Blinking front wheels: means that the 4wd is not completely disengaging. Usually a vacuum or solenoid problem (do a search here, na-discuss na ito). In the meantime, just put in in 4H so it won't tire itself trying to disengage. In this mode, you have a 4wd system similar to the new Suzuki Vitara, most Land Rovers, RAV4, etc.

The rear wheel icons never blink, they only turn off when you put the transfer gear lever into NEUTRAL

The center orange square is the center diff lock. Used for off-road conditons only. Engaged by shifting into 4Hlc and 4Llc.
