Maintenance and Specifications 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 indicator blinks eight times, it means that the vehicle is not ready for I/M testing; if the indicator stays on solid, it means that the vehicle is ready for I/M testing. The OBD-II system is designed to check the emission control system during normal driving. A complete check may take several days. If the vehicle is not ready for I/M testing, the following driving cycle consisting of mixed city and highway driving may be performed: 15 minutes of steady driving on an expressway/highway followed by 20 minutes of stop-and-go driving with at least four 30 second idle periods. Allow the vehicle to sit for at least eight hours without starting the engine. Then, start the engine and complete the above driving cycle. The engine must warm up to its normal operating temperature. Once started, do not turn off the engine until the above driving cycle is complete. If the vehicle is still not ready for I/M testing, the above driving cycle will have to be repeated. POWER STEERING FLUID Refer to the scheduled maintenance information for the service interval schedules. If adding fluid is necessary, use only MERCON ATF. 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. 249 2007 Zephyr (378) Owners Guide (post-2002-fmt) USA (fus)
