Seat systems
A variety of sport seats are available for the Audi TT. In the
basic trim, the sport seat has sporty side bolsters and is
manually adjustable for length.
The optional Multicontour S sport seat (TTS model only)
has an integrated head restraint and an electrical lumbar
support.
This seat is available with pneumatically adjustable back-
rest side bolsters and a pneumatic lumbar support.
The multi-contour seat control unit controls the following
functions:
• When entering and leaving the vehicle, the bolster
cushions are lled with air or vented in order to ensure a
more comfortable entry and exit.
• All cushions are vented a short time after switching o
the ignition.
• The selected settings for inating the backrest side
bolsters and the lumbar support in the driver's seat are
saved to the vehicle key.
For the backrest side bolsters, one valve is used per cushion
to prevent pressure equalization when cornering.
