Safety chains
You should always attach chains between your vehicle and your trailer. Cross the safety
chains under the tongue of the trailer so that the tongue will not drop to the road if it
becomes separated from the hitch.
Instructions about safety chains may be provided by the hitch manufacturer or by the
trailer manufacturer. Follow the manufacturer's recommendation for attaching safety
chains. Always leave just enough slack so you can turn with your trailer. Never allow safety
chains to drag on the ground.
Trailer brakes
If your trailer is equipped with a braking system, make sure it conforms to the country's
regulations, and that it is properly installed and it is operating correctly.
If your trailer weighs more than the maximum trailer weight without trailer brakes loaded,
then it needs its own brakes, and those trailer brakes must be adequate. Be sure to read
and follow the instructions for the trailer brakes so that you will be able to install, adjust,
and maintain them properly.
僅 Do not tap into your vehicle's brake system.
WARNING
Do not use a trailer with its own brakes unless you are absolutely certain that you have
properly set up the brake system. This is not a task for amateurs. Use an experienced,
competent trailer shop for this work.
Driving with a trailer
Towing a trailer requires a certain amount of experience. Before setting out for the open
road, you must get to know your trailer. Acquaint yourself with the feel of handling and
braking with the added weight of the trailer. Always keep in mind that the vehicle you are
driving is now a lot longer and not nearly as responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains, electrical connector(s),
lights, tires, and mirror adjustment. If the trailer has electric brakes, start your vehicle and
trailer moving, and then apply the trailer brake controller by hand to make sure the brakes
are working. This lets you check your electrical connection at the same time.
During your trip, check occasionally to make sure that the load is secure and that the
lights and trailer brakes are still working.
NOTE
When the ambient temperature is lower than 0°C (32°F) and the remaining high voltage
battery is low, the power of the vehicle with a trailer can be dropped, causing a trouble in
acceleration or drop of the speed when driving hills.
When driving with a trailer, be sure to charge the high voltage battery more than 50% if
the ambient temperature is lower than 0°C (32°F).
Following distance
Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle
without a trailer. This can help you avoid situations that require heavy braking and sudden
turns.
