WINDSHIELD WASHER FLUID  
Add fluid to fill the reservoir if the  
level is low. In very cold weather, do  
not fill the reservoir completely.  
Only use a washer fluid that meets Ford specification WSB-M8B16–A2.  
Do not use any special washer fluid such as windshield water repellent  
type fluid or bug wash. They may cause squeaking, chatter noise,  
streaking and smearing. Refer to the Maintenance product  
specifications and capacities section in this chapter.  
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.  
WARNING: 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.  
Do not put washer fluid in the engine coolant reservoir. Washer  
fluid placed in the cooling system may harm engine and cooling  
system components.  
Checking and adding washer fluid for the liftgate  
Washer fluid for the liftgate is supplied by the same reservoir as the  
windshield.

Poor wiper quality can be improved  
by cleaning the wiper blades and  
the windshield. Refer to Windows  
and wiper blades in the Cleaning chapter.  
To prolong the life of the wiper blades, it is highly recommended to  
scrape off the ice on the windshield before turning on the wipers. The  
layer of ice has many sharp edges and can damage the micro edge of the  
wiper rubber element.  
Changing the rear window wiper blade  
To replace the rear wiper blade:  
1. Pull the wiper arm as far away from the glass as possible. Do not use  
excessive force because it can break the wiper arm. Hold it there until  
the next step.  
2. Grasp the wiper blade and rotate  
it away from the wiper arm using  
moderate force until it disengages  
from the wiper arm.  
3. Once the wiper blade is loose,  
slide it away from the wiper arm.

Maintenance and Specifications  
BATTERY  
Your vehicle is equipped with a  
Motorcraftmaintenance-free  
battery which normally does not  
require additional water during its  
life of service.  
If your battery has a cover/shield, make sure it is reinstalled  
after the battery has been cleaned or replaced.  
For longer, trouble-free operation, keep the top of the battery clean and  
dry. Also, make certain the battery cables are always tightly fastened to  
the battery terminals.  
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.  
It is recommended that the negative battery cable terminal be  
disconnected from the battery if you plan to store your vehicle for an  
extended period of time. This will minimize the discharge of your battery  
during storage.  
Note: Electrical or electronic accessories or components added to  
the vehicle by the dealer or the owner may adversely affect  
battery performance and durability.  
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  
proper 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/or damage to the vehicle or  
battery. Lift the battery with a battery carrier or with your hands on  
opposite corners.  
361  
2010 Explorer (exp)  
Owners Guide, 2nd Printing

Maintenance and Specifications  
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. Wash hands after handling.  
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. To begin this process:  
1. With the vehicle at a complete stop, set the parking brake.  
2. Put the gearshift lever in P (Park), turn off all accessories and start  
the engine.  
3. Run the engine until it reaches normal operating temperature.  
4. Allow the engine to idle for at least one minute.  
5. Turn the A/C on and allow the engine to idle for at least one minute.  
6. Drive the vehicle to complete the relearning process.  
The vehicle may need to be driven to relearn the idle and fuel trim  
strategy.  
If you do not allow the engine to relearn its idle trim, the idle  
quality of your vehicle may be adversely affected until the idle  
trim is eventually relearned.  
When the battery is disconnected or a new battery installed, the  
transmission must relearn its adaptive strategy. As a result of this, the  
transmission may shift firmly. This operation is considered normal and  
will not affect function or durability of the transmission. Over time the  
adaptive learning process will fully update transmission operation to its  
optimum shift feel.  
If the battery has been disconnected or a new battery has been installed,  
the clock and the preset radio stations must be reset once the battery is  
reconnected.

standards for disposal. Call your  
local authorized recycling center  
to find out more about recycling  
automotive batteries.  
RECYCLE  
ENGINE COOLANT  
Checking engine coolant  
The concentration and level of engine coolant should be checked at the  
intervals listed in scheduled maintenance information. The coolant  
concentration should be maintained at 50/50 coolant and distilled water,  
which equates to a freeze point of -34°F (-36°C). Coolant concentration  
testing is possible with a hydrometer or antifreeze tester. The level of  
coolant should be maintained at the FULL COLD level in the coolant  
reservoir. If the level falls below, add coolant per the instructions in the  
Adding engine coolant section.  
Your vehicle was factory-filled with a 50/50 engine coolant and water  
concentration. If the concentration of coolant falls below 40% or above  
60%, the engine parts could become damaged or not work properly. A  
50/50 mixture of coolant and water provides the following:  
Freeze protection down to -34°F (-36°C).  
Boiling protection up to 265°F (129°C).  
Protection against rust and other forms of corrosion.  
Enables calibrated gauges to work properly.  
When the engine is cold, check the level of the engine coolant in the  
reservoir.

