Towing Requirements – Tires
− Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
"Tires – General Information" in "Starting and Oper-
ating" for proper tire inflation procedures.
− Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
− Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to "Tires – General
Information" in "Starting and Operating" for the
proper inspection procedure.
− When replacing tires, refer to "Tires – General Infor-
mation" in "Starting and Operating" for information
on replacement tires and for proper tire replacement
procedures. Replacing tires with a higher load carry-
ing capacity will not increase the vehicle's GVWR and
GAWR limits.
Towing Requirements – Trailer Brakes
− Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
− An electronically-actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge-actuated brake system, an electronic
brake controller is not required.
