additional ly the => fig. 44 symbol appears in the display, the
tire pressure monitoring system is not available . This can have
various causes.
• If the message appears at the end of the learning phase, the
system cannot recognize the wheels insta lled on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed.
• The system has detected more than 4 wheels in the vehicle, for
example while driving beneath another car with tire pressure moni ­
toring system .
• A tire was changed but
the => page 50, "Changing a wheel"
procedure was not activated
=> page 50.
• Audi replacement parts were not used .
• If snow chains are being used , system function can be compro ­
mised due to the shie lding properties of the chains .
• The tire pressure monitoring system may not be available
because of a radio malfunction .
• Transmitters with the same frequency , such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
dis ruption of the system through excessive el ectromagn etic fie lds.
• Try to find the cause of the interference, and then perform the
=> page 50, "Changing a wheel" procedure one more time . If this not
e liminate the prob lem , contact your authorized Audi dea ler for
assistance .
• Do not use commercially available tire sealants. Otherwise , the
electrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replac ed by a qualified workshop. •

Power steering
Power steering makes it easier to steer the vehicle when
the engine is running.
If the engine is not running the power steering does not work and
you will find it more difficult to turn the steering wheel.
Whenever the steering wheel is turned all the way to the left or right
a lo t of stress is placed on the power steering pu mp. When this
happens you will hear a noise coming from the power steering
pump .
0 Note
Never hold the steering wheel turned all the way to the left or right
longer than 15 seconds when the en gine is running -damage to
the power steering system is likely! •

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road
=>& .There ­
fore:
Do not let yourself be distracted by passengers or by
using a cellular telephone .
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •
