If the word OFF or the off symbol is lit on
the passenger airbag status indicator, it
means that the passenger sensing system
has turned off the front outboard passenger
frontal airbag and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there are no
lights at all, there may be a problem with
the lights or the passenger sensing system.
See your dealer for service.
{Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself

Programmable Charging
Important Information about Portable Electric
Vehicle Charging
.Charging an electric vehicle can stress a
building’s electrical system more than a
typical household appliance.
.Before plugging into any electrical outlet,
have a qualified electrician inspect and
verify the electrical system (electrical
outlet, wiring, junctions, and protection
devices) for heavy-duty service at a
10 amp continuous load.
.Electrical outlets may wear out with
normal usage or may be damaged over
time, making them unsuitable for electric
vehicle charging.
.Check the electrical outlet/plug while
charging and discontinue use if the
electrical outlet/plug is hot, then have the
electrical outlet serviced by a qualified
electrician.
.When outdoors, plug into an electrical
outlet that is weatherproof while in use.
.Mount the charge cord to reduce strain
on the electrical outlet/plug.
.Do not place the charge cord in a position
where it is expected to be submerged in
water.
{Danger
Improper use of portable electric vehicle
charge cords may cause a fire, electrical
shock, or burns, and may result in
damage to property, serious injury,
or death.
.Do not use extension cords,
multi-outlet power strips, splitters,
grounding adaptors, surge protectors,
or similar devices.
.Do not use an electrical outlet that is
worn or damaged, or will not hold the
plug firmly in place.
.Do not use an electrical outlet that is
not properly grounded.
.Do not use an electrical outlet that is
on a circuit with other electrical loads.
See Plug-In Charging 0181.
Programmable Charging Modes
To view the current charge mode status in
the infotainment display, touch Energy and
then touch Charging.
The charge Start and Complete time
estimates are also displayed. These
estimates are most accurate when the

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
14637856) - 2021 - CRC - 10/2/20
92 Instruments and Controls
The Portable Cord Limit setting should be
configured to match the electrical current
rating for the electrical outlet that the
charge cord is connected to. On the Charge
Mode tab, toggle the Portable Cord Limit
selection between:
.12 amps
.8 amps
Exact current levels may vary from the
values shown in this manual. Check the
vehicle for the current available levels. When
the vehicle is plugged into a charging
station, the Portable Cord Limit option on
the Charge Mode tab will not be available.
The Portable Cord Limit can be changed and
saved using Location Based Charging
settings. The default value is the lower
Portable Cord Limit. The Portable Cord Limit
will reset to the lower value when the
vehicle is shifted from P (Park) unless the
Location Based Charging feature is active
and set to retain this preference. See
“Location Based Charging” later in this
section.
{Warning
Using a charge level that exceeds the
electrical circuit or electrical outlet
capacity may start a fire or damage the
electrical circuit. Use the lowest charge
level until a qualified electrician inspects
the electrical circuit capacity. Use the
lowest charge level if the electrical circuit
or electrical outlet capacity is not known.
Electric Rate Preference
The vehicle estimates the charging start
time based on the utility rate schedule,
utility rate preference, and programmed
departure time for the current day of the
week. The vehicle will charge during the
least expensive rate periods to achieve a full
battery charge by the departure time.
Electrical rate information from the utility
company for the charging location is
required for this mode. If the selected
charge mode is Departure, then electric rate
preference selection will display. Electric Rate Preference Selection
From the Charge Mode tab on the Charging
screen with Departure charge mode selected,
touch More to select the Electric Rate
Preference.
Touch one of the following options to select
the Electric Rate Preference:
.Off: Delay charging based on departure.
.Off-Peak Only: Charge during Off-Peak
Rates.
.Cost Optimized Off- and Mid-Peak: Charge
during Mid-Peak and Off-Peak Rates.
.Cost Optimized All Rates: Charge during
Peak, Mid-Peak, and Off-Peak Rates.
Charging begins at the start time and is
complete by the departure time only if
sufficient time is allowed after the charge
cord is plugged in. For example, if the
vehicle is plugged in for only one hour prior

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
14637856) - 2021 - CRC - 10/2/20
Instruments and Controls 93
to the departure time, and the battery is
completely discharged, the vehicle will not
be fully charged by the departure time
regardless of the rate selection.
Also, if the selected electric rate settings
result in a very long charge completion
time, the vehicle will start charging
immediately upon plug-in. For example,
if the electric rate table is set up with all
Peak rates and the rate preference is to
charge during Off-Peak rates only, then the
vehicle will start charging immediately upon
plug-in.

based on time, weekday/weekend, and
season. During the day when the demand
for electricity is high, the rates are usually
higher and called Peak rates. At night when
the demand for electricity is low, the rates
are usually lower and are called Off-Peak
rates. In some areas, a Mid-Peak rate is
offered.
