Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-14 for the location of the engine air cleaner/filter. Notice: If you spray water into the engine air cleaner/filter intake and water enters the engine air cleaner/filter housing, you could damage your vehicle's engine. The repairs would not be covered by your warranty. Do not spray water into the engine air cleaner/filter intake and/or housing. If you are cleaning the vehicle with the hood open, take care not to spray water directly near the filter opening of the air cleaner, as shown in the illustration, as this could damage the vehicle's engine. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace them at the first oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance on page 6-4 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. 5-28
