MAINTENANCE SCHEDULES

There are two maintenance schedules that show the required service for your vehicle.

First is Schedule "B". It is for vehicles that are operated under the conditions that are listed below and at the beginning of the schedule.

NOTE: If ANY of these apply to you then change your engine oil every 3,000 miles (5 000 km) or 3 months, whichever comes first and follow “Schedule B” of the “Maintenance Schedules” section of this manual.

NOTE: If ANY of these apply to you then flush and replace your engine coolant/anti-freeze every 102,000 miles (170 000 km) or 60 months, whichever comes first, and follow “Schedule B” of the “Maintenance Schedules” section of this manual.

NOTE: Most vehicles are operated under the conditions listed for Schedule “B.”

Second is Schedule “A”. It is for vehicles that are not operated under any of the conditions listed under Schedule “B.”

Use the schedule that best describes your driving conditions. Where time and mileage are listed, follow the interval that occurs first.

CAUTION: Failure to perform the required maintenance items may result in damage to the vehicle.

Follow this schedule if you usually operate your vehicle under one or more of the following conditions.

  • Day or night temperatures are below 0°C (32°F)
  • Stop and go driving
  • Excessive engine idling
  • Driving in dusty conditions
  • Short trips of less than 16.2 km (10 miles)

  • Trailer towing
  • Taxi, police, or delivery service (commercial service)
  • Off-road or desert driving
  • If equipped for and operated with E-85 (ethanol) fuel.

NOTE: If ANY of these apply to you then change your engine oil every 3,000 miles (5 000 km) or 3 months, whichever comes first and follow “Schedule B” of the “Maintenance Schedules” section of this manual.

NOTE: If ANY of these apply to you then flush and replace your engine coolant/anti-freeze every 102,000 miles (170 000 km) or 60 months, whichever comes first, and follow “Schedule B” of the “Maintenance Schedules” section of this manual.
