It'* FW1 that indicates the adjustable suspension.
Just a side-note, here. If the "perform ride" and "touring ride" lights are both lit up on the console at the same time, this feature is NOT working properly. Not a deal breaker, as many computer command ride (CCR) systems are no longer functional on many members cars here. Big $ to repair the CCR, but aftermarket struts to provide the leveling function are available for a reasonable price. You just won't have the ability to select the firmness for the front and rear struts anymore.
