Solution

1. Preparation

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

2. Locate the Brake Fluid Reservoir

Open the hood and support it securely.
Find the brake fluid reservoir typically located near the back of the engine bay, on the driver’s side.

3. Check Fluid Level

Visually inspect the fluid level through the reservoir's transparent body.
If the fluid is below the minimum mark, proceed to the next step.

4. Add Brake Fluid (if necessary)

Tools Required: Funnel (optional), clean rag.
Remove the cap of the brake fluid reservoir.
Use a clean funnel to pour in the appropriate type of brake fluid (usually DOT 4).
- Note: Avoid contamination of the fluid by not allowing dirt or debris to enter the reservoir.
Fill the reservoir to the maximum mark without overfilling.
Wipe any spills with a clean rag.

5. Recheck and Close

Recheck the fluid level after adding.
Ensure the cap is securely closed to prevent moisture contamination.
