- with CODE (349) E Call emergency call system
- with CODE (498) Japanese version


For normal telephone calls, the call is handled via the CTEL antenna (A2/22).

In the event of an accident (e. g. rollover) this antenna can be destroyed. This means that an emergency call would no longer be possible In order to avoid this situation without fail, the emergency-call backup antennae (A2/50) have also been installed along with the CTEL antenna.

These are mounted in largely crash resistant conditions in the vents below the rear bumper and are only used where necessary. As long as an alarm call is not actuated, the CTEL antenna is always active. In the event of an emergency call, the E-call control module
(A35/8) checks the signal level of the telephone antenna and the Emergency-Call backup antenna (A2/50).
Depending on the result the E-CALL control module (A35/8) then switches over to the "better" antenna and transmits the emergency call.
