Ventilation
Outside air is drawn into Model S through the
grill in front of the windshield. Keep the grill
clear of obstructions such as leaves and snow.
To direct the
flow of air inside Model S, move
the interior vents up, down, or from side to
side.
Note: You can direct the outer face level vents
toward the side windows to help defrost or
defog them.
Cabin Air Filter
Model S has an air
filter that prevents pollen,
industrial fallout, road dust and other particles
from entering through the vents. Tesla
replaces the air
filter at the regularly
scheduled maintenance intervals of every
12 months, or every 20,000 km.
Cabin Overheat Protection The climate control system can reduce cabin
temperatures in extremely hot ambient conditions for a period of up to twelve hours
after you exit Model S. When enabled, air
conditioning turns on when cabin
temperatures exceed 40

Service Intervals
Regular maintenance is the key to ensuring
the continued reliability and
efficiency of your
Model S.
Rotate the tires every 10,000 km. Maintain the
correct tire pressures, and take Model S to Tesla at the regularly scheduled maintenance
intervals of every 12 months, or every
20,000 km, whichever comes
first. It is also
important to perform the daily and monthly
checks described below.
Model S should be serviced by
Tesla-certifiedtechnicians. Damages or failures caused by
maintenance or repairs performed by non- Tesla
certified technicians are not covered by
the warranty.
Daily Checks
Page 160 of 195

Removing the Maintenance PanelTo check
fluid levels, remove the maintenance
panel:
1. Open the hood.
2. Pull the maintenance panel upward to
release the clips that hold it in place.
Caution: The maintenance panel protects
the front trunk from water. When re-
attaching, make sure it is fully seated.
Checking Battery Coolant
If the quantity of
fluid in the cooling system
drops below the recommended level, the
instrument panel displays a warning message.
Stop driving Model S as soon as safety
permits and contact Tesla.
Fluid Level Check
Tesla checks the Battery coolant level at the
regularly scheduled maintenance intervals.
On a single motor Model S, you can check the
fluid level visually. BUT DO NOT REMOVE THE
FILLER CAP AND DO NOT ADD FLUID. Doing
so can result in damage not covered by the
warranty.To check the
fluid level, park Model S
on level ground. When Model S is cool, remove
the maintenance panel (see Removing the
Maintenance Panel on page 159). The
fluidlevel can be seen by looking at the outside
marks on the side of the reservoir.
The fluid level should be between the MIN and
the MAX marks. If you notice that the fluidlevel has dropped significantly, contact Tesla
before using Model S.
Do Not Top Up Battery Coolant
Warning: Battery coolant can be
hazardous and can irritate eyes and skin.
Under no circumstances should you
remove the
filler cap and/or add coolant.
If the instrument panel warns you that the
fluid level is low, contact Tesla
immediately.
To maximize the performance and life of the
Battery, the cooling system uses a specificmixture of G-48 ethylene-glycol coolant
(HOAT). Contact Tesla for more specificinformation about the coolant.

Checking Brake FluidWarning: Contact Tesla immediately if
you notice increased movement of the brake pedal or a
significant loss of brakefluid. Driving under these conditions can
result in extended stopping distances or complete brake failure.
The 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 at the
regularly scheduled maintenance intervals. To
check it yourself, park Model S on level
ground. When Model S is cool, remove the
maintenance panel (see Removing the
Maintenance Panel on page 159).
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. Tesla service
does this when you bring Model S in for
regular servicing. 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.
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
