2. GTW

4. Trailer tongue weight rating for the trailer hitch
utilized (This requirement may limit the ability to
always achieve the 10% to 15% range of tongue
weight as a percentage of total trailer weight).
Towing Requirements – Tires
•
Do not attempt to tow a trailer while using a compact
spare tire.
•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 proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
•
Donot 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.
•Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’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 a
collision.
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
Integrated Trailer Brake Module – If Equipped
Your vehicle may have a Integrated Trailer Brake Module
for electric trailer brakes.

2. The total GVWR or the Front GAWR or the Rear
GAWR should never be exceeded.
3. Cargo capacity will be reduced by the addition of
options or passengers, etc.
The loaded vehicle weight, including the snowplow
system, all aftermarket accessories, driver, passengers,
options, and cargo, must not exceed either the Gross
Vehicle Weight (GVWR) or Gross Axle Weight (GAWR)
ratings. These weights are specified on the Safety Com-
pliance Certification Label on the driver’s side door
opening.
NOTE:Detach the snowplow when transporting pas-
sengers.
Vehicle front end wheel alignment was set to specifica-
tions at the factory without consideration for the weight
of the plow. Front end toe-in should be checked and reset if necessary at the beginning and end of the snowplow
season. This will help prevent uneven tire wear.
The blade should be lowered whenever the vehicle is
parked.
Maintain and operate your vehicle and snowplow equip-
ment following the recommendations provided by the
specific snowplow manufacturer.
Over The Road Operation With Snowplow
Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
