Turbocharger
This cooling-down practice is especially
important on a turbocharged engine. The
turbocharger contains bearings and seals
that are subjected to hot exhaust gases.
While the engine is operating, heat is
carried away by circulating oil. If you stop
the engine suddenly
, the temperature of
the turbocharger could rise as much as
100°F (55°C) above the temperature
reached during operation. A sudden rise in
temperature like this could cause the
bearings to seize or the oil seals to loosen.
Refueling
Air space in your fuel tanks allows water to
condense there. To prevent this
condensation while you are stopped, fill
your tanks to 95 percent of capacity. When
refueling, add approximately the same
amount to each fuel tank on vehicles with
more than one tank.
WARNING
DO NOT carry additional fuel contain-
ers in your vehicle. Fuel containers, ei-
ther full or empty, may leak, explode,
and cause or feed a fire. Failure to
comply may result in death or personal
injury
.
WARNING
Diesel fuel in the presence of an igni-
tion
source could cause an explosion.
A mixture of gasoline or alcohol with
diesel fuel increases this risk of explo-
sion. DO NOT remove a fuel tank cap
near an open flame. Use only the fuel
and/or additives recommended for
your engine. Failure to comply may re-
sult in death, personal injury, equip-
ment or property damage.
CAUTION
Use only Ultra Low Sulfur Diesel
(ULSD)
Fuel, as recommended by en-
gine manufacturers. If you need further
information on fuel specifications, con-
sult the Engine Operation and Mainte-
nance Manual.
If your vehicle is equipped with fuel shut off
valves for the take-of
f and return lines, they
are located on the fuel lines entering the
top of the fuel tank. Fuel shut off valves for
the fuel crossover line are on the bottom of
the fuel tank, at the crossover line
connection.
Final Stopping Procedures
Y
our vehicle will be easier to start driving
when you are ready, and it will be safer for
anyone who might be around it. Please
remember, too, that in some states it is
illegal to leave the engine running and the
vehicle unattended.
WARNING
Using the trailer hand brake or air
brakes to hold a parked vehicle is dan-
gerous. Because they work with air
pressure, these brakes could come
loose. Your vehicle could roll, causing
an accident involving death or person-
al injury. Always set the parking
brakes. Never rely on the trailer hand
brake or truck air brakes to hold a
parked vehicle.
