Compiled from the manufacturer’s published maintenance information. Always confirm intervals with your owner’s manual — towing, dusty roads and short trips can mean services are due sooner.
Miles or time — whichever comes first
An interval like “10,000 miles or 12 months” gives two deadlines, and the service is due at whichever arrives first. Drive a lot and the miles come first; drive little and the calendar does. MaintainAhead learns how fast you put on miles and tells you which date that is for your Outback.
