Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools: a clean cloth and a funnel (if adding fluid).

2. Inspect Brake Fluid Level

Locate the brake fluid reservoir cap and check the current fluid level against the "MIN" and "MAX" indicators.
If the fluid level is below the "MIN" mark, proceed to add brake fluid.

3. Add Brake Fluid (if necessary)

Remove the cap of the brake fluid reservoir by twisting it counterclockwise.
Using a funnel, carefully add the appropriate type of brake fluid (DOT 3 or DOT 4, as specified in the vehicle manual) until it reaches the "MAX" line.
Avoid overfilling the reservoir.

4. Reassemble

Replace the reservoir cap securely and twist it clockwise until it is tight.
Clean any spilled brake fluid from the surrounding area to prevent damage to vehicle surfaces.

5. Final Check

Close the frunk securely.
Check the brake pedal feel before driving to ensure proper brake response.
