First you will need to decide which of the two schedules is right for your vehicle. Here is how to decide which schedule to follow:

Short Trip/City Definition

Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle:

    • Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing.
    • Most trips include extensive idling (such as frequent driving in stop-and-go traffic).
    • You frequently tow a trailer or use a carrier on top of your vehicle.
    • If the vehicle is used for delivery service, police, taxi or other commercial application.

One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down sooner.

Short Trip/City Intervals

Every 3,000 Miles (5 000 km): Engine Oil and Filter Change (or 3 months, whichever occurs first).

Every 6,000 Miles (10 000 km): Passenger Compartment Air Filter Inspection (if equipped). Tire Rotation.

Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Automatic Transmission Service (severe conditions only). Manual Transmission Fluid Change. Transfer Case Fluid Change. Differential Fluid Change. Propeller Shafts and U-Joints Inspection (or every 15 months, whichever occurs first).

Every 30,000 Miles (50 000 km): Engine Air Cleaner Filter Replacement. Passenger Compartment Air Filter Replacement (if equipped). Ignition Coil Plug Cap Inspection (or every 30 months, whichever occurs first). Engine Accessory Drive Belt Inspection (or every 30 months, whichever occurs first). Engine Cooling System Service (or every 30 months, whichever occurs first). Fuel Tank, Cap, and Lines Inspection. Fuel Filter Replacement (or every 30 months, whichever occurs first).

Every 45,000 Miles (75 000 km): Automatic Transmission Fluid Hose Inspection (or every 45 months, whichever occurs first).

Every 60,000 Miles (100 000 km): Fuel Tank Cap Gasket Replacement. Emission System Hoses Inspection. Brake Fluid Service. Spark Plug Replacement.

Every 100,000 Miles (166 000 km): Automatic Transmission Service (normal conditions).

Every 120 000 Miles (200 000 km): Evaporative Emissions Canister and Air Suction Filter Replacement (or every 120 months, whichever occurs first). Engine Accessory Drive Belt Replacement (or every 120 months, whichever occurs first).

These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages.

Long Trip/Highway Definition

Follow this scheduled maintenance only if none of the conditions from the Short Trip/City Scheduled Maintenance are true. Do not use this schedule if the vehicle is used for trailer towing, driven in a dusty area or used off paved roads. Use the Short Trip/City schedule for these conditions.

Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower.

Long Trip/Highway Intervals

Every 7,500 Miles (12 500 km): Engine Oil and Filter Change (or every 7.5 months, whichever occurs first). Tire Rotation.

Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Automatic Transmission Service (severe conditions only). Passenger Compartment Air Filter Inspection (if equipped). Propeller Shafts and U-Joints Inspection (or every 15 months, whichever occurs first).

Every 30,000 Miles (50 000 km): Engine Accessory Drive Belt Inspection (or every 30 months, whichever occurs first). Engine Cooling System Service (or every 30 months, whichever occurs first). Fuel Tank, Cap and Lines Inspection. Engine Air Cleaner Filter Replacement. Passenger Compartment Air Filter Replacement (if equipped). Ignition Coil Plug Cap Inspection (or every 30 months, whichever occurs first). Manual Transmission Fluid Change. Transfer Case Fluid Change. Differential Fluid Change. Fuel Filter Replacement (or every 30 months, whichever occurs first).

Every 45,000 Miles (75 000 km): Automatic Transmission Fluid Hose Inspection (or every 45 months, whichever occurs first).

Every 60,000 Miles (100 000 km): Fuel Tank Cap Gasket Replacement. Emission System Hoses Inspection. Spark Plug Replacement. Brake Fluid Service.

Every 100,000 Miles (166 000 km): Automatic Transmission Service (normal conditions).

Every 120,000 Miles (200 000 km): Evaporative Emissions Canister and Air Suction Filter Replacement (or every 120 months, whichever occurs first).
