ENGINE COOLANT CHECK - 6.2L/6.8L

Never remove the coolant reservoir cap when the engine is running or hot.

Do not put coolant in the windshield washer reservoir. If sprayed on the windshield, coolant could make it

difficult to see through the windshield.

To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure

relief cap. The cooling system is under pressure. Steam and hot liquid can come out forcefully when you loosen the cap slightly.

Do not add coolant further than the

MAX mark.

When the engine is cold, check the concentration and level of the coolant at the intervals listed in the scheduled maintenance information. See Scheduled Maintenance (page 581).

Note: Make sure that the coolant level is between the MIN and the MAX marks on the coolant reservoir.

Note: Coolant expands when it is hot. The level may extend beyond the MAX mark.

Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -30°F (-34°C) and -34°F (-37°C). Coolant concentration should be checked using a refractometer. We recommend, Robinair® Coolant and Battery Refractometer 75240 (Rotunda tool part number: ROB75240). We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentration.

Note: Automotive fluids are not interchangeable. Do not use coolant or windshield washer fluid outside of its specified function and vehicle location.

Note: Do not use stop leak pellets, cooling system sealants, or non-specified additives as they can cause damage to the engine cooling or heating systems. Resulting component damage may not be covered by the vehicle Warranty.

Adding Coolant

Never remove the coolant reservoir cap when the engine is running or hot.

338

It is very important to use prediluted coolant meeting the correct specification in order to avoid plugging the small passageways in the engine cooling system. See Capacities and Specifications (page 427). Incorrect prediluted coolant use can cause damage not covered by the vehicle Warranty.

If the coolant level is at or below the minimum mark, add prediluted coolant immediately.

To top up the coolant level do the following:

    Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
    Add prediluted coolant meeting the correct specification. See Capacities and Specifications (page 420).
    Add enough prediluted coolant to reach the correct level.
    Replace the coolant reservoir cap, turn it clockwise until you feel a strong resistance.
    Check the coolant level in the coolant reservoir the next few times you drive your vehicle.

Note: During normal vehicle operation, the coolant may change color from orange to pink or light red. As long as the coolant is clear and uncontaminated, this color change does not indicate the coolant has degraded nor does it require the coolant to be drained, the system to be flushed, or the coolant to be replaced.

Do not mix different colors or types of prediluted coolant in your vehicle. Mixing of prediluted coolant or using an incorrect prediluted coolant may harm the engine or cooling system components and may not be covered by the vehicle Warranty.

In case of emergency, you can add a large amount of water without prediluted coolant in order to reach a vehicle service location. On arrival do the following:

    Drain the cooling system.
    Chemically clean the cooling system. We recommend Motorcraft Premium Cooling System Flush.
    Refill with prediluted coolant as soon as possible.

Water alone, without prediluted coolant, can cause engine damage from corrosion, overheating or freezing.

Do not use the following as a coolant substitute:

Alcohol.

Methanol.

Brine.

Any coolant mixed with alcohol or methanol antifreeze.

Alcohol and other liquids can cause engine damage from overheating or freezing.

Do not add extra inhibitors or additives to the coolant. These can be harmful and compromise the corrosion protection of the coolant.

We do not recommend the use of recycled coolant as an approved recycling process is not yet available.

Dispose of used engine coolant in an appropriate manner. Follow your community’s regulations and standards for recycling and disposing of automotive fluids.

339

If you drive in extremely cold climates:

    It may be necessary to increase the coolant concentration above 50%.
    A coolant concentration of 60% provides improved freeze point protection. Coolant concentrations above 60% decrease the overheat protection characteristics of the coolant and may cause engine damage.

If you drive in extremely hot climates:

    It may be necessary to decrease the coolant concentration to 40%.
    A coolant concentration of 40% provides improved overheat protection. Coolant concentrations below 40% decrease the freeze and corrosion protection characteristics of the coolant and may cause engine damage.

Vehicles driven year-round in non-extreme climates should use prediluted coolant for optimum cooling system and engine protection.

