Using a load-equalizing hitch
When hooking up a trailer using a
load-equalizing hitch, always use
the following procedure.
1. Park the unloaded vehicle on a
level surface. With the ignition on
and all doors closed, allow the
vehicle to stand for several
minutes so that it can level.
2. Turn the air suspension switch
to OFF (if equipped).
3. Measure the height of a
reference point on the front and
rear bumpers at the center of the
vehicle.
4. Attach the trailer to the vehicle
and adjust the hitch equalizers so
that the front bumper height is
0–13 mm (0.5 in). After proper
adjustment, the rear bumper
should be no higher than in step 3.
5. Turn on the air suspension
switch.
Adjusting an equalizing
hitch so the rear bumper
of the vehicle is lower or higher
than it was unloaded will defeat
the function of the load
equalizing hitch and may cause
unpredictable handling.
Step bumper (if equipped)
Step bumpers have a built-in hitch
and only require a ball with a 2.5
cm (1 in.) shank diameter. Step
bumpers have a Class III capability
(2,270 kg [5,000 lb] trailer weight
and 91 kg [200 lb] tongue weight.
