Here is how to decide which of the two schedules to follow:

Short Trip/City Definition

Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for the 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.
    • 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 the 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): Tire Rotation.

Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Passenger Compartment Air Filter Replacement. Drive Belt(s) Inspection.

Every 30,000 Miles (50 000 km): Engine Air Cleaner Filter Replacement. Spark Plug Replacement. EVAP System Service. PCV System Service. Restraint System Check.

Every 37,500 Miles (60 000 km): Automatic Transmission Fluid Change (severe service only).

Every 42,000 Miles (70 000 km): Engine Oil Pan Drain Plug Washer Replacement.

Every 60,000 Miles (100 000 km): Spark Plug Wire Replacement. Timing Belt Replacement. EVAP System Solenoid Valve Replacement.

Every 90,000 Miles (150 000 km): Fuel Filter Replacement.

Every 150,000 Miles (240 000 km): Cooling System Service.

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 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 12 months, whichever occurs first). Tire Rotation.

Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection. Passenger Compartment Air Filter Replacement. Drive Belt(s) Inspection.

Every 30,000 Miles (50 000 km): Engine Air Cleaner Filter Replacement. Spark Plug Replacement. EVAP System Service. PCV System Service. Restraint System Check.

Every 37,500 Miles (60 000 km): Automatic Transmission Fluid Change (severe service only).

Every 60,000 Miles (100 000 km): Spark Plug Wire Replacement. Timing Belt Replacement. EVAP System Solenoid Valve Replacement.

Every 90,000 Miles (150 000 km): Fuel Filter Replacement. Engine Oil Pan Drain Plug Washer Replacement.

Every 150,000 Miles (240 000 km): Cooling System Service.
