Maintenance and Specifications

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.

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 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 cap may not have been securely tightened. See Fuel filler cap in this chapter. 4. Driving through deep water—the electrical system may be wet.

Maintenance and Specifications

These temporary malfunctions can be corrected by filling the fuel tank with good quality fuel, properly tightening the fuel cap 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. If the Service engine soon 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 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 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 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.

Maintenance and Specifications

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. POWER STEERING FLUID Check the power steering fluid. Refer to the scheduled maintenance guide for the service interval schedules.

Check the fluid level when it is at ambient temperature, 20° – 80° F (-7° – 25° C): 1. Check the fluid level on the dipstick. It should be between the arrows in the FULL COLD range. Do not add fluid if the level is within this range. 2. If the fluid level is low, start the engine. 3. While the engine idles, turn the steering wheel left and right several times. 4. Turn the engine off.

WARNING: For E-350 and E-450 vehicles with the Hydro-Boost Brake System, do not press the brake pedal after the engine has

been turned off. Pressing the brake pedal after the engine has been turned off will give a false power steering fluid level reading.

5. Recheck the fluid level on the dipstick. Do not add fluid if the level is between the arrows in the FULL COLD range. 6. If the fluid is low, add fluid in small amounts, continuously checking the level until it reaches the FULL COLD range. Be sure to put the dipstick back in the reservoir. Refer to Maintenance product specifications and capacities in this chapter for the proper fluid type.

BRAKE FLUID • E-150/E-350 Single Rear Wheel

• E-350/E-450 Dual Rear Wheel

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.

Maintenance and Specifications

DRIVELINE UNIVERSAL JOINT AND SLIP YOKE Your vehicle may be equipped with universal joints that require lubrication. Refer to the scheduled maintenance information for maintenance intervals. If the original universal joints are replaced with universal joints equipped with grease fittings, lubrication will also be necessary.

TRANSMISSION FLUID

Checking automatic transmission fluid (if equipped) 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. Automatic transmission fluid expands when warmed. To obtain an accurate fluid check, drive the vehicle until it is at normal operating temperature (approximately 20 miles [30 km]). If your vehicle has been operated for an extended period at high speeds, in city traffic during hot weather or pulling a trailer, the vehicle should be turned off for about 30 minutes to allow fluid to cool before checking. 1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating temperature. 2. Park the vehicle on a level surface and engage the parking brake. 3. With the parking brake engaged and your foot on the brake pedal, start the engine and move the gearshift lever through all of the gear ranges. Allow sufficient time for each gear to engage. 4. Latch the gearshift lever in P (Park) and leave the engine running. 5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If necessary, refer to Identifying components in the engine compartment in this chapter for the location of the dipstick. 6. Install the dipstick making sure it is fully seated in the filler tube. 7. Remove the dipstick and inspect the fluid level. The fluid should be in the designated area for normal operating temperature or ambient temperature.
