# If your vehicle is equipped with a code 5 engine
you must use regular unleaded gasoline rated at
87 octane or higher when towing.
Optional body styles, equipment, passengers or cargo
will reduce trailer rating.
Maximum trailer weight is calculated assuming the
driver and one passenger are 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" later in this section.
You can ask your dealer for our trailering information or
advice, or you can write us at the address listed in your
Warranty and Owner Assistance Information Booklet.
