MAINTENANCE SCHEDULES - DIESEL ENGINES

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.

  • Day or night temperatures are below 0°C (32°F).
  • Stop and go driving.
  • Extensive engine idling.
  • Driving in dusty conditions.
  • Short trips of less than 16.2 km (10 miles).
  • More than 50% of your driving is at sustained high speeds during hot weather, above 32°C (90°F).
  • Trailer towing.
  • Taxi, police, or delivery service (commercial service).
  • Off-road or desert driving.

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.

    At Each Stop for Fuel

  • Check the engine oil level about 5 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the accuracy of the oil level reading. Add oil only when the level is at or below the ADD or MIN mark.
  • Check the windshield washer solvent, add as required.

    Once a Month

  • Check the tire pressure and look for unusual wear or damage.
  • Inspect the battery, clean and tighten the terminals as required.
  • Check the fluid levels of engine coolant/anti-freeze deaeration bottle, brake master cylinder, and transmission, and add as needed.
  • Check all lights and all other electrical items for correct operation.

    At Each Oil Change

  • Change the engine oil filter.
  • Inspect the exhaust system.
  • Inspect brake hoses.
  • Check the engine coolant/anti-freeze level, hoses, and clamps.
  • Inspect engine accessory drive belts. Replace as necessary.
  • Inspect for the presence of water in the fuel filter/water separator unit.

Schedule “B” - Diesel Engines

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

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