Note: The temporary tire size for your vehicle may be different from this example. Tire Quality Grades do not apply to this type of tire. 1. T: Indicates a type of tire, designated by the Tire and Rim Association (T&RA), that is intended for temporary service on cars, SUVs, minivans and light trucks. 2. 145: Indicates the nominal width of the tire in millimeters from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. 3. 80: Indicates the aspect ratio which gives the tire’s ratio of height to width. Numbers of 70 or lower indicate a short sidewall. 4. D: Indicates a “diagonal” type tire. R: Indicates a “radial” type tire. 5. 16: Indicates the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter. Location of the tire label You will find a Tire Label containing tire inflation pressure by tire size and other important information located on the B-Pillar or the edge of the driver’s door. Refer to the payload description and graphic in the Vehicle loading — with and without a trailer section. 252 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading TIRE PRESSURE MONITORING SYSTEM (TPMS) Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. 253 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading The Tire Pressure Monitoring System complies with part 15 of the FCC rules and with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. WARNING: The Tire Pressure Monitoring System is NOT a substitute for manually checking tire pressure. The tire pressure should be checked periodically (at least monthly) using a tire gauge, see Inflating your tires in this chapter. Failure to properly maintain your tire pressure could increase the risk of tire failure, loss of control, vehicle rollover and personal injury. Changing tires with TPMS Each road tire is equipped with a tire pressure sensor fastened to the inside rim of the wheel. The pressure sensor is covered by the tire and is not visible unless the tire is removed. The pressure sensor is located opposite (180 degrees) from the valve stem. Care must be taken when changing the tire to avoid damaging the sensor. It is recommended that you always have your tires serviced by an authorized dealer. The tire pressure should be checked periodically (at least monthly) using an accurate tire gauge, refer to Inflating your tires in this chapter. 254 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading Understanding your Tire Pressure Monitoring System (TPMS) The Tire Pressure Monitoring System measures pressure in your four road tires and sends the tire pressure readings to your vehicle. The Low Tire Pressure Warning Lamp will turn ON if the tire pressure is significantly low. Once the light is illuminated, your tires are under inflated and need to be inflated to the manufacturer’s recommended tire pressure. Even if the light turns ON and a short time later turns OFF, your tire pressure still needs to be checked. Visit www.checkmytires.org for additional information. When your temporary spare tire is installed When one of your road tires needs to be replaced with the temporary spare, the TPMS system will continue to identify an issue to remind you that the damaged road wheel/tire needs to be repaired and put back on your vehicle. To restore the full functionality of the Tire Pressure Monitoring System, have the damaged road wheel/tire repaired and remounted on your vehicle. For additional information, refer to Changing tires with TPMS in this section. 255 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading When you believe your system is not operating properly The main function of the Tire Pressure Monitoring System is to warn you when your tires need air. It can also warn you in the event the system is no longer capable of functioning as intended. Please refer to the following chart for information concerning your Tire Pressure Monitoring System: Possible cause Customer Action Required Low Tire Pressure Warning Light Solid Warning Light Tire(s) under-inflated 1. Check your tire pressure to ensure tires are properly inflated; refer to Inflating your tires in this chapter. 2. After inflating your tires to the manufacturer’s recommended inflation pressure as shown on the Tire Label (located on the edge of driver’s door or the B-Pillar), the vehicle must be driven for at least two minutes over 20 mph (32 km/h) before the light will turn OFF. Spare tire in use Your temporary spare tire is in use. Repair the damaged road wheel/tire and reinstall it on the vehicle to restore system functionality. For a description on how the system functions, refer to When your temporary spare tire is installed in this section. If your tires are properly inflated and your spare tire is not in use and the light remains ON, contact your authorized dealer as soon as possible. TPMS malfunction 256 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Low Tire Pressure Warning Light Flashing Warning Light Tires, Wheels and Loading Possible cause Customer Action Required Spare tire in use Your temporary spare tire is in use. Repair the damaged road wheel and re-mount it on the vehicle to restore system functionality. For a description of how the system functions under these conditions, refer to When your temporary spare tire is installed in this section. If your tires are properly inflated and your spare tire is not in use and the TPMS warning light still flashes, contact your authorized dealer as soon as possible. TPMS malfunction When inflating your tires When putting air into your tires (such as at a gas station or in your garage), the Tire Pressure Monitoring System may not respond immediately to the air added to your tires. It may take up to two minutes of driving over 20 mph (32 km/h) for the light to turn OFF after you have filled your tires to the recommended inflation pressure. How temperature affects your tire pressure The Tire Pressure Monitoring System (TPMS) monitors tire pressure in each pneumatic tire. While driving in a normal manner, a typical passenger tire inflation pressure may increase approximately 2 to 4 psi (14 to 28 kPa) from a cold start situation. If the vehicle is stationary over night with the outside temperature significantly lower than the daytime temperature, the tire pressure may decrease approximately 3 psi (21 kPa) for a drop of 30°F (17°C) in ambient temperature. This lower pressure value may be detected by the TPMS as being significantly lower than the recommended inflation pressure and activate the TPMS warning for low tire pressure. If the low tire pressure warning light is ON, visually check each tire to verify that no tire is flat. (If one or more tires are flat, repair as necessary.) Check air pressure in the road tires. If any tire is under-inflated, carefully drive the vehicle to the nearest location where air can be added to the tires. Inflate all the tires to the recommended inflation pressure. 257 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading SNOW TIRES AND CABLES WARNING: Snow tires must be the same size, load index, speed rating as those originally provided by Ford. The use of non-recommended tires and wheels could cause steering, suspension, axle or transfer case/power transfer unit failure. Using any tire or wheel not recommended by Ford may increase the risk of loss of vehicle control or vehicle rollover, which could result in personal injury or death. The tires on your vehicle have all-weather treads to provide traction in rain and snow. However, in some climates, using snow tires or traction devices may be necessary. Ford offers tire cables as a Ford approved accessory and recommends use of these or SAE class “S” tire cables. See your authorized dealer for more information on tire cables for your vehicle. Follow these guidelines when using snow tires and traction devices: • Use only SAE Class S cables. • Cables should only be used on the rear wheels. • Do not use tire cables or optional traction devices on 17, 18 or 20 inch • Install cables securely, verifying that the cables do not touch any • Drive cautiously. If you hear the cables rub or bang against the wiring, brake lines or fuel lines. wheels and tires. vehicle, stop and retighten them. If this does not work, remove the cables to prevent vehicle damage. • Avoid overloading your vehicle. • Remove the cables when they are no longer needed. • Do not use cables on dry roads. • Do not exceed 30 mph (48 km/h) with tire cables on your vehicle. Consult your authorized dealer for information on other Ford Motor Company approved methods of traction control. VEHICLE LOADING – WITH AND WITHOUT A TRAILER This section will guide you in the proper loading of your vehicle and/or trailer, to keep your loaded vehicle weight within its design rating capability, with or without a trailer. Properly loading your vehicle will provide maximum return of vehicle design performance. Before loading 258 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading your vehicle, familiarize yourself with the following terms for determining your vehicle’s weight ratings, with or without a trailer, from the vehicle’s Tire Label or Safety Compliance Certification Label: Base Curb Weight – is the weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers, cargo, or optional equipment. Vehicle Curb Weight – is the weight of your new vehicle when you picked it up from your authorized dealer plus any aftermarket equipment. Payload – is the combined weight of cargo and passengers that the vehicle is carrying. The maximum payload for your vehicle can be found on the Tire Label on the B-Pillar or the edge of the driver’s door (vehicles exported outside the US and Canada may not have a Tire Label). Look for “THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.” for maximum payload. The payload listed on the Tire Label is the maximum payload for the vehicle as built by the assembly plant. If any aftermarket or authorized-dealer installed equipment has been installed on the vehicle, the weight of the equipment must be subtracted from the payload listed on the Tire Label in order to determine the new payload. WARNING: The appropriate loading capacity of your vehicle can be limited either by volume capacity (how much space is available) or by payload capacity (how much weight the vehicle should carry). Once you have reached the maximum payload of your vehicle, do not add more cargo, even if there is space available. Overloading or improperly loading your vehicle can contribute to loss of vehicle control and vehicle rollover. 