will improve braking ability as well as traction in winter
conditions.
For technical reasons snow chains may only be used on tyres with
certain wheel rim/tyre combinations.
Only use snow chains with fine-pitch links. The links must not
protrude more than 13,5 mm from the tyres (including tensioner).

Wheels and tyres 172Remove wheel covers (if fitted) and trim rings before attaching
snow chains. For safety reasons cover caps must then be fitted over
the wheel bolts. These are available from Audi R8 dealers.
Remove the chains when roads are free of snow. Otherwise they will
impair handling, damage the tyres and wear out very quickly.
Four-wheel drive: Where snow chains are compulsory on certain
roads, this normally also applies to cars with four-wheel drive. Snow
chains may only be fitted to the rear wheels (also on vehicles with
four-wheel drive).Tyre pressure monitoring systemApplies to vehicles: with tyre pressure monitoring systemIntroduction
The tyre pressure monitoring system keeps a check on the
inflation pressures of the four road wheels while you are
driving.The system warns the driver in the event of a loss of pressure by
means of symbols and messages in the instrument cluster display.
The system employs sensors on the wheels. The radio signals from
these sensors are transmitted to the tyre pressure monitoring
system.
Please bear in mind that the tyre inflation pressure is also influ-
enced by the temperature of the tyre. For every 10°C increase in the
tyre temperature the pressure will normally increase by about
0.1 bar. The tyre heats up while the vehicle is being driven and the
tyre pressure will rise accordingly. For this reason, you should only
adjust the tyre pressures when they are cold (i.e. approximately at
ambient temperature).
To ensure that the tyre pressure monitoring system works reliably,
you should check and, if necessary, adjust the tyre pressures at
regular intervals.The tyre pressures recommended for your vehicle are given on the
sticker attached to the driver's door pillar.
Initialising the tyre pressure monitoring system
The inflation pressures for two sets of wheels (e.g. with winter and
summer tyres) are stored on your vehicle. You can change between
these two sets of wheels any number of times without re-initialising
the system.
The tyre pressure monitoring system must be re-initialised by your
Audi R8 dealer if a new set of wheels is used or the electronic
sensors are renewed.
Warning lamp
 lit
If the tyre pressure is more than 0.5 bar below the reference value,
the display will show the tyre symbol
 with a corresponding
message, such as Tyre pressures too low ⇒.
WARNING
•
If the warning lamp
 lights up you must slow down immedi-
ately and avoid any severe braking or steering manoeuvres. As
soon as you can do so safely, stop and check the tyres and the tyre
pressures.
•
Never re-adjust the tyre inflation pressure when the tyre is hot.
This can cause serious damage to the tyre or even a blow-out,
which could result in an accident.
•
Under-inflated tyres flex more and can overheat at continuous
high speeds. This can cause tread separation and tyre blow-out,
which could result in an accident.For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre
wear.

Technical data
Note
•
Responsibility for ensuring that the tyres are correctly inflated
remains with the driver; the system can only provide assistance.
•
Only adjust the inflation pressure of the tyres when they are at
approximately ambient temperature.
•
The sensors and valves do not have to be detached or changed
round when fitting new tyres. Only the valve core needs to be
replaced, and if necessary the valve and the electronic components
in the wheel.
•
After using the Tyre Mobility System* the tyre pressure moni-
toring system may malfunction. The sensor for the tyre pressure
monitoring system must therefore be renewed by a qualified
workshop.
Applies to vehicles: with tyre pressure monitoring systemMalfunctionsIf the tyre pressure monitoring system is inoperative, the tyre
symbol or “TPMS” will appear on the display. This can have various
causes:•
One of the wheel sensors or other related components may not
be working.
•
Snow chains can interfere with the signals emitted by the
sensors so that the system cannot function properly.
•
The tyre pressure monitoring system may be inoperative due to
radio interference.
•
Radio systems operating on the same frequency, such as radio
headphones or two-way radios inside the vehicle, produce strong
electromagnetic fields which can cause temporary interference.
•
If the fault persists, take the vehicle to a qualified workshop.
