Gmap script in head

If anyone knows,
Where does the following code get outputted from.
<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2.115&key=ABQIAAAAHvKgebOjQJ9b5l-T4hutPBQUG5OfJQutT8I4Xx7Ptp36hfi10hQ87h67vgnKEw6JzmmfWqkCjEHljA&hl=en">
My goal is to change the hl=en so that the names of streets, etc. are rendered in the local language rather than english and the local language.

Found this in Google API http://code.google.com/intl/el-GR/apis/maps/documentation/#Localization, but again not sure where to change the 'hl' value to something else.