259 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading Example only: Cargo Weight – includes all weight added to the Base Curb Weight, including cargo and optional equipment. When towing, trailer tongue load or king pin weight is also part of cargo weight. GAW (Gross Axle Weight) – is the total weight placed on each axle (front and rear) – including vehicle curb weight and all payload. 260 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading GAWR (Gross Axle Weight Rating) – is the maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the Safety Compliance Certification Label located on the B-Pillar or the edge of the driver’s door. The total load on each axle must never exceed its GAWR. Note: For trailer towing information refer to Trailer towing found in this chapter or the RV and Trailer Towing Guide provided by your authorized dealer. GVW (Gross Vehicle Weight) – is the Vehicle Curb Weight + cargo + passengers. GVWR (Gross Vehicle Weight Rating) – is the maximum allowable weight of the fully loaded vehicle (including all options, equipment, passengers and cargo). The GVWR is shown on the Safety Compliance Certification Label located on the B-Pillar or the edge of the driver’s door. The GVW must never exceed the GVWR. 261 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading • Example only: WARNING: Exceeding the Safety Compliance Certification Label vehicle weight rating limits could result in substandard vehicle handling or performance, engine, transmission and/or structural damage, serious damage to the vehicle, loss of control and personal injury. 262 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading GCW (Gross Combined Weight) – is the weight of the loaded vehicle (GVW) plus the weight of the fully loaded trailer. GCWR (Gross Combined Weight Rating) – is the maximum allowable weight of the vehicle and the loaded trailer – including all cargo and passengers – that the vehicle can handle without risking damage. (Important: The towing vehicle’s braking system is rated for operation at GVWR, not at GCWR.) Separate functional brakes should be used for safe control of towed vehicles and for trailers where the GCW of the towing vehicle plus the trailer exceed the GVWR of the towing vehicle. The GCW must never exceed the GCWR. Maximum Loaded Trailer Weight – is the highest possible weight of a fully loaded trailer the vehicle can tow. It assumes a vehicle with only mandatory options, no cargo (internal or external), a tongue load of 10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel trailer), and driver only (150 lb. [68 kg]). Consult your authorized dealer (or the RV and Trailer Towing Guide provided by your authorized dealer) for more detailed information. Tongue Load or Fifth Wheel King Pin Weight – refers to the amount of the weight that a trailer pushes down on a trailer hitch. Examples: For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000 by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb. (227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875 lb. (782 to 1,304 kg) WARNING: Do not exceed the GVWR or the GAWR specified on the Safety Compliance Certification Label. WARNING: Do not use replacement tires with lower load carrying capacities than the original tires because they may lower the vehicle’s GVWR and GAWR limitations. Replacement tires with a higher limit than the original tires do not increase the GVWR and GAWR limitations. 263 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading WARNING: Exceeding any vehicle weight rating limitation could result in serious damage to the vehicle and/or personal injury. Steps for determining the correct load limit: 1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lb.” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lb. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1,400 lb. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lb. (1400-750 (5 x 150) = 650 lb.). In metric units (635-340 (5 x 68) = 295 kg.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. The following gives you a few examples on how to calculate the available amount of cargo and luggage load capacity: • Another example for your vehicle with 1,400 lb. (635 kg) of cargo and luggage capacity. You decide to go golfing. Is there enough load capacity to carry you, 4 of your friends and all the golf bags? You and four friends average 220 lb. (99 kg) each and the golf bags weigh approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 - (5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have enough load capacity in your vehicle to transport four friends and your golf bags. In metric units, the calculation would be: 635 kg - (5 x 99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg. • A final example for your vehicle with 1,400 lb. (635 kg) of cargo and luggage capacity. You and one of your friends decide to pick up cement from the local home improvement store to finish that patio you have been planning for the past 2 years. Measuring the inside of the vehicle with the rear seat folded down, you have room for 12-100 lb. (45 kg) bags of cement. Do you have enough load capacity 264 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading to transport the cement to your home? If you and your friend each weigh 220 lb. (99 kg), the calculation would be: 1400 - (2 x 220) - (12 x 100) = 1400 - 440 - 1200 = - 240 lb. No, you do not have enough cargo capacity to carry that much weight. In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 - 540 = -103 kg. You will need to reduce the load weight by at least 240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then the load calculation would be: 1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have the load capacity to transport the cement and your friend home. In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x 45 kg) = 635 - 198 - 405 = 32 kg. The above calculations also assume that the loads are positioned in your vehicle in a manner that does not overload the Front or the Rear Gross Axle Weight Rating specified for your vehicle on the Safety Compliance Certification Label found on the edge of the driver’s door. Special loading instructions for owners of pickup trucks and utility-type vehicles WARNING: For important information regarding safe operation of this type of vehicle, see the Preparing to drive your vehicle section in the Driving chapter of this Owner’s Guide. WARNING: Loaded vehicles may handle differently than unloaded vehicles. Extra precautions, such as slower speeds and increased stopping distance, should be taken when driving a heavily loaded vehicle. Your vehicle can haul more cargo and people than most passenger cars. Depending upon the type and placement of the load, hauling cargo and people may raise the center of gravity of the vehicle. Calculating the load your vehicle can carry/tow 1. Use the appropriate maximum GCWR chart (in the Trailer towing section in this chapter) for your type of engine and rear axle ratio. 2. Weigh your vehicle without cargo. To obtain correct weights, take your vehicle to a shipping company or an inspection station for trucks. 3. Subtract your loaded weight from the maximum GCWR in the chart. This is the maximum trailer weight your vehicle can tow. It must be below the maximum trailer weight shown in the chart. 265 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading TRAILER TOWING Trailer towing with your vehicle may require the use of a trailer tow option package. Trailer towing puts additional loads on your vehicle’s engine, transmission, axle, brakes, tires, and suspension. For your safety and to maximize vehicle performance, be sure to use the proper equipment while towing. Follow these guidelines to ensure safe towing procedure: • Do not tow a trailer until your vehicle has been driven at least • Stay within your vehicle’s load limits. • Thoroughly prepare your vehicle for towing. Refer to Preparing to • Use extra caution when driving while trailer towing. Refer to Driving • Service your vehicle more frequently if you tow a trailer. Refer to the severe duty schedule in the scheduled maintenance information. • Refer to the instructions included with towing accessories for the while you tow in this chapter. 1,000 miles (1600 km). tow in this chapter. proper installation and adjustment specifications. Do not exceed the maximum loads listed on the Safety Compliance Certification label. For load specification terms found on the label, refer to Vehicle loading in this chapter when figuring the total weight of your vehicle. Your vehicle is equipped with a standard Class II integrated hitch and requires only a draw bar and ball with a 19 mm (3/4 inch) shank diameter. An optional Class III/Class IV hitch is also available. Note: Do not exceed the GVWR or the GAWR specified on the certification label. WARNING: Towing trailers beyond the maximum recommended gross trailer weight exceeds the limit of the vehicle and could result in engine damage, transmission damage, structural damage, loss of vehicle control, vehicle rollover and personal injury. 266 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading 4x2 GCWR (Gross Combined Weight Rating)/Trailer Weight Engine Rear axle ratio Maximum GCWR-lb.

