Solution

1. Preparation

Gather necessary tools such as a flashlight for better visibility.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Access the Brake Fluid Reservoir

Open the hood of the vehicle.
Locate the brake fluid reservoir, which is typically near the back of the engine bay on the driver's side.
Clean the area around the reservoir cap to prevent contamination.

3. Check Fluid Level

Remove the reservoir cap carefully, avoiding any spills.
Visually inspect the fluid level against the "MIN" and "MAX" markings on the reservoir.
- If the fluid is below the "MIN" mark, it needs to be topped off.
Assess the fluid condition; it should be clear or slightly amber. If it appears dark or murky, it should be replaced.

4. Top Off Brake Fluid (if necessary)

Use only the recommended brake fluid type (usually DOT 3 or DOT 4, check the owner’s manual for specifics).
Pour the brake fluid carefully into the reservoir until it reaches the "MAX" line.
Replace the reservoir cap securely.

5. Final Inspection

Check for any visible leaks around the brake lines and calipers.
Close the hood securely after finishing.
