1. Preparation

Gather necessary tools and parts.

- Fill the engine with the manufacturer-recommended oil (e.g., VW 502 00).
Fluid Checks:
- Top off brake fluid if low, using the correct type (DOT 4).
- Ensure coolant is at the proper level, topping off with G12 coolant if needed.
Tire Maintenance:
- Check tire pressure and inflate to the recommended PSI (usually found on the driver’s side door jamb).
- Inspect tires for wear and replace if necessary.

3. Reset Maintenance Light

Reconnect the battery.
Turn the ignition to the ON position without starting the engine.
