The Aerodynamic Height Control feature on the New Cascadia is a feature that raises and lowers the air suspension with relation to vehicle speed in order to reduce drag and achieve better fuel efficiency.

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
