using the Charge Limit Preference
screen on the center stack. See
“Charge Limit Selection” under
Programmable Charging 0119.
{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.
Fueling
The fuel system on this vehicle
requires a refueling process to
control evaporative emissions. To
refuel the vehicle:
1. Press the fuel door button on
the driver door for one second.
A WAIT TO REFUEL message
displays on the Driver
Information Center.
2. When the READY TO REFUELmessage displays, the fuel
door on the passenger side will
unlock. To open the fuel door,
push and release the rearward
center edge of the door.
3. Turn the fuel cap counterclockwise to remove.
While refueling, hang the fuel
cap tether from the hook on the

Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored in

In Brief 27
Less energy is used at low fan
speeds. When using the fan:
.Fan Only is the most energy
efficient climate setting as long
as
0is not selected.
. Use eco for moderate air
conditioning and heater
operation. This is the next most
energy efficient setting as long
as
0is not selected.
. MAX provides the most comfort
but is the least energy efficient.
Use the auto heated seat feature
and the heated steering wheel
instead of climate settings. Heating
the seat and steering wheel uses
less energy than heating the vehicle
interior.
Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric range by
utilizing electricity from the electrical
outlet. Engine Assisted Heating,
if equipped, can be personalized
while plugged in. See
“Engine
Assist Heat Plugged In” under
Vehicle Personalization 0141.
In hot weather, avoid parking in
direct sunlight or use sunshades
inside the vehicle.
Turn off the front and rear window
defog/defrost when they are no
longer needed.
Avoid driving with the windows open
at highway speeds.
Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold. Maintenance
Always keep the tires properly
inflated and the vehicle properly
aligned.
The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
If fuel is not regularly used, consider
keeping the fuel tank only one-third
full. Excess fuel weight impacts
efficiency and range.
For fuel recommendations, see
Fuel
0230.
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling the
vehicle will reduce EV range.
Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.

Instruments and Controls 105
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last reset.
The trip odometer is accessed and
reset through the Driver Information
Center (DIC). SeeDriver
Information Center (DIC) 0130.
Battery Gauge (High
Voltage)
This gauge shows the high voltage
battery charge level.
The arrow next to the battery
symbol points to the side of the
vehicle the charge port is on.
See Electric Mode 0180.
Fuel Gauge
When the ignition is on, the fuel
gauge indicates about how much
fuel is left in the tank.
There is an arrow near the fuel
gauge pointing to the side of the
vehicle the fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle
should be refueled soon.

106 Instruments and Controls
Here are some things that owners
ask about. None of these show a
problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.Driver Efficiency Gauge
This gauge appears on the left side
of the display in the Classic
Enhanced configuration.
This gauge is a guide to driving in
an efficient manner by keeping the
ball green and in the center of the
gauge. See
Driving for Better Energy
Efficiency 026.
accel : If the ball turns yellow and
travels above the center of the
gauge, acceleration is too
aggressive to optimize efficiency.
brake : If the ball turns yellow and
travels below the center of the
gauge, braking is too aggressive to
optimize efficiency.
In the Modern display
configurations, the light ring in the
center of the display acts as an
efficiency gauge. It is green when
driving efficiently and turns yellow
when acceleration or braking is too
aggressive.

110 Instruments and Controls
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
electric drive unit, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass
an Emissions Inspection/
Maintenance test. See
Accessories and
Modifications0237. If the light is flashing :
A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
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:
. A loose or missing fuel cap may
cause the light to come on. See
Filling the Tank 0231. A few
driving trips with the cap
properly installed may turn the
light off. .
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
Fuel 0230.
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

activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, always
keep your eyes on the road, hands
on the wheel, and mind on the drive.
. Do not use a phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
. Watch the road. Do not read,
take notes, or look up
information on phones or other
electronic devices.
. Designate a front seat
passenger to handle potential
distractions. .
Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings.
Program all trip information into
any navigation device prior to
driving.
. Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
. Stop or park the vehicle to tend
to children.
. Keep pets in an appropriate
carrier or restraint.

184 Driving and Operating
off. During EMM, a DIC message
displays to show the
EMM percentage complete.
If No is selected, the EMM Request
screen will appear when the vehicle
is next started. The EMM request
can be delayed for up to one day.
If the EMM request was delayed for
one day, EMM will automatically
start the engine at the next vehicle
start. The engine will not start until
after a short delay once shifted into
D (Drive).
An EMM Notification screen will
appear in the center stack display.
If the vehicle is shut off during EMM,
it will restart the next time the
vehicle is driven.
A message displays to indicate that
EMM is active.
If EMM is required and the fuel level
is low, EMM may eventually empty
the fuel tank if fuel is not added.
This will result in reduced, or no
power. An adequate fuel level must
be maintained in the vehicle to keep
it operational. SeePropulsion Power
Messages 0138.
Fuel Maintenance Mode (FMM)
FMM tracks average fuel age. Old
fuel can cause engine problems.
If low engine usage causes average
fuel age to exceed approximately
one year, FMM will run the engine to
use up the old fuel. The engine will
run until enough fresh fuel is added
to bring the average fuel age into an
acceptable range. Allowing more old fuel to be used up by FMM and
adding a larger amount of fresh fuel
will maximize the length of time
before another fuel maintenance
mode is needed. During FMM the
engine may turn on and off.
When FMM is needed, the FMM
Request screen appears on the
center stack display at vehicle start.
If Yes is selected, FMM will begin.
The engine will not start until after a
short delay once shifted into
D (Drive). FMM will automatically
continue at each vehicle start until
fresh fuel is added.
If No is selected, the FMM Request
screen will appear when the vehicle
is next started. The FMM request
can be delayed for only one day.
