Topping Up Windshield Washer
Fluid
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
touchscreen.
To top up the washer fluid:
1. Open the hood.
2. Clean around the filler cap before opening
it to prevent dirt from entering the
reservoir.
3. Open the filler cap.
4. While avoiding spilling, fill the reservoir
until the fluid level is visible just below the
filler neck.
5. Wipe up any spills immediately and wash
the affected area with water.
6. 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 3.
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 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.
