ELECTRIC VEHICLE (PHEV)
WARNING: When refueling always
shut the engine off and never allow sparks
or open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes.
WARNING: The fuel system may be
under pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury.
WARNING: Do not pry open the fuel
tank filler valve. This could damage the fuel
system. Failure to follow this instruction
could result in fire, personal injury or death.
WARNING: Do not remove the fuel
pump nozzle from its fully inserted position
when refueling.
WARNING: Stop refueling when the
fuel pump nozzle automatically shuts off
for the first time. Failure to follow this will
fill the expansion space in the fuel tank and
could lead to fuel overflowing.
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire.
WARNING: Wait at least five seconds
before removing the fuel pump nozzle to
allow any residual fuel to drain into the fuel
tank.
WARNING: Read and follow all the

FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank when the fuel gauge indicates empty.
See Capacities and Specifications (page
465).
In addition, the fuel tank contains an empty
reserve. The empty reserve is an unspecified
amount of fuel that remains in the fuel tank
when the fuel gauge indicates empty.
Note:The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Calculating Fuel Economy
Your vehicle calculates fuel economy figures
through the trip computer average fuel
function. See Information Displays (page
136).The first 1,000 mi (1,600 km) of driving is the
break-in period of the vehicle. Resetting
average fuel in your trip computer after
2,000–3,000 mi (3,200–4,800 km) provides
a more accurate measurement.

Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Note:Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
• Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection.
• Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
460).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
• Engine power is limited.
• The air conditioning system turns off.

Maintenance

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the
battery or terminals, remove the cables from
the terminals and clean with a wire brush.
You can neutralize the acid with a solution
of baking soda and water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
If you replace the battery make sure it
matches the electrical requirements of your
vehicle.If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Battery Sensor Reset
When you install a new battery, reset the
battery sensor by doing the following:
1. Switch the ignition on, and leave the
engine off.
Note:Complete Steps 2 and 3 within 10
seconds.
2. Flash the high beam headlamps five
times, ending with the high beams off.
3. Press and release the brake pedal three
times.
The battery warning lamp flashes three times
to confirm that the reset is successful.
Battery Management System (If Equipped)
The system monitors battery conditions and
takes actions to extend battery life. If
excessive battery drain is detected, the
system temporarily disables some electrical
systems to protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active. This message is only for
notification that an action is taking place, and
not intended to indicate an electrical problem
or that the battery requires replacement.

Maintenance

After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time, your vehicle must remain fully
locked with the ignition switched off.
Note:Prior to relearning the battery state of
charge, the battery management system
may temporarily disable some electrical
systems.
Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection directly
to the battery negative post. This can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.
Note:If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.Remove and Reinstall the Battery
