That'* right, the feature is referred to as Parade Dimming in the owners manual. If you select park lamps or headlamps during daylight hours, the instrument panel back lighting will illumunate full brightness. The capability for dimming the IP does not exist in this mode. When day turns to night, the IP lighting will shift automaticly to a "dimmed" condition according to where you have the dimming rheostat set.
