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.
