Maximum frontal area of trailer is 3.72 square meters (40 square feet).
Notes: For high altitude operation, reduce GCW by 2% per 300 meters
(1000 ft) elevation. For definitions of terms used in this table and
instructions on how to calculate your vehicle load, refer to Vehicle
loading in this chapter. Maximum trailer weights shown. The
combined weight of the completed towing vehicle and the loaded
trailer must not exceed the GCWR.
In ambient temperatures greater than 38°C (100°F), it is recommended
that the maximum GCW be reduced to 5262 kg (11600 lbs). At these
temperatures, vehicle speed should be kept below 97 km/h (60 mph)
during highway operation. Extended operation above 4000 rpm should
be avoided.
Towing a trailer over 1588 kg (3500 lbs.) requires a weight distributing
hitch.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
