Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the engine and allow it to cool if it has been running.
Gather necessary tools: a clean cloth and possibly a flashlight for better visibility.

2. Check Brake Fluid Level

Locate the Reservoir:
- Identify the brake fluid reservoir cap, which is usually labeled and clear or translucent.
Inspect the Fluid Level:
- Look through the side of the reservoir to check the brake fluid level against the minimum and maximum markers.
- If the fluid level is below the minimum line, it needs to be topped up.

3. Top Up Brake Fluid (if necessary)

Choose the Correct Brake Fluid:
- Use only the type of brake fluid specified in the owner's manual (usually DOT 3 or DOT 4).
Open the Reservoir Cap:
- Carefully twist the cap counterclockwise to open it and avoid contamination.
Add Brake Fluid:
- Using a funnel, pour the brake fluid slowly until it reaches the maximum fill line without overflowing.
Replace the Cap:
- Securely close the cap by twisting it clockwise until it is tight.

4. Clean Up and Close

Wipe any spilled brake fluid with a clean cloth to prevent damage to painted surfaces.
Ensure all tools are removed from the engine bay and close the hood securely.
