Utility Interruption of Charging (PLUG-IN Only)

If using AC charging, this vehicle will respond to remote requests through OnStar to limit or completely block

electrical power grid usage for brief

time periods. A utility interruption of charging may increase AC vehicle

charge times.

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 the vehicle can automatically begin


Changing the charge mode to

Immediate or performing a delayed charging override will not disable a utility interruption.

A pop-up will appear in the

infotainment display during the key cycle following any utility

interruption. See Charging

Interrupted or Overridden Pop-Up

under Programmable Charging (PLUG-IN Only) 0 150.

A message will display on the

instrument cluster indicating that a utility interruption has occurred.

See Instrument Cluster (Base Level)

0 127 or Instrument Cluster (Uplevel)

0 130.

Charging Station Troubleshooting

If the vehicle does not charge after being plugged in to a residential

240-volt charging station:

1. Verify that the charge mode is set to Immediate.

2. Verify that the charging stations circuit breaker has not been


3. Plug the portable charge cord

into the wall outlet, verify that

the indicator light on the charge

cord is solid green, and connect it to the vehicle. See Charge

4. If the vehicle charges with the

portable charge cord, there may be a problem with the charging

station. Try to charge the vehicle

with a different 240-volt charging station, such as a public station.

If both attempts charge the

vehicle, contact the charging station manufacturer.
