I suppose the fuel gauge reserve warning light break down very rarely. But it could happen..
According to the manual, the fuel gauge and the warning light are both operated by the central instruments module. So if the gauge is really OK, then the problem is the light itself.
Procedure is simple, but maybe you noticed the interior looks nice but not sturdy. I'm not familiar with your pre-facelift interior but you probably have to remove the radio. Just make sure you don't break something else just to fix a silly light; although I always do that...
PS: If you bought from a car lot and if the payout is high, I'd bet a removed the light bulb before selling it, because it was flashing. Then you would have another problem. But I don't wish you that of course... I hate car salesmen.
