Solution

1. Preparation

Gather necessary tools: clean rag, flashlight (optional), and brake fluid (DOT 3 or DOT 4).
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Locate the Brake Fluid Reservoir

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

3. Inspect the Brake Fluid Level

Wipe the area around the reservoir cap with a clean rag to avoid dirt contamination.
Carefully remove the reservoir cap by twisting it counterclockwise.
Check the brake fluid level against the markings on the side of the reservoir. The fluid should be between the "MIN" and "MAX" lines.

4. Add Brake Fluid (if necessary)

If the fluid is below the "MIN" line, add the correct type of brake fluid (DOT 3 or DOT 4) until it reaches the "MAX" line.
Do not overfill the reservoir.

5. Replace the Reservoir Cap

After adding fluid, securely replace the reservoir cap by twisting it clockwise until it is tight.
Ensure there is a good seal to prevent moisture contamination in the brake fluid.

6. Clean Up and Close the Hood

Wipe any spilled fluid from the reservoir area with a clean rag.
Close the hood securely.
