If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure that it
has been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0288. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Fuel0286.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0295.
See your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.

Door Ajar Light
For vehicles equipped with this light,
it comes on when a door is open or
not securely latched. Before driving,
check that all doors are properly
closed.

To view the Power Flow screens in the
infotainment display, touch
Uon the
Home page or on the Application Tray
on the top of the infotainment display.
Then touch FLOW at the bottom of
the display.
The Power Flow screens indicate the
current system operating condition.
The screens show the energy flow
between the engine, generator, and
high voltage battery. These
components will be highlighted when
they are active.
Programmable Charging
(PLUG-IN Only)
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 you plug in to 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 12 amp
continuous load.
. Electrical outlets may wear out
with normal usage or 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.

154 INSTRUMENTS AND CONTROLS
Delay (Electric Rate and Departure
Time) :The vehicle estimates the
charging start time based on the
utility rate schedule, utility rate
preference, and the 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.
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.
Charge Limit Selection
The Charge Limit Preference setting
allows the customer to select their
vehicle’s charge level so it matches the
capability of their charging location.
If the vehicle consistently stops
charging after plugging in, or if a
circuit breaker continues to trip,
reducing to a lower Charge Limit
Preference may resolve the issue.
The Charge Limit Preference should be
configured to match the electrical
current rating for the electrical outlet
that the charge cord is connected to.
The Charge Limit Preference
settings are: .
Maximum: Limits AC current to
12 amps
. Reduced: Limits AC current to
8 amps
Exact current levels may vary from
the values shown in this manual.
Check the vehicle for the current
available levels.
The Charge Limit Preference setting
can be changed at any time while the
infotainment display is operable.
For some vehicles, the Charge Limit
Preference must be updated prior to
the vehicle being charged and the
Charge Limit Preference will reset to a
default value when the vehicle is
shifted from P (Park).
{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 (Continued)

is a planned departure prior to the
scheduled departure time. Use the
Latest setting to optimize energy
usage.
Charge Rate Preference Selection
From the Charge Rate Information
screen, touch Charge Rate Preference.
Touch one of the following options to
select the Charge Rate Preference:
.Charge during Peak, Mid-Peak, and
Off-Peak Rates: The vehicle can
charge during any rate period to
satisfy the next planned departure
time. However, it will select when
to charge to minimize the total
cost of the charge.
. Charge during Mid-Peak and
Off-Peak Rates: The vehicle will
charge during Off-Peak and/or Mid-Peak rate periods only and
will select when to charge to
minimize the total cost of the
charge.
. Charge during Off-Peak Rates: The
vehicle will only charge during
Off-Peak rate periods.
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 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. Electric Rate Plan Selection
Electric rates, or cost per unit, may
vary 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 called Off-Peak
rates. In some areas, a Mid-Peak rate
is offered.
Contact the utility company to obtain
the rate schedule for your area. The
summer and winter start dates must
be established to use a summer/winter
schedule.
From the Charge Rate Information
screen, touch Electric Rate Schedule.
