Solution

1. Preparation

Gather necessary tools: clean rag, flashlight (optional).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Locate the Brake Fluid Reservoir

Open the hood of the vehicle.
Identify the brake fluid reservoir, typically located near the back of the engine bay, close to the driver's side.

3. Inspect the Brake Fluid Level

Use a flashlight if needed to see clearly.
Check the fluid level; it should be between the "MIN" and "MAX" marks on the reservoir.
If the level is below the "MIN" mark, brake fluid needs to be added.

4. Add Brake Fluid (if necessary)

Use only the manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4, as specified in the owner's manual).
Remove the reservoir cap carefully to prevent contamination.
Add brake fluid slowly until it reaches the "MAX" mark. Avoid overfilling.
Replace and securely tighten the reservoir cap.
