need help check engine code PO442

hello!,
I have a 1998 golf gl, 5speed, check engine code PO442:"EVAP Emission Control System Leak (small)". The car runs fine, with no problems, however I would like to know what this means, how to fix it and if is not "wise" to drive the car. the car has 122k. also, according to the miles - do I need to replace timming belt?.
thanks for the help.!!

The gas tank system is sealed so vapor cannot get out, there is a leak in the EVAP sysem that keeps it sealed. Check all the little vacuum hoses around the engine, they commonly crack & fray. The belt should have been changed at least once by now.

thanks for the info..., now, is it dangerous to drive like this, could this cause fire?,

Highly improbable unless you are smelling raw gas.

thanks.
