There is no way to zoom lens other than with the lens zoom ring.
The +/- buttons you are refering to are used to increase/decrease the size of an image in playback mode. The +/- buttons are in blue, as is the playback arrow.

Also note that when you change the lens focal length (zoom) you will need to refocus -- because for the vast majority of DSLR lenses, the focus changes as you "zoom".
