Regular vs. Severe Maintenance

In order to maintain your vehicle in its best condition, it is critical that you adhere to the appropriate maintenance schedule. Mitsubishi publishes two required maintenance schedules that should be applied based on whether your vehicle is driven under "severe" (referred to as Schedule 1) or "regular" (referred to as Schedule 2) conditions. These schedules list the required service for your vehicle and should be selected as follows:

Select the Severe Maintenance (Schedule 1) if you drive your vehicle under any of the following conditions:

  • Driving on dusty, rough, muddy, or salt-spread roads
  • Towing, police, taxi, or commercial operation
  • Extensive idling and/or low-speed operation
  • Repeated short-trip operation at freezing temperatures (engine not thoroughly warmed up)
  • Extensive use of brakes while driving
  • Driving in sandy areas
  • More than 50% operation in heavy city traffic during hot weather above 90 degrees Fahrenheit (32 degrees Celsius)

If any of these conditions apply to your driving, then it is critical that you adhere to the Severe Maintenance Schedule for your vehicle. You should only follow the Regular Maintenance Schedule if your vehicle is not operated under any of the conditions listed above. Under no condition, on any vehicle, should oil change intervals exceed 7,500 miles or 6 months, whichever comes first.

Driving conditions around the country result in the majority of drivers needing to follow the Severe Maintenance Schedule. For specific details and a list of additional required maintenance, please refer to your Owner's Warranty and Maintenance Manual.
