Starting and Stopping the Engine
|
Always open the garage door before you start the engine.
|
WARNING: Extended idling at high engine speeds can produce very high temperatures in the engine and exhaust system, creating the risk of fire or other damage.
WARNING: Do not park, idle or drive your vehicle on dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, creating the risk of fire. 
WARNING: Do not start the engine in a closed garage or in other enclosed areas. Exhaust fumes can be toxic.
WARNING: Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your vehicle inspected immediately. Do not drive if you smell exhaust fumes.If you disconnect the battery, your vehicle may exhibit some unusual driving characteristics for approximately 5.0 mi (8 km) after you reconnect it. This is because the engine management system must realign itself with the engine. You can disregard any unusual driving characteristics during this period.
The powertrain control system meets all Canadian interference-causing equipment standard requirements regulating the impulse electrical field or radio noise.
When you start the engine, avoid pressing the accelerator pedal before and during operation. Only use the accelerator pedal when you have difficulty starting the engine.
If your vehicle is operated in a heavy snow storm or blowing snow conditions, the engine air induction may become partially clogged with snow and ice. If this occurs, the engine may experience a significant reduction in power output. At the earliest opportunity, clear all the snow and ice away from the air induction inlet.
E
0 (off) - The ignition is off.
Note: When you switch the ignition off and leave your vehicle, do not leave your key in the ignition. This could cause your vehicle battery to lose charge.
I (accessory) - Allows the electrical accessories, such as the radio, to operate while the engine is not running.
173
Note: Do not leave the ignition key in this position for too long. This could cause your vehicle battery to lose charge.
Note: The keyless starting system may not function if the key is close to metal objects or electronic devices such as cellular phones.
Note: A valid key must be located inside your vehicle to switch the ignition on and start the engine.
The keyless starting system has three modes:
Off: Turns the ignition off.
• Without applying the clutch pedal (manual transmission) or brake pedal (automatic transmission), press and release the button once when the ignition is in the on mode, or when the engine is running but the vehicle is not moving.
On: All electrical circuits are operational and the warning lamps and indicators illuminate.
• Without applying the clutch pedal (manual transmission) or brake pedal (automatic transmission), press and release the button once.
Start: Starts the vehicle. The engine may not start when the vehicle starts.
• Press the clutch pedal (manual transmission) or brake pedal (automatic transmission), and then press the button for any length of time. An indicator light on the button illuminates when then ignition is on and when the engine starts.
When you start the engine, the idle speed increases. This helps to warm up the engine.
If the engine idle speed does not slow down automatically, have your vehicle checked by an authorized dealer.
Before starting the engine check the following:
• Make sure all occupants have fastened their safety belts.
• Make sure the headlamps and electrical accessories are off.
• Make sure the parking brake is on.
• Move the transmission selector lever to position P.
• Turn the ignition key to the on position.
Note: Do not touch the accelerator pedal.
174
3. When the engine starts, release the key and then gradually release the brake pedal as the engine speed increases.
Note: The engine may continue cranking for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the first try, wait for a short period and try again.
Note: Do not touch the accelerator pedal.
Do not crank the engine for more than 10 seconds as starter damage may occur. If the engine does not start, switch the ignition off and wait 30 seconds before trying again.
Note: Do not touch the accelerator pedal.
Note: If the push button ignition switch is pressed again prior to the engine starting the ignition will switch to accessory mode and will not start.
Note: If the brake pedal is released before the engine has started, follow the engine start sequence again.
If you cannot start the engine after three attempts, wait 10 seconds and follow this procedure:

WARNING: Switching off the engine when your vehicle is still moving results in a significant decrease in braking assistance. Higher effort is required to apply the brakes and to stop your vehicle. A significant decrease in steering assistance could also occur. The steering does not lock, but higher effort could be required to steer your vehicle. When you switch the ignition off, some electrical circuits, for example airbags, also turn off. If you unintentionally switch the ignition off, shift into neutral (N) and restart the engine.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 of time. The ignition also turns off in order to save battery power. Before the engine shuts down, a
175
message appears in the information display showing a timer counting down from 30 seconds. If you do not intervene within 30 seconds, the engine shuts down. Another message appears in the information display to inform you that the engine has shut down in order to save fuel. Start your vehicle as you normally do.
The starting characteristics of all grades of E85 ethanol make it unsuitable for use when ambient temperatures fall below 0°F (-18°C). Consult your fuel distributor for the availability of winter grade ethanol. As the outside temperature approaches freezing, ethanol fuel distributors should supply winter grade ethanol, the same as with unleaded gasoline.
If summer grade ethanol is used in cold weather conditions, 0°F (-18°C), you may experience increased cranking times, rough idle or hesitation until the engine has warmed up.
You may experience a decrease in performance when the engine is cold when operating on E85 ethanol.
Do not use starting fluid such as ether in the air intake system. Such fluid could cause immediate explosive damage to the engine and possible personal injury.
If you should experience cold weather starting problems on E85 ethanol, and neither an alternative brand of E85 ethanol nor an engine block heater is available, the addition of unleaded gasoline to your tank improves cold starting performance. Your vehicle is designed to operate on E85 ethanol alone, unleaded gasoline alone, or any mixture of the two.