Fail-safe cooling allows you to temporarily drive your vehicle before any incremental component damage occurs. The fail-safe distance depends on ambient temperature, vehicle load and terrain.

If the engine begins to overheat, the coolant temperature gauge moves toward the red zone:

A warning lamp illuminates and a message may appear in the information display.

If the engine reaches a preset

over-temperature condition, the engine automatically switches to alternating cylinder operation. Each disabled cylinder acts as an air pump and cools the engine.

When this occurs, your vehicle still operates, however:

    Engine power is limited.
    The air conditioning system turns off.

Continued operation increases the engine temperature, causing the engine to completely shut down. Your steering and braking effort increases in this situation.

When the engine temperature cools, you can re-start the engine. Have your vehicle checked as soon as possible to minimize engine damage.

Fail-safe mode is for use during emergencies only. Operate your vehicle in fail-safe mode only as long

as necessary to bring your vehicle to rest in a safe location and seek immediate repairs. When in fail-safe mode, your vehicle will have limited power, will not be able to maintain high-speed operation, and may completely shut down without warning, potentially losing engine power, power steering assist, and power brake assist, which may increase the possibility of a crash resulting in serious injury.

Never remove the coolant reservoir cap when the engine is running or hot.

Your vehicle has limited engine power when in the fail-safe mode, drive your vehicle with caution. Your vehicle does not maintain high-speed operation and the engine may operate poorly.

340

Remember that the engine is capable of automatically shutting down to prevent engine damage. In this situation:

    Pull off the road as soon as safely possible and switch the engine off.
    If you are a member of a roadside assistance program, we recommend that you contact your roadside assistance service provider.
    If this is not possible, wait a short period for the engine to cool.
    Check the coolant level. If the coolant level is at or below the minimum mark, add prediluted coolant immediately.
    When the engine temperature cools, you can re-start the engine. Have your vehicle checked as soon as possible to minimize engine damage.

Note: Driving your vehicle without repair increases the chance of engine damage.

Engine Coolant Temperature Management (If Equipped)

To reduce the risk of crash and injury, be prepared that the vehicle speed may reduce and the vehicle may not

be able to accelerate with full power until the coolant temperature reduces.

If you tow a trailer with your vehicle, the engine may temporarily reach higher a temperature during severe operating conditions, for example ascending a long or steep grade in high ambient temperatures.

At this time, you may notice the coolant temperature gauge moves toward the red zone and a message may appear in the information display.

You may notice a reduction in vehicle speed caused by reduced engine power in order to manage the engine coolant temperature. Your vehicle may enter this mode if certain high-temperature and high-load conditions take place. The amount of speed reduction depends on vehicle loading, grade and ambient temperature. If this occurs, there is no need to pull off the road. You can continue to drive your vehicle.

The air conditioning may automatically turn on and off during severe operating conditions to protect the engine from overheating. When the coolant temperature decreases to the normal operating temperature, the air conditioning turns on.

If the coolant temperature gauge moves fully into the red zone, or if the coolant temperature warning or service engine soon messages appear in your information display, do the following:

    Pull off the road as soon as safely possible and shift the transmission into park (P).
    Leave the engine running until the coolant temperature gauge needle returns to the normal position. After several minutes, if the temperature does not drop, follow the remaining steps.
    Switch the engine off and wait for it to cool. Check the coolant level.
    If the coolant level is at or below the minimum mark, add prediluted coolant immediately.
    If the coolant level is normal, restart the engine and continue.

341

Never remove the coolant reservoir cap when the engine is running or hot.

Do not put coolant in the windshield washer reservoir. If sprayed on the windshield, coolant could make it

difficult to see through the windshield.

To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure

Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -30°F (-34°C) and -34°F (-37°C). Coolant concentration should be checked using a refractometer. We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentration.

Do not add engine coolant when the engine is hot. Failure to follow this instruction could result in personal

injury.

