 CHECKING THE ENGINE OIL LEVEL

1. Make sure that your vehicle is on level ground.

1. Check the oil level before starting the engine, or switch the engine off after warm up and wait 15 minutes for the oil to drain into the oil pan.

Note:   Checking the oil level too soon could result in an inaccurate reading.

1. Remove the dipstick and wipe it with a clean, lint-free cloth.

1. Reinstall the dipstick and make sure it is fully seated.

1. Remove the dipstick again to check the oil level.

Note:   Read both sides of the dipstick and use the lowest oil level as the correct reading.

Note:   If the oil level is between the maximum and minimum marks, the oil level is acceptable.Do not add oil.

1. If the oil level is at the minimum mark, immediately add oil.

1. Reinstall the dipstick. Make sure it is fully seated.

Note:   The oil consumption of new engines reaches its normal level after approximately 3,000 mi (5,000 km).

Note:   Increases in oil level can occur from frequent short trips that do not allow the engine to get to operating temperature, as well as frequent idling or low speed driving for long periods of time.

Note:   If oil levels are continuously noted above the maximum mark, have your vehicle checked as soon as possible.

ADDING ENGINE OIL

WARNING:  Do not remove the filler cap when the engine is running.    WARNING:  Do not add engine oil when the engine is hot. Failure to follow this instruction could result in personal injury.

 

Do not use supplemental engine oil additives because they are unnecessary and could lead to engine damage that the vehicle warranty may not cover.

1. Clean the area surrounding the engine oil filler cap before you remove it.

1. Remove the engine oil filler cap.

1. Add engine oil that meets our specifications.See   Capacities and Specifications. 

1. Reinstall the engine oil filler cap.Turn it clockwise until you feel a strong resistance.

ENGINE OIL CAPACITY AND SPECIFICATION

For filling information, please refer to the Capacities and Specifications section of your owner's manual.  See   Capacities and Specifications. 

CHECKING THE COOLANT

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. 

Note:   Make sure that the coolant level is between the minimum and maximum marks on the coolant reservoir.

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

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

Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -29 °F (-34 °C) and -35 °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.

ADDING COOLANT

WARNING:  Keep your hands and clothing clear of the cooling fan.    WARNING:  Do not remove the coolant reservoir cap when the engine is on or the cooling system is hot. Wait 10 minutes for the cooling system to cool down. Cover the coolant reservoir cap with a thick cloth to prevent the possibility of scalding and slowly remove the cap. Failure to follow this instruction could result in personal injury.    WARNING:  Do not add coolant when the vehicle is on or the cooling system is hot. Failure to follow this instruction could result in personal injury.    WARNING:  Do not add coolant further than the MAX mark.    WARNING:  Do not put coolant in the windshield washer reservoir. If sprayed on the windshield, coolant could make it difficult to see through the windshield.    WARNING:  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.

 

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.

Note:   Automotive fluids are not interchangeable.

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.  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 could void the vehicle Warranty.

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

To top up the coolant level do the following:

1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.

1. Add enough prediluted coolant to reach the correct level.

Note:   We do not recommend the use of recycled coolant.

1. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the hard stop.

1. Check the coolant level in the coolant reservoir the next few times you drive your vehicle. If necessary, repeat step 2.

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.

In case of emergency, you can add a large amount of water without engine coolant in order to reach a vehicle service location. Service your vehicle as soon as possible.

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

Do not use the following as a coolant substitute, as they can cause engine damage from overheating or freezing:

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

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

SEVERE CLIMATES

If you drive in extremely cold climates, you may need to increase the coolant concentration above 50%.

Note:   A coolant concentration of 60% provides improved freeze point protection. Coolant concentrations above 60% decrease the overheat protection characteristics of the coolant and could cause engine damage.

If you drive in extremely hot climates, you may need to decrease the coolant concentration to 40%.

Note:   A coolant concentration of 40% provides improved overheat protection. Coolant concentrations below 40% decrease the overheat and corrosion protection characteristics of the coolant and could cause engine damage.

COOLANT CHANGE

WARNING:  Do not dispose of coolant in the household refuse or the public sewage system. Use an authorized waste disposal facility.

 

Change the coolant at specific mileage intervals. Refer to the scheduled maintenance information.   See   Normal Scheduled Maintenance. 

Note:   Dispose of used coolant in the appropriate manner.

Follow your community's regulations and standards for recycling and disposing of automotive fluids.

FAIL-SAFE COOLING

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.

HOW FAIL-SAFE COOLING WORKS

WARNING:  If you continue to drive your vehicle when the engine is overheating, the engine could stop without warning. Failure to follow this instruction could result in the loss of control of your vehicle.

 

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.

WHEN FAIL-SAFE MODE IS ACTIVATED

WARNING:  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.    WARNING:  Do not remove the coolant reservoir cap when the engine is on or the cooling system is hot. Wait 10 minutes for the cooling system to cool down. Cover the coolant reservoir cap with a thick cloth to prevent the possibility of scalding and slowly remove the cap. Failure to follow this instruction could result in personal injury.

 

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 could operate poorly.

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

1. Pull off the road as soon as safely possible and switch the engine off.

1. If you are a member of a roadside assistance program, we recommend that you contact your roadside assistance service provider.

1. If this is not possible, wait for a short period of time for the engine to cool.

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

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

Note:   If you continue to drive your vehicle in fail-safe mode without repairing it, you will damage your engine.

ENGINE COOLANT TEMPERATURE MANAGEMENT (IF EQUIPPED)

WARNING:  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 a higher 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 stop your vehicle.You can continue to drive.

