- Review fluid levels

### 15,000-30,000 Miles

- Oil and filter change
- Tire rotation
- Air filter inspection

### 60,000 Miles

- Transmission fluid (check manual-some don't need service)
- Spark plugs (on some models)
- Coolant top-up or flush

### 90,000-100,000 Miles

- Major fluid inspection and potential replacement
- Brake system check
- Battery test
