sensor to determine how long the glowplugs stay energized. The required time forthe glow plugs to be energized decreasesas the coolant temperature, barometricpressure and environmental temperatureincrease.
Cold Weather Starting
WARNINGS
Do not use starting fluid, for exampleether, in the air intake system. Suchfluid could cause immediateexplosive damage to the engine andpossible personal injury.
Do not add gasoline, gasohol, alcoholor kerosene to diesel fuel. Thiscreates a serious fire hazard andcauses engine performance problems.
We recommend that the engine blockheater be used for starting when thetemperature is -9°F (-23°C) or colder. SeeEngine Block Heater (page 181).
When operating in cold weather, you mayuse Motorcraft® cetane improvers ornon-alcohol-based cetane improvers froma reputable manufacturer as needed.
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine does not start, switch theignition off and wait 30 seconds beforetrying again.
Switch the ignition on. Do notstart the engine until theglow-plug indicator turns off.
When the glow plug pre-heat indicatorturns off, turn the key to start. After youstart the engine, the glow plugs mayremain on for a period. If you do not startthe engine before the glow plug activationtime ends, you will need to reset the glowplugs by switching the ignition off. Afterthe engine starts, allow it to idle for about15 seconds. This protects the engine. Donot increase engine speed until the oilpressure gauge indicates normal pressure.
Cold Weather Operation
Note:Idling in cold weather does not heatthe engine to its normal operatingtemperature. Long periods of idling,especially in cold weather, can cause abuildup of deposits which can cause enginedamage.
Change to a lighter grade engine oil tomake starting easier under theseconditions. Refer to engine oilspecifications. See Capacities andSpecifications (page 427).
Diesel fuel is adjusted seasonally for coldtemperatures. Diesel fuel which has notbeen properly formulated for the ambientconditions may gel which can clog the fuelfilters. One indication that the fuel filter(s)may be clogged is if the engine starts, stallsafter a short time, and then does notrestart. If you have been using biodiesel,you may need to use a fuel with lowerbiodiesel content, try another brand, ordiscontinue using biodiesel. Do not usealcohol based additives to correct fuelgelling. This may result in damage to thefuel injectors and system. Use the properanti-gel and performance improvementproduct. See Capacities andSpecifications (page 427).

Starting and Stopping the Engine

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics.
Avoid driving too fast during the first1,000 mi (1,600 km). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Drive your new vehicle at least 1,000 mi(1,600 km) before towing a trailer. Makesure you use the specified engine oil. SeeCapacities and Specifications (page422).
Do not add friction modifier compoundsor special break-in oils during the first fewthousand miles (kilometers) of operation.These additives may prevent piston ringseating.
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
