Checking Brake Fluid
Warning
Contact Tesla
immediately if you notice increased movement of the brake pedal or a significant loss of
brake fluid. Driving under these conditions can result in extended stopping distances or
complete brake failure.
or 
A red brake indicator on the instrument panel alerts you if the quantity of fluid in the brake reservoir
drops below the recommended level. If it displays while driving, stop as soon as
safety permits by gently applying the brakes. Do not continue driving. Contact
Tesla immediately.
Fluid Level Check
Tesla checks the brake fluid level and health at the regularly scheduled maintenance intervals. To check the fluid level yourself, park Model S on level ground. When Model S is cool, remove the maintenance panel.
Check the fluid level visually by looking at the outside marks on the side of the reservoir without removing the filler cap.
The brake fluid level should always be between the MIN and the MAX marks.
Note
Although brake fluid level drops slightly during normal use as a result
of brake pad wear, it should not drop below the MIN mark.
Topping Up the Brake Fluid
Do not top up your brake fluid. The following instructions are provided for information purposes and future reference only:
- Clean the filler cap before removing it to prevent dirt from entering the reservoir.
- Unscrew the cap and remove it.
- Top up the reservoir to the MAX mark using the appropriate brake fluid.
- Reinstall the filler cap, ensuring it is fully secured.
Warning
Only use new fluid
from a sealed air-tight container. Never use previously used fluid or fluid from a
previously opened container—fluid absorbs moisture which decreases braking
performance.
Warning
Brake fluid is
highly toxic. Keep containers sealed and out of the reach of children. In the event
of accidental consumption, seek medical attention immediately.
CAUTION
Brake fluid damages
painted surfaces. Immediately soak up any spills with an absorbent cloth and wash
the area with a mixture of car shampoo and water.
