Solution

1. Preparation

Gather necessary tools: Clean rag, flashlight (optional).
Ensure the vehicle is in a safe position with the engine off.

2. Locate and Open the Brake Fluid Reservoir

Identify the brake fluid reservoir on the driver's side of the engine compartment.
Remove the reservoir cap by twisting it counterclockwise. Ensure it is done gently to avoid spillage.

3. Check Brake Fluid Level

Inspect the fluid through the transparent reservoir. The fluid level should be between the "MIN" and "MAX" marks.
If the fluid is below the "MIN" mark, it is necessary to add fluid.

4. Add Brake Fluid (if needed)

Use only the recommended brake fluid type (usually DOT 3 or DOT 4 for Toyota vehicles).
Pour the brake fluid slowly into the reservoir until it reaches the "MAX" mark.
Avoid overfilling, which can cause pressure issues in the brake system.

5. Resecure the Reservoir Cap

Clean the cap and the area around the reservoir to ensure there are no contaminants present.
Replace the cap by twisting it clockwise until secure.
