heating FORD SUPER DUTY 2023 User Guide

The electronic torque overlay steeringsystem adds supplemental steering assistto the hydraulic gear when needed,dependent on vehicle conditions such asvehicle speed, steering wheel angle, andsteering wheel torque. The hydraulicsteering system provides the majority ofsteering assistance. The electronic torqueoverlay enables features such as pro trailerbackup assistance and lane departurewarning.
If your vehicle loses electrical power whileyou are driving, your vehicle loses electricpower steering assistance. The steeringsystem still operates, and you can steeryour vehicle with hydraulic assist. Steeringyour vehicle with only hydraulic assistrequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage tothe steering system. You do not lose theability to steer your vehicle manually.Typical steering and driving maneuversallow the system to cool and return tonormal operation.
LOCATING THE HYDRAULICPOWER STEERING FLUIDRESERVOIR
The hydraulic power steering fluid reservoiris found in the engine compartment. SeeUnder Hood Overview (page 441).
CHECKING THE HYDRAULICPOWER STEERING FLUID
Check the power steering fluid. SeeScheduled Maintenance (page 591). Ifadding fluid is necessary, use onlyMERCON LV ATF.
Check the fluid level when it is at ambienttemperature.
1.Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3.Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5.Switch the engine off.
6.Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7.If the fluid is low, add fluid in smallamounts, continuously checking thelevel until it is between the MIN andMAX range. For proper fluid type, SeeCapacities and Specifications (page520). Be sure to put the cap back on thereservoir.

HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and gouses radar and camera sensors to maintaina set gap between your vehicle and thevehicle in front of you while following it toa complete stop. Stop and go can also beset to follow a vehicle directly in front ofyou and adjust the set speed, while you areat a complete stop.
ADAPTIVE CRUISE CONTROL
PRECAUTIONS
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
WARNING: Do not use adaptivecruise control on winding roads, in heavytraffic or when the road surface isslippery. This could result in loss ofvehicle control, serious injury or death.
WARNING: Pay close attention tochanging road conditions such asentering or leaving a highway, on roadswith intersections or roundabouts, roadswithout visible lanes of travel, roads thatare winding, slippery, unpaved, or steepslopes.
WARNING: The system is not acrash warning or avoidance system.
WARNING: Do not use the systemwhen towing a trailer that hasaftermarket electronic trailer brakecontrols. Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death.
WARNING: Do not use tire sizesother than those recommended becausethis can affect the normal operation ofthe system. Failure to do so may resultin a loss of vehicle control, which couldresult in serious injury.
WARNING: Do not use the systemwith a snow plow blade installed.
WARNING: Do not use the systemin poor visibility, for example fog, heavyrain, spray or snow.
When Following a Vehicle
WARNING: When following avehicle that is braking, your vehicle doesnot always decelerate quickly enough toavoid a crash without driver intervention.Apply the brakes when necessary. Failureto follow this instruction could result inpersonal injury or death.
Hilly Condition and Trailer TowUsage
You should select a lower gear when thesystem is active in situations such asprolonged downhill driving on steep slopes,for example in mountainous areas. Thesystem needs additional engine braking inthese situations to reduce the load on thevehicle’s regular brake system to preventit from overheating.

2023 Super Duty (TFH) Canada/United States of America, enUSA, Edition date: 202211, DOMAdaptive Cruise Control (If Equipped)

We recommend the use of a wheel lift anddollies or flatbed equipment to tow yourvehicle. Vehicle damage could occur iftowed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehiclesmust have their designated drive wheelsoff the ground regardless of towingdirection. Use tow dollies to preventdamage to the transmission.
All-wheel or four-wheel drive vehiclesrequire that all wheels be off the groundusing a wheel lift and dollies or flatbedequipment. This prevents damage to thetransmission and drive system.
Note:You need to switch on the ignition tounlock the steering.
Note:Make sure you check the steeringcolumn before towing. It could lock if thebattery is dead.
FAIL-SAFE COOLING
WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs due tooverheating.
The fail-safe distance depends on outsidetemperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLINGWORK
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine.
Note:Have your vehicle checked as soonas possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODEIS ACTIVATED
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
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.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.

COOLANT
CHECKING THE COOLANT LEVEL
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: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 591).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.This is normal.
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: 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 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 allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
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 520). 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 maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionised ordistilled water. See Capacities andSpecifications (page 520). Using water thathas not been deionised may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
Note: Coolants marketed for all makes andmodels may not be approved to ourspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page520).
3.Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
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.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
CHANGING THE COOLANT
For coolant change, see your authorizeddealer.
Changing the coolant is necessary atspecific mileage intervals listed in thescheduled maintenance information. SeeScheduled Maintenance (page 591).

MANAGING THE COOLANTTEMPERATURE
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and thevehicle may not be able to acceleratewith full power until the coolanttemperature reduces.
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and outsidetemperature. If this occurs, there is noneed to stop your vehicle. You cancontinue to drive. See Fail-Safe Cooling(page 425).
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.
COOLANT – WARNING LAMPS
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone.