Contact your authorized dealer or a reliable trailer dealer as soon as possible if you require assistance. Hitches Do not use hitches that clamp onto the vehicle bumper. Use a load carrying hitch. You must distribute the load in your trailer so that 10–15% of the total weight of the trailer is on the tongue, not to exceed the maximum tongue loads as stated: • Class II receiver: 350 lb. (159 kg) • Class III/IV receiver: 500 lb. (227 kg) (weight carrying); 740 lb. (336 kg) (weight distributing) Safety chains Always connect the trailer’s safety chains to the frame or hook retainers of the vehicle hitch. To connect the trailer’s safety chains, cross the chains under the trailer tongue and allow slack for turning corners. If you use a rental trailer, follow the instructions that the rental agency gives to you. 268 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading Class III Trailer Hitch Safety Chain Loops can be used as recovery hooks. Do not attach safety chains to the bumper. Trailer brakes Electric brakes and manual, automatic or surge-type trailer brakes are safe if installed properly and adjusted to the manufacturer’s specifications. The trailer brakes must meet local and Federal regulations. WARNING: Do not connect a trailer’s hydraulic brake system directly to your vehicle’s brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase. The braking system of the tow vehicle is rated for operation at the GVWR not GCWR. Trailer lamps Trailer lamps are required on most towed vehicles. Make sure all running lights, brake lights, turn signals and hazard lights are working. Contact your authorized dealer or trailer rental agency for proper instructions and equipment for hooking up trailer lamps. WARNING: Never connect any trailer lighting to the vehicle’s taillamp circuits, because it may damage the electrical system resulting in fire. Contact your authorized dealer as soon as possible for assistance in proper trailer tow wiring installation. Additional electrical equipment may be required. 269 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading Driving while you tow When towing a trailer: • To ensure proper “break-in” of powertrain components, do not trailer • To ensure proper “break-in” of powertrain components during the first tow during the first 1,000 miles (1,600 km) of a new vehicle. 500 miles (800 km) of trailer towing, drive no faster than 70 mph (113 km/h) with no full throttle starts. • Turn off the speed control. The speed control may shut off automatically when you are towing on long, steep grades. • Consult your local motor vehicle speed regulations for towing a trailer. • To eliminate excessive shifting, use a lower gear. This will also assist in transmission cooling. For additional information, refer to Automatic transmission operation in the Driving chapter. • Under extreme conditions with large frontal trailers, high outside temperatures and highway speeds, the coolant gauge may indicate higher than normal coolant temperatures. If this occurs, reduce speed until the coolant temperature returns to the normal range. Refer to Engine coolant temperature gauge in the Instrument Cluster chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. Servicing after towing If you tow a trailer for long distances, your vehicle will require more frequent service intervals. Refer to your scheduled maintenance information for more information. Trailer towing tips • Practice turning, stopping and backing up before starting on a trip to get the feel of the vehicle trailer combination. When turning, make wider turns so the trailer wheels will clear curbs and other obstacles. • Allow more distance for stopping with a trailer attached. • If you are driving down a long or steep hill, shift to a lower gear. Do not apply the brakes continuously, as they may overheat and become less effective. • The trailer tongue weight should be 10–15% of the loaded trailer weight. 270 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading • If you will be towing a trailer frequently in hot weather, hilly conditions, at GCWR, or any combination of these factors, consider refilling your rear axle with synthetic gear lube if not already so equipped. Refer to the Maintenance and Specifications chapter for the lubricant specification. Remember that regardless of the rear axle lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a new vehicle, and that the first 500 miles (800 km) of towing be done at no faster than 70 mph (113 km/h) with no full throttle starts. • After you have traveled 50 miles (80 km), thoroughly check your • To aid in engine/transmission cooling and A/C efficiency during hot • Vehicles with trailers should not be parked on a grade.

Launching or retrieving a boat Disconnect the wiring to the trailer before backing the trailer into the water. Reconnect the wiring to the trailer after the trailer is removed from the water. When backing down a ramp during boat launching or retrieval: • do not allow the static water level to rise above the bottom edge of • do not allow waves to break higher than 6 inches (15 cm) above the the rear bumper. bottom edge of the rear bumper. Exceeding these limits may allow water to enter vehicle components: • causing internal damage to the components. • affecting driveability, emissions and reliability. Replace the rear axle lubricant any time the axle has been submerged in water. Rear axle lubricant quantities are not to be checked or changed unless a leak is suspected or repair required. RECREATIONAL TOWING Follow these guidelines if you have a need for recreational (RV) towing. An example of recreational towing would be towing your vehicle behind a motorhome. These guidelines are designed to ensure that your transmission is not damaged. Note: Put your climate control system in recirculated air mode to prevent exhaust fumes from entering the vehicle. Refer to the Climate controls chapter for more information. 271 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Tires, Wheels and Loading 2WD vehicles: Do not tow your vehicle with any wheels on the ground, as vehicle or transmission damage may occur. It is recommended to tow your vehicle with all four (4) wheels off the ground such as when using a car-hauling trailer. Otherwise, no recreational towing is permitted. In case of a roadside emergency with a disabled vehicle, see Wrecker towing in the Roadside Emergencies chapter. 4WD vehicles with electronic shift transfer case (Neutral tow kit accessory): An accessory is available that allows you to tow your vehicle, behind another vehicle, with all the wheels on the ground. Contact your authorized dealer for more details. Do not tow your vehicle with all wheels on the ground unless you install the neutral tow kit as vehicle damage may occur. In case of a roadside emergency with a disabled vehicle, see Wrecker towing in the Roadside Emergencies chapter. AWD vehicles: Do not tow your vehicle with any wheels on the ground, as vehicle or transmission damage may occur. It is recommended to tow your vehicle with all four (4) wheels off the ground such as when using a car-hauling trailer. Otherwise, no recreational towing is permitted.

