Your vehicle was primarily designed to carry passengers and cargo. It is important to remember that towing a trailer will place additional loads on your vehicle's engine, drive train, steering, braking and other systems. However, if you find it necessary to tow a trailer, using the proper equipment is a must.
Local laws may require specific equipment such as trailer brakes or fender mounted mirrors. Check with your local authorities.
The trailer hitch assembly should conform to all applicable laws and be sufficient for the maximum trailer load.
Almost all trailers now come equipped with rear and side lighting. A wiring harness must be installed to connect the automotive lighting and brake light systems to the trailer. Any reputable hitch installer can perform this installation. You can also install the harnesses, but great care must be paid to matching the correct wires during the installation. Each circuit must be wired individually for taillights, brake lights, right and left turn signals and in many cases, reverse lights. If the trailer is equipped with electric brakes, the wiring for this circuit should be installed at the same time as the lighting harness. Remember that the additional lighting may exceed the present fuse rating in the car's fusebox; an upgrade may be necessary.
