How do I get vibrate on this phone?

Excuse me, could you please help me with something? I'm trying to figure out how to enable the vibrate mode on this phone. I've been looking around the settings, but I can't seem to find the right option. Could you guide me through the process? I'd really appreciate it if you could point me in the right direction. I'm sure it's something simple, but I'm just not familiar with the interface yet. Thank you so much for your help!
