- Frequent driving in mountainous areas: Involving prolonged uphill or downhill driving.
- Extended periods of idling or low-speed operation: Such as in heavy city traffic.
- Driving in very hot or very cold climates.
For these conditions, consider the following adjustments:
- Oil & Filter Change: Every 3,750 miles or 3.75 months.
- Tire Rotation: Every 3,750 miles.
- Engine Air Filter: Inspect and replace more frequently, every 15,000 miles or sooner.
- Cabin Air Filter: Replace every 7,500 miles or 6 months.
