Checking and Cleaning Wiper
Blades
Periodically clean the edge of the wiper blades 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 on the wiper blades,
can reduce the effectiveness of the wipers.
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:
• Clean the windshield and wiper blades using washer
fluid, isopropyl (rubbing) alcohol, or non-abrasive
glass cleaner approved for use on automotive glass
and rubber. Inappropriate products can cause
damage or smears, and create glare on the
windshield.
• Lift the wiper arm a short distance away from the
windshield, just far enough to access the wiper blade.
Do not lift a wiper arm beyond its intended position.
If the wipers remain ineffective after cleaning, replace
the wiper blades.
Replacing Wiper Blades
For optimum performance, replace the wiper blades at
least once a year. Replacement blades must meet the
following criteria:
• The blade on the driver's side must be 26 inches (650
mm) long and 20 inches (500 mm) long for the blade
on the passenger's side.
• Ensure the connector on the replacement blade is the
same as the original blade. Different connectors may
prevent the replacement blade from connecting to
the wiper arm on the vehicle.

4. Place a towel between the wiper arm and windshield
to avoid scratching or cracking the windshield.
5. Hold the wiper arm and press the locking tab while
sliding the blade down the arm.

it toward the end of the wiper arm until it locks into
place.

their normal position.
Cleaning Washer Jets
The position of the windshield washers is set at the
factory and should never need adjusting.
If a windshield washer becomes blocked, use a thin
strand of wire to clear any blockages from the nozzles.
WARNING:
Do not operate the washers while
cleaning Model S. Windshield washer fluid can
irritate eyes and skin. Read and observe the
washer fluid manufacturer’s instructions.
