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.
