Transportation Mode

When transportation mode is active, the air suspension ride height selection switches are disabled. Periodic re- leveling is also disabled.

When the vehicle is started, the Chassis Control Module (CHCM) will cause the vehicle to rise allowing sufficient ground clearance for the vehicle to be loaded. While the height is changing, the air suspension control status indicator will flash and a chime will be emitted by the Instrument Cluster (IC). When the correct height is reached, all the indicators will illuminate continuously and the chime will stop.

When the engine is switched off, the CHCM will cause the vehicle to lower allowing the vehicle to be strapped down. While the height is changing, the air suspension control status indicator will flash. When the low height is reached, the status indicators will illuminate continuously.
