FUEL FILTER REPLACEMENT (stage
2)
NOTE:● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system. ●
If the “Low Fuel Pressure Service Fuel
System” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle and restart the vehicle. If the mes-
sage is still displayed or the Malfunc-
tion Indicator Light is illuminated after
a full key cycle , it is recommended that
you visit a NISSAN dealer for service.
● For additional information on the loca-
tion of the fuel filter (stage 2) , refer to
the “Engine compartment check loca-
tions” in this section.
WARNING
● The fuel system (fuel pump, high pres-
sure fuel lines, fuel rail, injectors) con-
tain very high pressure fuel. To avoid the
risk of personal injury or fire;
– Do not loosen any fittings while the engine is running.
– Wait at least 10 minutes after shut- ting down the engine before loosen-
ing any fittings in the high-pressure
fuel system to allow pressure to de-
crease to a lower level.

DRAINING WATER
WARNING
To avoid the risk of personal injury or fire,
drain diesel fuel into an approved con-
tainer and safely dispose of in accordance
with local environmental regulations.
CAUTION
Continuing vehicle operation without
properly draining could cause serious
damage to the engine.1. Shut the engine off. 2. Place a large drain pan under the drain valve
A.
3. Turn the drain valve counterclockwise1/4
turn to open.
4. Drain the filter sump until clear fuel is visible. If draining the stage 1 fuel filter housing,
drain until fuel reduces to a trickle.
5. Turn the drain valve clockwise1/4 turn to
close.
FUEL SYSTEM PRIMING
WARNING
The fuel pump, high-pressure fuel lines,
and fuel rail contain very high-pressure
fuel. To reduce the possibility of personal
injury, never loosen any fittings while the
engine is running.
NOTE: ● It is not necessary to vent air from the
high-pressure fuel system before start-
ing the engine.
● Upon ignition on the electric lift pump
will run until the fuel system is primed
or 90 seconds, whichever comes first. Purge the air out of the fuel system after refilling a
completely empty fuel tank by the following pro-
cedure:
1. Turn the key ON for 90 seconds to prime the fuel system. After 90 seconds, crank the
engine for a maximum of 30 seconds or until
the engine starts. If the engine does not
start, repeat this step.
2. When the engine does start, it may operate erratically and with increased noise levels for
a few minutes. This is a normal condition as
air is being removed from the system.
NOTE:
It is possible for a warning or indicator light
to illuminate due to air entering the fuel
system. If this happens, it is recommended
that you visit a NISSAN dealer for service.
