The Tele Aid system is operational providing
that

the vehicle’s battery is charged, properly
connected, not damaged, and cellular and
GPS coverage is available. The Tele Aid
system utilizes the cellular network for
communication and the GPS ( Global
Positioning System) satellites for vehicle
location. If either of these signals are
unavailable, the Tele Aid system may not
function and if this occurs, assistance must
be summoned by other means.
i A Tele Aid call cannot be canceled. Even
if the Tele Aid system is not activated or
operational, the system will attempt to
connect the respective call. This may take
as

long as five minutes or more. As long as
the Tele Aid system attempts to connect a
call, you cannot operate the COMAND
system. Also, most functions in the control
system, such as the telephone function, are
suspended. Therefore, it is not advisable to
initiate any Tele Aid call unless the Tele Aid
system is activated and operational. To adjust the speaker volume during a Tele