Never remove the coolant reservoir cap when the engine is running or hot.

Note: Automotive fluids are not interchangeable. Do not use coolant or windshield washer fluid outside of its specified function and vehicle location.

Note: Do not use stop leak pellets, cooling system sealants, or non-specified additives as they can cause damage to the engine cooling or heating systems. Resulting component damage may not be covered by the vehicle Warranty.

It is very important to use prediluted coolant approved to the correct specification in order to avoid plugging the small passageways in the engine cooling system. See Capacities and Specifications (page 432). Do not mix different colors or types of coolant in your vehicle. Mixing of engine coolants or using an incorrect coolant may harm the engine or cooling system components and may not be covered by the vehicle Warranty.

Note: Coolants marketed for all makes and models may not be approved to Ford specifications and may cause damage to the cooling system. Resulting component damage may not be covered by the vehicle Warranty.

If the coolant level is at or below the minimum mark, add prediluted coolant immediately.

342

For vehicles with overflow coolant systems with a non-pressurized cap on the coolant recovery system, add coolant to the coolant recovery reservoir when the engine is cool. Add prediluted coolant to the maximum level. For all vehicles which have a coolant degas system with a pressurized cap, or if it is necessary to remove the coolant pressure relief cap on the radiator, follow these steps to add engine coolant:

    Turn the engine off and let it cool.
    Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
    Fill the coolant reservoir slowly with prediluted engine coolant to within the minimum and maximum range on the engine coolant reservoir. If you removed the radiator cap in an overflow system, fill the radiator until the coolant is visible and the radiator is almost full. If coolant is added to bring the level within the minimum and maximum range when the engine is not cold, the system may remain under filled.
    Replace the coolant reservoir cap, turn it clockwise until you feel a strong resistance.
    Check the coolant level in the coolant reservoir the next few times you drive your vehicle. If necessary, add enough prediluted engine coolant to bring the coolant level to the proper level.

Note: If prediluted coolant is not available, use the approved antifreeze concentrate diluting it to 50/50 with distilled water. See Capacities and Specifications (page 432). Using water that has not been deionized may contribute to deposit formation, corrosion or plugging of the small cooling system passageways.

If you have to add more than 1.1 qt (1 L) of engine coolant per month, have your vehicle checked as soon as possible.

Operating an engine with a low level of coolant can result in engine overheating and possible engine damage.

Note: During normal vehicle operation, the coolant may change color from orange to pink or light red. As long as the coolant is clear and uncontaminated, this color change does not indicate the coolant has degraded nor does it require the coolant to be drained, the system to be flushed, or the coolant to be replaced.

Note: In case of emergency, you can add a large amount of water without coolant in order to reach a vehicle service location.

Water alone, without coolant, can cause engine damage from corrosion, overheating or freezing. When you reach a service location, you must have the cooling system drained, flushed and refilled using the correct specification prediluted coolant or antifreeze concentrate. See Capacities and Specifications (page 432).

Do not use the following as a coolant substitute:

    Alcohol.
    Methanol.
    Brine.
    Any coolant mixed with alcohol or methanol antifreeze.

Alcohol and other liquids can cause engine damage from overheating or freezing.

Do not add extra inhibitors or non-specified additives to the coolant. These can be harmful and compromise the corrosion protection of the coolant.

343

The following procedure should be used when refilling the engine or secondary cooling systems after it has been drained or become extremely low:

