DRIVING
Any additional weight, cargo, or accessories reduce the maximum trailer
weight and maximum tongue load.
Tongue Load
The weight of the tongue with a fully loaded trailer on the hitch should be
approximately:
• Boat trailers: 5 - 15% of the total
trailer weight
• Other trailers: 10 - 15% of the total
trailer weight
To estimate the tongue load
Excessive tongue load reduces front tire traction and steering control. Too
little tongue load can make the trailer unstable and cause it to sway.
You can estimate the tongue load by measuring the trailer hitch height from
the ground in the following steps:
1. Park the vehicle on level ground.
2. Measure the distance between the ground and the bottom of the trailer
hitch.
3. Connect the fully loaded trailer to the hitch.
4. Measure the distance between the ground and the bottom of the trailer
hitch again.
5. Subtract the second measurement from the first measurement, then
refer to the following table.
100 |
If the difference becomes more than indicated in the table, distribute the
load or remove cargo as needed.
How to weigh the trailer loads using a public scale
Check each weight in the order indicated as shown. Refer to the table
below for each weight's limit except for the tongue load.
• If you cannot weigh the rear axle, subtract 1 from 2.
• The maximum gross combined weight (4) decreases by 2% for every 1,000
feet (305m) of elevation.
• To calculate the tongue load, subtract 5 from 6.
• Refer to the trailer owner's manual for additional information.
Fully load the vehicle and trailer. An attendant who watches the scale is
needed as all occupants should stay in the vehicle.
If a public scale is not available, add the estimated weight of your cargo
load to the weight of your trailer (as quoted by the manufacturer), and then
measure the tongue load with an appropriate scale or tongue gauge or
estimate it based on cargo distribution.
Pre-tow Checklist
When preparing to tow, and before driving away, ensure the following:
• The vehicle has been properly serviced, and the suspension and the
cooling system are in good operating condition.
• Avoid towing a trailer during your vehicle's first 600 miles (1,000 km).
• The trailer has been properly serviced and is in good condition.
• All weights and loads are within limits. Never exceed the gross weight
ratings.
• Check if all loads are within limits at a public scale.
• The hitch, safety chains, and any other attachments are secure.
