Solution

1. Preparation

Gather necessary tools: a clean cloth, funnel, and new brake fluid (if needed).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Locate and Inspect the Brake Fluid Reservoir

Identify the brake fluid reservoir, which is a translucent plastic container with a cap labeled "brake fluid."
Check the fluid level against the "MIN" and "MAX" marks on the side of the reservoir. If the level is below "MIN," the fluid needs to be topped up.

3. Add Brake Fluid (if necessary)

Remove the cap of the brake fluid reservoir carefully. Wipe the cap and surrounding area with a clean cloth to prevent contamination.
Using a funnel, add the appropriate type of brake fluid (typically DOT 4 for most modern vehicles) until it reaches the "MAX" line.
Replace the cap securely, ensuring it clicks into place.

4. Clean Up and Final Checks

Wipe any spills with a clean cloth, as brake fluid can damage paint and plastic surfaces.
Close the hood securely.
