The mobile internet site, built and hosted by Kilrush, the newly formed division at Mobile Interactive Group, features exclusive content including a David Caruso ringtone, a selection of wallpapers, video previews and a gallery of images.
Every week the site will be updated with a synopsis of the coming week's episode.
The mobile internet site will be marketed on Five's website and on the channel itself. Text messages will also be sent to all of Five's opt-in database entries.
Tessa Cannon, marketing campaign manager at Five, said: "This is the first time we've opted to integrate a mobile site to promote the launch of a new series of any Five programme.
"CSI Miami has a broad viewing base and we wanted to provide a more integrated approach to promoting programmes on Five.
"The Kilrush team worked closely with marketing and the digital, technical and creative teams to deliver a great site and we're planning to integrate more mobile internet activity for other Five programmes throughout the coming year."
The latest series of 'CSI Miami' premieres tonight June 30 at 9pm on Five.
Matt Cockett, commercial director at Kilrush, said: "It's great to see Five continuing to invest in mobile as we really believe it's a core component to a successful digital communications strategy.
"Our consultative approach has enabled us to build a good relationship with multiple teams at Five and we look forward to working with them to expand their mobile proposition."
