Do not use a bumper-mounted trailer hitch 
Never install a trailer hitch on the bumper or on the bumper attachments. The trailer hitch must not interfere with the impact-absorbing bumper system. Do not make any changes to the vehicle exhaust and brake systems. From time to time, check that all trailer hitch mounting bolts are securely fastened. When you are not towing, remove the trailer hitch. This helps keep the trailer hitch from causing dam-age if your vehicle is hit from behind. 
Engine cooling system 
Towing a trailer makes the engine and its cooling system work harder. It is important that the engine cooling system is up to the job. Make sure that the cooling system has enough coolant. 
Trailer brakes 
If your trailer has its own brakes, make sure it meets all regulations. The trailer brake system must never be directly connected to the vehicle's brake system. 
Safety chains 
Always use safety chains between your vehicle and the trailer ⇒ Hitching up and connecting a trailer. 
Trailer taillights 
Trailer lights must meet all regulations ⇒ Hitching up and connecting a trailer. 
Never connect the trailer lights directly to the electrical system of your vehicle. 
Outside mirrors 
If you cannot see the traffic behind you using the regular outside mirrors, then you must install extend-ed mirrors. Extended mirrors may also be required by law in some countries/states/provinces. Always adjust the outside mirrors before driving. It's vital that you always have a clear view to the rear of the vehicle. 
Maximum power consumption for the trailer 
Do not exceed the power ratings listed in the chart below. 
 
Electrical load   Maximum power  
Brake lights total   108 watts  
Turn signals per side   54 watts  
Side marker lights total   100 watts  
Taillights total  54 watts  
 
  WARNING 
 x An improperly installed or incorrect trailer hitch can cause a trailer to separate from the tow vehicle and cause serious personal injuries. 
 x If you don't have to tow a trailer any more, remove the entire trailer hitch. Always seal all bolt holes to prevent water and deadly exhaust fumes from getting into the vehicle.
