Tires, Wheels and Loading -> TRAILER TOWING for Your Ford Explorer SUV Fifth Generation (2005-2011)

Tires, Wheels and Loading  
TRAILER TOWING  
Trailer towing with your vehicle may require the use of a trailer tow  
option package.  
Trailer towing puts additional loads on your vehicle’s engine,  
transmission, axle, brakes, tires, and suspension. For your safety and to  
maximize vehicle performance, be sure to use the proper equipment  
while towing.  
Follow these guidelines to ensure safe towing procedure:  
Do not tow a trailer until your vehicle has been driven at least  
1,000 miles (1600 km).  
Stay within your vehicle’s load limits.  
Thoroughly prepare your vehicle for towing. Refer to Preparing to  
tow in this chapter.  
Use extra caution when driving while trailer towing. Refer to Driving  
while you tow in this chapter.  
Service your vehicle more frequently if you tow a trailer. Refer to the  
severe duty schedule in the scheduled maintenance information.  
Refer to the instructions included with towing accessories for the  
proper installation and adjustment specifications.  
Do not exceed the maximum loads listed on the Safety Compliance  
Certification label. For load specification terms found on the label, refer  
to Vehicle loading in this chapter when figuring the total weight of your  
vehicle.  
Your vehicle is equipped with a standard Class II integrated hitch and  
requires only a draw bar and ball with a 19 mm (3/4 inch) shank  
diameter. An optional Class III/Class IV hitch is also available.  
Note: Do not exceed the GVWR or the GAWR specified on the  
certification label.  
WARNING: Towing trailers beyond the maximum recommended  
gross trailer weight exceeds the limit of the vehicle and could  
result in engine damage, transmission damage, structural damage, loss  
of vehicle control, vehicle rollover and personal injury.

Preparing to tow  
Use the proper equipment for towing a trailer and make sure it is  
properly attached to your vehicle. Contact your authorized dealer or a  
reliable trailer dealer as soon as possible if you require assistance.  
Hitches  
Do not use hitches that clamp onto the vehicle bumper. Use a load  
carrying hitch. You must distribute the load in your trailer so that  
10–15% of the total weight of the trailer is on the tongue, not to exceed  
the maximum tongue loads as stated:  
Class II receiver: 350 lb. (159 kg)  
Class III/IV receiver: 500 lb. (227 kg) (weight carrying); 740 lb.  
(336 kg) (weight distributing)  
Safety chains  
Always connect the trailer’s safety chains to the frame or hook retainers  
of the vehicle hitch. To connect the trailer’s safety chains, cross the  
chains under the trailer tongue and allow slack for turning corners.  
If you use a rental trailer, follow the instructions that the rental agency  
gives to you.

Loops can be used as recovery  
hooks.  
Do not attach safety chains to the bumper.  
Trailer brakes  
Electric brakes and manual, automatic or surge-type trailer brakes are  
safe if installed properly and adjusted to the manufacturer’s  
specifications. The trailer brakes must meet local and Federal  
regulations.  
WARNING: Do not connect a trailer’s hydraulic brake system  
directly to your vehicle’s brake system. Your vehicle may not  
have enough braking power and your chances of having a collision  
greatly increase.  
The braking system of the tow vehicle is rated for operation at the  
GVWR not GCWR.  
Trailer lamps  
Trailer lamps are required on most towed vehicles. Make sure all running  
lights, brake lights, turn signals and hazard lights are working. Contact  
your authorized dealer or trailer rental agency for proper instructions  
and equipment for hooking up trailer lamps.  
WARNING: Never connect any trailer lighting to the vehicle’s  
taillamp circuits, because it may damage the electrical system  
resulting in fire. Contact your authorized dealer as soon as possible for  
assistance in proper trailer tow wiring installation. Additional electrical  
equipment may be required.

Driving while you tow  
When towing a trailer:  
To ensure proper “break-in” of powertrain components, do not trailer  
tow during the first 1,000 miles (1,600 km) of a new vehicle.  
To ensure proper “break-in” of powertrain components during the first  
500 miles (800 km) of trailer towing, drive no faster than 70 mph  
(113 km/h) with no full throttle starts.  
Turn off the speed control. The speed control may shut off  
automatically when you are towing on long, steep grades.  
Consult your local motor vehicle speed regulations for towing a trailer.  
To eliminate excessive shifting, use a lower gear. This will also assist  
in transmission cooling. For additional information, refer to Automatic  
transmission operation in the Driving chapter.  
Under extreme conditions with large frontal trailers, high outside  
temperatures and highway speeds, the coolant gauge may indicate  
higher than normal coolant temperatures. If this occurs, reduce speed  
until the coolant temperature returns to the normal range. Refer to  
Engine coolant temperature gauge in the Instrument Cluster  
chapter.  
Anticipate stops and brake gradually.  
Do not exceed the GCWR rating or transmission damage may occur.  
Servicing after towing  
If you tow a trailer for long distances, your vehicle will require more  
frequent service intervals. Refer to your scheduled maintenance  
information for more information.  
Trailer towing tips  
Practice turning, stopping and backing up before starting on a trip to  
get the feel of the vehicle trailer combination. When turning, make  
wider turns so the trailer wheels will clear curbs and other obstacles.  
Allow more distance for stopping with a trailer attached.  
If you are driving down a long or steep hill, shift to a lower gear. Do  
not apply the brakes continuously, as they may overheat and become  
less effective.  
The trailer tongue weight should be 10–15% of the loaded trailer  
weight.

If you will be towing a trailer frequently in hot weather, hilly  
conditions, at GCWR, or any combination of these factors, consider  
refilling your rear axle with synthetic gear lube if not already so  
equipped. Refer to the Maintenance and Specifications chapter for  
the lubricant specification. Remember that regardless of the rear axle  
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a  
new vehicle, and that the first 500 miles (800 km) of towing be done  
at no faster than 70 mph (113 km/h) with no full throttle starts.  
After you have traveled 50 miles (80 km), thoroughly check your  
hitch, electrical connections and trailer wheel lug nuts.  
To aid in engine/transmission cooling and A/C efficiency during hot  
weather while stopped in traffic, place the gearshift lever in P (Park).  
Vehicles with trailers should not be parked on a grade. If you must  
park on a grade, place wheel chocks under the trailer’s wheels.  
Launching or retrieving a boat  
Disconnect the wiring to the trailer before backing the trailer  
into the water. Reconnect the wiring to the trailer after the  
trailer is removed from the water.  
When backing down a ramp during boat launching or retrieval:  
do not allow the static water level to rise above the bottom edge of  
the rear bumper.  
do not allow waves to break higher than 6 inches (15 cm) above the  
bottom edge of the rear bumper.  
Exceeding these limits may allow water to enter vehicle components:  
causing internal damage to the components.  
affecting driveability, emissions and reliability.  
Replace the rear axle lubricant any time the axle has been submerged in  
water. Rear axle lubricant quantities are not to be checked or changed  
unless a leak is suspected or repair required.  
RECREATIONAL TOWING  
Follow these guidelines if you have a need for recreational (RV) towing.  
An example of recreational towing would be towing your vehicle behind  
a motorhome. These guidelines are designed to ensure that your  
transmission is not damaged.  
Note: Put your climate control system in recirculated air mode to  
prevent exhaust fumes from entering the vehicle. Refer to the Climate  
controls chapter for more information.
