I will assume the engine code says evap. system leak detected small. One possibility is the gas cap but, any hose or vacuum line break or component issue that has a leak can could throw this code. It is an emission recovery leak and the best way to find it is with a "smoke test". Inform the dealer you need this test performed to solve the issue.
