Fluid Checks and Replacements
- Check and top off coolant levels if necessary, using the recommended coolant type.
- Inspect and replace brake fluid if it appears dirty or is due for a change (typically every 2 years).
Inspect Filters
- Replace the engine air filter and cabin air filter if they are dirty or overdue according to the service schedule.
