Passenger Compartment Air Filter The passenger compartment air filter removes certain particles from the air, including pollen and dust particles. Reductions in airflow, which may occur more often in dusty areas, indicate that the filter may need to be replaced early. The filter should be replaced as part of the routine scheduled maintenance. See Scheduled Maintenance on page 7-4 for more information. To check or replace the air filter, do the following: 1. With the hood open, unlatch and remove the access panel. The passenger compartment air filter and access panel are located on the passenger side of the engine compartment near the battery. See Engine Compartment Overview on page 6-12 for more information on location. 2. Pull the old filter out of the housing. 3. Insert the new filter into the housing. 4. Reinstall the air filter access panel. Warning Lights, Gages, and Indicators Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gages could prevent injury. Warning lights come on when there may be or is a problem with one of the vehicle's functions. Some warning lights come on briefly when the engine is started to indicate they are working. Gages can indicate when there may be or is a problem with one of the vehicle's functions. Often gages and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gages shows there may be a problem, check the section that explains what to do. Follow this manual's advice. Waiting to do repairs can be costly and even dangerous. 3-41
