load capacity Ram 2500 (Diesel) 2007 User Guide

•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. 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 the
Tires–General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
Also, 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 the Tires–General
Information section of this manual on Tread Wear
Indicators for the proper inspection procedure.
When replacing tires refer to the Tires–General Infor-
mation section of this manual on Replacement Tires for
proper tire replacement procedures. Replacing tires
with a higher load carrying capacity will not increase
the vehicle’s GVWR and GAWR limits.
366 STARTING AND OPERATING

Towing Requirements — Trailer Brakes

Donotinterconnect 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.

Before plowing
•
Check the hydraulic system for leaks and proper fluid
level.
•Check the mounting bolts and nuts for proper tight-
ness.
•Check the runners and cutting edge for excessive wear.
The cutting edge should be 1/4 to 1/2 inch above
ground in snow plowing position.
•Check that snowplow lighting is connected and func-
tioning properly.
Snowplow Prep Package Model Availability
For Information about snowplow applications visit
www.dodge.com or refer to the current Dodge Body
Builders Guide.
1. The maximum number of occupants in the truck
should not exceed two.2. The total GVWR or the Front GAWR or the Rear
GAWR should never be exceeded.
3. The snowplow prep packages are not available with
the Sport Package.
4. 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.