Maintenance and Specifications  
4.0L V6 engine  
4.6L V8 engine  
The engine coolant should be at the FULL COLD level or within the  
COLD FILL RANGE as listed on the engine coolant reservoir  
(depending upon application).  
Refer to scheduled maintenance information for service interval  
schedules.  
If the engine coolant has not been checked at the recommended interval,  
the engine coolant reservoir may become low or empty. If the reservoir is  
low or empty, add engine coolant to the reservoir. Refer to Adding  
engine coolant in this chapter.  
Note: Automotive fluids are not interchangeable; do not use engine  
coolant/antifreeze or windshield washer fluid outside of its specified  
function and vehicle location.  
364

Maintenance and Specifications  
Adding engine coolant  
When adding coolant, make sure it is a 50/50 mixture of engine coolant  
and distilled water. Add the mixture to the coolant reservoir, when the  
engine is cool, until the appropriate fill level is obtained. If coolant is  
filled to the COLD FILL RANGE or FULL COLD level when the engine is  
not cool, the system will remain underfilled.  
WARNING: Do not add engine coolant when the engine is hot.  
Steam and scalding liquids released from a hot cooling system  
can burn you badly. Also, you can be burned if you spill coolant on hot  
engine parts.  
WARNING: Do not put engine coolant in the windshield washer  
fluid container. If sprayed on the windshield, engine coolant  
could make it difficult to see through the windshield.  
DO NOT MIX different colors or types of coolant in your vehicle.  
Make sure the correct coolant is used. DO NOT MIX recycled coolant  
and conventional coolant together in the vehicle. Mixing of engine  
coolants may harm your engine’s cooling system. The use of an  
improper coolant may harm engine and cooling system components  
and may void the warranty. Refer to Maintenance product  
specifications and capacities in this chapter.  
Note: Do not use stop leak pellets or cooling system sealants/additives  
as they can cause damage to the engine cooling and/or heating systems.  
This damage would not be covered under your vehicle’s warranty.  
A large amount of water without engine coolant may be added, in case  
of emergency, to reach a vehicle service location. In this instance, the  
cooling system must be drained and refilled with a 50/50 mixture of  
engine coolant and distilled water as soon as possible. Water alone  
(without engine coolant) can cause engine damage from corrosion,  
overheating or freezing.  
Do not use alcohol, methanol, brine or any engine coolants  
mixed with alcohol or methanol antifreeze (coolant). 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 engine  
coolant.

