Preconditioning

The vehicle must be plugged into a charger to activate preconditioning. Preconditioning activates the vehicle's thermal management system to heat or cool the high-voltage batteries, eDrive, and eAxles to bring them to operating temperature by the scheduled departure time. This can reduce the initial on-road power draw from the vehicle's batteries during very hot or cold weather, increasing the predicted range on that charge.

If cab climate control is activated when scheduling a departure time, preconditioning activates the HVAC system to bring the cab to the desired temperature by the scheduled departure time.

If the scheduled departure time passes and the vehicle remains connected to the charger, preconditioning keeps the batteries, eDrive, eAxles, and cab at the desired temperature for a set amount of time.

Preconditioning deactivates if the charging cable is unplugged, the key switch is activated, or an HVAC setting is manually changed.
