Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the vehicle and engage the parking brake.
Gather tools: a clean cloth for wiping and a flashlight.

2. Locate the Brake Fluid Reservoir

Open the front trunk (frunk) of the Tesla Model 3.
Identify the brake fluid reservoir, which is usually located near the driver’s side firewall.

3. Inspect Brake Fluid Level

Remove the cap of the brake fluid reservoir carefully.
Use the flashlight to check the fluid level against the minimum and maximum marks on the reservoir.
If the fluid level is below the minimum mark, it needs to be topped up.

4. Add Brake Fluid (if necessary)

Use only the recommended brake fluid type as specified in the owner’s manual (usually DOT 3 or DOT 4).
Pour the brake fluid slowly into the reservoir, ensuring not to overfill it.
Replace and securely tighten the cap on the brake fluid reservoir.

5. Clean Up

Wipe any spilled brake fluid immediately, as it can damage paint.
Close the frunk securely.
