Sport Appearance Package), your vehicle was
neither intended nor designed to tow a trailer. For more
information on RPO codes, see Service Parts

Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
The weight of the trailer tongue also affects trailering
capacity. See " Weight of the Trailer Tongue " next.
