Solution

1. Preparation

Gather Tools: You may need a clean cloth or paper towel for cleaning purposes.
Safety Precautions: Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Clean

Clean Area Around Reservoir: Wipe the area surrounding the brake fluid reservoir with a clean cloth to prevent contamination during the opening.
Open Reservoir Cap: Carefully remove the cap from the brake fluid reservoir. Ensure no dirt or debris falls into the reservoir.

3. Check Fluid Level

Evaluate Fluid Level: Look at the fluid level against the minimum and maximum indicators on the reservoir. If the level is below the minimum, it needs to be topped off.
Assess Fluid Condition: If the fluid appears dark or contaminated, consider a brake fluid flush.

4. Top Off Brake Fluid (if needed)

Add Appropriate Brake Fluid: Use only the recommended brake fluid type (usually DOT 3 or DOT 4) for Tesla vehicles. Pour the fluid carefully into the reservoir until it reaches the maximum level.
Secure Cap: Replace the reservoir cap tightly after checking or topping off the fluid.
