Trailer lights and equipment must comply with federal, state, province/territory, and
local regulations. Check with your local trailer sales or rental agency for the
requirements in the area where you plan to tow.

Driving
The 7-pin trailer connector is needed for your trailer lights. When inserting the
connector to the socket, check if the co nnector and the socket are free of dirt,
moisture, or other foreign material.
The lighting and wiring of trailers can vary by type and brand. If a connector is
required, it should only be installed by a qualified technician.
■Sway control
This device can be used if your trailer te nds to sway. Your trailer maker can tell you
what kind of sway control you need and how to install it. Improper installation could
degrade the handling and stability of your vehicle.
■Trailer mirrors
Many states, provinces and territories requir e special exterior mirrors when towing a
trailer. Install special mirrors whenever you cannot clearly see behind you, or if the
trailer creates a blind spot.
