Empower instrument cluster level only: The

indicator next to the

gauge will illuminate in green or white to indicate the following:
•

Indicator white: This indicates that the hybrid system is not

warm enough to allow operation in electric vehicle mode only. The
gasoline engine will run continuously when the indicator is white.

Note: During silent key start mode, the

indicator will be white,

but the gasoline engine will not run. This is a result of the vehicle
computer allowing the engine to be cooler during the silent key start
period. This is normal operation and does not indicate a problem with
your vehicle. After the first engine start, the

indicator will turn

green when the gasoline engine is warm enough to turn off.

•

Indicator green: This indicates that the hybrid system is warm

enough to allow operation in electric vehicle mode.

If the vehicle operates in electric mode long enough, it is possible that
the gasoline engine may need to run to keep the system warm. In this
case, the

indicator will revert back to white.

High-voltage battery information
gauge: The fill level indicates the
amount of energy stored in the
high-voltage battery as a percent of
total energy capacity. The level will
increase and decrease as the battery
charges and discharges during
normal operation, but the hybrid
system will attempt to control the
level to approximately the middle of
the gauge under most driving
conditions.

Enlighten, Engage and Empower instrument cluster levels only: The
up and down arrows provide information about the energy (both stored
and used) associated with the high voltage battery. The up arrow
indicates battery charging, such as when extra energy is stored in the
battery when coasting or braking. The down arrow indicates battery
discharging such as when the battery provides extra power to boost the
vehicle’s acceleration.

Engage and Empower instrument cluster levels only: A circular
symbol appears in the center of the gauge when energy is being
recaptured through the regenerative braking system. This indicates that
your hybrid vehicle is capturing and using energy that would have been

Instrument Cluster

lost in a conventional vehicle. The regenerative braking system can be
activated by braking or coasting (i.e. even when you’re not pressing the
brake pedal).

Fuel gauge: With the ignition on,
this gauge indicates approximately
how much fuel is left in the fuel
tank. The fuel gauge may vary
slightly when the vehicle is in
motion or on a grade. When fuel
level becomes low (50 miles [80km]
to empty), the level indicator will
change to yellow. When fuel level
becomes critically low (0 miles
[0 km] to empty), the level indicator
will change to red.

The fuel icon with the arrow points to the side of the vehicle that the
fuel filler door is on.

Refer to Filling the tank in the Maintenance and Specifications
chapter for more information.

Instantaneous fuel economy
gauge: The instantaneous fuel
economy is displayed in miles per
gallon (or liters per 100 kilometers)
from 0 to 60 mpg (or 0 to
30 L/100km). Your vehicle must be
moving to calculate instantaneous
fuel economy. If your instantaneous
fuel economy is greater than
60 mpg, a “+” sign will be displayed
next to the 60, indicating that the
current value is above the maximum that the graph can display.
Instantaneous fuel economy cannot be reset. You may turn this gauge on
or off at any information level. Refer to Message center in this chapter
for more information.

Efficiency information gauge: You have three choices for displaying
efficiency information: Efficiency Leaves, History Graph, or No Efficiency
Information. You may make this selection at any information level. Refer
to Message center in this chapter for more information on choosing the
efficiency displays.

2010 Milan Hybrid (hmv)
Owners Guide, 1st Printing
USA (fus)

Instrument Cluster

Efficiency leaves: Indicates short
term driving efficiency, measured
over the last few minutes. The more
leaves and vines that are displayed,
the more efficiently you’re driving.
Leaves and vines will occasionally
appear and disappear to indicate a
change in driving efficiency.

Note: The efficiency display can be
impacted by your use of brakes,
accelerator and accessories as well
as environmental conditions such as terrain and weather.

History graph: Indicates average
fuel economy in 10, 20, or
60 minute intervals. You can choose
the interval using the message
center. The graph is updated each
minute with the fuel economy that
was achieved during the prior 1, 2,
or 6 minutes of driving, respectively.
Each new average will be added to
the left side of the graph, shifting
the past data to the right. When the
graph area is full, the right most point will be deleted, keeping a running
scroll with the bar on the left being the most recent. Note that previous
values will remain when the vehicle is shut off and restarted, but values
from a previous drive cycle will be grayed out. The average fuel economy
since the last reset, or last 2,000 miles (3,200 km) of driving, is shown as
a horizontal line across the bar graph.
Refer to Message center in this chapter for more information on the
history graph display mode.

No efficiency information: If you choose, you may turn off both the
Efficiency leaves and History Graph using the message center. In this
case, the portion of your instrument cluster devoted to this information
will be blank.
Refer to Message center in this chapter for more information on
choosing no efficiency information.

Average fuel economy: Your average fuel economy in miles/gallon will
be displayed at the top right of your vehicle’s instrument cluster or in
liters/100 km at the lower right along with the efficiency leaves, history
graph or no display (shown previously with history graph). You may

Instrument Cluster

reset this average at any time. Refer to Message center in this chapter
for more information on the average fuel economy display mode.

If you calculate your average fuel economy by dividing distance traveled
by amount of fuel used, your figure may be different than displayed for
the following reasons:
• Your vehicle was not perfectly level during fill-up
• Differences in the automatic shut-off points on the fuel pumps at

service stations

• Variations in top-off procedure from one fill-up to another
• Rounding of the displayed values to the nearest 0.1 gallon (liter)
To determine your average highway fuel economy, do the following:

1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.

2. Record the highway fuel economy for future reference.

It is important to press the RESET button to reset the function after
setting the speed control to get accurate highway fuel economy readings.

For more information refer to Essentials of good fuel economy in the
Maintenance and Specifications chapter.

Distance to empty (DTE): Distance to Empty is displayed in the lower
right for miles or on the top right for kilometers of your vehicle’s
instrument cluster along with the efficiency, history graph or no display
(shown previously with history graph). This function will give you an
estimate of how far you can drive with the fuel remaining in your tank
under normal driving conditions. Distance to empty will vary according
to your driving habits.

DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 500 miles (800 km). This value is not
the same as the average fuel economy display. The running average fuel
economy is re-initialized to a factory default value if the battery is
disconnected.

Turn your vehicle off when refuelling to correctly detect the amount fuel
being added and allow this feature to work correctly.

Refer to Message center in this chapter for more information on the
distance to empty display mode.

can see the level of this gauge change by turning accessories on and off.

Vehicle power gauge (Empower
instrument cluster only): When
the transmission is in drive gear
only, this gauge shows you vehicle
power demand and gasoline engine
on/off threshold. It is designed to
show you how close you are to the
gasoline engine on/off threshold and
how much power you are requesting
by how much you press on the
accelerator pedal.

The red level indicator shows vehicle power demand. The more you
press on the accelerator pedal, the more power you demand of the
vehicle. The green box shows the gasoline engine on/off threshold. If
vehicle power demand is reduced, the gasoline engine will turn off when
the red level indicator moves below the green box. In this case, the
hybrid system is operating in electric vehicle mode and

⬙EV⬙ is displayed

at the bottom of the gauge. When the red level indicator exceeds the
threshold, the system commands the gasoline engine on (and the