Maintenance and Specifications  
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 the proper mixture of coolant and  
water to the FULL COLD level. For all other 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 of a vehicle with  
an overflow system, follow these steps to add engine coolant.  
WARNING: 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 the cap is loosened slightly.  
Add the proper mixture of coolant and water to the cooling system by  
following these steps:  
1. Before you begin, turn the engine off and let it cool.  
2. When the engine is cool, wrap a thick cloth around the coolant  
pressure relief cap on the coolant reservoir (a translucent plastic bottle).  
Slowly turn cap counterclockwise (left) until pressure begins to release.  
3. Step back while the pressure releases.  
4. When you are sure that all the pressure has been released, use the  
cloth to turn it counterclockwise and remove the cap.  
5. Fill the coolant reservoir slowly with the proper coolant mixture, to  
within the COLD FILL RANGE or the FULL COLD level on the reservoir.  
If you removed the radiator cap in an overflow system, fill the radiator  
until the coolant is visible and radiator is almost full.  
6. Replace the cap. Turn until tightly installed. Cap must be tightly  
installed to prevent coolant loss.  
After any coolant has been added, check the coolant concentration (refer  
to Checking engine coolant). If the concentration is not 50/50  
(protection to –34°F/–36°C), drain some coolant and adjust the  
concentration. It may take several drains and additions to obtain a 50/50  
coolant concentration.  
Whenever coolant has been added, the coolant level in the coolant  
reservoir should be checked the next few times you drive the vehicle. If  
necessary, add enough 50/50 concentration of engine coolant and  
distilled water to bring the liquid level to the proper level.  
366  
2010 Explorer (exp)  
Owners Guide, 2nd Printing  
USA (fus)  
Maintenance and Specifications  
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per  
month, have your authorized dealer check the engine cooling system.  
Your cooling system may have a leak. Operating an engine with a low  
level of coolant can result in engine overheating and possible engine  
damage.  
Recycled engine coolant  
Ford Motor Company does NOT recommend the use of recycled engine  
coolant since a Ford-approved recycling process is not yet available.  
Used engine coolant should be disposed of in an appropriate  
manner. Follow your community’s regulations and standards for recycling  
and disposing of automotive fluids.  
Coolant refill capacity  
To find out how much fluid your vehicle’s cooling system can hold, refer  
to Maintenance product specifications and capacities in this chapter.  
Fill your engine coolant reservoir as outlined in Adding engine coolant  
in this section.  
Severe climates  
If you drive in extremely cold climates (less than –34°F [–36°C]):  
It may be necessary to increase the coolant concentration  
above 50%.  
NEVER increase the coolant concentration above 60%.  
Increased engine coolant concentrations above 60% will  
decrease the overheat protection characteristics of the engine  
coolant and may cause engine damage.  
Refer to the chart on the coolant container to ensure the  
coolant concentration in your vehicle will provide adequate  
freeze protection at the temperatures in which you drive in the  
winter months.  
If you drive in extremely hot climates:  
It is still necessary to maintain the coolant concentration  
above 40%.  
NEVER decrease the coolant concentration below 40%.  
Decreased engine coolant concentrations below 40% will  
decrease the corrosion/freeze protection characteristics of the  
engine coolant and may cause engine damage.

Maintenance and Specifications  
Refer to the chart on the coolant container to ensure the  
coolant concentration in your vehicle will provide adequate  
protection at the temperatures in which you drive.  
Vehicles driven year-round in non-extreme climates should use a 50/50  
mixture of engine coolant and distilled water for optimum cooling system  
and engine protection.  
What you should know about fail-safe cooling  
(4.6L V8 engine only)  
If the engine coolant supply is depleted, this feature allows the vehicle to  
be driven temporarily before incremental component damage is incurred.  
The “fail-safe” distance depends on ambient temperatures, vehicle load  
and terrain.  
Fail-safe cooling and engine oil overheat mode (4.6L V8 only)  
If the engine coolant and/or engine oil overheat, the vehicle’s fail-safe  
modes will reduce engine power to limit engine damage, even with a  
total loss of coolant. The vehicle’s range and/or speed will be reduced,  
depending on vehicle load, terrain, and outside temperatures.  
The instrument cluster provides warnings for each mode.  
Fail-safe cooling mode: The  
(service engine  
(engine oil pressure), and (engine coolant  
soon),  
temperature) indicators will be on.  
Along with these warning indicators, the engine coolant temperature  
gauge will read in the H (Hot) area.  
If the engine coolant reaches even hotter temperatures, fail-safe  
cooling mode limits engine power more and disables air conditioning.  
The engine will switch to alternating cylinder operation to help cool  
the engine. The engine will run rough in this mode.  
If continued operation increases the engine coolant temperature to a  
critical range, the engine will shut down. Steering and braking effort  
will increase. Once engine coolant temperature cools, the engine can  
be restarted.  
Engine oil overheat mode: The  
(engine coolant temperature)  
indicator will be on. The instrument cluster has no separate oil  
temperature indicator.  
368  
2010 Explorer (exp)  
Owners Guide, 2nd Printing  
USA (fus)  
Maintenance and Specifications  
Along with the  
(engine coolant temperature) indicator, the engine  
coolant temperature gauge will read in the H (Hot) area.  
Oil overheat can be triggered in severe driving conditions, such as  
towing heavy loads over mountainous terrain in extreme hot  
temperatures. As oil temperature increases, engine and vehicle speed  
will be limited. The transmission will also shift differently.  
When the engine oil has cooled, the vehicle will perform normally.  
When fail-safe cooling mode is activated  
You have limited engine power when in the fail-safe mode, so drive the  
vehicle with caution. Remember that the engine is capable of completely  
shutting down automatically to prevent engine damage, therefore:  
1. Pull off the road as soon as safely possible and turn off the engine.  
2. Arrange for the vehicle to be taken to an authorized dealer.  
3. If this is not possible, wait approximately 15 minutes for the engine to  
cool.  
4. Check the coolant level and replenish if low. Look for coolant leakage  
in the engine compartment and under the vehicle.  
WARNING: Never remove the coolant reservoir cap while the  
engine is running or hot.  
5. Restart the engine and take your vehicle to an authorized dealer.  
Driving the vehicle without repairing the engine problem  
increases the chance of engine damage. Take your vehicle to an  
authorized dealer as soon as possible.  
FUEL FILTER  
For fuel filter replacement, see your authorized dealer. Refer to  
scheduled maintenance information for the appropriate intervals for  
changing the fuel filter.  
Replace the fuel filter with an authorized Motorcraftpart. The  
customer warranty may be void for any damage to the fuel system  
if an authorized Motorcraftfuel filter is not used.

WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS  
Important safety precautions  
WARNING: Do not overfill the fuel tank. The pressure in an  
overfilled tank may cause leakage and lead to fuel spray and fire.  
WARNING: The fuel system may be under pressure. If you hear  
a hissing sound near the fuel filler door (Easy Fuel™ “no cap”  
fuel system), do not refuel until the sound stops. Otherwise, fuel may  
spray out, which could cause serious personal injury.  
WARNING: Automotive fuels can cause serious injury or death  
if misused or mishandled.  
WARNING: Gasoline may contain benzene, which is a  
cancer-causing agent.  
Observe the following guidelines when handling automotive fuel:  
Extinguish all smoking materials  
and any open flames before  
refueling your vehicle.  
Always turn off the vehicle before  
refueling.  
Automotive fuels can be harmful  
or fatal if swallowed. Fuel such as gasoline is highly toxic and if  
swallowed can cause death or permanent injury. If fuel is swallowed,  
call a physician immediately, even if no symptoms are immediately  
apparent. The toxic effects of fuel may not be visible for hours.  
Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind  
can lead to eye and respiratory tract irritation. In severe cases,  
excessive or prolonged breathing of fuel vapor can cause serious  
illness and permanent injury.  
Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,  
remove contact lenses (if worn), flush with water for 15 minutes and  
seek medical attention. Failure to seek proper medical attention could  
lead to permanent injury.

Maintenance and Specifications  
Fuels can also be harmful if absorbed through the skin. If fuel is  
splashed on the skin and/or clothing, promptly remove contaminated  
clothing and wash skin thoroughly with soap and water. Repeated or  
prolonged skin contact with fuel liquid or vapor causes skin irritation.  
Be particularly careful if you are taking “Antabuse” or other forms of  
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,  
or skin contact could cause an adverse reaction. In sensitive  
individuals, serious personal injury or sickness may result. If fuel is  
splashed on the skin, promptly wash skin thoroughly with soap and  
water. Consult a physician immediately if you experience an adverse  
reaction.  
WARNING: When refueling always shut the engine off and  
never allow sparks or open flames near the filler neck. Never  
smoke while refueling. Fuel vapor is extremely hazardous under certain  
conditions. Care should be taken to avoid inhaling excess fumes.  
WARNING: The flow of fuel through a fuel pump nozzle can  
produce static electricity, which can cause a fire if fuel is  
pumped into an ungrounded fuel container.  
Refueling  
WARNING: Fuel vapor burns violently and a fuel fire can cause  
severe injuries. To help avoid injuries to you and others:  
Read and follow all the instructions on the pump island;  
Turn off your engine when you are refueling;  
Do not smoke if you are near fuel or refueling your vehicle;  
Keep sparks, flames and smoking materials away from fuel;  
Stay outside your vehicle and do not leave the fuel pump unattended  
when refueling your vehicle — this is against the law in some places;  
Keep children away from the fuel pump; never let children pump  
fuel.  
Use the following guidelines to avoid electrostatic charge build-up when  
filling an ungrounded fuel container:  
Place approved fuel container on the ground.  
DO NOT fill a fuel container while it is in the vehicle (including the  
cargo area).

