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威 “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. indicator remains on, have your vehicle 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, indicator on can continued driving with the service engine soon 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 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.

Maintenance and Specifications

BRAKE/CLUTCH FLUID Brake and clutch (if equipped) systems are supplied from the same reservoir. 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 an underhood 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 and, if required, 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.

Maintenance and Specifications

Checking and adding manual transmission fluid (if equipped) 1. Clean the filler plug. It is located on the passenger side of the transmission. 2. Remove the filler plug and inspect the fluid level.

3. Note: For vehicles equipped with a V6 engine, the correct manual transmission fill level is at the lower edge of the filler hole. For vehicles equipped with a V8 engine, the correct manual transmission fill level is 1/2 inch (1.3 cm) below the edge of the filler hole. • Fill level for V6

• Fill level for V8

4. Add enough fluid through the filler opening to bring the fluid up to the recommended levels. 5. Install and tighten the fill plug securely.
