Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Wear gloves to prevent skin contact with brake fluid, as it can damage paint and other surfaces.

2. Open the Frunk

Use the key fob or touchscreen to unlock and open the frunk.
Secure the frunk open with the provided support rod if necessary.

3. Locate the Brake Fluid Reservoir

Identify the brake fluid reservoir located on the driver's side near the back of the frunk.
Remove any debris or covers that may obstruct access to the reservoir.

4. Check Fluid Level

Observe the brake fluid level in the reservoir; it should be between the "MIN" and "MAX" markings.
If the fluid is below the "MIN" line, it needs to be topped off.

5. Top Off Brake Fluid (if necessary)

Use only the recommended brake fluid type (usually DOT 3 or DOT 4; consult the owner's manual).
Carefully remove the reservoir cap and add brake fluid until it reaches the "MAX" line.
Replace the cap securely after topping off.

6. Clean Up

Wipe any spilled brake fluid immediately with a clean cloth.
Ensure that all tools are removed from the frunk before closing.
