towing package
•Not to exceed 60 square feet (5.52 square meters) with Class IV
trailer towing package
Note:Do not exceed trailer weight of 5,000 lb (2268 kg) when towing

Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle’s bumper or attach to the
axle. You must distribute the load in your trailer so that 10%–15% of the
total weight of the trailer is on the tongue.