Keep the fuel pump nozzle in contact with the fuel container while  
filling.  
DO NOT use a device that would hold the fuel pump handle in the fill  
position.  
Easy Fuel™ “no cap” fuel system  
Your fuel tank is equipped with an Easy Fuel™ “no cap” fuel filler  
system. This allows you to simply open the fuel filler door and insert the  
fuel filler nozzle into the fuel system. The Easy Fuel™ system is  
self-sealing and protected against dust, dirt, water and snow/ice.  
When fueling your vehicle:  
1. Turn the engine off.  
2. Open the fuel filler door.  
3. Slowly insert the fuel filler nozzle fully into the fuel system. Pump fuel  
as normal.  
4. After you are done pumping fuel, slowly remove the fuel filler  
nozzle—allow about five seconds after pumping fuel before removing the  
fuel filler nozzle. This allows residual fuel to drain back into the fuel tank  
and not spill onto the vehicle.  
Note: A fuel spillage concern may occur if overfilling the fuel tank. Do  
not overfill the tank to the point that the fuel is able to bypass the fuel  
filler nozzle. The overfilled fuel may run down the drain located within  
the fuel filler housing and to the ground.  
If the Check Fuel Fill Inlet lamp or Check Fuel Fill Inlet message comes  
on, the fuel fill inlet may not have properly closed. The inlet may have  
stuck open or debris may be preventing the inlet from fully closing. At  
the next opportunity, safely pull off the road, turn off the engine, open  
the fuel filler door and remove any visible debris from the fuel fill  
opening. Insert either the fuel fill nozzle or the fuel fill funnel (see  
Refilling with a portable fuel container for funnel location) provided  
with the vehicle several times to dislodge any debris and/or allow the  
inlet to close properly. If this action corrects the problem, the Check  
Fuel Fill Inlet lamp or Check Fuel Fill Inlet message may not reset  
immediately. It may take several driving cycles for the Check Fuel Fill  
Inlet lamp or Check Fuel Fill Inlet message to turn off. A driving cycle  
consists of an engine start-up (after four or more hours with the engine  
off) followed by city/highway driving. Continuing to drive with the Check  
Fuel Fill Inlet lamp or Check Fuel Fill Inlet message on may cause the  
Service Engine Soon lamp to turn on as well.

WARNING: The fuel system may be under pressure. If you hear  
a hissing sound near the fuel filler door (Easy Fuel™ “no cap”  
fuel system), do not refuel until the sound stops. Otherwise, fuel may  
spray out, which could cause serious personal injury.  
Choosing the right fuel  
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum  
of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded  
fuel or any other fuel. The use of leaded fuel is prohibited by law and  
could damage your vehicle.  
Your vehicle was not designed to use fuel or fuel additives with metallic  
compounds, including manganese-based additives.  
Note: Use of any fuel other than those recommended may cause  
powertrain damage, a loss of vehicle performance, and repairs may not  
be covered under warranty.  
Octane recommendations  
Your vehicle is designed to use  
“Regular” unleaded gasoline with a  
pump (R+M)/2 octane rating of 87.  
87  
Some stations offer fuels posted as  
(R+M)/2 METHOD  
“Regular” with an octane rating  
below 87, particularly in high altitude areas. Fuels with octane levels  
below 87 are not recommended.  
Do not be concerned if your engine sometimes knocks lightly. However, if  
it knocks heavily under most driving conditions while you are using fuel  
with the recommended octane rating, see your authorized dealer to  
prevent any engine damage.

Maintenance and Specifications  
Fuel quality  
If you are experiencing starting, rough idle or hesitation driveability  
problems, try a different brand of unleaded gasoline. If the problems  
persist, see your authorized dealer.  
Do not add aftermarket fuel additive products to your fuel tank. It  
should not be necessary to add any aftermarket products to your fuel  
tank if you continue to use high quality fuel of the recommended octane  
rating. These products have not been approved for your engine and  
could cause damage to the fuel system. Repairs to correct the effects of  
using an aftermarket product in your fuel may not be covered by your  
warranty.  
Many of the world’s automakers approved the World-Wide Fuel Charter  
that recommends gasoline specifications to provide improved  
performance and emission control system protection for your vehicle.  
Gasolines that meet the World-Wide Fuel Charter should be used when  
available. Ask your fuel supplier about gasolines that meet the  
World-Wide Fuel Charter.  
Cleaner air  
Ford endorses the use of reformulated “cleaner-burning” gasolines to  
improve air quality, per the recommendations in the Choosing the right  
fuel section.  
Running out of fuel  
Avoid running out of fuel because this situation may have an adverse  
effect on powertrain components.  
If you have run out of fuel:  
You may need to cycle the ignition from off to on several times after  
refueling to allow the fuel system to pump the fuel from the tank to  
the engine. On restarting, cranking time will take a few seconds longer  
than normal.  
Normally, adding 1 gallon (3.8L) of fuel is enough to restart the  
engine. If the vehicle is out of fuel and on a steep grade, more than  
1 gallon (3.8L) may be required.  
The service engine soon  
indicator may come on. For more  
information on the service engine soon indicator, refer to Warning  
lights and chimes in the Instrument Cluster chapter.

