I believe the Mercedes ME service is free for 3 years (not 5). But you'd need to verify this with your local dealer.
Per the Mercedes website:
Connected Services are complimentary for 3 years. After the 3-year period expires, some services may need to be renewed.
You can create your Mercedes me account at any time on the Mercedes me Portal. However, in order for you to enable and use your Mercedes me connect (Mmc) services, your Vehicle Identification Number (VIN) must be paired to your account. The action of pairing can only be done by an authorized Mercedes-Benz dealership. You will need to present a valid proof of identity (Driver’s License), provide the email address used for your Mercedes me account and present a copy of your vehicle's registration. Once the pairing completed, you will need to accept the Terms of Use and activate Mmc services in your Mercedes me account. Finally, you will also need to download the Mercedes me App on the App Store in order to use connected services on your mobile device.
