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 • 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, Motorcraft威 or 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.

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 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.

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 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 work, the vehicle may need to be serviced. Refer to On-board diagnostics (OBD-II) 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 ready for I/M testing; if the service engine soon 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. 398

Maintenance and Specifications

POWER STEERING FLUID Check the power steering fluid. Refer to scheduled maintenance information. 1. Start the engine and let it run until it reaches normal operating temperature (the engine coolant temperature gauge indicator will be near the center of the normal area between H and C). 2. While the engine idles, turn the steering wheel left and right several times. 3. Turn the engine off. 4. Check the fluid level in the reservoir. It should be between the MIN and MAX lines. Do not add fluid if the level is in this range. 5. If the fluid is low, add fluid in small amounts, continuously checking the level until it reaches the range between the MIN and MAX lines. Be sure to put the cap back on the reservoir. Refer to Maintenance product specifications and capacities in this chapter for the proper fluid type.

BRAKE FLUID The fluid level will drop slowly as the brakes wear, and will rise when the brake components are replaced. Fluid levels between the MIN and MAX lines are within the normal operating range; there is no need to add fluid. If the fluid levels are outside of the normal operating range, the performance of the system could be compromised; seek service from your authorized dealer immediately.

TRANSMISSION FLUID

Checking automatic transmission fluid The automatic transmission does not have a transmission fluid dipstick. Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. However, the fluid level should be checked if the transmission is not working properly, (i.e., if the transmission slips or shifts slowly) or if you notice some sign of fluid leakage. Transmission fluid should be checked by an authorized dealer. If required, fluid should be added by an authorized dealer. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.

AIR FILTER Refer to scheduled maintenance information for the appropriate intervals for changing the air filter element. When changing the air filter element, use only the air filter element listed. Refer to Motorcraft威 part numbers in this chapter.

WARNING: To reduce the risk of vehicle damage and/or personal burn injuries do not start your engine with the air

cleaner removed and do not remove it while the engine is running.

Changing the air filter element 1. Locate the mass air flow sensor electrical connector on the air outlet tube. This connector will need to be unplugged.
