2007 AUDI R8 sensor

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.

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.