Refilling with a portable fuel container  
With the Easy Fuel™ “no cap” fuel system, use the following directions  
when filling from a portable fuel container:  
WARNING: Do not insert the nozzle of portable fuel containers  
or aftermarket funnels into the Easy Fuel™ system. This could  
damage the fuel system and its seal, and may cause fuel to run onto  
the ground instead of filling the tank, which could result in serious  
personal injury.  
WARNING: Do not try to pry open or push open the Easy  
Fuel™ system with foreign objects. This could damage the fuel  
system and its seal and cause injury to you or others.  
When filling the vehicle’s fuel tank from a portable fuel container, use the  
included funnel.  
1. Locate the white plastic funnel. It  
is attached to the underside of the  
spare tire cover or is included with  
the tire changing tools.  
2. Slowly insert the funnel into the Easy Fuel™ system.  
3. Fill the vehicle with fuel from the portable fuel container.  
4. When done, clean the funnel or properly dispose of it. Extra funnels  
can be purchased from your authorized dealer if you choose to dispose  
of the funnel. Do not use aftermarket funnels; they will not work with  
the Easy Fuel™ system and can damage it. The included funnel has  
been specially designed to work safely with your vehicle.

ESSENTIALS OF GOOD FUEL ECONOMY  
Measuring techniques  
Your best source of information about actual fuel economy is you, the  
driver. You must gather information as accurately and consistently as  
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are  
NOT accurate as a measure of fuel economy. We do not recommend  
taking fuel economy measurements during the first 1,000 miles  
(1,600 km) of driving (engine break-in period). You will get a more  
accurate measurement after 2,000 miles–3,000 miles (3,000 km–5,000  
km).  
Filling the tank  
The advertised fuel capacity of the fuel tank on your vehicle is equal to  
the rated refill capacity of the fuel tank as listed in the Maintenance  
product specifications and capacities section of this chapter.  
The advertised capacity is the amount of the indicated capacity and the  
empty reserve combined. Indicated capacity is the difference in the  
amount of fuel in a full tank and a tank when the fuel gauge indicates  
empty. Empty reserve is the small amount of fuel remaining in the fuel  
tank after the fuel gauge indicates empty.  
The amount of usable fuel in the empty reserve varies and should  
not be relied upon to increase driving range. When refueling your  
vehicle after the fuel gauge indicates empty, you might not be  
able to refuel the full amount of the advertised capacity of the  
fuel tank due to the empty reserve still present in the tank.  
For consistent results when filling the fuel tank:  
Turn the engine/ignition switch to the off position prior to refueling,  
an error in the reading will result if the engine is left running.  
Use the same filling rate setting (low — medium — high) each time  
the tank is filled.  
Allow no more than two automatic click-offs when filling.  
Always use fuel with the recommended octane rating.  
Use a known quality gasoline, preferably a national brand.  
Use the same side of the same pump and have the vehicle facing the  
same direction each time you fill up.  
Have the vehicle loading and distribution the same every time.  
Your results will be most accurate if your filling method is consistent.

