How do I put my LG Flick on Vibrate?

[YourGreatestNightmare]

I have just bought my LG Flick yesterday. I am still trying to figure out how to set all of my settings to Vibrate mode (we aren't allowed to have phones ringing in our classes at school). I have also checked on google but nowhere explains how to change the setting into Vibrate mode, and neither does the LG website. I would really appreciate the help

When on the home screen press and hold the volume down button until the phone enters 'silent mode'.
