ing brake on the tow vehicle. Put the tow
vehicle transmission in PARK. For four-
wheel drive vehicles, make sure the trans-
fer case is not in NEUTRAL. Always, block
or "chock" the trailer wheels.
• GCWR must not be exceeded.

tween the tow vehicle and the trailer
such that the following four ratings are

Towing Requirements – Tires
• Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle. Refer to "Tires – General Informa-
tion" in "Starting and Operating" for proper
tire inflation procedures.
• Check the trailer tires for proper tire inflation
pressures 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 proper inspection procedure.
• When replacing tires, refer to "Tires – Gen-
eral Information" in "Starting and Operating"
for proper tire replacement procedures. Re-
placing tires with a higher load carrying ca-
pacity will not increase the vehicle's GVWR
and GAWR limits.
Towing Requirements – Trailer Brakes
• Do not interconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury.
• An electronically-actuated trailer brake con-
troller 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.
• Trailer brakes are recommended for trailers
over 1,000 lbs (454 kg), and required for
trailers in excess of 1,654 lbs (750 kg).
WARNING!
• Do not connect trailer brakes to your vehi-
cle's hydraulic brake lines. It can overload
your brake system and cause it to fail. You
might not have brakes when you need
them and could have an accident.
• Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and
the vehicle in front of you. Failure to do so
could result in an accident.
