Solution

1. Preparation

Gather necessary tools: clean cloth, flashlight (if needed).
Ensure the vehicle is parked safely and the engine is off.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, which is typically a translucent plastic container marked with "brake fluid."
Use a flashlight if necessary to see inside the reservoir clearly.
Check the fluid level against the minimum and maximum markings on the side of the reservoir:
- If the fluid level is below the minimum mark, it needs to be topped off.

3. Top Off Brake Fluid (if necessary)

If the fluid is low, remove the reservoir cap carefully.
Use a funnel to add the correct type of brake fluid (usually DOT 3 or DOT 4, refer to the owner’s manual for specifics).
Fill to the maximum line, ensuring not to overfill.
Replace the reservoir cap securely.

4. Clean Up

Wipe any spilled brake fluid immediately with a clean cloth, as it can damage painted surfaces.
Dispose of any used cloths or materials per local regulations.
