relay FORD E SERIES 2019 Owners Manual

TOWING A TRAILER
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
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.
Your vehicle may have electricalitems, for example fuses or relays,related to towing. See Fuses(page 131).
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading your vehicle.
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 draw bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, 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 regardingcorrect trailer loading and settingyour vehicle up for towing islocated in another chapter of thisOwner's Manual. See Load Limit(page 99). You can also find theinformation in the RV & TrailerTowing Guide. See an authorizeddealer.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNING: Always disconnect thebattery before servicing high currentfuses.
WARNING: To reduce risk ofelectrical shock, always replace thecover to the power distribution boxbefore reconnecting the battery orrefilling fluid reservoirs.
Note:If your vehicle is equipped with dualbatteries, disconnecting the primaryunder-hood battery does not remove powerfrom all circuits.
The power distribution box is in the enginecompartment. It has high-current fusesthat protect your vehicle's main electricalsystems from overloads.
If the battery has been disconnected andreconnected, you need to reset somefeatures. See Changing the 12V Battery(page 153).

•An authorized dealer needs to installmobile communications systems.Improper installation may harm theoperation of your vehicle, particularlyif the manufacturer did not design themobile communication systemspecifically for automotive use.
•If you or an authorized Ford dealer addany non-Ford electrical or electronicaccessories or components to yourvehicle, you may adversely affectbattery performance and durability. Inaddition, you may also adversely affectthe performance of other electricalsystems in the vehicle.
AUXILIARY SWITCHES
For maximum vehicle performance, keepthe following information in mind whenadding accessories or equipment to yourvehicle:
•When adding accessories, equipment,passengers and luggage to yourvehicle, do not exceed the total weightcapacity of the vehicle or of the frontor rear axle (GVWR or GAWR asindicated on the Safety ComplianceCertification label). Ask an authorizeddealer for specific weight information.
•The Federal CommunicationsCommission (FCC) and CanadianRadio TelecommunicationsCommission (CRTC) regulate the useof mobile communications systemsequipped with radio transmitters, forexample, two-way radios, telephonesand theft alarms. Any such equipmentinstalled in your vehicle should complywith Federal CommunicationsCommission (FCC) and CanadianRadio TelecommunicationsCommission (CRTC) regulations, andshould be installed by an authorizeddealer.
•An authorized dealer needs to installmobile communications systems.Improper installation may harm theoperation of your vehicle, particularlyif the manufacturer did not design themobile communication systemspecifically for automotive use.
•If you or an authorized Ford dealer addany non-Ford electrical or electronicaccessories or components to yourvehicle, you may adversely affectbattery performance and durability. Inaddition, you may also adversely affectthe performance of other electricalsystems in the vehicle.
The auxiliary switch option packageprovides four switches, mounted in thecenter of the instrument panel. Theseswitches operate only when you switch theignition on, whether the engine is runningor not. Ford recommends, however, thatthe engine remain running to maintainbattery charge when using the auxiliaryswitches for extended periods of time orhigher current draws.
When switched on, the auxiliary switchesprovide 10 amps, 15 amps or 30 amps ofelectrical battery power for a variety ofpersonal or commercial uses.
The switches include the fuse and relay kit.This kit contains the required fuses andrelays that an authorized technician needsto install into the power distribution box,located under the hood. Refer to theinstruction sketch included in the kit.Contact an authorized dealer for service.
