battery FORD EXPLORER 2023 Service Manual

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn. Have your vehiclechecked. If the vehicle has continuousvibration or shudder in the steering wheelwhile braking, have your vehicle checked.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. Wet brakes result in reducedbraking efficiency. Gently press the brakepedal a few times when driving from a carwash or standing water to dry the brakes.
See Cleaning the Wheels (page 344).
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. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement. If none are found and thecondition persists, have your vehiclechecked. If your vehicle has to be towed,we recommend that you contact aprofessional towing service.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional.
If the warning lamp does not illuminateduring start up, remains on or flashes, thesystem may be disabled. Have the systemchecked. If the anti-lock brake system isdisabled, normal braking is still operational.
See Warning Lamps and Indicators(page 105).
Note:Indicators vary depending on region.
This lamp illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or if it begins to flashat any time except the time during applyingor releasing the parking brake, have thesystem checked.
Regenerative Braking System
This feature simulates the engine brakingof an internal combustion engine andassist the standard brake system whilerecovering some of the energy of motionand storing it in the battery to improve fueleconomy. The standard brake system isdesigned to fully stop the car ifregenerative braking is not available.During regenerative braking, the motor isspun as a generator to create electricalcurrent. This recharges the battery andslows the vehicle. Once the acceleratorpedal is released, the motor changes froman energy user to an energy producer.

When you release the accelerator pedal orpress the brake pedal, the brake controllerautomatically detects the amount ofdeceleration requested and optimizes howmuch of the deceleration will be producedby regenerative braking. The remainingportion is generated by standard frictionbraking. When the battery is almost fullycharged, the amount of regenerativebraking is limited to avoid overcharging,and the requested deceleration isproduced by standard friction brakingalone.
Regenerative braking does not take theplace of the standard friction brakes; it onlyassists them. Regenerative braking isdesigned to interact with the anti-lockbrake system. Regenerative brakingdisables when the anti-lock brake systemis activated or the battery is fully charged.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks 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 may travel further.Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.

Possible CauseSymptom
There is not enough space for the parking maneuver onthe opposite side of the parking space.
The parking space is more than 5 ft (1.5 m) or less than2 ft (0.5 m) away.
The vehicle speed is greater than 22 mph (35 km/h)for parallel parking or greater than 19 mph (30 km/h)for perpendicular parking.
You recently disconnected or replaced the battery. Afteryou reconnect the battery you must drive your vehicleon a straight road for a short period of time.
An irregular curb along the parking space prevents thesystem from correctly aligning your vehicle.The system does not correctlyposition your vehicle in aparking space.Vehicles or objects bordering the space may not becorrectly parked.
Your vehicle stopped too far past the parking space.
The tires may not be correctly installed or maintained.For example, not inflated correctly, improper size, or ofdifferent sizes.
A repair or alteration changes the detection capabilities.
A parked vehicle has a high attachment. For example,a salt sprayer, snowplow or moving truck bed.
The parking space length or position of parked objectschanges after your vehicle passes the space.
You are using a spare tire or a tire more significantlyworn than the other tires.
The temperature around your vehicle quickly changes.For example, driving from a heated garage into coldoutside temperature, or after leaving a car wash.

STEERING
Electric Power Steering
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the ignition off. After at least 10seconds, switch the ignition on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem, there is no fluid reservoir, nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires 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.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Adaptive Learning (If Equipped)
The electronic power steering systemadaptive learning helps correct roadirregularities and improves overall handlingand steering feel. It communicates withthe brake system to help operateadvanced stability control and accidentavoidance systems. Additionally, wheneverthe battery is disconnected or a newbattery installed, you must drive yourvehicle a short distance before the systemrelearns the strategy and reactivates allsystems.
PRE-COLLISION ASSIST
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.
