Checking and Replacing Wiper
Blades
To make wiper blades easy to access, turn off
the wipers, shift Model S into Park, then use
the touchscreen to move them to the service
position. Touch Controls > Settings >
Vehicle > Service Mode > ON.
Note: Wipers automatically return to their
normal position when you shift Model S out of
Park.
Periodically check and 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.
Contaminants on the windshield, or on the
wiper blades, can reduce the effectiveness of
the wiper blades. 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 using non-abrasive
glass cleaner.
• Wipe the blades clean using isopropyl
(rubbing) alcohol or washer fluid.
If the wipers remain ineffective after cleaning,
replace the wiper blades.
For optimum performance, wiper blades
should be replaced at least once a year.
To replace wiper blades:
1. Turn off the wipers, shift Model S into
Park, then use the touchscreen to move
the wipers to the service position. Touch
Controls > Settings > Vehicle > Service
Mode > ON.
Note: Wipers must be in the OFF position
before turning on Service Mode.
2. Lift the wiper arm away from the
windshield.
3. Press the locking tab while sliding the
blade down the arm.
4. To install the new blade, align the new
blade on the wiper arm and slide it toward
the hooked end of the arm until it locks
into place.
5. Place the wiper arms with the blades
against the windshield.
Maintenance
Maintenance
If the problem persists with new blades, clean
the windshield and wiper blades using a soft
cloth or sponge and warm water with non-
detergent soap. Then, rinse the windshield
and wiper blades with clean water. The
windshield is clean when water beads do not
form.
Caution: Only use cleaning products
approved for use on automotive glass
and rubber. Inappropriate products can
cause damage or smears, and create
glare on the windshield.
Caution: Only install replacement blades
that are identical to the original blades.
Using inappropriate blades can damage
the wiper system and affect the operation
of the rain sensor.
