The only reservoir into which you can add fluid is the windshield washer fluid reservoir, which is located behind the powered frunk liner. When the level is low, a message displays on the touchscreen.

To top up the washer fluid:

1. Acquire the appropriate washer fluid, as detailed in the Owner's Manual.
2. Open the powered frunk.
3. Use a microfiber cloth to clean around the filler cap before opening it to prevent dirt from entering the reservoir.
4. Open the filler cap.
5. While avoiding spilling, fill the reservoir until the fluid level is visible just below the filler neck. The reservoir has a total capacity of 4.2 liters.

   

6. Wipe up any spills immediately and wash the affected area with water.
7. Close the filler cap.
