warning light FORD EXPLORER 2023 Service Manual

Note:You do not need to enter an exacttrailer width measurement. You only needto confirm that the width of the trailer is8.2 ft (2.5 m) or less.
If no, the system turns off.
If yes, the menu goes to the next screen.
•Enter length of trailer:
Toggling up or down using the menubuttons increases or decreases themeasurement by 1 ft (0.3 m). Select alength that is equal to or within 1 ft (0.3 m)of the actual measured length. Forexample, if the actual measured length is25 ft (7.6 m), toggle the length in the menuto 25 ft (8 m). When you enter the lengthof the trailer, this saves the system setup.
Note:When you connect a trailer, but donot setup a trailer in the blind spotinformation system, the system turns offand a warning appears in the informationdisplay.
Note:If the trailer is a bike rack or cargorack with electrical lighting, enter a lengthof 3 ft (1 m). Cross Traffic Alert remains onfor trailers with a length of 3 ft (1 m) or less.
Note:The system requires propermeasurement and measurement entry tofunction as designed.
System Operation
If you select a trailer in the informationdisplay prior to connecting a trailer, thesystem loads that configuration and theinformation display shows a messagewhen you connect the trailer. A secondmessage appears stating cross traffic alertis off, unless a trailer is set up with a lengthof 3 ft (1 m). The blind spot informationsystem with trailer tow still functionsnormally when driving forward.
If you connect a trailer, a message appearsindicating that you attached a trailer. If youhave not selected a trailer previously,another message appears requesting youto select one of the trailers in the list or adda new trailer. The blind spot informationsystem with trailer tow does not functionwithout a trailer selected. If you do notselect a trailer, a message appears in theinformation display stating the system hasturned this feature off.This message mightnot appear until your vehicle speed reaches22 mph (35 km/h).
The blind spot information system withtrailer tow activates when driving forwardfor that particular trailer set up. If you cyclethe ignition, the blind spot informationsystem with trailer tow continues tofunction using the last trailer you selected.
Trailer Considerations
The system works with a trailer with a frontwidth of 8.2 ft (2.5 m) or less, and a totallength from the trailer hitch ball to the rearof the trailer of 33 ft (10 m) or less.
Some trailers could cause a slight changein system performance:
•Wide box trailers, especially thosewider than the towing vehicle, couldcause false alerts to occur when drivingnext to infrastructure or near parkedcars. A false alert could also occurwhile making a 90-degree turn ordriving through a roundabout.
•Wide trailers that have a total lengthgreater than 20 ft (6 m) could causedelayed alerts when a vehicle ispassing at high speeds.

Using the Pre-Collision AssistSystem
The system is active at speeds aboveapproximately 3 mph (5 km/h) andpedestrian detection is active at speedsup to 50 mph (80 km/h).
If your vehicle is rapidly approachinganother stationary vehicle, a vehicletraveling in the same direction as yours, ora pedestrian within your driving path, thesystem design provides three levels offunctionality:
1.Alert.
2.Brake Support.
3.Active Braking.
Alert: When active, a flashing visualwarning appears and an audible warningtone sounds.
Brake Support: The system design helpsreduce the impact speed by preparing thebrakes for rapid braking. Brake supportdoes not automatically apply the brakes.If you press the brake pedal, the systemcould apply additional braking up tomaximum braking force, even if you lightlypress the brake pedal.
Active Braking: Active braking mayactivate if the system determines that acollision is imminent. The system may helpthe driver reduce impact damage or avoidthe crash completely.

TOWING A TRAILER
WARNING: Towing trailersbeyond the maximumrecommended gross trailerweight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss ofvehicle control, vehicle rolloverand personal injury.
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
Note: See RecommendedTowing Weights (page 284).
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See Fuses(page 305).
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a ball mount with thecorrect rise or drop and loadcapacity. When both theloaded vehicle and trailer areconnected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page277).
You can also find information inthe RV & Trailer Towing Guideavailable at your authorizeddealer, or online.

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.
