1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect and Repair Exhaust System

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Visually inspect the exhaust system from the engine to the tailpipe for any cracks, holes, or rusted areas.
- If leaks are found, mark the locations for repair.
- Use exhaust sealant or replace damaged sections of the exhaust pipe as needed.
- Reinstall any disconnected components and secure all clamps properly.

3. Replace Cabin Air Filter

Sub-steps:
- Locate the cabin air filter compartment (typically behind the glove box).
- Remove the glove box to access the filter.
