Passenger Compartment Air Filter (If Equipped) Your vehicle may be equipped with a passenger compartment air filter. The filter is located under the instrument panel, below the glove compartment. Your vehicle may or may not be equipped with an access panel. To replace the passenger compartment air filter, do the following: 1. If your vehicle has an access panel, remove the bolts on it and set the panel aside. If your vehicle does not have the access panel, skip this step. 2. Next, pull downward on the filter retaining bracket. 3. Remove the air filter by pulling downward on the element. Remove the second portion of the air filter by sliding it towards the rear of the vehicle and then pulling downward. 4. Install the new filter by reversing the steps listed previously. Be sure to follow any instructions that may be included in the replacement filter package. Because this procedure can be a little difficult, you may choose to have it done at your dealer's service department. Refer to the Maintenance Schedule to determine when to replace the passenger compartment air filter. See "Scheduled Maintenance" in the Index. 6-23
