Calculating the Maximum Loaded
Trailer Weight for Your Vehicle
1. Start with the gross combined weight
rating for your vehicle model and axle
ratio. See the following chart.
2. Subtract all of the following that apply
to your vehicle:
• Vehicle curb weight
• Hitch hardware weight, such as a draw
bar, ball, locks or weight distributing
hardware
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage weight
• Aftermarket equipment weight.
This equals the maximum loaded trailer
weight for this combination.
Note: The trailer tongue load is considered
part of the payload for your vehicle. Reduce
the total payload by the final trailer tongue
weight.
Note: Consult an authorized dealer to
determine the maximum trailer weight
allowed for your vehicle if you are not sure.

ESSENTIAL TOWING CHECKS

Follow these guidelines for safe towing:
• Do not tow a trailer until you drive your
vehicle at least 1000 miles (1600
kilometers).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See your scheduled
maintenance information.
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
