Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are safe if installed properly and adjusted to the manufacturer’s specifications. The trailer brakes must meet local and Federal regulations.
WARNING: Do not connect a trailer’s hydraulic brake system directly to your vehicle’s brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase.
WARNING: Do not operate Adaptive Cruise Control (ACC) when towing a trailer equipped with brakes. Aftermarket trailer brakes will not function properly when ACC is activated, which may lead to loss of vehicle control, increasing the risk of serious injury.
The braking system of the tow vehicle is rated for operation at the GVWR not GCWR.