    Before you remove the cap, turn the engine off and let it cool.
    When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise until pressure begins to release.
    Step back while the pressure releases.
    When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap.
    Slowly add prediluted engine coolant to the coolant reservoir until the coolant level is within the minimum and maximum range as listed on the reservoir.
    Reinstall the pressure relief cap.
    Start and run the engine at 2000 rpm for 2 minutes.
    Shut engine off, and remove the pressure relief cap as previously outlined.
    If required, add prediluted engine coolant to the coolant reservoir until the coolant level is within the minimum and maximum range as listed on the reservoir.
    Engine cooling system: Repeat Step 5 until the coolant level has stabilized (is no longer dropping after each step) and the upper radiator hose at the radiator is warm to the touch (indicating that the engine thermostat is open and coolant is flowing through the radiator).
    Check the secondary cooling system. Repeat Step 5 until the coolant level has stabilized (is no longer dropping after each step) and the lower passenger side of the secondary radiator is warm to the touch (indicating secondary thermostat is open and coolant is flowing through the entire system).
    Reinstall the pressure relief cap. Shut the engine off and let it cool.
    Check the coolant level in the reservoir before you drive your vehicle the next few times.
    If necessary, add prediluted engine coolant to the coolant reservoir until the coolant level is within the minimum and maximum range as listed on the reservoir. After any coolant has been added, check the coolant concentration.

We do not recommend the use of recycled coolant as an approved recycling process is not yet available.

Dispose of used engine coolant in an appropriate manner. Follow your community’s regulations and standards for recycling and disposing of automotive fluids.

If you drive in extremely cold climates:

    It may be necessary to increase the coolant concentration above 50%.
    A coolant concentration of 60% provides improved freeze point protection. Coolant concentrations above 60% decrease the overheat protection characteristics of the coolant and may cause engine damage.

344

If you drive in extremely hot climates:

    You can decrease the coolant concentration to 40%.
    Coolant concentrations below 40% decrease the freeze and corrosion protection characteristics of the coolant and may cause engine damage.

Vehicles driven year-round in non-extreme climates should use prediluted engine coolant for optimum cooling system and engine protection.

At specific mileage intervals as listed in the scheduled maintenance information chapter, the coolant corrosion inhibitor additive should be checked. An information message may display in the optional information display at this time. The purpose of checking is to verify the correct engine coolant concentration (freeze point protection) and corrosion inhibitor additive level (strength) of the coolant for maximum engine performance and protection.

Three products are available to confirm the life and health of the coolant, one tool, a test kit and a coolant inhibitor additive:

    Robinair® Coolant and Battery Refractometer 75240 – Recommended refractometer to test coolant concentration. (Rotunda tool part number: ROB75240).
    Rotunda 328-R071–ELC (Antifreeze Coolant ELC Contamination Kit) – Evaluates the corrosion inhibitor additive strength. Note the first step is to verify the vehicle’s coolant concentration is in the correct range of 40 – 60%. Coolant concentrations outside this range will not provide valid test results. If the report results in a pass, for example the cooling system does not show excessive contamination, the corrosion inhibitor additive strength is sufficient, and no action is required. If the report results as insufficient (does not pass), the corrosion inhibitor additive strength of the coolant is too low. If the engine cooling system corrosion inhibitor additive strength is low, add 47 fl oz (1.4 L) of Motorcraft Specialty Orange Engine Coolant Revitalizer. If the secondary cooling system corrosion inhibitor additive strength is low, add 16 fl oz (0.47 L) of Motorcraft Specialty Orange Engine Coolant Revitalizer.
    Motorcraft Specialty Orange Engine Coolant Revitalizer – Additive to boost the corrosion inhibitor level based upon the test results of the Antifreeze Coolant ELC Contamination Kit. The Revitalizer may be added two times over the life of the coolant. If additional dosages are required, the cooling system must be flushed and refilled per the instructions in the Workshop Manual.

Make sure to follow the proper coolant and additive specifications. See Capacities and Specifications (page 420).

345

At specific mileage intervals, as listed in the scheduled maintenance information, the coolant should be changed. The information display may display a message to change coolant at this time. Add prediluted coolant approved to the correct specification. See Capacities and Specifications (page 420).

Your vehicle may have an engine driven cooling fan drive (also called a fan clutch). This fan drive changes the fan speed to match the vehicle’s changing cooling air flow requirements. Fan speed, fan noise level and fuel consumption all will increase based on the driving conditions that include trailer towing, hill climbing, heavy loads, high speed and high ambient temperature, individually or in combination.

