the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.

Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.

under the bumper. This connector contains the follow-
ing vehicle circuits: park/tail lamps, left stop/turn
lamp, right stop/turn lamp, and ground. With the
optional Trailer Tow Prep package a 7-way connector
is provided with the following additional circuits:
backup lamp, trailer battery and electric brake.
NOTE:Connect trailer lighting and brakes using factory
harnesses only. Do not cut or splice wiring to the brake
circuits.
•Be sure the trailer is loaded heavier in front, with 60%
to 65% of the weight in front of the axle(s). Loads
balanced over the wheels or heavier in the rear can
cause the trailer to sway severely side to side which
will cause loss of control of vehicle and trailer. Failure
to load trailers heavier in front is the cause of many
trailer accidents. (For a5th Wheelstyle trailer, this
range of loading on theKing Pinshould be between
15% and 25%.)
•Make certain that the load is secured in the trailer and
will not shift during travel. When towing cargo such
as livestock, dynamic load shifts can occur that require
the driver to maintain attention.
Trailer Towing — Hitches
With a Class I Hitch, your vehicle can be equipped to tow
trailers with a Gross Trailer Weight (GTW) of 2,000 lbs
(907 kg) maximum.

With a Class III Hitch, your vehicle can be equipped to
tow trailers with a Gross Trailer Weight (GTW) of 5,000
lbs (2 268 kg) maximum. Factory-installed rear step
bumpers are rated a Class III hitch. Tongue weight must
be equal to at least 10% of the gross trailer weight (GTW),
but no more than 15% of the GTW.
