2023 FORD F150 coolant

HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.
Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C).
USING THE ENGINE BLOCKHEATER
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the engine block heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.
STOPPING THE ENGINE
STOPPING THE ENGINE WHENYOUR VEHICLE IS STATIONARY -VEHICLES WITHOUT: PUSHBUTTON START
1.Shift into park (P).
2.Apply the parking brake.
3.Wait until the engine reaches idlespeed.
4.Turn the key to position 0.
STOPPING THE ENGINE WHENYOUR VEHICLE IS STATIONARY -VEHICLES WITH: PUSH BUTTONSTART
1.Shift into park (P).
2.Apply the parking brake.
3.Wait until the engine reaches idlespeed.
4.Press the push button ignition switch.
STOPPING THE ENGINE WHENYOUR VEHICLE IS MOVING -VEHICLES WITHOUT: PUSHBUTTON START
WARNING: Switching off theengine when your vehicle is still movingresults in a significant decrease inbraking assistance. Higher effort isrequired to apply the brakes and to stopyour vehicle. A significant decrease insteering assistance could also occur. Thesteering does not lock, but higher effort

INFORMATION –
TROUBLESHOOTING
HYBRID ELECTRIC VEHICLEINFORMATION – FREQUENTLYASKED QUESTIONS
What should I do if the vehicle runs outof fuel and the high voltage battery isout of charge?
Refuel and start your vehicle normally.The engine will recharge the highvoltage battery.
Why does the engine sometimes startat key-on?
The vehicle's computer determines ifan engine start is required at key-on.It starts the engine when necessary forcabin heating, windshield defrost, or ifthe outside temperature is low.
Can I put E15 or E85 in my vehicle, andhow will it affect my fuel economy?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but youmay notice slightly reduced fueleconomy because ethanol containsless energy per gallon than gasoline.Your hybrid vehicle is not designed touse E85 (85% ethanol).
Why does it take a long time before theengine shuts down?
There are several reasons the enginestays on for an extended amount oftime when you first start it. Onecommon reason is to make sure thatthe emissions components are warmenough to minimize tailpipe emission.As the climate gets cooler, theengine-on time is extended.
Why does my engine stay on when it isextremely cold outside?
In order to make sure that the climatecontrol system can begin heating thecabin or defrosting the windshield assoon as a driver requests it, the enginecoolant temperature has to be keptsufficiently hot. Keeping the engine onis required to maintain the correctcoolant temperature.
POWER FLOW
WHAT IS POWER FLOW
The power flow shows how power is beingused in the vehicle and also displaysreasons for engine operation.
HOW DOES POWER FLOW WORK
The power flow information foryour hybrid vehicle is availablethrough the home screen orunder Apps.
Vehicle Operational States
Power flows to or from the front and rearwheels depending on the operational stateand the drive conditions.
•Idling: The vehicle is running and in park(P). The engine and/or the high voltagebattery are on.
•Electric driving: The vehicle is runningand in drive (D) or neutral (N). The highvoltage battery provides power to thewheels.