The fan drive is designed to provide the minimum fan speed (and resulting minimum fan noise and fuel consumption) required to meet the ever changing vehicle cooling air flow requirements. You will hear the amount of fan noise increasing and decreasing as the engine power requirements and vehicle driving conditions change as you drive. This is to be expected as being normal to the operation of your vehicle. High levels of fan noise might also be heard when your engine is first started, and should normally decrease after driving for a short time.

Have an authorized dealer check and change the transmission fluid and filter at the correct service interval. See Scheduled Maintenance (page 581).

Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.

For scheduled intervals of the fluid checks and changes, See Scheduled Maintenance (page 581). Your transmission does not consume fluid.

However, the fluid level should be checked if the transmission is not working properly, i.e., if the transmission slips or shifts slowly or if you notice some sign of fluid leakage.

Automatic transmission fluid expands when warmed. To obtain an accurate fluid check, drive the vehicle until it is at normal operating temperature (approximately

19 mi (30 km)). Verify that the transmission fluid temperature gauge, located on the instrument cluster, is within normal range.

    Drive the vehicle 19 mi (30 km)until it reaches normal operating temperature.
    Park the vehicle on a level surface and engage the parking brake.
    With the engine running, parking brake engaged and your foot on the brake pedal, move the gearshift lever through all of the gear ranges. Allow sufficient time for each gear to engage.
    Latch the gearshift lever in P and leave the engine running.
    Remove the dipstick, wiping it clean with a clean, dry lint free rag. If necessary, refer to the Under Hood Overview in this chapter for the location of the dipstick.

346

    Install the dipstick making sure it is fully seated in the filler tube.
    Remove the dipstick and inspect the fluid level. The fluid should be in the designated area for normal operating temperature or ambient temperature.

Fluid levels above the safe range may result in transmission failure. An overfill condition of transmission fluid may cause shift and engagement concerns, and possible damage.

High fluid levels can be caused by an overheating condition.

Note: Use of a non-approved automatic transmission fluid may cause internal transmission component damage.

Before adding any fluid, make sure the correct type is used. The type of fluid used is normally indicated on:

E163746

If an overfill occurs, excess fluid should be removed by a qualified technician.

Note: An overfill condition of transmission fluid may cause shift and engagement concerns, and possible damage.

348

Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.

CHECK (If Equipped)

Do not use any fluid other than the recommended brake fluid as this will reduce brake efficiency. Use of

incorrect fluid could result in the loss of vehicle control, serious personal injury or death.

Only use brake fluid from a sealed container. Contamination with dirt, water, petroleum products or other

materials may result in brake system damage or failure. Failure to adhere to this warning could result in the loss of vehicle control, serious personal injury or death.

Do not allow the fluid to touch your skin or eyes. If this happens, rinse the affected areas immediately with

plenty of water and contact your physician.

A fluid level between the MAX and MIN lines is within the normal operating range and there is no need

to add fluid. A fluid level not in the normal operating range could compromise the performance of the system. Have your vehicle checked immediately.

E164246

    Clean the filler plug.
    Remove the filler plug and inspect the fluid level.
    Add only enough fluid through the filler opening so that the fluid level is at the bottom of the opening.

Only use fluid that meets Ford specifications. See Capacities and Specifications (page 420).

349

E170684

To avoid fluid contamination, the reservoir cap must remain in place and fully tight, unless you are adding fluid.

Only use fluid that meets Ford specifications. See Capacities and Specifications (page 420).

Check the power steering fluid. See Scheduled Maintenance (page 581). If adding fluid is necessary, use only MERCON LV ATF

Check the fluid level when it is at ambient temperature.

