Solution

1. Preparation

Gather necessary tools and materials:
- Windshield washer fluid (pre-mixed or concentrated)
- Funnel (optional for easier pouring)
Ensure the vehicle is parked on a level surface and the engine is off.

2. Locate the Reservoir

Open the frunk by pulling the release lever inside the vehicle.
Lift the frunk lid to access the windshield washer fluid reservoir, which is typically located near the front of the frunk near the windshield.

3. Inspect and Refill

Remove the cap from the windshield washer reservoir.
If using concentrated washer fluid, mix it with water according to the manufacturer's instructions before pouring.
Using a funnel, if necessary, pour the washer fluid into the reservoir until it reaches the appropriate fill line (if marked) or is filled to the top.
Replace the cap securely after filling.