Off— locks the gearshift lever and allows key removal. This position also shuts the engine and all electrical accessories off. 2. Accessory— allows the electrical accessories such as the radio to operate while the engine is not running. 3. On— all electrical circuits operational. Warning lights illuminated. Key position when driving. 4. Start— cranks the engine. Release the key as soon as the engine starts. Preparing to start your vehicle Engine starting is controlled by the powertrain control system. This system meets all Canadian interference-causing equipment standard requirements regulating the impulse electrical field strength of radio noise. When starting a fuel-injected engine, don’t press the accelerator before or during starting. Only use the accelerator when you have difficulty starting the engine. For more information on starting the vehicle, refer to Starting the engine in this chapter. WARNING: Extended idling at high engine speeds can produce very high temperatures in the engine and exhaust system, creating the risk of fire or other damage. WARNING: Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. WARNING: Do not start your vehicle in a closed garage or in other enclosed areas. Exhaust fumes can be toxic. Always open the garage door before you start the engine. See Guarding against exhaust fumes in this chapter for more instructions. 273 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving WARNING: If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important safety precautions When the engine starts, the idle RPM runs faster to warm the engine. If the engine idle speed does not slow down automatically, have the vehicle checked. If the vehicle is operated in a heavy snow storm or blowing snow conditions, the engine air induction may become partially clogged with snow and/or ice. If this occurs the engine may experience a significant reduction in power output. At the earliest opportunity, clear all snow and/or ice away for the air induction inlet. Before starting the vehicle: 1. Make sure all occupants buckle their safety belts. For more information on safety belts and their proper usage, refer to the Seating and Safety Restraints chapter. 2. Make sure the headlamps and electrical accessories are off. • Make sure the parking brake is set. 274 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) • Make sure the gearshift is in P (Park). Driving O/D 3. Turn the key to 3 (on) without turning the key to 4 (start). Some warning lights will briefly illuminate. See Warning lights and chimes in the Instrument Cluster chapter for more information regarding the warning lights. 275 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving Starting the engine 1. Turn the key to 3 (on) without turning the key to 4 (start). If there is difficulty in turning the key, rotate the steering wheel until the key turns freely. This condition may occur when: • the front wheels are turned • a front wheel is against the curb 2. Turn the key to 4 (start), then release the key as soon as the engine begins cranking. Your vehicle has a computer assisted cranking system that assists in starting the engine. After releasing the key from the 4 (start) position, the engine may continue cranking for up to 10 seconds or until the vehicle starts. Note: Cranking may be stopped at any time by turning the key to the off position. 3. After idling for a few seconds, release the parking brake, apply the brake, shift into gear and drive. Note: If the engine does not start on the first try, turn the key to the off position, wait 10 seconds and try Step 2 again. If the engine still fails to start, press the accelerator to the floor and try Step 2 again, keeping the accelerator on the floor until the engine begins to accelerate above cranking speeds; this will allow the engine to crank with the fuel shut off in case the engine is flooded with fuel. Guarding against exhaust fumes Carbon monoxide is present in exhaust fumes. Take precautions to avoid its dangerous effects. WARNING: If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important ventilating information If the engine is idling while the vehicle is stopped for a long period of time, open the windows at least 1 inch (2.5 cm) or adjust the heating or air conditioning to bring in fresh air. 276 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving ENGINE BLOCK HEATER (IF EQUIPPED) An engine block heater warms the engine coolant which aids in starting and allows the heater/defroster system to respond quickly. If your vehicle is equipped with this system, your equipment includes a heater element which is installed in your engine block and a wire harness which allows the user to connect the system to a grounded 120 volt A/C electrical source. The block heater system is most effective when outdoor temperatures reach below 0°F (-18°C). WARNING: Failure to follow engine block heater instructions could result in property damage or physical injury. WARNING: To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. Prior to using the engine block heater, follow these recommendations for proper and safe operation: • For your safety, use an outdoor extension cord that is product certified by Underwriter’s Laboratory (UL) or Canadian Standards Association (CSA). Use only an extension cord that can be used outdoors, in cold temperatures, and is clearly marked “Suitable for Use with Outdoor Appliances.” Never use an indoor extension cord outdoors; it could result in an electric shock or fire hazard. • Use a 16 gauge outdoor extension cord, minimum. • Use as short an extension cord as possible. • Do not use multiple extension cords. Instead, use one extension cord which is long enough to reach from the engine block heater cord to the outlet without stretching. • Make certain that the extension cord is in excellent condition (not patched or spliced). Store your extension cord indoors at temperatures above 32°F (0°C). Outdoor conditions can deteriorate extension cords over a period of time. • To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two pronged (cheater) adapters. Also ensure that the block heater, especially the cord, is in good condition before use. • Make sure that when in operation, the extension cord plug/engine block heater cord plug connection is free and clear of water in order to prevent possible shock or fire. 277 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving • Be sure that areas where the vehicle is parked are clean and clear of all combustibles such as petroleum products, dust, rags, paper and similar items. • Be sure that the engine block heater, heater cord and extension cord are solidly connected. A poor connection can cause the cord to become very hot and may result in an electrical shock or fire. Be sure to check for heat anywhere in the electrical hookup once the system has been operating for approximately a half hour. • Finally, have the engine block heater system checked during your fall tune-up to be sure it’s in good working order. How to use the engine block heater Ensure the receptacle terminals are clean and dry prior to use. To clean them, use a dry cloth. Depending on the type of factory installed equipment, your engine block heater will use .4 to 1.0 kilowatt-hours of energy per hour of use. Your factory installed block heater system does not have a thermostat; however, maximum temperature is attained after approximately three hours of operation. Block heater operation longer than three hours will not improve system performance and will unnecessarily use additional electricity. Make sure system is unplugged and properly stowed before driving the vehicle. While not in use, make sure the protective cover seals the prongs of the engine block heater cord plug. BRAKES Occasional brake noise is normal. If a metal-to-metal, continuous grinding or continuous squeal sound is present, the brake linings may be worn-out and should be inspected by an authorized dealer. If the vehicle has continuous vibration or shudder in the steering wheel while braking, the vehicle should be inspected by an authorized dealer. Refer to Warning lights and chimes in the Instrument Cluster chapter for information on the brake system warning light. BRAKE