2023 FORD EXPLORER wiring

This system provides an improved overalllevel of frontal crash protection to frontseat occupants and is designed to helpfurther reduce the risk of airbag-relatedinjuries. The system analyzes differentoccupant conditions and crash severitybefore activating the appropriate safetydevices to help better protect occupantsin a variety of frontal crash situations.
Your vehicle's Personal Safety Systemconsists of:
•Driver and passenger dual-stage airbagsupplemental restraints.
•Front seat outermost seatbelts withpretensioners, energy managementretractors and seatbelt usage sensors.
•Front passenger sensing system.
•Passenger airbag off and on indicators.
•Front crash severity sensors.
•Restraints control module with impactand safing sensors.
•Restraint system warning light andtone.
•The electrical wiring for the airbags,crash sensors, seatbelt pretensioners,front seatbelt usage sensors, frontpassenger sensing system andindicator lights.
How Does the Personal SafetySystem Work?
The Personal Safety System can adapt thedeployment strategy of the safety devicesaccording to crash severity and occupantconditions. A collection of crash andoccupant sensors provides information tothe restraints control module. During acrash, the restraints control module maydeploy the seatbelt pretensioners, one orboth stages of the dual-stage airbagsbased on crash severity and occupantconditions.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
•Consult your local motor vehicle lawsfor towing a trailer.
•See the instructions included withtowing accessories for the properinstallation and adjustmentspecifications.
•Service your vehicle more frequently ifyou tow a trailer. See ScheduledMaintenance (page 476).
•If you use a rental trailer, follow theinstructions the rental agency givesyou.
You can find information on loadspecification terms found on the tire labeland Safety Compliance label as well asinstructions on calculating your vehicle'sload in the Load Carrying chapter. SeeLoad Limit (page 277).
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle.
Distribute the trailer load so 10-15% of thetotal trailer weight is on the tongue.
A weight distributing hitch is not requiredfor your vehicle.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to thehook retainers of your vehicle hitch.
To connect the trailer’s safety chains, crossthem under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Safe control of towed vehicles requiresseparate functioning brake systems forvehicles and trailers weighing more than1,500 lb (680 kg) when loaded.
Trailer Lamps
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
Most towed vehicles require trailer lamps.Make sure all running lights, brake lights,direction indicators and hazard flashersare working.

Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing 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 thegearshift in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.
2.Set your vehicle parking brake.
3.Place the automatic transmission inpark (P).
4.Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytimethe rear axle has been submerged in water.Water may have contaminated the rearaxle lubricant, which is not normallychecked or changed unless a leak issuspected or other axle repair is required.
