GENERAL TRAILERING INFORMATION
Driving a vehicle with a trailer in tow is vastly different from driving the same
vehicle without a trailer in tow. It takes longer to get up to speed. You need
more room to turn and pass, and more distance to stop when towing a trailer.
You are responsible for keeping your vehicle and trailer in control, and for all
damage that is caused if you lose control of your vehicle and trailer.
It is critical that the trailer be securely coupled to the hitch and that the safety
chains are correctly attached. Uncoupling while towing may result in death or
serious injury.
If the trailer comes loose from the hitch for any reason, we have provided safety
chains so that control of the trailer can be maintained.
Your trailer is equipped with a breakaway brake system that will apply the brakes
on your trailer if your trailer comes loose from the hitch. The safety chains and
breakaway brake system must be in good condition and properly rigged to be
effective. The breakaway brake system must not be used as a substitute for a
parking brake or wheel chocking.
Be sure your hitch and tow vehicle are rated for the Gross Vehicle Weight Rating
(GVWR) of your trailer.
Maximum towing speed 45 mph.
Be sure tires are inflated to pressure indicated on tire size and air pressure ID tag
before towing. Improper inflation can result in a blowout and loss of control,
which can lead to death or serious injury.
Be sure lug nuts are tight before each tow.
Be sure that the electric brakes and all of the lights on your trailer are functioning
properly before each tow.
Altering your trailer can damage essential safety items. DO NOT alter your
trailer.

SAFE TRAILER TOWING GUIDELINES
Before towing, check coupling, safety chains, safety brake, tires, wheels and
lights.
Check the breakaway battery. Make sure it is fully charged.
Check the wheel lug nuts or bolts for tightness. 85-95 ft. /lbs.
Check coupler tightness after towing 50 miles (80km).
Adjust the brake controller to engage the trailer brakes before the tow vehicle
brakes.
Use your mirrors to verify that you have enough room to change lanes or pull into
traffic.
Use your turn signals well in advance.
Allow plenty of stopping distance for your trailer and tow vehicle.
Do not drive faster than the conditions will allow.
Allow plenty of room for passing. A rule of thumb is that passing distance with a
trailer is 4 times the passing distance without a trailer.
Use lower gears for climbing and descending grades.
Do not ride the brakes while descending grades; this can cause overheating and
potential brake failure.
Slow down for bumps in the road. Take your foot off the brake pedal when
crossing the bump.
Slow down prior to entering a curve; maintain a constant safe speed that allows
you to remain in control of your trailer. The towing vehicle will then remain in
control of the trailer.
Do not apply the tow vehicle brakes to correct extreme trailer swaying.
Continued pulling of the trailer, and even slight acceleration, or carefully applying
the trailer brakes (using the electronic brake controller) will provide a stabilizing
force.

SAFE TRAILER TOWING GUIDELINES –(continued)
Make regular stops to confirm
The coupler is secure to the hitch and is locked.
Electrical connections are made.
There is appropriate slack in the safety chains.
There is appropriate slack in the breakaway switch pull-pin cable.
The tires are inflated to proper air pressure and no damage or unusual wear to
tread or sidewalls.
The trailer and doors are secure, latched and in good condition.
Wheel chock user guidelines
Improper use may result in product failure.
Select wheel chock according to the equipment type and size.
Always use in pairs and on firm surfaces.
Chock in direction of grade.
Chock both sides of wheel if direction of grade is undetermined.
Use only after parking brake is applied and tested.
Center chocks snugly and squarely against tread of each wheel.
Always test chocks to insure they meet requirements.
Do not drive over wheel chocks.