Four-wheel anti-lock brake system (ABS) Your vehicle is equipped with an anti-lock braking system (ABS). This system helps you maintain steering control during emergency stops by keeping the brakes from locking. Noise from the ABS pump motor and 278 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving brake pedal pulsation may be observed during ABS braking and the brake pedal may suddenly travel a little farther as soon as ABS braking is done and normal brake operation resumes. These are normal characteristics of the ABS and should be no reason for concern. Using ABS When hard braking is required, apply continuous force on the brake pedal; do not pump the brake pedal since this will reduce the effectiveness of the ABS and will increase your vehicle’s stopping distance. The ABS will be activated immediately, allowing you to retain steering control during hard braking and on slippery surfaces. However, the ABS does not decrease stopping distance. ABS warning lamp The ABS lamp in the instrument cluster momentarily illuminates when the ignition is turned on. If the light does not illuminate during start up, remains on or flashes, the ABS may be disabled and may need to be serviced. Even when the ABS is disabled, normal braking is still effective. If your BRAKE warning lamp illuminates with the parking brake released, have your brake system serviced immediately. BRAKE ABS Parking brake Apply the parking brake whenever the vehicle is parked. To set the parking brake, press the parking brake pedal down until the pedal stops. 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) 279 Driving The BRAKE warning lamp in the instrument cluster illuminates and remains illuminated (when the ignition is turned on) until the parking brake is released. BRAKE WARNING: Always set the parking brake fully and make sure that the gearshift is securely latched in P (Park). WARNING: If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. The parking brake is not recommended to stop a moving vehicle. However, if the normal brakes fail, the parking brake can be used to stop your vehicle in an emergency. Since the parking brake applies only the rear brakes, the vehicle’s stopping distance will increase greatly and the handling of your vehicle will be adversely affected. Pull the release lever to release the brake. Driving with the parking brake on will cause the brakes to wear out quickly and reduce fuel economy. 280 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving ADVANCETRAC姞 WITH ROLL STABILITY CONTROL™ (RSC姞) STABILITY ENHANCEMENT SYSTEM WARNING: Vehicle modifications involving braking system, aftermarket roof racks, suspension, steering system, tire construction and/or wheel/tire size may change the handling characteristics of the vehicle and may adversely affect the performance of the AdvanceTrac威 with RSC威 system. In addition, installing any stereo loudspeakers may interfere with and adversely affect the AdvanceTrac威 with RSC威 system. Install any aftermarket stereo loudspeaker as far as possible from the front center console, the tunnel, and the front seats in order to minimize the risk of interfering with the AdvanceTrac威 with RSC威 sensors. Reducing the effectiveness of the AdvanceTrac威 with RSC威 system could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. WARNING: Remember that even advanced technology cannot defy the laws of physics. It’s always possible to lose control of a vehicle due to inappropriate driver input for the conditions. Aggressive driving on any road condition can cause you to lose control of your vehicle increasing the risk of personal injury or property damage. Activation of the AdvanceTrac威 with RSC威 system is an indication that at least some of the tires have exceeded their ability to grip the road; this could reduce the operator’s ability to control the vehicle, potentially resulting in a loss of vehicle control, vehicle rollover, personal injury and death. If your AdvanceTrac威 with RSC威 system activates, SLOW DOWN. WARNING: If a failure has been detected within the AdvanceTrac威 with RSC威 system, the “sliding car” icon will illuminate steadily. Verify that the AdvanceTrac威 with RSC威 system is not manually disabled (push the AdvanceTrac威 with RSC威 button located on the center of the instrument panel). If the “sliding car” icon authorized dealer immediately. Operating your vehicle with AdvanceTrac威 with RSC威 disabled could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. still illuminates steadily, have the system serviced by an 281 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving The AdvanceTrac威 with RSC威 system provides the following stability enhancement features for certain driving situations: • Traction Control System (TCS), which functions to help avoid • Electronic Stability Control (ESC), which functions to help avoid skids • Roll Stability Control™ (RSC威), which functions to help avoid a drive-wheel spin and loss of traction. or lateral slides vehicle roll-over. in The AdvanceTrac威 with RSC威 system automatically enables each time the engine is started. All features of the AdvanceTrac威 with RSC威 system (TCS, ESC, and RSC威) are active and monitor the vehicle from start-up. However, the system will only intervene if the driving situation requires it. The AdvanceTrac威 with RSC威 system includes an AdvanceTrac威 with RSC威 button on the center of the instrument panel, and a “sliding in the instrument car” icon cluster. The “sliding car” icon the instrument cluster will illuminate temporarily during start-up as part of a normal system self-check, or during driving if a driving situation causes the AdvanceTrac威 with RSC威 system to operate. If the “sliding illuminates steadily, verify that the AdvanceTrac威 with car” icon RSC威 system is not manually disabled by pressing the AdvanceTrac威 with RSC威 button located on the center stack of the instrument panel. If the “sliding car” icon center (if equipped) displays SERVICE RSC NOW, have the system serviced by an authorized dealer immediately. When AdvanceTrac威 with RSC威 performs a normal system self-check, some drivers may notice a slight movement of the brake, and/or a rumble, grunting, or grinding noise after startup and when driving off. When an event occurs that activates AdvanceTrac威 with RSC威 you may experience the following: • A slight deceleration of the vehicle • The “sliding car” • A vibration in the pedal when your foot is on the brake pedal • If the driving condition is severe and your foot is not on the brake, the brake pedal may move as the systems applies higher brake forces. You may also hear a whoosh of air from under the instrument panel during this severe condition. remains steadily illuminated, or if the message indicator light will flash. 282 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving in the instrument cluster • The brake pedal may feel stiffer than usual. Traction Control System (TCS) The TCS is a driver aid feature that helps your vehicle maintain traction of the wheels, typically when driving on slippery and/or hilly road surfaces, by detecting and controlling wheel spin. Excessive wheel spin is controlled in two ways, which may work separately or in tandem: engine traction control and brake traction control. Engine traction control works to limit drive-wheel spin by momentarily reducing engine power. Brake traction control works to limit wheel spin by momentarily applying the brakes to the wheel that is slipping. Traction control is most active at low speeds. During TCS events the “sliding car” icon will flash. If the TCS is activated excessively in a short period of time, the braking portion of the system may become temporarily disabled to allow the brakes to cool down. In this situation, TCS will use only engine power reduction or transfer to help control the wheels from over-spinning. When the brakes have cooled down, the system will regain all features. Anti-lock braking, RSC威, and ESC are not affected by this condition and will continue to function during the cool-down period. The engine traction control and brake traction control systems may be deactivated in certain situations. See the Switching Off AdvanceTrac威 with RSC威 section following. Electronic Stability Control (ESC) Electronic