are driving, or if it starts to flash, then there is a malfunction some ­
where in the system. If the light does not illuminate when you
switch on the ignition, this also means there is a malfunction.

If you have a malfunction in the airbag system, contact your autho­
rized Audi dealer immediately. Otherwise the airbag or the belt
tensioner may not work properly in an accident. •

indicator lamp

significant loss of air pressure.

ously illuminated. This sequence will continue upon subsequent
