Glow plug pre-heat indicator:
With the key in the on position,
the
light will illuminate if glow
plug heat is necessary as a starting aid. Wait until the light goes off
before starting. Refer to
Cold weather starting
in the
Driving
chapter
of this supplement. After the engine starts, the light should turn on. The
light should always illuminate at least momentarily when the engine is
cold and the ignition is turned to on. If it does not illuminate, the glow
plug system should be checked and repaired promptly to avoid difficulty
in cold starting.
Water in fuel:
E-Series
F-Super Duty
During refueling, it is possible for water-contaminated diesel fuel to be
pumped into your tank. Your vehicle’s fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to start (as part of
the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer to
Draining the FCM/HFCM and changing the fuel filters
in the
Maintenance and Specifications
chapter of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
WARNING:
Do not drain the water separator while the engine is
running. Fuel may ignite if the separator is drained while the
engine is running or the vehicle is moving.
