Braking
.Classic layout: The gauge and
leaf turn yellow.
. Modern layout: When driving
inefficiently, the ball turns yellow
and moves above the center of
the gauge. When braking
aggressively, the ball turns
yellow and moves below the
center of the gauge.
. Enhanced layout: The outer ring
of the speedometer turns yellow.
Power Indicator Gauge
The power indicator gauge is on the
right side of the display in the
Enhanced layout.
This gauge displays the
instantaneous charge and discharge
power flowing either into or out of
the high voltage battery. Maximum
discharge power is available when
the high voltage battery is fully
charged. During normal operation, a
slight reduction in discharge power
may occur as the high voltage
battery state of charge decreases.
The power indicator gauge value
shows the instantaneous power
used by the battery.
Regenerative Braking
When regenerative braking is active,
the regen battery icon with arrows
appears green. The power indicator
gauge value shows the amount of
instantaneous power being
regenerated.
Regenerative Power Limited
Regenerative power may be limited
when the high voltage battery is
near full charge or cold. The regen
battery icon will appear gray when limited, and a horizontal bar may
display on the gauge, at the level of
the vehicle’
s maximum regenerative
braking power.

When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a system check. Then, after
several seconds, the status
indicator will light either ON or OFF,
or the on or off symbol to let you
know the status of the front
outboard passenger frontal airbag
and knee airbag. If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag
and knee airbag are allowed to
inflate.
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

Charging System Light
(12-Volt Battery)
The charging system light comes on
briefly when the vehicle is started,
as a check to show the light is
working.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the 12-volt battery.

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 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 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.

{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 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.
