Topping Up Windshield Washer Fluid Tesla Model S

The only reservoir into which you can add fluid is the windshield washer fluid reservoir, which is located behind the front trunk. When the level is low, a message displays on the instrument panel.

To top up the washer fluid:

  • Open the hood.
  • Clean around the filler cap before opening it to prevent dirt from entering the reservoir.
  • Open the filler cap.
  • While avoiding spilling, fill the reservoir until the fluid level is visible just below the filler neck.
  • Wipe up any spills immediately and wash the affected area with water.
  • Replace the filler cap.

Note: Some national or local regulations restrict the use of Volatile Organic Compounds (VOCs). VOCs are commonly used as antifreeze in washer fluid. Use a washer fluid with limited VOC content only if it provides adequate freeze resistance for all climates in which you drive Model S.

Note: Local regulations prohibit the use of methanol-based washer fluid. Use ethanol-based washer fluid instead.

Caution: Do not add formulated washer fluids that contain water repellent or bug wash. These fluids can cause streaking, smearing, and squeaking or other noises.

Warning: In temperatures below 40° F (4° C), use a washer fluid with antifreeze. In cold weather, using a washer fluid without antifreeze can impair visibility through the windshield.

Warning: Windshield washer fluid can irritate eyes and skin. Read and observe the instructions provided by the washer fluid manufacturer.
