weight RAM CHASSIS CAB 2007 Owner's Manual

• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. With a manual transmission, shift the
transmission into reverse. And with four-wheel-drive
vehicles, make sure the transfer case is not in neutral.
Always, block or  chock  the trailer wheels.
• GCWR must not be exceeded.
• 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. STARTING AND OPERATING 349

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.
Vehicle front end wheel alignment was set to specifica-
tions at the factory without consideration for the weight
of the plow. Front end tow-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. STARTING AND OPERATING 357

Engine Oil Selection (Gas Engines)
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395. Use Mopar or an equivalent oil meeting the
specification MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacture only recommends
API Certified engine oils. Engine Oil Viscosity (SAE Grade)
For trucks with a 5.7L engine operating under a gross
combined weight rating of 14,000 lbs or greater, SAE
5W-30 engine oil is recommended for all operating
temperatures. For all other trucks with a 5.7L engine,
operating under a gross weight rating less than 14,000
lbs SAE 5W-20 engine oil is recommended for all
operating temperatures. These engine oils improve low
temperature starting and vehicle fuel economy. Your
engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle.
For information on engine oil filler cap location, see the
Engine Compartment illustration in this section.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used. MAINTAINING YOUR VEHICLE 401

Warranty
For 3500 Two-Wheel Drive and Four-Wheel Drive mod-
els over 10,000 lbs. (4 535 kg) Gross Vehicle Weight

Government’s Exterior Noise Regulations. These vehicles
can be identified by the Noise Emission Control Label
located in the operator’s compartment. Required Maintenance For Noise Control Systems
The following maintenance services must be performed
every 6 months or 6,000 miles (9 600 km) whichever
comes first, to assure proper operation of the noise
