If you need to replace the remote contro l, or if
you need to have it repaired, you must see
your author ized Audi dealer. Only then can
you use the key again .

deac tivates the elec tronic immobilizer when
you insert the key in the ignition lock , or on
vehicles with Convenience key*, when the key
is ins ide the veh icle. When you remove the key
from the ignition lock, or on vehicles with
Convenience key, when you remove the key
from the vehicle, the electronic immobilizer is
automatica lly activated once again.
WARNING
Always take the key with you when you
l eave the vehicle. The key can disarm the
electronic engine immobilizer and permit
an unauthorized person to start the engine
and enable operation of the vehicle sys­
tems such as power w indow or Panoramic
slid ing sunroof* leading to serious person­
al injury.
u) Tips
-The vehicle cannot be started if an unau­
thorized key is used . The vehicle may not
start if another radio device such as a key
for another vehicle or a transponder is
located on the key ring.