    Check the fluid level in the reservoir. It should be between the MIN and MAX range. Do not add fluid if the level is within this range.
    If the fluid level is low, add fluid to bring the fluid level up to between the MIN and MAX range.
    Switch the engine on.
    While the engine idles, turn the steering wheel left and right several times.
    Switch the engine off.
    Recheck the fluid level in the reservoir. Do not add fluid if the level is between the MIN and MAX range.
    If the fluid is low, add fluid in small amounts, continuously checking the level until it is between the MIN and MAX range. For proper fluid type, See Capacities and Specifications (page 420). Be sure to put the cap back on the reservoir.

If you operate your vehicle in temperatures below 40°F (5°C), use washer fluid with antifreeze

protection. Failure to use washer fluid with antifreeze protection in cold weather could result in impaired windshield vision and increase the risk of injury or accident.

Add fluid to fill the reservoir if the level is low. Only use a washer fluid that meets Ford specifications. See Capacities and Specifications (page 420).

State or local regulations on volatile organic compounds may restrict the use of methanol, a common windshield washer antifreeze additive. Washer fluids containing non-methanol antifreeze agents should be used only if they provide cold weather protection without damaging the vehicle’s paint finish, wiper blades or washer system.

350

Do not dispose of fuel in the household refuse or the public sewage system. Use an authorized

waste disposal facility.

Your vehicle has a diesel fuel conditioner module. The module is mounted between the outboard side of the fuel tank and the frame rail.

Note: The module is at the front of the fuel tank or at the front of the aft-axle fuel tank on some models.

You should drain water from the module assembly whenever the warning light illuminates or a

message appears in the information display advising you to drain the water separator. This occurs when approximately

6.76 fl oz (200 ml) of water accumulates in the module. If you allow the water level to exceed this level, the water may pass through to the engine and may cause fuel injection equipment damage.

    Tighten the drain plug, turn it clockwise until it stops and you feel a strong resistance. Do not use any tools to tighten the drain plug.

Your vehicle is equipped with a lifetime fuel filter that is integrated with the fuel tank. Regular maintenance or replacement is not needed.

352

Batteries normally produce explosive gases which can cause personal injury. Therefore, do not allow

flames, sparks or lighted substances to come near the battery. When working near the battery, always shield your face and protect your eyes. Always provide correct ventilation.

When lifting a plastic-cased battery, excessive pressure on the end walls could cause acid to flow through the

vent caps, resulting in personal injury and damage to the vehicle or battery. Lift the battery with a battery carrier or with your hands on opposite corners.

Keep batteries out of reach of children. Batteries contain sulfuric acid. Avoid contact with skin, eyes or

clothing. Shield your eyes when working near the battery to protect against possible splashing of acid solution. In case of acid contact with skin or eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical attention. If acid is swallowed, call a physician immediately.

Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after

handling.

This vehicle may have more than one battery. Removing the battery cables from only one battery does not

disconnect your vehicle electrical system. Make sure you disconnect the battery cables from all batteries when disconnecting power. Failure to do so may cause serious personal injury or property damage.

Your vehicle is fitted with a Motorcraft maintenance-free battery which normally does not require additional water.

When a battery replacement is required, you must use a recommended replacement battery that matches the electrical requirements of the vehicle.

Note: After cleaning or replacing the battery, make sure you reinstall the battery cover or shield.

Note: If you add electrical accessories or components to the vehicle, it may adversely affect the low voltage battery performance and durability. This may also affect the performance of other electrical systems in the vehicle.

For longer, trouble-free operation, keep the top of the battery clean and dry.

If you see any corrosion on the battery or terminals, remove the cables from the terminals and clean with a wire brush. You can neutralize the acid with a solution of baking soda and water.

Because your vehicle’s engine is electronically controlled by a computer, some control conditions are maintained by power from the battery. When the battery is disconnected or a new battery is installed, the engine must relearn its idle and fuel trim strategy for optimum driveability and performance. Flexible fuel vehicles (FFV) must also relearn the ethanol content of the fuel for optimum driveability and performance.

To restore the settings, do the following:

    Apply the parking brake.
    Shift into park (P) or neutral (N).
    Switch off all accessories.
    Press the brake pedal and start your vehicle.