Calculating fuel economy  
1. Fill the fuel tank completely and record the initial odometer reading  
(in miles or kilometers).  
2. Each time you fill the tank, record the amount of fuel added (in  
gallons or liters).  
3. After at least three to five tank fill-ups, fill the fuel tank and record  
the current odometer reading.  
4. Subtract your initial odometer reading from the current odometer  
reading.  
5. Follow one of the simple calculations in order to determine fuel  
economy:  
Calculation 1: Divide total miles traveled by total gallons used.  
Calculation 2: Multiply liters used by 100, then divide by total  
kilometers traveled.  
Keep a record for at least one month and record the type of driving (city  
or highway). This will provide an accurate estimate of the vehicle’s fuel  
economy under current driving conditions. Additionally, keeping records  
during summer and winter will show how temperature impacts fuel  
economy. In general, lower temperatures give lower fuel economy.  
Driving style — good driving and fuel economy habits  
Give consideration to the lists that follow and you may be able to change  
a number of variables and improve your fuel economy.  
Habits  
Smooth, moderate operation can yield up to 10% savings in fuel.  
Steady speeds without stopping will usually give the best fuel  
economy.  
Idling for long periods of time (greater than one minute) may waste  
fuel.  
Anticipate stopping; slowing down may eliminate the need to stop.  
Sudden or hard accelerations may reduce fuel economy.  
Slow down gradually.  
Driving at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%  
less fuel than traveling at 65 mph [105 km/h]).  
Revving the engine before turning it off may reduce fuel economy.  
Using the air conditioner or defroster may reduce fuel economy.  
377  
2010 Explorer (exp)  
Owners Guide, 2nd Printing  
USA (fus)  
Maintenance and Specifications  
You may want to turn off the speed control in hilly terrain if  
unnecessary shifting between the top gears occurs. Unnecessary  
shifting of this type could result in reduced fuel economy.  
Warming up a vehicle on cold mornings is not required and may  
reduce fuel economy.  
Resting your foot on the brake pedal while driving may reduce fuel  
economy.  
Combine errands and minimize stop-and-go driving.  
Maintenance  
Keep tires properly inflated and use only recommended size.  
Operating a vehicle with the wheels out of alignment will reduce fuel  
economy.  
Use recommended engine oil. Refer to Maintenance product  
specifications and capacities in this chapter.  
Perform all regularly scheduled maintenance items. Follow the  
recommended maintenance schedule and owner maintenance checks  
found in scheduled maintenance information.  
Conditions  
Heavily loading a vehicle or towing a trailer may reduce fuel economy  
at any speed.  
Carrying unnecessary weight may reduce fuel economy (approximately  
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).  
Adding certain accessories to your vehicle (for example; bug  
deflectors, rollbars/light bars, running boards, ski/luggage racks) may  
reduce fuel economy.  
Fuel economy may decrease with lower temperatures during the first  
8–10 miles (12–16 km) of driving.  
Driving on flat terrain offers improved fuel economy as compared to  
driving on hilly terrain.  
Transmissions give their best fuel economy when operated in the top  
cruise gear and with steady pressure on the gas pedal.  
Four-wheel-drive operation (if equipped) is less fuel efficient than  
two-wheel-drive operation.  
Close windows for high speed driving.

EPA fuel economy estimates  
Every new vehicle should have a sticker on the window called the  
Monroney Label which contains EPA fuel economy estimates. Contact  
your authorized dealer if the Monroney Label is not supplied with your  
vehicle. The EPA fuel economy estimates should be your guide for the  
fuel economy comparisons with other vehicles. Your fuel economy may  
vary depending upon the method of operation and conditions.  
EMISSION CONTROL SYSTEM  
Your vehicle is equipped with various emission control components and a  
catalytic converter which will enable your vehicle to comply with  
applicable exhaust emission standards. To make sure that the catalytic  
converter and other emission control components continue to work  
properly:  
Use only the specified fuel listed.  
Avoid running out of fuel.  
Do not turn off the ignition while your vehicle is moving, especially at  
high speeds.  
Have the items listed in scheduled maintenance information  
performed according to the specified schedule.  
The scheduled maintenance items listed in scheduled maintenance  
information are essential to the life and performance of your vehicle  
and to its emissions system.  
If other than Ford, Motorcraftor Ford-authorized parts are used for  
maintenance replacements or for service of components affecting  
emission control, such non-Ford parts should be equivalent to genuine  
Ford Motor Company parts in performance and durability.  
WARNING: Do not park, idle, or drive your vehicle in dry grass  
or other dry ground cover. The emission system heats up the  
engine compartment and exhaust system, which can start a fire.  
Illumination of the service engine soon  
indicator, charging system  
warning light or the temperature warning light, fluid leaks, strange odors,  
smoke or loss of engine power could indicate that the emission control  
system is not working properly.  
An improperly operating or damaged exhaust system may allow exhaust  
to enter the vehicle. Have a damaged or improperly operating exhaust  
system inspected and repaired immediately.  
379  
2010 Explorer (exp)  
Owners Guide, 2nd Printing

