*-When towing maximum loads under high outside temperatures and
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.