353

    Run the engine until it reaches normal operating temperature. While the engine is warming up, complete the following: Reset the clock. Reset the power windows bounce-back feature. See Windows and Mirrors (page 98). Reset the radio station presets. See Audio System (page 445).
    Allow the engine to idle for at least one minute.
    Drive the vehicle at least 10 mi (16 km) to completely relearn the idle trim and fuel trim strategy.

Note: If you do not allow the engine to relearn the idle and fuel trim strategy, the idle quality of your vehicle may be adversely affected until the engine computer eventually relearns the idle trim and fuel trim strategy.

Note: For flexible fuel vehicles, if you are operating on E85, you may experience poor starts or an inability to start the engine and driveability problems until the fuel trim and ethanol content have been relearned.

Make sure that you dispose of old batteries in an environmentally friendly way. Seek advice from your local authority about recycling old batteries.

If storing your vehicle for more than 30 days without recharging the battery, we recommend that you disconnect the battery cables to maintain battery charge for quick starting.

Battery Management System (If Equipped)

The battery management system monitors battery conditions and takes actions to extend battery life. If excessive battery drain is detected, the system temporarily disables some electrical systems to protect the battery.

Systems included are:

    Heated rear window.
    Heated seats.
    Climate control.
    Heated steering wheel.
    Audio unit.
    Navigation system.

A message may appear in the information displays to alert you that battery protection actions are active. These messages are only for notification that an action is taking place, and not intended to indicate an electrical problem or that the battery requires replacement.

After battery replacement, or in some cases after charging the battery with an external charger, the battery management system requires eight hours of vehicle sleep time to relearn the battery state of charge. During this time your vehicle must remain fully locked with the ignition switched off.

Note: Prior to relearning the battery state of charge, the battery management system may temporarily disable some electrical systems.

To make sure the battery management system works correctly, do not connect an electrical device ground connection directly to the battery negative post. This can cause inaccurate measurements of the battery condition and potential incorrect system operation.

Note: If you add electrical accessories or components to the vehicle, it may adversely affect battery performance and durability. This may also affect the performance of other electrical systems in the vehicle.

The air filter restriction gauge is in the upper housing of the air filter assembly.

Check the air filter restriction gauge whenever you open the hood to carry out general engine maintenance or at least every 7,500 mi (12,000 km). If you operate your vehicle in extremely dusty conditions, check the gauge at least every 500 mi (800 km) or two weeks, whichever occurs first. Change the air filter element when the restriction gauge reads near the change filter line and the gauge is yellow. Allowing the restriction gauge to reach maximum affects engine performance and fuel economy.

364

Operating your vehicle in heavy snowfall or extreme rain conditions may allow excessive amounts of snow or water into the air intake system. This could restrict air flow and cause the engine to lose power or shut down.

After installing a new air filter element, you must reset the gauge by pressing the reset button.

After operating your vehicle during heavy snowfall or extreme rain, do the following:

    Snow: At the earliest opportunity, open the hood and clear any snow and ice from the air filter housing inlet and reset the air filter restriction gauge.
    Extreme rain: The air filter element dries out after approximately 15–30 minutes of driving at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge.

Note: Do not remove the foam filter.

Do not dispose of fuel in the household refuse or the public sewage system. Use an authorized

waste disposal facility.

Your vehicle has two fuel filters. The first filter mounts on top of the engine on the left-hand side. The second filter is inside the diesel fuel conditioner module. The module is attached to the fuel tank in different locations depending on the configuration of your truck. See table below for configurations.

Note: The module is at the front of the fuel tank or at the front of the aft-axle fuel tank on some models.

Regular fuel filter changes are an important part of engine maintenance; failing to keep with the scheduled maintenance could lead to engine performance issues and fuel injection system damage. See Scheduled Maintenance (page 581).

Use only recommended service parts conforming to specifications. See Motorcraft Parts (page 422).

Note: Using fuel that has high levels of impurities may require more frequent filter replacements than the service interval specifies.
