1 For towing trailers up to 3500 lb (1588 kg), use a weight-carrying
hitch and ball which uniformly spreads the trailer tongue loads through
the vehicle’s underbody structure. For towing trailers over 3500 lb
(1588 kg), up to 4500 lb (2042 kg), it is recommended to use a
weight-distributing hitch to increase front axle load while towing.
2 For towing trailers up to 4500 lb (2042 kg), use a weight-carrying
hitch and ball which uniformly spreads the trailer tongue loads through
the vehicle’s underbody structure.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.
Hitches
Do not use a hitch that clamps onto the vehicle’s 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.
Weight-distributing hitch
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park the vehicle (without the trailer) on a level surface.
2. Measure the height of the top of the front wheel opening on the
fender, this is H1.