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:

1. Stop your vehicle as soon as it is safe to do so. Fully apply the parking brake, shift into park (P) or neutral (N).

1. Leave the engine running until the coolant temperature gauge needle returns to the normal position.If the temperature does not drop after several minutes, follow the remaining steps.

1. Switch the engine off and wait for it to cool. Check the coolant level.

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

1. If the coolant level is normal, restart the engine and continue.

CHANGING THE ENGINE AIR 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.

 

Change the engine air filter element at the proper intervals.   See   Normal Scheduled Maintenance. 

When changing the engine air filter, use only the air filter element listed.   See   Motorcraft Parts. 

Note:   Failure to use the correct air filter element may result in severe engine damage.Resulting component damage may not be covered by the vehicle Warranty.

Note:   When servicing the air cleaner, do not allow foreign material to enter the air induction system.

1. Release the two clamps that secure the cover to the air filter housing. Push the air filter cover toward the front of the vehicle and up slightly to release it.

1. Remove the air filter element from the air filter housing.

1. Install the new air filter element.

1. Replace the air filter housing cover and secure all the clamps. Be careful not to crimp the filter element edges between the air filter housing and cover, and make sure that you properly align the tabs on the edge into the slots.

CHANGING THE FUEL FILTER

Your vehicle has a lifetime fuel filter that integrates with the fuel tank. It does not need regular maintenance or replacement.

CHANGING THE 12V BATTERY

WARNING:  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.    WARNING:  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.    WARNING:  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.    WARNING:  Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash your hands after handling.    WARNING:  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.    WARNING:  For vehicles with Auto-Start-Stop the battery requirement is different. You must replace the battery with one of exactly the same specification.

 

 The battery is in the engine compartment.See   Under Hood Overview. 

 Your vehicle has a maintenance-free battery. It does not require additional water during service.

If the vehicle battery has a cover and vent hose, make sure you correctly install it after cleaning or replacing the battery.

For longer, trouble-free operation, keep the top of the battery clean and dry and the battery cables tightly fastened to the battery terminals. If any corrosion is present 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.

We recommend that you disconnect the negative battery cable terminal from the battery if you plan to store your vehicle for an extended period.

Note:   If you only disconnect the negative battery cable terminal, make sure it is isolated or placed away from the battery terminal to avoid unintended connection or arcing.

If you replace the battery make sure it matches the electrical requirements of your vehicle.

If you disconnect or replace the battery and your vehicle has an automatic transmission, it must relearn its adaptive strategy. Because of this, the transmission may shift firmly when first driven. This is normal operation while the transmission fully updates its operation to optimum shift feel.

BATTERY SENSOR RESET

When you install a new battery, reset the battery sensor by doing the following:

1. Switch the ignition on, and leave the engine off.

Note:   Complete Steps 2 and 3 within 10 seconds.

1. Flash the high beam headlamps five times, ending with the high beams off.

1. Press and release the brake pedal three times.

The battery warning lamp flashes three times to confirm that the reset is successful.

BATTERY MANAGEMENT SYSTEM (IF EQUIPPED)

The 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 display to alert you that battery protection actions are active. This message is 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.

ELECTRICAL ACCESSORY INSTALLATION

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.

REMOVE AND REINSTALL THE BATTERY

Install a battery approved for use by our specifications.   See   Capacities and Specifications. 

To disconnect or remove the battery, do the following:

1. Apply the parking brake and switch the ignition off.

1. Switch all electrical equipment off, for example lights and radio.

1. Wait a minimum of two minutes before disconnecting the battery.

Note:   The engine management system has a power hold function and remains powered for a period of time after you switch the ignition off. This is to allow the system to store diagnostic and adaptive tables. Disconnecting the battery without waiting can cause damage not covered by the vehicle warranty.

1. Disconnect the negative battery cable terminal.

1. Disconnect the positive battery cable terminal.

1. Remove the battery securing clamp.

1. Remove the battery.

1. To install, reverse the removal procedure.

Note:   Before reconnecting the battery, make sure the ignition remains switched off.

If you disconnect or replace the vehicle battery, you must reset the following features:

• Window bounce-back.   See   Opening and Closing the Windows. 
• Clock Settings.
• Pre-set radio stations.

BATTERY DISPOSAL

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

 ADJUSTING THE HEADLAMPS

VERTICAL AIM ADJUSTMENT

The headlamps on your vehicle are properly aimed at the assembly plant. If your vehicle has been in an accident, contact an authorized dealer to check and realign your headlamps.

HEADLAMP AIMING TARGET

A8 feet (2.4 m). BCenter height of lamp to ground. C25 feet (7.6 m). DHorizontal reference line.

1. Park your vehicle directly in front of a wall or screen on a level surface, approximately 25 ft (7.6 m) away.

1. Measure the height from the center of your headlamp, indicated by a 3 millimeter circle on the lens, to the ground and mark an 8 ft (2.4 m) horizontal reference line on the vertical wall or screen at this height, a piece of masking tape works well.

1. Switch on the low beam headlamps to illuminate the wall or screen and open the hood. Cover one of the headlamps so no light hits the wall.

1. On the wall or screen, observe a light pattern with a distinct horizontal edge toward the right. If this edge is not at the horizontal reference line, adjust the beam so the edge is at the same height as the horizontal reference line.

1. Locate the vertical adjuster on each headlamp. Use a #2 Phillips screwdriver to turn the adjuster either counterclockwise or clockwise in order to adjust the vertical aim of the headlamp.

1. Repeat Steps 3 through 7 to adjust the other headlamp.

1. Close the hood and turn off the lamps.