stability control (ESC) may enhance your vehicle’s directional stability during adverse maneuvers, for example when cornering severely or avoiding objects in the roadway. The ESC operates by applying brakes to one or more of the wheels individually and, if necessary, reducing engine power if the system detects that the vehicle is about to skid or slide laterally. During ESC events the “sliding car” icon will flash. Certain adverse driving maneuvers may activate the ESC system, which include but are not limited to: • Taking a turn too fast • Maneuvering quickly to avoid an accident, pedestrian or obstacle • Driving over a patch of ice or other slippery surfaces in the instrument cluster 283 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving • Changing lanes on a snow-rutted road • Entering a snow-free road from a snow-covered side street, or vice • Entering a paved road from a gravel road, or vice versa • Cornering while towing a heavily loaded trailer (refer to Trailer versa towing in the Tires, Wheels and Loading chapter). in the instrument cluster will flash. The ESC system may be deactivated in certain situations. See the Switching Off AdvanceTrac威 with RSC威 section following. Roll Stability Control™ (RSC威) Roll Stability Control™ (RSC威) may help to maintain roll stability of the vehicle during adverse maneuvers. The RSC威 system operates by detecting the vehicle’s roll motion and the rate at which it changes and by applying the brakes to one or more wheels individually. During an event that activates the RSC威 system, the “sliding car” icon Certain adverse driving maneuvers may activate the RSC威 system, which include: • Emergency lane-change • Taking a turn too fast • Quick maneuvering to avoid an accident, pedestrian or obstacle The RSC威 system may be deactivated in certain situations. See the Switching Off AdvanceTrac威 with RSC威 section following. Switching Off AdvanceTrac威 with RSC威 If the vehicle is stuck in snow, mud or sand, and seems to lose engine power, switching off certain features of the AdvanceTrac威 with RSC威 system may be beneficial because the wheels are allowed to spin. This will restore full engine power and will enhance momentum through the obstacle. To switch off the AdvanceTrac威 with RSC威 system press the AdvanceTrac威 with RSC威 button. Full features of the AdvanceTrac威 with RSC威 system can be restored by pressing the AdvanceTrac威 with RSC威 button again or by turning off and restarting the engine. If you switch off the AdvanceTrac威 with RSC威 system, the “sliding car” will illuminate steadily. Pressing the AdvanceTrac威 with RSC威 icon button again will turn off the “sliding car” icon In R (Reverse), ABS and the engine traction control and brake traction control features will continue to function; however, ESC and RSC威 are disabled. 284 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) AdvanceTrac威 with RSC威 Features “Sliding car” icon RSC威 ESC Engine traction control Driving Brake traction control Off Enabled Enabled Enabled Enabled Illuminated solid Disabled below 25 mph (40 km/h) Disabled below 25 mph (40 km/h) Disabled below 25 mph (40 km/h) Enabled Button functions Default at start-up Button pressed momentarily then solid Flashes Disabled Disabled Disabled Disabled illuminated below 25 mph (40 km/h) below 25 mph (40 km/h) Button pressed and held more than five seconds Trailer Sway Control When properly equipped, trailer sway control will use the vehicle’s AdvanceTrac威 with RSC威 system to detect and help reduce trailer sway by applying brake force at individual wheels and, if necessary, by reducing engine power. Trailer sway control is only enabled above 40 mph (64 km/h). below 25 mph below 25 mph (40 km/h) (40 km/h) WARNING: Trailer sway control does not prevent a trailer from swaying, it mitigates the sway from increasing once it has occurred. If you are experiencing trailer sway it is likely that the trailer is improperly loaded for the correct tongue weight or the speed of the vehicle and trailer is too high. Pull the vehicle-trailer over to a safe location to check the trailer weight distribution and tongue load and reduce speed to a safe level while towing. If trailer sway is experienced, SLOW DOWN. icon in the instrument cluster During trailer sway control events, the will flash momentarily. The message center will also display TRAILER SWAY REDUCE SPEED. In some cases when trailer sway is detected, the vehicle speed is too high and may be at or above a speed at which trailer sway will grow continuously. This may cause the system to activate multiple times, and you may experience a slight deceleration of the vehicle. 285 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving Disabling Trailer Sway Control Trailer sway control can be disabled during any key cycle. Refer to Message center in the Instrument Cluster chapter for more information. Note that even if it was disabled before turning off the vehicle, Trailer Sway Control will be re-enabled at each new key cycle. WARNING: Turning off trailer sway control increases the risk of loss of vehicle control, serious injury, or death. Ford does not recommend disabling this feature except in situations where speed reduction may be detrimental (e.g., hill climbing), the driver has significant trailer towing experience, and can control trailer sway and maintain safe operation. (below the MIN mark on the reservoir). stops) for more than a few seconds when the engine is running STEERING To help prevent damage to the power steering system: • Never hold the steering wheel at its furthest turning points (until it • Do not operate the vehicle with a low power steering pump fluid level • Some noise is normal during operation. If the noise is excessive, check for low power steering pump fluid level before seeking service by your authorized dealer. • Heavy or uneven steering efforts may be caused by low power steering pump fluid level. Check for low power steering pump fluid level before seeking service by your authorized dealer. • Do not fill the power steering pump reservoir above the MAX mark on the reservoir, as this may result in leaks from the reservoir. If the power steering system breaks down (or if the engine is turned off), you can steer the vehicle manually, but it takes more effort. If the steering wanders or pulls, check for: • an improperly inflated tire • uneven tire wear • loose or worn suspension components • loose or worn steering components • improper steering alignment A high crown in the road or high crosswinds may also make the steering seem to wander/pull. 286 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving PREPARING TO DRIVE WARNING: Utility vehicles have a significantly higher rollover rate than other types of vehicles. WARNING: In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seat belt. Utility vehicles and trucks have larger tires and increased ground clearance, giving the vehicle a higher center of gravity than a passenger car. WARNING: Vehicles with a higher center of gravity such as utility vehicles and trucks handle differently than vehicles with a lower center of gravity. Utility vehicles and trucks are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns, excessive speed or abrupt maneuvers in these vehicles. Failure to drive cautiously could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. WARNING: Loaded vehicles, with a higher center of gravity, may handle differently than unloaded vehicles. Do not overload your vehicle and use extra precautions, such as driving at slower speeds, avoiding abrupt steering changes and allowing for increased stopping distance, when driving a heavily loaded vehicle. Over-loading or loading the vehicle improperly can deteriorate handling capability and contribute to loss of vehicle control and vehicle rollover. BRAKE-SHIFT INTERLOCK This vehicle is equipped with a brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) when the ignition is in the on position unless brake pedal is pressed. If you cannot move the gearshift lever out of P (Park) with ignition in the on position and the brake pedal pressed: 1. Apply the parking brake, turn ignition key to off, then remove the key. 287 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving 2.

