In a 1985 Buick Park Avenue (and other cars of that era with similar systems), the "car is leveling" message in the information center refers to the
automatic leveling system for the headlights. This system adjusts the headlight aim based on the car's load (passengers, cargo) to keep the beam height consistent and prevent blinding oncoming drivers.
The message indicates that the system is actively adjusting the headlights. It's usually a temporary message that disappears once the leveling process is complete.
