Solution

1. Preparation

Gather necessary tools and materials: clean rag, funnel, and new brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Ensure the vehicle is parked on a level surface with the engine off.

2. Inspect Fluid Level

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent contaminants from entering.
Remove the cap and visually check the fluid level against the MIN and MAX markings.
If the fluid level is below the MIN mark, proceed to the next step.

3. Add Brake Fluid

Using a clean funnel, add the appropriate type of brake fluid until it reaches the MAX line.
Avoid overfilling, as this can cause fluid to overflow when the brakes are applied.
Replace and securely tighten the reservoir cap.

4. Clean Up

Wipe any spilled fluid with a clean rag, as brake fluid can damage paint and other surfaces.
Ensure all tools and materials are removed from the engine bay.
