The glow plug system is
electronically controlled by the PCM
and GPCM. The GPCM energizes the
glow plugs immediately after the
ignition is turned on and kept on as determined by the GPCM using the
ECT, BARO and environmental temperature sensor. The required time
for the glow plugs to be energized decreases as the coolant temperature,
barometric pressure and environmental temperature increase.
Engine and secondary cooling system
The cooling system contains an engine cooling loop to cool the engine
and a secondary cooling loop to cool the transmission, exhaust gas
recirculation (EGR), charge air and fuel. The coolant serves three
primary purposes: to provide heat transfer, freeze point protection, and
corrosion protection using additives.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors may cause the additives in
the coolant to “wear out” in a shorter time. Refer to theSpecial
operating conditionssection for more information about coolant
additives and coolant change intervals. Operating the engine with
insufficient coolant and/or coolant additive can cause severe engine
damage.
Selective catalytic reduction (SCR) system
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. This system relies on the use of diesel
exhaust fluid (DEF) which must be replenished at certain intervals.
Failure to maintain proper DEF levels or if the DEF becomes
contaminated will result in vehicle speed limitations and/or result in the
vehicle entering an idle-only mode. SeeSelective catalytic reduction
(SCR) systemin theMaintenance and Specificationschapter for more
information.
Speed control (if equipped)
If vehicle speed goes outside a predetermined range from the set speed,
the RES (Resume) function will not reset vehicle speed. Vehicle speed
will need to be reset with the SET +/- button after reaching desired
speed using accelerator pedal.

Multi-point inspection
In order to keep your vehicle running right, it is important that you have
the systems on your vehicle checked regularly. This can help identify any
potential issue before there are any problems. Ford Motor Company
suggests the following multi-point inspection to be performed at every
scheduled maintenance interval as the way to ensure your vehicle keeps
running right.
Multi-point inspection - recommended each visit
Accessory drive belt(s) Holes/Slots in the tail-pipe to make
sure they are functional and clear of
debris
Battery performance Horn operation
Engine air filter Radiators, coolers and heater and air
conditioning hoses
Exhaust system Shocks and struts and other
suspension components for leaks and
damage
Exterior lamps and hazard
warning system operationTires for wear and check air pressure,
including spare
Fluid levels*; fill if necessary Windshield for cracks, chips and
pitting
For oil and fluid leaks Windshield washer spray and wiper
operation
*Brake, engine coolant reservoir, secondary low-temperature cooling
system reservoir, automatic transmission, power steering and window

Normal Scheduled Maintenance
At every oil change
interval as indicated
by the message
centerChange engine oil and filter
Refill diesel exhaust fluid tank
Rotate tires, inspect tire wear and measure tread
depth; vehicles equipped with dual rear wheels
should only rotate the rear wheels if unusual
wear is observed
Perform multi-point inspection (recommended)
Inspect air filter restriction gauge, replace filter
as necessary
Inspect automatic transmission fluid level
Inspect brake pads, shoes, rotors, drums, brake
linings, hoses and parking brake
Inspect cabin air filter (if equipped)
Inspect engine cooling system strength and hoses
Inspect exhaust system and heat shields
Inspect front axle and U-joints; lubricate if
equipped with grease fittings (4WD vehicles)
Inspect half-shaft boots (if equipped)
Inspect steering linkage, ball joints, suspension,
tie-rod ends, driveshaft and U-joints; lubricate if
equipped with grease fittings
Inspect wheels and related components for
abnormal noise, wear, looseness or drag
Reset your Intelligent Oil Life Monitor™ after each engine oil and filter
change; refer to theInstrument Clusterchapter in yourOwner’s
Guide.
Do not exceed one year or 10,000 miles (16,000 km) between
service intervals
