9-58 Driving and Operating
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 5‑32.
Text will be displayed on the
instrument cluster notifying the
customer that a utility interruption
has occurred. See Instrument
Cluster on page 5‑9.
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. See
“Charge Level Button” in this
section. Reduced level mode allows
a non‐dedicated circuit to be used
but increases the charging time.

charged with standard vehicle
charging equipment complying to:
