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 Y.
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.
