Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Brake Fluid Level

Step 1: Open the frunk and locate the brake fluid reservoir.

Step 3: If the fluid is below the "MIN" mark, proceed to add brake fluid.

3. Add Brake Fluid

Step 1: Clean the area around the reservoir cap to prevent contamination.
Step 2: Carefully remove the reservoir cap.
Step 3: Using a funnel, add the recommended type of brake fluid (typically DOT 3 or DOT 4) until the fluid reaches the "MAX" mark.
Step 4: Replace the reservoir cap securely.

4. Clean Up

Step 1: Wipe any spilled brake fluid with a clean cloth, as it can damage vehicle paint.
Step 2: Dispose of any used materials properly.
