Multi-Displacement System (MDS) (If Equipped) — 5.7L Engine Only

This feature offers improved fuel economy by shutting off four of the engine’s eight cylinders during light load and cruise conditions. The system is automatic with no driver inputs or additional driving skills required.

NOTE:
The MDS system may take some time to return to full functionality after a battery disconnect.
