Solution

1. Preparation

Gather necessary tools: a clean cloth or paper towel for wiping.
Ensure the vehicle is parked on a level surface for accurate reading.

2. Locate the Brake Fluid Reservoir

Open the hood of the Tesla Model 3 by pulling the hood release lever inside the vehicle.
Secure the hood with the prop rod if necessary.
Find the brake fluid reservoir, which is a translucent plastic container with a cap, often labeled with a brake symbol.

3. Check Fluid Level

Visually inspect the fluid level through the translucent walls of the reservoir.
Ensure the fluid level is between the "MIN" and "MAX" markings on the reservoir.
If the fluid level is below the "MIN" mark, it should be topped up.

4. Top Up Brake Fluid (if necessary)

Remove the cap of the brake fluid reservoir carefully.
Use only the recommended brake fluid type as specified in the owner's manual (typically DOT 3 or DOT 4).
Pour brake fluid slowly into the reservoir until it reaches the "MAX" level, ensuring not to overfill.
Replace the cap securely after topping up.
