flashing lights/keyless

I've a brand new Caravan Anniversary Edition 2004, and when I close/unclose the doors with the keyless/remote only the rear warning lights are flashing. Nothing on the front. It seems that it is not a normal behaviour... But is it a programmable feature with the RKE ??. How it can be done?
Note : I've only a Mini Trip Computer.
Sorry but such car in France is not very well known.
Thanks to everybody.
