Tele Aid system may not function and if this
occurs, assistance must be summoned by other
means.

ing the system self-check, or if any of these
indicators remain illuminated continuously
in red and/or the message

Inoperative
is displayed in the multifunc-
tion display after the system self-check,
a malfunction in the system has been
detected.
If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
