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 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.
- Reinstall the filler cap.
CAUTION
Use only windshield
washer fluid meant for automotive vehicles. Using other substances, such as untreated
water, can result in bacterial growth within the climate control system resulting in
odor or potential damage that is not covered by warranty.
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.
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.
