Service Electric Parking
Brake Light
On some vehicles the service electric
parking brake light should come on
briefly when the vehicle is started.
If it does not come on, have it fixed so
it will be ready to warn if there is a
problem. For vehicles with the
reconfigurable cluster, this light may
not come on when the vehicle is
started.
If this light stays on, the vehicle
should be taken to a dealer as soon as
possible. SeeElectric Parking Brake
0 235. A message may also display in
the Driver Information Center (DIC).
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the system.
If the ABS light stays on, or comes on
again while driving, the vehicle needs
service. A chime may also sound when
the light comes on steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but the
antilock brakes are not functioning.
If both the ABS and the brake system
warning light are on, the vehicle's
antilock brakes are not functioning and there is a problem with the
regular brakes. See your dealer for
service.

the engine properly. The vehicle could
be low on oil and might have some
other system problem. See your dealer.

This light is near the fuel gauge and
comes on briefly when the ignition is
turned on as a check to show it is
working. For vehicles with a
reconfigurable cluster, this light is in
the display area and may not come on
when the ignition is turned on.

.Mount the charging cord to reduce
strain on the electrical outlet/plug.
{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 the charge cord user guide.
Programmable Charge Modes
This vehicle has three programmable
charge modes. To view the current
charge mode status in the
infotainment display, touch
[in
the infotainment display and then
touch CHARGING at the bottom of
the display.
The Charge Start and Charge
Complete time estimates are also
displayed on the screen. These
estimates are most accurate when the
vehicle is plugged in and in moderate
temperature conditions. Also, to get
an accurate time estimate, the vehicle
uses an internal clock for
programmable charging, not the clock
in the infotainment display.
Charge Mode Status
Immediately : The vehicle starts
charging as soon as it is connected to
an electrical outlet. See Plug-In
Charging (PLUG-IN Only) 0274.
Delay Charge Based on Departure
Time : The vehicle estimates the
charging start time considering the
programmed departure time for the
current day of the week. 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.

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)
