Safety chains
Always connect the trailer’s safety chains to hook retainers on the
vehicle. To connect the trailer’s safety chains, cross the chains under the
trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric, manual, automatic or surge-type brakes, if compatible with the
vehicle, are safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
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.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Do not
connect trailer lamps directly to your vehicle’s tail lamps. This can cause
damage to your vehicle’s electrical system. See your authorized dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Driving while you tow
When towing a trailer:
•
Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
•
Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•
Consult your local motor vehicle speed regulations for towing a trailer.
