Note: You may have to slightly rotate the steering wheel to assist unlocking it.
STARTING A GASOLINE ENGINE (IF EQUIPPED)
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.
Note: You can crank the engine for a total of 60 seconds (without the engine starting) before the starting system temporarily disables. The 60 seconds does not have to be all at once. For example, if you crank the engine three times for 20 seconds each time, without the engine starting, you reached the 60-second time limit. A message appears in the information display alerting you that you exceeded the cranking time. You cannot attempt to start the engine for at least 15 minutes. After 15 minutes, you are limited to a 15-second engine cranking time. You need to wait 60 minutes before you can crank the engine for 60 seconds again.
Before starting the engine, check the following:
- Make sure all occupants have fastened their seatbelts.
- 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 on. If your vehicle is equipped with a keyless ignition, see the following instructions.

Important Ventilating Information
If you stop your vehicle and leave the engine idling for long periods, we recommend that you do one of the following:
- Open the windows at least 1 in (2.5 cm).
- Set your climate control to outside air.
STARTING A DIESEL ENGINE (IF EQUIPPED)
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 .
Your vehicle may be equipped with 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 starting your vehicle. A message will appear 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 will appear informing you the vehicle is ok to drive.
When starting the engine in extremely cold temperatures -15°F (-26°C), it is recommended to allow the engine to idle for several minutes before driving the vehicle.
Before starting the engine check the following:
- Make sure all occupants have fastened their seatbelts.
- Make sure the headlamps and electrical accessories are off.
- Make sure the parking brake is on.
- Make sure the transmission is in park (P).
Note: Do not press the accelerator during starting.
Vehicles with Keyless Start
Note: Do not touch the accelerator pedal.
Note: If the push button ignition switch is pressed again prior to the engine starting, the ignition switches to accessory mode and does not start.
Note: If the brake pedal is released before the engine has started, follow the engine start sequence again.
- Fully depress the brake pedal.
- Press the center of the push button ignition switch.
Note: A message displays Engine Start Pending, Please Wait.
- When the engine starts, release the brake pedal.
Diesel Engine Fast Start Glow Plug System
The diesel engine glow system consists of:
- Six or 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 using the engine coolant temperature, barometric pressure sensor and environmental temperature sensor will 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. 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.
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.
It is recommended that the engine block heater be used for starting when the temperature is -9°F (-23°C) or colder. See Engine Block Heater .
When operating in cold weather, Motorcraft® cetane improvers or non-alcohol-based cetane improvers from a reputable manufacturer may be used as needed.
Do not crank the engine for more than 10 seconds as starter damage may occur. If the engine fails to start, switch the ignition off and wait 30 seconds before trying again.
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 and release the key as soon as the engine starts. After starting 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 is to protect the engine. Do not increase engine speed until the oil pressure gauge indicates normal pressure.
For vehicles with keyless start:
- Fully depress brake pedal and hold to allow time for glow-plugs to heat.
- Press and release the start button.
Note: A message «Engine Start Pending, Please Wait», along with the glow plug indicator displays on the instrument cluster.
- When the engine starts, release the brake pedal.
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.
Changing to a lighter grade engine oil also makes starting easier under these conditions. Refer to Engine oil specifications. See Capacities and Specifications (page 433).
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 Capacities and Specifications (page 433).
Your vehicle is equipped with 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 recommended that the fuel level in your tank should not drop below 1⁄4 full. This helps prevent air from entering the fuel system and stalling the engine.
In cold weather below 32°F (0°C), the engine may slowly increase to a higher idle speed if left 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/or ice away from inside the air filter assembly. Remove the air cleaner cover and the pleated paper filter, leaving the foam filter in and remove any snow or ice. Make sure you install the foam filter correctly in place. Remove any debris, snow or ice on the foam filter by brushing the surface with soft brush. Once you have cleared all of the debris, reinstall the air filter and assembly.
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:
- Make sure that the batteries are of sufficient size and are fully charged. Check other electrical components to make sure they are in optimum condition.
- Use the proper coolant solution at the concentration recommended protecting the engine against damage from freezing.
- Try to keep the fuel tank full as much as possible at the end of operation to prevent condensation in the fuel system.
- Make sure you use proper cold weather engine oil and that it is at its proper level. Also, if necessary, make sure to follow the engine oil and filter change schedule found under the Special operating conditions section listed in the scheduled maintenance information.
- At temperatures of -9°F (-23°C) or below, it is recommended that you use an engine block heater to improve cold engine starting.
- If operating in arctic temperatures of -20°F (-29°C) or lower, consult your truck dealer for information about special cold weather equipment and precautions.
The following cold weather idling guidelines are recommended:
- 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.
Winter Operating Tips for Arctic Operation -20°F (-29°C) and Below
The following information is a guideline only and is not to be the only source of possible solutions in resolving extreme cold temperature issues.
Starting Aids
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 .
Idle Control
Your vehicle may have a factory option for a stationary elevated idle control through dash-mounted upfitter switches that 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.
Operation in Snow and Rain
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 .
Operation in Standing Water
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.
SWITCHING OFF THE ENGINE
Allow the engine to idle for three to five minutes before shutting it down. The larger the engine, the greater the need is for this idling period.
Note: Try to limit engine idle to 10 minutes.
Excessive idling reduces fuel economy.
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.
WARNING: Do not fully close the hood, or allow it to drop under its own weight when using the engine block heater. This could damage the power cable and may cause an electrical short resulting in fire, injury and property damage.
Note: The heater is most effective when outdoor temperatures are below 0°F (-18°C).
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:
- 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.
- If the block heater cord is under the hood, Do Not remove the wiring from its original location. Do Not close the hood on the extension wiring.
- Make sure your vehicle is parked in a clean area, clear of combustibles.
- 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.
Using the Engine Block Heater
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.
