Fuel Gauge
The fuel gauge indicates about how much
fuel is in the fuel tank. The arrow adjacent to the fuel pump symbol
indicates on which side of your vehicle the
fuel filler door is located.
Note:
The fuel gauge may vary slightly when
your vehicle is moving or on a slope.
Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty reaches
75 mi (120 km) to empty for MyKey, and at
50 mi (80 km), 25 mi (40 km), 10 mi (20 km)
and 0 mi (0 km) for all vehicle keys.
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal. Battery Gauge
The high voltage battery gauge displays the
total amount of charge associated with your
available electric only driving range. A full fill
represents the total amount of energy you
can get from an external charge (plugging
your vehicle in). When the fill reaches empty
the powertrain system automatically switches
to hybrid operation.
See Plug-In Hybrid
Vehicle Operation (page 222).

Vehicle Driving Range
Vehicle range indicates the estimated
distance your vehicle will travel with the
energy currently onboard. Estimates will vary
based on the energy used while driving.
Changes in driving pattern can cause the
values to not only decrease but also increase
or stay constant for periods of time.
The amount of energy being used while
driving is affected by:
•
Mild or aggressive acceleration or
braking.
• Your vehicle speed.
• Use of accessories such as climate
control. •
Ambient temperature and other weather
conditions.
• Driving in a city or on a highway.
• Driving on hilly road conditions.
Note: It is normal for vehicle range estimates
to vary due to changes in average energy
usage. This is why you typically see different
range estimates each time you fill up your
fuel tank or fully charge your battery.
Gasoline Distance to Empty
Indicates the approximate distance your
vehicle can travel on the fuel remaining in
the tank.
Electric Range
Indicates the approximate distance your
vehicle can travel on electric power only with
the engine off. Engine Coolant Temperature Gauge WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator is in the normal range. If the engine
coolant temperature exceeds the normal
range, stop your vehicle as soon as safely
possible, switch off the engine and let the
engine cool.

immediately. Do not drive if you smell
exhaust fumes. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the following:
•
Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER
(IF EQUIPPED) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING:
Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power cable
and may cause an electrical short resulting
in fire, injury and property damage.
Note: The heater is most effective when
outdoor temperatures are below
0°F (-18°C).
The heater acts as a starting aid by warming
the engine coolant. This allows the climate
control system to respond quickly. The
equipment includes a heater element
(installed in the engine block) and a wire
harness. You can connect the system to a
grounded 120-volt AC electrical source.

Answer
Question
In order to make sure that the climate control system can begin heatingthe cabin or defrosting the windshield as soon as you request it, the engine coolant temperature has to be kept sufficiently hot. Keeping
the engine on is required to maintain the correct coolant temperature.
Why does my engine stay on when it is extremely cold outside?
Your hybrid vehicle can use E15 fuel (15% ethanol, 85% gasoline), butyou could notice slightly reduced fuel economy because ethanol
contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how will it affect my fuel
economy?
The high voltage battery system is designed to last the life of thevehicle and requires no maintenance.
How long will my high voltage battery last? Does it need maintenance?
