engine FORD BRONCO 2022 Service Manual

Note:You can only move the gearshift leverto crawler (C) by raising the collar belowthe gearshift knob up before shifting tocrawler. This is a lockout feature whichprotects the transmission from accidentallyengaging crawler (C) when intending toselect second (2).
If crawler (C) is not fully engaged press theclutch pedal down, return the gearshift tothe neutral position, then release the clutchpedal. Re-apply the clutch pedal, then liftthe gearshift collar and shift into crawler(C) again.
The crawler gear enables an easier start inunusual conditions or terrain. You shouldchange up to first (1) when possible andrefrain from using crawler (C) at highengine speeds as transmission damagecould result. See Manual TransmissionPrecautions (page 174).
In normal use, ensure your vehicle isstationary before selecting crawler (C) asit is primarily a starting gear. If you changedown to crawler (C) from first (1) while thevehicle is moving, ensure an engine speedis below 1500 rpm, and that the clutchpedal is fully pressed for a smoothtransition to crawler gear.
RECOMMENDED SHIFT
SPEEDS
Recommended Shift Speeds
For best fuel efficiency when driving yourvehicle, shift to the next gear by 3000RPM.
Shifting at a higher RPM such as3000-6000 RPM can increase theperformance capabilities of the vehicle.However, higher engine and transmissionspeeds can increase wear and reduce fueleconomy.
When downshifting your vehicle, alwaysshift at the lowest engine RPM possible tomatch your driving conditions. This isusually under 2000 RPM for all forwardgears, except for downshifting into thecrawler (C) gear which you should dobelow 1500 RPM. See ManualTransmission Precautions (page 174).
Note:Always fully depress the clutch pedalbetween gear shifts.

MANUALLY SHIFTING GEARS
SHIFTING USING THE BUTTONSON THE SELECTOR LEVER
Your vehicle has a SelectShift Automatictransmission gearshift lever. This gives youthe ability to change gears up or down,without a clutch, as preferred.
To prevent the engine from running at toolow an RPM, which could cause it to stall,SelectShift still makes some downshiftsif it determines that you have notdownshifted in time. Although SelectShiftmakes some downshifts for you, it stillallows you to downshift at any time if itdetermines that damage to the enginefrom over-revving does not occur.
Note:SelectShift does not automaticallyupshift, even if the engine is approachingthe RPM limit. Shift manually by pressingthe + button.
Note:Engine damage could occur if youmaintain excessive engine revving withoutshifting.

BRAKE PRECAUTIONS
WARNING: Driving your vehiclewith the warning lamp on is dangerous.A significant decrease in brakingperformance may occur. It may take youlonger to stop your vehicle. Have yourvehicle checked as soon as possible.Driving extended distances with theparking brake engaged can cause brakefailure and the risk of personal injury.
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash ordriving from standing water to dry thebrakes.
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, the stoplampscould flash during heavy braking. Followingthis the hazard warning flashers could alsoturn on when your vehicle comes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEMLIMITATIONS
The anti-lock braking system does noteliminate the risk of crash when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and travel further.Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.

WHAT IS TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed,reduces engine power at the same time toincrease traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system turns on each time you switchthe ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Switching the System Off
The switch for the stability andtraction control system is on theinstrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Note:When you switch traction control off,stability control remains fully active.
Note:When you place your vehicle intofour-wheel drive low (4L), the tractioncontrol disables. Traction control resumeswhen you put your vehicle back intotwo-wheel drive or four-wheel drive high(4H).
Note:For additional information on thetraction and stability control systems. SeeStability Control (page 204).

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo speakers mayinterfere with and adversely affect theelectronic stability control system.Reducing the effectiveness of theelectronic stability control system couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death.
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.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or moreof the wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances yourvehicle’s ability to prevent rollovers bydetecting your vehicle’s roll motion andthe rate at which it changes by applyingthe brakes to one or more wheelsindividually.
Curve Control
Curve control enhances your vehicle’sability to follow the road when corneringseverely or avoiding objects in the roadway.Curve control operates by reducing enginepower and, if necessary, applying brakesto one or more of the wheels individually.
