Immediately in the event of an accident that immobilises your vehicle.

If your vehicle is driveable it is acceptable to wait until you return to the UK so long as that is not more than two weeks ahead.

NB. In the case of emergency you should contact your insurer's local representative. His name and address should have been provided to you when you advised your insurer of your intention to go abroad. If you do not have the details or the representative cannot be contacted, you should phone your insurers in the UK.
