Windshield Wiper Blade, Jets and Fluid

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 powered frunk liner. When the level is low, a message displays on the touchscreen.

To top up the washer fluid:

Open the powered frunk.
Use a microfiber cloth to 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. The reservoir has a total capacity of 4.2 liters.
Wipe up any spills immediately and wash the affected area with water.
Close the filler cap.

CAUTION

Some national or local regulations restrict the use of Volatile Organic Compounds (VOCs). VOCs are commonly used as freeze protection 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 Cybertruck.

CAUTION

Use only ethanol-based 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. Untreated pure water expands to ice when freezing, which may result in damage.

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 -32° F (0° 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.

Cleaning the Wiper Blade

Periodically clean the edge of the wiper blade and check the rubber for cracks, splits, and roughness. If damaged, replace the blade immediately to prevent damage to the glass and improve visibility.

Contaminants on the windshield or wiper blade can reduce the effectiveness of the wiper. Contaminants include ice, wax spray from car washes, washer fluid with bug and/or water repellent, bird droppings, tree sap, and other organic substances.

Follow these guidelines for cleaning:

Lift the wiper arm a short distance away from the windshield, just far enough to access the wiper blade. Do not lift the wiper arm beyond its intended position.
Place a towel between the wiper arm and windshield to avoid scratching or cracking the windshield.
Clean the windshield and wiper blade using washer fluid or non-abrasive glass cleaner approved for use on automotive glass and rubber.
CAUTION
Inappropriate products can cause damage or smears and create glare on the windshield.
Gently place the wiper blade back onto the windshield.
Test the wiper blade again. If the wiper remains ineffective after cleaning, replace the wiper blade.

Note

An ineffective wiper can lead to reduced visibility for the front windshield cameras, which may lead to degraded performance or unavailability of Autopilot features. For more information, see Cameras and refer to Autopilot Limitations and Warnings.

Replacing the Wiper Blade

For optimum performance, replace the wiper blade at least once a year. You can purchase a replacement wiper blade on the Tesla Shop.

CAUTION

Only install a replacement blade that is identical to the original blade. Using an inappropriate blade can damage the wiper system and windshield.

To replace the wiper blade:

Shift into Park and turn off the wiper. Ensure the wiper setting is Off and not in Auto, because the wiper blade may still sweep if there is any liquid detected on the windshield.
Place a towel between the wiper arm and windshield to avoid scratching or cracking the windshield.
Lift the wiper arm a short distance away from the windshield, just far enough to access the wiper blade.
CAUTION
Wiper blade does not lock into a lifted position. Do not lift the wiper arm beyond its intended position or drop it onto the windshield.
While holding the wiper arm, press the locking tab, then slide the blade away from the arm. Set the wiper blade next to the wiper arm.
Disconnect the washer hose from the wiper blade by pulling the hose from the barb fitting.
Connect the new washer hose to the barb fitting on the new wiper blade.
Align the new wiper blade on the wiper arm and slide it toward the base of the wiper arm until it locks into place.
Ensure the wiper blade is fully secured by lightly pushing and pulling on the blade. The blade should not jostle or move around.
CAUTION
Ensure the new blade is locked in place and does not move. If not locked in place (you can hear and feel a "click"), the wiper blade may come off during use, resulting in serious damage.
Remove the towel and gently place the wiper blade against the windshield.

Washer Jets

The windshield washer fluid sprays from nozzles along the length of the wiper blade. You cannot adjust them. If a windshield washer nozzle becomes blocked, use a thin strand of wire to clear any blockages.

If the blade is not dispensing washer fluid, make sure there is enough wiper fluid in the reservoir and refill if needed. If this issue still persists, check the hose connection between the arm and blade for any leaks, kinks, or disconnections.

Warning

Do not operate the washers while cleaning Cybertruck. Windshield washer fluid can irritate eyes and skin. Read and observe the washer fluid manufacturer’s instructions for safe handling.
