Scheduled Maintenance—Emissions

The Emission System Required Maintenance Schedule lists the items required to maintain the vehicle emission systems at levels determined by the Federal Government (Environmental Protection Agency). Also printed is an index to a number of Maintenance Procedures, each of which is related to an item listed on the maintenance schedule. Use these procedures to perform the required emission system maintenance items listed on the maintenance schedules.

• Maintenance service adjustments must conform to specifications contained here, listed in the Specifications Manual or shown on the Vehicle Emissions Control Information Decal, or the emissions system may become inoperative.
• As a safety precaution, before starting the engine to perform maintenance, ensure the shift control selector is in PARK (automatic transaxle) or NEUTRAL (manual transaxle), the parking brake is set and the wheels are blocked.
