H2 dashboard cluster
 

I am currently driving a 2005 h2 and just started to experience all the dash board lights coming on and bells going off while driving including the radio and sometimes the heater shutting off and on. Also door locks not working and digital read out saying to service. Just wondering for some input.

Battery probably needs replacement, especially if it is the original one.
My VW did that and the cure was the battery so stick another one in.