Maintenance and Specifications  
WARNING: Exhaust leaks may result in entry of harmful and  
potentially lethal fumes into the passenger compartment.  
Do not make any unauthorized changes to your vehicle or engine. By  
law, vehicle owners and anyone who manufactures, repairs, services,  
sells, leases, trades vehicles, or supervises a fleet of vehicles are not  
permitted to intentionally remove an emission control device or prevent  
it from working. Information about your vehicle’s emission system is on  
the Vehicle Emission Control Information Decal located on or near the  
engine. This decal also lists engine displacement.  
Please consult your Warranty Guide/Customer Information Guide for  
complete emission warranty information.  
On board diagnostics (OBD-II)  
Your vehicle is equipped with a computer that monitors the engine’s  
emission control system. This system is commonly known as the On  
Board Diagnostics System (OBD-II). The OBD-II system protects the  
environment by ensuring that your vehicle continues to meet  
government emission standards. The OBD-II system also assists your  
authorized dealer in properly servicing your vehicle. When the service  
engine soon  
a malfunction. Temporary malfunctions may cause the service engine  
soon indicator to illuminate. Examples are:  
indicator illuminates, the OBD-II system has detected  
1. The vehicle has run out of fuel—the engine may misfire or run poorly.  
2. Poor fuel quality or water in the fuel—the engine may misfire or run  
poorly.  
3. The fuel fill inlet may not have been properly closed. See Easy Fuel™  
“no cap” fuel system in this chapter.  
4. Driving through deep water—the electrical system may be wet.  
These temporary malfunctions can be corrected by filling the fuel tank  
with good quality fuel, properly closing the fuel fill inlet or letting the  
electrical system dry out. After three driving cycles without these or any  
other temporary malfunctions present, the service engine soon  
indicator should stay off the next time the engine is started. A driving  
cycle consists of a cold engine startup followed by mixed city/highway  
driving. No additional vehicle service is required.  
380  
2010 Explorer (exp)  
Owners Guide, 2nd Printing  
USA (fus)  
Maintenance and Specifications  
If the service engine soon  
indicator remains on, have your vehicle  
serviced at the first available opportunity. Although some malfunctions  
detected by the OBD-II may not have symptoms that are apparent,  
continued driving with the service engine soon  
indicator on can  
result in increased emissions, lower fuel economy, reduced engine and  
transmission smoothness, and lead to more costly repairs.  
Readiness for Inspection/Maintenance (I/M) testing  
Some state/provincial and local governments may have  
Inspection/Maintenance (I/M) programs to inspect the emission control  
equipment on your vehicle. Failure to pass this inspection could prevent  
you from getting a vehicle registration. Your vehicle may not pass the I/M  
test if the service engine soon  
indicator is on or not working  
properly (bulb is burned out), or if the OBD-II system has determined  
that some of the emission control systems have not been properly  
checked. In this case, the vehicle is considered not ready for I/M testing.  
If the service engine soon  
indicator is on or the bulb does not  
work, the vehicle may need to be serviced. Refer to the On board  
diagnostics (OBD-II) description in this chapter.  
If the vehicle’s engine or transmission has just been serviced, or the  
battery has recently run down or been replaced, the OBD-II system may  
indicate that the vehicle is not ready for I/M testing. To determine if the  
vehicle is ready for I/M testing, turn the ignition key to the on position  
for 15 seconds without cranking the engine. If the service engine  
soon  
indicator blinks eight times, it means that the vehicle is not  
ready for I/M testing; if the service engine soon  
indicator stays on  
solid, it means that the vehicle is ready for I/M testing.  
The OBD-II system is designed to check the emission control system  
during normal driving. A complete check may take several days. If the  
vehicle is not ready for I/M testing, the following driving cycle consisting  
of mixed city and highway driving may be performed:  
15 minutes of steady driving on an expressway/highway followed by  
20 minutes of stop-and-go driving with at least four 30-second idle  
periods.  
Allow the vehicle to sit for at least eight hours without starting the  
engine. Then, start the engine and complete the above driving cycle. The  
engine must warm up to its normal operating temperature. Once started,  
do not turn off the engine until the above driving cycle is complete. If  
the vehicle is still not ready for I/M testing, the above driving cycle will  
have to be repeated.
