Solution

1. Preparation

Tools Required: None required for fluid level check.
Safety Warnings: Ensure the vehicle is parked on a level surface.

2. Check Windshield Washer Fluid

Locate the windshield washer fluid reservoir under the hood.
Remove the cap and visually inspect the fluid level.
If low, fill with the appropriate windshield washer fluid until it reaches the indicated level.

3. Check Brake Fluid Level

Locate the brake fluid reservoir, typically near the back of the engine bay on the driver's side.
Remove the cap and check the fluid level against the markings on the side of the reservoir.
If the fluid is low, add brake fluid that meets Tesla specifications (DOT 3 or DOT 4) until the correct level is reached.

4. Check Coolant Level

Locate the coolant reservoir, usually a translucent tank with minimum and maximum markings.
Ensure the vehicle is cool, then check the coolant level.
If the coolant is below the minimum line, add a mixture of Tesla-approved coolant and distilled water to the appropriate level.