WARNING: Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment. If you smell exhaust fumes inside your vehicle, have your vehicle inspected immediately. Do not drive if you smell exhaust fumes.Important Ventilating Information
If you stop your vehicle and then leave the engine idling for long periods of time, we recommend that you do one of the following:
• Open the windows at least 1 inch (2.5 centimeters).
• Set your climate control to outside air.
Read all starting instructions carefully before you start your vehicle.
For temperatures below 32°F (0°C), the use of the correct grade engine oil is essential for proper operation. Refer to engine oil specifications for more information. See Capacities and Specifications (page 431).
176
Your vehicle may have a cold weather starting strategy that prevents severe engine damage by assisting in engine lubrication warm-up. In extremely cold ambient temperatures, this strategy activates and prevents the accelerator pedal from being used for 30 seconds after you start your vehicle. A message appears in the information display as your vehicle warms up. By not allowing the accelerator pedal to be used, the engine oil is allowed to properly lubricate the bearings preventing engine damage due to lack of proper lubrication. After the 30 second warm-up period, the accelerator pedal will be operational again and a message appears informing you the vehicle is ok to drive.
When you start the engine in extremely cold temperatures -15°F (-26°C), we recommend that you allow the engine to idle for several minutes before you drive the vehicle.
Before starting the engine check the following:
Note: Do not press the accelerator during starting.
Note: Do not touch the accelerator pedal.
Note: A message will appear Engine Start Pending, Please Wait.
Do not crank the engine for more than 10 seconds as starter damage may occur. If the engine does not start, switch the ignition off and wait 30 seconds before trying again.
Note: Do not touch the accelerator pedal.
Note: If the push button ignition switch is pressed again prior to the engine starting the ignition will switch to accessory mode and will not start.
Note: If the brake pedal is released before the engine has started, follow the engine start sequence again.
Note: A message will appear Engine Start Pending, Please Wait.
The diesel engine glow system consists of:
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
177
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.
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. If you do not intervene within 30 seconds, the engine shuts down. Another message appears in the information display to inform you that the engine has shut down in order to save fuel. Start your vehicle as you normally do.

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 add gasoline, gasohol, alcohol or kerosene to diesel fuel. This creates a serious fire hazard and causes engine performance problems.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 181).
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 will 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.
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 Capacities and Specifications (page 431).
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
178
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 Capacities and Specifications (page 431).
Your vehicle has a fuel and water separator that recirculates fuel from the engine to help prevent fuel filter clogging. To avoid engine fuel starvation during cold weather operation of 32°F (0°C) or below, we recommend that the fuel level in your tank should not drop below ¼ full. This helps prevent air from entering the fuel system and stalling the engine.
Your vehicle has a selective catalytic reduction system that uses Diesel Exhaust Fluid (DEF) to operate properly. You need to replenish your vehicle’s DEF at certain intervals. When filling your vehicle’s DEF tank in cold weather, take special care to prevent damage to the tank. See Selective Catalytic Reductant System (page 196).
In cold weather below 32°F (0°C), the engine may slowly increase to a higher idle speed if you leave it idling in park (P). As the engine warms-up, the engine sound level decreases due to the activation of PCM-controlled sound reduction features.
If you operate your vehicle in a heavy snowstorm or blowing snow conditions, snow and ice can clog the engine air induction. If this occurs, the engine may experience a significant reduction in power output. At the earliest opportunity, clear all the snow and ice away from inside the air filter assembly. Remove the air cleaner cover and the air filter and remove any snow or ice. Remove any debris, snow or ice, on the foam filter by brushing the surface with a soft brush. Once you have cleared all of the debris, reinstall the air filter and cover.
Do not use water, solvents, or a hard brush for cleaning the foam filter.

WARNING: To reduce the risk of vehicle damage and personal burn injuries, do not start your engine with the air cleaner removed and do not remove it while the engine is running.In order to operate the engine in temperatures of 32°F (0°C) or lower, read the following instructions:
-20°F (-29°C) or lower, consult your truck dealer for information about special cold weather equipment and precautions.
179
We recommend the following cold weather idling guidelines:
• You can use Motorcraft® cetane improvers or non-alcohol-based cetane improvers from a reputable manufacturer as needed.
• Maintain the engine cooling system properly.
• Avoid shutting the engine down after an extensive idling period. Drive your vehicle for several miles with the engine at normal operating temperatures under a moderate load.
• Consider using an engine block heater.
• For extended idle times use an approved idle speed increase device.
The following information is a guideline only and is not to be the only source of possible solutions in resolving extreme cold temperature issues.

