TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a 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 tow 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 regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page176). You can also find theinformation in the RV & TrailerTowing Guide, available at anauthorized dealer.

•If you or an authorized Ford dealer addany non-Ford custom electrical orelectronic accessories or componentsto your vehicle, you may adverselyaffect battery performance anddurability. In addition, you may alsoadversely affect the performance ofother electrical systems in the vehicle.
AUXILIARY SWITCHES
The auxiliary switchboard on the centerconsole makes aftermarket customizationeasier, with four prewired switchesattached to the power distribution box forelectrical accessories.
These switches are labeled AUX 1,AUX2,AUX 3 and AUX 4. They will onlyoperate while the ignition is in the onposition, whether the engine is running ornot. It is, however, recommended that theengine remain running to maintain abattery charge when using the switchesfor an extended duration or higher currentdraws. When switched on by the operatorthey provide 10 amps, 15 amps or 30 ampsof electrical battery power for a variety ofuses.
The switches control relays and fuses thatare located under the hood in the auxiliaryswitch pass through circuits.
