Driving and Operating Charge Level Selection Charge level selection can be made using the Select Charge Level Preference screen on the center stack. See "Charge Level Selection" under Charging on page 5‑30. 9-55 Utility Interruption of Charging For participating customers, this vehicle will respond to remote requests via OnStar to limit or completely block electrical power grid usage for brief time periods. A utility interruption of charging may increase vehicle charge time. When electrical grid power is completely blocked, the vehicle will delay charging until the utility interruption has expired. The vehicle should be left plugged in so that, when the utility interruption expires, the vehicle can automatically begin charging. Changing the charge mode to Immediate or performing a delayed charging override will not disable a utility interruption. A pop‐up will be displayed in the center stack display during the key cycle following any utility interruption. See "Charge Override/ Interruption Pop‐up" under Charging on page 5‑30. Text will be displayed on the instrument cluster notifying the customer that a utility interruption has occurred. See Instrument Cluster on page 5‑8. { WARNING Using a charge level that exceeds the electrical circuit or socket capacity may start a fire or damage the electrical circuit. Use the lowest charge level until a qualified electrician inspects your electrical circuit capacity. Use the lowest charge level if the electrical circuit or socket capacity is not known. Electrical Requirements for Battery Charging The AC outlet must have a grounded, dedicated, 15 amp or greater, three-prong wall plug. That means there should be no other major appliances connected to the same circuit. If it is not a dedicated circuit, the current rating of the outlet circuit breaker could be exceeded and cause it to trip or open. The vehicle can be charged in the reduced level mode. Charge level selection can be made using the Select Charge Level Preference screen on the center stack. See "Charge Level Selection" under Charging on page 5‑30.
