Hi,
Ok, so just to clarify my earlier post - there is no SIM required for an
'Emergency SOS' call. That is handled by the Services Module.
A SIM card is required by the owner to use the Citroen 'Services' button for breakdown etc. I would recommend you get a 2G, but if cannot get one of these, use as basic SIM as possible without any bells and whistles. I have used a Vodafone SIM and they are fine.
The Service Module's function is to act as a:
- Telephone
- Emergency call
- Network service call
This function is used to reduce the time taken by the assistance services to reach the vehicle in the event of a problem or an accident.
The vehicle communicates its geographical position and other information to a service provider which serves as an interface for alerting the breakdown assistance and/or emergency services.
The emergency call is made in one of the following ways:
Manually using with the "SOS" button (Press for more than 2 seconds)
Automatically when the airbags are triggered
The NG4 Navidrive 3D system works in conjunction with the Services Module. You can switch between using the internal phone or your bluetooth phone (if you have one). The emergency system uses the internal phone only and can switch automatically in an emergency back to the internal phone.
| Element | Action on the Button | Designation |
| "n" | One press of more than 2 seconds | Assistance call (A voice message confirms that the call has been made) |
| One press | Cancel the call (A voice message confirms cancellation) |
| "p" | One press of more than 2 seconds | Emergency call (The flashing of the green diode plus a voice message confirm that the call has been made)) |
| 1 Guide | Cancel the call (confirmed by the green diode going off) |
Normally the little orange light on the SOS button only illuminates during startup (as it awaits information from the Services Module regarding the Airbag Triggering Status). Try fitting an active SIM (engine off first) and then see if that solves it.
