The triangle light with the exclamation point in it came on

Hello, That is the master warning light, and it means there is likely a message for you in the instrument cluster. This light can come on with a flat tire, or engine failure, but most commonly it is because a service has been passed. Have it inspected, and have the codes read. Also, scroll through your menus, and see if you have any messages. Lastly, look at your "next service due", if your service interval is up, head on in for your service. http://repairpal.com/mercedes-benz-within-10-miles-of-bernalillo-new-mexico-87004
