WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.

Temperature conditions can also affect
towing. For example, towing a heavy trailer
in high outside temperatures on graded
roads can affect engine performance and
cause overheating. The engine protection
mode, which helps reduce the chance of
engine damage, could activate and auto-
matically decrease engine power. Vehicle
speed may decrease under high load. Plan
your trip carefully to account for trailer and
vehicle load, weather and road conditions.

Also weigh the front and rear axles on the
scale to make sure the Front Gross Axle
Weight and Rear Gross Axle Weight are not
more than Front Gross Axle Weight and
Rear Gross Axle Weight on the
F.M.V.S.S./C.M.V.S.S. certification label. The
cargo in the trailer and vehicle may need to
be moved or removed to meet the speci-
fied ratings.
Example:∙ Gross Vehicle Weight (GVW) as weighed on a scale - including passengers, cargo
and hitch - 6,350 lbs. (2,880 kg).
∙ Gross Vehicle Weight Rating (GVWR) from F.M.V.S.S./C.M.V.S.S. certification la-
bel - 7,250 lbs. (3,289 kg).
∙ Gross Combined Weight Rating (GCWR) from “Towing Load/Specification" chart
- 15,100 lbs. (6,849 kg).
∙ Maximum Trailer towing capacity from “Towing Load/Specification" chart -
9,100 lbs. (4,128 kg).

WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than the
weight rating of the hitch components.
Never exceed the weight rating of the
hitch components. Doing so can cause se-
rious personal injury or property damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:∙ The required hitch ball size is stamped on most trailer couplers. Most hitch
balls also have the size printed on the
top of the ball.
∙ Choose the proper class hitch ball based on the trailer weight.
∙ The diameter of the threaded shank of the hitch ball must be matched to the
ball mount hole diameter. The hitch ball
shank should be no more than 1/16”
smaller than the hole in the ball mount.
∙ The threaded shank of the hitch ball must be long enough to be properly
secured to the ball mount. There should
be at least 2 threads showing beyond
the lock washer and nut.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the
hitch receiver. Choose a proper class ball
mount based on the trailer weight. Addi-
tionally, the ball mount should be chosen to
keep the trailer tongue level with the
ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on
the receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer
to distribute the tongue weight (hitch
weight) of your trailer. Many vehicles can’t
carry the full tongue weight of a given
trailer, and need some of the tongue
weight transferred through the frame and
pushing down on the front wheels. This
gives stability to the tow vehicle. A weight-distributing hitch system (Class
IV) is recommended if you plan to tow trail-
ers with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge
brakes. If you are considering use of a
weight-distributing hitch system with a
surge brake-equipped trailer, check with
the surge brake, hitch or trailer manufac-
turer to determine if and how this can be
done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level sur- face. With the ignition on and the doors
closed, allow the vehicle to stand for
several minutes so that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle.

3. Attach the trailer to the vehicle and ad-just the hitch equalizers so that the
front bumper height is within 0 -
.5 inches (0 – 13 mm) of the reference
height measured in step 2. The rear
bumper should be no higher than the
reference height measured in step 2.

∙ To reduce the possibility of additionaldamage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
∙ Regularly check that all trailer hitch mounting bolts are securely
mounted.
Tire pressures
∙ When towing a trailer, inflate the
vehicle tires to the recom-
mended cold tire pressure indi-
cated on the Tire and Loading In-
formation label.
∙ Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer’s
specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety
chains should be crossed and should be
attached to the hitch, not to the vehicle
bumper or axle. The safety chains can be
attached to the bumper if the hitch ball is mounted to the bumper. Be sure to leave
enough slack in the chains to permit turn-
ing corners.
