Driving
■Trailer light
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.
We recommend that you have a dealer inst all a Acura wiring harness and converter.
They are designed for your vehicle.
■Hitches
Read the trailer manufacturer ’s instructions, and select the appropriate draw bar for
the height of the trailer you will be towing.
■Weight distribution hitches
Your vehicle is designed to tow without the need for a load distributing hitch. If you
wish to use one, please cons ult your trailer maker for proper installation and set-up.
Improper set-up could degrade the handling, stability, and braking performance of
your vehicle.
