Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Open the engine compartment and secure it with the prop rod.
Gather necessary tools: clean cloth, flashlight (optional).

2. Locate and Inspect the Brake Fluid Reservoir

Identify the brake fluid reservoir, which is typically located near the driver's side of the engine bay, near the back of the engine compartment.
Use a flashlight if necessary to get a better view.
Clean the area around the reservoir cap with a cloth to prevent contamination.

3. Check Brake Fluid Level

Remove the cap of the brake fluid reservoir by twisting it counter-clockwise. Be careful not to introduce dirt or debris into the reservoir.
Visually check the fluid level against the markings on the side of the reservoir; it should be between the "MIN" and "MAX" lines.
If the fluid is below the "MIN" line, it needs to be topped off.

4. Assess Fluid Condition

Inspect the color and clarity of the brake fluid. It should be a clear, light amber color. If it appears dark or murky, it should be replaced.
If required, proceed to replace the brake fluid (instructions for fluid replacement can follow in a separate guide).

5. Reassemble

After checking the fluid level and condition, replace the cap on the reservoir securely by twisting it clockwise.
Close the engine compartment securely.
