During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator illuminates
when the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 187).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.

Diesel Engine Fast Start Glow Plug
System
The diesel engine glow system consists of:
• Eight glow plugs, one per cylinder.
• Glow Plug Control Module.
• Engine Coolant Temperature sensor.
• Barometric pressure sensor.
• Environmental temperature sensor.
The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on, the glow plug control module
immediately energizes the glow plugs. The
glow plug control module uses the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor to determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase.

Automatic Engine Shutdown
If your vehicle is equipped with a keyless
ignition, it has a feature that automatically
shuts down the engine if it has been idling
for an extended period. The ignition also
turns off in order to save battery power.
Before the engine shuts down, a message
appears in the information display showing
a timer counting down from 30 seconds.

Cold Weather Starting
WARNING: Do not use starting
fluid, for example ether, in the air intake
system. Such fluid could cause
immediate explosive damage to the
engine and possible personal injury. WARNING:
Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
We recommend that the engine block
heater be used for starting when the
temperature is -9°F (-23°C) or colder. See
Engine Block Heater
(page 182).
When operating in cold weather, you may
use Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer as needed. Switch the ignition on. Do not
start the engine until the
glow-plug indicator turns off. When the glow plug pre-heat indicator
turns off, turn the key to start. After you
start the engine, the glow plugs may
remain on for a period. If you do not start
the engine before the glow plug activation
time ends, you need to reset the glow plugs
by switching the ignition off. After the
engine starts, allow it to idle for about 15
seconds. This protects the engine. Do not
increase engine speed until the oil pressure
gauge indicates normal pressure.
Cold Weather Operation
Note:
Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Change to a lighter grade engine oil to
make starting easier under these
conditions. Refer to engine oil
specifications. See
Engine Oil Capacity
and Specification (page 449).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See
Engine Oil Capacity and
Specification (page 449).