Using a screwdriver (or equivalent), remove the access panel and depress the shifter lever on the shift mechanism. 4. Apply the brake and shift into N (Neutral). 5. Return the cover plug to the console access hole. Start the vehicle. If it is necessary to use the above procedure to move the gearshift lever, it is possible that a fuse has blown or the vehicle’s brakelamps are not operating properly. Refer to Fuses and relays in the Roadside Emergencies chapter. WARNING: Do not drive your vehicle until you verify that the brakelamps are working. WARNING: Always set the parking brake fully and make sure the gearshift is latched in P (Park). Turn the ignition to the off position and remove the key whenever you leave your vehicle. WARNING: If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. AUTOMATIC TRANSMISSION OPERATION Driving with a 5–speed automatic transmission (if equipped) This vehicle is equipped with an adaptive transmission control strategy. This adaptive transmission control strategy offers the optimal transmission operation and shift quality. When the vehicle’s battery has been disconnected for any type of service or repair, the transmission will need to relearn the normal shift strategy parameters, much like having to reset your radio stations when your vehicle battery has been disconnected. The adaptive transmission control strategy allows the transmission to relearn these operating parameters. This learning process could take several transmission upshifts and downshifts; during this 288 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving learning process, slightly firmer shifts may occur. After this learning process, normal shift feel and shift scheduling will resume. P (Park) This position locks the transmission and prevents the rear wheels from turning. To put your vehicle in gear: • Start the engine • Press the brake pedal • Press the gearshift release button on the front of the lever and move the gearshift lever into the desired gear To put your vehicle in P (Park): • Come to a complete stop • Move the gearshift lever and securely latch it in P (Park) WARNING: Always set the parking brake fully and make sure the gearshift is latched in P (Park).

WARNING: To help avoid personal injury, please read and understand the limitations of the reverse sensing system as contained in this section. The park assist is only an aid for some (generally large and fixed) objects when moving in reverse on a flat surface at “parking speeds”. Inclement weather may also affect the function of the RSS; this may include reduced performance or a false activation. WARNING: To help avoid personal injury, always use caution when in R (Reverse) and when using the reverse sensing system. WARNING: This system is not designed to prevent contact with small or moving objects. The system is designed to provide a warning to assist the driver in detecting objects to avoid damaging the vehicle. The system may not detect smaller objects, particularly those close to the ground. WARNING: Certain add-on devices such as large trailer hitches, bike or surfboard racks and any device that may block the normal detection zone of the reverse sensing system may create false beeps. The system will assist the driver in detecting certain objects while the vehicle moves in reverse at speeds less than 6 mph (10 km/h). The system is not effective at speeds greater than 6 mph (10 km/h) and may not detect certain angular or moving objects. 294 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving The system detects obstacles within approximately 16 feet (five meters), at speeds above 2.5 mph (4 km/h) behind the rear bumper with a decreased coverage area at the outer corners of the bumper. If vehicle speed is below 2.5 mph (4 km/h), the system detects obstacles within approximately 9 feet (2.6 meters) behind the rear bumper with a decreased coverage area at the outer corners of the bumper. As you move closer to the obstacle, the rate of the tone increases. When the distance to the obstacle is approximately less than 18 inches (45.0 cm), the tone will sound continuously. If the system detects an object that is approaching the vehicle at such a rate that rapid braking is required, a very high rate tone will sound. If this tone is heard while reversing, the driver is advised to slow down immediately until the tone either changes to a slower rate or stops. While receiving a warning the radio volume will be reduced to a predetermined level. After the warning goes away, the radio will return to the previous value. Audible Warnings Distance to Object Warning Speed above 2.5 mph (4 km/h) up to 1.6 feet (.5 meters) 1.6 feet (.5 meters) to 3.1 feet (1 meter) 3.1 feet (1 meter) to 5.7 feet (1.8 meters) 5.7 feet (1.8 meters) to 9 feet (2.8 meters) 9 feet (2.8 meters) to 13 feet (4 meters) Solid Fast beep Medium/fast beep Medium beep Medium/slow beep 295 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving Audible Warnings Distance to Object 13 feet (4 meters) to 19.6 feet (6 meters) Slow beep Warning Speed below 2.5 mph (4 km/h) No sound Slow beep Medium beep Medium/slow beep Solid Fast beep up to 1.4 feet (.4 meters) 1.4 feet (.4 meters) to 3 feet (.9 meters) 3 feet (.9 meters) to 4.5 feet (1.4 meters) 4.5 feet (1.4 meters) to 6.3 feet (1.9 meters) 6.3 feet (1.9 meters) to 8.7 feet (2.6 meters) 8.7 feet (2.6 meters) to 16.4 feet (5 meters) The reverse sensing system is automatically enabled when the gearshift lever is placed in R (Reverse) and the ignition is on. A control in the message center allows the driver to disable the system, refer to Message center in the Instrument Cluster chapter for more information. The message center will indicate the system is off and will not allow the driver to switch the system on to indicate a failure of the reverse sensing system. The radar sensor is located behind the rear bumper/fascia. Always keep the rear bumper/fascia free from snow, ice and large accumulations of dirt. These elements may cause the system to operate inaccurately. If the vehicle sustains damage to the rear bumper/fascia, leaving it misaligned or bent, the sensing zone may be altered causing inaccurate measurement of obstacles or false alarms. FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED) WARNING: For important information regarding safe operation of this type of vehicle, see Preparing to drive your vehicle in this chapter. 296 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving Four–wheel drive (4WD) supplies power to all four wheels. Do not use 4X4 High or 4X4 Low on dry, hard surfaced roads. Doing so will produce excessive noise, increase tire wear and may damage drive components. 4X4 High and 4X4 Low are only intended for consistently slippery or loose surfaces. The use of 4X4 High or 4X4 Low on these surfaces may produce some noise, such as occasional clunks, but will not damage the drive system. If equipped with the Electronic Shift 4WD System, and 4WD Low is selected while the vehicle is moving above 3 mph (5 km/h), the 4WD system will not engage. This is normal and should be no reason for concern. Refer to Shifting to/from 4WD Low for proper operation. System indicator lights • 4X4 - momentarily illuminates when the vehicle is started. Illuminates when 4X4 HIGH (4WD High) is selected. • 4X4 LOW – momentarily illuminates when the vehicle is started. Illuminates when 4X4 LOW (4WD Low) is selected. 4x4 4x4 LOW Using the Control Trac 4WD system 4X4 AUTO - Provides electronically-controlled four-wheel drive with power delivered to all four wheels as required for traction. This mode is acceptable for all on-road driving but recommended when wet pavement, snow, or loose gravel conditions are expected. 4X4 HIGH (4WD High) - Provides locked four-wheel drive power to all four wheels. This mode is not intended for use on dry pavement. This mode is appropriate for severe winter and off-road conditions, such as deep snow, ice or shallow sand. 4X4 LOW (4WD Low) - Provides locked four-wheel drive power when extra power at reduced speeds is required. This mode is not recommended for use on dry pavement. Use this mode for off-road, low-speed operation or when extra power is required, such as climbing steep grades, going through deep sand, or pulling a boat out of the water. 297 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving Shifting between 4X4 AUTO (4WD Auto) and 4X4 HIGH (4WD High) • Select 4X4 AUTO (4WD Auto) or 4X4 HIGH (4WD High) at any forward speed. Note: Do not perform this operation if the rear wheels are slipping. Shifting to/from 4X4 LOW (4WD Low) 1. Bring the vehicle to a complete stop 2. Place the transmission in N (Neutral). 