Do not exceed the maximum
allowable tongue weight for the
vehicle. Choose the shortest hitch
extension that will position the hitch
ball closest to the vehicle. This will
help reduce the effect of trailer
tongue weight on the rear axle.
Trailer rating may be limited by the
vehicle's ability to carry tongue
weight. Tongue or kingpin weight
cannot cause the vehicle to exceed
the GVWR (Gross Vehicle Weight
Rating) or the RGAWR (Rear Gross
Axle Weight Rating). See Total
Weight on the Vehicle's Tires later
in this section.

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.
If a cargo carrier is used in the
trailer hitch receiver, choose a
carrier that positions the load as
close to the vehicle as possible.
Make sure the total weight,
including the carrier, is no more than
half of the maximum allowable
tongue weight for the vehicle or
227 kg (500 lb), whichever is less.

Power Take-Off (PTO)

If equipped, the PTO is an Upfitter
integrated system that is used to
create an auxiliary power source for
running add-on equipment, such as
salt spreaders, snow plows,
winches, and lift buckets. The PTO
system controls engine speed to
values higher than normal base idle,
PTO load relay engagement, and
remote starting and shutdown of the
engine.
When installing PTO aftermarket
equipment, the PTO wiring and
operation recommendations
provided by the service manual and
GM Upfitter documentation must be
strictly followed.
Caution
Engine exhaust contains Carbon
Monoxide (CO), which cannot be
seen or smelled. Exposure to CO
