If a weight-carrying hitch or a weight-distributing hitch
is being used, the trailer tongue (A) should weigh
10-15 percent of the total loaded trailer weight (B).
After loading the trailer, weigh the trailer and then the
tongue, separately, to see if the weights are proper.
If they are not, adjustments might be made by moving
some items around in the trailer.
Total Weight on the Vehicle’s Tires
Be sure the vehicle’s tires are in ated to the upper limit
for cold tires. These numbers can be found on the
Certi cation label or seeLoading the Vehicle on
page 4-20for more information. Make sure not to go
over the GVW limit for the vehicle, or the GAWR,
including the weight of the trailer tongue.
Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads
are a few reasons why the right hitch is needed.
The rear bumper on the vehicle is not intended
for hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a frame-mounted
hitch that does not attach to the bumper.
Will any holes be made in the body of the vehicle
when the trailer hitch is installed? If so, be sure to
seal the holes when the hitch is removed. If they are
not sealed, deadly carbon monoxide (CO) from the
engine’s exhaust can get into the vehicle. See
Engine Exhaust on page 2-34. Sealing the holes will
also prevent dirt and water from entering the vehicle.

Towing a trailer requires a certain amount of experience.
Get to know the rig before setting out for the open road.
Get acquainted with the feel of handling and braking with
the added weight of the trailer. And always keep in mind
that the vehicle you are driving is now longer and not as
responsive as the vehicle is by itself.
Before starting, check all trailer hitch parts and
attachments, safety chains, electrical connectors, lamps,
tires and mirror adjustments. If the trailer has electric
brakes, start the vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure the
brakes are working. This checks the electrical connection
at the same time.
During the trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.Electronic Trailer Sway Control
Electronic Trailer Sway Control is integrated into the
StabiliTrak system of the vehicle. This feature detects
the occurrence of trailer sway that may be caused
by improper trailer weight balance, or excessive vehicle
speed. When the system detects trailer sway, the
StabiliTrak system may begin to apply the front brakes,
without you pressing the brake pedal, to help in
stabilizing the vehicle. The StabiliTrak warning light will
ash to indicate that vehicle speed should be reduced.
If the trailer continues to sway, StabiliTrak will reduce
engine torque as a method to reduce the speed of
the vehicle. Reducing the speed of the vehicle is
necessary to reduce trailer sway. Electronic Trailer
Sway Control is de-activated when StabiliTrak is turned
off, and is re-activated when it is turned back on.