3. Press the desired 4WD position. • If shifting into 4x4 LOW (4WD Low), wait for the 4X4 LOW light in the instrument cluster to turn on indicating the shift is complete. • If shifting out of 4X4 LOW (4WD Low), wait for the 4X4 LOW light in the instrument cluster to turn off indicating the shift is complete. If any of the above shift conditions are not met, the shift will not occur and the message center will display the appropriate information. ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED) For the lubricant specification and refill capacity of the AWD transfer case refer to Maintenance and Specifications chapter. WARNING: If your vehicle is equipped with AWD, a spare tire of a different size than the road tires should never be used. Such a tire could make the vehicle difficult to control as well as result in damage to driveline components. WARNING: Utility and four-wheel drive vehicles are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns or abrupt maneuvers in these vehicles. Normal operation (4.0L engine vehicles only) The AWD system is always active and requires no driver input. It is capable of handling all road conditions, including street and highway driving as well as off-road conditions such as deep snow, ice or shallow sand. 298 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving Normal operation (4.6L engine vehicles only) During normal operation the AWD system is in AWD AUTO mode (AWD LOCKED will illuminate in the message center for four seconds when you first start your vehicle). The 4X4 indicator in the instrument cluster will briefly illuminate when you first start your vehicle. For instructions on selecting the AWD LOCKED mode, refer to Message center in the Instrument Cluster chapter. This mode is not intended for use on dry pavement. This mode is appropriate for severe winter or off-road conditions such as deep snow, ice or shallow sand. The use of AWD LOCKED on dry or hard surfaces may produce some noise, such as occasional clunks, but will not damage the drive system. Autolock operation (4.6L engine vehicles only) If the AWD system begins to overheat, the system will place itself in the Autolock mode: • AWD LOCKED will be displayed in the message center for four seconds and the 4x4 indicator light will illuminate in the instrument cluster. A warning chime will also sound. This condition may clear without any action being taken by the driver once the AWD system has reached a safe operating temperature. • The 4X4 indicator light in the instrument cluster will turn off when the AWD system reaches a safe operating temperature and normal AWD operation is restored. Driving off-road with truck and utility vehicles AWD and 4WD vehicles are specially equipped for driving on sand, snow, mud and rough terrain and have operating characteristics that are somewhat different from conventional vehicles, both on and off the road. How your vehicle differs from other vehicles Truck and utility vehicles can differ from some other vehicles. Your vehicle may be higher to allow it to travel over rough terrain without getting hung up or damaging underbody components. The differences that make your vehicle so versatile also make it handle differently than an ordinary passenger car. Maintain steering wheel control at all times, especially in rough terrain. Since sudden changes in terrain can result in abrupt steering wheel motion, make sure you grip the steering wheel from the outside. Do not grip the spokes. Drive cautiously to avoid vehicle damage from concealed objects such as rocks and stumps. 299 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving You should either know the terrain or examine maps of the area before driving. Map out your route before driving in the area. To maintain steering and braking control of your vehicle, you must have all four wheels on the ground and they must be rolling, not sliding or spinning. Basic operating principles • Do not use 4WD High or 4WD Low on dry, hard surfaced roads. Doing so will produce excessive noise, increase tire wear, reduce fuel economy and may damage drive components. 4WD modes are only intended for consistently slippery or loose surfaces. • Drive slower in strong crosswinds which can affect the normal steering • Be extremely careful when driving on pavement made slippery by characteristics of your vehicle. loose sand, water, gravel, snow or ice. If your vehicle goes off the edge of the pavement • If your vehicle goes off the edge of the pavement, slow down, but avoid severe brake application, ease the vehicle back onto the pavement only after reducing your speed. Do not turn the steering wheel too sharply while returning to the road surface. • It may be safer to stay on the apron or shoulder of the road and slow down gradually before returning to the pavement. You may lose control if you do not slow down or if you turn the steering wheel too sharply or abruptly. • It often may be less risky to strike small objects, such as highway reflectors, with minor damage to your vehicle rather than attempt a sudden return to the pavement which could cause the vehicle to slide sideways out of control or roll over. Remember, your safety and the safety of others should be your primary concern. WARNING: Vehicles with a higher center of gravity such as utility and four-wheel drive vehicles handle differently than vehicles with a lower center of gravity. Utility and four-wheel drive vehicles are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns, excessive speed and abrupt maneuvers in these vehicles. Failure to drive cautiously could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. 300 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving If your vehicle gets stuck If your vehicle gets stuck in mud or snow it may be rocked out by shifting between forward and reverse gears, stopping between shifts, in a steady pattern. Press lightly on the accelerator in each gear. Do not rock the vehicle if the engine is not at normal operating temperature or damage to the transmission may occur. Do not rock the vehicle for more than a few minutes or damage to the transmission and tires may occur or the engine may overheat. WARNING: Always set the parking brake fully and make sure the gearshift is latched in P (Park). Turn the ignition to the LOCK position and remove the key whenever you leave your vehicle. WARNING: If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. WARNING: Do not spin the wheels at over 35 mph (56 km/h). The tires may fail and injure a passenger or bystander. Emergency maneuvers • In an unavoidable emergency situation where a sudden sharp turn must be made, remember to avoid “over-driving” your vehicle, i.e., turn the steering wheel only as rapidly and as far as required to avoid the emergency. Excessive steering will result in less vehicle control, not more. Additionally, smooth variations of the accelerator and/or brake pedal pressure should be utilized if changes in vehicle speed are called for. Avoid abrupt steering, acceleration or braking which could result in an increased risk of loss of vehicle control, vehicle rollover and/or personal injury. Use all available road surface to return the vehicle to a safe direction of travel. • In the event of an emergency stop, avoid skidding the tires and do not attempt any sharp steering wheel movements. 301 2010 Explorer (exp) Owners Guide, 2nd Printing USA (fus) Driving WARNING: Vehicles with a higher center of gravity such as utility and four-wheel drive vehicles handle differently than vehicles with a lower center of gravity. Utility and four-wheel drive vehicles are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns, excessive speed and abrupt maneuvers in these vehicles. Failure to drive cautiously could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. • If the vehicle goes from one type of surface to another (i.e., from concrete to gravel) there will be a change in the way the vehicle responds to a maneuver (steering, acceleration or braking). Again, avoid these abrupt inputs. 4WD Systems 4WD uses all four wheels to power the vehicle. This increases traction, enabling you to drive over terrain and road conditions that a conventional two-wheel drive vehicle cannot. Power is supplied to all four wheels through a transfer case. On 4WD vehicles, the transfer case allows you to select 4WD when necessary. Information on transfer case operation and shifting procedures can be found in this chapter. Information on transfer case maintenance can be found in the Maintenance and Specifications chapter. You should become thoroughly familiar with this information before you operate your vehicle. Parking On some 4WD vehicles, when the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline. Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear. Do not leave the vehicle unattended with the transfer case in the N (Neutral) position. Always set the parking brake fully and turn off the ignition
