NOTE
For Export vehicles, the fuel gauges
will not state: ULTRA LOW SULFUR
DIESEL FUEL ONLY.
NOTE
This vehicle may be manufactured
with different fuel systems and differ-
ent draw tube locations. Because of
this and the amount of road crown, it is
recommended that you do not operate
your vehicle with less than one-quarter
of your truck’s fuel capacity. Allowing
the fuel level to go below one-quarter
of capacity could result in the lack of
fuel to keep the engine running. In ad-
dition, you will want to keep the fuel
tanks at least half-full to reduce con-
densation of moisture in the tanks.
This moisture can damage the engine.

Engine, Oil Pressure
If oil pressure drops below the minimum
psi a red warning light in the gauge will turn
on, the Stop Engine light will come on and
an audible alarm tone will sound.
CAUTION
Continuing to operate your vehicle with
insufficient oil pressure will cause seri-
ous engine damage. Failure to comply
may result in equipment or property
damage.
It is important to maintain oil pressure
within acceptable limits. For further
information on engine oil and normal
operating pressures, see the Engine
Operation and Maintenance Manual. If the
oil pressure fails to rise within 10 seconds
after the engine starts, stop the engine and
determine the cause. Check the engine
manufacturer's manual for the correct oil
pressure ranges for your vehicle's engine.
If the oil pressure suddenly drops, or the
audible alarm and engine oil pressure
warning light come on while driving. For
further information on engine gauges and
operating your engine properly, refer to
Engine Maintenance material.
Diesel Exhaust Fluid (DEF)
The diesel exhaust fluid gauge shows the
approximate amount of DEF fluid in the
DEF tank.
CAUTION
Use Diesel Exhaust Fluid only. Failure
to do so may damage components of
the Diesel Particulate Filter (DPF).
Besides empty and full, the gauge also
indicates 1/4, 1/2, and 3/4 of total capacity.
DEF fluid is required to meet certain
emission requirements. Do not allow your
DEF tank to remain empty. Please refer to
your emission supplemental manual for
more details about DEF fluid.
Vehicle Air Pressure
The Primary Air Pressure gauge indicates
pressure in the rear braking system. The
Secondary gauge indicates pressure in the
front braking system.
Each gauge indicates the amount of air
pressure in each system in pounds per
square inch (psi). On vehicles equipped
with metric air pressure gauges, the gauge
