WHAT IS A HYBRID ELECTRIC
VEHICLE
A hybrid vehicle has an electric motor anda high voltage battery combined with agasoline engine.
HOW DOES A HYBRID
ELECTRIC VEHICLE WORK
The hybrid vehicle combines electric andgasoline propulsion to provide optimalperformance and improved efficiency.
HYBRID ELECTRIC VEHICLE
DRIVING CHARACTERISTICS
The gasoline engine starts and stops toprovide power when required and to savefuel when not needed. When coasting atlow speeds, coming to a stop or standing,the gas engine normally shuts down andyour vehicle operates in electric-onlymode.
Conditions that may cause the gasolineengine to start or remain running include:
•Considerable vehicle acceleration.
•Driving uphill.
•The high voltage battery charge levelis low.
•Heating or cooling the vehicle interiorin high or low outside temperatures.
•The gasoline engine is below normaloperating temperature.
•Towing a trailer.
•Certain selectable drive modes couldcause the engine to run. See Selectinga Drive Mode (page 363). Use of thepaddle shifters while in drive (D) couldcause the engine to run.
Your hybrid vehicle also comes withstandard hydraulic braking andregenerative braking. Regenerative brakingis performed by your transmission andcaptures brake energy and stores it in thehigh voltage battery.
You could also notice that your enginecontinues to run instead of shutting offduring extended downhill driving. Theengine stays on during this engine brakingbut is not using any fuel.
You could also hear a slight whine orwhistle when operating your vehicle. Thisis the normal operation of the electricmotor in the hybrid system.
HYBRID ELECTRIC VEHICLE
INDICATORS
When you start your vehicle, agreen READY indicator lightappears in the instrument clusterletting you know that your vehicle is readyfor driving.
The engine may not start because yourvehicle has a silent key start feature. Thisfuel saving feature allows your vehicle tobe ready to drive without requiring the gasengine to be running.
The indicator remains on when your vehicleis on, whether the engine is running or not,to indicate your vehicle is capable ofmovement using the electric motor, gasengine or both.
Typically, the engine does not start unlessthe vehicle is cold, a climate controlchange is requested or you press theaccelerator pedal.

Your vehicle may have a temporary orconventional spare tire. A temporary sparetire is different in diameter or width,tread-type, or is from a differentmanufacturer than the road tires on yourvehicle. Consult information on the tirelabel or Safety Compliance label forlimitations when using.
When towing a trailer:
•Obey country specific regulations fortowing a trailer.
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engineand transmission cooling and to helpA/C performance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off when you aretowing on long, steep slopes.
•Shift to a lower gear when driving downa long or steep hill. Do not continuouslyapply the brakes, as they may overheatand become less effective.
•If your transmission has Grade Assistor Tow/Haul, use this feature whentowing. This provides engine brakingand helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•Your vehicle has AdvanceTrac with rollstability control. When towing a trailer,additional loads could cause theAdvanceTrac system to engage duringcornering maneuvers. Reduce corneringspeeds to make sure that you canmaintain control of the vehicle andtrailer if the AdvanceTrac systemengages.
•Allow more distance for stopping witha trailer attached. Anticipate stops andgradually brake.
•Avoid parking on a slope. However, ifyou must park on a slope, turn thesteering wheel to point your vehicletires away from traffic flow, set theparking brake, place the transmissionin park (P) and place wheel chocks infront and back of the trailer wheels.
Note:Chocks are not included with yourvehicle.

Driving In Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.
Driving In Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud.
After driving through mud, clean yourvehicle. Excess mud stuck on the wheelsand tires and rotating components cancause an imbalance and result in damage.
Note:The vehicle brakes are less effectivewhen wet or muddy.
Driving Over Rocks and Gravel
Never attempt to straddle a rock that islarge enough to strike your axles orundercarriage.
Leave a generous gap between yourvehicle and other vehicles to minimize therisk of damage. Avoid dust clouds as theyreduce visibility.
Climbing A Hill
WARNING: Extreme care shouldbe used when steering the vehicle inreverse down a slope so as not to causethe vehicle to swerve out of control.
Do not drive over the crest of a hill withoutseeing what conditions are on the otherside. Do not drive in reverse over a hillwithout the aid of an observer.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.
Note:Too much acceleration can causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Driving Through Water
WARNING: Do not attempt tocross a deep, fast flowing body of water.Failure to follow this instruction couldresult in the loss of control of yourvehicle, personal injury or death.
The key to a safe crossing is the waterdepth, current and bottom of the water'scondition. On soft bottoms, the vehiclesinks in, effectively increasing the waterlevel on the vehicle. Make sure to considerthis when determining the depth of water.
Determine the depth and speed of thecurrent before attempting a water crossing.
Be aware that obstacles and debris couldbe beneath the water’s surface.
Note:Cross flowing water at an angleheading slightly upstream.
Note:Tread lightly and avoid damage tothe environment.
Water can cause permanent damage thatmay not be covered by your vehiclewarranty. See Driving Through WaterLimitations (page 470).
Note:Failure to follow the recommendedspeeds can result in vehicle damage.
Muddy waters can reduce the coolingsystem effectiveness by depositing debrisinto the radiator.
High currents even in shallow water canwash the dirt out from around your tires orpush your vehicle across slippery rocks orsurfaces.
Do not cross any body of water that is fastflowing and rising.

ENGINE OIL CAPACITY ANDSPECIFICATION
For filling information, please refer to theCapacities and Specifications section ofyour owner's manual. See Engine OilCapacity and Specification (page 506).
CHECKING THE COOLANT
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 667).
Note:Make sure that the coolant level isbetween the minimum and maximum markson the coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Keep your hands andclothing clear of the cooling fan.

2023 F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202206, DOMMaintenance

WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Note:Automotive fluids are notinterchangeable.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 578). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and couldvoid the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized ordistilled water. See Capacities andSpecifications (page 578). Using water thathas not been deionized may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant toreach the correct level.
Note:We do not recommend the use ofrecycled coolant.
3.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
4.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, repeat step2.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.Service your vehicle as soon as possible.
