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.
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 (see
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:
1. Clean the filler cap before removing it to
prevent dirt from entering the reservoir.

Fluid Reservoirs
2. Unscrew the cap and remove it.
3. Top up the reservoir to the MAX mark
using the appropriate brake fluid.
4. Replace 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.
