Trailer towing table
If your vehicle exceeds the GVWR, remove cargo from your vehicle
accordingly. If your vehicle exceeds either GAWR, shift the
load or remove cargo accordingly.
To determine actual GCW, weigh the total vehicle and trailer and
also weigh the trailer separately to verify its weight.
Trailers
Towing a trailer safely means having the proper weight on the
tongue (usually 10-15% of the trailer weight).
Do not exceed the GVWR or the GAWR specified on the
Safety Compliance Certification Label.
Towing trailers beyond the maximum recommended gross
trailer weight exceeds the limit of the vehicle and could
result in engine damage, transaxle damage, structural
damage, loss of control, and personal injury.
