2023 FORD BRONCO engine

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 ambienttemperature. If this occurs, there is noneed to stop your vehicle. You cancontinue to drive.
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.

WARNING: This vehicle may havemore than one battery. Removing thebattery cables from only one batterydoes not disconnect your vehicleelectrical system. Make sure youdisconnect the battery cables from allbatteries when disconnecting power.Failure to do so may cause seriouspersonal injury or property damage.
WARNING: For vehicles withAuto-Start-Stop the battery requirementis different. You must replace the batterywith one of exactly the samespecification.
WHAT IS THE BATTERYMANAGEMENT SYSTEM
The battery management system monitorsbattery conditions and takes actions toextend battery life.
HOW DOES THE BATTERYMANAGEMENT SYSTEM WORK
If excessive battery drain is detected, thesystem temporarily disables someelectrical systems to protect the battery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message could appear in the informationdisplay to alert you that battery protectionactions are active. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
BATTERY MANAGEMENT SYSTEMLIMITATIONS
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemcould temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it couldadversely affect battery performance anddurability. This could also affect theperformance of other electrical systems inthe vehicle.
CHANGING THE 12V BATTERY
The battery is in the engine compartment.See Maintenance (page 349).
Your vehicle has a maintenance-freebattery. It does not require additionalwater during service.

If any corrosion ispresent on the battery or terminals, removethe cables from the terminals and cleanwith a wire brush. You can neutralize theacid with a solution of baking soda andwater.
We recommend that you disconnect thenegative battery cable terminal from thebattery if you plan to store your vehicle foran extended period.
Note:If you only disconnect the negativebattery cable terminal, make sure it isisolated or placed away from the batteryterminal to avoid unintended connection orarcing.
If you disconnect or replace the batteryand your vehicle has an automatictransmission, it must relearn its adaptivestrategy. Because of this, the transmissionmay shift firmly when first driven. This isnormal operation while the transmissionfully updates its operation to optimumshift feel.
Removing the Battery
1.Apply the parking brake and switch theignition off.
2.Switch all electrical equipment off, forexample lights and radio.
3.Wait a minimum of two minutes beforedisconnecting the battery.
Note:The engine management system hasa power hold function and remains poweredfor a period of time after you switch theignition off. This is to allow diagnostic andadaptive tables to be stored. Disconnectingthe battery without waiting can causedamage not covered by the vehicleWarranty.
4.Disconnect and isolate the negativebattery cable terminal.
5.Disconnect and isolate the positivebattery cable terminal.
6.Remove the battery securing clamp.
7.Remove the battery.
If you disconnect or replace the vehiclebattery, you must reset the followingfeatures:
•Window bounce-back. See WindowBounce-Back (page 114).
•Clock Settings.

DetailsMessage
The battery management system determines that the 12Vbattery is at a low state of charge. Start the engine to chargethe battery or charge the battery using an aftermarket batterycharger. Always use the vehicle ground point when connectingthe negative cable of the external battery charger. See JumpStarting the Vehicle (page 330). This message clears onceyou restart your vehicle and the battery state of charge hasrecovered. Do not switch on the ignition when a batterycharger is in use to charge the battery.
Battery State of ChargeLow
The battery management system determines that the batteryis at a low state of charge. Turn the ignition off as soon aspossible to protect the battery. This message will clear oncethe vehicle has been started and the battery state of chargehas recovered. Turning off unnecessary electrical loads willallow faster battery state-of-charge recovery.
Turn Power Off To SaveBattery
Displayed when the battery management system detects anextended low-voltage condition. Various vehicle features willbe disabled to help preserve the battery. Turn off as many ofthe electrical loads as soon as possible to improve systemvoltage. If the system voltage has recovered, the disabledfeatures will operate again as normal.