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.The use of the factory engine block heater assists in engine starting in extreme cold ambient temperatures See Engine Block Heater (page 181).
Your vehicle may have a factory option for a stationary elevated idle control through the upfitter switches in the overhead console. This allows the operator to elevate the idle RPM for extended idle periods, as well as aftermarket equipment such as PTO operation. You must configure this feature even if ordered from the factory. See your authorized dealer for required upfitting.
Vehicle operation in heavy snowfall or extreme rain conditions may feed excessive amounts of snow or water into the air intake system. This could plug the air filter with snow and may cause the engine to lose power and possibly shut down.
We recommend the following actions after operating your vehicle up to 200 mi
(320 km) in snowfall or extreme rain:
• Snow: At the earliest opportunity, open the hood and clear all the snow and ice from the air filter housing inlet (do not remove the foam filter) and reset the air filter restriction gauge.
Note: Removal of the foam filter degrades your vehicle performance during snow and hot weather conditions.
• Extreme rain: The air filter dries after about 15–30 minutes at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge.
Refer to Air filter and restriction gauge in the Maintenance chapter for more information. See Changing the Engine Air Filter (page 362).

Ingestion of water into the diesel engine can result in immediate and severe damage to the engine. If driving through water, slow down to avoid splashing water into the intake. If the engine stalls, and you suspect ingestion of water into the engine, do not try to restart the engine. Consult your dealer for service immediately.
Your fuel tank vents to the atmosphere by valves on top of the tank and through the fuel cap. If water reaches the top of the tank, the valves may pull water into the fuel tank. Water in the fuel can cause performance issues and damage the fuel injection system.

Switch the ignition off.
To help prolong engine life, we recommended you allow the engine to idle for three to five minutes, especially after any of the following:
• Continuous engine speed.
• High ambient temperature.
• High GVW or GCW operation, for example heavy loads or trailers.
This allows the turbo charged engine to cool down.
Your vehicle may be equipped with an engine idle shutdown system. This system automatically shuts down your engine when it has been idling in P (Park) or N (Neutral) for five minutes (parking brake set) or 15 minutes (parking brake not set). When the engine idle shutdown process has started:
181
• A chime sounds and the information display will show ENGINE TURNS OFF IN 30 (seconds) and start counting down
• You can restart the five or 15-minute timer by changing the position of the accelerator pedal, brake pedal or the park brake within the final 30 seconds
• When the timer reaches zero, the engine shuts down and this message will appear in your information display ENGINE TURNED OFF
• One minute after the engine has shut down, the electrical system simulates key off, even though the ignition is still in the on position, initiating normal accessory delay period
• You must move the ignition to the off position to reset the system before restarting your vehicle.
The engine idle shutdown idle timer does not start if:
• The engine is operating in power take-off mode.
• The engine coolant temperature is below 60°F (16°C).
• The exhaust emission control device is regenerating.
ENGINE BLOCK HEATER (IF EQUIPPED)

WARNING: Failure to follow engine block heater instructions could result in property damage or serious personal injury.
WARNING: Do not use your heater with ungrounded electrical systems or two-pronged adapters. There is a risk of electrical shock.Note: The heater is most effective when outdoor temperatures are below 0°F
(-18°C).
For cold climates that are below 0°F (-18°C) needing a temporary battery
installation. Order the cold climate pack.
The heater acts as a starting aid by warming the engine coolant. This allows the climate control system to respond quickly. The equipment includes a heater element (installed in the engine block) and a wire harness. You can connect the system to a grounded 120-volt AC electrical source.
We recommend that you do the following for a safe and correct operation:
• Make sure your vehicle is parked in a clean area, clear of combustibles.
• locate the block heater cord in the front tow hook pocket.
• Use a 16-gauge outdoor extension cord that is product certified by Underwriter’s Laboratory (UL) or Canadian Standards Association (CSA). This extension cord must be suitable for use outdoors, in cold temperatures, and be clearly marked Suitable for Use with Outdoor Appliances. Do not use an indoor extension cord outdoors. This could result in an electric shock or become a fire hazard.
• Use as short an extension cord as possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the extension cord plug and heater cord plug connections are free and clear of water. This could cause an electric shock or fire.
• Make sure the heater, heater cord and extension cord are firmly connected.
• Check for heat anywhere in the electrical hookup once the system has been operating for approximately 30 minutes.
• Make sure the system is unplugged and properly stowed before starting and driving your vehicle. Make sure the protective cover seals the prongs of the block heater cord plug when not in use.
• Make sure the heater system is checked for proper operation before winter.
Make sure the receptacle terminals are clean and dry prior to use. Clean them with a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours of energy per hour of use. The system does not have a thermostat. It achieves maximum temperature after approximately three hours of operation. Using the heater longer than three hours does not improve system performance and unnecessarily uses electricity.
