ECU DODGE RAM 1500 GAS 2004 3.G Owner's Manual

Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Also overloading can
shorten the life of your vehicle.
An EXAMPLE of a loaded vehicle is shown in the
following chart. Note that neither GVWR nor GAWR
capabilities are exceeded. Overloading can cause poten-
tial safety hazards and shorten service life.

²Be sure the trailer is loaded heavier in front, with 60%
to 65% of the weight in front of the axle(s). Loads
balanced over the wheels or heavier in the rear can
cause the trailer to sway severely side to side which
will cause loss of control of vehicle and trailer. Failure
to load trailers heavier in front is the cause of many
trailer accidents. (For a95th Wheel9style trailer, this
range of loading on the9King Pin9should be between
15% and 25%.)
²Make certain that the load is secured in the trailer and
will not shift during travel. When towing cargo such
as livestock, dynamic load shifts can occur that require
the driver to maintain attention.
Trailer Towing Ð Hitches
With a Class I Hitch, your vehicle can be equipped to tow
trailers with a Gross Trailer Weight (GTW) of 2,000 lbs
(907 kg) maximum.With a Class II Hitch, your vehicle can be equipped to
tow trailers with a Gross Trailer Weight (GTW) of 3,500
lbs (1 587 kg ) maximum. Tongue weight must be equal to
at least 10% of GTW, but no more than 15% of GTW.
With a Class III Hitch, your vehicle can be equipped to
tow trailers with a Gross Trailer Weight (GTW) of 5,000
lbs (2 268 kg) maximum. Factory-installed rear step
bumpers are rated a Class III hitch.
A frame mounted hitch of up to Class IV rating, as rated
by the hitch manufacturer, may also be installed. With a
Class IV Hitch, you can tow a trailer with a Gross Trailer
Weight of up to 12,000 lbs (5 443 kg) maximum depend-
ing on your vehicle equipment.

300 WHAT TO DO IN EMERGENCIES

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
Brake System
Power Disc Brakes (front and rear)
Disc brakes do not require adjustment; however, several
hard stops during the break-in period are recommended
to seat the linings and wear off any foreign material.
Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the brake system warning lamp indicates system
failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
ªMAXº dot and an ªMINº dot. The fluid level must be
kept within these two dots. Do not add fluid above the
MAX mark, because leakage may occur at the cap.
With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to Recommended Fluids, Lubricants and Genuine
Parts for the correct Fluid type.
