Windshield washer fluid

To ensure proper cleaning of the windshield
and to prevent freezing in cold weather,
check the reservoir level weekly. If needed,
top up with windshield washer fluid.
Caution: Always follow the directions
provided by the windshield washer fluid
manufacturer. If the windshield washer fluid
requires dilution, carefully follow the
manufacturer's directions and mix the
recommended quantities of water and
windshield washer fluid in a separate
container before topping up the reservoir.
Undiluted windshield washer fluid can
discolor the vehicle's paint.

Fluid level check
Check the fluid level weekly with the vehicle
on level ground and when the vehicle is cool.
The fluid level can be checked visually
through the side of the reservoir without
removing the filler cap. The fluid level should
be between the MIN and the MAX marks.
If the level drops significantly, a leak may
exist. Contact Tesla Motors before using the
vehicle.
Topping up the coolant
The cooling system for your vehicle
contains a propylene glycol (PG) based
antifreeze. Compared to conventional
ethylene glycol based antifreezes, propylene
glycol is less toxic, safer for children, pets and
wildlife, and safer for the environment.
Top-up to the MAX mark with one of the
following recommended solutions:
• a 50/50 mix of water and Havoline®
Extended Life Antifreeze Coolant-PG
• pre-mixed Sierra Antifreeze Coolant-PG,
or a 50/50 mix of water and full-strength
Sierra Antifreeze Coolant-PG
Caution: Do not mix with any other type
of antifreeze! In an emergency, top up
with distilled water only and be aware of the
reduced frost and corrosion protection.
Antifreeze contains important corrosion
inhibitors. Maintain the antifreeze content of
the coolant between 50% and 60% year
round. Do not exceed 60% or cooling
efficiency will be impaired.
Ensure cap is replaced and fully tightened
after topping up.
Note: Change coolant every four years,
regardless of mileage.
