Maximum Front and Rear Axle
Weights
The weight of the cargo load must
be properly distributed over both the
front and rear axles. The “VIN,Weight Rating, and Greenhouse
Gas (GHG) Emissions Plate”
shows
the maximum weight that the front
axle can carry (front GAWR). It also
shows the maximum weight that the
rear axle can carry (rear GAWR).
The GVWR is the maximum
permissible loaded weight of the
vehicle and takes into account the
capabilities of the engine,
transmission, frame, springs,
brakes, axles and tires. Actual loads
at the front and the rear axles can
only be determined by weighing the
vehicle. This can be done at
highway weigh stations or other
such places. See your dealer for help. The cargo load should be
distributed on both sides of the
center line as equally as possible.
Tires
The tires on your truck must be of
the proper size and properly inflated
for the load that you are carrying.
The
“VIN, Weight Rating, and
Greenhouse Gas (GHG) Emissions
Plate” shows the originally equipped
tire size and recommended inflation
pressures.
For the vehicle plate location, see
Vehicle Identification Number (VIN)
0 330.
See “Tire Load and Inflation Table”
under Tire Pressure 0284.

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.
For safety reasons, do not place
packages, tools, or other items in
the driver ’s area that may restrict
access to the controls or sight of the
gauges.

booster (HBB) becomes faulty. The
warning buzzer will stop sounding
when the parking brake is engaged.
On 4500HD and 4500XD, the brake
low vacuum warning light and
warning buzzer should come on to
indicate low vacuum reserve for
brake power assist. At the same
time, the Back up Electric Vacuum
Pump operates.

reserve is greatly reduced each
time you apply and release the
brakes.

longer. .
You may have to push much
harder on the brake pedal.
. Have the vehicle repaired before
you continue driving.
The buzzer stops when the selector
lever is shifted to the P position.

sounds as the brakes are not
operating to their full capacity.

injured.

This light comes on briefly when the
engine control switch is turned to
the ON position, and then should go

come on, have it fixed so it will be
ready to warn if there is a problem.

together with the brake system
warning light whenever there is a
problem in the Anti-lock Brake
System (ABS). In this case, the ABS
stops working but the brakes still
function as ordinary service brakes.

while driving, immediately stop
your vehicle at a safe place well
clear of traffic and take the
following actions.
1. Stop the engine.
2. Restart the engine. Check ifthe ABS warning light
comes on and then goes
out. If it does, there is no
problem. The ABS operates
normally.
