the following priority.

Automatic emergency – First priority

Manual emergency – Second priority

Roadside assistance – Third priority

Should a higher priority call be initiated 
while you are connected, an upgrade (al-
ternating) tone will be heard and the ap-
propriate indicator lamp will flash. If

fication number or customer information is

sion is completed. Once a call is conclud-
