Solution

1. Preparation

Gather tools: Clean rag or paper towel.
Ensure the vehicle is turned off and parked on a level surface.

2. Locate the Brake Fluid Reservoir

Open the hood of the vehicle.
Locate the brake fluid reservoir; it is typically found near the back of the engine bay, close to the driver's side.

3. Inspect the Fluid Level

Check the external markings on the reservoir for minimum and maximum level indicators.
If the fluid is below the minimum line, proceed to the next step.

4. Add Brake Fluid (if necessary)

Remove the reservoir cap slowly to avoid contamination.
Use a funnel to pour the appropriate type of brake fluid (DOT 3 or DOT 4) into the reservoir until it reaches the maximum level.
Replace the cap securely after adding fluid.

5. Clean Up

Wipe any spilled brake fluid with a clean rag or paper towel.
Ensure that all tools are removed from the engine bay and the hood is closed properly.
