Follow the 7,500-mile or 12-month service cycle, including oil changes, tire rotations, and brake inspections, while replacing filters, fluids, and spark plugs at their longer manufacturer-recommended intervals. The Trailblazer uses a timing chain rather than a scheduled-replacement timing belt, so replacement is generally only needed if inspection identifies wear or symptoms.
