Connecting Trailer Lights
Connect the trailer lights to the tow vehicle’s electrical system using the electric connectors at the front of the trailer (tongue). Refer to the wiring diagram shown in the trailer wiring diagram section of this manual. Before towing the trailer check for the following:
Running lights (turn on tow vehicle headlights).
Brake Lights (step on tow vehicle brake pedal).
Backup Lights (place tow vehicle gear shift in reverse).
Turn Signals (activate tow vehicle directional signal lever).
WARNING - Improper Electrical Connections
Improper electrical connection between the tow vehicle and the trailer will result in inoperable lights and electric brakes, and can lead to collision.
Before each tow:
Check that the taillights, brake lights and turn signals work
Check that the electric brakes work by operating the brake controller inside the tow vehicle.
Uncoupling the Ball Hitch
Follow these steps to uncouple ball hitch from tow vehicle:
Block trailer tires to prevent the trailer from rolling, before jacking the trailer up.
Disconnect the electrical connector.
Disconnect the breakaway brake switch cable. Promptly replace the pullpin in the switchbox.
Before extending jackstand, make certain the ground surface below the jackstand foot will support the tongue load.
Rotate the jackstand handle (or crank) clockwise. This will slowly extend the jack and transfer the weight of the trailer tongue to the jack.
TIRE SAFETY
Unsafe Tires, Lug Nuts or Wheels
Trailer tires and wheels are more likely to fail than car tires and wheels because they carry a heavier load. Therefore, it is essential to inspect the trailer tires before each tow.
If a tire has a bald spot, bulge, cuts, is showing any cords, or is cracked, replace the tire before towing. If a tire has uneven tread wear, take the trailer to a dealer service center for diagnosis.
Uneven tread wear can be caused by tire imbalance, axle misalignment or incorrect inflation.
Tires with too little tread will not provide adequate tracking on wet roadways and can result in loss of control, leading to death or serious injury.
Improper tire pressure causes an unstable trailer and can result in a tire blowout and loss of control. Therefore, before each tow you must also check the tire pressure. Tire pressure must be checked when tires are cold.
Allow 3 hours
Since trailer wheels and lug nuts (or bolts) are subjected to greater side loads than automobile wheels, they are more prone to loosen. Before each tow, check to make sure they are tight.
The proper tightness (torque) for lug nuts is listed in the lug nut tightening section of this manual. Use a torque wrench to tighten the lug nuts. If you do not have a torque wrench, use a lug wrench (from your tow vehicle) and tighten the nuts as much as you can. Then have a service garage or trailer dealer tighten the lug nuts to the proper torque.
WARNING - Lug Nut Tightening
Metal creep between the wheel rim and lug nuts will cause rim to loosen and could result in a wheel coming off, leading to death or serious injury.
Tighten lug nuts before each tow.
