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.
*-When towing maximum loads under high outside temperatures and/or on
steep grades, the A/C system may cycle on and off to protect the engine
from overheating. This may result in a temporary increase of interior
temperatures.
Towing a trailer over 1588 kg (3500 lbs.) requires a weight distributing
hitch.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
