Towing a Trailer
Trailer Lights
Trailer lights and equipment must
comply with federal, state, provincial,
territorial, and local regulations.
Check with your local trailer dealer
or rental agency for the
requirements in the area where you
plan to tow, and use only equipment
designed for your vehicle.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualified technician install a
suitable connector between the
vehicle and the trailer. Improper
equipment or installation can cause
damage to your vehicle's electrical
system and affect your vehicle
warranty.

Additional Towing Equipment
Many states and Canadian
provinces/territories require special
outside mirrors when towing a trailer.
Even if they don't, you should install
special mirrors if you cannot clearly
see behind you, or if the trailer
creates a blind spot.
I n f o r ma t i o n P r o v i d e d b y :
Ask your trailer sales or rental
agency if any other items are
recommended or required for your
towing situation.
