CAUTION!
Do not drain the fuel/water separator filter when the
engine is running.
Drain a small amount from the fuel/water separator
filter periodically or when the WATER IN FUEL indicator
lamp is on. Pull outward on the drain valve lever, located
on the side of the filter, and allow any accumulated water
to drain. Hold the drain valve open until all water and
contaminants have been removed. Close the drain release
valve, by returning it to the inward position, when clean
fuel is visible.
NOTE:The Fuel / Water separator drain valve is
identified by its yellow handle and is located on the
inboard side of the fuel filter housing.If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to

run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.
4. Repeat the procedure if the engine does not start.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
CAUTION!
Diesel fuel will damage black top paving surfaces.
Drain the filter into an appropriate container.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and be hazardous or explosive when mixed with
diesel fuel.

•Off-road or desert operation.
•Extensive operation at high engine speeds (greater
than 2900 rpm) and loads (greater than 70% throttle).
NOTE:Most vehicles are operated under the conditions
listed for ScheduleB.
NOTE:IfANYof these apply to you then change your
coolant every 101,250 miles (162 000 km) or 60 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
Second is Schedule“A”. It is for vehicles that are not
operated under any of the conditions listed under Sched-
uleB.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level about 15 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.
•Drain water from the fuel filter.
