Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a

activated the indicator lamp in the “SOS” button stays
on after turning electronic key in starter switch to
position 2.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
