Pre-Tow Checklist
When preparing to tow, and before driving away, be sure to check the following:
• Avoid towing a trailer during your vehicle’s first 600 miles (1,000 km).
• The vehicle and trailer have been properly serviced and are in good condition.
Lights and brakes work properly, and the tires are properly inflated.
• All weights and loads are within limits. Never exceed the gross weight ratings.
• When towing more than 3,500 lbs (1,590 kg), use of gasoline with an octane
rating of 91 or higher is recommended.
• Check if all loads are within limits at a public scale (see page 90). If a public
scale is not available, add the estimated weight of your cargo load to the
weight of the trailer (as quoted by the manufacturer) and the tongue load.
• The hitch, safety chains, and any other attachments are secure.
• All items in or on the trailer are properly secured and cannot shift while you
drive.
Exceeding any load limit or improperly loading your vehicle and trailer can
cause a crash in which you can be seriously hurt or killed.
Check the loading of your vehicle and trailer carefully before starting to
drive.
