The cluster with the 20 digit alphanumeric display...is the HIGH cluster. :) All the check control warnings appear in the 20 digit display...and the OBC can be programmed to appear in the cluster. The main display for the "extended" OBC is either the MID or the Nav screen. The BC button on the tip of the turn signal stalk scrolls thru what has been programmed to appear in the cluster's display...and the BC button on the MID calls up the OBC on that display and allows you to set/reset/start/stop/adjust the OBC features.

The low cluster has the graphic display...and it is what gives the check control warnings along with the warning lights in the cluster. The OBC is limited (only has 4 features) and is called up by pressing the BC button on the tip of the turn indicator stalk.
