If The Vehicle’s Speed Is Limited Or The Vehicle Has Entered An Idle-Only Mode; Cold Weather Starting - Ford Diesel 2012 Supplement Manual

If the vehicle's speed is limited or the vehicle has entered an
idle-only mode
If the vehicle's speed is limited or in an idle-only mode, the SCR system
may be limiting the vehicle's functions due to low or contaminated diesel
exhaust fluid (DEF). Check the DEF. See Selective catalytic reduction
(SCR) system in the Maintenance and Specifications chapter for more
information.

Cold weather starting

It is recommended that the engine block heater be used for starting
when the temperature is -10°F (-23°C) or colder. Refer to Engine block
heater (if equipped) in the Driving chapter of the Owner's Guide.
When operating in cold weather, use Motorcraft cetane improvers or
non alcohol-based cetane improvers from a reputable manufacturer.
Do not crank the engine for more than 10 seconds as starter damage
may occur. If the engine fails to start, turn the key to 3 (off) and wait
30 seconds before trying again.
WARNING: Do not use starting fluid, such as ether, in the air
intake system (see air filter decal). Such fluid could cause
immediate explosive damage to the engine and possible personal injury.
WARNING: Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard and causes
engine performance problems.
1. Turn the key to on without turning the key to start. Do not start the
engine until the glow-plug pre-heat indicator
2. When the glow plug pre-heat
indicator turns off, turn the key to
start, then release the key as soon
as the engine starts. The glow plugs
may remain on for a period of time after engine start. If the engine is not
started before the glow plug activation time ends, the glow plugs will
need to be reset by turning the key to off.
3. After the engine starts, allow it to idle for about 15 seconds. This
is to protect the engine. Do not increase engine speed until the oil
pressure gauge indicates normal pressure.
